Abstract

The utility model provides a lightning arrester with an external serial discharge gap. According to the lightning arrester, the external discharge gap consisting of an upper discharge ring and a lower equalizing ring is connected in series with a guide drawing rod of a lightning arrester main body, and a silicone rubber insulating layer with an umbrella skirt is solidified on the surface of the guide drawing rod between the upper discharge ring and a connecting sleeve of the lower equalizing ring. By the technical scheme, the phenomena of surface ionization discharge and flashover disruptive discharge of the guide drawing rod are effectively prevented, the insulation creep distance of the external discharge gap is increased, and the stability of the discharge performance of the external serial discharge gap is improved.

Description

Outer series connection discharging gap lightning arrester
Technical field
The utility model relates to the external series gap lightning arrester that is connected in the power distribution circuit.
Background technology
Need install lightning protection equipment additional in the power distribution circuit---the outdoor type external series gap lightning arrester; It has on the leading-drawing rod of lightning arrester main body series connection be provided with outside the main-body structure of discharging gap; Outer discharging gap is made up of upward discharge ring and lower uniform pressure ring with discharge spacing; When its design theory surpassed design load when the voltage difference that between last discharge ring and lower uniform pressure ring, forms, the air insulation clearance that punctures both was implemented discharge.But in the actual motion; Because of being attached to the influence of the aspects such as dew, dust and leading-drawing rod material of leading-drawing rod; Electrical discharge arc can directly be walked from the leading-drawing rod surface, but not punctures air insulation clearance by specification requirement, does not reach the electric property requirement that the product lightning protection is designed at all; Cause properties of product changeable, unstable, be difficult to bear the security capabilities of the lightning-arrest discharge prevention of power distribution circuit.
Summary of the invention
The goal of the invention of the utility model is to provide a kind of outer series connection discharging gap lightning arrester with stable disruptive discharge performance.The outer series connection discharging gap lightning arrester technical scheme that the utility model provides; Its major technique content is: a kind of outer series connection discharging gap lightning arrester; Series connection is provided with the outer discharging gap that is made up of last discharge ring and lower uniform pressure ring on the leading-drawing rod of lightning arrester main body, is solidified with the silicone rubber insulation layer that has full skirt on the leading-drawing rod surface between last discharge ring and the lower uniform pressure ring adapter sleeve.
The outer series connection discharging gap lightning arrester technical scheme that the utility model provides; Discharging gap place between last discharge ring and lower uniform pressure ring is provided with silicone rubber insulation layer, and leading-drawing rod no longer is exposed in the atmospheric environment, avoids discharge of leading-drawing rod surface ionization and flashover breakdown discharge; Especially the umbrella skirt construction setting of silicone rubber insulation layer; Strengthened the insulation creep distance of outer discharging gap, the generation of having stopped inner non-grading ring electric discharge phenomena has improved the stability of outer series connection discharging gap discharge performance.
Description of drawings
Accompanying drawing 1 be this outer series connection discharging gap lightning arrester partly cut open the general assembly structure chart.
Embodiment
The disclosed outer series connection discharging gap lightning arrester of the utility model; It implements structure shown in accompanying drawing 1; Series connection is provided with the outer discharging gap that is made up of last discharge ring 4 and lower uniform pressure ring 3 on the leading-drawing rod 2 of lightning arrester main body 1; Lower uniform pressure ring 3 is to be fixedly mounted on the leading-drawing rod 2 through adapter sleeve 6; Leading-drawing rod 2 surfaces between last discharge ring 4 and the lower uniform pressure ring adapter sleeve 6 are gone up and are coated with the silicone rubber insulation layer that has a full skirt 5 through the vulcanizing mold press fit, and full skirt 5 diameters of silicone rubber insulation layer are preferably less than lower uniform pressure ring 3 internal orifices footpath diameter.
