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 32-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
