技术领域Technical field

本发明涉及电力领域，具体而言，涉及一种接触器的无弧分断装置、接触器及无弧分断方法。The present invention relates to the field of electric power, and in particular to an arcless breaking device, a contactor and an arcless breaking method for a contactor.

背景技术Background technique

交流接触器是一种用来远距离、频繁地接通和分断交流主电路及大容量控制电路的电器，是电力拖动控制***中最重要也是最常用的控制电器。普通交流接触器分断过程中会在大分断电流的影响下产生强烈的电弧。随着新材料、新工艺的发展，交流接触器的机械寿命大幅度提高，只有机械寿命1/5至1/20的电气寿命成为影响接触器实际使用寿命的关键因素。交流接触器实现无弧分断可以大幅度提升接触器使用寿命，同时，交流接触器的可靠性、安全性、节能性也得以提高。总之，对接触器分断过程进行无弧化改造具有重大意义。The AC contactor is an electrical appliance used to remotely and frequently switch on and off the AC main circuit and the large-capacity control circuit. It is the most important and most commonly used control device in the electric drive control system. In the process of breaking the common AC contactor, a strong arc is generated under the influence of the breaking current. With the development of new materials and new processes, the mechanical life of AC contactors has been greatly improved, and only the electrical life of mechanical life of 1/5 to 1/20 has become a key factor affecting the actual service life of contactors. The AC contactor achieves arc-free breaking, which can greatly improve the service life of the contactor. At the same time, the reliability, safety and energy saving of the AC contactor are also improved. In short, it is of great significance to carry out the arcless transformation of the contactor breaking process.

混合式交流无弧接触器通过在交流接触器主触头并联可控硅的方式，实现了交流接触器无弧接通与分断，有效提升了交流接触器的电气寿命。但现有混合式交流无弧接触器触发可控硅必须专门配置如变压器或开关电源等独立电源，或通过从控制端直接取电进行阻容降压后给回路提供触发信号等，技术上虽然可行，但是均存在触发***、回路比较复杂的弊端，由此造成的制造成本提高、设计难度大、可靠性及耐用性随之下降等问题极大限制了混合式交流无弧接触器的设计、生产及应用。综上，现有技术中存在接触器易发电弧现象的技术问题。The hybrid AC arcless contactor realizes the arc contact and disconnection of the AC contactor by connecting the thyristor in parallel with the main contact of the AC contactor, thereby effectively improving the electrical life of the AC contactor. However, the existing hybrid AC arcless contactor triggering the thyristor must be specially configured with an independent power source such as a transformer or a switching power supply, or a trigger signal is provided to the loop by directly taking power from the control terminal, and the circuit is provided with a trigger signal. It is feasible, but there are drawbacks of the trigger system and the loop is complicated. The resulting manufacturing cost increase, design difficulty, reliability and durability are greatly reduced, which greatly limits the design of the hybrid AC arcless contactor. Production and application. In summary, there is a technical problem in the prior art that the contactor is prone to arcing.

针对上述的问题，目前尚未提出有效的解决方案。In response to the above problems, no effective solution has been proposed yet.

