    Three-phase isolation transformer in operation, the no-load loss will hinder the development of energy-saving. In advocating the saving energy and reducing consumption today, how through the design, installation and use of to achieve the purpose of economic operation, worthy of our study.

    全面开展三相隔离变压器经济运行,不仅是运行部的事,也与设计以及制造厂商有着密切的联系。在三相隔离变压器设计之初就应,先充分考虑三相隔离变压器的经济运行条件。制造部门,则应根据三相隔离变压器不同荷载性质,平衡效率与能耗之间的关系。怎样按经济运行、条件合理的使用三相隔离变压器,这些都属于科学管理的范畴。

    To carry out a comprehensive economic operation of three-phase isolation transformer, is not only the operation Department, also has a close connection with the design and manufacturer. At the beginning of the design of the three-phase isolation transformer should be fully considered, the first three-phase isolation transformer economic operation conditions. The manufacturing sector, it should be according to the different nature of three-phase isolation transformer load, balance the relationship between efficiency and energy consumption. How according to the use of three-phase isolation transformer economic operation, reasonable terms, these all belong to the category of scientific management.

    在实行科学管理时,应不断改变陈旧、不科学的计算方法,改善阻碍生产发展过程中不合理的经济政策。这需要对三相隔离变压器更新的观点和对电价制度有更科学的管理制度。

    In carrying out the scientific management, should continue to change the old, calculation method is not scientific, improve the production process does not hinder the development of rational economic policy. This need for three-phase isolation transformer update views and on the price system is a more scientific management system.

    在电力设计中,三相隔离变压器容量的确定,一般都是根据负载曲线以及负载性质决定的。也就是说,三相隔离变压器的利用率是设计的基础。根据我国节约能源的要求,在设计中不仅要考虑三相隔离变压器的使用容量,还要考虑运行的有效率。根据负载来选择变压器容量,尽量使变压器运行时,有功功率损失和无功功率损失是最低的。在设计中,按容量的利用率和经济运行来选择三相变压器容量,在有些情况下所得的结果是不一致的。通常 ,按变压器容量利用率选择的容量要小一些,然而按经济运行选择的容量则要大一些。对于矛盾的出现,应充分权衡利弊。

    In electric power design, determine the capacity of three-phase isolation transformer, generally is determined based on the load curve and load properties. That is to say, the use of isolation transformer three-phase rate is the foundation of design. According to China's energy conservation requirements, in the design should not only consider the use of three-phase isolation transformer capacity, but also consider the running efficiency. According to the load to select transformer capacity, try to make the transformer operation, active power loss and reactive power loss is the lowest. In the design, according to the utilization and economic operation capacity to choose the three-phase transformer capacity, in some cases, the obtained results are not consistent. Usually, according to transformer capacity utilization rate selection capacity to be smaller, but according to the economic operation of the capacity to choose some. For the emergence of conflicts, should fully weigh the advantages and disadvantages.
