SF6 gas electronic control inflator

Abstract

The invention discloses an SF6 gas electronic control inflator, and relates to the technical field of gas measurement devices or inflating devices. The inflator comprises a housing, the housing comprises an upper end cover and a lower end cover, the upper end cover is in clamp connection with the lower end cover, and the contact position of the upper end cover and the lower end cover is provided with a waterproof sealing rubber strip. The inflator also comprises a PLC control unit, a tough screen, a proportional solenoid valve, a wireless transmission module, a power supply, temperature sensors, a humidity sensor, pressure sensors, SF6 sensors, an alarm circuit, a button circuit and a remote controller. The inflator has the characteristics of high inflating precision, safe and reliable use, and high work efficiency.

Description

technical field [0001] The invention relates to the technical field of a gas measuring device or an inflating device. Background technique [0002] The circuit breakers currently used in the power system mainly have voltage levels of 10kV, 35kV, 66kV, 110kV, 220kV, 500kV, 750kV, and 1000kV. The high-voltage circuit breaker can not only cut off and connect the no-load current and load current in the high-voltage circuit under normal conditions, but also cooperate with the protection device and the automatic device when the system fails to quickly cut off the fault current to prevent the expansion of the accident and ensure the safety of the system. safe operation. When the fault current is cut off or the operating switch is disconnected according to different operating modes, an arc will be generated. The damage caused by the arc is very serious. Its temperature is as high as thousands of degrees Celsius, which can damage the equipment in light cases, and cause explosions an...

Problems solved by technology

[0006] Problems that are prone to occur in the current gas filling operation: (1) The accuracy of gas filling and gas filling is not easy to control

Since the person who observes the pointer is not the same person who operates the knob of the pressure reducing valve of the gas cylinder, the observation and operation cannot be carried out synchronously, and the command to stop inflation will be delayed, so that the inflation is too high or too low, which affects the accuracy and even requires rework

[0007] (2) The inflatable tube freezes and bursts

[0008] (3) Missing important links in the workflow

The SF6 gas inflation process requires flushing the inflation hose 3mm before filling the equipment until the inner wall of the hose is fully dry to prevent moisture from being brought into the equipment. This step is easily forgotten in actual operation. Operation poses a safety hazard

[0009] (4) Ignoring the requirements of the working environment
