Product Description
Portable VCB Test Vacuum Degree Tester of Circuit Breaker Vacuum Interrupter Tester with High-speed Printer
Unique Selling Points
Non-Disassembly Design: Innovative excitation coil installation method allows side mounting around the arc chamber, avoiding the need for disassembly and reinstallation. This reduces professional workload and prevents damage to the arc chamber during disassembly.
Early Fault Detection: Unlike traditional frequency withstand voltage methods that only detect severe degradation, this tester can identify vacuum degradation at the early stage (10⁻⊃2;~10⁻⊃1; Pa), enabling timely maintenance and replacement, and reducing maintenance costs.
High Adaptability: Compatible with vacuum tubes of different diameters (classified into four types via DIP switch), suitable for various models of vacuum switches. It operates normally in a temperature range of -20℃~40℃, adapting to harsh on-site environments such as high and low temperatures.
Dual Testing Procedures: Leak detection first excludes severely leaky vacuum tubes, avoiding unnecessary quantitative testing. Quantitative measurement provides accurate vacuum values, ensuring test result reliability.
Intelligent Automation: The single-chip microcomputer automatically controls the testing process—charging, voltage application, data analysis, and discharge. Operators only need to follow simple steps, reducing the learning curve.
Safe & Reliable: Equipped with multiple safety protection measures, including protective grounding, automatic discharge after testing, and high-voltage isolation. Clear wiring instructions prevent misconnection, ensuring operator and equipment safety.
Practical Data Management: Built-in printer supports on-site report printing for immediate documentation. Test results are displayed in scientific notation, which is intuitive and easy to record. It can also calculate the allowable storage time of the arc chamber based on test data.
