Abstract
The utility model relates to a discharge coil specially used for a shunt capacitor set, comprising an oil tank body, a winding, a high-voltage ceramic sleeve, a low-voltage ceramic sleeve, insulating oil, and a base. The oil tank body which is in a fully sealed structure is fixedly connected to the base. The oil tank body is filled with the insulating oil, and the winding is fixed on the oil tank body. The high-voltage ceramic sleeve and the low-voltage ceramic sleeve are respectively arranged on the oil tank body. Two side walls of the oil tank body are designed in an expanding corrugation shape. The utility model overcomes the defects that the mechanical telescopic performance of the old discharge coil specially used for a shunt capacitor set is not good and the sealing performance is not strong. The utility model has the advantages of simple structure, high insulation level, and strong elasticity.
Description
The utility model relates to the special-purpose discharge coil of a kind of Shunt Capacitor Unit.
The matching used Shunt Capacitor Unit special use of present and electrical network capacitor group discharge coil, its sealing property is not good enough, under summer in winter natural temperature differential condition, move, easy seepage, the severe contamination site environment, owing to also need the breakdown oil filler point to breathe during operation, reduce insulation level so moisture and dust are entered.For solving sealing problem, 96208845.5 number patent disclosure a kind of special-purpose discharge coil of Shunt Capacitor Unit of all-sealed structure, mechanical-stretching problem when solving inner heat expansion over pressure, above-mentioned patented technology is solved by at the oil box inner bottom part metal compensator being set, facts have proved yet use, this kind structure can not effectively solve the mechanical-stretching problem, thereby makes the sealing property of the special-purpose discharge coil of Shunt Capacitor Unit also be subjected to certain restriction, even influences safe in utilization.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby provides a kind of mechanical-stretching stronger, and effectively improves the special-purpose discharge coil of Shunt Capacitor Unit of sealing property.
The utility model comprises that oil box, line group, high voltage porcelain bushing, low pressure insulator, insulating oil and base, oil box are all-sealed structure, and be fixed on the base, fill insulating oil and fixing winding in it, high voltage porcelain bushing and low pressure insulator are set respectively on the oil box, and the two side of oil box is designed to the corrugated that expands.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises that oil box 1, winding 2, high voltage porcelain bushing 3, low pressure insulator 4, insulating oil 5 and base 6, high voltage porcelain bushing 3 and low pressure insulator 4 are arranged on outside the oil box 1, and with being welded into all-sealed structure with oil box 1 after winding 2 connections, oil box 1 is fixed on the base 6 simultaneously.Oil box 1 inner chamber fills insulating oil 5 under the constant temperature vacuum condition; winding is fixed in the oil box 1; the two side 7 of oil box 1 is designed to the corrugated that expands; to satisfy the needs of mechanical-stretching under different temperature difference conditions; the two side 7 outer upper shield protective covers 8 of oil box 1 play the purpose that protection expansion corrugated sidewall 7 is not subjected to external impacts.In use, with high voltage porcelain bushing 3 Shunt Capacitor Unit, to make the usefulness of discharge, after low pressure insulator 4 adopted the delta connection serial connection, the one head was taken over the electric protection part.
Adopt the special-purpose discharge coil of Shunt Capacitor Unit of said structure the insulating oil leakage problem can not take place in use, reduced environmental pollution, also improved simultaneously insulation level, because the compensating action of expansion corrugated sidewall, its mechanical-stretching performance also can meet the demands, the special-purpose discharge coil of a kind of desirable Shunt Capacitor Unit of therefore can yet be regarded as.
Claims (2)
