Secondary terminals are separately connected into and out of line cable and realize sealed insulation, this kind of volume of transformer by casting insulated waterproof material
It is huge, it is not easy transport and internal wiring setting is complicated；On the other hand, end is wired to be difficult to carry out subsequent inspection after sealed cast
It repairs, and insulative water-proof material has not met environmental protection standard now, so, Covered transformer need to further be studied and be changed
Into.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of portable construction, is easy to overhaul and leakproofness is good
Good Covered transformer.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of Covered transformer, including transformer body are provided with connection inlet wire cable in the transformer body
High-voltage connecting electricity end seat and the low-voltage power supply end seat for connecting outlet cable, sealing welding is connected to sealing on the transformer body outer wall
Case, the high-voltage connecting electricity end seat and low-voltage power supply end seat are arranged in seal box, are provided on the seal box for electric into and out of line
The incoming line and line outlet connect is worn in cable sealing, is additionally provided with access hole on the seal box.
Inlet wire cable sealing device is provided at the incoming line comprising cable flange A, cable rubber mat A, cable flange
B, cable flange C, cable rubber mat B and cable flange D.
It is outer that outlet cable sealing inner flange, outlet cable seal gasket and outlet cable sealing are provided at the line outlet
Flange.
The access hole will maintenance by access hole sealing flange, access hole seal gasket and the cooperation of access hole seal cover board
Mouth blocks.
The beneficial effects of the utility model are: the Covered transformer of the utility model has abandoned previous thick and heavy cabinet,
Directly sealing welding is connected to seal box on transformer body, is connected to wearing on seal box into and out of the sealing of line mouth into and out of line cable
Connect and in seal box high-voltage connecting electricity end seat and low-voltage power supply end seat realization be electrically connected, no longer need to casting insulated waterproof material into
Row sealing, while seal box has access hole, it is convenient that maintenance and inspection are carried out to the route in seal box in the future.
