Intelligent medium-voltage magnetic field pressure non-contact potential measurement switch cabinet

Abstract

The invention discloses an intelligent medium-voltage magnetic field pressure non-contact potential measurement switch cabinet which comprises a cabinet body, a bus room, a cable room, an instrument room, an intelligent circuit breaker, a controller, a dehumidification blower fan, an electromagnetic sensor, an acoustic-optical sensor, a liquid crystal touch screen, a panoramic camera, a temperature measuring assembly, a current measuring assembly, and a potential measuring assembly. The cabinet body is internally equipped with the instrument room, a handcart room, an auxiliary engine room, the bus room and the cable room, which are arranged separately. The controller, the liquid crystal touch screen and the panoramic camera are assembled in the instrument room. The handcart room is equipped with the intelligent circuit breaker and a chassis. The outlet of the dehumidification blower fan is communicated with an air duct. The panoramic camera is arranged in a full view manner. According to the intelligent medium-voltage magnetic field pressure non-contact potential measurement switch cabinet, electromagnetic signal monitoring and acoustic-optical signal monitoring are performed on the cabinet body through the electromagnetic sensor and the acoustic-optical sensor, and intelligent environment monitoring is realized. The pressure sensor and the non-contact potentiometer cooperate with each other to monitor the mechanical characteristics of the intelligent circuit breaker, and intelligence of the whole medium-voltage switch cabinet is realized.

Description

technical field [0001] The invention relates to the technical equipment field of an intelligent medium-voltage central switchgear, in particular to an intelligent medium-voltage magnetic field pressure non-contact position measuring switchgear. Background technique [0002] With the promotion of smart grid, the market urgently needs related smart equipment, the intelligent transformation of traditional substations and the intelligent application of newly designed substations are imperative; power switchgear is one of the most commonly used equipment in the power field, its reliability, Controllability and safety will directly affect the safe operation and fault prevention of the power system; the medium voltage switchgear is a kind of switching electrical equipment in the power switchgear, the external current first enters the main control switch in the cabinet through the wire, and then enters the sub-control switch Connect with each branch; each branch needs to be equipped...

AI Technical Summary

Problems solved by technology

The intelligence of the medium voltage switchgear is firstly the intelligence of the circuit breaker and the intelligence of the switchgear; the shortcomings and deficiencies in the prior art are that usually only the intelligence of the circuit breaker is carried out, but for the overall internal environment of the switchgear, Intelligent monitoring, inspection, control, diagnosis, and early warning of the external environment of the switchgear lack effective technical means; develop intelligent medium-voltage switchgear for real-time control, monitoring, diagnosis, and inspection of the internal and external environment of the medium-voltage switchgear, and Integrate into the entire grid to ensure the safety of the overall grid operation of power generation, transmission, distribution, and consumption
