常规放电状态检测方法由于仅采用单一的特征量进行状态判别，因此在加工信号频率高、加工波形产生畸变的微细电火花加工中，不再适用。
Conventional discharge condition detection methods extracting only certain eigenvalue are not suitable for the Micro-EDM due to the high frequency and distortion of voltage wave shape.
它可把火花放电频率控制在允许范围内。
It may limit the amount of sparkover to an acceptable rate .
当火花出现频率较高时，进料振槽停止工作，并且在出料槽内的分料风门，从火花探测器得到一个信号，并被打开。
When high level sparks are detected, the infeed conveyor is stopped, and the product reject flap in the discharge chute is opened by a signal from the spark detector control unit.
