目前,我局各矿所用的电机综合保护器和低压漏电闭锁装置,都是分別安装使用的。这样,不仅在使用上比较麻烦,对于维修和安装也很不方便。并且由于两套装置各用一套电路和结构,故成本也较高。我们参考了国内外有关保护器的电路和结构,对保护器进行了适当的改进,使之具有漏电闭锁功能,从而克服了上述缺点。本保护器经过在井上、下进行工业性试验,效果良好。 At present, all the mines used by our bureau are equipped with integrated motor protectors and low-voltage earth leakage locking devices. In this way, not only is it troublesome to use, but also inconvenient for maintenance and installation. And because the two sets of devices each use a circuit and structure, so the cost is higher. We refer to the circuit and structure of the protector at home and abroad, the protector has been properly improved, so that it has a leakage lock function, thus overcoming the above shortcomings. The protector after the well, under the industrial test, the effect is good.
