Product description
When the AC asynchronous motor starts at the rated voltage, the initial starting current is very large, often exceeding many times the rated current (usually 5 to 7 times). In order to reduce the starting current and not affect the grid, the voltage is usually reduced. The method of starting the AC asynchronous motor is to use a reactor or a self-twisting transformer. The starting process of the AC motor is very short (generally several seconds to two minutes), and the reactor for step-down starting will be started after starting or Automatically cut off the transformer. The product is designed according to the starting characteristics of the high voltage asynchronous motor, matching the motor power 220 ~ 1400kw.

Features
1. The core of QKSG dry core starter reactor is made of high quality imported cold-rolled silicon steel sheet. The core column is divided into uniform small sections by multiple air gaps. The air gap is insulated by epoxy board and high temperature and high strength adhesive is used. In order to ensure that the air gap does not change when the reactor is running.
2. The end face of the iron core is made of high-quality silicon steel sheet end face glue, which makes the silicon steel sheets firmly combined, which greatly reduces the noise during operation and has better corrosion resistance.
3, coil wrapped structure, the main insulation of the coil is made of glass fiber impregnated epoxy resin, hot baked and vacuum immersed in high temperature insulation paint under vacuum, the coil not only has good insulation performance, but also high mechanical strength, can withstand motor start High current impact and thermal shock without cracking.

Conditions of Use
1. The altitude does not exceed 1000 meters.
2. Operating environment temperature is -25℃ ~ +45℃.
3. Installed in the indoors without violent vibration, without any harmful gas or dust, no flammable and explosive materials.
4. When the starting time is 2 minutes (one or several times), it should be cooled for 6 hours before starting again.

Performance parameter
1. The temperature resistance level reaches f (155℃).
2. The loss of the dry core starter reactor is lower than that of the oil immersed reactor.
3. The noise of the dry iron core starting reactor is not greater than the national standard.
