Details: 1, use AC induction motor starting at rated voltage, the initial starting current is very large, often many times more than the rated current (typically 5-7 times), in order to reduce the starting current, not to cause power grid influence, usually way to start lowering the voltage AC induction motor, commonly used method is the use of antihypertensive reactor or autotransformers, AC motor starting process is very short (typically a few seconds to minutes), starting after the buck Starting with the reactor or autotransformers resection. The product is. Two high-voltage induction motor starting characteristics according to design, structural features 1.QKSC dry-type reactor core starter core quality imported silicon steel core columns into small pieces evenly through multiple gap, the gap isolated as epoxy boards, high-temperature high-strength adhesive and to ensure that the gap does not change the reactor operation. 2 the end face of the core end surface of high quality silicon glue, silicon firmly joined together, which reduces the operation noise, and has good corrosion resistance. 3 coil wrapped structure, the main coil insulation made of glass fiber impregnated with epoxy resin, curing hot baking varnish impregnated with high temperature insulation, the coil is not only good insulation properties in a vacuum, and high mechanical strength, can withstand motor start When a large current impact and thermal shock without cracking. Third, the use of conditions 1. Altitude not exceeding 1000 meters. 2 Run the ambient temperature is -25 ℃ ~ +45 ℃. 3 installed in non-violent vibration within households, without any harmful gases or dust powder occasion, no flammable items. 4 When the starting time of the full two minutes (once or several times the sum), should be cooled six hours before starting again. Fourth, the performance parameters 1 reactor dry starter oil than conventional reactors, hollow reactor volume to be small, light weight, small space, simple structure, convenient installation. 2 temperature levels reached Class H (180 ℃); during normal operation, dry reactor core starter core temperature not greater than 85K, the coil temperature rise of no more than 95K. 3 Dry starter reactor core loss is less than the loss of oil reactors. 4 Dry reactor core starter noise is not greater than the national standard (50dB)