图1示出了一种根据本发明实施例的接触器的无弧分断装置的结构示意图，如图1所示，该接触器包括第一静触头11、第二静触头12和第一动触头13，该无弧分断装置包括：双向可控硅14，双向可控硅的T1端15与第二静触头的第一子触点16对应设置，双向可控硅的T2端17与第二静触头的第二子触点18对应设置；弹簧19，一端与接触器的第一动触头13连接，另一端与双向可控硅的G端相连接；其中，第一静触头11和第二静触头12通过导线连接，在接触器的控制端通电时，第一静触头11与第一动触头13接触导电；在接触器的控制端断电时，由于第一动触头13的运动，使第一静触头11与第一动触头13间的接触面积不断减小，接触电阻随接触面的减小而增大，第一静触头11与第一动触头13间产生接触电压，该电压加载在双向可控硅的T1端15和G端之间，使双向可控硅14的T1端15和G端回路中产生触发电流。同时由于双向可控硅14的T1端15和T2端17并联于第一静触头11与第一动触头13之间，双向可控硅14的T1端15和T2端17加载有主电路压降。当双向可控硅14满足导通条件，，以使得双向可控硅14在第一静触头11与第一动触头13分断前先期导通。1 is a schematic structural view of an arcless breaking device of a contactor according to an embodiment of the present invention. As shown in FIG. 1, the contactor includes a first stationary contact 11, a second stationary contact 12, and a first The movable contact 13, the arcless breaking device comprises: a triac 14, the T1 end 15 of the triac is correspondingly arranged with the first sub-contact 16 of the second stationary contact, and the T2 end 17 of the triac Corresponding to the second sub-contact 18 of the second static contact; the spring 19 has one end connected to the first movable contact 13 of the contactor and the other end connected to the G end of the triac; wherein, the first static The contact 11 and the second stationary contact 12 are connected by wires. When the control end of the contactor is energized, the first fixed contact 11 is in contact with the first movable contact 13; when the control end of the contactor is powered off, The movement of the first movable contact 13 causes the contact area between the first fixed contact 11 and the first movable contact 13 to continuously decrease, and the contact resistance increases as the contact surface decreases, and the first fixed contact 11 and A contact voltage is generated between the first movable contacts 13 and is applied between the T1 terminal 15 and the G terminal of the triac to make the T1 terminals 15 and G of the triac 14 Circuit trigger current is generated. At the same time, since the T1 terminal 15 and the T2 terminal 17 of the triac 14 are connected in parallel between the first stationary contact 11 and the first movable contact 13, the T1 terminal 15 and the T2 terminal 17 of the triac 14 are loaded with a main circuit. Pressure drop. When the triac 14 satisfies the conduction condition, the triac 14 is turned on before the first stationary contact 11 and the first movable contact 13 are disconnected.

本发明实施例提供了接触器的无弧分断装置，其中，该接触器包括第一静触头、第二静触头和第一动触头，该无弧分断装置包括双向可控硅，设置在双向可控硅的T1端与第二静触头的第一子触点对应设置，双向可控硅的T2端与第二静触头的第二子触点对应设置；弹簧，一端与接触器的第一动触头连接，另一端与双向可控硅的G端相连接；其中，第一静触头和所述第二静触头通过导线连接，在接触器的控制端通电时，第一静触头与第一动触头接触导电；在接触器的控制端断电时，第一静触头和第一动触头断开的接触电阻所产生的电压通过弹簧、导线及第二静触头加载在双向可控硅的T1和G端、T1和T2端，以使得双向可控硅导通，从而解决了现有技术中的接触器易发电弧现象的技术问题，进而达到了在接触器分断过程中无弧的技术效果。Embodiments of the present invention provide an arcless breaking device for a contactor, wherein the contactor includes a first static contact, a second static contact, and a first movable contact, and the arcless breaking device includes a bidirectional thyristor, and the setting The T1 end of the triac is correspondingly disposed with the first sub-contact of the second stationary contact, and the T2 end of the triac is correspondingly disposed with the second sub-contact of the second stationary contact; the spring, one end is in contact with The first moving contact of the device is connected, and the other end is connected to the G end of the triac; wherein the first static contact and the second static contact are connected by wires, when the control end of the contactor is energized, The first static contact is in contact with the first movable contact; when the control end of the contactor is powered off, the first static contact and the first movement The voltage generated by the contact resistance of the contact is broken by the spring, the wire and the second static contact at the T1 and G terminals, T1 and T2 terminals of the triac, so that the triac is turned on, thereby solving the problem. The technical problem that the contactor in the prior art is prone to arcing phenomenon further achieves the technical effect of no arc during the breaking process of the contactor.

可选地，图1示出的接触器的无弧分断装置中，双向可控硅及其触点结构集成于传统接触器之外的模块中，通过与接触器卡扣连接，可以实现内部结构与接触器的同步机械动作，从而实现了接触器的无弧分段，以及在静态时双向可控硅与主电路的电气隔离。Optionally, in the arcless breaking device of the contactor shown in FIG. 1, the triac and its contact structure are integrated in a module other than the conventional contactor, and the internal structure can be realized by being buckled with the contactor. Synchronous mechanical action with the contactor, thereby achieving arc-free segmentation of the contactor and electrical isolation of the triac from the main circuit during static operation.

