我厂1987年自法国EIMCO-SECOMA公司购进的HELIOS12-E50型电动凿岩台车,是价格百万元以上的井下采矿贵重设备,电动机功率50马力(～37千瓦),主回路(380伏)采用LC1 D803E交流接触器控制。该接触器为积木式卡装结构,吸引线圈电压48伏,但使用未及一年,因主触头烧环而报废,不仅无备件可换,而且市场亦无货,采矿生产因此受到严重影响。为让台车能继续运行,保证生产不间断,只有设法用国产接触器代替。首先,考虑到国产CJ_(10)-100/3接触器的容量基本相当,其可控制的电动机功率达到380伏、50千瓦,可供代用,但体积相比之下较LC1 D803E大了许多,
HELIOS12-E50 Electric Drilling Trolley purchased from EIMCO-SECOMA in France in 1987 is a precious metal mine with a price of more than one million yuan. The power of the motor is 50 hp (~ 37 kW), and the main circuit (380 V ) LC1 D803E AC contactor control. The contactor is a building block card-mounted structure, to attract the coil voltage of 48 volts, but the use of less than a year, due to scrap the main contact ring, not only spare parts can be exchanged, and the market is also out of stock, thus seriously affecting the production of mining . In order to allow the trolley to continue running, to ensure uninterrupted production, only to try to use domestic contactor instead. First of all, taking into account the capacity of the domestic CJ_ (10) -100/3 contactor basically the same, the controllable motor power reached 380 volts, 50 kilowatts, can be used as a substitute, but the volume compared to LC1 D803E much larger,
