[0007] In order to facilitate the disassembly and assembly of the bushing assembly, in a preferred embodiment of the present invention, the bushing assembly includes a connector, a bushing and a guide tube. One end of the connector is inserted into the mounting hole and electrically connected to the reactor or transformer lead. The other end of the connector is arranged in the protective outlet box. The bushing is sleeved on the other end of the connector and is detachably connected to the connector. The bushing is parallel to the horizontal plane. The guide tube is perpendicular to the bushing and is integrally formed with the bushing. One end of the guide tube is connected to the inner cavity of the bushing, and the other end extends to the outside of the protective outlet box.
[0008] In order to ensure the stability of the guide tube, an outlet for the guide tube to be plugged in is provided at the bottom end of the protective outlet box.
[0009] Preferably, the protective outlet box and the sealing plate are detachably connected or welded.
[0010] In order to facilitate the installation and maintenance of the interior of the protective outlet box, a mounting plate is detachably mounted on one end of the protective outlet box away from the sealing plate.
[0011] The beneficial effects of the utility model are as follows: the reactor or transformer with a safety protection mechanism of the utility model has low requirements for environmental pollution, and no electric shock accidents will occur when people touch any position of the outer surface of the reactor or transformer body. It has high operational safety and is simple to install and convenient for long-distance transportation. The product has a high accessory value, which will not only bring certain social value, but also improve product competitiveness and bring certain economic value to the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS
