Description

Technical Field

[0001] The utility model belongs to the field of electrical hardware detection, and in particular relates to a single complete machine hardware testing platform for a feeder terminal FTU. Background Art

[0002] With the development of power system automation technology, the demand for intelligent equipment has increased. As a complete set of primary and secondary integrated pole-mounted switch control equipment, the feeder terminal FTU can collect real-time line operating condition information, such as electrical quantities such as voltage and current, switch position, energy storage status and other input quantities, and monitor the line operation status through built-in logic, conduct fault analysis, and complete logical judgment on the spot to isolate or remove the fault. At the same time, the operating conditions and fault information obtained by the terminal can be sent to the main station system through communication, so that the main station system can timely understand the current line operation status. The terminal can also obtain control commands issued by the master station through communication and execute them.

[0003] FTU has many functions: three remote functions, output control function, power management function, communication function, wave recording function, distribution line line loss measurement function, time synchronization / positioning function, historical data storage function, self-test function, three-stage overcurrent protection, two-stage zero-sequence overcurrent protection, excitation inrush current detection function, overload protection function, current blocking, PT disconnection detection function, reclosing, synchronization check function, fault indicator automatic reset function, small current grounding fault discrimination function, post-acceleration protection function, local feeder automation function, etc. These functions are closely related to the hardware, electrical wiring and normal operation of the FTU device.

[0004] FTU is composed of numerous chips, modules, electronic components, and electrical wiring. Usually, after the feeder terminal FTU manufacturer wins the bid, the production process is to send the electronic components to the PCB welding manufacturer for welding. After welding, the finished PCB board is returned to the FTU manufacturer for assembly and electrical connection to finally obtain the finished FTU. Since the whole machine contains a large number of modules and devices, manual inspection will cause a lot of workload, waste company resources, greatly increase the company's costs, and cannot guarantee the comprehensiveness, correctness, and consistency of the test.

[0005] In view of the above problems, the present invention proposes the following technical solutions.

[0006] A single-unit hardware test platform for feeder terminal FTU, including a computer, a network switch, a relay protection tester, a network port, a serial port, and an aviation plug;

[0007] The aerial plug is connected to the relay protection tester, and the other end of the aerial plug is used to connect to the feeder terminal to complete the electrical connection between the relay protection tester and the feeder terminal;

[0008] The relay protection tester is connected to the computer through a network switch, and is used to receive instructions from the computer and send test data to the computer;

[0009] The network port is connected to the computer through a network switch, and the other end of the network port is used to connect to the feeder terminal to complete the computer's network port detection of the feeder terminal;

[0010] The serial port is connected to the computer, and the other end of the serial port is used to connect to the feeder terminal to complete the computer's serial port detection of the feeder terminal.
