100 / 5A Split Core Current Transformer Dry Type
Introduction
The most common usage of current transformers is to operate
instruments or metering from high voltage or high current circuits,
safely isolating secondary control circuitry from the high voltages
or currents. The primary winding of the transformer is connected to
the high voltage or high current circuit, and the meter or relay is
connected to the secondary circuit. Installation With electricity,
suite for power monitor, energy loss etc.
Split core current transformers may also be used as an isolation
instrument transformer so that secondary quantities may be used in
phase shifting without affecting other primary connected devices.
Applications
LZCK322-10 split core current transformer is suitable forcurrent
measurement and microcomputer protection of electrical equipment in
10KV and 35KV AC power system.It is widely used in compact fully
insulated ring network switchgears such as ABB-Safe Ring/Safe
Plus...and cable distribution boxes.The transformer can be directly
installed at the inlet andoutlet cables.The slice is imported
silicon material. Thesemicircular ring core and secondary windings
arevacuum poured by insulated resin.
Features
The semicircular 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
and dispensing with maintenance.Small size, light weight, small
footprint, fixed in the ring network switchgear cable.The cable can
cross the current transformer through its internal poles quickly
and uniformly.
The Cast Resin Straight-Through Current Transformer can be divided
several kinds according to the various current ratio, accuracy and
rated loads. The specific parameters are showed in the
corresponding to each model parameter tables.
