Embodiment Construction

[0022] figure 1 Schematic diagram of the remote control circuit breaker manual closing for this application, as shown in figure 1 As shown, the remote control circuit breaker includes a circuit breaker body 1 , a manual operating lever 2 , a spring operating mechanism 3 , a static contact 4 , a moving contact 5 and a connecting arm 51 for fixing the moving contact 5 . The circuit breaker body 1 carries other functional components of the circuit breaker, and integrates the components for realizing circuit breaking and the components for realizing remote control. Therefore, the remote control circuit breaker of the present application only occupies the 1P track position during installation.

[0023] The static contact 4 is fixed on the circuit breaker body 1 , and the end of the connecting arm 51 corresponding to the static contact 4 is fixed with the moving contact 5 , and the movement of the connecting arm 51 drives the moving contact 5 to move relative to the static contact ...

Abstract

The invention discloses a remote control circuit breaker. The remote control circuit breaker comprises a circuit breaker body, a manual operation rod, a spring manipulation mechanism, a fixed contact, a movable contract and a connection arm for fixing the movable contract; meanwhile, the remote control circuit breaker further comprises a driving unit and a transmission assembly, which are used for remote control. Under the coordination of the driving unit and the transmission assembly, a relative position of the movable contact and the fixed contact can be controlled to change, so that bidirectional control for performing remote switching-on and remote switching-off on the circuit breaker can be realized. Meanwhile, the remote control circuit breaker provided by the invention is additionally provided with a second micro-switch; remote switching-on and remote switching-off become invalid when manual switching-off is triggered through switching off the second micro-switch, so that the maintenance security in manual operation can be ensured.

Description

technical field [0001] The present application relates to the technical field of electrical equipment, in particular to a remote control circuit breaker. Background technique [0002] Circuit breakers, also known as air switches, are used to switch on or off load circuits. When the circuit breaker is closed, the load circuit is connected to start the load; when the circuit breaker is opened, the load circuit is broken to stop the load. For traditional circuit breakers, the opening and closing actions of the circuit breaker require manual operation. For example, when repairing the circuit or stopping the power equipment in the circuit, it is necessary to manually toggle the manual operating lever on the circuit breaker for controlling tripping and closing to make the circuit breaker complete the opening action; when the repair is completed or the circuit is started When the power equipment is working, it is necessary to manually move the manual operating lever at a short di...
