Description
Technical field
The utility model relates to the filtering oil for transformer apparatus field, especially, is a kind of online oil filtration device on load tap changer.
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, methane gas and metal particle etc., cause insulating oil breakdown voltage to reduce, dielectric property variation the problems referred to above and the product researched and developed.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.
Existing oil filter can be removed free carbon, the metal particle in the oil cabinet of tap switches and the content that reduces minor amount of water, but the methane gas that can not filtering produces because of electric arc, although the recharging oil device of shunting switch can be got rid of a part of gas in the grease chamber, but still have structure complicated in microbubble and grease chamber and the oil filter to still have space and the dead angle of depositing gas in the circuit-breaker oil, if these residual gases of depositing in headroom and the dead angle reenter untimely filtering in the circuit-breaker oil, for shunting switch, be harmful to.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of shunting switch online oil filtration device, and the gas oil separation structure in this oil filter can effectively be removed the methane gas in the circuit-breaker oil.
The technical scheme that its technical problem that solves the utility model adopts is:
This shunting switch online oil filtration device comprises cabinet and is arranged at the contaminant filter that is linked in sequence by pipeline in the cabinet, except water filter and oil pump, described oil filter also comprises a gas oil separation structure, described gas oil separation structure horizontal vertical is arranged in the cabinet, described gas oil separation structure comprises the tank body of a top band end cap, be provided with at least one oil outlet around the described tank base, described tank base center is provided with fuel feed hole, the axle center of described tank body arranges a rotating shaft, described rotating shaft is passed described end cap and is connected a motor in the tank body outside, be evenly equipped with at least two isolation blades around the described rotating shaft, described end cap top is provided with the gas storage storehouse, and top, described gas storage storehouse is provided with air extraction hood.
As preferably, high in the middle of described end cap is around low shape.
As preferably, described isolation blade has four.
As preferably, described oil outlet has four, and is distributed in tank base.
The utility model has the advantage of:
After on load tap changer carried out oil strain, the device in Gas physical efficiency in the circuit-breaker oil was effectively removed, thereby had strengthened stability and the durability of on load tap changer.

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 tap switch online oil filtration device, Fig. 2 is the structural representation of Fig. 1 embodiment gas oil separation structure, Fig. 3 is that the axle of isolation blade in Fig. 2 embodiment gas oil separation structure is surveyed schematic diagram, problem is now set forth as same embodiment Fig. 1, Fig. 2 and Fig. 3 to the utility model for convenience of explanation.
In the present embodiment, this shunting switch online oil filtration device comprises cabinet 10 and is arranged at the contaminant filter 100 that is linked in sequence by pipeline in the cabinet 10, except water filter 101 and oil pump 103, described oil filter also comprises a gas oil separation structure 102, described gas oil separation structure 102 horizontal vertical are arranged in the cabinet 10, described gas oil separation structure 102 comprises the tank body 1 of a top band end cap 2, be evenly equipped with four oil outlets 12 around described tank body 1 bottom, described tank body 1 bottom centre is provided with fuel feed hole 11, the axle center of described tank body 1 arranges a rotating shaft 3, described rotating shaft 3 is passed described end cap 2 and is connected a motor 4 in tank body 1 outside, be evenly equipped with four isolation blades 31 around the described rotating shaft 3, described end cap 2 tops are provided with gas storage storehouse 21, and 21 tops, described gas storage storehouse are provided with air extraction hood.
Low shape around high in the middle of above-mentioned shunting switch online oil filtration device, described end cap 2 are is so that the easier gas storage storehouse 21 that enters of methane gas.
Above-mentioned shunting switch online oil filtration device, described end cap 2 is made for transparent resin or glass material.
Above-mentioned shunting switch online oil filtration device operation principle and occupation mode:
The circuit-breaker oil that contains gas that the loaded tap-off grease chamber produces flows into gas oil separation structure 102, because the methane gas that produces is present in the circuit-breaker oil with minimum volume, traditional leaving standstill makes the mode of bubble rising invalid or too slow, critically in time gas is separated from circuit-breaker oil, adopt centrifugal mode, because under the promotion of isolation blade 31, the motion of circuit-breaker oil high speed centrifugation, the G value that circuit-breaker oil bears under the effect of centrifugal force increases greatly, although and methane gas also strengthens, but be far smaller than the added value of circuit-breaker oil, this moment, methane gas was drawn close to tank body 1 center and top rapidly under the effect of the extruding of circuit-breaker oil and buoyancy, methane gas is gathered in tank body 1 middle and upper part and the final gas storage storehouse 21 that flows into thus, and the circuit-breaker oil by gas-removing flows back to load tap changer oil chamber around from tank body 1 bottom.Along with methane gas is more and more at end cap 2 tops, the operation of bleeding of the air extraction hood that need to open gas storage storehouse 21.
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.
