High-voltage switch cabinet capable of changing position of grounding switch and position of current transformer

Abstract

The invention provides a high-voltage switch cabinet capable of changing the position of a grounding switch and the position of a current transformer, and relates to the technical field of switch cabinets. The high-voltage switch cabinet is used as a distribution device for receiving or distributing power supplies. A bus chamber, a breaker chamber and a cable chamber are arranged on the upper portion in the switch cabinet, wherein the breaker chamber is located on one side of the bus chamber, the cable chamber is located below the bus chamber, bus bars are installed in the bus chamber, and an incoming and outgoing cable is led out of the cable chamber. The current transformer is installed below the bus chamber. A lower partition plate is arranged in the cable chamber. An operating shaft is installed below the breaker chamber, part of the operating shaft is located in the cable chamber, and the part, located in the cable chamber, of the operating shaft is connected with the grounding switch which is transversely and vertically installed on the lower partition plate. By the adoption of the high-voltage switch cabinet, electric clearance between the grounding switch, the current transformer and the outgoing cable is increased, safety of the electric clearance is higher, and space is more reasonable after the installing positions of elements of the cable chamber are changed.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a high-voltage switch cabinet for changing the position of a grounding switch and a current transformer. Background technique [0002] The electrical clearance in the high-voltage switchgear will directly affect the product quality of the high-voltage equipment. In addition to the quality of the components selected, another important factor for the product quality of the high-voltage switchgear is the electrical clearance. There are special standards for electrical clearance in the country, and it is a high standard that is greater than the national standard. Increasing the electrical clearance while the size of the shell remains unchanged is always the direction of switch cabinet manufacturers. Larger electrical clearances are conducive to the stability of product quality. Equipment Maintenance and repair after operation should be convenient. High-voltage power distribu...

AI Technical Summary

Problems solved by technology

The installation of the position of the grounding switch and the position of the current transformer is inconvenient for production, on-site operation and later maintenance, and the internal electrical clearance is small, which is not conducive to heat dissipation of components
