ZXAS-1000A: Precision & Power for Modern DC Breaker Testing

Time:2025-07-09 Number:1

Introduction:
Testing DC circuit breakers demands robust, precise equipment capable of handling high currents while delivering accurate performance data. The ZXAS-1000A DC Circuit Breaker Tester rises to this challenge, offering a significant leap in capability and convenience compared to older generation testers. Designed for rigorous field and lab use, it addresses the core needs of technicians and engineers working with DC protection systems up to 1000A.

Key Features & Advantages Over Conventional Testers:

High Current, High Precision: Leveraging power electronics control, the ZXAS-1000A generates currents from 1A to 1000A with exceptional stability (≤0.5% variation) and low ripple (<5%). This surpasses older resistive load banks or less sophisticated electronic testers, which often struggle with stability at lower currents or exhibit higher ripple, potentially skewing trip time measurements.

Intelligent Auto-Ranging & High-Resolution Acquisition: Multiple high-precision sensors enable seamless automatic current range switching. Coupled with a 14-bit AD acquisition chip, the instrument achieves remarkable measurement accuracy across its entire 0-1000A span. This eliminates the manual range switching and potential errors associated with simpler testers using fewer or lower-resolution sensors.

Comprehensive Testing Modes: It offers both Ampere-Second (I-t) Characteristic Testing (critical for verifying time-delay curves) and Through Current Characteristic Testing. This dual capability provides a more complete breaker assessment than testers limited to only one mode.

Enhanced Data Management & Connectivity:

Onboard: Features a 320x240 LCD, thermal printer, and keyboard for standalone operation. It automatically stores up to 200 test results, retaining data through power loss – a major advantage over testers with volatile memory or limited storage.

PC Connected: Offers full remote control, data import/export, report generation, and graphing via PC software. This level of integration facilitates detailed analysis, reporting, and long-term trend tracking far beyond basic testers lacking PC interfaces.

Robust Protection & Reliability: Incorporates comprehensive safeguards against overheat, over-current, and over-voltage conditions. Its strong Electromagnetic Compatibility (EMC) ensures reliable operation in electrically noisy substation or industrial environments, where less robust testers might malfunction.

User-Centric Design: The interactive OS and clear display streamline operation. The thermal printer provides immediate hard copies onsite – a practical feature often missing in lower-end or purely PC-dependent units.

Technical Superiority in Key Metrics:

Output Stability (≤0.5%) & Ripple (<5%): Ensures the applied current is clean and consistent, leading to more reliable trip time recordings compared to testers with poorer regulation.

Wide Operating Temperature (-20°C to 50°C): Suited for harsh environments, outperforming testers with narrower operating ranges.

High Timing Resolution (0.001s): Crucial for accurately capturing fast breaker operation times.
