AI Technical Summary

Problems solved by technology

Once the sealing performance of the joint connection device of the busbar housing fails to meet the protection level requirements, rainwater and dust will enter, the insulation performance of the busbar will be reduced, the busbar will be short-circuited, and the entire power supply system will be paralyzed, so that the power supply cannot keep up with the needs of the society.

Abstract

The invention provides a connection device for high voltage shared-case enclosed busbar shell connectors. The connection device comprises a pair of angle aluminum 7 and Z-shaped angle aluminum profile 5 which are matched with each other. The angle aluminum 7 is fixed to the edge of a left-section high voltage shared-case enclosed busbar shell 1, and the Z-shaped angle aluminum profile 5 is fixed to the edge of a right-section high voltage shared-case enclosed busbar shell 2. The upper edge of the angle aluminum 7 is lower than the upper portion of the Z-shaped angle aluminum profile 5 when the angle aluminum 7 and the Z-shaped angle aluminum profile are arranged in a matched mode. Two side-by-side grooves are formed in the matching surface of the Z-shaped angle aluminum profile 5, sealing strips 6 are embedded in the grooves, and the angle aluminum 7 and the Z-shaped angle aluminum profile 5 are matched and then are closely connected through a fastening piece.

Description

technical field [0001] The invention relates to a joint connection device for a high-voltage common box closed bus bar shell. Background technique [0002] In the prior art, "L" type double-angle aluminum flanges are used for the shell connection between the closed busbar sections of the common box, and the middle gasket is fixed with bolts. The gasket between the flanges is exposed, and it is easy to age under the wind and rain, which will cause rainwater to infiltrate and cause safety accidents. If the original shell connection structure is installed outdoors, a rainproof cover must be installed outside the connection device to prevent rainwater from infiltrating. Its production process is complex, the cost is high, and the installation is not beautiful. At the same time, the original connecting device requires four sealing gaskets to be drilled with the flange surface, which makes the installation complicated. [0003] In the prior art, the airtightness of the connecti...
