以往我们在钻机机场照明全部使用交、直流发电机(以机场柴油机为动力),因为发电机设有整流子,炭刷等部件,在运转中故障较多。自我们采用三相异步电动机并接移相电容器,利用机场柴油机做动力,在机场照明多年,发电安全可靠、断路后不发电,灯光自熄,维修简单,使用方便,并能够驱动手电钻和砂轮机等机械,从未因晚间照明而停工。电动机型号:J02—42—4;功率:4.5～7kW;接线方法:Y型;移向电容器规格:YY 0.4—12—3(额定电压:0.4kV,容量:260μF,频率:50HZ)。 In the past, we used all the lighting at the airport drilling rig, DC generator (powered by the airport diesel engine), because the generator is equipped with commutator, charcoal brush and other components, more trouble in operation. Since we use three-phase asynchronous motor and phase shifting capacitors, the use of the airport diesel engine power, lighting in the airport for many years, safe and reliable power generation, power generation after shutdown, self extinguishing light, simple maintenance, easy to use, and can drive hand drill and wheel Machine and other machinery, has never stopped due to night lighting. Motor type: J02-42-4; Power: 4.5 ~ 7kW; Wiring method: Y type; Moving capacitor specifications: YY 0.4-12-3 (Rated voltage: 0.4kV, Capacitance: 260μF, Frequency: 50HZ).
