Abstract
A high-voltage wire inlet and wire outlet structure of an underground transformer is characterized in that the structure comprises cable junction sockets fixed on a cover of a transformer fuel tank, a front plug-pull type separable cable joint inserting in the cable junction sockets, a rear inserting type separable cable joint inserting in the front plug-pull type separable cable joint, a high-voltage wire inlet and wire outlet cable connected with the front plug-pull type separable cable joint, another high-voltage wire inlet and wire outlet cable connected with the rear inserting type separable cable joint, and a high-voltage lead-in wire connected on the cable junction sockets and located inside the transformer fuel tank. Compared with the prior art, the underground transformer high-voltage wire inlet and wire outlet structure in the utility model has the advantages of advanced technology, simple compact structure, easy installing operation, low technical requirement and excellent waterproof performances. Furthermore, the structure can satisfy the waterproof functional requirements of underground transformers without any additional waterproof measure after connected.
Description
Technical field
The utility model relates to a kind of subway transformer.
Background technology
At present the subway transformer high pressure into and out of line Bian with two kinds of organization plans.The one, with (American) plug-in elbow type cable joint and receptacle combinations thereof.Another is with three-phase integrated plug-in cable connector.Plug-in elbow type cable joint and receptacle combinations thereof are by the design of ground electric equipment service condition and make that its water resistance is poor, and is not suitable for the environment for use and the requirement of underground transformer.Shi Yong Time also need take other auxiliary waterproof measure Jia Yi Fill to rescue.High-pressure side requires Jin Chu Xian Time, and the socket of six elbow type cable joints is installed on case lid or casing side, takies the area of very big a slice like this, causes very big difficulty for the little underground transformer structural configuration of capacity.The cable junction that doubles in addition, but product breakthrough and unsafe factor also double, product cost also increases.Three-phase integrated plug-in cable connector biggest advantage is San Xiang Tong Time plug, but the complex structure of this connector own is bulky.Plug and cable assembling complex process, the loose contact phenomenon appears in specification requirement height easily.This cable connector is for guaranteeing the waterproof sealing reliability of cable and connector plug and connector plug and socket, will be at the above-mentioned local marine glue of placing, material such as mackintosh and heat-shrink tube carries out encapsulation process, complex process, the construction trouble, the specification requirement height seepage occurs in a little places easily.Employing brings great trouble and inconvenience for the plug of cable connector after getting these measures, and promptly all seal approach of Cha Ba Time are with destroyed.
Summary of the invention
Goal of the invention of the present utility model is to provide that a kind of mounting process is simple, installation specification is low, favorable waterproof property arranged, connect after, the waterproof measure that need add just can not satisfy subway transformer high pressure that the water-proof function of underground transformer requires into and out of line structure.
The utility model is to realize like this, comprise the cable gang socket that is fixed on the oil tank of transformer case lid, be inserted in the preceding plug-in separable cable joint in the cable gang socket, rear loading type separable cable joint before being inserted on the plug-in separable cable connection joint, the height that is connected with preceding plug-in separable cable joint is compressed into line ∕ outlet (inlet wire/outlet of transformer external high pressure) cable, the height that is connected with rear loading type separable cable joint extrudes line ∕ inlet wire (transformer external high pressure outlet/inlet wire) cable, and the oil tank of transformer inner high voltage lead-in wire that is connected in the cable gang socket is formed.The cable gang socket that the utility model adopted, preceding plug-in separable cable joint, its technology maturation of rear loading type separable cable joint, dependable performance, but long-term work is under water, and preceding connection-peg is as the transformer high-voltage inlet wire.Yao Qiu Time if any high-voltage terminal, only need on preceding plug-in separable cable joint, plug rear loading type separable cable joint (rear loading type separable cable joint is connected with high-voltage terminal).If need high pressure Duo road Shu Chu Time, only need on preceding connection-peg, to insert a plurality of rear loading type joints and get final product.Also have only three socket positions on the Zhe Time underground transformer case lid.This plug, functional, socket is an all insulation type full-closed structure, the tight Minato of structure, required installation site is little.Characteristics are that cable and plug mounting process are simple, and specification requirement is low, Hen Yi Full foot.Plug is connected also simple with socket, and favorable waterproof property is arranged, and the waterproof measure that need not add after the connection just can satisfy the requirement of underground transformer environment for use and water-proof function
The utility model is compared with the structure of present employing, advanced technology, tight Minato simple in structure, installation is simple, specification requirement is low and favorable waterproof property is arranged, advantage that water-proof function that the waterproof measure that need not add after connecting just can satisfy underground transformer requires.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model comprises by pressing plate 10, is welded in the screw rod 11 on the case lid 1, nut 12, and seal washer 13 is fixed on three cable gang sockets 2 on the oil tank of transformer case lid 1.The preceding plug-in separable cable joint 3 that is connected with cable gang socket 2, the rear loading type separable cable joint 4 that is connected with preceding plug-in separable cable joint 3.Adopt the height of pressing connected mode and preceding plug-in separable cable joint 3 to link together to compress into line ∕ outlet cable (transformer external high pressure inlet wire/outlet cable) 5.Adopt the height of pressing connected mode and rear loading type separable cable joint 4 to link together to extrude line ∕ inlet wire (transformer external high pressure outlet/inlet wire) cable 6.By bolt 14, packing ring 15, spring washer 16 are connected the oil tank of transformer inner high voltage lead-in wire 7 in the cable gang socket 2.
Claims (1)
1. a subway transformer high pressure is into and out of line structure, it is characterized in that comprising the cable gang socket that is fixed on the oil tank of transformer case lid, be plugged on the preceding plug-in separable cable joint in the cable gang socket, rear loading type separable cable joint before being plugged on the plug-in separable cable joint, compress into line ∕ outlet cable with the height that preceding plug-in separable cable joint links together, the height that links together with rear loading type separable cable joint extrudes line ∕ inlet wire cable, is connected the oil tank of transformer inner high voltage lead-in wire in the cable gang socket.
