Abstract
The utility model discloses a capacitor, which comprises an oil tank, a capacitor shell arranged on the upper part of the oil tank and wiring terminals fixed on the capacitor shell. Each wiring terminal comprises an insulator body, a metal wiring bolt arranged on the top of the insulator body and a metal mounting seat arranged on the lower part of the insulator body. A plastic package sleeve fixedly connected with an insulator body and a mounting sleeve connected with the capacitor shell are arranged on each metal mounting seat. The plastic package sleeve of each metal mounting seat is plastically packaged on the lower part of a corresponding insulator body in an injection molding way or a compression molding way. A bracket is arranged on the middle part of the lateral surface of the oil tank. A bearing frame for preventing a core from falling is arranged in the oil tank of the capacitor. A silicone rubber protective sleeve is arranged on the outer wall of each insulator body. Each metal mounting seat is substantially tubular. Each plastic package sleeve is positioned in a hole cavity enclosed by a corresponding mounting sleeve. The capacitor is simple in structure, safe, reliable, convenient to mount and disassemble, high in sealing performance and low in production and using cost.
Description
Technical field
The utility model relates to a kind of electric installation field, relates in particular to a kind of capacitor.
Background technology
The high-voltage capacitor that is used for electric power system and electrical equipment generally is made up of cylinder, cylindrical shell top, flat cover or hemisphere shape end socket, potted component and some annexes.The size of condenser capacitance is decided by the characteristic of dielectric between its physical dimension and two-plate.
Present power capacitor, still use the binding post of ceramic insulator as main body, main cause is that most power capacitor is for fear of the internal liquid seepage more; Need the whole comparatively strict sealing property that has; In addition, because power capacitor is compared with other High-Voltage Electrical Appliances mostly, price is comparatively cheap; In order to keep competitiveness, also have to use low-cost pottery as the binding post main body.The binding post that this pottery is processed is because parts are more, and assembling one by one, thus cause its processing technology loaded down with trivial details, and easy occurrence of waste; Pottery dodges poor-performing than great, frangible and anti-soil, so the structure of this traditional binding post is still needed improvement badly.
The support of existing capacitor all adopts right angle rack, and no bearing support in the fuel tank of capacitor, and procedure of processing is increased; Also have potential safety hazard in addition, when capacitor was blasted, fuse and oil fell down together, are easy to generate burning, breaking out of fire.
The utility model content
In view of this, the purpose of the utility model provides a kind of capacitor.
The technical scheme of the utility model realizes with following method,
A kind of capacitor; Comprise fuel tank; The capacitor casing that is arranged on fuel tank top be fixed on the binding post on the capacitor casing, binding post comprises insulator body, be arranged on the metal connection bolt on insulator body top and be arranged on the metal installation base of insulator body bottom; Metal installation base is provided with the plastic packaging cover and the installation sleeve that is used for linking to each other with capacitor casing that is used for the insulator body fixed connection; The plastic packaging of metal installation base cover in the bottom of said insulator body, is equipped with support in the middle part of the side of fuel tank through injection mo(u)lding or compression molding plastic packaging, and the bearing support that prevents that fuse from falling down is housed in the capacitor fuel tank.
The outer wall of insulator body is provided with the silicon rubber protective sleeve.
The basic configuration of metal installation base is a tubulose.
The plastic packaging cover is in the vestibule that said installation sleeve surrounds, and said installation sleeve is on the outer wall of said insulator body.
The good effect of the utility model technical scheme is:
The utility model is simple in structure, safe and reliable, easy installation and removal, and good seal performance has reduced production and use cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
