Detailed Description

WYQ8 Liquid State Soft Starter for Slip-ring Motor I. Application Applied for Slip-ring Motor overload smoothly soft start are which three phase current 380V,660V,3KV,6KV,12KV, power rating 45~10000KW. .II Working principle The controlled of wound-rotor asynchronous motor rotor loop in series with the three-phase star connection liquid resistance, fluid resistance with starting motor and automatic input, resistance will be stepless reduced within predetermined time, close to zero automatic excision, thus motor access rated current and maximum torque circumstances no impact on the smooth start-up. III. Main features: The Soft Starter for Slip-ring Motor body and water tank adopts full-closed structure, which can avoid too fast evaporation of the electrolyte, prolong the life span of starter, reduce the maintain frequency. Especially suitable for places where the annual rainfall amount is less than 200 mm Soft Starter for Slip-ring Motor is equipped with circulator, special natural circulation cooling system can make the heat from the water tank emit quickly Especially suitable for continuous start in a certain time. Adopts worm lifter, steady, reliable and no noise. Small start current, less than 1.3 times of the rater motor Can be started for 5-10 times in succession Smoothly start, no shock of mechanical stress, prolong the life span of motor and equipments Can be started with a low voltage, 6 KV motor is 5.5KV, 380V motor can start with 340V Reliable structure, automatic operation, easy to install and maintain. IV. Standards Low voltage set switch equipment and control equipments:GB7521.1-1997 IEC439-1 :1992 WYQ Liquid resistance starter: Q/XWZ2-2000 Place of Origin Hubei, China (Mainland) Brand Name Worldsure Model Number WYQ8 Motor power 75-10000 KW Frequency 50 / 60 Hz Voltage 380V -10 KV Environment temperature -40 - 50 Protection Grade IP20 IP30 start time 10~60s start current Iq< 1.3 Ie(A) start times 5-10 times in succession standard 1-1997 IEC439-1 color negotiatable
