жидкость стартер, стартер жидкость сопротивление

Range of application It is applicable to the heavy load smooth soft starting of coiling ac asynchronous motor that is of three phase AC 50Hz 60Hz,rated operation voltage of 380V 10KV,rated power of 75KW 10000kw,especially in industrial and mining establishments with unstable or low voltage Operation principle Special made electrolyte is put in the rotor loop of the controlled coil motor as the resistor ,and by adjusting the density of the electrolyte and the distance between the two plate electrodes to ensure that the input resistance can meet the requirements of the motor’s mechanic characteristics in the starting process, so as to make the motor rise speed equally with maximum starting torque and minimum starting current ,and make a smooth starting ,when starting is over ,the electric switch shorts the rotor loop Main performance and characteristics Soft starting ,small starting current: Iq ≤1.3Ie(A) reduces motor starting temperature rise, effectively lengthened the motor’s service life: * smooth starting, no shock to the mechanical equipments: * can make continuous starting for 5 10 times, starting performance is better than frequency sensitive starter; * low requirement for the power grid, no harmonic wave to affect the power grid; * structure is reliable, simple .convenient for installation and maintenance; * good uniformity ,applicable to coiling motor soft starting under and load situation ,specially suitable for heavy load starting; * has multiple protection function like starting overtime, over stroke and over temperature * when used in cold areas of the north, the equipments is equipped the self-heating function. Main technical parameters *starting initial current :Iq≤1.3Ie(A) *starting times:10-60s,presetting ,adjustable on site *starting times: continuous starting 5 10 times *normal operation temperature of electro hydraulic: *Shell protection grade: IP20, IP30 Standards of conformity *GB7521.1-1997IEC439-1:1992 *Q/XWZ2-2000 TYPE External Dimension (MM) Installation dimension (mm) A B C D E WYQ7-0.2 700 710 1800 600 585 WYQ7-0.4.0.6 800 760 2000 680 640 WYQ7-1 1060 960 2000 960 835 WYQ7-2 1200 960 2000 960 835 WYQ7-3 1300 1060 2200 1200 935 WYQ7-4 1300 1260 2200 1250 1150 WYQ7-5 1400 1260 2200 1350 1150 WYQ7-8 1800 1460 2200 1750 1350 WYQ7-10 2000 1660 2200 1950 1550
