CGR-HA MV/ HV soft starter shall be used with an inlet cabinet with a vacuum circuit breaker. As for the starting cabinet embedded HV motor protection system and protection system with no quick-break, users can choose according to their own situation.Technical
parametersThree-phase power supply: AC3KV, 6KV, 10KV, 15KV (-15%
+10%) Control power supply: AC/DC220V (-15% + 10%) Frequency: 50Hz,
60Hz ± 2% Applicable motor: Squirrel-cage asynchronous motor and
synchronous motor Starting frequency: Started frequently,
recommended frequency less than 10 times per hour. Protection
rating: IP4X Cooling mode: air cooled Installation position: Indoor
Service environment: derated if used in places 1500 meters above
sea level Ambient temperature: -25~ + 45° C Relative humidity:
Below 95% (20 ° C ± 5 ° C), without condensation Free of flammable,
explosive, corrosive gas, conductive dust, properly ventilated,
with vibration less than
0.6GWorking principal:CPU controls the SCR to conduct phase angle trigger control, lowering the voltage on motor, then controls the voltage on motor and increases the motor torque of the smooth current until motor runs in full speed. The above way of starting can lower the inrush current of motor, reducing the impact on power grid and motor itself. Meanwhile, it also reduces the mechanical impacts on motor loading device, prolonging device service life and reducing motor breakdown.

Diagram:Note: Cabinets shall be combined for use.Protection level
of thermal overload of motor The thermal overload protection of
electric motor is reverse time limit overload protection. It is
used to protect the motor by estimating the internal heat generated
by the motor in the process of starting or running with a
scientific calculation method. The mathematical model is
established referring to IEC60947-4-2 standard, JB/T 10613-2006
standard and the performance characteristics of AC asynchronous
motor in China. The overload protection curve of the starting power
motor is drawn in the coordinate system according to this
mathematical model, which is divided into 20 protection levels, as
shown in the figure below. Level 1~8 is used in the thermal
overload protection of motor operation and the factory default
value is 3; Level 9~16 is used in the thermal overload protection
of motor start and the factory default value is 0 (close
protection; no matter what kind of start mode, there is already
protection on startup time); Level 17~20 is standby. When the
thermal overload of motor does not reach the protection threshold
at the start and operation process, and the working current
recovers to the rated current, the heat integral constant can be
restored to its initial state within 3 minutes. If the thermal
overload of the motor exceeds the protection threshold, the soft
start enters the protection state. Typical wiring diagram and
