Zhejiang Dahu Electric Co., LTD is a professional manufacturer of high and low voltage transformers.
Technical parameters and application information about indoor casting through high voltage zero sequence current transformer LXK-80, 100, 120, 240 series are as follows:
LXK-φ80(100, 120) series zero sequence current transformer:
Suitable for rated frequency of 50Hz or 60Hz power system for zero sequence relay protection. This product is a cable through the center of the structure, so only the insulation of the secondary coil is considered. The secondary coil has a frequency withstand voltage of 3kV to ground.
Technical parameters:
Suitable for indoor, rated frequency 50Hz or 60Hz, rated voltage 35kV and below, small grounding current system for three-phase cable grounding protection, can also be used with relay protection.
When installing, the transformer can be divided into two halves, then merged into one, and clamped tightly with a hoop. It can be installed without power supply.
The product only opens and closes the insulation of the secondary winding, and the secondary winding withstand voltage to ground is 3kV for one minute.
LXK-Φ(80,120,140,160,200,240) type zero sequence current transformer:
Suitable for indoor, rated frequency 50Hz or 60Hz, rated voltage 35kV and below, small grounding current system for three-phase cable grounding protection.
Conventional models of this series are: LXK-φ80, LXK-φ100, LXK-φ120, LXK-φ150, LXK-φ180.
Installation and use:
This type is divided into two halves, cast into semicircle with resin, and then connected with clamping hoop. When installing, the transformer can be divided into two halves and then merged into one, making installation extremely convenient.
LXK-120 zero sequence current transformer:
Applicable to 10KV and the following current 50HZ line to do the power system and high-voltage three-phase alternator, motor zero sequence overcurrent protection, only for indoor. The outer diameter of the transmission cable is not greater than 120MM.
The above information provides detailed technical parameters and application scenarios of LXK series zero sequence current transformer for your reference.
