Wire positioning device of insulator

Abstract

The invention discloses a wire positioning device of an insulator. The wire is placed in the groove arranged on the upper surface of the insulator upper cap; the wire passes through circular cavitiesarranged at the two ends of the groove; a first half round clamp and a second half round clamp are clamped between the insulator upper cap and the insulator porcelain piece by locking the locking nutarranged on the locking device; and meanwhile, a first arc clamping section and a second arc clamping section at both ends clamp the wire harness in the circular cavity for positioning. When the wireharness is small, a first arc adjustment section and a second arc adjustment section are used for micro-adjustment, that is, the position of each arc adjustment section is adjusted by screwing the locking nut arranged at the end of each adjusting rod to clamp the wire harness for positioning. By means of the wire positioning device of the insulator, the fixing with binding mode is avoided, and thesecurity of wire positioning is improved.

Description

technical field [0001] The invention relates to an insulator wire positioning device. Background technique [0002] With the rapid development of my country's national economy and the rapid improvement of people's living standards, the demand for electricity is increasing, and higher requirements are put forward for the reliability, quality and safety of power supply. The normal operation of 10kV distribution lines is directly related to people's work, study and life, so it is very important to ensure the safe, stable and trouble-free operation of the 10kV overhead line distribution network system. The existing insulator comprises an insulating porcelain part, an upper cap and a lower cap installed at both ends of the insulating porcelain part, and the upper cap is provided with grooves for placing wires. The wire on the traditional 10 kV distribution line is fixed by binding the steel core aluminum wire (overhead insulated wire) to the porcelain insulator with an aluminum ...

AI Technical Summary

Problems solved by technology

The wire on the traditional 10 kV distribution line is fixed by binding the steel core aluminum wire (overhead insulated wire) to the porcelain insulator with an aluminum wire (sheath wire). This method has been used in China and has not changed until now. In practice, we found that it has the following defects: (1) Due to the natural monsoon, rain, and snow force between the wire and the bound wire and the insulator, there is a slight vibration between the wire and the bound wire and the insulator

Under the action of external force for a long time, the binding wire will gradually loosen, resulting in complete loosening of the binding wire, wear of the wire, wear of the porcelain insulator, and even the wire is simply worn off in the end, resulting in power failure and personal injury accidents caused by the wire falling

(2) Although there are requirements for binding methods in the binding operation using aluminum binding wires, because each person's method is different or the same person cannot be consistent every time, the quality of binding is greatly affected by human factors, and the level of construction technology is difficult. control

(3) After the construction is completed, it is difficult to control and find out the construction process due to the difficulty in acceptance at high altitudes.

(4) Due to the huge number of insulators on the 10 kV distribution line, regular maintenance is difficult
