Description
Technical field
The present invention relates to fuse testing field, especially a kind of all-electronin fuse test of more set fuse concurrent testings
Instrument.
Background technology
All-electronin fuse tester is used exclusively for detecting the important tool of the functional reliability of all-electronin fuse.It is general complete
Electronic fuse tester has the functions such as self-test, calibrating, fuse status monitoring.Detection to fuse is mainly drawn by all-electronin
The control signals such as tester simulation power supply, Xie Bao, triggering, reset are believed to monitor the working condition of fuse, and are entered by indicator lamp
Row display.
2013,《Detection and control journal》The phase the 35th of periodical the 3rd curly hair table《It can be compiled on fuse electronic safety system piece
Journey tester versatility technology》In one text, describing in detail can compile on a kind of SCM Based fuse electronic safety system piece
Journey tester.Wherein, mentioned in 2.3 sections " low cost, high reliability, high environment adaptability design "：" devise one general to draw
Letter detection interface, combine control signal, the test signal of various fuse types（Containing analog quantity and digital quantity）, test cable know
Other point（Four points）, power supply and ground etc. "；Wherein 3.1 sections " PTT fuse is quickly identified, tested automatically " are mentioned：" pass through panel
The red green state of upper ' fuse solution protects state ' lamp measures and shows that fuse solution protects state in real time；Pass through ' fuse detection knot on panel
Fruit ' the red green state of lamp measures and shows fuse eligible state in real time.When one carry out the coffin upon burial letter test complete, another letter of carrying out the coffin upon burial of changing-over,
Repeat singly-bound and start detection.”
It can be seen that all-electronin fuse tester only has a detection interface at present, can only be all fuses when testing multiple fuses
Sequential testing：Survey one to carry out the coffin upon burial letter, waited a few minutes to remove it from detection cable plug, the next letter of carrying out the coffin upon burial of changing-over repeats to grasp
Make.
If all-electronin fuse tester only has a detection interface, then when required test fuse is a fairly large number of
Wait, fuse can only be tested one by one, repeated.It is so both cumbersome, lose time again, this be present in prior art not
Foot part.
