Abstract
The utility model provides an on-load tap-changer separation type oil chamber which comprises an oil chamber; a change-over switch and a tap switch are arranged in the oil chamber; at least one insulated isolation layer is arranged on a rotating shaft of the tap switch; the edge of the insulated isolation layer is matched with the oil chamber in an air-tight manner; and an hydraulic fluid port is arranged on the insulated isolation layer. According to the utility model, the oil chamber is divided into a plurality of chambers, so that the diffusion efficiency of filtered oil is reduced greatly, and the degree of mixing unfiltered oil and filtered oil is reduced; and more unfiltered oil is sucked by an on-load tap changer oil filter machine, so that the efficiency of the oil filter machine is improved.
Description
Technical field
The utility model relates to the potential device field, especially, is a kind of on load tap changer cellular-type grease chamber.
Background technology
The on load tap changer oil filter 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., causes the insulating oil puncture 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 under 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 the dielectric strength and the performance of shunting switch oil, improve fail safe, the reliability of on load tap changer operation; Significantly reduce the transformer frequency of power cut, improve power supply reliability.
The on load tap changer oil filter is positioned at the fuel sucking pipe oily sucking-off that loaded tap switch oil is indoor of bottom, loaded tap switch oil chamber through a mouth of pipe; Oil after filtering is flowed back to from the top again; Such design makes oil remove partial impurities, but effect is unsatisfactory, because the oil that refluxes diffuses to each place, grease chamber rapidly through the impulse force of remnants on the one hand; The heat that produces during on the other hand owing on load tap changer work makes fry dried food ingredients give birth to thermal convection; Under the effect of two aspects, the oil that the oil that has filtered is good with not having filtration merges rapidly, has influenced the effect of oil strain greatly.
Summary of the invention
In order to address the above problem, the purpose of the utility model is to provide a kind of on load tap changer cellular-type grease chamber, and this grease chamber can strengthen the filter efficiency of on load tap changer oil filter.
The utility model solves the technical scheme that its technical problem adopted:
This on load tap changer cellular-type grease chamber comprises the grease chamber; Be provided with diverter switch and shunting switch in the said grease chamber; The rotating shaft of said shunting switch is provided with one deck dielectric isolation layer at least, the edge of said dielectric isolation layer and grease chamber's air-tight fit, and said dielectric isolation layer is provided with hydraulic fluid port.
As preferably, said dielectric isolation layer is obliquely installed, and said hydraulic fluid port is arranged on dielectric isolation layer least significant end.
As preferably, said hydraulic fluid port is provided with the filter chamber, and said filter chamber top and hydraulic fluid port join, and bottom notch also is provided with permanent magnet, and wall is provided with filter screen.
As preferably, said dielectric isolation layer has two-layer when above, and the hydraulic fluid port of said adjacent dielectric isolation layer is with relative maximum distance setting.
The advantage of the utility model is:
The grease chamber is isolated into a plurality of parts effectively reduces filter oil and the not degree of mixing of filter oil, effectively improved oil strain efficient.
Description of drawings
Fig. 1 is the structural representation of a kind of on load tap changer cellular-type of the utility model embodiment in grease chamber;
Fig. 2 is the structural representation of Fig. 1 embodiment filter chamber.
Among the figure: 1, grease chamber; 2, dielectric isolation layer; 21, hydraulic fluid port; 22, filter chamber; 23, permanent magnet; 24, filter screen; 3, rotating shaft.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Shown in Figure 1 is the planform sketch map of the embodiment in this on load tap changer cellular-type grease chamber; Fig. 2 is the structural representation of Fig. 1 embodiment filter chamber; For the ease of saying something, Fig. 1, Fig. 2 are set forth the utility model as same embodiment at present.
In the present embodiment; This on load tap changer cellular-type grease chamber comprises grease chamber 1; Be provided with diverter switch and shunting switch in the said grease chamber 1; The rotating shaft 3 of said shunting switch is provided with three-layer insulated separator 2, the edge of said dielectric isolation layer 2 and grease chamber's 1 air-tight fit, and said dielectric isolation layer 2 is provided with hydraulic fluid port 21.
Above-mentioned on load tap changer cellular-type grease chamber, said dielectric isolation layer 2 is obliquely installed, and said hydraulic fluid port 21 is arranged on dielectric isolation layer least significant end, makes impurity under the effect of gravity, be not easy to produce deposition.
Above-mentioned on load tap changer cellular-type grease chamber, said hydraulic fluid port 21 is provided with filter chamber 22, and 22 tops, said filter chamber and hydraulic fluid port 21 join; Bottom notch also is provided with permanent magnet 23, and wall is provided with filter screen 24, strengthens filter effect; Conductive impurity is in time removed, prevented fault.
Above-mentioned on load tap changer cellular-type grease chamber, the hydraulic fluid port 21 of said adjacent dielectric isolation layer 2 is with relative maximum distance setting, prolongs oil course grease chamber 1 in, reduces the filter oil and the degree of mixing of filter oil not, the enhancing grease chamber efficient of changing oil.
Above-mentioned on load tap changer cellular-type grease chamber operation principle:
Utilization is divided into a plurality of chambers with the grease chamber, greatly reduces filter oil diffuser efficiency, has reduced not filter oil and the mixability of filter oil, makes the on load tap changer oil filter suck the efficient that more not filter oil improves oil filter.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the utility model.
