Description
The utility model relates to the high voltage shunt capacitor, and is especially relevant with no oily self-healing high voltage shunt capacitor.
Traditional high voltage shunt capacitor all be with capacitor package in the iron-clad of a sealing and fill with oil, because oil is flammable and incompressible, therefore break down as capacitor inside, then oil pressure increases, shell can explode, oil can burn, this will cause very big harm, so the class capacitor can not use in the high occasion of fire protection requirement, just forbid this type of capacitor as bustling urban district, in addition, this class capacitor is because by integral body of shell Bao Lvcheng, so it is once making, its voltage and capacitance can not change, the needs that the user can't change according to oneself change, and this type of capacitor has been broken also inconvenience at some parts and changed and maintenance simultaneously.
The purpose of this utility model is that a kind of high voltage shunt capacitor will be provided, and it need not oil-filled, uses danger greatly to reduce; In addition, its capacitor cell can be done various cordwood system type combinations, thereby series and parallel becomes the high voltage shunt capacitor of different voltages, different capabilities, and owing to there is not metal shell, can carry out repair and replacement easily when the respective capacitances unit damages.
The utility model is made up of capacitor cell, gusset piece, lead-out wire and post insulator.Its capacitor cell has an insulation crust, in this shell, is fixing upper and lower two metal splints by the insulated support of both sides, is processed with screw on the metal splint and is furnished with bolt.In parallel several metallization film capacitor element and discharge resistors between two metal splints through the resin embeddings, the lower end of each capacity cell all is equipped with one and is prevented that the sealing resin insulation that leaks outside of being heated from trapping, when element segmentation coiling, be with a shading ring in the metallization film capacitor element outside, more than shading ring wide, distance between the following metal splint is determined, for the current potential that makes shading ring suitable with the current potential in the capacitor element, adopted following method: the discharge resistor between two metal splints is formed by connecting by the series connection of the resistance more than two groups, its resistor two ends connect respectively, following metal splint, the series connection point in the resistor connects shading ring; Being connected by the screw on the clamping plate between unit and the unit realized that by gusset piece gusset piece is the rectangle metal batten, and the connection screw is arranged on the plate; Post insulator is common high voltage post insulator; Lead-out wire can be metallic bus bar row, also can be high-tension cable.During assembling the utility model, a plurality of capacitor cells both can make up by horizontal or vertical unidirectional building blocks, but the also comprehensive building blocks combination of vertical and horizontal direction, and post insulator is fixed in the middle of the bottom or cordwood system type assembly of building block assembly.
The utility model is compared with traditional high voltage shunt capacitor has following advantage: 1. do not have oil, avoided oil-filled burning that may cause of traditional capacitor and blast; 2. cordwood system type, but the voltage of root a tree name customer requirements and capacity carry out arbitrary combination, and, have bigger radiating surface because the unit fully is exposed in the air, so good heat dissipation; 3. production installation, transportation and easy to maintenance.
