Description

自动转换电源的电容跳脱装置及其方法Capacitor tripping device for automatic conversion power source and method thereof 技术领域Technical field
本发明由关于电容跳脱装置(Capactor Trip Device,CTD)，尤其涉及一种自动切换输入电源的方法及其装置，其具有自动监测与转换电源的功能。当原本供电回路无法供电时，可由其它电源立即支持，而继续提供紧急辅助工作电源。The present invention relates to a Capactor Trip Device (CTD), and more particularly to a method and apparatus for automatically switching an input power source, which has the function of automatically monitoring and converting a power source. When the original power supply circuit cannot supply power, it can be immediately supported by other power sources, and continue to provide emergency auxiliary working power.
背景技术Background technique
电容跳脱装置是一种非常普遍使用的产品，但往往让人忽略它的重要性！电容跳脱装置其使用的场所，一般是在高压回路中做为高压***跳脱回路的工作电源。无论是使用在高压断路器(CB)的跳脱线圈，或者是使用在保护电驿(Relay)的工作电源，当作为电容跳脱装置失能时，也即代表高压***发生事故时，无法作动以隔离事故点，并可能发生二次事故甚或引起***、火灾。Capacitance trip devices are a very common product, but they often overlook the importance of it! The place where the capacitor trip device is used is generally used as a working power source for the high voltage system trip circuit in the high voltage circuit. Whether it is used in a tripping coil of a high-voltage circuit breaker (CB) or a working power supply used in a relay, when it is disabled as a capacitor tripping device, that is, when an accident occurs in the high-voltage system, it cannot be made. Move to isolate the accident, and may cause a secondary accident or even an explosion or fire.
高压隔离设备(H.V.CB)，是接受保护电驿的指令，做为是否跳脱高压断路器，以将主供电干线(在台湾，是指台湾电力公司的供电干线)将事故源隔离。因此该断路器如果不能如期在某一事业单位(受电方)发生短路事故时立即跳脱，将会造成高压隔离设备(H.V.CB)损坏，而扩及到影响主供电干线供应电源给其它的事业单位(受电方)，造成连锁性的产业损失。高压断路器能否及时跳脱，受控于保护电驿是否能实时发出指令，因此，当提供保护电驿的工作电源有问题时，该保护电驿就不会动作；该保护电驿就不会动作时，高压CB在事故发生时也就不会动作，无法隔离事业单位的事故点，造成严重的二次事故，甚至影响台电供电馈线跳脱！不可不慎。由于此高危险性的工安事件常因误判而产生意外，于是供电干线的业者(中国台湾电力公司)为防止电驿于短路事故时，因电压骤降无法动作触发断路器跳脱，及因比流器饱和迟缓动作，要求事业单位要按照规定装设其保护***，才会答应供电。主要的规定内容是：采比压器二次侧电源供应时，应辅以电容跳脱装置、或辅以电 容跳脱装置再并接不断电***(UPS)，且供电子式或数字式电驿使用的电容跳脱装置，不得接供断路器或其它设备使用。但这是理想，而意外常常来自于理想状况之外，实务上不断电***一年、两年后几乎都会故障，但是事业单位却不会察觉到，通常都是有短路事故时，发现高压隔离设备(H.V.CB)不会跳脱，发现不断电***无法供应工作电源给保护电驿，但为时已晚。The high-voltage isolation device (H.V.CB) is an instruction to receive the protection of the electric raft as a means of tripping off the high-voltage circuit breaker to isolate the main supply line (in Taiwan, the power supply main line of Taiwan Power Company). Therefore, if the circuit breaker cannot jump off immediately in the event of a short-circuit accident in a certain business unit (power receiving party), the high-voltage isolation device (HVCB) will be damaged, and the power supply to the main power supply mains will be expanded to other sources. The business unit (power receiving party) causes a chain of industrial losses. Whether the high-voltage circuit breaker can jump in time, controlled by whether the protection power can issue instructions in real time. Therefore, when there is a problem with the working power supply that protects the power supply, the protection power will not operate; the protection power is not When it will act, the high-pressure CB will not move when the accident occurs, and it is impossible to isolate the accident point of the public institution, causing a serious secondary accident and even affecting the Taipower power supply feeder to jump off! Don't be careless. Because this high-risk industrial safety incident often leads to accidents due to misjudgment, the operator of the mains supply line (China Taiwan Electric Power Company) can prevent the electric circuit breaker from jumping, and the circuit breaker can not jump due to the voltage dip. Due to the slow saturation of the current comparator, the public institution is required to install its protection system in accordance with the regulations, and the power supply will be promised. The main provisions are: when the secondary side power supply of the comparator is used, it should be supplemented by a capacitor trip device or supplemented with electricity. The capacitor tripping device is connected to the uninterruptible power system (UPS), and the capacitor tripping device for electronic or digital power is not used for circuit breakers or other equipment. But this is an ideal, and accidents often come from ideal conditions. In practice, the system will almost always fail after one or two years, but the public institutions will not notice that high-voltage isolation is usually found when there is a short-circuit accident. The device (HVCB) does not trip and finds that the uninterruptible power system cannot supply the working power to the protection battery, but it is too late.
