Embodiment 1

[0022] Wiring systems that are used in overhead line systems and have free movement functions, such as figure 1 As shown, it includes a lightning overvoltage protector, an insulator 17, a bracket device and a beam 16, the lightning overvoltage protector is fixed on the bracket device through a first bolt 11, and the insulator 17 is fixed through a bolt set 15 and a bracket The device is fixed on the crossbeam 16; the support device includes a secondary support 10 and a main support 12, the main support 12 is L-shaped, and a long hole 14 is provided on its long side, and its short side is fixed on the On the beam 16 ; the sub-support 10 is L-shaped, its long side is fixed to the lightning overvoltage protector through the first bolt 11 , and its short side is fixed to the elongated hole 14 through the second bolt 13 .

[0023] When in use, the lightning protection overvoltage protector, support device, insulator 17 and beam 16 are assembled and the beam 16 is connected to the t...

Embodiment 2

[0025] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 As shown, the lightning overvoltage protector includes an upper gasket 1, a lower gasket 2, a nut 3, a screw 4, a joint 5, and a current limiting element 9, and the joint 5 is arranged on the top and bottom of the current limiting element 9, The joint 5 at the bottom of the current limiting element 9 is fixed on the long side of the sub-support 10 by the first bolt 11; at the top of the current limiting element 9, the lower gasket 2 is placed on the top surface of the joint 5, and the upper gasket 1 It is arc-shaped, and the inner arc of the upper gasket 1 is opposite to the top surface of the lower gasket 2 , and the upper gasket 1 and the lower gasket 2 are fixed on the joint 5 through the nut 3 and the screw rod 4 .

[0026] In use, the wire 13 passes between the upper gasket 1 and the lower gasket 2 and is fixed by it. Since the upper gasket 1 is arc-shaped and the clamp spa...

Embodiment 3

[0028] This embodiment is further optimized on the basis of the above embodiments, the current limiting element 9 is a zinc oxide current limiting element, the joint 5 is made of a conductive metal material, and the upper gasket 1 and the lower gasket 2 are made of a conductive metal Material. Zinc oxide current-limiting element with non-linear resistance characteristics is used. During the discharge process, a so-called "residual voltage" will be reserved on the zinc oxide current-limiting element (non-linear resistance). After the lightning voltage, the system works Under high frequency voltage, it can extinguish power frequency freewheeling by itself, thereby keeping the system from losing voltage, avoiding the occurrence of system voltage loss and relay protection action tripping, thereby improving the quality of power supply to ensure normal power supply, increasing economic benefits, and improving power supply reliability .

Abstract

The invention discloses a wiring system with a free movement function applied to an elevated line system. The wiring system comprises a lightning protection overvoltage protector, an insulator, a bracket device and a cross beam, wherein the lightning protection overvoltage protector is fixedly arranged on the bracket device by virtue of a first bolt part; the insulator and the bracket device are fixedly arranged on the cross beam by virtue of a bolt unit; the bracket device comprises a secondary bracket and a primary bracket; the primary bracket is L-shaped, a strip-shaped hole is formed in the long side of the primary bracket, and the short side of the primary bracket is fixedly arranged on the cross beam by virtue of the bolt unit; and the secondary bracket is L-shaped, the long side of the secondary bracket is fixed with the lightning protection overvoltage protector by virtue of the first bolt part, and the short side of the secondary bracket is fixed on the strip-shaped hole by virtue of a second bolt part. The problem that time is consumed during the conventional installation and adjustment is solved, a fixing bracket is replaced by utilizing a mode of arranging the primary and secondary brackets in a split mode, and the adjustment is very conveniently performed during installation, so that the installation time is saved, and the aim of saving the mounting and using cost is achieved.

Description

technical field [0001] The invention relates to the technical field of electric power transmission, in particular, it is a wiring system applied to an overhead wire system and having the function of free movement. Background technique [0002] As an important part of the power system, cables play a pivotal role in the process of power transmission and distribution as the carrier of electric energy. Cables can be simply divided into low-voltage cables, high-voltage cables, and ultra-high-voltage cables according to their load conditions. According to whether the outer layer has insulation protection, it can be divided into bare wires and insulated wires. [0003] In the transmission and distribution lines of the power system, in order to achieve the effect of maximizing the transmission efficiency, high-voltage or even ultra-high-voltage power transmission is used for power transmission and distribution operations during long-distance power transmission. In the wilderness, du...
