Therefore, in order to guarantee the stability of production, but also to reduce the actual running costs, heat-conducting oil bellows system should be chosen cut-off valve can not be selected filler valve seal or valve.

因此，为了保证生产的稳定，也为了降低实际运行成本，导热油系统应该选用波纹管截止阀，不能选用填料密封的截止阀或闸阀。

004 The brake shall be adjustable in height so that it can block wheels of different diameters and in width to grip rims of different thickness.

That is to say, during the starting process of induction motor, hold-off angle of current has gradually decreased from initial value to zero. The method can always make the displacement angle less than thyristor's firing angle. So the voltage of the induction motor won't oscillate. Therefore, the oscillation of current, electromagnetic and speed can be eliminated during the soft-starting process of induction motor. This paper verifies the correctness of the method by simulation at first.

根据上述原因，本文提出了采用关断角控制的新型控制策略，这种控制策略是使电动机在起动过程中的电流关断角由某一初始值逐渐减小到零，利用该方法可以使感应电动机起动过程中的续流角始终小于晶闸管的触发角，这样续流角的变化就不会引起电动机端电压的振荡，因而就从根本上消除了感应电动机软起动过程中的振荡现象。
