1 Scope

This standard specifies the arresters, voltage surge protector and special terms used functional components, mainly for the development of standards, preparation of technical Art documents, translated professional manuals, textbooks, books and the like.

2 general terms

2.1 Used to protect electrical equipment from high transient over-voltage hazards and limit the freewheeling time often limit wheeling An electric appliance amplitude. This term It contains installation run the appliance for any external gap necessary for normal function, regardless of whether a component as a whole. Note 1. The arresters are usually connected between grid wires and the ground, but sometimes the connection between electrical wires or winding side. Note 2. The lightning is sometimes also referred to as over-voltage protection, over-voltage limiter (surgedivider). 2.2 SPD For limiting transient over-voltage and surge current electrical discharge, which contains at least one non-linear element. Note. Surge protectors also known as surge protectors. 2.3 By the non-linear metal oxide varistor series and (or) connected in parallel or in series and in parallel without discharge gap arrester. Note. No MOA also sometimes referred to as metal oxide surge arresters (metal-oxidesurgearrester or MOA), gapless surge arresters. 2.4 A metal oxide varistor and a discharge gap in series and/or parallel connection of surge arresters. 2.5 Having one or more discharge gap and one or more non-linear resistors in series or parallel arrester. Note. There is a gap-type surge arresters are sometimes also referred to as gap arrester. 2.6 Silicon carbide non-linear resistors in series with the discharge gap arrester. Silicon carbide Varistor discharge gap with non-magnetic blow arrester series composed of ordinary valve arrester. Silicon carbide non-linear resistors in series with the discharge gap magnetic blow arrester composed of magnetic blow valve type arrester. 2.7 An arrester insulator flashover generally applicable to dangerous power lines in order to reduce the impact when lightning transients. Note. not usually used to protect the insulator against other transient shocks, such as the impact of the operation. If necessary, it can also be used to protect the outside of the line insulator any He Appliances. ......
