Blocking device

Abstract

The invention relates to a blocking device. The blocking device includes a gasket, a base and a cover. The gasket is used for connecting with the device to be blocked, and the gasket is provided with a first through hole, and the first through hole is used for communicating with the leakage hole of the device to be blocked. The base is connected with the gasket, the base is provided with a second through hole, and the second through hole communicates with the first through hole. The cover is detachably connected to the base, and the cover is used to block the second through hole. Through the pressure relief function of the first through hole and the second through hole, the above-mentioned blocking device makes the whole blocking process without power failure, and there will be no pressure impact on the glue between the gasket and the equipment to be blocked during the blocking process. , so that the glue can be solidified stably, improving the sealing quality and stability between the gasket and the equipment to be sealed, and avoiding repeated leakage.

Description

technical field [0001] The invention relates to the technical field of electric equipment maintenance, in particular to a blocking device. Background technique [0002] GIS (Gas Insulated Switchgear, gas-insulated metal-enclosed switch) equipment consists of circuit breakers, isolating switches, grounding switches, transformers, lightning arresters, busbars, connectors and outlet terminals, etc., all of which are enclosed in metal grounding enclosures , the inside of the shell is filled with a certain pressure of SF 6 Insulating gas, so it is also called SF 6 Fully enclosed combined electrical appliances. GIS equipment has been widely used all over the world due to its small footprint, high reliability, and flexible configuration. [0003] However, GIS equipment often has air leakage due to the material defects of its manufacturing materials. Since the material defects of electrical equipment cannot be dealt with, the current treatment methods for electrical equipment ai...

AI Technical Summary

Problems solved by technology

Since the material defects of electrical equipment cannot be dealt with, the current treatment methods for electrical equipment air leakage are mainly divided into power-off treatment and non-power-off treatment, but no matter which method is currently used, it is impossible to use the most efficient, low-risk and most The economical way to trap leaks

For example, power outage treatment will lead to problems such as power outage loss load, disintegration maintenance and construction risks, etc., not only cannot completely cure the air leakage problem of the equipment, but also cause various power outages and construction risks, consume manpower and material resources of the enterprise, and cause equipment loss and other problems

However, the plugging effect of non-stop treatment is not good. Taking the method of directly using sealant to plug leaks as an example, although it can alleviate the leakage of SF6 gas to a certain extent in a short time, it is very difficult to plug leaks under pressure. 6 The pressure of gas accumulation increases, and the sealant will bulge after plugging, resulting in large-area leakage again
