Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct joint protection device. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. If the joint position of the bus duct lacks protection, it is easy to cause low joint stability.

[0003] A bus duct joint protection device is disclosed in the utility model with application number 202221955399.5. When in use, the operator inserts the bus duct joint into the through groove on one side of the protective shell, and snaps the buckle at the protective shell into the slot, and then adjusts the knob to thread the bolt rod to one side of the protective shell, thereby realizing the installation of the bus duct joint protection device. The device has a simple structure, good fixation, and is relatively convenient to install and disassemble, which reduces the time for installing the bus duct and increases the efficiency of the installation work, thus solving the problems that the existing bus duct joint protection device has a relatively complex structure, the protection device is not convenient to install and disassemble, and the installation and disassembly project is relatively complicated. The problem of complicated installation, increased time for installing the bus duct, and reduced efficiency of the installation work is solved. When in use, the bus duct joint is clamped between the insulating spacers, and the insulating spacer clamps the bus duct joint into the groove opened by the insulating spacer. The device provides an insulating device to separate the bus duct joints from each other, effectively protecting the line after the bus duct joint is connected to the power, and the operator will not get an electric shock when installing and removing the protective shell, which solves the problem that the existing bus duct joint protection device does not provide an insulating device to separate the bus duct joints from each other. If there are debris overlapping the bus duct joint when power is on, there is a great chance of causing a short circuit in the line;

[0004] However, the above-mentioned bus duct joint protection device can only be connected in a straight line when encountering the joint of the bus duct body. When the joint is connected at a certain angle, a protective shell with a corresponding angle needs to be customized for installation and protection, which makes the production cost and difficulty of the protective shell high. The above-mentioned bus duct joint protection device connects the protective shell to the bus duct body through threaded holes and bolt rods, so that a gap is still left between the bus duct body and the protective shell. The lack of a sealing structure at the gap may cause the sealing protection at the bus duct joint to be reduced. Therefore, the utility model proposes a bus duct joint protection device to solve the problems existing in the prior art. Utility Model Content
