Breakdown, to improve the high current breaking capacity of vacuum interrupter, but do not have to the insulate improvement of resistance to voltage levels of vacuum gap
Apparent effect.
Spark ageing is to apply high voltage to vacuum interrupter under quiescent conditions, cause between the contact of vacuum interrupter,
Spark discharge between contact and shielding case causes enhancing transmitting by the field that contact and bucking electrode surface are removed in spark discharge
Point, to improve vacuum insulation grade.Since traditional spark ageing technology has that discharge energy, discharge frequency are lower,
The raising of production efficiency is constrained, for this purpose, (Wang Weibin, Yang Lanjun, Feng Yunping improve vacuum interrupter ageing effect to document
Several new method [J] High-Voltage Electrical Appliances, 1999,35 (3): 40-44) a kind of high frequency ageing device of vacuum circuit breaker is proposed, have
Body is that the high frequency damp oscillation in vacuum interrupter both ends shunt capacitance, inductance series arm, after being punctured using arc-chutes is caused
Repeatedly breakdown, to improve the discharge time and ageing efficiency in the unit time.Due to during discharge, the electricity of vacuum gap
Flowing through zero Quench, there are biggish randomnesss, meanwhile, the frequency and damping characteristic of discharge process are influenced by loop parameter
Larger, therefore, discharge time, impulse discharge energy and contact ablation degree in the unit time are difficult to accurately adjust, and cause
Ageing degree, trend and ageing consistency are difficult to effectively control.

Development [J] High-Voltage Electrical Appliances, 2004,40 (4): 301-303..), in addition, being exported back since single pulse energy is larger in power supply
When road carries out current limliting and ageing energy adjustment using series resistance, the peak value of output voltage can be influenced simultaneously, therefore, adjusted
There are biggish technical limitations for mode.
In conclusion there are following main problems for ageing technology at present: electric current and voltage ageing effect cannot be combined effectively；
Breakdown voltage and ageing energy, technical difficulty and higher cost are provided with single power supply, while single ageing energy can not be accurate
It adjusts, ageing degree, trend and ageing consistency is caused to be difficult to effectively control.
