JYP2V-1JYP2V-2JYP2V-3多对屏蔽控制电缆电子计算机(包括DCS系统)用多对屏蔽控制电缆执行标准:企业标准(等效采用英国BS5308—86)用途:适用于发电、冶金、石化等上矿企业集散系统、电子计算机系统、自动化系统的信号传输及检测仪器、仪表等连接用多对屏蔽电缆。

电缆线芯之间,线芯与屏蔽之间能承受交流50HZ1000V电压试验5min。电缆任一绝缘线芯在IKHz时的工作电容不大于200nF/KM。电缆任一绝缘线芯的电感与电阻之比均不大于50uH/Ω。辐射电磁场在频率20-200MHz的范围内,场强为120dB(7mv)的电磁场中,电缆线芯内感应强度小于50dB。
令牌总线通讯方式令牌总线通讯方式又称为N:N通讯方式是指在总线结构的PLC子网上有N个站,它们地位同等没有主站与从站之分,也可以说N个站都是主站。N:N通讯方式采用令牌总线存取控制技术。在物理总线上组成一个逻辑环,让一个令牌在逻辑环中按一定方向依次活动,获得令牌的站就取得了总线使用权。令牌总线存取控制方式限定每个站的令牌持有时间,保证在令牌循环一周时每个站都有机会获得总线使用权,并提供优先级服务,因此令牌总线存取控制方式具有较好的实时性。
Purpose of HYAT solid insulated filled cable: solid insulated filled cable is suitable for the urban telecommunication line of the local telecommunication network in the town of wuyu, and also for the special network line connecting to the public network. Mainly used for pipeline laying. The inner and outer surfaces of the cable core and the shield layer are filled with oil paste and poured to prevent water intrusion. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C. Structure: wire: annealed bare copper wire, copper wire diameter 0. 32, 0. 40, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 (mm). Insulating material: high density polypropylene or polypropylene, colour of the insulated wire as indicated by full chromatograph. Pair of insulated wires: twist two different colored insulated wires into pairs at different pitch and use the specified chromatographic combination to identify pairs. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs of cables with more than one pair of cables plus 1% of the reserve pair, but not more than 6 pairs. The gap in the core is filled with oil paste. Core tape: wrap with a polygrease film tape. Shielding: metal strip with or without striping, which is longitudinal wrapped outside the core of the cable. Sheath: black low density polymer. Double sheathed cables can also be provided. Identification and marking: cable outer surface sexual 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, but with the tag stagger. Other structures: according to the needs of users, we can provide armored cables HYAT53, HYAT55 and high frequency isolation cables YATG with strengthened mechanical protection layer.

2.电缆耐火防护电缆数量较少时,可用防火涂料、包带加于电缆上或把电缆穿于耐火管。同一通道中电缆较多时,宜敷设于耐火槽盒内,且对电力电缆宜用透气型式,在无易燃粉尘的环境可用半封闭式,敷设在桥架上的电缆防护区段不长时,也可采用阻火包。
低压整流滤波电路的原理是什么?答:低频脉冲直流电经过二极管整流后,再由电解电容滤波,这样,输出的就是不同电压的稳定的电流了。由于这里电压已经很低了,所以尽管电容容量很大,通常有1u22uf等,但由于不需要很高的耐压值,所以电容体积很小。辅助电路有什么作用?答:3V直流电通过辅助电源开关管成为脉冲电流,通过辅助电源变压器输出二组交流电压,一路经整流、三端稳压器稳压,输出+5VSB,加到主板上作为待机电压;另一路经整流滤波,输出辅助2V电源,供给PWM等芯片工作。
计算机电缆用途:本产品广泛地应用于发电、冶金、石油、化工、轻纺等部门的检测和控制用计算机系统或自动化装置、以及一般的工业计算机上。使用特征:额定电压UO/U为300/500V。允许工作温度不超过70℃,敷设温度不低于0℃,允许弯曲半径应不小于电缆外的12倍,软结构电缆应不小于电缆外的8倍,铜带屏蔽的电缆应于小于电缆外径的15倍。
