Abstract
The utility model provides an external inflation ware of condenser, oily formula in adopts, oiling under the vacuum to be connected the fastening with coupling nut, sealing washer, fuel outlet valve, spring etc. Become independent self sealss inflation ware, again with through the heating, take out vacuum treatment, high vacuum under the capacitor body of oiling assemble the back, the fuel outlet valve of inflation ware is opened, the oil circuit that makes inflation ware and ware body unimpededly. When the condenser when lower limit temperature moves, the oily volume contraction of insulation in the ware body is compensated by the insulating oil in the inflation ware at any time, when the condenser when upper limit high temperature moves, the oily volume expansion of insulation in the ware body, go into inflation ware with its expanded insulating oil top in to guarantee that the insulating oil of condenser in height, low temperature within range ware body effectively obtains the compensation. This inflation ware need not not be beaten surplus oil pressure, simplifying processing process for the condenser, avoid the excessive waste that causes of insulating oil, and the compensation effect is directly perceived, and convenient operation improves product quality, and economic benefits and social are higher.
Description
Technical field
The utility model relates to the power equipment used in a kind of electrical network, relates to the external-expander of a kind of coupling capacitor and capacitor voltage divider specifically.
Background technology
Coupling capacitor and capacitor voltage divider are the electric equipments for electric power system carrier wave, communication and overvoltage protection.This condenser voltage grade mostly is 35kV to 750kV high voltage product, in order to solve main insulation, its shell all adopts high voltage electric porcelain sleeve, upper and lower flange is two electrodes, capacitor body and insulating oil are equipped with in inside, because insulator cannot compensate the Swelling and contraction of insulating oil caused by variation of ambient temperature, all adopt the compensation method at the built-in conventional expanders of insulator at present, and a certain amount of superfluous oil pressure to be beaten to capacitor, to make it negative pressure can not be occurred in design temperature change inner capacitor inside, ensure its electric property.This structure has following defect: one be buy oil pressure process in have steam bubble to enter capacitor internal, affect electric property and local discharging level; Two is that when buying oil pressure, capacitor internal insulating oil is much excessive, cannot reclaim and cause waste; Three have just taken out flat in vacuumizing phase when being expander defectiveness because of leakage, do not have compensating action, affect capacitor product quality.
Summary of the invention
The oily compensating defective that the utility model exists for existing capacitor, proposing one does not need buy oil pressure, easy to operate, the simple capacitor external-expander of structure.
The concrete technical scheme solved the problem is:
A kind of capacitor external-expander, it is characterized in that: be made up of expander device body 1, attaching nut 2, fuel outlet valve 3, fuel outlet valve sealing ring 4, fuel outlet valve linking springs 5 and expander sealing ring 6, wherein, expander device body 1 is connected with attaching nut 2, expander device body 1 is provided with fuel outlet valve 3, fuel outlet valve 3 is provided with fuel outlet valve linking springs 5, is provided with fuel outlet valve sealing ring 4 between attaching nut 2 and fuel outlet valve 3, between expander device body 1 and attaching nut 2, be provided with expander sealing ring 6.
good effect of the present utility model is:(1) unique external-expander structure: the oiling all under vacuum conditions of expander and capacitor body, without the need to especially repairing, makes capacitor vacuum performance good, improve its electric property and local discharging level; (2) expander independently self sealing structure: solve the waste problem that insulating oil when assembling with capacitor body is excessive, both saved raw material, also improve the sealing property of junction; (3) cut the process procedure of a pressure of buying oil, i.e. process simplification, also reduces the labour intensity of operator; (4) when not changing insulator size, the limited utilance that improve its inner space.The utility model is easy to operate, and technical process simplifies, and economic benefits comparison is remarkable.

Embodiment
A kind of capacitor external-expander, as shown in Figure 1, Figure 2 and Figure 3, be made up of expander device body 1, attaching nut 2, fuel outlet valve 3, fuel outlet valve sealing ring 4, fuel outlet valve linking springs 5 and expander sealing ring 6, wherein, expander device body 1 is connected with attaching nut 2, expander device body 1 is provided with fuel outlet valve 3, fuel outlet valve 3 is provided with fuel outlet valve linking springs 5, between attaching nut 2 and fuel outlet valve 3, be provided with fuel outlet valve sealing ring 4, between expander device body 1 and attaching nut 2, be provided with expander sealing ring 6.The compensation way of this external-expander, structure and conventional expanders have relatively big difference, external-expander adopts filled with oil formula, expander device body completes oiling under vacuum conditions, after being fastened and connected with each assemblies such as attaching nuts, become independently self-sealing expansion device, process again with through heating, vacuumizing, after the capacitor body of oiling assembles under high vacuum, the fuel outlet valve of expander is opened, and makes the oil circuit of expander and device body unimpeded.When capacitor runs at lower limit temperature, the insulating oil volume contraction in device body, is compensated at any time by the insulating oil in expander; When capacitor runs at upper limit high-temperature, the insulating oil volumetric expansion in device body, the insulating oil expanded heads in expander.This is self sealss external-expander collocation structure independently, superfluous oil pressure, process simplification need not be beaten to capacitor, avoid excessive the caused waste of insulating oil, compensation effect is directly perceived, improve the quality of products, ensure that capacitor runs under high and low temperature environment, the insulating oil of its device body inside is all effectively compensated.
The contour structures of conventional expanders as shown in Figure 4, it is the expander that a kind of longitudinal direction has ripple, both ends of the surface seal welding, be built in capacitor body inside, after capacitor general assembly, need to beat a certain amount of superfluous oil pressure to capacitor, to ensure can not occur negative pressure in design temperature change inner capacitor inside.When capacitor runs at lower limit temperature, because there is superfluous oil pressure capacitor inside before dispatching from the factory, expander is compressed, so time expander can start resilience gradually, with insulating oil volume contraction in compensator body; When capacitor runs at ceiling temperature, along with the insulating oil volumetric expansion in device body, and compression-expansion device, and the overpressure of capacitor internal is no more than certain value (preventing insulator from expanding broken), thus ensure that the insulating oil of capacitor within the scope of high and low temperature in performer body all can be compensated.But capacitor-embedded expander has following defect: one be buy oil pressure process in have steam bubble to enter capacitor internal, affect electric property and local discharging level; Two is that when buying oil pressure, capacitor internal insulating oil is much excessive, cannot reclaim and cause waste; Three have just taken out flat in vacuumizing phase when being expander defectiveness because of leakage, do not have compensating action, affect product quality.
