qxq磁控式软启动器做工精细,外观合理,质量上乘（Qxq magnetron type soft starter, fine workmanship, reasonable appearance, high quality） QXQ magnetically controlled soft starter, exquisite workmanship, reasonable appearance, high quality I. scope of application: Three phase 50HZ, rated voltage 0.4KV, 3KV, 6KV, 10KV, rated power 100-30000KW, all kinds of load squirrel cage asynchronous (synchronous) motor Two, working principle: Principle: the closed loop control system, adjust the size of the magnetic flux change, smoothing reactor inductance, the inductance decreases from large to small automatic continuously in the predetermined time, the motor soft start. Composition: the product unit consists of three parts: A, high voltage work winding; B, a synchronous adjustment mechanism for the magnitude of magnetic flux C and two control loops. The working process is as follows: before the motor starts, the starting parameters are set through the man-machine interface, and the desired starting current is written into the magnetic control controller. When the motor starts, by adjusting the size of the magnetic flux, smoothly change the reactor inductance, the inductance decreases from large to small automatic continuously in the predetermined time, the motor soft start. Three, performance characteristics 1, through the mechanical synchronous drive change xigangpian magnetic direction and size of the air gap flux adjustment control 2 、 adopting the leading computer simulation technology in China to make the whole starting process predictable, controllable and adjustable; 3 、 three starting current curves can be selected: constant current, slope and sudden jump to meet the requirements of different working conditions; 4 、 friendly man-machine interface, starting parameter setting, adjusting flexibly, convenient to inquire the history curve; 5 、 starting current can be arbitrarily chosen at 1.5Ie - 3.5Ie (depending on the load). When starting, it can ensure the minimum voltage drop of the power grid,
