Deep analysis of SF6 comprehensive analysis gas testing instrument for sulfur hexafluoride

The SF6 comprehensive analysis gas tester is a three in one instrument that integrates humidity, purity, and decomposition product measurement. It has the characteristics of high precision, multifunctionality, and portable design.

1. Main features

① High precision sensors:

The humidity measurement adopts high-performance sensors, such as the sensor from Vaisala in Finland, with an accuracy of ± 0.4 ℃ (when the dew point temperature is below 0 ℃, the sensor output is frost point).

Purity measurement uses sensors with temperature compensation, such as the sensor from Germany’s HNP, with an accuracy and repeatability of ± 0.4%, independent of flow rate.

The measurement of decomposition products uses imported SF6 specific sensors, such as the Alpha sensor from the UK, which can accurately measure the content of decomposition products such as H2S and SO2 with an accuracy of ± 1ppm.

② Multi functional integration:

Integrating humidity, purity, and decomposition product measurement, three indicators can be tested in one on-site measurement, greatly saving gas usage in equipment, reducing user workload, and improving work efficiency.

③ Portable design:

Small size, light weight, easy to carry, suitable for on-site inspection.

Built in rechargeable battery, dual-use for AC and DC, convenient for use in different environments.

④ Intelligent operation:

Adopting a large LCD Chinese display, real-time display of various parameters, easy to operate.

Support functions such as data communication, measurement data storage, printing, etc., to facilitate subsequent queries and management.

Equipped with self diagnostic function to ensure the normal operation of the instrument.

3. Application Fields

The SF6 comprehensive analysis gas tester is widely used in the fields of power, railway, electrical manufacturing, chemical industry, etc. It is used to detect leaks and status of equipment and containers filled with SF6 or other halogen gases, ensuring the normal operation and safety of the equipment. Specific application scenarios include:

① In the field of electric power, it is used to detect the humidity, purity, and decomposition products of SF6 gas inside electrical equipment such as SF6 circuit breakers, transformers, GIS, and transformers, and to determine whether there are potential faults such as leakage and insulation performance degradation in the equipment.

② Railway field: used to detect SF6 gas insulation equipment in railway systems, ensuring the safety and stability of railway transportation.

③ In the field of electrical manufacturing, it is used for the production and quality testing of SF6 gas insulated electrical appliances to ensure that product quality meets standard requirements.

④ In the field of chemical engineering, SF6 gas monitoring and control are used in the chemical production process to ensure production safety and product quality.

summarize

The SF6 comprehensive analysis gas tester has been widely used in multiple fields due to its high precision, multifunctionality, and portable design. By integrating high-precision sensors and advanced detection technology, this instrument can achieve precise measurement of SF6 gas humidity, purity, and decomposition products, providing strong guarantees for the normal operation and safety of the equipment.

ZC-318 SF6 gas comprehensive tester is a set of SF6 humidity, SF6 purity, SF6 decomposition products testing in one, the original three instruments to achieve the function, concentrated in one instrument. One on-site measurement can complete the three indicators detection, greatly saving the gas in the equipment, reducing the user’s workload and improving the work efficiency.

The excellent performance of SF6 gas comprehensive tester is due to the use of the best sensors from abroad; pure imported high-precision humidity sensors are used for humidity, thermal conductivity sensors with temperature compensation are used for purity, and the decomposition products are also imported from Europe. Color LCD display, real-time display of various parameters, full touch, fool operation, mass information storage, built-in rechargeable battery, AC and DC dual-purpose.
