Abstract
The utility model relates to a three-phase contactor, which employs an intelligent modular magnetoelectric structure. The intelligent module includes an external connected power supply module, a voltage detection circuit module, a one-chip microcomputer circuit module, a driving switching circuit module and a driving circuit module. The arc extinguishing mode of the three-phase contactor is a permanent magnetic arc extinction mode, a high level is output at the power-on moment of the one-chip microcomputer, meanwhile the driving circuit voltage on two ends of the contactor solenoid is very high, the contactor is guaranteed to be reliable, rapid switching is realized latter, the driving circuit voltage on two ends of the contactor solenoid is reduced rapidly, and a maintaining state is kept. The contactor solenoid is very smart, a heavy current is provided at the power-on moment to enable the contact to be absorbed, later the voltage on two ends of the contactor solenoid is reduced rapidly, the current passing through the solenoid is reduced, the power consumption is reduced, and the three-phase contactor enters a normal work state.

Summary of the invention
The purpose of the utility model is to overcome the defective that prior art exists, and a kind of three-phase contactor is provided, and described three-phase contactor advantages of small volume, simple in structure is convenient for changing, and is low in energy consumption.
The utility model relates to a kind of three-phase contactor, and described three-phase contactor adopts intelligent object formula magnetoelectricity structure, and described intelligent object comprises the external power supply module; The voltage detecting circuit module; The single chip circuit module drives commutation circuit module and drive circuit module, and described external power supply module is connected with the voltage detecting circuit module; Described voltage detecting circuit module is connected with the single chip circuit module; Described single chip circuit module is connected with driving commutation circuit module, and described driving commutation circuit module is connected with drive circuit module, and the arc quenching method of described three-phase contactor adopts the permanent magnetism arc extinguishing.
Pass through technique scheme: increase intelligent control module, realize the reliable switching of Contactor Starting state and hold mode, use the permanent magnetism arc extinguishing instead, arc quenching effect is better, has reduced the failure rate of contactor, has prolonged useful life.
The utility model is further improved, and the auxiliary contact of described three-phase contactor adopts the close freedom from repairs type sensitive switch of full envelope, and main contact adopts the form of three groups of parallel connections.
Pass through technique scheme: the three-phase contactor auxiliary contact adopts the type sensitive switch of full sealed non-maintenance, and anti-dust storm is non-maintaining, has reduced user's maintenance cost, and the solenoid volume is small and exquisite, makes corresponding the reducing of whole contactor volume.
Description of drawings:
Fig. 1 is the utility model embodiment assembly drawing frame diagram;
Fig. 2 is the utility model embodiment assembly drawing front view;
Embodiment:
Shown in Fig. 1-2, the embodiment of the utility model is a three-phase contactor, and described three-phase contactor adopts intelligent object formula magnetoelectricity structure; Described intelligent object comprises the external power supply module, voltage detecting circuit module, single chip circuit module; Drive commutation circuit module and drive circuit module; Described external power supply module is connected with the voltage detecting circuit module, and described voltage detecting circuit module is connected with the single chip circuit module, and described single chip circuit module is connected with driving commutation circuit module; Described driving commutation circuit module is connected with drive circuit module, and the arc quenching method of described three-phase contactor adopts the permanent magnetism arc extinguishing.
The auxiliary contact 2 of described three-phase contactor adopts HKW6 type sensitive switch, and main contact 1 adopts the form of three groups of parallel connections.
Novel three-phase ac contactor and existing contactor all remain unchanged at installation dimension, installation site, lead-out wire, are convenient for changing.Arc quenching method is used the permanent magnetism arc extinguishing instead, and auxiliary contact is used instead simply small and exquisite, the sensitive switch of hermetically sealed freedom from repairs; Contactor solenoid and small and exquisite; Pass to big electric current and make its adhesive starting moment, reduce the voltage at coil two ends subsequently rapidly, the electric current through coil reduces; Power consumption reduces, and gets into normal operating conditions.
Single-chip microcomputer is exported high level at powered on moment, this moment drive circuit to be added to the voltage at contactor coil two ends also very high, guarantee the reliable of contactor, switch rapidly subsequently, be that the voltage that drive circuit is added to the contactor coil two ends reduces immediately, get into hold mode.
