It is advantageous for position determination of fault.
Nowadays, the integral type power type that can export high-voltage pulse is various, and manufacturer includes both at home and abroad, but its control is high
The mode of pressure pulse output is divided into two kinds substantially：A kind of is by the way of contact conducting, i.e., to be entered by exposed copper ball contact
Row is actively touched and exports high-voltage pulse；And another kind is the mode using high-voltage breakdown, i.e. the adjustable ball gap of on-chip power passes through
Boosting punctures ball gap and exports pulse.The first has more controlling compared with the second way above, can be exported by controller
Continuous impulse or individual pulse, second fully relies on and continuously attempts to breakdown fault point voltage, human assistance output, and only
Can be continuous impulse, no control ability.Touched using exposed copper ball contact and more reasonable by the way of being turned on, but because
It is exposed in atmosphere for its contact, on the one hand work long hours, copper ball surface can be caused to form black thin film, conduction is affected
Can, it is on the other hand because copper ball is exposed, exposed equal to high pressure, operationally there is potential safety hazard, electric discharge transient magnetic field is strong, shadow
Ring other normal circuit operations.In a word, there are problems in the current high-voltage pulse way of output.
【Utility model content】
