Abstract

The invention belongs to the field of electrical sealing performance testing, and particularly relates to an SF6 circuit breaker rubber sealing ring airtightness testing device. Comprising an airtight test box, a water tank, a fixed support and a gas recovery system. The SF6 circuit breaker aged rubber sealing ring air tightness test and gas recovery device can perform air tightness test on the aged rubber sealing ring, accurately judge whether the sealing element is invalid or not, and recover SF6 gas for test to avoid leakage of the SF6 gas. The sealing reliability can be effectively improved, safety accidents caused by SF6 density reduction due to gas leakage are reduced, the purposes of high SF6 recovery safety and prevention of leakage during SF6 recovery are achieved, and the operation stability of an electric power system is improved.

Description

technical field [0001] The invention belongs to the field of electrical sealing performance testing and discloses a SF 6 Circuit breaker rubber sealing ring air tightness test device. Background technique [0002] As a class of organic polymer compounds, rubber has high volume elasticity and low shape elasticity, as well as excellent mechanical strength, chemical stability and weather resistance, and is an ideal sealing material. [0003] O-shaped and rectangular rubber sealing rings are the most commonly used sealing forms, and are widely used in various oil-filled and inflated electrical equipment in power grids and power plants, such as high-voltage switch seals, transformer oil seals (diaphragms, capsules, flanges, etc.), electrolytic Power grid equipment such as capacitor seals, mechanism box seals, and terminal box seals, as well as hydraulic systems, rotating systems, and fuel systems in power plants. [0004] According to statistics, as of 2016, among the critical ...
