Ventilation window structure of substation

Abstract

The invention provides a ventilation window structure of a substation. The ventilation window structure comprises a wall body and a ventilation opening, wherein the ventilation opening is provided with a border; a shutter is arranged in the border; the part between the outer side surface of the border and the inner wall of the ventilation opening is filled with a hemp thread; a metal net is arranged at the indoor side of the shutter in the border; a dustproof net is arranged at the outer side of the metal net; a plurality of large net holes are arranged in the metal net; a plurality of small net holes are arranged in the dustproof net; fixed devices are arranged at two sides of the metal net; a release button is arranged on each fixed device and is connected with a chuck through a spring mechanism in the fixed device; clamping grooves matched with the chucks are arranged in the border corresponding to the fixed devices; and angle steel is arranged between the periphery of the indoor side of the border and the inner wall of the ventilation opening; and two wall surfaces of the angle steel are locked on the inner wall of the ventilation opening and the peripheral surface of the indoor side of the border by using expansion bolts and rivets respectively. The ventilation window structure of the substation is simple and is convenient to clean and maintain; good ventilation and exhausting are achieved; and the dust is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a substation ventilation window structure. Background technique [0002] Substation, a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. The main equipment of substations are switches and transformers. According to the size, the small ones are called substations. A substation is larger than a substation. Substations are generally step-down substations with voltage levels below 110kV; substations include "boost and step-down" substations of various voltage levels. Because there are continuously working switches and transformers installed in the substation, the temperature in the substation machine room is relatively h...

AI Technical Summary

Problems solved by technology

Because there are continuously working switches and transformers installed in the substation, the temperature in the substation machine room is relatively high, so the cooling of the machine room is particularly important; the existing substations adopt the design method of ventilation windows fixed on the wall as the ventilation opening, this kind of The ventilation window has several ventilation holes, the ventilation effect is good, but the dustproof effect is not very ideal, and it is not easy to clean
