Description

Technical Field

[0001] The utility model relates to an environmentally friendly gas-insulated PT cabinet. Background Art

[0002] An environmentally friendly gas-insulated PT cabinet is a voltage transformer cabinet using an environmentally friendly gas as an insulating medium. Compared with a traditional PT cabinet using SF6 (sulfur hexafluoride) gas, the environmentally friendly gas-insulated PT cabinet adopts an insulating gas that is more friendly to the environment to reduce the negative impact on the environment. Generally, an environmentally friendly gas-insulated PT cabinet includes a switch cabinet room, a pressure relief cabinet room, an instrument cabinet room, a mechanism cabinet room and a cable cabinet room. The mechanism cabinet room is provided with a handle operation hole for inserting an operation handle. There is no protection at the handle operation hole in the existing mechanism cabinet room, and it is relatively easy for personnel to operate the PT cabinet. Moreover, since the environmentally friendly gas-insulated PT cabinet is relatively large, when there are personnel operating or maintaining at the rear of the PT cabinet, the operation handle can still be inserted for operation, with poor interlocking performance, and there are potential operation safety hazards in the entire PT cabinet.
