Width it is adjustable.
According to an embodiment of the present invention, the cylinder connecting rod is telescopic connecting rod.
According to an embodiment of the present invention, the width of the discharging gap is 1mm.
The utility model due to using the technology described above, has the following advantages that it compared with prior art and actively
Effect:
The suspension electrode model for a kind of circuit breaker operation mechanism that an embodiment of the present invention provides comprising insulation connects
There is screw worked itself loose in socket part, high-field electrode, ground electrode and suspension electrode portion, the insulated pull rod that suspension electrode portion is equivalent to breaker
The suspension electrode formed when dynamic, this kind of suspension electrode model are capable of the real work of the insulated pull rod of mimic-disconnecting switch operating mechanism
State can be used in the research of suspension electrode flash-over characteristic in circuit breaker operation mechanism, solve the prior art to floating potential
Strength of discharge adjusts the problem of difficulty and is difficult to the problem of insulated pull rod actual conditions in mimic-disconnecting switch, meets breaker behaviour
Make the needs of suspension orientation discharge characteristic research in mechanism.
