Air-type bus duct matching jack box

Abstract

The invention belongs to the technical field of power transmission and distribution, and discloses an air-type bus duct matching jack box. The air-type bus duct matching jack box comprises a box bodyand an isolating switch, and is characterized in that the isolating switch comprises a handle, a rotating shaft, an insulating shell and a joint terminal; the rotating shaft is installed inside the box body, the insulating shell wraps one end of the joint terminal and is installed on the rotating shaft, the handle is arranged outside the box body and is fixedly connected with the rotating shaft, the handle is rotated to drive the rotating shaft to rotate, and the other end, which is not wrapped, of the joint terminal can be collected into or rotated out of the box body. According to the invention, a circuit switch does not need to be specially arranged on the air-type bus duct matching jack box, the cost is saved, the fault risk points are reduced, the maintenance time is saved, and the maintenance and recovery time of a fault branch is accelerated on the basis of not influencing the power supply of other branches.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission and distribution, and in particular relates to an air-type bus duct matching socket box. Background technique [0002] Corresponding power transmission and distribution systems are indispensable for electrical equipment and power systems in high-rise buildings, factories, etc. Traditional power transmission and distribution systems use wire and cable wiring. With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing rapidly, especially the emergence of many high-rise buildings and large data center warehouses. Traditional cables used as power transmission and distribution wires are no longer suitable for large current transmission systems. To meet the requirements, the parallel use of multiple cables brings a lot of inconvenience to the on-site installation and construction connections. [0003] As a new type of ...

AI Technical Summary

Problems solved by technology

[0005] In the busway power transmission and distribution system, the air-type busway supporting connector box is an important part of it. The existing air-type busway supporting connector box is in contact with the conductor in the busway during installation. The on-off control of the box branch requires a special circuit switch on the plug-in box, which increases the cost of the plug-in box, and there is a probability of failure as an electrical component, which increases the risk of circuit failure

In addition, if the circuit switch fails, the power supply needs to be cut off when it is to be replaced and repaired, so there are only two options: one is to cut off the power from the source of the power supply of the bus duct, which will make the electrical equipment connected to the entire bus duct must be stopped for use, which is not allowed in scenarios such as data centers; the second is to separate the plug-in box that needs to be repaired from the busway, and install it after the repair is completed, which increases the time and cost of repair work. Takes time, cannot quickly restore power to the breakout box branch
