The Vacuum Switch Vacuum Level Tester is a specialized instrument designed for measuring the vacuum degree within the arc extinguishing chamber of vacuum switches. Based on the DL/T846.9-2004 reference standard, it employs a new excitation coil and data processing methods to achieve quantitative measurements without disassembling the vacuum switch. This tester boasts high precision and sensitivity (up to 10-5Pa) and features multiple unique functions, including built-in measurement curves for various domestic and international vacuum arc chambers, leakage current processing, complete air leakage discrimination, and a comprehensive input protection circuit.

The product features are detailed as follows:

Ionization Charge-based Sampling Technology: This technology accurately calculates the vacuum degree within a vacuum interrupter by measuring the ionization charge, significantly enhancing measurement accuracy compared to the traditional method based on ionization current peak.

Built-in Measurement Curves: The tester is equipped with measurement curves for almost all vacuum arc chambers, both domestic and international, eliminating the need for additional settings or calibration. It is directly applicable to various models of vacuum arc chambers.

Leakage Current Management: By initiating high voltage twice, the leakage current is effectively eliminated, ensuring the accuracy of measurement results, particularly during vacuum arc chamber measurements on the entire unit.

Complete Leak Detection: The tester can determine whether the vacuum interrupter is completely leaking by means of high-voltage breakdown, providing users with a convenient detection method.

Enhanced Input Protection Circuit: The signal input terminal of the tester now features comprehensive protection circuits, capable of withstanding electrical shocks caused by the breakdown of high-voltage vacuum arc chambers, safeguarding the testing equipment from damage.

In terms of technical specifications, the tester's measurement range spans from 10-5 to 10-1 Pa, with measurement errors less than 10% within the range of 10-4 to 10-1 Pa, and a resolution of 10-5 Pa. Additionally, the tester boasts wide environmental adaptability, allowing operation within a temperature range of -20°C to 50°C, with relative humidity not exceeding 85% RH, and compatibility with AC input power of 220±10% 50/60 Hz. Its dimensions are 350x320x225mm, making it portable and easy to operate.

The Vacuum Switch Vacuum Degree Tester is a powerful, easy-to-operate, and accurate specialized testing instrument, widely used in departments such as power, steel, petrochemical, textile, coal, and railway sectors that utilize vacuum switches.
