Description
Technical field
The utility model belongs to transformer technology field, relates in particular to 800kVA and above Full-sealing corrugated oil box 10kV distribution transformer.
Background technology
Above the transformer body of 800kVA and above Full-sealing corrugated oil box 10kV distribution transformer, be provided with Buchholz relay, in this Buchholz relay grease chamber, must be full of oil could normal work.In order to guarantee to be full of oil in the grease chamber of Buchholz relay, above Buchholz relay, be provided with conservator, in conservator, be provided with transformer oil.Original common transformer is provided with conservator, and at conservator is generally that transformer for said structure exists following defect: one, conservator is set above transformer, and increased production cost and maintenance cost; Its two, this transformer is become for case, box height increases by 40---50 centimetres, cause chest height to increase, chest cost increases, and transports more difficult; Its three, between transformer and low pressure, by copper bar, be connected, between copper bar and conservator, keep insulation distance, cause copper bar length to lengthen, cost increases.
Utility model content
The technical problem of solution of the present utility model is just to provide a kind of production cost and maintenance cost is low, little 800kVA and above Full-sealing corrugated oil box 10kV distribution transformer take up room.
The technical solution adopted in the utility model is: comprise transformer body, be positioned at the sealing corrugated tank of described transformer body side and be positioned at the Buchholz relay of described transformer body top, above described transformer body, be provided with oil-level gauge base, above described oil-level gauge base, be provided with oil-level gauge, between described oil-level gauge base and described oil-level gauge, be provided with tube connector, the upper end of described tube connector is higher than described Buchholz relay upper surface.
Its additional technical feature is:
Described tube connector comprises and is arranged in the upper connecting leg of upper end, the lower connecting leg that is arranged in the ball-type tripe of connecting leg below and is positioned at this ball-type tripe below and is connected with oil-level gauge base;
Described lower connecting leg is serpentine bend pipe.
800kVA provided by the utility model and above Full-sealing corrugated oil box 10kV distribution transformer are compared with prior art, have the following advantages: one, owing to comprising transformer body, be positioned at the sealing corrugated tank and the Buchholz relay that is positioned at described transformer body top of described transformer body side, above described transformer body, be provided with oil-level gauge base, above described oil-level gauge base, be provided with oil-level gauge, between described oil-level gauge base and described oil-level gauge, be provided with tube connector, the upper end of described tube connector is higher than described Buchholz relay upper surface, the transformer oil of annotating above tube connector, after filling it up with, oil-level gauge is arranged on to tube connector top, like this, can guarantee to be full of oil in the grease chamber of Buchholz relay, making case change rear box height reduces greatly, reduced casing cost, casing carrying is more convenient, for the copper bar of connection transformer and low pressure only need get around tube connector and oil-level gauge and with its maintenance insulation distance, can greatly shorten copper bar length, they are two years old, because comprising, described tube connector is arranged in the upper connecting leg of upper end, the lower connecting leg that is arranged in the ball-type tripe of upper connecting leg below and is positioned at this ball-type tripe below and is connected with oil-level gauge base, can many splendid attires transformer oil in tripe in the ball-type of tube connector, solved because expanding with heat and contract with cold or because consuming the too low problem of pasta that causes, its three, because described lower connecting leg is serpentine bend pipe, in the situation that highly not increasing, further improved oily total amount.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model 800kVA and above Full-sealing corrugated oil box 10kV distribution transformer;
Fig. 2 is the structural representation of another kind of tube connector;
Fig. 3 is the structural representation of the third tube connector.
Embodiment
Below in conjunction with accompanying drawing, structure and the use principle of the utility model 800kVA and above Full-sealing corrugated oil box 10kV distribution transformer are described in further details.
As shown in Figure 1, the utility model 800kVA and above Full-sealing corrugated oil box 10kV distribution transformer, comprise transformer body 1, be positioned at the sealing corrugated tank 2 of transformer body 1 side and be positioned at the Buchholz relay 3 of transformer body 1 top, above transformer body 1, be provided with oil-level gauge base 4, above oil-level gauge base 4, be provided with tube connector 5, above tube connector 5, be provided with oil-level gauge 6.The upper end of tube connector 5 is higher than the upper surface of Buchholz relay 3.The transformer oil of annotating above tube connector 5, after filling it up with, is arranged on tube connector 5 tops by oil-level gauge 6.Like this, can guarantee to be full of oil in the grease chamber of Buchholz relay, making case change rear box height reduces greatly, reduced casing cost, casing carrying is more convenient, for the copper bar of connection transformer and low pressure only need get around tube connector and oil-level gauge and with its maintenance insulation distance, can greatly shorten copper bar length.
Tube connector 5 can be as shown in Figure 1 cylindric.Also can be as shown in Figure 2, tube connector 5 comprise be arranged in upper end upper connecting leg 51, be arranged in the ball-type tripe 52 and the lower connecting leg 53 that is positioned at these ball-type tripe 52 belows and is connected with oil-level gauge base 4 of connecting leg 51 belows, can many splendid attires transformer oil in tripe 52 in the ball-type of tube connector, solved because expanding with heat and contract with cold or because consuming the too low problem of pasta that causes.
As shown in Figure 3, lower connecting leg 53 is serpentine bend pipe, in the situation that highly not increasing, has further improved oily total amount.
Protection range of the present utility model is not only confined to above-described embodiment, as long as structure is identical with the structure of the utility model 800kVA and above Full-sealing corrugated oil box 10kV distribution transformer, just drops on the scope of the utility model protection.
