Description

Technical Field

[0001] The present invention relates to the technical field of ring main unit (RMU), and in particular to an environmentally friendly and safe gas ring main unit (RMU). Background Art

[0002] A ring main unit (RMU) refers to an electrical device that uses a load switch for circuit control and is an assembled interval-type ring main unit. It is mainly used to control each branch line in the ring main system, and plays the role of distribution and opening and closing. The environmentally friendly gas RMU uses dry air or nitrogen as an insulating medium, which can reduce the emission of sulfur hexafluoride and reduce the impact of greenhouse gases on the atmosphere. However, the existing environmentally friendly gas RMU has a simple heat dissipation structure and it is difficult to adjust the position of the cooling fan, which affects the heat dissipation performance of the RMU. At the same time, the load switch running during the use of the RMU will resonate with the RMU, which will generate noise during resonance, thereby affecting the user's experience. In addition, the load switch of the RMU and the external sleeve are mostly spot-welded, which affects the connection stability of the load switch and the external sleeve, thereby reducing the practicality of the equipment. Therefore, it is very necessary to design an environmentally friendly and safe gas RMU. Summary of the Invention
