6 Channels 450V 6A Multifunctional Vector Analyzer For On Site
Introduction
With the development of the power industry and the promotion and application of microcomputer integrated automation products, the correct wiring of the protection loop and the metering loop directly affects the stability of the power system and the accuracy of the electricity metering, and these two points are two very important aspects of the power system. Due to the more wiring of the protection device and the high voltage metering device, it is easy to cause wrong wiring, and it is not easy to be detected, (especially the complex wiring of differential protection, sometimes the high and low sides are introduced at the same time, the transformer connection has a variety of forms, and there are different connection groups, and the high and low voltage side CT also has a variety of different combinations, which is easy to connect wrong. In normal operation, it may not achieve the conditions of misoperation and is not easy to be found, there is a great hidden danger). According to the needs of field testing, Guodian Zhongxing timely developed ZXSL-601 multi-function vector analyzer. It can be used as a phase meter to verify the correctness of the main variable differential protection and the bus differential, and can be used as an electrical parameter tester to test the necessary parameters of the power system, and can also be used as a three-phase three-wire power metering wiring detection instrument, while measuring 2 ~ 32 harmonic content. Adopting DSP AC sampling, it can measure 3 voltage and 6 current analog quantity at the same time, the instrument channel vector is displayed on the same screen, the human-machine dialogue interface is friendly, easy to use, greatly convenient for field use, and it is the right-hand assistant of power workers.
Features
1. Three-channel voltage and six-channel current vectors are displayed on the same screen; for the test of differential protection devices, only one wiring is required to complete the drawing of the hexagonal diagram, which greatly improves the work efficiency; in the case of small space and difficult wiring, it can also Use the double-clamp method to make multiple measurements to draw a complete hexagonal graph.
2. The clamp-type current transformer is used for wiring without disconnecting the current loop, which is safe and convenient.
3. Vector analysis of complex protection devices can be performed to determine whether the wiring is correct, and the correct wiring diagram is given for comparison.
4. It can carry out conventional electrical parameter test, and display three-phase voltage, three-phase current, three-phase active power, three-phase apparent power, three-phase phase angle; and can directly read the voltage amplitude converted to the primary side of the transformer, The value of current amplitude and power.
5. The three-phase three-wire high-voltage measuring device can be checked for wrong wiring, and the 48 types of three-phase three-wire wiring can be analyzed and judged to directly give the analysis results; investigate and deal with the malicious stealing of the metering wiring to effectively avoid the loss of electricity charges.
6. Harmonic analysis of the measured signal on the spot can be carried out, each content of the 2nd to 32th harmonic can be analyzed, and the total harmonic distortion can be calculated automatically.
7. Large-screen, high-brightness color LCD display, full English character graphical menu and operation prompts realize friendly human-machine dialogue. Touching the silicone buttons makes the operation comfortable and feels good. The wide-temperature LCD with brightness adjustment can adapt to winter and summer seasons.
8. Large-capacity lithium battery power supply, continuous work for up to 6 hours.
9. The user can save the test data in the form of record at any time for centralized and unified management, record and inspection, and can store more than 2000 sets of data.
10. The saved records can be uploaded to the background management computer for comprehensive analysis and review.
11. With perpetual calendar and clock function, real-time display the date and time of test work.
12. Small size and light weight, easy to use on site.
13. The USB interface is reserved, and instruments can be used to replace USB flash drives and other mobile storage devices.
