Abstract
The utility model provides a box-type substation transformer low pressure side wiring structure, low pressure side wiring board at box-type substation transformer passes through the bolt and is connected with the lower part link of copper flexible coupling, the upper portion link of copper flexible coupling passes through the bolt and is connected the female link of arranging of low tension switchgear, the advantage is, install copper flexible coupling between the female arranging of low pressure side wiring board and low tension switchgear of box-type substation transformer, the wiring board of the transformer that equipment appears in the transportation warp, insulating vase fracture or the not hard up problem of insulating vase fixed point, the potential safety hazard of equipment operation has been eliminated, the fail safe nature of equipment operation has been improved.
Description
Technical Field
The utility model relates to a box-type substation transformer low pressure side wiring structure.
Background
The transformer is widely applied to various transformer substation places, the low-voltage side of the transformer substation, namely the 0.4 KV side, is connected with a low-voltage switch cabinet, the existing two connection modes, namely busbar connection or low-voltage cable connection, are adopted, and the busbar connection is mostly adopted in consideration of the cost and the manufacturing process. The wiring board of transformer low pressure side directly adopts four bolts to be connected with female junction of arranging, this kind of connected mode drawback: one condition is that the wiring board of the transformer is stressed to cause deformation or cracking of an insulating porcelain insulator due to bumping in the transportation process; the other situation is that the vibration of the transformer during operation causes the fixed point of the porcelain insulator to become loose, which causes potential safety hazard and influences the stability and reliability of operation.
Disclosure of Invention
An object of the utility model is to solve the above-mentioned current problem that exists, provide an improve operational reliability's box-type substation transformer low pressure side wiring structure.
The utility model discloses a realize like this: the low-voltage side connection board of the box-type transformer substation is connected with the lower connecting end of the copper flexible connection through the bolt, and the upper connecting end of the copper flexible connection is connected with the connecting end of the busbar connected with the low-voltage switch cabinet through the bolt, so that flexible connection between the low-voltage side connection board of the box-type transformer substation and the low-voltage side busbar of the low-voltage switch cabinet is achieved.
The utility model has the advantages that, at box-type substation transformer's low pressure side wiring board and low-voltage switchgear's female arranging between installation copper flexible coupling, the wiring board of having solved the transformer that equipment appears in the transportation warp, insulating vase fracture or the not hard up problem of insulating vase fixed point, has eliminated the potential safety hazard of equipment operation, has improved the fail safe nature of equipment operation.
