Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment of the transformer of the utility model, as shown in Figures 1 to 4, transformer include transformer body, are become
Depressor main body includes iron core 1, high-tension coil 5 and low-voltage coil 4, leads to high pressure master respectively from high-tension coil 5 and low-voltage coil 4
Lead 7 and low-voltage lead 10, the main lead 7 of high pressure pass through low-voltage terminal 6 by bushing 9 and external connection, low-voltage lead 10
With external connection.Coil in the present embodiment is arranged side by side, and coil is respectively transformation in the horizontal two sides perpendicular to direction side by side
The high-pressure side of device and low-pressure side.As shown in Figure 1, HV Terminal uses bushing, bushing 9 and the setting of low-voltage terminal 6 exist