具体地，当接触器控制端加电时，电磁线圈得电，接触器衔铁吸合，并带动上部通过卡扣连接的双向可控硅及动触点结构向下运动，由于双向可控硅及触点结构与其与第二静触头的距离小于接触器的第一动触头、与第一静触头的距离，同时因双向可控硅结构并联于接触器主触点结构两端，故双向可控硅T1、T2端先期加电。但是，由于双向可控硅的G端无电流触发，因此主电路并不导通。当接触器动触点结构继续向下运动至接触第一静触头时，主电路电流通过接触器的第一动触头和第一静触头，使电路导通，动触点继续压紧直至达到稳定状态。Specifically, when the control end of the contactor is powered, the electromagnetic coil is energized, the contactor armature is attracted, and the two-way thyristor and the movable contact structure connected by the snap connection are driven downward, due to the triac and The contact structure and the distance from the second static contact are smaller than the distance between the first movable contact of the contactor and the first fixed contact, and at the same time, because the two-way thyristor structure is connected in parallel to the two ends of the contactor main contact structure, The two-way thyristor T1 and T2 terminals are powered up first. However, since the G terminal of the triac has no current trigger, the main circuit is not turned on. When the contactor moving contact structure continues to move downward to contact the first stationary contact, the main circuit current passes through the first movable contact and the first fixed contact of the contactor, the circuit is turned on, and the movable contact continues to be pressed. Until it reaches a steady state.

进一步，当接触器控制端断电时，电磁线圈失电，接触器的压紧弹簧带动接触器衔铁释放，并带动上部通过卡扣连接的双向可控硅及动触头结构向上运动，由于此时双向可控硅及触头结构的拉紧行程大于接触器第一动触头和第一静触头的压紧行程，故接触器第一动触头和第一静触头将先期分开，当机构继续运动，接触器第一动触头和第一静触头尚未完全分开，此时第一动触头和第一静触头将产生较大的接触电阻，此时主电路并未分离，使双向可控硅T1及G端之间形成回路，产生一瞬时触发电流，同时由于接触电阻的存在，双向可控硅T1、T2端之间加载有主电路压降，该门级触发电流及双向可控硅T1、T2端电压使双向可控硅瞬时导通，主电路电流通过双向可控硅T1、T2端流过，从而使得接触器第一动触头和第一静触头分断过程中完全不会产生电弧。当接触器动触点结构继续向上运动时，第一动触头和第一静触头已实现分断，双向可控硅G端再无触发信号产生，流经双向可控硅主电路的电流在主电路交流电流过零(对于50Hz交流电最长时间为10ms，即交流电半个波)后自然过零关断，随后，双向可控硅两端触点也与主电路断开，上述整个过程可以使接触器无电弧产生。Further, when the contactor control terminal is powered off, the electromagnetic coil is de-energized, and the pressing spring of the contactor drives the contactor armature to release, and drives the upper two-way thyristor and the movable contact structure to be moved upward by the snap connection, When the tensioning stroke of the two-way thyristor and the contact structure is greater than the pressing stroke of the first moving contact and the first static contact of the contactor, the first moving contact and the first static contact of the contactor will be separated in advance. When the mechanism continues to move, the first moving contact and the first static contact of the contactor are not completely separated, and the first moving contact and the first static contact will generate a large contact resistance, and the main circuit is not separated at this time. A loop is formed between the T1 and the G terminals of the triac to generate a transient trigger current. At the same time, due to the presence of the contact resistance, a main circuit voltage drop is applied between the T1 and T2 terminals of the triac, and the gate trigger current is generated. And the voltage of the T1 and T2 terminals of the two-way thyristor makes the bidirectional thyristor instantaneously conduct, and the current of the main circuit flows through the T1 and T2 ends of the bidirectional thyristor, thereby breaking the first movable contact and the first static contact of the contactor. There is no arc at all during the process. When the contactor moving contact structure continues to move upward, the first movable contact and the first fixed contact have been disconnected, and the triac thyristor G end has no trigger signal generated, and the current flowing through the bidirectional thyristor main circuit is The main circuit AC current zero-crossing (10ms for the maximum time of 50Hz AC, that is, half of the AC power) is naturally zero-crossed. Then, the two-way thyristor contacts are also disconnected from the main circuit. The whole process can be The contactor is generated without an electric arc.

