Abstract In order to seek the effective magnetic arc control method, the synergy effect in multi-break VCBs is proposed and the demand of the magnetic arc control of the multi-break VCBs which is the synergy interaction between the dynamic voltage distribution (DVD) and dielectric recovery strength (DRS) is analyzed. Based on the synergy effect, the test platform of the magnetic arc control in multi-break VCBs was set up and the magnetic arc control system was designed. The influence of the pulse width, control moment and magnetic field on the vacuum arc development and the post arc characteristic was investigated. The even DVD was supposed as control target, the effect of the different combinations of external AMF on the DVD was conducted. The influence of the magnetic arc control on the vacuum arc development, the post arc characteristic and DVD was obtained. The test results indicate that the mechanism of the magnetic arc control in multi-break VCBs is that the magnetic arc control affects the vacuum arc, current zero and post arc characteristic and then the DVD and DRS is affected by the post arc characteristic. The paper is useful to optimal design for the special serial VCBs and the magnetic arc control of multi-break VCBs.

Key words： Multi-break VCBs magnetic arc control post arc current synergy effect
