SYD3 series of high-voltage liquid resistance cage motor starter cabinet 
 A range of applications 
 Applicable 3KV, 6KV, 10KV, power range to high-power high-voltage cage even 32000KW (synchronous) step-down motor soft start, soft stop and protection. The device is widely used in building materials, metallurgy, petroleum, pharmaceutical, water conservancy, electric power, chemical industry, fans, pumps, compressor start. 
 Second, the principle 

 SYD3 series of high-voltage cage (synchronous) electric hydraulic starter solution is used as the resistance of special media, in a specially designed high-pressure fluid resistance box in series with the introduction of the electrode plate for the stator circuit, motor starting, by a small power servo motor moves the plate to change the relative position of the plate, so that (sub-loop of string meditation) for non-polar liquid resistance from big to small changes, so that the smooth motor starting current low. 
 Third, the performance characteristics 
 1, the constant current soft-start performance: starting the process of current remained unchanged at 1.5-3.5 times the rated current; 
 2, the starting power factor is high and approximately constant, generally above 0.75; 
 3, heat capacity, continuous 3-5 start, will not be burned; 
 4, starting smooth: small to large motor starting torque gradually increased, the machinery and equipment start-smooth, non-impact, no whistle, and mechanical equipment can smooth over the resonance speed, the equipment from harm; 
 5, a small impact on the grid, starting when the grid voltage drop less than 5%; 
 6, a sound alarm function and motor protection, safety and reliability; 
 7, the structure is simple, reliable, installation and 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, starting current multiple of 2-3.5Ie 
 4, start time (S) 10-60-120 (adjustable) 
 5, the electro-hydraulic operating temperature (℃) 0-70 
 6 consecutive starts (times) 3-5 
 7, the enclosure protection class IP20, IP30 
 Fifth, the implementation of standards 
 1, 3-35KV AC metal-enclosed switchgear GB3906-1991 
 2, SYD3 cage (synchronous) electric hydraulic starter Q/XSK3-2004 
 Six conditions of use 
 1, ambient air temperature: (-25 - +50) ℃ 
 2, relative humidity: ≤ 90% 
 3, altitude: ≤ 2000m 
 4, the installation site without significant shake and shock and vibration; no corrosive gas; install gradient ≤ 5 ° 
 Seven, ordering instructions 
 * Provide motor type, rated power, rated voltage, rated current, the stator connection (Y, △) star point can open; 
 * Provide drag motor load characteristics, working conditions described;
