Zero-emission SF6 pressure balancing system

Abstract

The invention relates to the technical field of electrical engineering, and discloses a zero-emission SF6 (sulfur hexafluoride) pressure balancing system. The system comprises a primary buffer tank, wherein a differential pressure sensor is arranged at one end of the primary buffer tank; a supporting plate is arranged at one end of the buffer tank and close to the top of the differential pressuresensor; an air pump is arranged at the upper end of the supporting plate; a communicating pipe is arranged at the upper end of the air pump; a No.1 connection pipe is arranged at one end of the primary buffer tank and close to the top of the communicating pipe; a No.1 flange is mounted at one end of the No.1 connection pipe; a flow valve is arranged at one end of the No.1 flange; a No.2 flange isarranged at one end of the flow valve; a No.2 connection pipe is arranged at one end of the No.2 flange. The zero-emission SF6 pressure balancing system has the advantages that sulfur hexafluoride canbe recycled, environmental pollution caused by direct emission of sulfur hexafluoride to the air can be avoided; sulfur hexafluoride is prevented from leaking during transportation; the system can becontrolled at different positions.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a zero-emission SF6 pressure balance system. Background technique [0002] Sulfur hexafluoride is currently used in electrical engineering, semiconductor processing, filling gas in the purification process of magnesium, preparation of sound insulation materials, leak detection, silent propulsion of torpedoes, etc. Its basic physical and chemical properties are revealed during gas discharge Different characteristics, in the normal environment, sulfur hexafluoride gas has strong chemical inertness, non-toxic, non-flammable, non-explosive and has excellent thermal stability, does not decompose when the temperature is lower than 500 degrees Celsius, is normal It is because of these properties that sulfur hexafluoride has been used in electrical engineering. [0003] Sulfur hexafluoride insulation has great advantages over oil insulation. Oil insulation may cause fire ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a zero-emission SF6 pressure balance system, which can recycle sulfur hexafluoride, avoid direct discharge of sulfur hexafluoride into the air and cause environmental pollution, and prevent hexafluoride Sulfur leaks during the transportation process, and the system can be controlled at different positions, etc., which solves the serious environmental pollution caused by the long-term accumulation of traditional sulfur hexafluoride emissions, and gas leakage is prone to occur in the process of treating sulfur hexafluoride , it is not convenient to control the processing equipment
