Abstract

The utility model provides a transformer oil tank. The transformer oil tank comprises a tank body, wherein at least one separating plate is arranged in the tank body, the internal space of the tank body is divided by the separating plate into two oil chambers which are separated from each other, one oil chamber serves as a transformer oil chamber, the other oil chamber serves as a switch oil chamber, a wall bushing is installed on the separating plate, the wall bushing and the separating plate are sealed, and an oil filling opening and an oil discharge outlet are formed in the switch oil chamber. According to the transformer oil tank, the independent switch oil chamber is arranged, a high-voltage load switch and a high-voltage fuse are installed in the switch oil chamber, the switch oil chamber and the transformer oil chamber are independent from each other, free carbon, acetylene and other impurities generated in the process of switching of the high-voltage load switch or movement of the high-voltage fuse cannot have an influence on transformer oil, and therefore operation safety and operation reliability of a transformer are improved; in addition, when a user removes the impurities, only oil in the switch oil chamber needs to be filtered, and therefore the workload of maintenance of a box transformer substation is reduced.

Description

Oil tank of transformer

Technical field

The utility model relates to transformer technology, relates in particular to a kind of oil tank of transformer.

Background technology

American transformer is a kind of Combined type power equipment of having integrated high voltage switchgear, distribution transformer, low-voltage distribution equipment, and using transformer oil as high voltage load switch and the insulation of high-tension fuse and arc-extinguishing medium.Use at present comparatively generally, domestic American-type box accommodation is often placed in same fuel tank by high voltage load switch and high-tension fuse and transformer.Under this kind of mounting means, in the time that case becomes high voltage load switch switching or high-tension fuse action, all can produce free carbon, acetylene and other impurity; These materials all can threaten to the safety of transformer, reliability service.And case change user need to filter the oil that whole case becomes in the time removing these impurity, this has also increased case and has become the workload of safeguarding.

Utility model content

The utility model provides a kind of oil tank of transformer, be used for overcoming defect of the prior art, the free carbon, acetylene and other impurity that when high voltage load switch switches or high-tension fuse moves, produce can not exert an influence to transformer oil, greatly improve safety, the reliability of transformer operation.

The utility model provides a kind of oil tank of transformer, comprise casing, in described casing, there is at least one dividing plate described box house is divided into two grease chambeies separated from one another, one of them grease chamber is transformer grease chamber, another grease chamber is switch grease chamber, on described dividing plate, wall bushing is installed, between described wall bushing and described dividing plate, seals, described switch grease chamber is provided with pouring orifice and fuel outlet.

Wherein, on described pouring orifice and fuel outlet, be equipped with valve.

Further, described pouring orifice is located at top, described switch grease chamber, and described fuel outlet is located at bottom, described switch grease chamber.

Particularly, the size of described switch grease chamber is less than the size of described transformer grease chamber.

Further, described transformer grease chamber and described switch grease chamber are all square, and described switch grease chamber is positioned at top, described transformer grease chamber.

The oil tank of transformer that the utility model provides, independent switch grease chamber is set, it is indoor that high voltage load switch and high-tension fuse are arranged on this circuit-breaker oil, switch grease chamber and transformer grease chamber are separate, the free carbon, acetylene and other impurity that when high voltage load switch switches or high-tension fuse moves, produce can not exert an influence to transformer oil, this has improved safety, the reliability of transformer operation greatly, and, user only needs to filter the oil of switch grease chamber in the time removing these impurity, and this has also reduced case and has become the workload of safeguarding.

Accompanying drawing explanation

The structural representation of the oil tank of transformer that Fig. 1 provides for the utility model embodiment.

Embodiment

As shown in Figure 1, the utility model provides a kind of oil tank of transformer, comprise casing 1, in casing 1, there is at least one dividing plate 2 box house is divided into two grease chambeies separated from one another, one of them grease chamber is transformer grease chamber 11, and another grease chamber is switch grease chamber 12, and wall bushing 3 is installed on dividing plate 2, sealing between wall bushing 3 and dividing plate 2, switch grease chamber 12 is provided with pouring orifice 121 and fuel outlet 122.

The oil tank of transformer that the utility model provides, independent switch grease chamber 12 is set, high voltage load switch 12a and high-tension fuse 12b are arranged in this switch grease chamber 12, transformer 11a is arranged in transformer grease chamber 11, separate between switch grease chamber 12 and transformer grease chamber 11, the free carbon producing when high voltage load switch 12a switches or high-tension fuse 12b moves, acetylene and other impurity can not exert an influence to the oil in transformer grease chamber 11, this has improved the safety of transformer operation greatly, reliability, and, user only needs to filter the oil in switch grease chamber 12 by fuel outlet 122 in the time removing these impurity, after filtration, refill in switch grease chamber 12 by pouring orifice 12a, this has also reduced the workload that oil tank of transformer is safeguarded.

For handled easily, on pouring orifice 121 and fuel outlet 122, be equipped with valve 123.Controlled valve 123 while filtering oily in switch grease chamber 12.

Further, pouring orifice 121 is located at 12 tops, switch grease chamber, and fuel outlet 122 is located at 12 bottoms, switch grease chamber.Be convenient to oily injection and discharge.

Wherein, the size of switch grease chamber 12 is less than the size of transformer grease chamber 11.The volume of switch grease chamber 12 is 15% left and right of the volume of transformer grease chamber 11 under normal circumstances, and the oil mass of switch grease chamber 12 is only 15% left and right of transformer grease chamber 11 oil masses, and this will reduce the workload of oil tank of transformer maintenance greatly.

Further, transformer grease chamber 11 and switch grease chamber 12 are all square, and switch grease chamber 12 is positioned at 11 tops, transformer grease chamber.Convenient transformer 11a, high voltage load switch 12a and the high-tension fuse 12b of installing, conserve space, is easy to being connected of transformer 11a and high-tension fuse 12b.
