Abstract

The invention discloses an on-site treatment device for micro wave content standard exceeding of an SF6 mutual inductor. A first valve is connected with a mutual inductor and is connected with a second valve, a third valve and a ninth valve respectively; the second valve is connected with a first gas tank; the third valve is connected with a first storage tank; the first storage tank is connectedwith a fourth valve; the fourth valve is connected with a drying tank; the drying tank is connected with a fifth valve; the fifth valve is connected with the gas inlet end of a compressor; the gas outlet end of the compressor is connected with a sixth valve; the sixth valve is connected with a seventh valve and a second storage tank; the seventh valve is connected with the gas inlet end of a vacuum pump; the gas outlet end of the vacuum pump communicates with the atmosphere; a second pressure gauge for detecting the pressure of a section between the seventh valve and the vacuum pump is arranged between the seventh valve and the vacuum pump; the second storage tank is connected with an eighth valve; the eighth valve is connected with the ninth valve and a tenth valve respectively; and the tenth valve is connected with a second gas tank. An SF6 gas in the mutual inductor can be dried without power off, and the device is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to electrical equipment SF 6 The technical field of drying treatment, in particular to a kind of SF 6 A device and method for on-site treatment of excessive water content in a transformer. Background technique [0002] SF 6 Gas insulated transformers are widely used because of their superior electrical properties. With the SF 6 With the increasing application of transformers in the power grid, the defects of excessive water content in transformers and excessive growth are on the rise. Once the inside of transformers gets wet, the electric strength will drop significantly, which will seriously affect the safe operation of equipment. SF has been discovered in recent years 6 The humidity content of the transformer generally exceeds the standard. During the operation, the excessive humidity exists and the SF 6 The risk of highly corrosive acidic substances produced by the decomposition reaction will seriously affect the performan...
