Example Embodiment

[0023] Example one: such as figure 1 As shown, the outer surface of the voltage transformer body 1 is provided with epoxy resin 5, and the inside of the epoxy resin 5 is provided with a metal shielding mesh 10, and the voltage transformer body 1, the epoxy resin 5 and the metal shielding mesh 10 are casted Sealed and molded, it can increase the protection level, the protection level is up to IP67, and the equipment can work normally under water for at least 30 minutes; it can be put into operation normally after being immersed in water, and it can realize safe touch function.

Example Embodiment

[0024] Embodiment two: such as figure 1 As shown, a fixing screw is arranged between the secondary junction box 6 and the voltage transformer main body 1, and the outer surface of one side of the secondary junction box 6 is fixedly connected with the outer surface of the voltage transformer main body 1 through the fixing screws. 3 Poured inside the epoxy resin 5, a connecting wire is arranged between the voltage transformer body 1 and the primary conductor 4. One end of the voltage transformer body 1 is electrically connected to one end of the primary conductor 4 through the connecting wire, and the voltage transformer body Bolts are arranged between 1 and the mounting aluminum plate 2. The upper end of the voltage transformer body 1 is fixedly connected to the lower end of the mounting aluminum plate 2 through bolts, which is more convenient for installation and disassembly, the connection is more stable, and it is not easy to fall off, which is convenient for people to use .
