宜宾变压器的直流宜宾变压器充、退电电路     宜宾变压器的直流宜宾变压器充、退电电路
    控制原理通常直流宜宾变压器充、退电电路由两只直流接触器分别提供正反向电流来完成。图1接触器控制充/退电电路图1是陶瓷压机上模具直流宜宾变压器控制电路,图中,KM5.1和KM5.2是两只直流接触器,分别控制充电和退电,但在更换模具时经常出现接触器触点因电弧烧坏现象。
    采用有限元的方法对铁的电场进行了分析，并利用ANSYS软件进行了模拟电场的计算，获得了电场的分布。然后根据电路和电场两个方面的计算结果，采用外点惩罚法对铁进行了优化设计。
    80年代以来,国外已采用集成电路控制宜宾变压器的充退电以求取得更佳退电效果,如美国O·SWAIKER 公司推出的宜宾变压器控制器不但用于美国BS 公司的,也为日本的okamoti 公司采用。上海机床厂从1982年开始设计集成电路充退电装置。
    The control principle of usually DC magnechuck charge the demagnetization circuit consists of two DC contactor to provide positivenegative current. Figure 1 contactor control charge / demagnetization circuit diagram of a ceramic press mold DC electromagnetic sucker control circuit diagram, the KM5.1KM5.2 is two DC contactors, respectively, to control the magnetizationdemagnetization, but in the replacement of mold frequent contacts of the contactor arc burn out phenomenon.
    Using the finite element method on the magnetic field of the electromagnet,the use of ANSYS software simulation calculation of the magnetic field, the distribution of the magnetic field. According to the calculations of the magnetic circuitmagnetic fields are two aspects, the outer point penalty on the electromagnet has been optimized.
    Since the 1980s, foreign IC to control magnechuck charge demagnetization in order to obtain better demagnetization effects, such as the United States O · SWAIKER company launched the suction controller, not only for the BS surface grinder, but also for Japan''s okamoti adopted. Shanghai Machine Tool Works in 1982 began to design integrated circuits charge demagnetization device.