但观察现有的电容跳脱装置其电源的供应来源，一般来自高压比压器的二次侧电源，而其高压比压器在环境不良，或者过载甚而事故发生时而烧毁，或者发生因吸湿而造成耐压不足而产生绝缘破坏，会造成供给电容跳脱装置的输入端没有电；或者电容跳脱装置内部主要的组件电容因时间老化衰减，皆会造成电容跳脱装置失能，无法正常供电。此时若外部无法引入其它电源如UPS交源电源或者是直流电源(例如直流盘或者其它的电容跳脱装置的电源)，会造成高压盘于***故障时，跳脱回路没有工作电源，而无法隔离事故点的严重性。However, observing the supply source of the existing capacitor tripping device, generally comes from the secondary side power supply of the high voltage comparator, and the high pressure comparator is burnt in the environment, or the overload or even the accident occurs, or occurs due to moisture absorption. Insulation damage caused by insufficient withstand voltage will cause no power at the input end of the supply capacitor tripping device; or the main component capacitance inside the capacitor tripping device will be attenuated due to time aging, which will cause the capacitor tripping device to lose power and cannot be powered normally. . At this time, if other external power sources such as UPS AC power supply or DC power supply (such as DC power supply or other power supply of the capacitor tripping device) cannot be introduced, the high voltage disc may cause the system to malfunction, and the tripping loop has no working power, and cannot Isolation of the severity of the incident.
旧有设备***中，往往都是使用盘内型固定式的电容跳脱装置，在实际状况下，更换以及换修配线不是很容易，况且在盘内固定式维护保养时，必须打开高压盘的盘门，常常会因此而发生感电事故，有鉴于安全上的考虑，日后可能也必须移至盘面上，所以为解决实际维修更换电容跳脱装置的问题，一种固定盘面两用可模块化的电容跳脱装置是必须解决的问题。In the old equipment system, the fixed-type capacitor tripping device is often used in the disk. In actual conditions, it is not easy to replace and change the wiring. Moreover, the high-voltage disk must be turned on during the fixed maintenance of the disk. The disc door often causes an electric shock accident. In view of safety considerations, it may have to be moved to the disc surface in the future. Therefore, in order to solve the problem of replacing the capacitor trip device in actual repair, a fixed disc surface dual-use module The capacitive trip device is a problem that must be solved.

The preferred embodiment is implemented as shown in FIG. 1 and has a three-dimensional box-like body 10; and an electric meter panel 11 is pivotally mounted on the body 10. The body 10 can be fixed on the disk surface; or as shown in FIG. 2, the entire capacitor trip device is detachable and detachably mounted on the switchboard surface 40. Furthermore, the body 10 is provided with a set of alternating current input terminals 21 for inputting a power source, such as a PT secondary side power source. A set of AC power input terminals 50 and a set of DC power input terminals 60 are both fixed to the body 10 of the capacitive trip device. A light can be connected to the above input terminals to know if there is power. A display light can also be connected to the direct current (DC) output of the direct current output terminal 22. All the power input terminals enter the composition of the automatic monitoring switching circuit shown in FIG. 3, and the automatic monitoring switch selects an appropriate power source, and then supplies it to the control circuit component 20 inside the capacitor tripping device. The control circuit assembly 20, as shown in FIG. 5, is fixedly preset in the body 10 of the capacitive trip device. The DC output of the control circuit assembly 20 can supply power to a circuit breaker or power port of the main power supply terminal. The capacitor tripping device is further provided with a comparison voltage circuit which is preset to have a rated voltage, such as a direct current (DC) of 80 volts.
本发明的技术思想请参考图3的自动切换控制方块示意图，与图4自动监测切换电路的电路示意图。首先提供一主交流电源单元(方块70)，供给电容跳脱装置。当该主交流电源单元具有多个交流电源输入时，设置一交流电源主控制互锁单元，譬如是电驿25，执行选择与限制只能让其中一个交流电源输入给电容跳脱装置。交流电源主控制互锁单元预设优先执行选择外来主供电干线端(PT)的二次侧电源(方块71)，供应给电容跳脱装置的自动监测切换电路组成(方块73)，以便使控制电路组件(方块20)运作。当主供电干线端(PT)的二次侧电源无法提供交流电源时，则令交流电源主控制互锁单元执行选择不断电***的电源(方块72)。先设置一比较电压电路在电容跳脱装置内，并建立一额定直流输出电压值(方块74)，以便比较侦测电容跳脱装置的直流输出电压。For the technical idea of the present invention, please refer to the schematic diagram of the automatic switching control block diagram of FIG. 3, and the circuit diagram of the automatic monitoring switching circuit of FIG. A primary AC power unit (block 70) is first provided to supply the capacitor trip device. When the main AC power unit has multiple AC power inputs, an AC power main control interlock unit, such as the power unit 25, is set, and the selection and limitation can only be performed by one of the AC power sources to the capacitor trip device. The AC power main control interlock unit presets preferentially performs selection of the secondary side power supply of the external main power supply trunk terminal (PT) (block 71), and is supplied to the automatic monitoring switching circuit of the capacitor trip device (block 73) for control The circuit component (block 20) operates. When the secondary side power supply of the mains supply rail terminal (PT) is unable to provide AC power, the AC power main control interlock unit performs power selection for the uninterruptible power system (block 72). First, a comparison voltage circuit is set in the capacitor tripping device, and a rated DC output voltage value is established (block 74) to compare the DC output voltage of the detecting capacitor trip device.
