product description

Whether testing or heating, it is necessary to increase the current from the power supply voltage, so that the secondary current can reach several thousand or more than ten thousand amperes. Different, it is a series of its own for industrial and mining enterprises to use. When using this series of products, it is generally necessary to install a voltage regulator before the power supply, so that the secondary test can be adjusted to the first level. Some products are equipped with primary taps, which only allow the voltage to be adjusted after cutting the power supply.

Product Usage

DDG type low voltage transformer series is suitable for continuous load test and current boosting of switches, current transformers or other electrical equipment with a rated efficiency of 50 Hz.

Structure

The primary coil of this series of products is generally cylindrical, and the secondary is generally a spiral coil formed by bending a bare foreign body. Generally, the primary coil has no voltage regulating tap. The voltage conversion of the secondary coil is achieved by series and parallel connection. Combinations are 1/1-12. Transformer iron cores are all core-type iron cores, which are stacked by electrical silicon steel sheets. The iron column adopts a multi-step circular section; As a clamp, the yoke screw is used to achieve the purpose of compressing the iron core.
