The invention is characterized in that the technological improvement of intelligent relay protection test platform, is controlled using PLC intelligent computers, it is one-touch to press
The triggering of button program can accurately measure action and return voltage and the contact-actuation time of 10 same type relays simultaneously, together
When data message information can be provided to coil resistance, contact action resistance value.It is not only saved the duration, is improved existing using the platform
Field working efficiency increases verification precision, has simplified operating procedure significantly.
Using the relay interface pedestal of customization, it can access and survey without wiring directly by relay inserted base
Test system；The relay access circuit board that customization is installed on relay base, is used for each relay coil and contact is whole
Test circuit is introduced, so that test process is by logic control, coil, each contact is connected by switching component and extremely tested back
Road is not necessarily to artificial wiring.The circuit that is formed by relay normally closed contact of relay access circuit board of test platform, detect after
Whether electric appliance is inserted in place, and starting test for embedded system provides Rule of judgment.Using relay base and access board hardware electricity
Lu Hou can substantially reduce artificial wiring workload, thoroughly solve the failure risk caused by wiring error.Relay base and
Access board is connect by connecting line with power-supply system and embedded microprocessor system, very convenient can be replaced, for not
With relay, only need to change pedestal and access circuit board group at panel, you can meet testing requirement, it is entire without needing to change
Test platform.
Automatically testing platform, as lower computer hardware, test electricity is controlled by embedded software using embedded microprocessor
Source and testing process and test logic.Each relay writes a test logic flow, passes through plug in software module reality
Existing, platform is applicable to almost all of intermediate relay and the time relay and part protective relay.Hardware and software
Cooperation, the working value of relay, return value, actuation time, time of return, contact impedance etc. can be tested automatically.It is embedding
Enter microsever to start test automatically, automatically control test process and logic, automatic collection test result data, and in real time on
Pass to host computer.So that host computer can obtain test process data and test mode and fault message in real time.Whole process is only
Relay to be measured need to manually be replaced, click start button, be not necessarily to manual intervention, until test is completed.Greatly reduce survey
The complexity of examination improves testing efficiency, and embedded microprocessor system executes the time of operation in delicate or even nano-seconds,
Read test data precision is significantly larger than artificial, can greatly reduce the people of test data because of error.
Host computer, as hardware, is write dedicated program, is communicated with slave computer using laptop.It is tested in real time
Progress, state and test data, also receive manual intervention, start, pause, terminate test process.Finally according to test data,
Automatically form testing journal sheet.
