Pouring bus groove

Abstract

The invention discloses a casting bus slot; the end surface of the casting isolator 1 of the bus is provided with a dovetail groove 2; a body part is provided with a step-shaped structure 6. During field connection and mounting, a method of secondary casting is adopted for realizing the connection between two buses; a secondary casting isolating block 4 forms a wedge-shaped structure 5 inside the dovetail groove 2 at the end surface of the casting isolator of the bus; simultaneously the step-shaped structure 6 in the body part forms a baffle block in the secondary isolating block to lead the secondary casting isolating block 4 to be closely connected with the casting isolator 1 of the bus. A splicer 8 is arranged inside the secondary casting isolating block 4 to realize the connection of the mother bar of a phase line; when a casting bus slot is fixed and mounted, the step-shaped structure 6 in the body part of the casting isolator 1 of the bus is simultaneously used as the limiting block for fixing and mounting the bus. When the casting bus slot is during double-slot type mounting, the step-shaped structure in the body part of the casting isolator 1 of the bus is combined into a drain slot to prevent water accumulation on the upper surface of the casting bus.

Description

technical field [0001] The invention relates to a cast bus duct in power transmission and distribution facilities. Background technique [0002] In the prior art, power transmission and distribution facilities generally use high-strength insulating bus ducts or ordinary cast bus ducts. Although the high-strength insulating bus ducts are firmly connected, the highest protection level is IP54, which cannot be waterproof, fireproof, anti-corrosion, or explosion-proof. When ordinary cast bus ducts are used, they cannot be connected by fasteners. The use of a packaged structure will cause thermal expansion and contraction due to changes in the environment and temperature. The joints are prone to slipping, and it is difficult to locate and fix during installation. Ordinary resin is used as the casting material, which cannot meet the requirements of fire protection and anticorrosion, and is not suitable for special occasions such as thermal power, chemical pollution, and fire-resis...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, power transmission and distribution facilities generally use high-strength insulating bus ducts or ordinary cast bus ducts. Although the high-strength insulating bus ducts are firmly connected, the highest protection level is IP54, which cannot be waterproof, fireproof, anti-corrosion, or explosion-proof.

However, ordinary cast bus ducts cannot be connected with fasteners when in use. The use of a packaged structure will cause thermal expansion and contraction due to changes in the environment and temperature, and the joints are prone to slipping, and it is difficult to locate and fix during installation.

The casting material is made of ordinary resin, which cannot meet the requirements of fire protection and anticorrosion, and is not suitable for special occasions such as thermal power, chemical pollution, and fire-resistant trunk power distribution.

[0003] In the prior art, the upper surface of ordinary pouring busway is easy to cause water accumulation, especially in double-slot busway
