Project Description
Product Features:
Integrated structure, small size and light weight
The instrument is highly integrated. It integrates nearly one truck of equipment in the traditional measurement method in the integrated main box; it is the smallest and lightest among the domestic equivalent products; it provides the simplest and most convenient test method. Test method.
Easy access to power supply
All the measurement processes of the instrument only need to be connected to the 220V mains voltage, which solves the inconvenient connection of the 380V voltage on site in the existing measurement methods.
The line parameter tester is an integrated structure with a built-in variable frequency power module, which can output power with variable frequency and voltage regulation. The frequency can be changed to 45Hz or 55Hz, and digital filtering technology is adopted to avoid the interference of power frequency electric field on the test, and fundamentally solve the problem of accurate measurement under strong electric field interference. At the same time, it is suitable for the occasions where the generator is used for power supply detection after all power failures.It belongs to cable line tester.
With the development of power grids and the shortage of land for line corridors, the situation of multi-circuit erection on the same pole is becoming more and more common, the coupling between transmission lines is getting closer, and the interference is getting stronger and more serious during the power frequency parameter test of transmission lines. Affects the accuracy of the test and the safety of the test equipment.
In response to this problem, we have developed a new generation of transmission line inter-frequency parameter test system, integrated variable frequency test power supply, precision measurement module, DSP high-speed digital processing chip and unique national Patented technology anti-inductive voltage circuit; effectively eliminate the influence of strong interference, ensure the safety of equipment and equipment, and can measure the power frequency parameters of power transmission lines extremely conveniently, quickly and accurately.
