Circuit breaker on-line monitoring sensor and monitoring method

Abstract

The invention discloses a circuit breaker on-line monitoring sensor and a monitoring method. The circuit breaker on-line monitoring sensor comprises a mounting plate and a sensor body fixed on the right side of the top of the mounting plate; the left side of the top of the mounting plate is rotatably connected with a dustproof cover through a rotating member; fixing mechanisms are fixedly connected to the front face and the back face of the left side of the top of the mounting plate and located in the dustproof cover. According to the circuit breaker on-line monitoring sensor and the monitoring method, the fixing mechanisms are adopted, when a temperature and humidity probe does not carry out detection work, the dustproof cover is opened, the probe is placed in the fixing mechanisms, the probe is clamped and limited and fixed through a clamping plate, springs on two sides, and elastic plates, and the probe can be stored; after the probe is stored, the dustproof cover is closed; the dustproof cover is fixed through an adjusting bolt, and the probe is sealed in the dustproof cover, so that dust can be prevented from falling on the probe, and the monitoring accuracy of the probe is improved.

Description

technical field [0001] The invention relates to the technical field of monitoring sensors, in particular to a circuit breaker on-line monitoring sensor and a monitoring method. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into For high-voltage circuit breakers and low-voltage circuit breakers, the division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they It can automatically cut off the circuit in the event of serious overload, short circuit and undervoltage faults. Its function is equivalent to the combination of fuse switch...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a circuit breaker on-line monitoring sensor and monitoring method, which solves the problem that the temperature and humidity probe on the current sensor is exposed to the outside for a long time, and it and the cable cannot be monitored when the detection work is not performed. Storage, dust is easy to fall on the probe, which reduces the detection accuracy of the probe
