HTR Series of Heat-Converting Resistor

HTR series of heat-converting resistors are applicable to large or medium-sized high voltage rat-cage AC asynchronous electric motors or asynchronously started high voltage synchronous electric motors for the purpose of starting by reducing the resistor voltage. The resistor takes advantage of the negative temperature trait of the resistor to achieve small and invariable current and the stepping-up rotating speed characteristic of the soft staring when starting the electric machine. As an international initiator, its starting performance is superior to that of the starting reactors and starting by self-reducing voltage.
The starters can be applied to the voltage-reducing starting of the 3, 6, 10kv large capacity electric machines with power range extending to 48, 000kw. The resistors can be produced to apply to electric machines with larger capacity to the needs of the users.

Main characteristics

Invariable current for soft starting: the starting current is 2.0â??â??3.5 times of the rated current of the electric machines.
It reduces heating of the electric machine, thus effectively prolonging its service life.
To ensure first-time success.
The staring process is stable, thus reducing impact on the mechanical equipment.
It has a very insignificant effect on the power grid and the power grid voltage decreases when starting.
