Abstract
The utility model relates to an arrangement structure for a transformer low voltage y connection lead. The arrangement structure belongs to an arrangement method for the transformer lead and comprises a low voltage lead clamp and a low voltage copper bar. The arrangement structure is characterized in that a low voltage neutral point lead of the transformer is led out between two phases of a and b. The arrangement structure can ensure resistance unbalance of a low voltage wire end, meanwhile saves the low voltage copper bar, and is simple in structure, convenient to operate, safe, reliable, and attractive in wire shape. The arrangement structure can reduce material use quantity, improves operation performance of the transformer, and is mainly applied to a 35-220kV-grade power transformer.
Description
(1) field under
The utility model relates to the arrangement that a kind of transformer low voltage y connects lead-in wire, belongs to field transformer.
(2) backgroundTechnology
Present stage, 35～220kV level power transformer low pressure is y when connecing, and the underproof phenomenon of low resistance unbalance factor is often arranged, in this case, for guaranteeing that the low resistance unbalance factor reaches reasonable value, needing increases the low-voltage copper bar size, has increased material consumption and takes up room.
(3) inventionContent
In order to remedy the deficiencies in the prior art, the utility model provides a kind of transformer low voltage y attractive in appearance simple in structure, easy to operate, safe and reliable, linear to connect the arrangement of lead-in wire.
The technical solution of the utility model is:
A kind of transformer low voltage y connects the arrangement of lead-in wire, comprises low-voltage lead folder, low-voltage copper bar, it is characterized by: the low pressure neutral point lead-in wire of transformer is by drawing between a, the b two-phase.
The beneficial effects of the utility model are: the low pressure neutral point lead-in wire of the utility model transformer is by drawing between a, the b two-phase, can be convenient to guarantee low pressure line end resistance unbalance rate, saved low-voltage copper bar simultaneously, simple in structure, easy to operate, safe and reliable, linear attractive in appearance; It can reduce material usage, improves the transformer runnability, mainly is applicable to 35～220kV level power transformer.
