Description
Technical field
This utility model relates to a kind of capacitor, particularly relates to a kind of self-recovery low-voltage parallel capacitor.
Background technology
Power capacitor application in power system, the equipment of industrial product, high-potting and modern science and technology is quite varied.According to different use requirements, develop and defined many types and kind.Power capacitor can be divided into nine big classes, the most not quite clear theory by purposes difference.But the widest with regard to shnt capacitor purposes at nine big apoplexy due to endogenous wind, have the call.1000V hereinafter referred to as low voltage parallel capacitor in shnt capacitor, 1000V is referred above to high-voltage capacitor.But in the whole nation, demand mesolow shnt capacitor accounts for 70%, and high-voltage parallel capacitor accounts for 30%.Because its demand die is from during the Seventh Five-Year Plan period, China's power capacitor industry is introduced and is developed self-recovery low-voltage parallel capacitor.But some interruption of services that self healing capacitor occurs under different occasions in actual popularization and application mainly show as capacitor and are in operation heating, case swells, capacitance decline, only a few product generation blast etc..
Summary of the invention
In order to solve the problems referred to above, this utility model provides the self-recovery low-voltage parallel capacitor that a kind of volume is less, safer.
Technical solutions of the utility model are: a kind of self-recovery low-voltage parallel capacitor, including housing, the capacitor being arranged in housing, it is arranged on three binding posts of case top, it is arranged on case top for protecting the lid of binding post, described capacitor has three, three capacitor arrangements triangular in shape, and three capacitors and three binding posts are Y-connection or triangle connection, current-limiting reactor is concatenated respectively in capacitor one end, upper and lower side at capacitor is provided with the first insulating radiation layer and the second insulating radiation layer, a discharge resistance it is connected between two binding posts.
Further, form air vent between described three capacitors, described first insulating radiation layer, the second insulating radiation layer and housing are equipped with the through hole corresponding with air vent.
Further, described three binding post arrangements triangular in shape.
Further, described current-limiting reactor is high-gradient magnetism current-limiting reactor.
Further, described housing is externally provided with insulating protective layer.
Further, described housing is column type.
The beneficial effects of the utility model are: 1. arrange high-gradient magnetism current-limiting reactor in housing, absorb the high-frequency harmonic injected in electrical network, and limit inrush phenomenon, and arrange discharge resistance, prevent the earlier period damage of capacitor, increase the service life, use safer；Lower end is respectively provided with the first insulating radiation layer and the second insulating radiation layer the most on the capacitor, and insulating radiation effect is more preferable；3. the air vent formed between three capacitors, can preferably dispel the heat；4. overall structure is column type, and volume is less.

In conjunction with accompanying drawing 1, 2, a kind of self-recovery low-voltage parallel capacitor, including housing 1, the capacitor 2 being arranged in housing 1, it is arranged on three binding posts 3 at housing 1 top, it is arranged on housing 1 top for protecting the lid 4 of binding post 3, described capacitor 2 has three, three capacitor 2 arrangements triangular in shape, and three capacitors 2 and three binding posts 3 are Y-connection, high-gradient magnetism current-limiting reactor 5 is concatenated respectively in capacitor 2 one end, upper and lower side at capacitor 2 is provided with the first insulating radiation layer 6 and the second insulating radiation layer 7, a discharge resistance 8 it is connected between two binding posts 3.High-gradient magnetism current-limiting reactor 5 is set in housing, absorb the high-frequency harmonic injected in electrical network, and limit inrush phenomenon, and discharge resistance 8 is set, prevent the earlier period damage of capacitor 2, increase the service life, be respectively provided with the first insulating radiation layer 6 and the second insulating radiation layer 7 at capacitor 2 upper and lower side, insulating radiation effect is more preferable, uses safer.
As it is shown on figure 3, can also be triangle connected mode between 2, three binding posts 3 of three capacitors and three high-gradient magnetism current-limiting reactors 5.
Further, form air vent between described three capacitors 2, described first insulating radiation layer the 6, second insulating radiation layer 7 and housing 1 are equipped with the through hole corresponding with air vent.The air vent formed between three capacitors 2, can preferably dispel the heat.
Further, described three binding post 3 arrangements triangular in shape.
Further, described housing 1 is externally provided with insulating protective layer 9.
Further, described housing 1 is column type.Overall structure is column type, and volume is less.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or use similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
