Oil Immersed Current Transformer

Henan GNEE Electric Co., Ltd. is one of the most reliable manufacturers and suppliers of oil immersed current transformer in China. If you're going to buy customized oil immersed current transformer made in China, welcome to get quotation from our factory. Quality products and reasonable price are available.

The LCWD-35 oil-immersed current transformer is compact, small in size, and light in weight. The upper half contains the primary winding, while the lower half contains the secondary winding. The bushing is fixed on the base, with an oil conservator mounted on top. The primary winding is led out from both sides of the cabinet wall. The starting terminal, marked P1, is insulated from the cabinet wall by a small porcelain sleeve, while the end terminal, P2, is directly connected to the cabinet wall. The front of the oil conservator is equipped with oil gauges indicating different temperatures.

In the stages of power generation, substation, transmission, distribution, and consumption, the current can vary greatly, ranging from a few amperes to tens of thousands of amperes. To facilitate measurement, protection, and control, this current needs to be converted into a relatively uniform value. Additionally, since the voltage on the line is generally quite high, direct measurement would be very dangerous. The current transformer serves the purpose of current transformation and electrical isolation.

Through the introduction of advanced technology, an inverted oil-immersed current transformer was developed in China. This product is an oil-immersed, cable paper-insulated current transformer. The secondary coil is encased by a metal shield and placed at the top of the product, with a metal tube located inside the secondary coil. On the low-voltage side, the secondary coil and lead metal tube are not covered with cable paper or crepe paper insulation, and the primary line is typically a straight copper or aluminum tube.

The advantages of this product include its compact size, lightweight design, attractive appearance, and strong ability to withstand dynamic heat and maintain stable current. However, the disadvantage is that the insulation wrapping of the coil section and the lead tube section cannot be completed in one step. The insulation wrapping of the coil section must be done manually and then connected with the lead tubes, which need to be insulated and butt jointed. This process is time-consuming and labor-intensive, resulting in a longer processing cycle.
