The working principle and product characteristics of SF6 comprehensive tester

The SF6 comprehensive tester is a three in one instrument that integrates humidity, purity, and decomposition product measurement. The following is a detailed introduction to the SF6 comprehensive tester:

1. Working principle

The working principle of SF6 comprehensive tester is mainly based on the principles of resistance capacitance method and electrochemical sensors. By integrating advanced sensor technology and microprocessing technology, it achieves the detection of multiple indicators such as humidity (dew point), purity, and decomposition products of SF6 gas.

① Resistance capacitance method: Humidity measurement adopts the resistance capacitance method, which uses the principle of the electrical parameters of hygroscopic substances changing with humidity for measurement. Humidity sensors typically use DRYCAP from VAISALA, Finland ® Sensors, which have been used in industrial humidity measurement for many years, have high precision, high stability, and strong anti pollution capabilities.

② Thermal conductivity sensor: Purity measurement usually uses thermal conductivity sensors, which can accurately measure the impurity content in SF6 gas and determine its purity.

③ Electrochemical sensors: The measurement of decomposition products (such as SO2, H2S, CO, etc.) uses the principle of electrochemical sensors, which work by reacting with the measured gas and generating an electrical signal proportional to the gas concentration. Electrochemical sensors have high sensitivity and good stability, making them suitable for detecting the products of SF6 high-temperature decomposition, and typically have fast response times.

2. Product Features

① Comprehensive testing function: The humidity, purity, and decomposition product testing functions are centralized on one instrument, greatly saving gas usage, reducing user workload, and improving work efficiency.

② High precision and fast response: We use the best sensors from abroad, such as Vaisala’s humidity sensor from Finland, HNP’s purity sensor from Germany, and Alpha SF6’s decomposition product sensor from the UK, to ensure the accuracy of measurement results and fast response.

③ Intelligent operation: The instrument is equipped with a built-in rechargeable battery, supports both AC and DC, uses a large LCD Chinese display, displays various parameters in real time, operates in a foolproof manner throughout the process, stores massive information, and is easy for users to use and maintain on site.

④ Data management: Built in data storage and communication interface, convenient for data management and transmission, supports on-site printing and remote monitoring.

⑤ Equipment maintenance: Through strict testing of various indicators of SF6 gas, potential problems can be detected in a timely manner to ensure the safe and stable operation of power equipment.

⑥ Fault diagnosis: When equipment malfunctions, the SF6 comprehensive tester can quickly locate the problem, help maintenance personnel handle the fault in a timely manner, and restore the normal operation of the equipment.

3. Precautions for use

① Before using the tester, carefully read the operating manual to understand the operating methods and precautions of the instrument.

② During the detection process, the ambient air should be kept free of interference factors such as smoke and dust to ensure the accuracy of the detection results.

③ The tester should be regularly maintained and serviced, including cleaning the probe and checking the battery level.

④ When using the tester, attention should be paid to safe operation to avoid damage to the instrument or injury to personnel.

In summary, the SF6 comprehensive tester has significant advantages in SF6 gas detection in industries such as power, chemical, and metallurgical due to its comprehensive testing function, high-precision measurement capability, convenient data storage and printing function, and durable design.

The ZC-318B SF6 comprehensive tester uses imported sensors with reliable performance as sensitive components. The humidity sensor adopts Finnish VAISALA company’s humidity sensor, and the purity, SO2, H2S, CO, HF and other sensors adopt British ALPHA company’s thermal conductivity sensor and electrochemical sensor; At the same time, it is equipped with the most advanced ARM development technology, precision sensors such as mass flow sensors and temperature sensors, making the sampled data more realistic, reliable, and faster in operation. The device integrates real-time measurement, curve display, power management, time system, file system, data query, data printing and many other functions, integrating advanced sensor technology and information technology at home and abroad, humanized operation and perfect functions. The instrument adopts a color LCD display screen, with a friendly, beautiful interface and easy operation.
