Abstract

The invention relates to an SF6 air inflation device. The SF6 automatic air inflation device comprises an air inflation pipeline connected between an SF6 air bottle and an air chamber of an electric device, a sensor detector for detecting environmental parameters, a control actuator and an automatic control device, wherein the control actuator is arranged on the air inflation pipeline between the SF6 air bottle and the air chamber of the electric device; the automatic control device is connected with the sensor detector in a communication mode and is connected with and controls the control actuator; and the automatic control device, the sensor detector and the control actuator jointly form a closed ring control system. The air inflation device disclosed by the invention can be used for automatically detecting the air pressure in the air chamber of the electric device and feeds the air pressure back to the automatic control device to achieve automatic real-time air inflation and air supplementation under the unattended condition so as to ensure that the pressure of the air chamber meets the set requirements after air inflation is finished, has high control precision and high air inflation efficiency, and is labor-saving; the air inflation device is used for controlling the turnon and turnoff and the flow rate of an air path during air inflation, can ensure stable air inflation, and is intelligent and flexible, convenient to operate, and stable, reliable and safe in use.

Description

technical field [0001] The invention relates to an auxiliary inflating device and method for electrical equipment, in particular to an SF6 automatic inflating device and an automatic inflating method thereof. Background technique [0002] SF6 is widely used in electrical equipment such as circuit breakers, high-voltage transformers, and gas-enclosed combined capacitors due to its excellent insulation and arc-extinguishing properties. However, at present, the filling of SF6 gas in such equipment is mainly done manually, which is wasteful. Manpower, low work efficiency, inaccurate control of inflation pressure and other issues. [0003] The SF6 automatic inflation device in the prior art, such as the intelligent SF6 inflation device for electrical equipment disclosed in the invention patent with the publication number CN103697324A, realizes the inflation control through the rated pressure locking alarm device. The rated pressure locking alarm device mainly includes electric co...
