Zinc oxide arrester and preparation method

Abstract

The invention discloses a zinc oxide arrester, which comprises the following components percentage by weight percentage: 3.5wt%-4.0wt% of bismuth oxide, 2.7%-3.6% of nano antimony oxide, 1.0wt%-1.8wt%of cobalt oxide, 0.6wt%-1.3wt% of silicon oxide, 0.6wt%-0.9wt% of manganese oxide, 0.8wt%-1.4wt% of chromium oxide, 0.06wt%-0.14wt% of nickel oxide, 0.8wt%-1.2wt% of yttrium oxide, 0.8wt%-1.2wt% of ytterbium oxide, and the balance zinc oxide. The zinc oxide arrester provided by the invention solves the technical problems of large equipment floor space, high production, transportation and installation cost, high raw material consumption, great threat to raw material resources and the like due to huge equipment exterior dimension and small wiring space for users in an outgoing chamber caused bylow potential gradient of zinc oxide arrester.

Description

technical field [0001] The invention belongs to the preparation technology of lightning arresters, in particular to a zinc oxide lightning arrester and a preparation method. Background technique [0002] At present, there are nearly 400 arrester manufacturers in my country. Over the years, the lightning arrester industry has undergone many changes in terms of enterprise scale and quantity, technological progress, material innovation, production equipment, quality control, etc. The overall technical level of the industry has improved and the stability of product quality has increased. Most enterprises generally have low technical level, unstable product quality, and some even do not have complete testing methods at all. The technical level has led to the main problems of power equipment in our country: the equipment is bulky in appearance, and the space for user wiring in the outlet room is small, so the equipment occupies a large area, the cost of production, transportation...
