Abstract
The utility model provides a box type integrated high voltage shunt capacitor. A high voltage shunt capacitor bank is composed of a high voltage capacitor unit, a discharge coil and an arrester. A fuse wire is arranged on the high voltage capacitor unit. The utility model is characterized in that the high voltage shunt capacitor bank is directly installed in a box body whose top side is provided with an insulated connecting terminal, the surface of the box body is provided with an air-vent, and the front face of the box body is provided with a movable door. The utility model has the advantages that the natural air cooling can be implemented, and the problem of pollute environment caused by the oil and gas leakage of the original assembling capacitor is overcome; the weight is light and the cost is low; an outdoor box-type structure is adopted, and a house is not needed to be built to prevent; the installation and the repair are convenient, and the capacitor unit or other fittings can be changed at site.
Description
Technical field
The utility model relates to the box HV Capacitor with Internal shunt capacitor that uses in a kind of electric power system.
Background technology
The HV Capacitor with Internal shunt capacitor is used for connecting frequency 50HZ or the 60HZ rated voltage is higher than the above AC electric power systems of 1000V, is used to improve power factor, reduces line loss, improves the supply power voltage quality.Original HV Capacitor with Internal shunt capacitor is made up of several capacitor units and is contained in the shell of all-sealed structure, and is oil-filled or fill SF in the shell
6Gas.Not only Heavy Weight, bad, the temperature rise of heat radiation, operation are unreliable for it, and oil and gas leaks easily, cause environmental pollution; Because original HV Capacitor with Internal capacitor, can't keep in repair at the scene in case capacitor unit is out of service for for hermetically-sealed construction.Even maintenance, the time between overhauls(TBO) reaches 2～3 months, and round transport expense costliness, brings economic loss to the user.
Summary of the invention
The objective of the invention is to provide a kind of good heat dissipation, temperature rise low, in light weight, free from environmental pollution, safe and reliable to operation, the box easily HV Capacitor with Internal shunt capacitor of installation and maintenance.
The utility model is achieved in that it forms the high-voltage parallel capacitor group by high-voltage capacitor unit and discharge coil, lightning arrester, on the high-voltage capacitor unit, be provided with fuse, its special character is that said high-voltage parallel capacitor group is directly installed in the casing, be provided with the insulation joint terminal at box top, be provided with ventilation hole in tank surface, be provided with dodge gate in the casing front.
According to above-mentioned box HV Capacitor with Internal shunt capacitor, said fuse is outside the high-voltage capacitor unit and be serially connected between insulation joint terminal and the high-voltage capacitor unit connection end, to solve owing to the design error of interior fuse and the heterogeneity of manufacturing process, some cell fuse is because of overcurrent overvoltage misoperation, cause the cell capability variation or cause the group quick-fried because of many fuses fuse simultaneously, the unit is forced to problem out of service, improves job security, the reliability of whole box HV Capacitor with Internal shunt capacitor.
Box HV Capacitor with Internal shunt capacitor according to above-mentioned is provided with axial flow blower at the casing inner top, to improve result of ventilating heat dissipation.
The utility model has the advantages that and to realize natural draft cooling, overcome the oil and gas leakage of former integrated capacitor and problem of environment pollution caused; In light weight, cost is low; Adopt the outdoor box structure, the room protection need not to build a house in addition; Installation and maintenance are convenient, can change capacitor unit or other parts at the scene.
