DC Air Circuit Breaker Characteristic Tester

DC Air Circuit Breaker Characteristic Tester

MOEORW-WKA15: A portable, automated professional testing equipment for DC air circuit breakers, specifically designed for substation sites.

High-precision touch operation, multi-mode testing, data storage and export, and comprehensive security protection.

On-site verification and operation and maintenance testing of ampere-second characteristics and differential coordination of DC circuit breakers in substations

Based on the current situation of DC protection device ampere-second characteristic testing, our company has launched the MOEORW- W KA15 DC air circuit breaker characteristic tester, which is suitable for use in substations, portable, and highly automated. It can provide operation and maintenance departments with a means to test the operating characteristics of DC protection devices, verify the operating characteristics and differential coordination of DC protection devices, so as to improve the reliability of DC system operation and ensure the safe and reliable operation of the power grid.

3) The equipment has a built-in DC current source and adopts switching constant current control technology. It can independently set the constant current output, with fast response speed, high accuracy, strong load capacity, and can work stably for a long time.

4) It has overheat, overcurrent, and overvoltage protection functions, good electromagnetic compatibility, and strong anti-interference ability, ensuring a safer and more reliable testing process;

5) It has a power-off storage function, which can store 1000 sets of test data; it automatically saves parameter settings and does not lose them when power is off;

6) The report conversion software can manage the ampere-second characteristic curves, data, query, analysis and report output of DC circuit breakers, which improves testing efficiency.

7) Suitable for use in substations, featuring an integrated design that is easy to carry and highly automated;

8) Meets the overload and short-circuit characteristic tests and differential tests of DC circuit breakers;

9) The measurement methods include single-point testing, full-point testing, and full-point testing, covering the ampere-second characteristic test, current-carrying non-operating characteristic test, tripping test, circuit level coordination test, and internal resistance test of DC circuit breakers, which fully meets the requirements for characteristic testing of DC circuit breakers;

10) Automatically generate circuit breaker protection characteristic curves (ampere-second curves) and generate report outputs.

11) On-site data can be output as a report via Bluetooth printer.
