Abstract
The technical scheme of the utility model provides an electric protecting device utilizing a full-range air-insulated protecting fuse for an American box transformer, which comprises an American box transformer high-voltage side panel and a fuse baseplate arranged on the American box transformer high-voltage side panel. The electric protecting device utilizing the full-range air-insulated protecting fuse for the American box transformer is characterized in that one end of a ceramic insulator is fixed on the fuse baseplate, a fuse clamper and a fuse clip are arranged on the other end of the ceramic insulator, and the full-range air-insulated protecting fuse is fixed on the fuse clip and clamped tightly by the fuse clamper. The electric protecting device utilizing the full-range air-insulated protecting fuse for the American box transformer has the advantages that temperature rising performance is greatly improved, insulating property is fully guaranteed, pollution and leakage to transformer oil caused by a full-range oil-immersed protecting fuse when a sleeve leaks or the fuse bursts can be fully avoided, and the problem that the full-range oil-immersed protecting fuse requires point contacting and a contact is easy to be heated up and partially burnt after serving for a long time is solved.
Description
Technical field
The utility model relates to a kind of American case power transformation of 35kV series of combination gas shiled equipment that adopts air insulation gamut protection fuse protective device.
Background technology
Wind power generation, photovoltaic generation are as the develop rapidly of a kind of clean reproducible energy industry.Characteristics such as compact conformation, good airproof performance, volume are little because American case becomes, convenient transportation, honourable electric field investment, always all favor use American case to become in booster system.American transformer mainly contains: high-pressure section, step-up transformer, low-pressure section are formed, and electic protection mainly is made up of electric elements such as circuit breaker and oil immersed type Whole Scope Current Limiting Fuse.Through the understanding to the American case change of wind power generation 35kv series operation conditions in these several years, accident analysis and summary, the step-up transformer during American case becomes moves in electricity generation system, and the accident that causes is at most that the oil immersed type gamut is inserted fuse.The oil immersed type gamut of domestic production is at present inserted fuse, can produce the normally fusing of sleeve oil impregnate, fuse, explosion, generation electric arc pollution transformer wet goods accident usually, influences product and normally uses, causes product to reprocess.
Oil immersion gamut plug-in fuse technological deficiency is summed up as follows:
1. insulation property aspect
Oil immersed type gamut plug-in fuse being done insulation test processing; The 1min industrial frequency withstand voltage over the ground with the alternate 95kV that reaches, fracture can reach 110kV, the lightning impulse withstand voltage peak value over the ground with alternate be 190kV; Fracture is 220kV; All comply with the national standard requirements, but fuse is done the insulation test after being installed in interior the going up of American case change casing, does not often reach the national standard requirement.The insulation property aspect also needs to improve.
2. sealing property aspect
Oil immersed type gamut plug-in fuse exterior insulation sleeve is that the metallic conduction ring is sealed in the epoxy resin; Fuse contacts through the conducting ring that is bumped in conductive pressure spring and the glass fiber epoxy tube; And be electrically connected through conducting ring and outside; Fuse can take out from the glass fiber epoxy tube through dedicated handle, at the glass fiber epoxy mouth of pipe dustproof, fool proof seal cover has been installed.When in American case change casing, moving, in the transformer oil that the insulating sleeve long period of soaking is more than 90 degree centigrade,, cause the seepage between the two easily because the coefficient of expansion of metal and epoxy resin is different.Moreover the natural conditions of wind-powered electricity generation factory are more abominable, and the some places outdoor temperature is minimum to reach subzero more than four or five ten degree.When American case change did not move, under the cryogenic conditions of subzero tens degree, the sealing ring of sleeve inner was prone to shrink insulating sleeve, also causes the seepage of sleeve easily again.In case the seepage of causing safeguards that not only cost is higher, and very inconvenience.Though fuse producer is also in continuous improvement, the sealing property of product also has increased significantly, but does not thoroughly eradicate.
3. conduction contact aspect
Domestic this product major part all is that becket and outside are electrically connected at present; Do not consider the contact area of product during many manufacturing enterprise design; The point contacting structure is more; Cause the contact point heating too high easily through electric current for a long time, can cause the electrodeposited coating carbonization of spring and becket, thereby cause the fuse contact partly to burn.Fuse member is burnt out in insulating sleeve the inside can't be taken out, and can only emit transformer oil earlier, changes the fuse insulating sleeve, safeguards also very not aspect, and cost is also high.
4. temperature rise aspect
In the insulating sleeve that fuse member is sealing when work always, the very little and sealing in sleeve inner space, fuse member is a heater element, and the heat that is produced can't discharge, and the temperature rise of product is too high, and long-play safety of products performance is had a greatly reduced quality.
Summary of the invention
The purpose of the utility model provides a kind of can raising the efficiency and effective anti-error panel operation mechanism.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of American case power transformation gas shiled equipment that adopts air insulation gamut protection fuse; Comprise that U.S.A uprises the pressure side panel; Uprise to press on the side panel in U.S.A and be provided with the fuse base plate; It is characterized in that: an end of ceramic insulator is fixed on the fuse base plate, on the other end of ceramic insulator, is provided with fuse dop and fuse clips, and air insulation gamut protection fuse is fixed on the fuse clips also locked through the fuse dop.
The utility model mainly contains following advantage:
1, temperature rise aspect: fuse is installed in and adopts the air dielectric conversion heat in the high pressure cabinet, can in time get rid of heat, the raising that has greatly improved of temperature rise aspect.
2, insulation aspect: gamut protection fuse utilizes the long ceramic-type insulator of 320mm-445mm to support and is installed in the high pressure cabinet, and enough spaces are arranged, and satisfies air insulation electrical safety distance, and insulation property can guarantee fully.
3, pollution, seal aspect: air insulation gamut protection fuse avoids oil immersed type gamut protection fuse to cause the pollution of transformer oil, the problem aspect the sealing at sleeve oil impregnate or fusing explosion fully.
4, conduction contact aspect: air insulation gamut protection fuse is electrically connected and adopts fuse clips to connect; Increase contact-making surface greatly; Solve the oil immersed type gamut and inserted the contact of fuse point, the problem that causes the long-play heating of contact to cause the fuse contact partly to burn.
