Protective telescopic lightning arrester for outdoor power distribution equipment

Abstract

The invention relates to the technical field of outdoor power distribution equipment lightning protection, and in particular to a protective telescopic lightning arrester for outdoor power distribution equipment. The lightning arrester comprises outdoor power distribution equipment, a supporting base, a telescopic cylinder and a lightning arrester body; the top of the outdoor power distribution equipment is fixedly provided with a contraction cylinder through a fixing base. The lightning arrester body is fixedly installed at the top end of the contraction cylinder. A stable support is fixedlymounted at the bottom end of the outdoor power distribution equipment; rubber pads are arranged on two sides of the outer wall of the contraction cylinder. A fixed angle steel is fixedly installed between the rubber pad and the fixing base; two ends of the fixed angle steel are fixedly connected with the fixing base and the rubber pad through fixing bolts correspondingly. A telescopic mechanism isarranged in the contraction cylinder, automatic telescopic control can be achieved through the arranged telescopic mechanism, the lightning arrester body can be contracted in the contraction cylinder, the lightning arrester can be protected through the arranged contraction cylinder, and the service life of the lightning arrester body is prolonged.

Description

technical field [0001] The invention relates to the field of outdoor power distribution lightning protection equipment, in particular to a protective retractable lightning arrester for outdoor power distribution equipment. Background technique [0002] Lightning arrester is a device that protects electrical equipment from lightning damage. It is used to protect various electrical equipment in the power system from damage caused by lightning overvoltage, operating overvoltage, and power frequency transient overvoltage. [0003] However, the stability of the existing outdoor power distribution equipment is not high during installation, and the lightning arresters installed on the power distribution equipment are generally exposed outside, and the safety performance cannot be guaranteed, which makes it easy to cause damage to the lightning arrester when the power distribution equipment is installed and transported. It does not have any protective function, and at the same time,...

Problems solved by technology

[0003] However, the stability of the existing outdoor power distribution equipment is not high during installation, and the lightning arresters installed on the power distribution equipment are generally exposed outside, and the safety performance cannot be guaranteed, which makes it easy to cause damage to the lightning arrester when the power distribution equipment is installed and transported. It does not have any protective function. At the same time, the force and vibration of the existing arrester during use will increase the loss speed of the arrester, reduce the service life of the arrester, and make it inconvenient to use
