Abstract
The utility model relates to a special discharging coil for a parallel condenser bank, which is composed of an upper cover, high and low voltage porcelain sleeves, a coil, an iron core, and insulating oil. The housing has a fully sealing structure, a corrugated expanding ring is arranged on the housing, and an air gap is arranged between the insulating oil and the upper cover to respectively satisfy the requirements for the mechanical expansion and contraction of the housing and the required space of the expansion of the insulating oil. The utility model overcomes the defect of an ordinary special discharging coil for parallel condensers of seriousleakage and has the advantages of good sealing performance, high insulation level, etc. Simultaneously, the environmental pollution is reduced, and the utility model is an ideal special discharging coil for a parallel capacitor bank.
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, because when operation needs the breakdown oil filler point to breathe, make insulation level decline so easily enter moisture and dust, make electric power netting safe running exist very important accident potential.
The purpose of this utility model provides a kind of sealing property special-purpose discharge coil of Shunt Capacitor Unit preferably.
The utility model is made of housing, loam cake, high voltage porcelain bushing, low pressure insulator, coil, iron core and insulating oil, fill insulating oil in the housing, be arranged in the housing after coil and the iron core winding, the upper end of housing is high voltage porcelain bushing and low pressure insulator, the high-low pressure insulator is connected with coil, housing is the close structure of full envelope, is provided with air gap in it, to satisfy after the temperature rise insulating oil required space of expanding.
Also be provided with ripple harmomegathus circle on the housing, the mechanical-stretching when satisfying inner heat expansion over pressure.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model is made of housing (1), loam cake (2), high voltage porcelain bushing (3), low pressure insulator (4), coil (5), iron core (6) and insulating oil (7), high-low pressure insulator (3,4) is connected the back and is welded into all-sealed structure with housing (1) with coil (5), and under the constant temperature vacuum condition, fill insulating oil (7), leave air gap (8) between insulating oil (7) and the loam cake (2), the insulating oil required space of expanding when satisfying temperature rise.The iron core (6) that is wound with coil (5) is followed closely the lower end that is fixed in housing (1) after (12) are fixed by base plate (10) and pressing plate (11) by pressing.Also be provided with ripple harmomegathus circle (9) on the housing (1), the mechanical-stretching when satisfying inner heat expansion over pressure is executed in the example in this practicality, and ripple harmomegathus circle (9) is arranged on the sidewall and the bottom of housing (1).During use, with high voltage porcelain bushing and connect electric capacity, to make the usefulness of discharge, after the low pressure insulator adopted delta connection to be connected in series, the one head was taken over the electric protection part.
The utility model makes special-purpose discharge coil the insulating oil leakage problem can not take place in use by above-mentioned concrete structure, has reduced environmental pollution, has improved insulation property, is the special-purpose discharge coil of a kind of desirable Shunt Capacitor Unit.
Claims (2)
1, the special-purpose discharge coil of a kind of Shunt Capacitor Unit, constitute by housing, loam cake, high voltage porcelain bushing, low pressure insulator, coil, iron core and insulating oil, be full of insulating oil in the housing, be arranged in the housing after coil and the iron core winding, the upper end of housing is high voltage porcelain bushing and low pressure insulator, the high and low pressure insulator is connected with coil, it is characterized in that: housing (1) is an all-sealed structure, is provided with air gap (8) in it.
