Abstract

The invention discloses a remote control circuit breaker opening mechanism. The mechanism comprises a main body and a remote controller. The main body comprises a top head, a driving unit, a control unit and a wireless signal receiver. After a control button of the remote controller is pressed, a switching-off signal can be sent to the wireless signal receiver in a wireless mode through the wireless signal transmitter. And the control unit can control the driving unit to drive the top head to move after the wireless signal receiver receives the opening signal so as to push an emergency openingtripping button of the circuit breaker. According to the remote control circuit breaker opening mechanism, the remote controller is arranged, the wireless signal transmitter and the wireless signal receiver are arranged, wireless signal transmission is conducted between the remote controller and the controller through the wireless signal transmitter and the wireless signal receiver, an operator can execute operation after retreating to a safe position according to needs, due to wireless transmission, limitation on the operator is small, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, and more specifically, relates to a remote control circuit breaker opening mechanism. Background technique [0002] In the 10kV power distribution room, the most commonly used switchgear is: KYN28 armored removable switchgear. The vacuum circuit breaker of this equipment has the function of remote control opening and closing, which can realize remote automatic opening and closing. However, with the increase in the number of openings and the interference of some external environmental factors, the opening motor coil of the vacuum circuit breaker will often fail, resulting in failure to automatically open and close. After this kind of situation occurs, the circuit breaker is often still in a charged state. At this time, the circuit breaker can only be repaired or replaced after the charged state is released by manually pressing the "emergency opening and tripping button". But there will b...
