Description

SVR-3 type Three phase Automatic Step voltage regulator

General

The SVR-3 type feeder automatic step voltage regulator is actually a three phase oil immersed auto-transformer with SVR controller and gathering sampling of voltage ¤t signal, on load tap charger controlling device to achieve gird more efficient from adjust the load character by increase and decrease the voltage.

So This SVR is eqv. To a transformer equipped with on load tap charger with SVR controller sampling voltage and current data and on load tap charger steps from current transformer and voltage transformer and limit switches.

2. Operating environment

(1) Below an altitude of 2000m

(2) Ambient temperature: Max. temperature is +40℃ and the min. temperature is -25℃

(3) Outdoor wind speed shall not exceed 35m/s

(4) Pollution grade: Class II

(5) Earthquake horizontal acceleration is not greater than 3m/s2,, the vertical

acceleration is not greater than 1.5m/ s2, and the safety factor is more than 1.67.
