description

feature

parameter

when the voltage of the power grid fluctuates, in order to provide high-quality stable voltage, it is necessary to adjust the voltage of the transformer; reliable uninterrupted power supply is becoming increasingly important to users, and the application of on load voltage regulating transformers is becoming more widespread; integrated design of on load voltage regulating transformer, compact structure, small footprint, and convenient installation; the on load tap changer adopts a dry vacuum box structure, consisting of an electric mechanism, a vacuum switch with transition resistance, and a tap changer selector; on load tap changer automatic controller, convenient for on-site or remote control, and can provide microcomputer interface according to user needs;
outstanding advantages: the resin mixing material adopts advanced mixing methods and vacuum film degassing techniques from abroad, ensuring uniform mixing and eliminating bubbles in the mixture. the product only has extremely low partial discharge capacity, which can be controlled below 5pc. the casting body has a dense solidification structure, which is flame retardant, explosion-proof, and does not pollute the environment. the iron core adopts high-performance cold rolled oriented silicon steel sheets, and is equipped with a fully automatic robot lamination machine. it has small shear burrs and low lamination coefficient, effectively reducing the no-load loss, no-load current, and noise of the transformer. the no-load loss is reduced by 5% to 10% compared to manual lamination.

on load voltage regulation: it can automatically detect voltage fluctuations in the power grid and adjust the gear position.
low noise: meeting the requirements of the low noise standard of the state grid south network;
low partial discharge: the product only has extremely low partial discharge capacity, which can be controlled below 5pc.
high mechanical strength: the epoxy casting body has a dense curing structure that can withstand sudden short circuit electrodynamic forces without damage.
