Control system for improving operation environment of substation equipment

Abstract

The invention discloses a control system for improving the operation environment of substation equipment, comprising an air intake, an intelligent ventilation regulator, an air outlet, an SF6 (sulfur hexafluoride) overflow port, a temperature sensor and an intelligent control unit, wherein the air inlet and the air outlet are arranged on the wall surface of the same side, the air outlet is higher than the air inlet, and the SF6 overflow port is arranged on the bottom of the wall surface at one side close to the air outlet. According to the control system, air flows in an indoor substation, an underground substation and other similar sealed space environments are effectively organized, mixed flow and turbulence generated by the ventilation of the common fan can be avoided, the natural convection form for the air flow to cover a heat source body through the lower part of a heating element from bottom to top can be furthest kept, and the aerated cooling efficiency of the surface of the heat source body is greatly improved.

Description

technical field [0001] The invention relates to a control system for improving the operating environment of substation equipment, in particular to a control system for improving the equipment operating environment in indoor substations, underground substations and other similar closed space environments with compact arrangement of equipment. Background technique [0002] With the rapid development of the national economy and power grid, there are more and more substations of various voltage levels. In order to save precious land resources and reduce environmental problems such as noise and radiation, these power transformation and distribution facilities are increasingly designed as compact indoor arrangements or placed underground. The closed environment makes the electrical equipment of these substations The operating conditions are very harsh, and necessary ventilation and cooling systems need to be installed. Conventional ventilation and cooling systems are realized by ...

Problems solved by technology

Due to the lack of effective organization of the air flow, this method not only has low ventilation and cooling efficiency and poor energy efficiency, but also generates a large number of environmental problems: First, a large amount of outdoor air will bring dust and salt or acid substances floating in the air into the air. In the equipment room, after they adhere to the surface of the equipment or insulator to form dirt, they will not only corrode the equipment, but also form a discharge channel, causing safety accidents such as creepage and pollution flashover; moreover, under the condition of light load of equipment or hot climate, a large number of When hot and humid air from outside enters the room, especially in the underground substation and distribution room, it is easy to form condensation on the surface of walls, equipment or insulators, which can cause insulation failures such as discharge and flashover. energy consumption; finally, due to the additional noise brought by the large air volume fan, the already serious problem of noise nuisance is even worse

[0003] To sum up, the existing ventilation measures lead to high internal ambient temperature of the substation (distribution) station, serious dust accumulation on the surface of the equipment, and increased energy consumption of ventilation and air conditioning equipment, especially in the peak summer season, due to the indoor environment Temperature affects the safe and stable operation of substations, exacerbating the contradiction between power supply and demand