请同时参考图4自动监测切换电路组件的电路示意图，与图5控制电路组件的电路图所示，本发明还提供一辅助直流电源单元(方块75)，其输出端并联于电容跳脱 装置的直流电输出端。为了执行选择与限制只能让辅助直流电源单元或电容跳脱装置的直流电输出其中一个直流电源输出，设置一直流电源辅助控制互锁单元，譬如是电驿26的互锁接点开关2a,2b则可以解决。该直流电源辅助控制互锁单元系接受比较电压电路的控制。换言之，侦测电容跳脱装置输出的直流电压，当保持监测电压值(方块74)时，就保持由电容跳脱装置输出直流电(方块76)。但当低于比较电压电路建立的额定直流输出电压值(方块74)，譬如是低于直流(DC)80伏特时，则启动直流电源辅助控制互锁单元，以执行选择辅助直流电源单元41输出(方块75)。Please also refer to FIG. 4 for a schematic diagram of the circuit of the automatic monitoring switching circuit assembly. As shown in the circuit diagram of the control circuit component of FIG. 5, the present invention also provides an auxiliary DC power supply unit (block 75) whose output terminal is connected in parallel with the capacitor trip. The DC output of the unit. In order to perform the selection and limitation, only the DC output of the auxiliary DC power supply unit or the capacitor tripping device can be outputted from one of the DC power sources, and the DC power supply auxiliary control interlocking unit is set, for example, the interlocking contact switch 2a, 2b of the electric port 26 Can be solved. The DC power supply auxiliary control interlock unit is controlled by a comparison voltage circuit. In other words, the DC voltage output by the capacitive trip device is detected, and when the monitored voltage value is maintained (block 74), the DC output is maintained by the capacitive trip device (block 76). However, when the rated DC output voltage value (block 74) established by the comparison voltage circuit is lower than the direct current (DC) 80 volts, the DC power supply auxiliary control interlock unit is activated to perform the selection of the auxiliary DC power supply unit 41 output. (Box 75).
自动监测切换电路组件将自动侦测串连的电源主控制互锁单元、电源辅助控制互锁单元、与辅助直流电源单元三个单元，若低于比较电压电路建立的额定直流输出电压值，且全部都无法正常输出直流电源时，将供应电容跳脱装置的外接交流电源(方块77)，直接输出交流电引至外接负载(方块78)。The automatic monitoring switching circuit component will automatically detect the serial power main control interlock unit, the power auxiliary control interlock unit, and the auxiliary DC power unit, if it is lower than the rated DC output voltage value established by the comparison voltage circuit, and When all of the DC power cannot be output normally, the external AC power supply of the capacitor trip device is supplied (block 77), and the direct output AC power is led to the external load (block 78).
图4的电路示意图显示，当交流电进入即随时侦测PT二次侧电源是否有电。若是没有电源时，随即有交流电源输入端50经由接点进入到电容跳脱装置内部控制电路组件20，并输出至直流电输出端子22。当直流电输出端子22的电压值低于工作电压，且PT二次侧没有输入电源时，则由直流电源端41输入经由导通2a接点至直流电输出端子22。又当PT二次侧电源、与其它电源都没有输入电流，及直流电输出端子22的输出低于工作电压时，则可由交流电源的输入端50，外接至断路器以及电驿的工作电源。The circuit diagram of Figure 4 shows that when the AC power enters, it detects the power of the PT secondary side power supply at any time. If there is no power supply, the AC power input terminal 50 then enters the capacitor trip device internal control circuit assembly 20 via the contacts and outputs to the DC output terminal 22. When the voltage value of the DC output terminal 22 is lower than the operating voltage and there is no input power source on the secondary side of the PT, the DC power supply terminal 41 inputs the contact via the conduction 2a to the DC output terminal 22. When the PT secondary side power supply and other power sources have no input current, and the output of the DC power output terminal 22 is lower than the operating voltage, the input terminal 50 of the AC power source can be externally connected to the circuit breaker and the operating power of the power supply.

First, when the capacitor tripping device is originally installed and placed in the panel of the switchboard, in the future, The capacitor trip unit can be removed and placed on the disk surface without having to replace all wiring. Secondly, all AC power and DC currents already have inputs, and can be clearly marked, so there will be no wiring errors and burned lines.
