Dry indoor low voltage transformer

General:

This type of voltage transformer and transformer are very similar, voltage transformers are used to transform the voltage on the line, in the 1kv circuit, the transformation voltage is mainly used to supply power to measuring instruments and relay protection devices, used to measure the voltage, power and electric energy of the line. Or used to protect the valuable equipment, motors and transformers in the line when the line fails, so the capacity of the voltage transformer is very small, generally only a few voltamps, tens of voltamps, and the maximum does not exceed one thousand voltamps, but the purpose of the transformer conversion voltage is to transport electrical energy, so the capacity is very large, generally based on kilovoltamps or megavolamps as a unit of calculation.

Key Feature

• The iron core system is made of cold-rolled silicon steel in C-shape, and the installation base and wiring pillar are fastened with tin-plated steel tape, and the primary and secondary coils are set on the middle column of two C-shaped iron cores.

• The primary winding terminal mark "a, x" is on the upper part, and the secondary winding terminal "a, x" is on the lower part.

• A mounting plate is provided at the bottom for user installation and a ground bolt is provided for grounding.
