SYD2 series wound motor Liquid Resistance Starter Cabinet 
 A range of applications 
 Applicable to 3KV, 6KV, 10KV, the power range to high-voltage cage 32000KW even larger capacity (synchronous) step-down motor soft start. 
 Second, the principle 
 SYD2 series of high-voltage squirrel cage (synchronous) electric hydraulic starter solution is used as the resistance of special media, in special boxes designed to introduce high-pressure liquid resistance electrode plates for the string into the stator circuit, motor starting, by a small servo motor drive power to change the plates move relative position of the plate, so that (sub-loop of string meditation) for the non-polar liquids from big to small changes in resistance, so that the motor low current smooth start. 
 Third, the performance characteristics 
 1, the constant current soft-start performance: starting process, the starting current remained unchanged, less than 3 times the rated current; 
 2, the starting power factor is high and approximately constant, usually above 0.75; 
 3, smooth start: the motor starting torque and small to large and gradually increased to a smooth start-mechanical equipment, no impact, no whistle, and the mechanical equipment can smooth over the resonant speed, so that equipment from harm; 
 4, heat capacity, can be 3-5 times consecutive start, will not be burned; 
 5, little impact on the grid, the starting grid when the pressure drop within 5%; 
 6, a sound alarm function and motor protection, safe and reliable; 
 7, simple, reliable, installation, maintenance; 
 Fourth, the technical parameters 
 1, Rated voltage (KV) 3.6, 7.2, 12 
 2, the withstand voltage (KV / Min) 25, 30/32, 38/42 (relatively); 12, 15, 18 (white) 
 3, the starting current ratio 2-3.5Ie 
 4, the starting time (S) 10-60-120 (adjustable) 
 5, electro-hydraulic operating temperature (℃) 0-70 
 6 consecutive start (time) 3-4 
 7, the enclosure protection class IP20, IP30 
 Fifth, the implementation of standards 
 1, 3-35KV AC metal-enclosed switchgear GB3906-1991 
 2, SYQ3 cage (synchronous) electric hydraulic starter Q/XSP3-2002 
 Sixth, use 
 1, ambient air temperature: (-25 - +50) ℃ 
 2, relative humidity: ≤ 90% 
 3, pulling height: ≤ 2000m 
 4, no significant shake installation site vibration and shock; non-corrosive gases; install tilt ≤ 5 °