需要说明的是，接触器可以有多对第一静触头，每对静触头都连接有一个双向可控硅，例如，某个接触器有三对第一静触头，则该三对静触头中的每对静触头均可连接本申请实施例中的无弧分断装置。It should be noted that the contactor may have a plurality of pairs of first static contacts, and each pair of static contacts is connected with a two-way thyristor. For example, if one contactor has three pairs of first static contacts, the three pairs of statics Each pair of the static contacts of the contacts can be connected to the arcless breaking device in the embodiment of the present application.

It should be noted that FIG. 2(a) ) is a front view of the two-way thyristor, 2(b) is a top view of the triac, as shown in FIG. 2(a) or FIG. 2(b), the triac includes a triac 21, a T1 end 22 of the triac, and a bidirectional The T2 terminal 23 of the thyristor, the two

bidirectional contacts

24 and 25 in the vertical direction of the triac, and the G terminal 26 of the triac. The triac can be disposed on the strip insulating spacer 27.

可选地，弹簧与双向可控硅固定连接的一端设置有固定装置，与双向可控硅G端相应的固定装置相匹配。该固定装置可以由定位件、紧固件等组成。Optionally, one end of the spring and the two-way thyristor fixed connection is provided with a fixing device matched with a corresponding fixing device of the G-side of the triac. The fixture may be comprised of a locating member, a fastener, or the like.

A conductive sliding piece 193 may be disposed between the tension spring 191 and the pressing spring 192. The conductive sliding piece 193 may be coupled to the upper end piece and the lower end piece may be pressed.

可选地，双向可控硅的T1端与第二静触头的第一子触点之间的距离小于第一动触头与第一静触头之间的距离。具体地，由于双向可控硅及触点结构与其静触头的距离小于接触器动、静触头的距离，同时因双向可控硅结构并联于接触器主触头结构两端，故双向可控硅T1、T2端先期加电，此外，由于双向可控硅的G端无电流触发，主电路并不导通。Optionally, the distance between the T1 end of the triac and the first sub-contact of the second stationary contact is smaller than the distance between the first movable contact and the first stationary contact. Specifically, since the distance between the two-way thyristor and the contact structure and the static contact is smaller than the distance between the movable and static contacts of the contactor, and the two-way thyristor structure is connected in parallel to the two ends of the contactor main contact structure, the two-way can be The T1 and T2 terminals of the silicon control are energized in advance. In addition, since the G terminal of the triac has no current trigger, the main circuit is not turned on.

可选地，图4示出了另一种根据本发明实施例的一种接触器的无弧分断装置的电路示意图，如图4所示，双向可控硅包括第一双向可控硅Triac1和第二双向可控硅Triac2，无弧分断装置还包括：第一发光二极管Led1，第一发光二极管Led1的一端与第一双向可控硅Triac1的T2端相连接，第一发光二极管Led1的另一端与第二双向可控硅Triac2的T1端相连接；第二发光二极管Led2，第二发光二极管Led2的一端与第一双向可控硅Triac1的T1端相连接，第二发光二极管Led2的另一端与第一双向可控硅Triac1的T2端相连接。Optionally, FIG. 4 is a circuit diagram of another arcless breaking device of a contactor according to an embodiment of the present invention. As shown in FIG. 4, the triac includes a first triac Triac1 and The second triac Triac2, the arcless breaking device further includes: a first light emitting diode Led1, one end of the first light emitting diode Led1 is connected to the T2 end of the first triac Triac1, and the other end of the first light emitting diode Led1 Connected to the T1 end of the second triac Triac2; the second LED Led2, one end of the second LED Led2 is connected to the T1 end of the first triac Triac1, and the other end of the second LED Led2 is The T2 end of the first triac Triac1 is connected.

具体地，发光二极管可用于指示双向可控硅的故障状态，例如，在主电路L1、L2加电，接触器主触头KM1、KM2处于断开状态之下，当第一发光二极管常亮时，其指示与第一发光二极管串联的第一双向可控硅发生故障；当第二发光二极管未亮时，其指示与第二发光二极管串联的第二双向可控硅未发生故障，需要说明的是，发光二级管的显示时间、显示颜色、显示亮度以及指示规则等在此不做赘述。In particular, the light emitting diode can be used to indicate the fault state of the triac, for example, when the main circuit L1, L2 is powered, the contactor main contacts KM1, KM2 are in the off state, when the first LED is always on Demonstrating that the first triac in series with the first LED fails; when the second LED is not lit, indicating that the second triac in series with the second LED does not fail, need to be explained Yes, the display time, display color, display brightness, and indication rules of the light-emitting diodes are not described herein.

