Abstract
The utility model relates to a dual-power-power automatic change-over switch, which comprises a motor, a transmission mechanism, a control shaft, a control rod and a main switch, wherein the motor is in linkage connection with the control shaft through the transmission mechanism, one end of the control rod is connected onto the control shaft, the other end of the control rod is in linkage connection with a circuit breaker handle in the main switch, the control rod is linked with the main switch through the control shaft, the motor is a synchronous motor, the transmission mechanism is a linkage gear group, and the synchronous motor is in linkage connection with the control shaft through the linkage gear group. The motor adopts the synchronous motor and is linked with the control shaft through the linkage gear group consisting of two gears, the rotation speed of the synchronous motor is lower, the rotation speed required when the dual-power-power automatic change-over switch acts can be reached without great gear ratio, the structure of the linkage gear group is simplified, in addition, the assembly is convenient, and the production cost of products is greatly reduced.
Description
Technical field
The utility model relates to a kind of double power supply automatic transfer switch.
Background technology
The transmission mechanism of existing double power supply automatic transfer switch generally adopts rotating speed to reach 6000 revolutions per seconds high rotating speed series-wound motor, and the rotating speed that needs when through change gear box rotating speed being adjusted to the conversion of conversion double power supply automatic transfer switch drives Control Shaft and rotates; The control lever that connects on the Control Shaft also and then moves; Main switch is broken off or closure, but the change gear box part is various, complex structure; Cost is high, and breaks down easily.
Summary of the invention
For above-mentioned reasons, it is a kind of simple in structure that the purpose of the utility model is to provide, the double power supply automatic transfer switch of dependable performance.
For realizing above-mentioned purpose; The utility model adopts a kind of double power supply automatic transfer switch, comprises motor, transmission mechanism, Control Shaft, control lever, main switch, and motor is connected through transmission mechanism and Control Shaft; Control lever one end is connected on the Control Shaft; Circuit breaker handle in the other end and the main switch is connected, and control lever is through Control Shaft and main switch interlock, and said motor is a synchronous machine; Said transmission mechanism is the linkage gear group, and synchronous machine is connected through linkage gear group and Control Shaft.
The beneficial effect of the utility model is that motor adopts synchronous machine; And through linkage gear group and Control Shaft interlock; The synchronous machine rotating speed is lower, and the rotating speed of the needs that do not need big gear than just can reach double power supply automatic transfer switch and move the time has been simplified the structure of linkage gear group; And easy to assembly, greatly reduce production cost of products.
The utility model further is set to the linkage gear group and comprises motor gear and shaft gear, and motor gear is arranged on the output shaft of synchronous machine, and shaft gear is arranged on the Control Shaft, motor gear and shaft gear engagement.The linkage gear group includes only two pitch wheels that are separately positioned on synchronous machine and the Control Shaft, and is simple in structure, easy to assembly, stable performance.
