KDYZ-301 Arrester resistance current tester

Descriere

Arrester resistance current tester

It is a special instrument for testing the electrical performance of zinc oxide arrester on site or in laboratory, such as power station and substation, which is suitable for the detection of electrification or power outage of zinc oxide arrester of various voltage levels.

Funcționare simplă, ușor de folosit, the measurement process is controlled by the industrial computer, can measure the current of zinc oxide arrester, resistance current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference, large screen can display the real waveform of voltage and current.

The instrument uses digital waveform analysis technology and software anti-interference methods such as harmonic analysis and digital filtering to make the measurement results accurate and stable, and can accurately analyze the content of fundamental wave and 3 ~ 7 harmonics, and can overcome the influence of interphase interference, and correctly measure the resistance current of edge phase arrester.

Product characteristics
1.800 ×480 color LCD touch screen, high-speed thermal printer; Graphic display, Ușor de operat și utilizat personal la fața locului.
2. Wireless transmission of PT signals over 400 metri, on-demand configuration can reach 2000 metri, can meet the needs of various experimental sites.
3. Suitable for lightning arrester live, pană de curent sau laborator și alte locuri de utilizat.
4. A variety of voltage reference signal sampling methods: not only to meet the 6-35kV zinc oxide arrester field live test can also be used for 35-750KV live operation, with induction board, Bluetooth function.
5. Wired synchronization: the signal is taken from the PT end metering winding, and the digital signal is transmitted wired.
6. Wireless synchronization: the signal is taken from the PT end metering winding, and the digital signal is transmitted wirelessly, eliminating the long distance connection of the cable.
7. Induction board synchronization: do not need to take signals from the PT terminal, install induction board from the zinc oxide arrester B phase base to take voltage signals.
8. No voltage synchronization: It does not need to obtain signals from the PT terminal, and uses software calculation to find the voltage reference.
9. Voltage and current signals (input impedance less than 1Ω) are isolated to ensure data reliability and security.
10. It has three channel resistive current measurement at the same time and provides two anti-interference modes at the same time.
① No interference: In this mode, the instrument will not automatically correct the interphase interference Angle when measuring;
2 Interference: In this mode, the instrument measurement will automatically calculate and correct the interference Angle between phases, and the measurement of ABC three-phase can be completed at the same time with only one connection.
11. Real three-phase current, three-phase voltage test at the same time, automatic calculation without compensation, improve work efficiency; There is only weak current inside the instrument, and the voltage does not exceed 12V; Current and voltage sensors are isolated, safe and reliable.
12. Support wired synchronization, wireless synchronization two voltage reference signal sampling methods; It also supports the non-voltage mode. The voltage reference can be found through software calculation, and the three-phase or B-phase voltage reference can be used as the voltage reference.
13. Ac, DC dual-purpose type; Internal lithium-ion battery, especially suitable for no power occasions, a charge can work for dozens of hours.
14. Equipped with Widows operating system, support direct shutdown mode; Equipped with a USB interface, support U disk to export data; It can be used with external USB mouse and keyboard, usor de operat.
15. The internal SD card with 4GB capacity can store massive test data, and has functions such as data management and storage.
16. Supporting upper-layer management software, with historical data management, data analysis, survival word report printing and other functions, built-in help documents, attached wiring mode pattern, strong light line can adjust the background picture and color, support interface screenshots saved as BMP pictures.
17. High-speed sampling frequency, digital signal processing technology, with arrester resistance current test, monitor current calibration and monitor action test and other test functions, high test accuracy.
18. Dustproof, impermeabil, cutie sigilată din plastic de inginerie anticorozivă, mărime mică, greutate redusă, usor de purtat.