可选地，仍如图4所示，无弧分断装置还包括：第一限流电阻R1，与第一发光二极管Led1串联，设置在第一双向可控硅Triac1的T2和第二双向可控硅Triac2的T1端之间；第二限流电阻R2，与第二发光二极管Led2串联，设置在第一双向可控硅Triac1的T1端和第一双向可控硅Triac1的T2端之间。Optionally, as shown in FIG. 4, the arcless breaking device further includes: a first current limiting resistor R1, and the first light emitting diode The pole tube Led1 is connected in series between the T2 of the first triac Triac1 and the T1 end of the second triac Triac2; the second current limiting resistor R2 is connected in series with the second LED Led2, and is disposed in the first bidirectional Between the T1 end of the thyristor Triac1 and the T2 end of the first triac Triac1.

可选地，图5(a)和图5(b)示出了根据本发明实施例的接触器的无弧分断装置的波形图，用以详细描述接触器的无弧分断过程中，连接该接触器的动、静触头的示波器上可以显示的波形变化情况。5(a) and 5(b) are diagrams showing waveforms of an arcless breaking device of a contactor according to an embodiment of the present invention, for describing in detail the arcless breaking process of the contactor, connecting the The waveform changes that can be displayed on the oscilloscope of the contactor's moving and static contacts.

可选地，图5(a)示出了一种无灭弧措施的传统接触器的分断过程的波形图，如图5(a)所示，示波器的表笔接触普通交流接触器的动、静触头，经实验可以测得完整的闭合、分断过程的波形图。具体地，在接触器触头分开的瞬间，由于触头拉弧致使触头两端产生较大的弧电压(指动、静触头两端从起弧直到电弧被动、静触头分离运动所拉断的过程中动、静触头两端的压降)。需要说明的是，此时示波器量程为20V每格，不同实验所产生的电压存在差异。Optionally, FIG. 5( a ) shows a waveform diagram of a breaking process of a conventional contactor without an arc extinguishing measure, as shown in FIG. 5( a ), the stylus pen touches the dynamic and static of the common AC contactor. The contact, the waveform of the complete closing and breaking process can be measured through experiments. Specifically, at the moment when the contacts of the contactor are separated, a large arc voltage is generated at both ends of the contact due to the arc being pulled by the contact (the two ends of the finger and the static contact are arcing until the arc is passive, and the static contact is separated. The pressure drop across the moving and stationary contacts during the breaking process). It should be noted that at this time, the oscilloscope range is 20V per cell, and the voltage generated by different experiments is different.

可选地，图5(b)示出了一种根据本发明实施例的接触器的无弧分断装置的分断过程的波形图，如图5(b)所示，示波器表笔接驳无弧交流接触器的动、静触头(也就是双向可控硅的G端和T2端)，经实验可以测得完整的闭合、分断过程的波形图。具体地，在接触器触头分开瞬间，由于双向可控硅并联在动、静触头两端，同时双向可控硅的G端连接在动触头上，动、静触头的分断过程给双向可控硅的导通提供了条件，主电路电流在动、静触头分离瞬间被转移到双向可控硅上，使动、静触头分离过程不具备起弧条件，从而实现无弧。需要说明的是，此时示波器量程为1V每格；不同实验时产生的电压基本无差异，并取决于双向可控硅门级触发电压。Optionally, FIG. 5(b) shows a waveform diagram of a breaking process of the arcless breaking device of the contactor according to the embodiment of the present invention. As shown in FIG. 5(b), the oscilloscope is connected to the arcless communication. The dynamic and static contacts of the contactor (that is, the G and T2 ends of the triac) can be measured by the experiment to complete the waveform diagram of the closing and breaking process. Specifically, when the contactor contacts are separated, the two-way thyristor is connected in parallel at both ends of the movable and static contacts, and the G-end of the two-way thyristor is connected to the movable contact, and the breaking process of the moving and static contacts is given. The conduction of the two-way thyristor provides conditions, and the main circuit current is transferred to the two-way thyristor at the moment of separation of the moving and static contacts, so that the separation process of the moving and static contacts does not have the arcing condition, thereby achieving arc-free. It should be noted that the oscilloscope range is 1V per cell at this time; the voltage generated in different experiments is basically no difference, and depends on the trigger voltage of the triac gate level.

