Description
Affiliated technical field
The utility model relates to a kind of high-voltage power capacitor, is mainly used in to electric power system quadergy is provided.
Background technology
The application of capacitor is very widely in the electric power system, all can be applied to from the power high voltage network to user side, is indispensable equipment in the system.In the prior art, composite type electric power capacitor is divided into oil immersion and gas-insulated two big classes, oil capacitor brings a lot of problems because there is transformer oil will have problems such as leakage, deterioration of oil to operation and maintenance, has not become application trend of electric power system so there is oiling.Existing gas-insulated composite type electric power capacitor majority is not considered heat dissipation problem, for example Chinese patent application number is 99234596 patent, it can solve the firing and explosion prevention problem, but owing to do not consider gas is the non-conductor of heat, make the performance degradation of capacitor in actual applications because of poor heat radiation, be difficult to apply.Number of patent application is that 01212594.6 patent has proposed the new method that addresses this problem, promptly adopt the mode of heat pipe heat radiation that heat transferred is gone out between the capacitor unit in casing and casing, but it is the technology of the common heat pipe heat radiation of employing, be that heat absorbing end (evaporation ends) is following, radiating end (condensation end) is last, be a forthright rather than loop, this heat pipe be the heat transferred of casing inner capacitor unit can be gone out.But it has a drawback, always having under some normal temperature incondensible gas such as oxygen and hydrogen etc. exactly in heat pipe generates, and As time goes on can get more and more, these gases can accumulate in radiating end (condensation end) in general heat pipe, when collection was many more more, heat pipe had just reduced the efficient of its heat exchange gradually, final even complete failure, this definitely is potential safety hazard to gas-insulated composite type electric power capacitor, solves badly, will go wrong.In a word, the heat radiation of existing gas-insulated composite type electric power capacitor more or less all is to have some problems, and these problems do not solve will influence its application.
Summary of the invention
The purpose of this utility model provides a kind of novel gas-insulated composite type electric power capacitor, when making capacitor reach fire-proof and explosion-proof, adopts this better heat-conducting mode of separate heat pipe again, and the performance of capacitor is improved.
The said gas-insulated composite type of the utility model electric power capacitor, the capacitor unit 2 that comprises assembling in the casing 1, gassy in the casing 1 of sealing, between casing 1 and the capacitor unit 2 heat exchanger 3 is housed, heat exchanger 3 closes separate heat pipe 3 with the loop for evaporation section and the separated formation of condensation segment, the condensation segment of separate heat pipe 3 closely is connected with casing 1, and its evaporation section closely is connected with capacitor unit 2.
Casing 1 is the structure of closed, and is insulation gas filled in the casing 1, comprises sulphur hexafluoride, nitrogen, dry air etc., slight pressure in the casing 1 is higher than outside the casing, thereby guarantee reasonable insulation property,, can all use indoor and outdoor because casing 1 is airtight.
Heat exchanger 3 between casing 1 and the capacitor unit 2 is the separated separate heat pipe 3 of evaporation section and condensation segment.Heat pipe is known one of the most effective heat transfer element, and it can transmit a large amount of heats at a distance by its very little sectional area and need not additionaling power, and its thermal conductivity is considerably beyond any known metal.Heat pipe is airtight structure, the certain vacuum degree of inner maintenance, and be filled with certain liquid, and an end heated liquid can be vaporized in the pipe, becomes liquid again to other end cooling back gas, moves in circles, and the heat pipe two ends are almost not have the temperature difference.The Heat Transfer of Heat Pipe on Heat Pipe ability is surprising, and its limit of the heat pipe of 4 millimeters internal diameters is transmitted energy can surpass 5 kilowatts, and the heat on the capacitor unit can be delivered on casing and the radiator very soon.The temperature of capacitor unit should be close with the temperature on the casing radiator, and this also can reduce the temperature rise of whole gas-insulated composite type electric power capacitor.
Its evaporation section of common heat pipe and condensation segment are that no compartment of terrain links together substantially, be independent structures one by one, be used in the gas-insulated composite type electric power capacitor, because wherein the gas that can not condense of Chan Shenging can block the radiating end of heat pipe, cause the efficient of heat exchange to reduce even inefficacy, employing evaporation section and the separated formation of condensation segment are closed the separate heat pipe 3 with the loop, just can address this problem better, this be because close and the loop do not have the dead band, incoagulable gas just cause vacuum degree variation and can block via, substantially can heat exchanging constitute influence.
Sometimes it is not enough only depending on casing 1 to dispel the heat, so also radiator 4 will be installed outside casing 1, it closely is connected with casing 1, can better heat be distributed.In this case, the condensation segment of separate heat pipe 3 closely has been connected together respectively with casing 1 and casing 1 radiator 4 outward.
It is not enough only having only one group of separate heat pipe 3, because the unit of capacitor 2 may be more, and one group radiating effect is also not so good, generally, adopts multicomponent from formula heat pipe 3 heat transferred to be gone out.
The utility model is compared with existing technology, owing to adopted evaporation section and the separated separate heat pipe 3 of condensation segment, can solve the integrity problem of general heat pipe heat exchange well, strengthened the fail safe of this capacitor greatly, and needn't be more termly more heat exchanger tube guarantee fail safe, because heat transfer efficiency improves, and can reduce the temperature rise of gas-insulated composite type electric power capacitor significantly.This capacitor is no oiling structure, meets power system development trend; Adopt the heat pipe 3 of separate type, increased the contact area with casing 1 and capacitor unit 2, can save the required fee of material of heat pipe again, improved heat exchange efficiency.
