Embodiment Construction

[0020] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0021] Such as figure 1 As shown, a circuit breaker position state signal feedback device is mainly composed of a signal acquisition module 2, a signal feedback module 3 and a controller electronic module 4, and the signal feedback module 3 is electrically connected to the signal acquisition module 2 and the controller electronic module 4 at the same time , so that the three-position state signal of the circuit breaker collected by the signal acquisition module 2 is transmitted to the signal feedback module 3 , and then transmitted to the controller electronic module 4 through the signal feedback module 3 .

[0022] Such as figure 1 As shown, the signal feedback module 3, the controller electronic module 4 and the signal acquisition module 2 are respectively installed on the drawer seat top cover 1 or the circuit breaker body (not shown in the figure). ...

Abstract

The invention discloses a circuit breaker position state signal feedback device. The device comprises a signal acquisition module and a signal feedback module, wherein the signal feedback module is electrically connected with the signal acquisition module and a controller electronic module at the same time, so circuit breaker three-position state signals acquired by the signal acquisition module are transmitted to the signal feedback module; and the signals are transmitted to the controller electronic module through the signal feedback module. The device is advantaged in that three-position state signals, collected by the signal collection module, of the circuit breaker are fed back to the controller electronic module through the signal feedback device, so the three-position state signalsare transmitted to the client through the controller via digital signals, and a client is not limited by regions.

Description

technical field [0001] The invention belongs to the field of circuit breakers, in particular to a circuit breaker position state signal feedback device. Background technique [0002] A draw-out circuit breaker is a circuit breaker that can disconnect the power supply. Put the circuit breaker body in the drawer seat, it becomes a drawer type circuit breaker. The purpose of designing the drawer type circuit breaker: 1. It is convenient to replace the circuit breaker. When the operating circuit breaker fails and is damaged, the spare circuit breaker can be replaced quickly. Just shake the damaged circuit breaker out of the drawer seat and install it. A new circuit breaker is enough to reduce the power outage time; 2. It can be used as an isolator. When the circuit or equipment needs to be repaired, for the sake of safety isolation, the circuit breaker body is shaken out, and the circuit is broken and isolated. [0003] In order to meet the intelligent needs of the power suppl...
