Description

Method for manufacturing composite jacket gapless drop-out lightning arrester

Technical Field

The invention relates to the technical field of lightning arresters, in particular to a manufacturing method of a composite outer sleeve gapless drop-out lightning arrester.

Background

The drop-out (throw-in, detachable) arrester is obtained by modifying the distribution type zinc oxide arrester and then skillfully installing the modified arrester on the drop-out mechanism of the drop-out fuse, so that the arrester can be conveniently detected, maintained and replaced by means of the insulated brake operating lever under the condition of no power failure, thereby not only ensuring the smoothness of the circuit, but also greatly reducing the working strength and time of the power maintenance personnel, and being particularly suitable for places which are not suitable for power failure, such as communication, airports, stations, hospitals, luxury commercial areas and the like. The other properties of the product are the same as those of a distribution type lightning arrester.

The drop-out arrester is additionally provided with the disconnector, when the arrester abnormally breaks down, the disconnector is actuated by using power frequency short-circuit current, the grounding end of the disconnector is automatically disconnected, the arrester element is turned over, the operation is quitted, the accident is prevented from being further expanded, and a person easy to maintain can timely find the arrester element for maintenance and replacement. The principle of falling is similar to that of a fuse, and the fuse wire is blown to cause the fusion tube to fall. The international most advanced thermal explosion type disconnector adopted by the company has the advantages of high action speed, wide action current range and capability of enduring specified current impact and action load.

The arc striking angle piercing wire clamp mode adopted in the field of distribution network line lightning protection at present can effectively protect line wires and line insulators. However, in this method, arc is naturally extinguished at the zero crossing point of the arc current, the arc extinguishing capability is poor, the arc extinguishing time is long, and re-ignition is possible, so that the trip rate of the line cannot be reduced, and the automatic reclosing device needs to be matched with the automatic reclosing device. The traditional zinc oxide arrester and series gap arrester overvoltage protector mode can effectively protect an insulator from being damaged by electric arcs, reduces the line lightning stroke trip-out rate, but has the defects of high-voltage electricity aging of a zinc oxide resistor disc, sealing failure and damping of the resistor disc, complex series gap manufacturing process and the like, and the device is difficult to install due to heavy weight and large volume, has high operation and maintenance cost, and limits the wide popularization and application of the device in a distribution network.
