利用电加温线进行蔬菜育苗是一项新技术。在苗床加温过程中,有时会因断线而影响生产,断线原因只要不是将加温线误接在380伏的电压上烧毁或绝缘层大面积老化,均可修复使用。 一、断线的查找方法 新的电加温线出现断线,一般多因在铺线或起线过程中拉力过猛以及作业时碰上刃器而造成的。这种断线情况显而易见。但是,当外表绝缘层没断而蕊线折断时(尤其是单根蕊线),这种情况可用手指从线的一端慢慢地向另一端理线。
The use of electric heating line for vegetable nursery is a new technology. In the seedbed heating process, sometimes because of broken lines affect the production, broken line as long as the heating line is not mistakenly connected to the voltage of 380 volts burned or insulation aging large area, can be repaired. First, broken search method The new electric heating line appears broken, mostly due to the laying of the line or in the process of pulling too hard and hit the blade operation caused. This disconnection is obvious. However, when the outer insulation is not broken and the core is broken (especially a single core), it is a good idea to use your fingers to gently line one end of the wire to the other.
