Description

Technical Field

[0001] This utility model relates to the field of busbar installation technology, specifically a slot structure used for clamping busbars. Background Technology

[0002] Applications of busbars: They are mainly used in my country's power construction projects as conductors connecting power transmission lines and substation transformers, jumpers in transmission lines, connecting conductors in power equipment, and as current conductors in high-current DC de-icing devices. They are a new type of conductor that replaces traditional rectangular, trough, rod-shaped busbars and flexible conductors. They are one of the key devices in power transmission and transformation systems and play a vital role in the safe and reliable operation of power transmission and transformation systems and power equipment. When existing busbars are installed inside busbar troughs, they are usually placed in slots in the inner wall of the busbar trough. Because there is no structure to fix the busbar, it is easy for the busbar to slide inside the slot, making the busbar installation unstable. Utility Model Content
