Description
Technical Field
The invention relates to the field of electrical detection equipment, in particular to an automatic light gas taking device for a gas relay.
Background
At present, a gas relay gas taking mode needs to arrange personnel to take gas on a fault site after light gas acts, and the gas taking mode method comprises the following steps:
when the light gas alarm signal is received, workers need to be dispatched to the fault site in time to carry out gas sampling. Unscrewing an oil drain plug at the lower part of the gas collection box, opening the oil drain plug at the lower part of the gas collection box, discharging transformer oil in the box, when the oil level in the box is lowered, accumulated gas in the gas relay enters the gas collection box along the gas-guiding copper pipe under the action of body oil pressure, and when the gas-guiding pipe continuously discharges oil, a light gas signal disappears and the oil level in the gas collection box begins to rise, indicating that no accumulated gas exists in the gas relay, and tightly closing the oil drain plug;
preparing a latex tube, a medical three-way valve and an injector, wherein one end of the latex tube is connected with an exhaust plug on the upper part of the gas collecting box, the other end of the latex tube is connected with the three-way valve, and the injector is connected with the three-way valve;
opening an air release plug at the upper part of the air collection box, rotating the tee joint direction, and flushing the connecting pipeline and the injector by using a small amount of gas in the gas relay; then the direction of the tee joint is adjusted to take gas.
The prior art has defects or shortcomings:
the working requires operators to correctly master and implement the sampling operation method, otherwise the sampling accuracy is affected, and meanwhile, the sampling operation method needs cooperation of multiple persons, records the gas amount manually, observes the color of the gas and determines whether the experiment is combustible, so that the sampling operation method has the characteristic of low accuracy.
When the gas protection signal acts, the transformer is immediately checked to check whether the gas is combustible or not due to air accumulation, oil level reduction, gas color observation and test, so that serious accidents are avoided.
If the gas is combustible or the analysis result of the gas dissolved in the oil is abnormal, comprehensive judgment is carried out to determine whether the transformer is shut down.
After manual gas extraction, gas loss may occur in various links such as gas storage, transportation, laboratory analysis and the like, so that an analysis result is influenced, wrong judgment is caused, and even safe operation of the transformer is endangered.
If the analysis result is air after the manual gas taking, the gas relay sends out a false alarm signal, and manpower and material resources are wasted.
