Description
Technical field
The utility model relates to a kind of novel high-pressure power capacitor, belongs to the high-voltage power capacitor technical field of structures.
Background technology
High-voltage capacitor be a kind of mainly by pole plate and contrasted between solid dielectric thereof by the element that the form of reeling is made into, then element is combined into capacitor body by series-parallel form and is loaded in the casing, draw by capacitor casing at the two poles of the earth of capacitor body.Existing high-voltage capacitor structural design is unreasonable, mainly have following shortcoming: 1, the ceramic insulator of capacitor is with silver installation portion and ceramic body to be welded together, make it firmly to be fixed on the ceramic body, this production cost is high, long processing time and contaminated environment; 2, in HVDC (High Voltage Direct Current) transmission system, have a large amount of harmonic waves, when harmonic current flow through power capacitor, power capacitor internal electrode and insulating material were subject to the impact of the distortion electric field power that harmonic wave produces and shake, cause the also simultaneously vibration of power capacitor integral body, make a noise.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, and cost of manufacture is low, and production process is polluted little, the novel high-pressure power capacitor that noise is little during work.
The utility model is achieved through the following technical solutions:
A kind of novel high-pressure power capacitor, comprise metal cabinet and be packaged in two capacitor core bodies that have spacing in the metal cabinet, the top of metal cabinet is provided with the porcelain bushing that is connected with capacitor core body, its special character is that porcelain bushing comprises insulator body, the top of insulator body is equipped with connector assembly, the bottom outer wall of insulator body is welded with metal installation base, also is provided with sealing ring between insulator body and the metal installation base, and the top of capacitor core body is provided with noise eliminator;
Described noise eliminator comprises the support that is column type, it is 3 millimeters insulating board that the bottom of support and sidewall are coated with thickness, it is the abatvoix that 1.5 millimeters insulating board is made that the top of support is equipped with by thickness, be laid with through hole on the abatvoix, internal stent is equipped with the aluminium foil of 0.15 millimeter of layer 2-3;
The outer surface of described capacitor core body is coated with the high pressure resistant insulation layer;
The outside of the high pressure resistant insulation layer of described capacitor core body is equipped with the metallic plate that shields.
High-voltage power capacitor of the present utility model; reasonable in design; insulator body adopts welding manner to be connected with metal; therefore can significantly reduce manufacturing cost; exceptionally favourable to the environmental protection aspect, the utility model is provided with noise eliminator, the vibrations of energy establishment capacitor core body; when not affecting properties of product, realize the quiet effect of product noise reduction, the utlity model has good application prospect.
