Intelligent adjustment system for metal-enclosed middle-arrangement switchgear of substation and adjustment method of intelligent adjustment system

Abstract

The invention relates to an intelligent adjustment system for a metal-enclosed middle-arrangement switchgear of a substation and an adjustment method of the intelligent adjustment system. The intelligent adjustment system comprises a main machine device, an input pipe and an output pipe, the main machine device comprises a box body and a temperature adjustment device and a humidity adjustment device arranged in the box body, the box body is provided with an air input opening and an air output opening, the air input opening is connected with the air output end of the metal-enclosed middle-arrangement switchgear through the input pipe, and the air output opening is connected with the air input end of the metal-enclosed middle-arrangement switchgear through the output pipe. The intelligent adjustment system has the functions of removing moisture, adjusting the temperature and preventing electric equipment from getting dirty, and wet and hot air in the switchgear is sucked through a sealed pipe, so that moisture is removed, the temperature is controlled and dirt in the air in the switchgear is removed, and safety and reliability of operation of the power grid are really improved.

Description

technical field [0001] The invention relates to the technical field of switchgear dehumidification, in particular to an intelligent adjustment system and an adjustment method for an armored central switchgear in a substation. Background technique [0002] The armored central switchgear of the substation belongs to the high-voltage power distribution device. The cabinet is composed of bus bars, connecting bars, trolleys, circuit breakers, knife switches and control protection devices, and is divided into various electrical compartments by steel plates and insulating parts. It is an important part of substations and power plants for collecting and distributing electric energy, detecting and automatically removing faults, etc. The currently used armored central switchgear has compact design, small distance between phases and the ground, high requirements for insulation and heat dissipation of each component, insulation, moisture resistance, dust prevention and cooling have not ...

AI Technical Summary

Problems solved by technology

The currently used armored central switchgear has compact design, small distance between phases and the ground, high requirements for insulation and heat dissipation of each component, insulation, moisture resistance, dust prevention and cooling have not been fundamentally solved, and armored central switchgear exists. The following problems: 1. Actual situations such as short circuit, grounding or discharge flashover in the armored central switch cabinet occur from time to time, and have developed to the extent of comprehensive replacement of insulating parts in the cabinet. The humidity has directly endangered the safe operation of electrical equipment.

2. The operating environment temperature of the protection, measurement and control and other electronic equipment in the armored central switch cabinet is too high, the local heat dissipation of the busbar connection and the switch contact, and the elastic change of the spring overheating (overcooling) of the operating mechanism cause contact pressure. High temperature has also directly endangered the safe operation of electrical equipment

When a short-circuit fault occurs in the cabinet, the accompanying huge energy release will be released through the ventilation of the switch room and the leakage through the explosion-proof window, directly endangering the operating equipment or staff outside the window
