Abstract

A gas insulation integrated power capacitor comprises a casing 1 provided with a capacitor unit 2, gas filled in the sealed casing 1, a radiator 3 arranged between and closely connected with the casing 1 and the capacitor unit 2. The utility model allows the heat generated from running of the capacitor unit in the integrated power capacitor to be dissipated in time, and prevents performance deterioration of the power capacitor due to bad heat dissipation; therefore realizing integrated capacitor with various capacitances formed by various medium type capacitor units, and effectively ensuring safe operation of the integrated capacitor.

Description

Gas-insulated aggregation type power capacitor

The utility model relates to a kind of high-voltage power capacitor, relates in particular to a kind of gas-insulated aggregation type power capacitor that is used for high-voltage system.

In the prior art, the gas-insulated integrated capacitor is not all considered the heat dissipation problem of capacitor, for example Chinese patent application number is a kind of gas-insulated integrated capacitor of 99234596 patent disclosure, it can burn-proof and explosion prevention, also solved simultaneously the electric insulation strength problem, but owing to do not consider that the heating of capacitor and gas are the non-conductor two big factors of heat, in actual use, because of poor heat radiation makes the capacitor performance deterioration, therefore, the capacitor type and the capacity of the high-pressure system that is applicable to all are restricted, when selected capacitor type improper: as use the film paper capacitor, or actual capacity all can dispel the heat when excessive because of insulating gas bad, and make the capacitor temperature rise too high, heat finally takes place collapse the Collapse damage.

The purpose of this utility model provides a kind of novel gas-insulated aggregation type power capacitor, when making capacitor reach fire-proof and explosion-proof, can guarantee that again it is the influence of this unfavorable factor of non-conductor of heat that capacitor is not subjected to gas, guarantee not deterioration of power capacitor runnability, the power capacitor reliability is improved.

The utility model is a kind of gas-insulated aggregation type power capacitor with heat abstractor, comprise wiring capacitance device unit 2 in the casing 1, gassy in the casing 1 of sealing, it is characterized in that between casing 1 and the capacitor unit 2 radiator 3 being arranged, radiator 3 closely links to each other with casing 1 and capacitor unit 2.

Adopt the utility model, can make that the operating heat of capacitor unit in time sheds in the aggregation type power capacitor, guarantee that the power capacitor performance can be because of the poor heat radiation deterioration, this gas-insulated aggregation type power capacitor not only can use the all-film power capacitor unit, also can use film paper composite dielectric capacitor unit, its amount of capacity no matter, but all stable performance ground operations, and there is not the sorrow that heat collapses Collapse, the integrated capacitor that makes the capacitor unit of various media types form various capacity is achieved, and has guaranteed the safe operation of integrated capacitor effectively.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is that the utility model is faced structural representation.

Fig. 2 is the utility model side-looking structural representation.

In Fig. 1, radiator 3 is heat-pipe type radiators, wiring capacitance device unit 2 in the casing 1, gassy in the casing 1 of sealing, comprise air, nitrogen, sulphur hexafluoride or their mixture, between casing 1 and the capacitor unit 2 radiator 3 is arranged, radiator 3 tilts to place, the heat absorbing end of radiator 3 down, the radiating end of radiator 3 up, the heat absorbing end of radiator 3 closely links to each other with capacitor unit 2, the radiating end of radiator 3 closely links to each other with casing 1, realizes capacitor unit 2 heat transferred that produce in service are shed to integrated capacitor casing 1.Radiator 3 can also be that other is used for conducting heat, radiating element, and the position not necessarily tilts to place and can stretch out outside the casing.

Claims

1, a kind of gas-insulated aggregation type power capacitor, comprise casing (1) interior wiring capacitance device unit (2), the interior gassy of casing (1) of sealing, it is characterized in that between casing (1) and the capacitor unit (2) radiator (3) being arranged, radiator (3) closely links to each other with casing (1) and capacitor unit (2).
