[0002] A gas-filled cabinet is a switchgear filled with a certain gas as an insulating medium, such as sulfur hexafluoride gas or environmentally friendly nitrogen. It is a high-voltage switchgear generally used in important distribution rooms and other scenarios. Most of the current gas-filled cabinets are integrated, and the elbow entry method is generally the bottom entry method. There is a problem of small space from the bottom of the ground and inconvenient cable connection. In addition, the grounding bar needs to be set at the bottom to cooperate with the bottom entry, and needs to be fixed and installed separately. For cable insulation, it is often necessary to add an auxiliary cabinet gas bag. The gas bag is filled with sulfur hexafluoride, which has the factor of gas leakage. Under the action of arc and corona, sulfur hexafluoride gas will decompose to produce low-fluorine compounds. These compounds will cause damage to the insulating material. These low-fluorine compounds are highly toxic gases, which are not conducive to environmental protection and are expensive. Utility Model Content
