Technical field
The utility model belongs to electric power high-temp liquid cooling technology field, is particularly useful for the cooling down of the impulse voltage generator insulating oil using transformer oil as insulating medium.
Background technology
National economy and society further develop, power supply reliability has been proposed to more and more higher requirement, and the testing on-site impact of the power equipments such as GIS (comprising lightning impulse, switching impulse and fast transient overvoltage) discovering device Insulation Problems overhauling is timely and accurately one of effective means of prevention power equipment generation major accident.Two kinds of conventional impulse voltage generators now, a kind of using air as insulating medium, generally this equipment volume is huge, is difficult for carrying; Another kind is using transformer oil as insulating medium, and this equipment volume is less, and testing on-site impact is carried out at the scene that can be carried to.For just having had problem using transformer oil as insulating medium, the factors such as weather, process of the test of considering can cause oil temperature to change, and the insulating property of transformer oil change along with temperature change, General Requirements temperature of oil in transformer is controlled in 40 ℃, so good insulation effect of guarantee.And in the middle of actual tests, temperature of oil in transformer can increase and raise along with the time of the increase of test number (TN) and each test, this will allow the insulation effect of transformer oil decline, and produces huge potential safety hazard.
Based on the practical problems existing in the above-mentioned impulse voltage generator process of the test using transformer oil as insulating medium, proposed to adopt a kind of for the reciprocal circulating cooling system of oil-insulation impulse voltage generator oil gas.The utility model adopts and draws high temperature oil and form reciprocal staggered circulation temperature lowering with the nitrogen of large specific heat capacity, and do not need manual shift, as long as oil temperature exceedes predefined threshold value, now oil gas pump all can start that to carry out oil gas reciprocal cooling simultaneously, can reduce in short distance, short time the temperature of transformer oil to good insulation state.There is air pressure monitor in nitrogen cabin simultaneously, will report to the police, to take measures in time once air pressure exceedes setting threshold.So both reduce the loss bringing due to problems such as oil temperature rising insulation breakdowns, and made again test clerk be in the experimental enviroment of a safety.This system automation degree is high, easy and simple to handle, cooling-down effect is good, safety coefficient is high.
Utility model content
Because the oil-insulation effect of oil-insulation impulse voltage generator depends primarily on the height of temperature of oil in transformer, insulation effect is related to the success or not of test and the safety of testing crew.Therefore the purpose of this utility model is to solve in oil-insulation impulse voltage generator process of the test the problem that makes transformer oil temperature rising due to environment temperature height and heavy current size.
The utility model is realized by following technical proposal.
A kind of for the reciprocal circulating cooling system of oil-insulation impulse voltage generator oil gas, the utility model feature is:
By impulse voltage generator body, circulated in countercurrent system and nitrogen storage compartment, sequentially connected and composed; Wherein:
In impulse voltage generator, be respectively equipped with Marx device and real-time oil temperature display screen, be connected to up temperature sensor, side is respectively equipped with transformer oil outlet and transformer oil entrance;
Circulated in countercurrent system is by controllable type air pump, controllable type oil pump and be connected respectively impulse voltage generator body and the circulation enclosed sleeve pipe of nitrogen storage compartment forms;
Nitrogen storage compartment is by real-time air pressure display screen, and the nitrogen outlet, the nitrogen inlet that are connected with circulation enclosed sleeve pipe respectively form.
The beneficial effects of the utility model are:
A. can pass through temperature sensor identification, and the variation of real time monitoring temperature of oil in transformer;
B. when temperature of oil in transformer exceedes predefined threshold value, now the reciprocal circulating cooling system of oil gas starts automatically, and starts to cool to transformer oil is reciprocal.
Below in conjunction with accompanying drawing and example, further set forth the utility model content.
