Abstract
The invention discloses an oil-gas reciprocal circular cooling system for an oil-insulated impulse voltage generator. The oil-gas reciprocal circular cooling system is formed by sequentially connecting an impulse voltage generator body (1), a reverse flow circulating system (2) and a nitrogen gas storage bin (3). The oil-gas reciprocal circular cooling system disclosed by the invention has the advantages of simpleness, reliability and safety. According to the oil-gas reciprocal circular cooling system, a fan or a refrigeration device does not need to be additionally arranged but transformer oil existing in the device and the nitrogen gas are subjected to interactive cooling, so that the manufacturing cost is reduced and energy sources are saved and can be repeatedly utilized. The oil-gas reciprocal circular cooling system has the characteristics of simpleness and convenience in operation, high safety coefficient, high visualization and energy economization.
Description
Technical field
The invention belongs to electric power high-temp liquid cooling technology field, be particularly useful for usining the cooling down of transformer oil as the impulse voltage generator insulating oil of 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 being overhauled timely and accurately is one of effective means of prevention power equipment generation major accident.Present two kinds of impulse voltage generators commonly used, a kind ofly using air as insulating medium, and generally this equipment volume is huge, is difficult for carrying; Another kind is usingd 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.Just problem has been arranged for usining 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, the 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 increase of test number (TN) and the time of each test, this will allow the insulation effect of transformer oil descend, and produces huge potential safety hazard.
Using in the impulse voltage generator process of the test of transformer oil as insulating medium based on above-mentioned the practical problems existed, proposed to adopt a kind of for the reciprocal circulating cooling system of oil-insulation impulse voltage generator oil gas.The present invention 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 surpasses predefined threshold value, now the oil gas pump all can start that to carry out oil gas reciprocal cooling simultaneously, can reduce the temperature of transformer oil to a good insulation state in short distance, short time.There is air pressure monitor in the nitrogen cabin simultaneously, once air pressure surpasses setting threshold, will report to the police, in order to take measures in time.So both reduce the loss brought 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.
Summary of the invention
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 object of the invention is to solve in oil-insulation impulse voltage generator process of the test the problem that makes the transformer oil temperature rising due to environment temperature height and heavy current size.
The present invention realizes by following technical proposal.
A kind of for the reciprocal circulating cooling system of oil-insulation impulse voltage generator oil gas, feature of the present invention is:
By impulse voltage generator body, circulated in countercurrent system and nitrogen storage compartment, sequentially connected and composed; Wherein:
Be respectively equipped with Marx device and real-time oil temperature display screen in impulse voltage generator, be connected to up temperature sensor, side is respectively equipped with transformer oil outlet and transformer oil entrance;
The circulated in countercurrent system is by controllable type air pump, controllable type oil pump and be connected respectively the impulse voltage generator body and the circulation enclosed sleeve pipe of nitrogen storage compartment forms;
The nitrogen storage compartment is by real-time air pressure display screen, and the nitrogen outlet be connected with circulation enclosed sleeve pipe respectively, nitrogen inlet form.
The invention has the beneficial effects as follows:
A. can pass through the temperature sensor identification, and the variation of real time monitoring temperature of oil in transformer;
B. work as temperature of oil in transformer and surpass predefined threshold value, now the reciprocal circulating cooling system of oil gas starts automatically, and starts to cool to transformer oil is reciprocal.
Further set forth content of the present invention below in conjunction with accompanying drawing and example.
