Electrical cross arm for electric power supply system

Abstract

The invention relates to an electrical cross arm for an electric power supply system. The electrical cross arm for the electric power supply system comprises a connection sleeve frame. Angle iron brackets of a U-shaped structure are symmetrically arranged on the left side and the right side of the connection sleeve frame. The front side and the back side of each angle iron bracket are symmetrically provided with sliding grooves. Sliding blocks are arranged in the sliding grooves in a sliding fit manner. Insulators are arranged on the sliding blocks through rapid insertion mechanisms. Adjustingmechanisms are arranged between the siding blocks and the angle iron brackets. The electrical cross arm for the electric power supply system can solve the problems that during use of an existing electrical cross arm, it is difficult to replace a damaged insulator on the electrical cross arm, when the insulator is replaced, a dedicated detachment tool is needed, and operation is complicated; the existing electrical cross arm can only support an electric wire, cannot adjust changes, caused by thermal expansion and cold contraction, of the electric wire due to weather temperature change and cannot guarantee that the electric wire is always in the tightened state.

Description

technical field [0001] The invention relates to the technical field of electric cross-arm, in particular to an electric cross-arm for an electric power supply system. Background technique [0002] The power cross arm is an angle iron fixed horizontally on the top of the utility pole, with a porcelain bottle on it, which is used to support the overhead wires. It is mainly used to support the wires in the power supply system to prevent the wires from drooping downwards. [0003] However, the existing power cross-arm has the following problems in use, a. It is troublesome to replace the fixed porcelain bottle on the power cross-arm after it is damaged. When replacing, a special disassembly tool is required, and the operation is complicated; b can only support the electric wires. However, the thermal expansion and contraction of the wires caused by changes in weather and temperature cannot be adjusted, and it is impossible to ensure that the wires can always be in a tight state....

Problems solved by technology

[0003] However, the existing power cross-arm has the following problems in use, a. It is troublesome to replace the fixed porcelain bottle on the power cross-arm after it is damaged. When replacing, a special disassembly tool is required, and the operation is complicated; b can only support the electric wires. However, the changes in thermal expansion and contraction of wires caused by changes in weather and temperature cannot be adjusted, and it is impossible to ensure that the wires can always be in a tight state.

[0004] Regarding some problems existing in the use of power cross-arms, related industries have made research and proposed specific technical solutions, such as the Chinese invention patent No. 2018116002306, which is a kind of power installation cross-arm, which is fixed in the hollow The driving assembly between the beam and the connecting rod can drive the connecting rod to move forward from the hollow fixed beam and lock in this position to extend the distance from the fixing hole to the other end of the cable, and finally realize the tension of the connecting rod to the front side The effect of the cable, avoiding the interruption of the power supply caused by the cable becoming loose, however, the problems mentioned above about the use of the power crossarm are not involved
