Description

Technical Field

[0001] The utility model belongs to the technical field of busbar installation, and in particular relates to a busbar installation bracket. Background Art

[0002] Purpose of busbar: It is mainly used in the conductor connection between power grid transmission wires and substation transformers in my country's power construction projects, jumpers in transmission lines, connecting conductors in power equipment, and as overcurrent conductors in large current DC ice melting devices. It is a new conductor that replaces traditional rectangular, trough, rod-shaped busbars and soft wires. It is one of the key equipment (materials) in the power transmission and transformation system, and plays a vital role in the safe and reliable operation of the transmission and transformation system and power equipment.

[0003] At present, most of the existing busbar mounting brackets do not have the function of buffering and shock absorption. When vibrated by the external environment, the vibration of the busbar will drive the mounting bracket to vibrate, resulting in an unstable installation, which is not conducive to the stable use of the busbar. For this reason, we propose a busbar mounting bracket. Utility Model Content

[0024] Specifically, knobs 4 are provided at the bottom of the adjusting screw 3 and the fastening screw 13 , and the knobs 4 are fixedly connected to the adjusting screw 3 and the fastening screw 13 , respectively.

[0025] Specifically, the inner wall surfaces on both sides of the buffer seat 8 are provided with limiting grooves 14, and limiting blocks 15 are arranged on both sides of the top of the mounting frame 9.
