Abstract

The invention relates to an electrical equipment leakage online monitoring method and device, and a computer readable storage medium. The electrical equipment leakage online monitoring method comprises steps that the electrical equipment leakage online monitoring device is connected with electrical equipment, and gas to be detected in the electrical equipment is guided into a measuring gas chamber of the electrical equipment leakage online monitoring device; the electrical equipment leakage online monitoring device obtains a first resonant frequency of a first quartz crystal sensor in a reference gas environment in a reference gas chamber through an oscillating circuit, and obtains a second resonant frequency of a second quartz crystal sensor in a to-be-measured gas environment in a measuring gas chamber in real time through the oscillating circuit, the first quartz crystal sensor and the second quartz crystal sensor have the same parameters; and the electrical equipment leakage online monitoring device determines whether the electrical equipment leaks or not according to a difference value between the first resonant frequency and the second resonant frequency. The device is advantaged in that whether the insulating gas in the electrical equipment leaks or not can be monitored in real time, the detection speed is high, and sensitivity is high.

Description

technical field [0001] The disclosure relates to the field of electrical equipment detection, in particular to a method and device for on-line monitoring of electrical equipment leakage, and a computer-readable storage medium. Background technique [0002] Gas-insulated equipment is one of the irreplaceable key power transmission and transformation equipment for modern power grids due to its advantages of compact structure, little influence from environmental factors, and high operational safety and reliability. Density is an important physical parameter of insulating gas. It is often used as an important technical index to test whether electrical equipment is leaking. The decrease of density will reduce the electrical performance of insulating gas, which will endanger the safe operation of equipment. Therefore, in order to ensure the safe and stable operation of gas-insulated equipment, the monitoring of gas density in the equipment is particularly important. Contents of ...
