Abstract
The invention provides an intelligent SF6 (sulfur hexafluoride) gas inflation module for electrical equipment. The SF6 gas inflation module comprises an SF6 gas tank, a first solenoid valve, a first pressure detector, a first control, a second solenoid valve, a second pressure detector, a second control, a constant temperature heater, a fourway pipe, a vacuum pump, a third control valve and a fourth control valve. When the pressure value of SF6 gas in the SF6 electrical equipment received by the first control is lower than a first preset pressure threshold value, the SF6 electrical equipment is inflated through an gas inflation pipeline; and when the pressure value of SF gas in the SF6 gas tank received by the second control is lower than a second preset pressure threshold value, gas is added into the SF6 gas tank through a gas-adding pipeline; the constant temperature heater is used to perform constant temperature heating during gas inflation; and the second preset pressure threshold value is larger than the first preset pressure threshold value, and the gas inflation pipeline and the gas-adding pipeline are not connected at he same time at any moment. The intelligent SF6 gas inflation module can automatically perform gas inflation on the SF6 electrical equipment.
