Q1: What is a relay tester?
A1: Relay tester is an important test tool to ensure the safe and reliable operation of power system. With the continuous expansion of the scale of modern power systems and the continuous improvement of the reliability and efficiency requirements of power system operation and management, the testing work of relay protection personnel has become more frequent and complex. The relay protection tester uses a high-performance industrial computer as the control computer, and directly runs the Windows operating system. The back panel of the device is provided with USB ports, network ports, serial communication ports, etc., which can facilitate data access, data communication and software upgrades.
Q2: What are the functions of protection relay tester?
A2: Protection relay tester needs to be able to respond to the faults and abnormal actions of electrical equipment, and can automatically, quickly and selectively act on the circuit breaker, remove the faulty device from the system, and ensure that the faulty device continues to work. And limit the incident to a minimum, improve the reliability of the system operation, and maximize the safety of the user's connection to the power supply. The role of relay test equipment is the role of automation equipment. "Normal" and "abnormal" operating conditions must be in the correct zone, as well as "external faults" and "internal faults" of the components to be maintained to complete the relay. Electrical maintenance function. Therefore, changes in various physical quantities reflected under various conditions can be detected and identified.
Q3: What are the advantages of relay tester?
A3: The relay protection tester has various forms in the output of current intensity, which can meet the characteristics of actual field experiments. Relay test set is not only compatible with each traditional experimental method, but also can easily carry out three-phase transformer differential protection experiments and factory power fast switching and standby self-switching experiments. Its powerful software functions can realize a variety of high-level automation technology, and large and medium-sized complex verification work. It also has the characteristics of its high-performance host and flexible output of current intensity, which greatly improves the detection production efficiency. Not only its real-time data digital signal processing ability is strong, and the operation speed is faster, but also the output waveform of the instrument equipment has high precision, small frame loss and good linearity. The function of the relay protection tester is to check whether the operation of the comprehensive relay can work normally, in order to verify the technicians find the problem early, and then deal with it in a timely manner to protect the normal operation of the overall power system.
Tips: The main circuit of the relay protection tester working principle
The input AC220V power supply enters the input end of the double carbon brush voltage regulator T1 through the output control relay K1 through the insurance, and the power adjusted by the large knob of T1 enters the isolation transformer T2 (part-time booster). The booster is divided into three taps for output, one The tap is AC0-250V output, and the rated current is 3A; the output voltage of this tap can output 0-350V DC voltage after rectification and filtering; the second tap is 15V (10A), and the tap is controlled by the sensor through the relay to output 0-10A AC current, one channel outputs 0-500mA AC current through resistance, and one channel outputs 0-10A or 0-500mA DC current through relay conversion; the second tap is 10V (100A) high current end, which passes through the primary side of the sensor directly. The output current is 100A. The loop has a strong load capacity, but the output is slightly overloaded and cannot be in a high current state for a long time.
