Abstract: In order to guarantee the normal operation of the high gradient magnetic separators, the core components-excitation winding must be offered for water protectionWith reasonable conjunction of water level sensors and detection amplifier circuit,a multichannel and non-interference protective device of cooling water could be set at the outfall of coilsWhen the shortage of water supply appeared in any inlet pipe,an alarm signal would be sent out immediatelyThis step could make the main control loop rupture the current provided to the excitation winding so that the coils would not be burnt due to over temperature
