On-site rapid detection device for dissolved acetylene gas content in oil

Abstract

The invention provides an on-site rapid detection device for dissolved acetylene gas content in oil. The device comprises a controller, a formation testing and degassing device, a micro pressurized air pump, a gas detection module and a power supply; an output end of the micro pressurized air pump is connected with an air inlet of the formation testing and degassing device through a first gas circuit; an air outlet of the formation testing and degassing device is connected with an air inlet of the gas detection module through a second gas circuit; a pressure gage is installed on the first gascircuit; a pressure maintaining valve, a flow maintaining valve, an electronic flowmeter and a solenoid control valve are installed on the second gas circuit; an one-way valve is arranged on an air outlet of the air detection module; the controller is electrically connected with the pressure gage, the pressure maintaining valve, the flow maintaining valve, the electronic flowmeter, the solenoid control valve and the one-way valve respectively; the controller is connected with the power supply. According to the on-site rapid detection device for the dissolved acetylene gas content in the oil, on site rapid detection of the acetylene gas dissolving in the oil when oil-filled electric equipment suddenly fails can be achieved, so that the nature of a failure is rapidly determined. The on-siterapid detection device has the advantages that automatic controlling of the device is adopted in the whole detection process, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to an on-site rapid detection device for dissolved acetylene gas in oil, in particular to a special rapid detection device suitable for on-site detection of the content of dissolved acetylene gas in oil for oil-filled electrical equipment of various voltage levels. Background technique [0002] In recent years, judging the internal fault nature of oil-filled electrical equipment by detecting the dissolved gas content in oil during operation has become an important means to ensure the operation safety of oil-filled electrical equipment, and detecting the dissolved acetylene gas content in oil is the key to judging oil-filled electrical equipment. An important technical indicator of whether there is a serious discharge fault. [0003] The conventional method for detecting the content of dissolved acetylene gas in oil is mainly laboratory gas chromatography detection method, that is, after the operator collects the oil sample of the ...

AI Technical Summary

Problems solved by technology

The data of the dissolved acetylene gas content in the oil obtained by the above method is accurate and reliable, but it usually takes five to six hours for each oil sample to get the test result from the transportation to the completion of the entire test operation process

Once the oil-filled electrical equipment trips due to a sudden fault, when the site needs to quickly analyze and judge the nature of the fault, this method cannot meet the needs of on-site instant judgment because it takes too long
