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 starters for three-phase AC 50Hz, rated voltage 380V-10KV in all sectors, 75-10000KW overloaded smooth transfer of the wound rotor induction motor starting. 
 Third, the performance characteristics: 
 ? Soft-start, starting current: Iq ≤ 1.3Ie (A); 
 ? Can start 5-10; 
 ? Low voltage start: when the grid voltage is lower than 10% of motor rated voltage, the smooth start; 
 ? Starting process smooth start: the impact of mechanical stress on the equipment, extend the machinery and equipment and motor life; 
 ? Starting performance is far superior to the frequency of the rheostat, oil-immersed rheostat, cast iron resistance starter; 
 ? Wide applicability, applicable to any load condition wound motor soft starter, especially suitable for heavy start; 
 ? With start timeout, overpressure, over-travel, over-temperature and other multiple protection features; 
 ? Simple structure, reliable, and all operations automation, installation and maintenance.
