Description

Technical Field

[0001] The invention relates to the technical field of lightning arrester installation, in particular to a fixing device for installing a zinc oxide lightning arrester. Background Art

[0002] Zinc oxide lightning arrester is an overvoltage protection device mainly composed of zinc oxide varistor, usually encapsulated in a porcelain sleeve or composite jacket. This type of lightning arrester is widely used in power systems to limit overvoltage and protect equipment from voltage shocks due to its excellent nonlinear resistance characteristics.

[0003] Zinc oxide lightning arresters must be connected in parallel between the protected equipment (such as transformers, switches, busbars, etc.) and the earth. One end of the lightning arrester is connected to the high-voltage wire or equipment terminal to be protected through a high-voltage down conductor. This connection point is usually the bolt on the upper end of the lightning arrester body. The other end is connected to the grounding device (grounding grid, grounding electrode) through a grounding down conductor. Lightning arresters are often installed on the crossarm of the pole-mounted disconnector or the crossarm of the high-voltage lead during installation. They are installed by a single bolt and nut. Since insulating gloves need to be worn during operation and the nut is small, it is very inconvenient to operate.

The top of the adjustment component 10 is connected to the positioning component 11, and the positioning component 11 can be used The high-voltage terminal 15 for connecting the high-voltage wire is quickly connected. The top of the card cover 9 is located on the inside of the adjustment component 10 and is connected to a squeeze spring 12. The top of the squeeze spring 12 is connected to a top plate 13. The inside of the top plate 13 is connected to a power connection piece 14. The power connection piece 14 is in contact with the bolt at the top of the arrester body 1. The elasticity of the squeeze spring 12 moves upward along with the top plate 13, thereby driving the power connection piece 14 to be in a state of fitting the high-voltage terminal 15. The elasticity of the squeeze spring 12 can press the high-voltage terminal 15 tightly against the inside of the positioning component 11 through the power connection piece 14.

Because it is a mature technology, it is not repeated in the description. A power indicator light 38 is connected to one side of the plug-in housing 71. The power indicator light 38 is connected to the collection and conversion unit. 72 is electrically connected, wherein the PVDF piezoelectric film 73 is divided into multiple groups, each group has multiple PVDF piezoelectric films 73, and each group of PVDF piezoelectric films 73 is electrically connected to two primary TVS tubes 722 and a Schottky diode 724. The primary TVS tube 722 absorbs high-voltage pulses, and the electric energy after passing through the Schottky diode 724 is then passed through the secondary TVS tube 723, which has the effect of preventing residual surges. The DC-DC boost module 726 boosts the electric energy after passing through the Schottky diode 724, and then charges the backup battery 727. At the same time, the supercapacitor 728 also has the effect of energy storage. The comparator 725 has the effect of keeping the output constant, thereby converting and collecting the electric energy generated by the PVDF piezoelectric film 73.

[0026] The implementation principle of the present application is as follows: when the invention is in use, the power connection component 3 is installed on the top of the lightning arrester body 1 through the connecting nut 17, and the insulating seat connection component 4 is installed on the bottom of the lightning arrester body 1. Then the worker moves to the crossarm to be installed with the help of climbing tools, inserts the positioning pin 54 from the top into the mounting hole on the crossarm, and then docks the extrusion component 6 with the crossarm component 5 from the bottom of the crossarm. Then, the connection component is driven by turning on the switch 78, so that the extrusion component 6 gradually moves toward the inside of the crossarm component 5 until the crossarm is clamped, thereby ensuring that the crossarm component 5 and the extrusion component 6 are connected to the crossarm. The connection stability is ensured, and then the quick connector 44 is docked to the positioning frame 28, and the quick connector 44 is limited and clamped by the limiting unit 55 to complete the installation of the lightning arrester body 1, and then the high-voltage terminal 15 on the equipment to be protected or the high-voltage wire is directly clamped into the positioning component 11, wherein the adjustment component 10 can be adjusted according to the angle of the high-voltage terminal 15 to ensure the connection effect. After the installation is completed, the drive component 7 is removed to install the next set of cross-arm components 5 and extrusion components 6, wherein the drive component 7 can store electricity and energy by rotation, and no additional energy consumption is required.
