HYAC- cableway communication cable - detailed introduction of chromatographic combination for identification. Self-supporting cable core structure: taking 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, and each unit is designated as the unit binding band of chromatogram in order to identify different units. 100 pairs or more of cables plus 1% of the reserve pair. Self-supporting cable core tape: wrapped with polyester film tape. Self - bearing cable shield: with or without corrugated metal strip longitudinal package cable core belt, both sides lap. The plastic film coated on the surface of the shielding belt and the bonding of the protective layer claim to be cable sheath: black low density polymer. Messenger messenger wire: suspension wire for 7 strands galvanized steel ridge, nominal diameter of 6.3 mm and 4.75 mm, its tensile strength is not less than 3000 kg and 1800 kg respectively, suspension wire with thermoplastic paint coating, to prevent corrosion of steel wire. Messenger cable identification and marking: cable exterior sex identification mark, mark at no more than alternate 1 m intervals, tag contents are: the diameter of wire, line number, cable type, factory name and year of manufacture, marking at no more than alternate 1 m intervals to mark on the surface
下面讲解控制回路：首先将DZ108-20空开的绿色按钮按下，此时用物体靠近光电开关，小型中间继电器得电吸合，使其本身常开触点闭合，控制回路电流导通，接触器吸合，从而三相异步电动机运转，运行指示灯点亮。当物体离开光电开关，小型中间继电器失电断开，使其本身常开触点断开，控制回路电流断开，接触器随即断开，三相异步电动机停止运转，运行指示灯熄灭。如果三相异步电动机超负荷运转导致电流过载，空开就会自动断开，此时，红色按钮进去，绿色按钮弹出来，控制回路断开，同时三相电随即断开，电动机停止运转，起到过载保护功能，此时，空开常闭点闭合，跳闸报警指示灯报警，通知用户此回路出线问题。
