供应JFEM型电机引接线供应JFEM供应JFEM3000V电机引接线3000V电机引接线，工厂负荷分类方式有哪些
What are the types of factory load classification
一级负荷是指，中断供电将造成工艺恶化设备损毁人员伤亡的电力负荷，必须要提供双回路电源来保证，如氯化氢合成反应器及相关控制系统。二级负荷是指，中断供电将造成重大损失的电力负荷，一般最好要提供双回路电源来保证。三级电力负荷指一般的电力负荷，如照明等。 现在化工厂一般对DCS控制系统及现场监控、控制、调节的执行机构都有UPS电源来保证不断电的措施。同时对关键控制阀都可根据工艺要求设置其在失去驱动力后的状态方式。
The first stage load means that interruption of power supply will cause the power load to deteriorate the casualties of the equipment damaged by the process. It is necessary to provide a double circuit power supply, such as the hydrogen chloride synthesis reactor and the related control system. The two stage load is the power load that interrupts the power supply, which will cause heavy losses. Generally, it is better to provide double circuit power supply to guarantee. The three level power load refers to the general electric load, such as lighting. Nowadays, chemical plants usually have UPS power to ensure continuous power for DCS control system, on-site monitoring, controlling and adjusting executive agencies. At the same time, the key control valve can set its state mode after losing the driving force according to the process requirements.
也不要随意拔高负荷的等级，我们有一个项目就是由于业主要求负荷等级为一级，结果造成投资费用的增加，而且还在工期上造成了延长，得不偿失！负荷等级的确定应有相应使用的专业进行制定，不能想当然的确定。
Also do not choose the higher load level, we have a project is because the owner demands the level of load level, the result of the increase in investment costs, and also caused the extension of the time limit, not worth the loss! The determination of load level should be made according to the corresponding professional, and cannot be taken for granted.
安装负荷总是大于计算负荷。因为K小于等于1，只要有电机等感性负载，K一定小于1。电机越多，K越小，计算负荷与安装负荷的差值也越大。
The installation load is always greater than the calculation load. Because K is less than or equal to 1, as long as there are inductive loads such as motors, K must be less than 1. The more the motor is, the smaller the K is, the larger the difference between the calculated load and the installation load.
一般工厂的办公及生活区域的安装负荷可以按每平米用电指标估算，比如办公区30-70W，公寓30-50W等。生产区厂房的安装负荷需要甲方提供具体的用电设备，因为设备的功率大小与厂房的面积大小没有直接联系。尤其是重要的感性负载数量在确定计算负荷时十分重要。感性负载越多，K值选的越小。
The installation load of office and living area in general factories can be estimated according to the electricity consumption per square meter, such as office area 30-70W, apartment 30-50W, etc. The installation load of the workshop in the production area needs the specific electrical equipment provided by Party A, because the power of the equipment is not directly related to the area of the workshop. In particular, the number of important inductive loads is very important when determining the calculation load. The more the emotional load is, the smaller the K value is.
一、符合下列情况之一时，应为一级负荷：
First, the first class load should be one of the following situations.
1．中断供电将造成人身伤亡时。
1. interruption of power supply will cause personal casualties.
2．中断供电将在政治、经济上造成重大损失时。例如：重大设备损坏、重大产品报废、用重要原料生产的产品大量报废、国民经济中重点企业的连续生产过程被打乱需要长时间才能恢复等。
2., interruption of power supply will cause significant losses in politics and economy. For example, the damage of major equipment, the scrap of major products, the discarding of the products produced with important raw materials, the continuous production process of the key enterprises in the national economy have been disorganized for a long time to recover.
3．中断供电将影响有重大政治、经济意义的用电单位的正常工作。例如：重要交通枢纽、重要通信枢纽、重要宾馆、大型体育场馆、经常用于国际活动的大量人员集中的公共场所等用电单位中的重要电力负荷。在一级负荷中，当中断供电将发生中毒、爆炸和火灾等情况的负荷，以及特别重要场所的不允许中断供电的负荷，应视为特别重要的负荷。
3., interruption of power supply will affect the normal operation of power units with significant political and economic significance. For example, important transport hub, important communication hub, important guesthouse, large stadium and large stadium, a large number of public places often used for international activities, such as the important power load in the power supply unit. In the first stage load, the load of poisoning, explosion and fire, as well as the load that does not allow interruption of power supply, should be considered as a particularly important load when the interruption power supply will occur in the case of poisoning, explosion and fire.
