Long-distance insulated power transmission bus

Abstract

The invention discloses a long-distance insulated power transmission bus which includes a protection box. A protection groove is formed in the top of the protection box, positioning plates are slidably connected to the inner walls of the two sides of the protection grooves, and the bottoms of the positioning plates are fixedly connected with extension springs; moving plates are fixedly connected to the bottoms of the extension springs, one sides of the moving plates are slidably connected to the side wall of the protection groove, buffer hydraulic rods are fixedly installed on the sides, closeto each other, of the two moving plates, and a same placing plate is fixedly connected to the sides, close to each other, of the two buffer hydraulic rods; and a placing groove is formed in the top of the placing plate, and cushion pads are fixedly connected to the inner walls of the two sides of the placing groove. The long-distance insulated power transmission bus is simple in structure, buffersprings, the extension springs and the buffer hydraulic rods are utilized to carry out buffering protection on vibration generated during the power transmission bus body transportation, the skin of apower transmission bus body is prevented from abrasion, and the integrity of the power transmission bus body is protected.

Problems solved by technology

In the power system, the power transmission bus connects the various current-carrying branch circuits in the power distribution device, and plays the role of collecting, distributing and transmitting electric energy. Therefore, the power transmission bus is used in large quantities in power distribution equipment. When transporting a large number of power transmission buses to various power distribution equipment, they are often directly put into transport vehicles without protective equipment and transported to the destination, but there will be bumps during the driving of the vehicle, and the resulting bumps will make the power transmission bus The friction between the skin and the compartment will cause damage to the skin of the transmission bus and affect its insulation performance. Therefore, we propose a long-distance insulated transmission bus to solve the above problems
