A bypass construction system for agricultural distribution network lines

Abstract

The invention discloses a bypass setting-up system for rural power distribution network lines. The system includes a mobile cable distributing vehicle, a tension machine, a flexible cable, a cable distribution haulage component, a haulage rope, a winching device, a load switch vehicle and a cable distributing pulley. The mobile cable distributing vehicle comprises a caterpillar base plate, a cable rotating disk and a drive device of the cable rotating disk. The flexible cable on the cable rotating disk is a specially designed tension flexible cable. The front end and the rear end of the cable distribution haulage component are respectively connected to the haulage rope and the flexible cable. The haulage rope hauls the cable distribution haulage component to pass through the cable distributing pulley fixed on an electric pole to be fixed on a rotating disk of the winching device. A rotating disk of an electric disk is controlled to discharge the cable and simultaneously a rotating disk of the winching device is rotated to realize setting up of the flexible cable. The load switch vehicle comprises a caterpillar base plate and a load switch. The load switch can be erected or laid down. After the load switch and the flexible cable are joint together, the on-off of a bypass can be controlled. The mobile cable distributing vehicle and the load switch vehicle both realize automatic vehiclerying of the flexible cable and the load switch through the caterpillar base plates, thereby making set-up of the whole bypass safe and highly efficient.

Description

technical field [0001] The invention relates to an agricultural distribution network line, in particular to a bypass construction system for the agricultural distribution network line. Background technique [0002] With the rapid development of the rural economy and the increase of household appliances year by year, all walks of life have higher and higher requirements for the reliability of the power supply of the rural distribution network. Electricity demand, live work has also begun to gradually extend to the agricultural distribution network. [0003] With the rapid development of the rural economy and the increase of household appliances year by year, the uninterrupted operation of the distribution network has begun to be promoted from the urban distribution network to the rural distribution network. The "bypass operation method" is mainly used for live maintenance of distribution network lines. Its working principle is to quickly build a temporary bypass power supply...

Problems solved by technology

[0004] However, since the lines of the agricultural distribution network are mostly located in mountainous areas, hills and rice fields, the roads are narrow and the traffic is inconvenient, cable cars and insulated bucket trucks for bypass operations cannot enter the work site of the agricultural distribution network, so the conventional bypass operation method must be carried out in the agricultural distribution network. In the development, there are problems that the bypass cable is difficult to carry and the cable turntable is not easy to install and fix.

The load switch also has the problems of difficult handling and installation

[0005] In addition, the current conventional cable has only one shielding layer, which is braided with tinned copper wire + Kelvar fiber in half and half, and the metal wire and fiber will interact with each other during the braiding process. The hardness is greater than that of the fiber, so there is a defect that the metal wire is easy to split the fiber; on the other hand, the surface coverage of the composite braided copper wire is small, and its ability to prevent the interference of the external electromagnetic signal of the cable is relatively poor; the composite braided copper wire Mixed with fibers, it is difficult to separate, and the operation is cumbersome and time-consuming when connecting; the most important thing is that the number of fibers used in composite braiding is small, so the longitudinal tensile force of the cable is poor, and the ability to withstand tension is poor

[0006] Therefore, when using the existing bypass operation method for cable installation, the bypass operator needs to stand on the insulating platform installed on the tower to work, and then suspend the steel wire rope and bypass cable on the tower. The laying process is very complicated. Operators are not safe
