ZXZH-IK: Advanced Multi-Parameter SF6 Gas Analysis

The ZXZH-IK Multiple Function SF6 Gas Analyzer represents a significant advancement in the comprehensive monitoring and diagnostic capabilities for SF6 gas-insulated electrical equipment. Designed for field technicians and engineers, this instrument integrates the analysis of gas purity, moisture (dew point), and key decomposition products into a single, robust, and portable unit.

Core Technological Capabilities

At its heart, the ZXZH-IK leverages high-performance sensor technology to deliver accurate and reliable data:

1.Precision Humidity Measurement: Utilizing a high-quality VAISALA dew point sensor, the instrument measures moisture content from -80°C to +20°C. It features automatic conversion of measured micro-water values to the standard reference of 20°C, which is critical for accurate condition assessment and inter-laboratory comparison. With an accuracy better than ±0.5°C and high resolution (0.1°C/0.1 ppm), it ensures precise tracking of moisture ingress, a primary cause of equipment failure.

2.Comprehensive Decomposition Product Detection: The analyzer is equipped with specific sensors for critical SF6 by-products:

SO₂ & H₂S: Detection from 0 to 100 µL/L with a sensitivity of ±0.5 µL/L. These gases indicate active arc or corona discharges within the equipment.

CO: Measurement from 0 to 500 µL/L (±1 µL/L sensitivity), often indicating involvement of organic materials (e.g., epoxy resin) in an internal fault.

HF: Detection from 0 to 10 µL/L (0.1 µL/L sensitivity), a highly corrosive by-product of discharges involving fluorine.

3.High-Accuracy Purity Analysis: The SF6 purity measurement range is 0 to 99.99%, with a high accuracy of ±0.1% within the critical 90% to 99.99% range. This allows for the precise assessment of gas quality and the detection of air ingress.

Design and Operational Features for Technicians

Engineered for the demands of field use, the ZXZH-IK incorporates several user-centric features:

Robust Data Management: The capability to store up to 1000 test records allows for extensive field campaigns without the need for frequent data offloading. The integrated file system and data query functions simplify historical analysis and reporting.

Intuitive User Interface: A large color LCD touchscreen provides a clear display of real-time measurements, historical curves, and system status. The graphical curve display offers an intuitive way to observe measurement trends and stability.

Durability and Reliability: The instrument is designed with anti-pollution and anti-interference characteristics. The probe is protected by a stainless-steel sintered filter, and advanced sensor protection functions enhance longevity in harsh electrical substation environments.

Portability and Flexibility: Weighing 6.5 kg and featuring a compact form factor, the analyzer is easy to transport. It operates on a 24V lithium battery, providing power autonomy for field measurements, complemented by 220V AC operation for lab use.

Technical Specifications Summary
