AI Technical Summary

Technical Problem

The prior art is difficult to conduct convenient sealing tests during secondary installation of substation cabinet cabins, especially under the volume and weight limitations of the cabins, which cannot effectively detect the sealing performance of the cabins.

Method used

A portable sealing test device is designed, including a pneumatic pressure induction balancing mechanism, a dual-mode stationary detection mechanism and a gas storage mechanism. The air is continuously released through the high-pressure gas tank, the pressure and leakage speed in the tank are recorded, and the sealing property is judged in combination with the dual-mode stationary detection mechanism.

Benefits of technology

It realizes the convenience and accuracy of sealing tests inside the cabin, can effectively reflect the sealing performance of the cabin, and solves the problem of difficulty in judging the sealing performance of the cabin.

Abstract

The invention belongs to the technical field of sealing performance testing, and particularly discloses a cabin sealing performance testing device of a power transformation cabinet, which comprises an air pressure induction type balance mechanism, a dual-mode static detection mechanism and a gas storage mechanism, and is characterized in that the dual-mode static detection mechanism is arranged between the air pressure induction type balance mechanism and the gas storage mechanism; the air pressure induction type balance mechanism comprises an exhaust rate adjusting assembly, an in-cabin air pressure induction assembly and a transmission assembly, the in-cabin air pressure induction assembly is arranged on the exhaust rate adjusting assembly, and the transmission assembly is arranged on the in-cabin air pressure induction assembly. The invention provides a test method for continuously releasing air into a cabin body through a high-pressure air tank, when the internal part of the cabin body reaches a stage that air intake and air exhaust are balanced, the pressure in the cabin and the air intake and exhaust speed at the moment are recorded, and the sealing performance of the cabin body is fed back under the condition of testing multiple groups of pressure-air leakage speed data.
