LB series of oil-immersed vertical current transformers are vertical and fully closed structure, mainly by the expander, a terminal, porcelain sets, primary winding, secondary winding, fuel tank and other parts, the lower part of the product with grounding plate for products Ground, with a drain valve for oil samples.
The maximum wind speed does not exceed 34 m / s; for the seismic intensity of not more than 8 (the maximum temperature of 25 ℃); the maximum wind speed of not more than 34 m / s; Of the region.
Product insulation performance: 80% of the partial discharge under the power frequency voltage is not greater than 5pC; dielectric loss factor is low, the process does not rebound; one can achieve multiple turns, easy to meet the current relatively small hours of precision requirements; Can be used to meet a number of test oil; low center of gravity, good seismic performance for earthquake; reliable structure, stable operation.
