Oil immersed inverted current transformer
Release time:2012-8-23
Introduce :
Product effect LVB series 35 kv ~ 220 kv oil immersed inverted current transformer, mainly for electric power system for current, power measurement and relay protection. The product structure
(1) insulation performance is good: 80% power frequency withstand voltage under local discharge magnitude is not more than 5 PC;
(2) the dielectric loss factor is low, the operation process of the rebound not;
(3) system short circuit resistance ability is strong, can meet the 63 ka / 3 s;
(4) the head adopts argon arc welding, sealed performance is reliable,
(5) the whole aluminum parts design antirust performance is excellent;
(6) performance is reliable, can free maintenance.
