Equipment measures required data.By connection taken amount terminal 1 on simulated failure connecting terminal 5, can with analog power failure, connect
A variety of unusual service conditions such as ground, electronic device failure measure abnormal data, the whether correct output signal of verifying attachment.
The application method of quick switching device for Zero flux CT secondary electron module test wiring, secondary electron module
End plug 3 is docked with the Zero flux CT secondary electron module connecting terminal tested, measuring device end plug 4 and measuring device
Terminals connection, the signal for each terminal of Zero flux CT secondary electron module connecting terminal tested are picked up to taken amount terminal 1
On, pull the i.e. convertible different modes of connection of selection switch 2, data needed for measuring.
That the present invention overcomes previous Zero flux CT secondary electron module test wiring is complicated, time-consuming, equipment easy to damage
Defect.It realizes Zero flux CT secondary electron module to dock with progress plug between testing equipment, avoid in connecing by testing equipment
Line is disconnected on line end repeatedly, need not be powered off when measuring different parameters, change wiring, the selection on trip gear is only needed to switch i.e.
Required parameter can be measured.
