A quick connector for on-site detection of sulfur hexafluoride

Abstract

The invention discloses a quick connector for on-site detection of sulfur hexafluoride, comprising: a female connector of a check valve, the end of which is fixed on the air outlet of the electrical equipment, and the female connector of the check valve can be snapped into the U In the type card slot, the inside of the check valve female joint is provided with a valve assembly; and, the check valve male joint includes an outer shell and a pressing assembly arranged in the outer shell; when the check valve male joint faces When the female joint of the check valve moves linearly, the pressing assembly can squeeze the valve assembly, and make the female joint of the check valve communicate with the inside of the male joint of the check valve; the outer shell A trachea joint communicating with the inside is also provided on the outer wall of the tank. The invention can be operated by one person and one hand, no need to use other tools for stabilization, the connection is accurate and reliable, and the gas sampling joint can be installed in place safely, quickly and accurately for test work.

Description

technical field [0001] The invention relates to the technical field of electrical equipment test and maintenance, in particular to a quick connector for on-site detection of sulfur hexafluoride. Background technique [0002] Sulfur hexafluoride (SF6) has good insulating properties and arc extinguishing properties, so it is widely used in power systems. According to statistics, in addition to some transformers in electrical equipment, SF6 electrical equipment is gradually replacing insulating oil electrical equipment and has become the mainstream equipment of high-voltage electrical equipment in my country's power grid system, such as: circuit breakers, CT, PT, knife switches, high-voltage transformers, cables, GIS Stand and wait. In my country, more than half of the electrical equipment with a voltage level of 220kV is insulated with SF6 gas; nearly 100% of the equipment with a voltage level of 330kV is insulated with SF6 gas; all equipment with a voltage level of 550kV and ...

AI Technical Summary

Problems solved by technology

[0005] 1. The installation process requires the cooperation of two people. If the cooperation is not proper, the detection joint and the equipment joint cannot be accurately connected, which will cause SF6 gas leakage;

[0006] 2. When working in the gap between combined electrical appliances in a narrow space, it is difficult to use forceps to tightly fix the joints, which increases the difficulty of personnel operations;

[0007] 3. When carrying out the work at high altitude, it is difficult for two people to cooperate with the operation, there is a safety risk of falling from high altitude, and the physical fitness requirements of the on-site staff are too high
