摘要
针对起动器产品存在的问题 ,对原 BQD10系列、BQD15系列起动器产品进行了升级改造 ,采用快开门结构 ,真空电器 ,计算机综合保护等技术改造措施后 ,新系列起动器产品工作电压为 114 0 V,亦可用于 6 6 0 V或380 V供电系统 ,增加了运行前检查试验。进一步满足了煤矿井下控制和监控的需要 ,同时也解决了起动器规格不全引起的使用不合理问题。
The new series starits are brought out through the upgrading of the old series against the existing problems.By adopting the fast on structure,vacuum electrical unit,computer integrated protection for motors,the new series starter can be supplied with 1140V operating voltage,as well as with 660v or 380v,increases test function before runing.so,the new series starters can be met the demand for supevising and controlling under coalmine,along with it,the problems of unreasonable use for the cause of shortage of specifications are solved.
