Further, referring to Fig. 5, in order to clearer explanation the utility model, below with of the present utility model
The utility model is further detailed preferred embodiment.The preferred embodiment of the present utility model is to utilize this relay
Protection suit carries out the experiment of DL-32 type electric current relays acting characteristic,
Specifically experiment process is：
1st, computer 1 and computer 2 are opened, the main program of computer 1 and computer 2 is respectively enterd, then in computer 2
Upper selection needs the protective relaying device tested, selects " DL-32 types electric current relay " here, now, display screen 1 and aobvious
Display screen 2 is shown that such purpose is to make the hardware of virtual instrument according to relay protection experimental demand (program is previously set)
Mark is clearer.
2nd, wiring is carried out according to experimental principle, display screen 1 and display screen 2, specifically as shown in figure 5, the data are adopted
8,2,1,3 terminals of the data collecting card 2 that Ia, In, X1, X2 terminal of truck 1 connect respectively, 4 ends of the data collecting card 2
Son 6 terminals of connection, the terminal Y5-1 and Y5- of the data collecting card 5 that the normal opened contact 1 and 2 of the data collecting card 3 connects respectively
2 terminals, terminal Y6-1 and the Y6-4 terminal for the data collecting card 6 that the normal opened contact 1 and 4 of the data collecting card 4 connects respectively.
3rd, after the completion of wiring, " pre-detection " button of computer 1 now in interface is clicked on, due to computer 1 and computer 2
With communication relations, now, computer 2 can be also scheduled for according to prior program.The control of the Program of computer 2 makes data acquisition
Terminal on card 6：Y6-1 and Y6-4 produce electric current, and current values differ, for example electric current is 5mA on Y6-1, on Y6-4
Electric current be 10mA.The normal opened contact 1 and 2 of data collecting card 3 closes, and the normal opened contact 1 and 4 of data collecting card 4 closes.This
When, if experimental implementation person's wiring is correct, 10mA electric current, terminal Y5-2 are received on the terminal Y5-1 of data collecting card 5
On receive 5mA electric current, this data is sent to computer 1 by data collecting card 5.Judgement set in advance in computer 1
Program receives 10mA electric current on the terminal Y5-1 from data collecting card 5,5mA electric current is received on terminal Y5-2, then
Judgement then thinks that wiring is correct, otherwise it is assumed that wiring error.
If the 4, computer 1 judges wiring error, experimental implementation person needs to check wiring, after checking and adjusting wiring
Above step is carried out again until wiring is correct.If computer 1 judges that wiring is correct, experimental implementation person is prompted, can be carried out
In next step.
5th, " starting to test " button after completing " pre-detection " according to computer prompted, is pressed, now, on data collecting card 6
No longer occur electric current, the normal opened contact of data collecting card 3 and data collecting card 4 is again turned on.Data collecting card 1 is by computer 1
Programme-control, plus corresponding electric current, can normally be tested.
By starting to test front progress wiring check, it can protect virtual protective relaying device will not be because of wiring error
Cause to burn out hardware.
In detection above, why only whether detection Ia and In wiring is correct, is because the two binding post positions
Electric current, if wrong line can cause to damage to instrument, even and if passive terminal wrong line, will not also produce damage component cause
Order mistake.Here, it is designed as not detecting, hardware can be saved first, secondly because mode of connection may in relay protection experimental
Not unique, so detection can take hardware and software resource significantly.
The utility model is not limited to above-described embodiment, and embodiment is exemplary, it is intended to for explaining that this practicality is new
Type, and it is not intended that to limitation of the present utility model.
