Abstract
The utility model discloses a circuit breaker with the power-driven operating mechanism, belonging to the technical field of the low-voltage electrical apparatus. The main body of the circuit breaker with the power-driven operating mechanism of the utility model is a breaker; the synchronous electric machine of the poly phase permanent magnetism paw is extended between the upper of the breaker and the crank of the breaker, and a bent arm, a connecting rod and a spring are connected and matched, which forms the power-driven operating mechanism of the breaker. The power-driven operating mechanism of the utility model has high reliability, simple comprising components, easy manufacturing and low cost. The spring on the crank can effectively buffer the inertia of the power-driven operating mechanism components because of mechanical movement, and thus the service life and the operation effect of the power-driven operating mechanism are greatly increased.
Description
Technical field
The utility model belongs to the low voltage electrical apparatus technology field, is specially a kind of circuit breaker of charged pneumatic operating mechanism.
Background technology
Circuit breaker in the past is the folding of adopting manually to come the control switch handle.In recent years, medium and small power consumer prevents in the circuit breaker of person electric shock in popularization, requires energy automatic brake separating and combined floodgate on middle low capacity power distribution circuit, promptly installs electrically operated device additional on existing circuit breaker.At present in the motor-operating mechanism of circuit breaker, adopt the single-phase permanent claw electrode synchronization electromotor, motor shaft is connected with custom-designed group of key one end, dials the key other end and is connected with switch knob, the motor rotation drives group key moves forwards or backwards switch knob, realizes automatic brake separating and combined floodgate.The shortcoming of this structure is that the single-phase permanent claw electrode synchronization electromotor only is suitable for the following miniature circuit breaker of 100 peaces, produce pulsating field and pulsation moment when motor feeds alternating current, the end of moment, can reach zero, is to rely on inertia to continue rotation after pulling in, but when starting, after rotor is energized vibration,, pull in by departing from neutral position, like this can in light-load starting fashion, difficulty when heavy load starting, poor reliability, useful life is short.
The utility model content
The technical problems to be solved in the utility model provides a kind of use multi-phase permanent claw electrode synchronization electromotor, simple for structure, practical, long service life, and the circuit breaker of the low charged pneumatic operating mechanism of production cost.
The circuit breaker of charged pneumatic operating mechanism described in the utility model, agent structure are a circuit breaker, and motor links to each other with circuit breaker handle by transmission device, it is characterized in that motor is the multi-phase permanent claw electrode synchronization electromotor.
The circuit breaker of charged pneumatic operating mechanism described in the utility model is characterized in that described multi-phase permanent claw electrode synchronization electromotor is the two-phase permanent magnet claw electrode synchronization electromotor, adopts twin coil or three-winding.
The circuit breaker of charged pneumatic operating mechanism described in the utility model is characterized in that described multi-phase permanent claw electrode synchronization electromotor is the three-phase permanent claw electrode synchronization electromotor, adopts three-winding.
The circuit breaker of charged pneumatic operating mechanism described in the utility model, agent structure is a circuit breaker, it is characterized in that motor and stretches out between the circuit breaker handle of breaker upper cover connecting lever, connecting rod, spring connection cooperation, the motor-operating mechanism of formation circuit breaker.
The circuit breaker of charged pneumatic operating mechanism described in the utility model is characterized in that motor is arranged on breaker upper cover top.
The circuit breaker of charged pneumatic operating mechanism described in the utility model is characterized in that motor is arranged on the breaker upper cover bottom.
The circuit breaker of charged pneumatic operating mechanism described in the utility model is characterized in that the motor-operating mechanism outside of circuit breaker is provided with loam cake.
The circuit breaker of charged pneumatic operating mechanism described in the utility model is characterized in that motor covers on being fixedly installed on the circuit breaker.
The circuit breaker of described charged pneumatic operating mechanism of the present utility model is mainly used in residual current circuit breaker.
The multi-phase permanent claw electrode synchronization electromotor that motor-operating mechanism of the present utility model adopts, use twin coil or three-winding, feed out-of-phase current in the coil, electric current just can not be zero simultaneously in the coil like this, just the moment zero moment can not take place, and starts reliable, moment is big, stable, closing speed is fast, can promote more jumbo circuit breaker, and suitable circuit breaker scope is wide; The motor-operating mechanism building block is simple in structure, easily processing, and cost is low, and the spring on the handle can effectively cushion the inertia of electric operating parts mechanical movement, has greatly improved the useful life and the operational effect of motor-operating mechanism.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The circuit breaker of a kind of charged pneumatic operating mechanism shown in Figure 1, agent structure are a circuit breaker 8, are connected cooperation successively by connecting lever 4, connecting rod 5, spring 6 between motor 3 and the circuit breaker handle 7 that stretches out breaker upper cover 2, constitute the motor-operating mechanism of circuit breaker.Motor 3 is the two-phase permanent magnet claw electrode synchronization electromotor, adopts twin coil, can directly get two-phase power supply from circuit breaker, also can be transformed into two-phase through phase-shift circuit by getting single phase poaer supply on the circuit breaker, makes the electric current that feeds out of phase in the coil.Motor 3 is arranged on breaker upper cover 2 tops or bottom.The motor-operating mechanism outside of circuit breaker is provided with loam cake 1, covers the entire upper surface of breaker upper cover 2, and the control panel of circuit breaker is installed on the loam cake 1; Loam cake 1 also can only cover motor-operating mechanism partly, and the control panel of circuit breaker is installed on the breaker upper cover 2 or goes up on the loam cake 1.Be connected with motor 3 by control circuit, thereby 3 runnings of control motor are drawn circuit breaker handles 7 to the position that opens or closes by connecting lever 4, connecting rod 5, spring 6.
