MCC, MOTOR PROTECTION
RELAY
UNT-MMI
intelligent MCC (Motor Control Center) protection management device
is the new-generation digital-type intelligent MCC control
protection management device with strong interference resistance
developed by Baoding UNT Electric Co., Ltd. after studying similar
products in foreign countries and summarizing the typical design
experience of a lot of MCC electric systems in China, which is
based on the design characteristics of MCC circuit and for adapting
to the intelligent trend of secondary equipment in electric
system.
This product
is mainly used in low-voltage motor control circuit, so as to
achieve various protection, monitoring and control functions for
motor, and achieve the remote monitoring on motor circuit via field
bus.
Features of Device
With the
**-bit industrial microprocessor adopted, the speed is high and the
precision is also high.
The true RMS
algorithm is adopted for AC sampling, so as to fully reflect the
impact imposed by harmonic wave current.
The
self-adapted frequency-changing sampling technology is adopted,
which is suitable for frequency converter
circuit.
Several
flexible control modes are available, and control authorities are
interlocked.
The device
adopts the small-sized design, and the installation mode is
flexible.
Metal casing
design is adopted, so that external electromagnetic interference is
effectively shielded.
The LCD based
on Chinese characters and rich menu is adopted, and the interface
is user-friendly.
The switch
quantity circuit adopts the design of high interference
resistance, so as to ensure long transmission distance and high
reliability.
The internal
control contacts are equipped with protection circuit, and the
contacts can be effectively protected without additional surge
absorber.
Protection
Over-current
protection, Motor shaft lock protection, Current unbalance
protection, Earth fault, Over-voltage protection, under-voltage
protection
Phase sequence
protection, phase loss protection, over points off protection,
under-run protection, long start-up time protection, tE time
protection
