Abstract
The utility model provides low-voltage leads of an oil-immersed transformer. The low-voltage leads are connected with head ends and tail ends of a plurality of low-voltage coils. The low-voltage leads comprise a plurality of cables and lug plates capable of being detachably and electrically connected with one ends of the cables. Body original wires are led out of the head ends and the tail ends of the low-voltage coils. One ends of the cables are electrically connected with the body original wires. The low-voltage leads of the oil-immersed transformer are convenient to operate, simple in structure, low in cost and free of welding pollution.
Description
Technical field
The utility model relates to the power transmission and transformation technical field, particularly a kind of oil-filled transformer low-voltage lead.
Background technology
In oil-filled transformer, the transformer low voltage lead-in wire is connected the two ends of low pressure winding, uses copper bar as lead-in wire usually, draws and introduces low-tension bushing again after weld with lug plate the back.This Welding Structure is owing to need carry out operation inconvenience in the smaller transformer of space; The spark that produces during welding is splashed on the Transformer Winding easily, influences its operate as normal, and in addition, producing a large amount of harmful substances during welding also has bigger pollution to environment.
The utility model content
The purpose of this utility model is to propose a kind of handled easily, simple in structure and do not have an oil-filled transformer low-voltage lead that welding is polluted.
For achieving the above object, the utility model proposes a kind of oil-filled transformer low-voltage lead, be connected in the two ends of a plurality of low-voltage coils, the lug plate that described low-voltage lead comprises a plurality of cables and detachably is electrically connected on described cable one end, the two ends of described a plurality of low-voltage coils lead to the former lead of body, and described cable one end is electrically connected on the former lead of described body.
Further, in above-mentioned oil-filled transformer low-voltage lead, described a plurality of low-voltage coil is four, described a plurality of cable also is four, the tail end of four low-voltage coils is electrically connected on a cable by the former lead of body, and the head end of described four low-voltage coils is electrically connected on three cables in addition by the former lead of body respectively.
Further, in above-mentioned oil-filled transformer low-voltage lead, be connected with the lead fishplate bar on described a plurality of cables.
Further, in above-mentioned oil-filled transformer low-voltage lead, described cable adopts the bolt mode to fixedly connected with lug plate.
The utility model oil-filled transformer low-voltage lead handled easily, simple in structure, cost is low and do not have welding and pollute.
Description of drawings
Fig. 1 is the structural representation of the utility model oil-filled transformer low-voltage lead one embodiment.
Fig. 2 is the connection diagram of Fig. 1 mesolow lead-in wire with low-voltage coil.
Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, the utility model oil-filled transformer low-voltage lead, it is connected in the two ends of a plurality of low-voltage coils 1, described low-voltage lead comprises a plurality of cables 2 and the lug plate 3 that detachably is electrically connected on described cable 2 one ends, the two ends of described a plurality of low-voltage coil 1 lead to the former lead 12 of body, and described cable 2 one ends are electrically connected on the former lead 12 of described body.
Wherein, be connected with lead fishplate bar 4 on described a plurality of cables 2, be used for fixing described a plurality of cables 2.
Described a plurality of low-voltage coil 1 is four, described a plurality of cable 2 also is four, the tail end of four low-voltage coils 1 is electrically connected on a cable 2 by the former lead 12 of body, and the head end of described four low-voltage coils 1 is electrically connected on three cables 2 in addition by the former lead 12 of body respectively.
Described cable 2 can adopt the bolt mode to fixedly connected with lug plate 3, namely wears cable 2 and lug plate 3 by the bolt (not shown), thereby cable 2 is fixedlyed connected with lug plate 3.
Than prior art, the utility model oil-filled transformer low-voltage lead directly is electrically connected on low-voltage coil and low-tension bushing by the former lead of the body of low-voltage coil, need not to descend again copper bar welding and wrapping like this, improved the low-voltage lead operating efficiency, reduced raw materials consumption, reduced welding and polluted.
The utility model oil-filled transformer low-voltage lead handled easily, simple in structure, cost is low and do not have welding and pollute.
Here description of the present utility model and application is illustrative, is not to want with scope restriction of the present utility model in the above-described embodiments.Here the distortion of disclosed embodiment and change is possible, and the various parts of the replacement of embodiment and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation that does not break away from spirit of the present utility model or substantive characteristics, and the utility model can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.Under the situation that does not break away from the utility model scope and spirit, can carry out other distortion and change to disclosed embodiment here.