可选地，图6(a)和图6(b)示出了另一种根据本发明实施例的接触器的无弧分断装置的波形图，用以进一步描述接触器的无弧分断过程中，连接该接触器触头两端及负载两端的示波器上可以显示的波形变化情况。Optionally, FIG. 6(a) and FIG. 6(b) show waveform diagrams of another arcless breaking device of the contactor according to an embodiment of the present invention to further describe the arcless breaking process of the contactor. The waveform change that can be displayed on the oscilloscope connecting the two ends of the contactor and the load.

可选地，图6(a)示出了另一种无灭弧措施的传统接触器的分断过程的波形图。如图6(a)所示，示波器一只表笔接在接触器某相主触头两端得到波形1，同时，示波器另一只表笔接在负载两端得到波形2，经实验测得完整的分断过程的波形图(为方便观察，示波器表笔均用×10档)。可以看到，当分断主电路时，波形1即接触器某相主触头两端的电压有一个短暂的陡然上升现象，同时，负载两端的电压也有下降。这是因为传统接触器在分断过程中，随着动、静触头逐渐分离，动触头的运动，使动、静触点间的接触面不断减小，在电路中动、静触头两端形成压降，使得负载两端电压也相应降低。随着动、静触头进一步分离，由于在动、静触点之间很小的接触面间存在很大的电流密度，动、静触头分开时，该电流瞬间击穿空气，形成电弧，而随着动触头进一步运动，直到电弧被拉断，波形1即接触器主触头两端的电压才呈现正常的交流波形，而此时电路也才被真正切断，波形2回到零点。Alternatively, Fig. 6(a) shows a waveform diagram of the breaking process of another conventional contactor without the arc extinguishing measure. As shown in Fig. 6(a), one oscilloscope is connected to the two ends of the main contact of the contactor to obtain the waveform 1. At the same time, the other oscilloscope is connected to the two ends of the load to obtain the waveform 2, which is completely measured by the experiment. The waveform diagram of the breaking process (for the convenience of observation, the oscilloscope meter is used with ×10 files). It can be seen that when the main circuit is disconnected, the waveform 1 has a brief abrupt rise in the voltage across the main contacts of a phase of the contactor, and the voltage across the load also drops. This is because the traditional contactor gradually separates with the moving and static contacts during the breaking process, and the moving contact moves the contact surface between the moving and static contacts continuously, and the moving and static contacts in the circuit A voltage drop is formed at the end so that the voltage across the load is also reduced accordingly. As the moving and static contacts are further separated, since there is a large current density between the small contact faces between the moving and static contacts, when the moving and static contacts are separated, the current instantaneously penetrates the air to form an arc. With the move The contact moves further until the arc is pulled off, and the waveform 1 is the normal AC waveform at the voltage across the main contact of the contactor, and the circuit is actually cut off, and the waveform 2 returns to zero.

