Goat's horn insurance fault handling method with insert insure similar.
3, low-pressure plastic shell circuit breaker fault
Typical low pressure fault handling training platform loosens by moulding pile crown splicing ear on shell main breaker 1, the low tension switch fault that simulated field causes because of consumer overload.When student processes this fault, shell main breaker (user's internal electric source inlet wire master switch) is moulded in disconnection, and by field condition, it is normal that breaker of plastic casing inlet wire side voltage measured by application multimeter, outgoing line side voltage is 0V, can tentatively judge to mould the tripping operation of shell main breaker.To mould shell main breaker reset button to reset, switch is sent in examination, normally can power transmission.If abnormal, mains side, for using acceptable safety protective articles, disconnects by treating method, after changing fault breaker of plastic casing, and power transmission.For subsequent usely mould shell main breaker if do not have, consider that repairing recovers power transmission, will can mould shell main breaker about 1 terminal respectively with the interim short circuit of fuse temporarily, recovery power transmission, and then change isolating switch.
4, consumer binding post unit fault
Typical low pressure fault handling training platform passes through consumer binding post unit loosened screw, simulated field consumer inlet wire fault, first visual examination.It is normal that consumer connection terminal line voltage measured by application multimeter, consumer inlet wire side voltage is 0V, can be judged as that consumer connection terminal outgoing line side is to consumer inlet wire side fault, disconnect consumer, disconnect binding post unit gauge tap, check that after changing fault wire, power transmission is normal.Measure consumer connection terminal primary voltage with multimeter normal, outgoing line side voltage is 0V, can be judged as consumer connection terminal fault, disconnects binding post unit gauge tap, and check and change connection terminal, power transmission is normal.
