Streamlined Precision: The ZX-RLC01 Gas Relay Calibrator Revolution
For Technicians: Calibrating Buchholz (gas) relays is critical for transformer protection, demanding accuracy, efficiency, and reliability. The ZX-RLC01 Gas Relay Calibrator represents a significant leap forward, contrasting sharply with older, often cumbersome calibration systems. Here’s a technical breakdown of its advancements:
Core Innovation: Integrated Design & Single-Pipe Structure
Contrast: Traditional calibrators frequently employ complex multi-pipe (e.g., three-pipe) setups for different flow rates/calibers, resulting in large footprints, higher costs, intricate plumbing, and increased potential leak points.
ZX-RLC01: It utilizes a revolutionary single-pipe structure with integrated 25mm and 50mm tapered sections within an 80mm main pipe. This drastically reduces physical volume, cost, and system complexity while maintaining the ability to handle all standard relay calibers (25mm, 50mm, 80mm).
Human-Machine Interface (HMI): Embedded full-color capacitive touch display with wireless keyboard/mouse provides an intuitive interface for controlling flow, volume, seal tests, data visualization, real-time report editing, printing, and secure data storage/retrieval – a stark improvement over basic controls and manual record-keeping.
Advanced Subsystems & Performance:
Data Acquisition (CAN Bus Architecture):
Implements CAN bus for robust, high-speed communication between upper and lower computers.
Enhances data acquisition response time and system longevity.
Simultaneously samples and displays status for three pairs of heavy gas flow rate and light gas volume nodes per test cycle, boosting throughput.
Flow Rate Control & Measurement (Vector Drive & Precision Sensing):
Vector Frequency Converter: Controls a centrifugal oil pump, minimizing output pulsation significantly. This improves flow stability critical for accurate relay tripping simulation.
High-Speed Frequency Measurement: Uses dedicated pulse-output flowmeters (25mm and 50mm). The 25mm meter handles 25mm relays; the 50mm meter handles both 50mm and 80mm relays via calculated flow rate (V = Qv / S). Flowmeters boast 0.5% accuracy, contributing to an overall flow velocity accuracy of 1.5%.
Ranges: φ25: 0.6-4.2 m/s; φ50: 0.6-3.2 m/s; φ80: 0.6-2.2 m/s (display resolution: 0.00 m/s).
Light Gas Volume Measurement (Precision Pump Control):
Employs a gear metering pump with motor speed controlled via analog output.
Accurate pulse counting delivers high volume detection accuracy (1.0%) and a wide range (0-950 mL, resolution: 0.0 mL).
Pressure Application & Seal Testing:
Centrifugal oil pump provides test pressure via blocked rotation.
Pressure measured by transducers with 0.5% accuracy (0-250 kPa range, resolution: 0.0 kPa).
Configurable test duration (1-60 min).
Clamping Mechanism (Hydraulic Automation):
Unilateral suspension centering hydraulic clamp ensures relay concentricity (±3mm deviation).
Contrast: Drastically reduces manual effort and alignment time compared to manual or less sophisticated clamping systems.
QJ-40 Compatibility:
Dedicated detection capability (1-150 mm range) with 1.0% accuracy and 0.0 mm resolution.

The ZX-RLC01 Gas Relay Calibrator sets a new benchmark by integrating advanced engineering – the single-pipe design, CAN bus architecture, vector drive control, precision pulse measurement, and automated hydraulic clamping – into a user-friendly platform. It directly addresses the limitations of older calibrators: reducing size, cost, and complexity while significantly enhancing measurement accuracy, stability, test speed (3-node simultaneous testing), operator ergonomics, and data management capabilities. For technicians focused on precision, efficiency, and reliable transformer protection system validation, the ZX-RLC01 represents a substantial technological and operational advancement.
