5.4.2 Power Supply
The basic requirements for the electrical facilities of the plant are described hereafter.
1) The 380V distribution system will be double radial type.The above systems will be sectionalized by the tie circuit breaker.
2) Each transformer in the dual radial system will be capable of supplying 100% normal running load.
3) The 380V bus tie breaker will normally open and the system operates as two systems,but the two transformer will not operate in parallel.
4) Bus tie breaker iselectrically interlocked with circuit breakers,so that it can not be closed unless one of the incoming breaker is open.
5) When one of the incoming feeders trips,the 380V bus tie breaker is closed automatically with delayed action by means of the other incoming feeder is capable of carrying the entire load current and sufficient switch gear capacity is provided.
6) Automatic transfer system for 380V critical loads are fed from diesel generator when there is a power failure on the bus bar.The automatic starting time of the diesel generator has been foreseen approx.15 seconds after input starting order.
Power supplied and sent to the B/L by the Buyer is as follows:
Driving power 380V?5% 50Hz 3 phase AC
Lighting power 380V/220V?5% 50Hz AC
Instrument power 110V 50Hz 1 phase AC
Motors' power is directed supplied by MCC in which short circuit and over-load protections are provided.It required,each motor can be started and stopped at field or remotely controlled.Its power is from its motor circuit.
There is a set of power condenser in the proposed plant.It makes the power factor reach 0.9.All electrical equipment and materials are designed to meet anti-corrosion requirements in the plant.

5.4.2电源供应器
为工厂的电力设施的基本要求是描述以下.
1）380伏配电系统将双径式.上述系统将分段断路器的配合.
2）中的每一双径向系统变压器将供应100％正常运行负荷的能力.
3）380巴士配合断路器将常开和系统运行两个系统,但两个变压器不会并行工作.
4）巴士配合断路器iselectrically联锁断路器,因此,它不能,除非传入断路器一个封闭是开放的.
5）当输入的车次馈线之一,380总线配合断路器关闭与其他进线方式自动推迟行动是贯彻整个负载电流开关齿轮承载能力和足够的提供能力.
6）自动转换为380伏关键负载系统的柴油发电机供电的时候有一个母线停电.自动启动了柴油发电机的时间已经预见到约. 15秒后输入出发顺序.
电力供应和派出由买方到B / L是如下：
驱动功率为380V?5％,50赫兹三相交流电
照明功率380V/220V?5％,50Hz交流
仪表电源110V三相交流50赫兹1
