Apparatus structure is simple, fault detector that is easy to operate, being applicable all producers.
Effectively validation fault indicator whether there can be wrong report, fail to report, make a false report phenomenon.
Device volume is small, lightweight, conveniently moving, is adapted to field test.
Brief description of the drawings
Fig. 1, is a kind of electric theory diagram of portable thread line fault indicator tester of the invention.
Fig. 2, is the workflow of measurement circuit fault detector of the present invention.
Specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described
As shown in figure 1, a kind of portable thread line fault indicator tester, it is characterised in that：Including battery monitor（1）, lithium battery group（2）, inverter（3）, controller（4）, guidance panel（5）, primary coil（6）, alloy core（7）, secondary coil（8）, load resistance（9）, controllable short switch（10）, terminal 1（11）, copper bar（12）, terminal 2（13）；Battery monitor（1）With lithium battery group（2）Connect, lithium battery group（2）With inverter（3）Input connects；Inverter（3）Output end and controller（4）Input connects；Controller（4）Output and controllable short switch（10）Connect；Controller（4）With guidance panel（5）Connect；Controller（4）Output end and primary coil（6）Connect, secondary coil（8）One end exports and load resistance（9）, controllable short switch（10）Phase simultaneously connects, secondary coil（8）The other end in terminal 1（11）Connect, load resistance（9）With controllable short switch（10）The other end and terminal 2（13）Phase simultaneously connects, primary coil（6）And secondary coil（8）All it is wound on alloy core（7）On, alloy core（7）It is shaped as O-shaped；Controller（4）Control primary coil（6）Input different electrical power voltage, secondary coil（8）Primary coil can just be sensed（6）The induced-current of different voltages；Terminal 1（11）With terminal 2（13）Use copper bar（12）Connection short circuit, will produce different electric currents, can control short switch（10）By guidance panel（5）Control, be equivalent to line short during closure, produce short-circuit power supply；Tested fault detector clips to copper bar（12）On, secondary coil（8）The short circuit current of generation and through load resistance（9）Load current all can be by copper bar（12）Part is produced；During short circuit current, controller（4）Primary coil is just disconnected at once（6）Electric current, secondary coil（8）Just produced without electric current, had a power failure after short circuit equivalent to transmission line of electricity；Thus with simulation short trouble after have a power failure come measurement circuit fault detector whether failure, a kind of portable thread line fault indicator tester is arranged in same Portable machine box, it is about 15Kg as convenient test equipment its weight, solve the problems, such as that line-failure indicator detection hardly possible, detection will arrive given place, make the detection of line-failure indicator more convenient, simple, fast.
