 SYD1 series wound motor liquid resistance starter cabinet 
 I. Overview: SYD1 series liquid resistance starter is in aqueous solution as a special media resistance. Introduction of plate electrodes in series with the motor rotor circuit, motor starting, driven by a low-power servo motor plate movement to change the relative position of the plate in a specially designed liquid resistance. Liquid resistance from big to small to make the Promise change (in series with the rotor circuit), so that low motor current smooth start. 
 Second, the scope of application: SYD1 series of liquid resistance starter is widely applicable to three-phase AC 50Hz, rated voltage of 380V-10KV in all sectors, 75-10000KW wound rotor induction motor overload smooth transfer start. 
 Third, the performance characteristics: 
 · Soft-start, starting current: Iq ≤ 1.3Ie (A); 
 Can be consecutive start, 5-10; 
 · Low voltage start: when the grid voltage is lower than 10% of the rated motor voltage, and a smooth start; 
 · Start the process smooth start: the impact of mechanical stress on the equipment, extend the machinery and equipment and motor life; 
 · Starting performance far superior to the frequency sensitive rheostat, oil-immersed rheostat, cast iron resistance starter; 
 · Wide applicability, applicable to any load condition, the wound rotor motor soft starter, especially suitable for heavy starting; 
 Start overtime, the super-pressure, over-travel, over-temperature, multiple protection features; 
 · Simple construction, reliable, and all operations automation, installation and maintenance.
