Outdoor IP65 waterproof Split Core Current Transformer for power
meter
Introduction
Overview The current transformer, the product complies with IEC
60044-1 IEC61869-2 Current Transformer"; for outdoor use rated
voltage of 10kV and below. For circuit control, protection and
other purposes.
II. Structure Introduction The current transformer with high
strength PVC shell, all cast bus structure. Transformer directly
stuck in the cable Three rubber rings to resist the cable and cable
with one. Transformer core using high-quality silicon steel roll,
the second wire wound evenly on the core. Transformer open
structure can not cut off the cable installation.
Features
New magnetic material is taken to be the core of the current
transformer, which has high magnetic permeability, low saturation
magnetization and good stability. Therefore, the measuring accuracy
is higher and the instrument security factor is lower. Since the
high quality silicon processed by advanced technology is taken to
be the core of the protection windings, which assured the accuracy
limit factor is higher.
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.
