Main flameproof motor vehicle batteries Division dedicated controller scope and working conditions: QKT27-100 / 250 mine general type driver controller (the old model QKT27-2 / 2TH) for 3 t rack wire resistive speed locomotives, As the locomotive speed start, stop, reverse purposes. Which QKT27-2 general type, QKT27-2TH for warm type. The driver controller for the following environments: an altitude of no more than 1200M (more than consultation with users). 2, the ambient temperature is -20 ℃ - + 40 ℃ (monthly average temperature of + 25 ℃ when). 3, ambient air relative humidity less than 90%. 4, no flammable gas and coal dust explosion sites mixture. 5, not enough to destroy harmful gas insulation and corrosion of metals. 6, there is the rain, snow, splash protection devices. 7, is inclined with respect to the normal position within 10 degrees of the case 8, with respect to the longitudinal direction of the locomotive having not more than 30m / s2 impact acceleration. 9, with respect to the locomotive vertical, horizontal and vertical sinusoidal vibration with a frequency f 2-50HZ, the amplitude A is not greater than: 2≤f≤10HZ A = 25 / f (mm) 10≤f≤50HZ A = 250 / f2 (mm) 10, mounted on the battery type XK3T mining electric locomotive driver control room. Technical parameters: 1, Rated voltage: 250V (DC); 2, rated current: 100A; 3, contact the contact surface not less than 80% of the total length of the contact direction. 4. Align the contacts and the contacts do not differ more than 1mm. 5, contact opening distance> 8mm. 6, the beginning of the contact pressure> 14.7N 7, contact final pressure> 29.4N at the forefront of technology, manufacturing equipment to create a generation of famous Hengtai Company Name:!
