The invention discloses a protection framework for a lightning arrester. The protection framework for the lightning arrester solves the technical problem that an umbrella skirt of an existing lightning arrester is high in possibility of being damaged in a disassembled process. The protection framework for the lightning arrester comprises an upper framework, a lower framework and an insulating rod connected between the upper framework and the lower framework; the upper framework is provided with a clamping ring for clamping the upper end of the lightning arrester; a movable connecting rod is connected between the clamping ring and the upper framework; a ring support is fixedly connected with the lower framework; and the ring support is provided with a clamp for clamping the lower end of the lightning arrester. The embodiment of the protection framework for the lightning arrester is applied into the disassembled and mounted processes of the lightning arresters.
Description
【Technical field】 [0001] The invention relates to a protection frame of a lightning arrester, which belongs to the technical field of lightning arresters. 【Background technique】 [0002] In the prior art, since zinc oxide arresters have good protection performance, zinc oxide arresters are often used as arresters. Zinc oxide arresters are composed of zinc oxide resistors and composite silicone rubber sheds. In order to ensure the working performance of zinc oxide arresters, regular Disassemble for performance test. Because the composite silicone rubber material is easy to age, it is often damaged by external force during the disassembly process, which affects the working performance of the zinc oxide arrester and shortens the service life of the arrester. 【Content of invention】 [0003] The problem to be solved by the present invention is to provide a protective frame for the arrester, which can prevent the shed of the arrester from being damaged during disassembly, ensur...
