Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
A kind of relay protection and automatic safety device remote operation functional test platform; as shown in Figure 1; comprise distant place testing and control main frame and relay-protection tester; described distant place testing and control main frame is connected with relay protection to be measured and automatic safety device by the network port; described distant place testing and control main frame is connected with relay-protection tester by USB interface, and described relay-protection tester is connected with relay protection to be measured and automatic safety device by current interface.
Described distant place testing and control main frame is integrated with the simulation of remote operation function message and relay-protection tester controlling functions; realize remote operation analog message to send, control relay-protection tester simulated failure electric current output function, and can judge the result of the action of relay protection to be measured and automatic safety device.Analog quantity and output switch parameter is produced in relay protection to be measured and automatic safety device under the control of described relay testing instrument testing and control main frame in the distance.In the present embodiment; distant place testing and control main frame is a PC; network interface card and USB interface is provided with in this PC; support ICP/IP protocol; PC is connected with test system by network interface card and RJ45 port twisted-pair feeder; this PC is connected with relay-protection tester by USB interface and USB line, and relay-protection tester is connected with test system by cable (current line).In the present embodiment, relay-protection tester adopts the star equipment of rich electric 662 relay-protection testers or relay protection.
Principle of work of the present utility model is:
Distant place testing and control main frame reads the IEC61850-model of relay protection to be measured and automatic safety device, and fetch protection function quantity, soft pressing plate quantity, output clamping quantity, according to testing standard database, work out testing scheme automatically.Corresponding defencive function carries out the test of distant place amendment definite value, does switching experiment for soft pressing plate, output clamping, and by relay-protection tester simulated failure amount, checking protection pressing plate is thrown and moved back correctness.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
