Because it is immersed in oil, the volume of the components is greatly reduced, the structure is more compact, and the installation is convenient and flexible. Fully insulated, fully sealed structure, safe and reliable, easy to operate, maintenance-free. Widely used in residential areas, high-tech centers, factories and mines, airports, stations, schools and other places.

[0003] The high-voltage side load switches of the existing old-style American box transformers are all manually operated. An epoxy resin insulating rod is inserted into the hole on the transformer shell, and the high-voltage load switch operating rod is twisted and rotated manually to achieve the function of connecting and disconnecting the high-voltage load switch. This method has many disadvantages, such as: it cannot be remotely operated to realize the remote control function required by the distribution network automation, and the operator must be required to operate facing the high-voltage switch equipment. If a fault occurs during the operation, there will be a great safety hazard, which will endanger the life safety of the operator. Utility Model Content
