US 2015/0029633 A1 · Miniature breaker having short circuit self-locking function and miniature breaker having position state detecting function

Abstract

Both a miniature circuit breaker with short-circuit self-locking function and a miniature circuit breaker with position state detection function include: a first miniature circuit and a miniature circuit breaker operation output device. A motor, an action unit and a control unit are located within the casing of the miniature circuit breaker operation output device. The motor outputs a torque, the action unit obtains the torque and the torque is converted into the closing or breaking operation of the first miniature circuit breaker, the control unit controls the rotation and stop of the motor. A position state detection mechanism is located within the casing of the miniature circuit breaker operation output device of the miniature circuit breaker with position state detection function and triggers the control unit to stop the motor when the closing or breaking operation of the first miniature circuit breaker reaches the specified position.

Dependent claims

A miniature circuit breaker with short-circuit self-locking function, characterized in that, which comprises:

a first miniature circuit breaker and a miniature circuit breaker operation output device, wherein,
the first miniature circuit breaker is located on a power line for generating a breaking action when a short-circuit fault occurs;
the miniature circuit breaker operation output device comprises:
a casing, in the casing, there are:
a motor for outputting a torque;
an action unit for obtaining the torque outputted by the motor and transferring the obtained torque to a closing action or the breaking action of the first miniature circuit breaker;
a control unit for controlling a rotation and stop of the motor;
and
a short-circuit protection linkage unit, wherein when the first miniature circuit breaker generates the breaking action due to the short-circuit fault, the short-circuit protection linkage unit sends an action signal to the control unit for the control unit stopping the motor after the short-circuit of the first miniature circuit breaker.