可选地，图6(b)示出了另一种根据本发明实施例的接触器的无弧分断装置的分断过程的波形图，如图6(b)所示，示波器一只表笔接在接触器某相主触头两端得到波形1，同时，示波器另一只表笔接在负载两端得到波形2，经实验测得完整的分断过程的波形图(为方便观察，示波器表笔均用×10档)。可以看到，当分断主电路时，波形1即接触器某相主触头两端的电压总是过零后自然关断，同时，负载两端的电压也是从零电压点开始接通。这是因为，采用了本发明无弧分断方法的无弧接触器，当分断时，由于动触头的运动，接触电阻的增大导致的动、静触头两端压降给双向可控硅的导通提供了条件，使双向可控硅在动、静触头分离时刻前导通，等到电流经过零点，且构成双向可控硅导通的条件不再能够使双向可控硅导通时，电路自然过零关断，从而形成过零分断的波形图。可以想到，在图中所示分段点之前半个波内的某个时间点，接触器动、静触头事实上已经分开。Optionally, FIG. 6(b) shows a waveform diagram of another breaking process of the arcless breaking device of the contactor according to the embodiment of the present invention. As shown in FIG. 6(b), an oscilloscope is connected to a meter. Waveform 1 is obtained at both ends of the main contact of one phase of the contactor. At the same time, the other instrument of the oscilloscope is connected to the two ends of the load to obtain the waveform 2. The waveform of the complete breaking process is measured by experiments (for the convenience of observation, the oscilloscope is used × 10 files). It can be seen that when the main circuit is disconnected, the waveform 1 is the voltage across the main contact of a phase of the contactor, and the voltage across the main contact is always turned off, and the voltage across the load is also turned on from the zero voltage point. This is because the arcless contactor adopting the arcless breaking method of the present invention, when breaking, the pressure drop across the moving and static contacts caused by the movement of the movable contact, the contact voltage is increased to the two-way thyristor. The conduction provides conditions for the triac to conduct before the moment of separation of the moving and stationary contacts, until the current passes through the zero point, and the condition that the triac is turned on can no longer enable the triac to be turned on. The circuit naturally turns off zero-crossing, thus forming a waveform diagram of zero-crossing.

The voltage generated by the contact resistance is applied to the T1 terminal 44 and the G terminal, the T1 terminal 44 and the T2 of the triac through the spring 40 and the T1 terminal 44 and the T2 terminal 47 of the triac 43. Between 47 to 43 so that the triac is turned on.

具体地，当接触器控制端加电时，电磁线圈得电，接触器衔铁吸合，并带动可控硅及动触头结构向下运动，由于可控硅及触头结构处于接触器第一动触头和第一静触头之间，同时并联于接触器主触点结构两端，故可控硅T1、T2端先期加电，但由于G端无电流触发，主电路并不导通，此时可控硅及触头结构处于压紧状态。当接触器动触点结构继续向下运动并接触可控硅两边的双向触点结构时，主电路电流通过接触器第一动触头和第一静触头，使主电路导通，第一动触头继续压紧，直至达到稳定状态。Specifically, when the contactor control terminal is powered, the electromagnetic coil is energized, the contactor armature is attracted, and the thyristor and the movable contact structure are driven to move downward, because the thyristor and the contact structure are in the contactor first The movable contact and the first fixed contact are simultaneously connected at both ends of the contactor main contact structure, so the thyristors T1 and T2 are energized in advance, but since the G terminal has no current trigger, the main circuit is not turned on. At this time, the thyristor and the contact structure are in a compact state. When the contactor moving contact structure continues to move downward and contacts the two-way contact structure on both sides of the thyristor, the main circuit current passes through the first movable contact and the first fixed contact of the contactor, so that the main circuit is turned on, first The moving contact continues to be pressed until it reaches a steady state.

