Grounding system applied to high-voltage switch cabinet and processing method thereof

Abstract

The invention discloses a grounding system applied to a high-voltage switch cabinet and a processing method thereof. The grounding system comprises a trolley grounding bar, a contact box mounting plate, a left rear side plate and a bottom plate, wherein the contact box mounting plate and the left rear side plate are adjacently arranged and vertically installed together, the contact box mounting plate, the left rear side plate and the bottom plate are installed in a mode of being vertical with each other; opposite positions of the trolley grounding bar and the contact box mounting plate are provided with regular hexagon shaped holes used for fixedly installing a first grounding bar, the left rear side plate is provided with two bosses so as to be convenient for fixedly installing a second grounding bar, the bottom part of the left rear side plate is provided with a third grounding bar, and the bottom plate is provided with a first main grounding bar and a second main grounding bar. The grounding system with the structure disclosed by the invention for the high-voltage switch cabinet and the processing method thereof enables the grounding system to be normalized, standardized and humanized through normalizing mounting positions and fixing modes of the components, thereby improving the production efficiency and the product grad and quality, and enabling the space to be larger and safer.

Description

technical field [0001] The invention relates to a metal-clad removable high-voltage switchgear, in particular to a grounding system for the metal-clad removable high-voltage switchgear and a processing method thereof. Background technique [0002] At present, in the power system, most of the armored removable AC enclosed switchgears used in the KYN28A-12 high-voltage switchgear are equipped with a relatively complex grounding system. The system is random in the production process, and when there is no exact installation position for assembly, It often varies from person to person, resulting in obvious shortcomings of non-standard and non-standard. The system has relatively few fixed positions, which reduces its reliability, and because the grounding bar is installed against the rear side panel, the safety distance from the branch busbar is reduced, and there are certain safety hazards during use. Contents of the invention [0003] The technical problem to be solved by the...
