Problems solved by technology

The preventive test period stipulated by the zinc oxide arrester is 3-5 years. When the spring maintenance is required, the arrester will be removed uniformly for test and inspection, and unqualified and family defect arresters will be found in time to be replaced. The current problem is that the initial installation uses a simple The method of adding cross-arms to bolts, due to the long age and wind and rain, the bolts are corroded, which makes it difficult to disassemble and assemble the arrester. During the disassembly process, the arrester is repeatedly twisted to cause the seal to damage the actual effect of the valve body.

Embodiment Construction

[0021] Such as Figure 1-Figure 4 The zinc oxide arrester installation base shown includes an elastic bow-shaped support 1 and a cross arm 5 to be installed. In this embodiment, the bow-shaped support 1 is used for installing the zinc oxide arrester 3 . Such as Figure 4 As shown, the angle between the tangent line 16 on the bow support 1 and the horizontal line in the initial state is 30°. The two ends of the bow support 1 are symmetrically provided with positioning handles 11 arranged horizontally, and the two positioning handles 11 are provided with fixing devices that cooperate with the cross arm 5 to be installed. In this embodiment, the fixing devices include two positioning handles 11. The two sides of the cross arm 5 to be installed are symmetrically provided with screw holes, and the wing bolts 4 screwed to the screw holes are installed in the bore holes. When the bow support 1 needs to be installed on the cross arm 5 to be installed, Locking and positioning can be ...

Abstract

The invention discloses a zinc oxide lightning arrester mounting base, which comprises an arcuate stent having elasticity, A plurality of mounting supports are mounted on the bracket, and a zinc oxidelightning arrester is mounted on the mounting supports. The structure enables the zinc oxide lightning arrester to be mounted on a cross arm to be mounted through an arc-shaped bracket, thereby facilitating the disassembly and installation of the zinc oxide lightning arrester, and avoiding the phenomenon of repeatedly twisting the lightning arrester during the disassembly and assembly process tocause the sealing damage to the valve body actual effect. But also can change and maintain the installation angle of zinc oxide lightning arrester, and has high safety.

Description

technical field [0001] The invention relates to a zinc oxide lightning arrester installation base. Background technique [0002] Zinc oxide arrester Zinc oxide arrester is a surge arrester with good protection performance. Utilizing the good nonlinear volt-ampere characteristics of zinc oxide, the current flowing through the arrester at normal operating voltage is extremely small (microampere or milliampere level); when the overvoltage acts, the resistance drops sharply, and the energy of the overvoltage is released. To achieve the effect of protection. The difference between this arrester and the traditional arrester is that it has no discharge gap, and uses the nonlinear characteristics of zinc oxide to play the role of leakage and breaking. The preventive test period stipulated by the zinc oxide arrester is 3-5 years. When the spring maintenance is required, the arrester will be removed uniformly for test and inspection, and unqualified and family defect arresters will ...
