Intelligent detection and early warning system for contact engagement fault of draw-out type circuit breaker

Abstract

The invention relates to the technical field of circuit breaker detection, and discloses an intelligent detection and early warning system for contact engagement fault of a draw-out type circuit breaker, which comprises a circuit breaker cabinet body, an intelligent terminal and a camera. The interior of the circuit breaker cabinet body is slidably connected with a circuit breaker handcart; one side of the circuit breaker handcart is fixedly connected with a contact arm; one end of the contact arm is fixedly connected with a moving contact; the interior of the circuit breaker cabinet body is fixedly connected with a contact box; and the interior of the contact box is fixedly connected with a static contact. Compared with an infrared six-point temperature measurement method, the method is more direct, more accurate and more timely, is wider in application, plays a role in an operation stage, also plays a role in a factory production debugging stage and an on-site installation debugging stage of the switch cabinet, greatly shortens the debugging time, and improves the working efficiency. The system can be widely applied to draw-out type switch cabinets and circuit breakers with contact between moving and static contacts, switching stations and transformer substations with the voltage class from 0.4 KV to 35 KV, and the like.

Description

technical field [0001] The invention relates to the field of circuit breaker detection, in particular to an intelligent detection and early warning system for contact engagement faults of a withdrawable circuit breaker. Background technique [0002] At present, whether it is in the manufacture and debugging of circuit breakers or in live operating conditions, the detection of the engagement of dynamic and static contacts cannot be called direct (intuitive, direct, real-time and real-time), and most of them use indirect methods (with the help of intermediate tools). or imprint observation) to judge; for the circuit breakers that are running with electricity, almost most of them cannot be directly detected or detected under all working conditions, and there are still many detection blind spots. [0003] In general, in the factory manufacturing process and on-site installation and debugging process, the most practical method is to judge the engagement state of the contacts by t...

Problems solved by technology

[0010] Aiming at the deficiencies of the prior art, the present invention provides an intelligent detection and early warning system for contact engagement faults of a withdrawable circuit breaker, which has the advantages of implementing detection and alarm, and solves the problem that there is no way to directly observe the engagement state of the static and dynamic contacts during the debugging stage. The problem that detection and alarm cannot be implemented
