AC induction motor rated voltage starter, the initial starting current, often many times more than the rated current (typically 5 to 7 times), in order to reduce the starting current, not grid impact, usually used to reduce the voltage way to start the AC induction motor, the step-down method is used reactor or autotransformer AC motor starting process is very short (typically a few seconds to two minutes), will start after the buck starting reactor or from the The coupling transformer resection. The the relay power design production start reactor QKSG startup characteristics of the high-voltage asynchronous motor design, matching motor power 220 12000kW. Second, start the reactor core dry type iron core of the structural characteristics 1.QKSG type using quality oriented silicon steel core columns by the number of air into uniform small pieces, air gap using the the epoxy board as isolated, and high temperature high strength adhesive agents, in order to ensure the air gap does not change the run-time of the reactor. Core end face quality silicon steel end face gum, silicon steel plate firmly together, greatly reduced running noise, and has good corrosion resistance. Coil winding-inclusive structure, the main coil insulation glass fiber impregnated with epoxy resin, heat drying after curing under vacuum dip high temperature insulating paint, the coil is not only good insulation and high mechanical strength to withstand motor start when the current impact and hot and cold shock without cracking. Conditions of use. Altitude over 1000 meters. 2 Run the ambient temperature is -25 ℃ ~ +45 ℃. Installed in indoor non-violent vibration, no harmful gases or powder dust occasions, non-inflammable and explosive materials. When the starting time of at least 2 minutes (one or more times and) should be cool 6 hours before starting again. Performance parameters dry start reactor than traditional oil-immersed reactors, hollow reactor volume is smaller, with a light weight, small footprint, simple structure, easy installation features. 2 temperature levels reached Class H (180 ° C); during normal operation, the dry type iron core starting reactor core temperature less than 85K, the coil temperature less than 95K. Dry-type starter reactor core loss is less than the loss of the oil-immersed reactors. Dry-type reactor core starter noise is not greater than the national standard (50dB).
