Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, for four sections of the present utility model export loop test system, comprise power supply 1, power module 2, timing relay 1 and timing relay 24 that voltage supplied is 220V, power module 2, timing relay 1 are all connected with power supply 1 with timing relay 24, and the 220V voltage transitions that power supply 1 supplies by power module 2 becomes the direct current of 1.5V.

The normally closed contact of timing relay 1 is connected with auxiliary reclay 1, timing relay 1 by normally closed state signal transmission to auxiliary reclay 1; The normally opened contact of timing relay 1 is connected with auxiliary reclay 26, timing relay 1 by normal ON state signal transmission to auxiliary reclay 26; Auxiliary reclay 1 and auxiliary reclay 26 respectively by its own signal back transfer to timing relay 1.The normally closed contact of timing relay 24 is connected with auxiliary reclay 37, timing relay 24 by normally closed state signal transmission to auxiliary reclay 37; The normally opened contact of timing relay 24 is connected with auxiliary reclay 48, timing relay 24 by normal ON state signal transmission to auxiliary reclay 8; Auxiliary reclay 37 by its own signal back transfer to timing relay 24.All be communicated with between auxiliary reclay 1 with auxiliary reclay 37, between auxiliary reclay 26 with auxiliary reclay 48, its own signal can be directly passed to timing relay 24 by auxiliary reclay 1.The start-up time of auxiliary reclay 1, auxiliary reclay 26, auxiliary reclay 37 and auxiliary reclay 48 staggers mutually.

The positive pole of power module 2 connects auxiliary reclay 26, and auxiliary reclay 26 is connected with assembly 9 to be tested, and power module 2 applies positive electricity to assembly 9 to be tested by auxiliary reclay 26.The negative pole of power module 2 connects auxiliary reclay 48, and auxiliary reclay 48 is connected with assembly 9 to be tested, and power module 2 applies negative electricity to assembly 9 to be tested by auxiliary reclay 48.The start-up time of auxiliary reclay 26 and auxiliary reclay 48 staggers mutually, avoids forward 1.5V voltage and reverse 1.5V voltage to be applied to short circuit assembly 9 to be tested causing assembly 9 to be tested simultaneously.

The output circuit of auxiliary reclay 48 is connected with counter 10, when described four sections of output loop test systems complete a complete cycle, counter 10 counts once.

When four sections of output loop test system energization of the present utility model use, timing relay 1 is first started working and timing, and the auxiliary reclay 1 that its normally closed state controls exports the first via signal of described loop test system; After timing relay 1 timing T1 arrives, produce release movement, self timing pause TP, first via signal exports and disconnects, now timing relay 24 is started working and timing, and the auxiliary reclay 37 that its normally closed state controls exports the second road signal of described four sections of output loop test systems; After timing relay 24 timing T1 arrives, produce release movement, self timing pause TP, second road signal exports and disconnects, now timing relay 1 recovers timing, and produces release movement, and the auxiliary reclay 26 that its normal ON state controls exports the 3rd road signal of described loop test system; After timing relay 1 timing T2 arrives, produce release movement, self timing pause TP, 3rd road signal exports and disconnects, now timing relay 24 recovers timing, the auxiliary reclay 48 that its normal ON state controls exports the 4th road signal of described loop test system, and counting pulse signal is passed to counter 10 by auxiliary reclay 48; After timing relay 24 timing T2 arrives, produce release movement, self timing pause TP, the 4th road signal exports and disconnects, and timing relay 1 is started working again, enters next circulation.
