Intelligent pressure relief equipment for box-type substation

Abstract

The invention provides intelligent pressure relief equipment for a box-type substation, and relates to the technical field of box-type substations. The intelligent pressure relief equipment for the box-type substation comprises a conventional pressure relief assembly, a pressure relief pipe is arranged in the conventional pressure relief assembly, a fixing rod is welded to the top of the interior of the pressure relief pipe, and the outer wall of the fixing rod is slidably connected with a dust blocking plate. And when the air pressure in the box body is continuously increased, the heat dissipation net can deflect rightwards in the heat dissipation window, so that the effect of automatically releasing the pressure to avoid the explosion accident of the transformer substation when the air pressure in the box-type transformer substation is too high is achieved. And when the air pressure in the box body gradually recovers, a time delay effect can be achieved when hydraulic oil in the second hydraulic groove enters the first hydraulic groove, so that the heat dissipation net is slowly reset to the interior of the heat dissipation window, and the situation that high pressure occurs in the box-type substation again due to the fact that the pressure relief channel is rapidly closed during high-pressure pressure relief is avoided.

Description

technical field [0001] The invention relates to the technical field of box-type substations, in particular to an intelligent pressure relief device for box-type substations. Background technique [0002] Box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. At present, the box-type substation on the market lacks a pressure relief mechanism. The air pressure inside the transformer box is too high, which will cause damage to other spacers in the box or bursting of the box, and the safety performance is poor. [0003] In order to solve the above problems, we provide an intelligent pressure relief device for box-type substations, which can automatically release pressure when the internal pressure of box-type substations is too high to avoid explosion accidents in substations, good waterproof and dustproof, and avoid high-pressure pressure relief At this time, the pressure relief channel is quickly closed, r...
