Abstract
A kind of experimental automatic discharge device and method, including discharge insulating rod, metal hook for hanging in discharge point is arranged at the front end of discharge insulating rod, metal hook is connected with metal discharge static contact through insulating discharge wire, metal discharge static contact is fixed, metal discharge rod movable contact that can be up and down telescopic is arranged below metal discharge static contact, recess that is matched with the top of metal discharge rod movable contact is arranged at the lower end of metal discharge static contact, metal discharge rod movable contact is electrically connected with grounding device through wire.Changing the method of original discharge, change into the method of electric control and carry out sparkover discharge, the direction of rotation of motor is controlled by monitoring the voltage value of discharge point of the equipment under test and the current value in discharge circuit in real time, the air gap distance of discharge circuit can be controlled by the method of electric operation in the application, the discharge process is more stable and reliable, the intensity of work of test personnel can be reduced, fatigue work is avoided, and discharge safety hazard appears.
