Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of low-voltage lead structure of dry-type transformer, this low-voltage lead structure can make lead-in wire easy, reduce cost, thereby solve the baroque problem of conventional wire.
The purpose of this utility model is achieved by the following technical solution:
A kind of low-voltage lead structure of mining dry-type transformer, comprise transformer body, low-voltage coil, connection guide rod, insulator, terminal block and conductive copper bus, insulator is fixed on one's body the transformer, one end of conductive copper bus is fixed on the insulator by connecting guide rod, the other end is connected with low-voltage coil, it is characterized in that: the number of plies of described low-voltage coil is an even level, and the advancing head and lift one's head all at the upside of low-voltage coil and be positioned on the terminal block of top, transformer body side of low-voltage coil.
Insulator is by being bolted on one's body the transformer in the utility model.
Connect by brace between the binding post on the utility model terminal block.Brace is fixed on copper nut, copper backing and connects on the guide rod.Brace is adjusted outlet method, and brace can connect by output voltage according to actual needs.
The conductive copper bus is a TMY high-quality rigid copper bus in the utility model.
The utility model is placed on the low-voltage lead position upper end of transformer body middle part, the low-voltage coil number of plies is designed to even level, advance head and lift one's head all upside at coil, only the head that advances of coil all need be caused on the terminal block on b phase coil top, device body side with lifting one's head during lead-in wire, Y (star-like)-D (triangle) conversion is convenient freely.Compared with prior art, the utlity model has following advantage: solved conventional low pin configuration complexity and copper consumption is bigger, increase the length of housing, caused low-voltage direct resistance imbalance, the problem that cost is big.