进而，当接触器控制端断电时，电磁线圈失电，接触器主压紧弹簧带动接触器衔铁释放，并带动接触器第一动触头、可控硅及触头结构向上运动，由于可控硅及触头结构处于接触器第一动触头和第一静触头之间，故接触器第一动触头将先期分开，当机构继续运动，接触器第一动触头与下部处于压紧状态的可控硅两端的双向触点将分未分，此时将在其间产生较大的接触电阻，但此时主电路并未分离，因此使可控硅T1及G端之间形成回路，产生瞬时触发电流，同时由于接触电阻的存在，双向可控硅T1、T2端之间加载有主电路压降，该门级触发电流及双向可控硅T1、T2端电压使双向可控硅瞬时导通，主电路电流通过可控硅T1、T2端流过，从而使得接触器第一动触头与下部处于压紧状态的双向可控硅及触头结构分断过程中完全不会产生电弧。当接触器动触点结构继续向上运动时，第一动触头已实现分断，可控硅G端再无触发信号产生，流经可控硅主电路的电流在主电路交流电流过零(对于50Hz交流电最长时间为10ms，即交流电半个波)后自然过零关断，随后，可控硅两端触点也会与主电路断开，上述整个过程可以使接触器无电弧产生。Furthermore, when the contactor control terminal is powered off, the electromagnetic coil loses power, and the contactor main compression spring drives the contactor The iron is released and drives the first moving contact of the contactor, the thyristor and the contact structure to move upward, since the thyristor and the contact structure are between the first movable contact and the first fixed contact of the contactor, so that the contact The first moving contact will be separated in advance, and when the mechanism continues to move, the two-way contact between the first moving contact of the contactor and the thyristor at the lower pressing state will be divided, and a larger one will be generated therebetween. The contact resistance, but the main circuit is not separated at this time, so that a loop is formed between the T1 and the G terminal of the thyristor to generate a transient trigger current, and at the same time, due to the existence of the contact resistance, the TAC and the T2 end are loaded. There is a main circuit voltage drop, the gate-level trigger current and the voltage of the T1 and T2 terminals of the triac enable the bidirectional thyristor to be turned on instantaneously, and the main circuit current flows through the T1 and T2 terminals of the thyristor, thereby making the contactor first. There is no arc at all during the breaking process of the moving contact and the two-way thyristor and the contact structure in which the lower part is pressed. When the contactor moving contact structure continues to move upward, the first moving contact has been disconnected, and the thyristor G terminal has no trigger signal generated, and the current flowing through the thyristor main circuit is zero crossing in the main circuit alternating current (for The maximum time of 50 Hz AC is 10 ms, that is, half of the alternating current, and then the natural zero-crossing is turned off. Then, the contacts at both ends of the thyristor are also disconnected from the main circuit. The above process can cause the contactor to generate no arc.

可选地，双向可控硅的T1端与第一子触点之间的距离小于双向可控硅的T1端与第三子触点之间的距离，并且，双向可控硅的T1端与双向可控硅的T2端处于相同的水平面。T1端和T2端处于同一水平面可以确保在与第一静触头的子触点接触时保持同时性和一致性。Optionally, the distance between the T1 end of the triac and the first sub-contact is less than the distance between the T1 end and the third sub-contact of the triac, and the T1 end of the triac is The T2 ends of the triac are at the same level. The T1 end and the T2 end are at the same level to ensure simultaneity and consistency when in contact with the sub-contacts of the first stationary contact.

When the control terminal of the contactor is powered off, the voltage generated by the contact resistance of the first static contact and the first movable contact is loaded in the two-way through the spring and the T1 end and the T2 end of the triac. The T1 terminal and the G terminal, the T1 terminal and the T2 terminal of the silicon control are controlled so that the triac is turned on.

可选地，该接触器可以有多对第一静触头，每对静触点都连接有一个双向可控硅，例如，某个接触器有三对第一静触头，则该三对静触点中的每对静触点均可连接本申请实施例中的无弧分断装置。可选地，接触器在无弧分断过程中的工作原理简述如下：在接触器主触头分段过程中，由于动触头的运动，使动、静触头间的接触面不断减小，电流密度不断增大，接触电阻随接触面的减小而越来越大，从而使得其间产生接触电压Vt，该电压加载在双向可控硅的T1端和G端两端，使回路中产生电流It，当回路中电流强度大于双向可控硅的门级触发电流I_GT时，可控硅瞬时导通。由于可控硅导通速度极短，使得接触器动触点开始离开静触点并产生电弧之前双向可控硅已经先期导通，从而使分断过程不会产生电弧。Optionally, the contactor may have a plurality of pairs of first static contacts, and each pair of static contacts is connected with a triac. For example, if a contactor has three pairs of first static contacts, the three pairs of statics Each pair of static contacts in the contacts can be connected to the arcless breaking device in the embodiment of the present application. Optionally, the working principle of the contactor in the arcless breaking process is briefly described as follows: during the segmentation process of the main contact of the contactor, the contact surface between the moving and static contacts is continuously reduced due to the movement of the moving contact. The current density is continuously increased, and the contact resistance is larger and larger as the contact surface is reduced, so that a contact voltage Vt is generated therebetween, and the voltage is applied to the T1 end and the G end of the bidirectional thyristor to generate a loop. Current It, when the current intensity in the loop is greater than the gate-level trigger current I _GT of the triac, the thyristor is momentarily turned on. Since the thyristor conduction speed is extremely short, the triac is turned on before the movable contact of the contactor starts to leave the static contact and an arc is generated, so that the arcing process does not occur.
