Description

Technical Field

[0001] The utility model belongs to the technical field of high-voltage switch cabinets, and in particular relates to a grounding structure of a high-voltage switch cabinet. Background Art

[0002] High-voltage switchgear refers to electrical products with voltage levels ranging from 3.6kV to 550kV, which are used for switching, control or protection in power generation, transmission, distribution, power conversion and consumption in power systems. They mainly include high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switchgear.

[0003] High-voltage switchgear usually generates a large amount of static electricity during its use, so a grounding structure needs to be installed at the bottom of the cabinet to dissipate the static electricity. However, conventional grounding structures can usually only dissipate the static electricity of the device itself. Some outdoor high-voltage switchgear may sometimes be struck by lightning. Conventional grounding structures cannot dissipate the electricity caused by lightning, and conventional grounding structures are not strong enough after being installed underground, and may be damaged when encountering a large electric shock. For this reason, we propose a grounding structure for high-voltage switchgear. Utility Model Content
