Lightning arrester used for transformer substation

Abstract

The invention relates to the technical field of electric power, and discloses a lightning arrester used for a transformer substation. The device includes an installation base, the top of the installation base is fixedly provided with a hollow support column, and the top of the hollow support column is fixedly provided with a sealing bottom plate. When the lightning arrester used for the transformer substation is connected with a ground wire, the ground wire is clamped between a jig and an L-shaped jig, since the L-shaped jig is fixed, the ground wire can squeeze the movable jig, and a conductive needle thus can be inserted in a clamp groove on the bottom of a conductive rod; in this way, thunder and lightning can be introduced in a thunder-and-lightning introduction core through a main lightning receiving rod and a secondary lightning receiving rod, then thunder and lightning are transmitted to the conductive needle through the conductive rod, and thunder and lightning can be introduced underground through the ground wire. When the ground wire is taken down, a spring and a limiting block make the conductive needle separated from the inside of the clamp groove of the conductive rod,then the conductive function of the device can be broken, in this way, installation and dismantling of the ground wire are effectively facilitated, and the installation efficiency of the ground wireis improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a lightning protection device for a substation. Background technique [0002] Electricity is an energy powered by electric energy. It was invented in the 1870s. The invention and application of electric power set off the second industrialization climax and became one of the three scientific and technological revolutions in the world since the eighteenth century in human history. It has changed people's lives. The large-scale power system that appeared in the 20th century is one of the most important achievements in the history of human engineering science. It is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. , it converts the primary energy of nature into electricity through mechanical energy devices, and then supplies electricity to various users through power tra...
