China manufacturer 14.4kv oil immerserd type single phase step voltage regulator

 China manufacturer 14.4kv oil immerserd type single phase step voltage regulator

Description

ZBSVR, feeder voltage regulator, is a single-phase autotransformer, with 32 file intelligent controller switch, and the  controller to cooperate to complete 32 files, ZBSVR single-phase step voltage regulators are tap-changing autotransformers. They regulate distribution line voltages from 10% raise (boost) to 10% lower (buck) in thirty-two steps of approximately 5/8% each. Voltage ratings are available from 10000volts to 35000 volts  for 60 Hz and 50 Hz systems.Internal potential winding taps and an external ratio correction transformer are provided on all ratings so that each regulator may be applied to more than one system voltage.

Advantages

High accuracy: within the range of set voltage regulation, 32 steps on load automatic voltage regulator;
Long life: unique design of on load taps, to avoid the regulator arc, can ensure the operating life of nearly a million times;
Maintenance-free: fully sealed design, high protection level, excellent weatherability, long maintenance-free;
Flexibility: installed flexibly in the lines or substations, it can withdraw operation if necessary or open and close its regulator function;
Functions: it can be used directly with the SCADA system and complete distribution automation;
Low loss: single-phase design minimizes the iron loss, reducing load loss;
Economy: cost-effectively adjust the line voltage, dramatically reducing line losses and increase equipment life span.
