Description of drawings
Fig. 1 automobile fusible line operating chacteristics test unit structure principle chart.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring at Fig. 1, this test unit comprises power switch 1, accumulator 2, pilot lamp 3, the time relay 4, relay for automobile 5 and 7 sum counters 6.Relay 7 solenoids one end is electrically connected with battery positive voltage by power switch, and the relay 7 solenoid other ends are electrically connected with battery terminal negative; The normally opened contact of the time relay 4 solenoids one end, the time relay 4 and normally closed contact one end are electrically connected with relay 7 normally opened contacts one end by pilot lamp 3, and the time relay 4 solenoid other ends are electrically connected with battery terminal negative; The time relay 4 normally opened contact other ends are electrically connected with relay 5 solenoids one end, and the relay 5 solenoid other ends are electrically connected with battery terminal negative; The two ends of relay 5 normally opened contacts are electrically connected with two counting ends of counter 6.
The time relay that is adopted is a cycle time relay, a pair of normally opened contact and a pair of normally closed contact are arranged, as be S1 and S2 the cycling time that the time relay is set, when giving the solenoid energising of the time relay, elder generation's normally opened contact disconnects the closed S1 of S1(normally closed contact), be recycled to the closed S2(normally closed contact of normally opened contact then and disconnect S2).
According to QC/T 220-1996 " automobile fusible line " testing requirements, in fusible line being carried out the operating chacteristics test, be not less than with precision
+0.1S stopwatch, the time of fusible line when beginning to be energized to fusible line fusing is carried out timing.The utility model is being set to 0.1S and 0.1S the cycling time of the time relay 4.
Before carrying out fusible line operating chacteristics test, by the requirement of Fig. 1 one end of the fusible line 8 that will test is electrically connected with battery positive voltage, the other end of fusible line 8 is electrically connected with relay 7 normally opened contacts one end.During test, press power switch 1 energized, the test of beginning fusible line operating chacteristics.
Its principle of work is as follows:
When pressing power switch 1
(1) electric current is by accumulator 2 positive poles → by power switch 1 → make relay 7 solenoid energising → relays 7 normally opened contact closures to accumulator 2 negative poles by relay 7 solenoids;
(2 electric currents make fusible line 8 energisings by the solenoid of accumulator 2 positive poles → by fusible line 8 → by relay 7 normally opened contacts → by pilot lamp 3 → by the time relay 4 to accumulator 2 negative poles;
(3) normally opened contact of the solenoid energising → time relay 4 of the time relay 4 disconnection 1S → relay 5 solenoids are not switched on;
(4) the solenoid energising → time relay 4 of the time relay 4 is recycled to closed 1S → counter 6 countings of the closed 1S → relay 5 solenoids energising of normally opened contact 1S → relay 5 normally opened contacts once;
When relay 7 closures make fusible line 8 energising, the time relay 4 constantly circulation makes the continuous power on/off of relay 5 solenoids, and relay 5 normally opened contacts are constantly closed to be disconnected, the every closure of relay 5 normally opened contacts once, rolling counters forward is once.Pilot lamp 3 bright expression fusible line 8 energisings, during fusible line 8 energisings, the continuous stored count of counter.When fusible line 8 fusing, pilot lamp extinguishes, time relay outage, and counter stops counting.Power cutoff switch 1 stops test at this moment.
Time when fusible line fuses from beginning to be energized to fusible line is:
0.1 second * counter cumulative number.
