PRODUCT OVERVIEW

LDZKW-2 series outdoor split-core current transformers are suitable for current measurement, power acquisition, signal sampling and microcomputer protection of complete sets of electrical equipment in 0.66kV, 10kV and below AC power systems. The current transformer has the characteristics of small size, light weight, can be opened, and easy to install. It is widely used in the auxiliary engineering of compact fully insulated ring switch cabinet and transformer on the column. It is very suitable to form sampling unit with REMOTE distribution and transformation terminal equipment such as RTU and FTU to provide data support for the intelligent fusion terminal system of the whole station. When installing, it is directly stuck on the connected incoming and outgoing cables, which is simple and quick.

The series of current transformers use high quality imported silicon steel sheet with high permeability as magnetic conductivity material, which has the characteristics of divisible iron core and small magnetic circuit loss. The half-ring type iron core and secondary winding are vacuum poured into the flame retardant plastic shell with high quality epoxy resin, which is moisture-proof and stable in performance without maintenance.During installation, clamp the two semi-circles on the split-phase cable, and use the clamps to hold it tightly with the cable, which is harmonious and beautiful. It is applied to outdoor overhead lines, and is equipped with a customized silicone protective cover, which has the functions of anti-ultraviolet, anti-aging, and anti-moisture. Make sure that the transformer body does not cause water entry along the cutting surface of the iron core and cracking of the transformer surface due to the influence of the outdoor environment.

Product Features

Split-core structure, easy to install on site and easy to operate. Quick and easy installation or removal without disconnecting the primary cable under test;

Instrument security factor ≤ FS10; iron core magnetic circuit loss is small, to ensure the accuracy of the current transformer at 1%In;

For measurement, the accuracy grade is 0.5S;

Wide applicability, the sensor signal can be used for live detection, and can also be used as a signal source for online monitoring;

Adopt "304" stainless steel clamp and lock are fastened by positioning groove to ensure reliable docking of the end face of the iron core incision after locking, and excellent excitation performance.

Scope of Application
It is used for supporting the transformer on the pillar of the intelligent fusion terminal in the Taiwan area. It is used for the measurement of outdoor low-voltage electrical lines and the measurement of protection circuits. Compact fully insulated ring network switchgear; combined substation and cable distribution box.
