Abstract
The utility model provides a load tap changer oil conservator. The load tap changer oil conservator comprises a load tap changer oil chamber and an oil conservator, wherein the oil conservator is positioned on the top of the load tap changer oil chamber, the oil conservator and the load tap changer oil chamber are communicated through a flexible pipeline, the top of the oil conservator is provided with a breather pipe, the breather pipe is provided with an air pump, a flexible thin film divides air and electric insulating oil inside the oil conservator, the air and the electric insulating oil are placed inside the oil conservator, and the air pump is a constant pressure air pump. The load tap changer oil conservator can enable possible gas inside the load tap changer oil chamber to enter the inside the of the oil conservator timely, so that safe operation of a load tap changer is guaranteed.
Description
Technical field
The utility model includes the on-load shunting switch apparatus field, especially, is a kind of conservator on load tap changer.
Background technology
On load tap changer is a kind of switching device that constant voltage is provided when the load variations for transformer.Its basic principle is exactly to guarantee in the situation of interrupt load electric current not, realizes the switching between the tap in the Transformer Winding, thereby changes the number of turn of winding, i.e. the voltage ratio of transformer finally realizes the purpose of pressure regulation.On-load tap changers of transformers online oil filtration machine is to switch in the grease chamber in order to solve on-load voltage regulating switch, because arcing, insulating oil very easily decomposes, wears out and produces a large amount of free carbons and metal fragment etc., cause insulating oil breakdown voltage to reduce, the product of dielectric property variation the problems referred to above research and development.It is mainly used in the filtration of transformer on-load tap changer insulating oil.Equipment can be in the situation of the normal operation of transformer, switch instances automatic on-line oil strain according to tap changer, effectively remove free carbon, moisture, cracking impurity and acid in the oil, recover dielectric strength and the performance of tap switch oil, improve on load tap changer Operation safety, reliability, greatly reduce the transformer frequency of power cut, improve power supply reliability.
The on load tap changer top generally all is equipped with conservator, the effect of conservator is in order to make on load tap changer inside immerse reliably in the insulating oil, the air that may enter in the timely emptying load tap changer oil chamber, guaranteed safe operation, but gas its volume under the effect of atmospheric pressure and insulating oil self gravitation that in fact produces in the grease chamber is mostly minimum, is unfavorable for that the gas rising enters conservator.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of loaded tap switch oil pillow, and the gas that this conservator can make load tap changer oil chamber inside exist in time enters in the conservator.
The technical scheme that its technical problem that solves the utility model adopts is:
This loaded tap switch oil pillow comprises load tap changer oil chamber and conservator, described conservator is arranged on described load tap changer oil chamber top, both are communicated with by a flexible duct, described conservator top is provided with breather pipe, be provided with air pump on the described breather pipe, air and the insulating oil of conservator inside separated in described conservator inside by a fexible film.
As preferably, described air pump is pressure constant air pump, and namely pressure raises or reduces, the atmospheric pressure value that described air pump can automatic stabilisation be set.
As preferably, described atmospheric pressure value is lower than 1/2nd atmospheric pressure.
The utility model has the advantage of: with fexible film in the conservator every air side carry out step-down, can effectively reduce the pressure in the on load tap changer, make the easier rising of micro-bubble, guaranteed the safe operation of on load tap changer.
Description of drawings
Fig. 1 is the structural representation of an embodiment of this loaded tap switch oil pillow.
Among the figure: 100, load tap changer oil chamber; 200, conservator; 210, breather pipe; 211, air pump; 220, fexible film; 230, flexible duct.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Figure 1 shows that the planform schematic diagram of an embodiment of this loaded tap switch oil pillow.
In the present embodiment, this loaded tap switch oil pillow comprises load tap changer oil chamber 100 and conservator 200, described conservator 200 is arranged on described load tap changer oil chamber 100 tops, both are communicated with by a flexible duct 230, described conservator 200 tops are provided with breather pipe 210, be provided with air pump 211 on the described breather pipe 210, air and the insulating oil of conservator inside are separated by a fexible film 220 in described conservator 200 inside.
Above-mentioned loaded tap switch oil pillow, described air pump 211 is pressure constant air pump, namely pressure raises or reduces, the atmospheric pressure value that described air pump 211 meeting automatic stabilisations are set.
Above-mentioned loaded tap switch oil pillow, described atmospheric pressure value is 1/4th atmospheric pressure, lower atmospheric pressure value is beneficial to the pressure that reduces in the load tap changer oil chamber, the too low easy generation gas leakage situation of atmospheric pressure value.
The principle of above-mentioned loaded tap switch oil pillow:
Described air pump is reduced to 1/4th atmospheric pressure with the air pressure of conservator 200 Air sides, the insulating oil side of described conservator 200 is depressed owing to still being in normal atmosphere, therefore described insulating oil 200 sides are subjected to the attraction of air side, since the counteract gravity forces of insulating oil air side air pressure attraction and form a balance, this moment, insulating oil side and load tap changer oil chamber 100 interior pressure were reduced, therefore micro-bubble can be expanded fast rise, has guaranteed the safe operation of on load tap changer.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
