Description

Ring main unit external hanging operation device and ring main unit structure Technical Field The application relates to the technical field of electric power operation devices, in particular to a ring main unit external hanging operation device and a ring main unit structure. Background With the development of electric power technology, a ring main unit technology appears, and the ring main unit is a high-voltage switch device for a ring distribution network, a power supply trunk forms a closed ring, and each distribution branch can take power from two sides of the trunk. If one side fails, the other side automatically switches power supply, so that the effect similar to double-path power supply is realized, the reliability of power supply can be improved, and the ring main unit is widely applied to power supply and distribution links of urban power grids, industrial parks, markets and the like. In the related art, an operation hole is usually formed in one side of the ring main unit, when the ring main unit is required to be operated, an operation handle is inserted into the ring main unit through the operation hole, the end part of the operation handle is connected with an interface of a switching device in the ring main unit in a matched mode, and at the moment, the operation handle is rotated to adjust the switch of the ring main unit. The operation is performed manually, so that the ring main unit is electrified, a plug-in device is arranged at present, part of the structure of the plug-in device is directly connected with an interface of a switch device in the ring main unit, and the switch of the ring main unit is directly controlled in an electric driving mode. However, the existing ring main units are different in brands and use scenes, and usually have multiple types or specifications, interfaces at the switch device of the ring main units with different types or specifications and distances from the interfaces at the switch device to the operation holes are different, the existing external hanging devices are usually designed according to ring main units with specific types, and for ring main units with different types, the external hanging devices cannot be connected for use due to mismatching of the interfaces or inappropriate structural lengths of parts connected with the interfaces, and redesign, mold opening and production of the external hanging devices are required according to the shapes of the interfaces at the switch device of the ring main units and the distances from the interfaces at the switch device to the operation holes.
