KDZD Pressure Relief Valve Test Bench | Transformer Safety Calibration System

Applications:

The KDZD Pressure Relief Valve Test Bench is specifically engineered for the maintenance and quality assurance of oil-immersed transformers and power equipment. Its primary application is to ensure the operational reliability of pressure relief valves, which are critical safety components in electrical substations and power plants. This system is widely used by power grid maintenance teams, transformer manufacturing facilities, and third-party calibration laboratories to prevent catastrophic failures, oil leakage, and forced outages by verifying the valve's response to internal fault pressures.

Profile:

The KDZD Pressure Relief Valve Test Bench is a sophisticated calibration system designed to safeguard the integrity of oil-immersed transformer tanks. By simulating the pressure dynamics of internal transformer faults using air as the test medium, this device accurately verifies the critical "open" and "close" performance of pressure relief valves.
Engineered to prevent transformer damage or major accidents caused by valve failure, the system automates the entire inspection process. From a single clamping operation, it conducts comprehensive tests including aging opening pressure, opening pressure, closing pressure, sealing performance, and signal contact detection. This ensures that the valve operates reliably to prevent tank rupture during overpressure events and seals securely to avoid oil leakage during normal operation.

Features:

  • Full Automation: One-time clamping initiates an automatic sequence to complete aging opening, opening pressure, closing pressure, sealing performance, and signal contact testing without manual intervention.
  • Advanced Safety System: Equipped with a triple protection mechanism including overpressure protection (to prevent equipment damage), delay protection (to prevent personnel injury), and overpressure inhibit-start protection (to prevent accidents caused by misoperation).
  • High-Precision Data Acquisition: Utilizes dynamic automatic real-time pressure collection to reflect true opening and closing values, eliminating the need for electrical contact points.
  • Intelligent Software Interface: Features a 19-inch true-color LCD display with software that synchronously plots pressure-time curves for visual analysis.
  • Third-Party Calibration Ready: Includes an independent quantity transfer and correction interface, allowing for on-site whole-machine calibration by third parties without disassembly.
  • Customizable Sealing Test: Allows users to set pressure and sealing time parameters for fully automated sealing verification.
  • Extended Storage: Capable of storing an unlimited number of calibration datasets for traceability and analysis.
