QKSC Series Resin Insulation Dry-Type Core Shunt Reactor

Short Description:

QKSC iron core starting reactor is suitable for 50Hz AC power system with rated working voltage of 6~35kV to limit the start-up current of motor. When AC asynchronous motor starts at rated voltage, the initial starting current will be very large, often many times exceeding of rated current. To reduce the starting current and influence on power grid, AC asynchronous motor or self-coupling transformer is usually started by voltage reduction method. The starting process of AC motor is very short. After starting, reactor or self-coupling transformer for step-down starting is removed. This product is designed according to the starting characteristics of high-voltage asynchronous motor and matches the motor power of 220 ~ 1400 (kW).

Conditions of use

1.ASL not exceeding 1000m;

2.Operating environment temperature being -25 ~ +45(℃);

3.Installed indoor places without violate vibration, harmful gases or dust, flammable and explosive articles;

4.When the start-up time reaches 2min, it shall be cooled for 6 hours before the second start-up.

Product structure

The iron core of QKSC type dry core starting reactor is made of high-quality imported cold rolled silicon steel sheets, of which the core leg is divided into small sections uniformly by a plurality of air gaps; the air gaps are isolated by epoxy plates, and high-temperature and high-strength adhesives are adopted to ensure that the air gaps do not change during the operation of the reactor;

The end face of the iron core is made of high-quality silicon steel sheet end face glue, so that the silicon steel sheets are firmly combined together, significantly reducing the noise in operation, and endowing better corrosion resistance; the coil adopts lapped structure in which the main insulation of the coil is made of glass fiber impregnated with epoxy resin, and is soaked with high-temperature resistant insulating paint under vacuum after hot drying and curing.

The coil has good insulation performance and high mechanical strength. It can withstand large current impact, cold and hot impact when the motor is started without cracking.
