Safe and stable isolated box closed type bus duct

Abstract

The invention provides a safe and stable partition box closed type bus duct which comprises a closed groove, a rear limiting plate and a front limiting plate are fixed to the upper side face of the closed groove, a left sliding block and a right sliding block are arranged between the rear limiting plate and the front limiting plate, a first return spring is arranged between the left sliding block and the right sliding block, and a second return spring is arranged between the left sliding block and the right sliding block. A left supporting column is fixed to the top face of the left sliding block, a left bearing is fixed to the top end of the left supporting column, a right supporting column is fixed to the top face of the right sliding block, a right bearing is fixed to the top end of the right supporting column, and the inner circumference of the left bearing makes contact with the outer circumference of the middle of the left rotating shaft. The inner periphery of the right bearing makes contact with the outer periphery of the middle of the right rotating shaft. According to the technical scheme, the technical problems that in the prior art, the bus duct connection guiding capability is not achieved, fire high-temperature monitoring cannot be achieved, and the diaphragm distance cannot be flexibly adjusted are effectively solved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the field of closed bus duct equipment, in particular to a safe and stable compartment closed bus duct. Background technique [0002] The closed busway is referred to as the busway, and the closed busway and the busway refer to the same thing. The closed bus duct is a bus system composed of metal plates as protective shells, conductive bars, plug-in bars and related accessories. It can be made into a plug-in closed busbar with a plug-in junction box at intervals, or a feed-type closed busbar without a junction box in the middle. The place where the closed busbar is applied is a low-voltage, high-current power supply and distribution system, which is generally installed in an electrical shaft, and a single central busbar system is used to supply and distribute power to each floor. [0003] The invention of safe and stable box-enclosed busway has brought various conveniences to people's production and life. In modern production...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a safe and stable compartment-enclosed busway to solve the technical problems in the prior art that do not have the ability to guide the connection of the busway and cannot realize high-temperature monitoring of fires and flexible adjustment of partition distances.
