ZR-BPYJVP3交联聚乙烯绝缘聚氯乙烯护套铝聚酯复合膜绕包屏蔽变频电力电缆。1、产品执行标准:MT2、用途:本产品适用于交流额定电压u0/u为450/750V及以下的控制监控回路及保护线路和配电装置中电器仪表的连接线。
YKM:星型启动时吸合,切换三角形时不吸合middot;KM:星型启动时不吸合,切换三角形时吸合我们要记住星三角起动过程:1.按下起动按钮2.主KM和YKM接触器吸合,星型起动3.经过时间继电器延时4.切断YKM,并接通△KM,切换到三角型.通电延时型时间继电器:通电后,在设定的时间后才动作,和接触器一样,有线圈,常开触点,常闭触点,但这种通电延时型,不是立刻动作,而是在你设定的时间后才动作。:设定3秒,线圈通电后,常开常闭触点不会立刻动作,要3秒钟时间到了才动作。
???? In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 8.7/15 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t1765650.1.2. In this way, the overall level of the company's cross-linked power cable is lower than the domestic status. This company produces the type refractory power cables for rated voltage 0.6/1 kv copper core cable, can also produce low smoke zero halogen fire-resistant power cable, high flame retardant fire-resistant power cable oxygen insulation layer, the fire-resistant performance in line with the GB/T12666.6 cable fire resistance test. Therefore, the overall performance of refractory series power cables is good and reliable. The water resistance performance of fireproof cable conforms to iec 502-2.
本产品适用于石油、化工等部门的本质安全型设备及系统,它不仅能靠地传输微弱的模拟信号和数字信号。而且电缆的抗干扰性能高、电气性能稳定。保证了传输信号参数的准确性和控制系统的安全运行。2、产品使用特性:电缆导体的长期允许工作温度应不超过70℃。

SB1是总停开关,按下SB1导致接触器线圈KM1断电,这将导致线圈KM2通电,线圈KM3断电。主电路中因主触头KM1,KM3断电.KM2通电,转子上施加了反转转矩,导致电动机M快速降速。当电动机快速降速至速度继电器KS的额定转速时将断开,电动机停转。本控制线路中,共有四个回路:A——1——2——3——B——CA——1——4——5——6——B——CA——1——7——8——9——B——CA——1——10——11——12——B——C程序所示为根据逐行回路转换法得到的初步转换梯形图,该图直接将四个回路转换为一个四行的梯形图,但初步转换梯形图还须根据梯形图若干绘制原则进行合理修改。
