LXZ Type Zero Sequence Current Transformer


LXZK Type Zero Sequence Current Transformer

General description:

LXZK type zero sequence current transformer is summarized Hyliton company of zero sequence current transformer operation is based on the experience of development with independent intellectual property rights of the new products,(the patent number ZL 2006 0119224.5), are widely used in communication in power system, power distribution lines and ac generators, motors electrical equipment such as zero sequence overcurrent protection and small current grounding route.

Since the high quality silicon steel sheet metal processed by advanced technology is taken to be the ring core of the transformer, the accuracy limit factor will be higher. The ring core and secondary windings are vacuum poured by high quality epoxide resin in the fire retardant plastic casing, which has the characteristic of moisture proof, stable performance, dispensing with maintenance, small volume and light weight.

LXZK open type current transformer consists of two semicircles, which can be installed with the cable quickly and uniformly.

LXZ Type Zero Sequence Current Transformer

General description:

LXZ zero sequence current transformer is suitable for use in 10kV power system of three-phase zero sequence current detection and single-phase grounding protection. When it is used in the line switches for single phase ground protection, there is Watch DOG characteristic. At preseng, it has been widely used inVSP5 type line switches.

Its accuracy is high since that high quality silicon steel sheet metal slug with very high magnetic permeability as transmit magnetism material are used. Furthermore, its core and secondary windings are vacuum poured by high quality epoxide resin which has the characteristic of moisture proof,good insulating property and dispensing with maintenance.

The current transformers can be divided several kinds according to the various current ratio, accuracy and rated loads. The specific parameters are showed in the corresponding parameter tables of every type.
