Microcomputer based SF6 micro water tester, portable gas micro water measuring instrument, intelligent imported micro water measuring instrument, micro water meter

Description :

The UAWS-S high-precision SF6 micro water measuring instrument, also known as SF6 gas micro water measuring instrument, SF6 gas micro water measuring instrument, SF6 gas micro water testing instrument, SF6 intelligent micro water measuring instrument, and SF6 micro water testing instrument, is developed by Wuhan Wei'an Electric Power R&D Center based on the on-site usage requirements of DL/T506-2007 "Measurement Method for Insulation Gas Humidity in SF6 Electrical Equipment". It adopts high-precision dew point sensor and digital circuit control technology, and can accurately measure the trace moisture content in SF6 gas as a high-precision intelligent testing instrument. This high-precision SF6 micro water measuring instrument also comes with an automatic dryer, which is widely used in units and departments such as petroleum, power, metallurgy, environmental protection, scientific research institutes, and power construction.

The high-precision SF6 micro water measuring instrument is equipped with multiple connectors and self-locking contacts imported from Germany. All connectors are made of pure copper and alloy materials, which are safe and reliable, leak free, and ensure data accuracy and reliability. The SF6 micro water measuring instrument is easy to operate, with fast response time and short measurement cycle during the testing process, intuitive display, and adopts intelligent self calibration technology. It has a wide measurement range, fast response speed, high accuracy, good linearity, and dynamic display of measurement curves. At the same time, this tester also comes with an automatic dryer, which can greatly shorten the measurement time.

Main features of microcomputer based SF6 micro water tester

1. High stability: The SF6 micro water meter can maintain stable measurement data within ± 0.5 ℃ under severe interference conditions, and has long-term stability and good repeatability

　　2. High precision: This SF6 intelligent micro water measuring instrument adopts an imported high-performance dew point sensor and a high-speed 12 bit ∑ - Δ AD analog-to-digital converter, with a resolution of 0.1 ℃, fully meeting the actual measurement requirements. Reliable measurement results, wide measurement range, fast response speed, and stable and reliable measurement results are achieved throughout the entire range

　　3. Intelligence: Self calibration upon startup, sensor probes can automatically calibrate the zero point, eliminating system errors caused by zero drift and ensuring measurement accuracy

　　4. Multiple protection: Equipped with an oil filter device, it is not affected by dust particles and most chemical pollutants, and can provide anti oil protection for sensors, making it extremely suitable for use in industrial environments. The dryer can effectively protect the dew point sensor probe and extend the service life of the sensor

　　5. Fast gas saving: After the SF6 intelligent micro water measuring instrument is turned on and enters the measurement state, the dew point value measurement time is 3-5 minutes. The SF6 micro water measuring instrument requires drying of the pipeline and sensor, which takes slightly longer

　　6. Powerful features: 4.7-inch true color touch LCD display, fully Chinese operation interface. Directly display dew point value (℃), micro water value (uL/L), date and time, and dynamically display dew point measurement curve. Real time saving of measurement data, up to 100 sets of measurement data can be stored

　　7. Communication function: This SF6 intelligent micro water measuring instrument has an RS232 interface that can be connected to a PC serial port, making it convenient for the PC to further process the data

　　8. Easy to use: This SF6 intelligent micro water measuring instrument uses self-locking connectors imported from Japan, which are easy to plug and unplug, safe and reliable, and leak free. Sensitive touch sensitive buttons facilitate operation and improve work efficiency. Built in large capacity rechargeable lithium battery, small size, light weight, easy to carry

Technical parameters of SF6 micro water tester

Precautions for SF6 micro water measuring instrument

The SF6 micro water measuring instrument should be placed in a safe location to prevent damage from falling. Avoid severe vibrations

Can't detect corrosive gases

When adjusting the gas flow rate, the flow valve should slowly open to indicate a flow rate of around 0.5L/min

Before use, it should be charged in a timely manner, and the charging time generally takes more than 4 hours

Try to avoid testing at high temperatures as high temperatures can affect the accuracy of measurements

When not in use for a long time, the sensor should be turned on regularly to dry

Water content testing standard for SF6 gas circuit breakers

SF6 circuit breakers should be measured for moisture content in the breaking unit and support unit separately during factory and major repairs (before overall reassembly), with a value of ≤ 150

During the handover, measure the water level of the circuit breaker at the lower inflation interface of the pillar, which should be ≤ 150

During operation, the moisture content of the circuit breaker is measured by the lower inflation interface of the support pillar. The testing cycle shall be in accordance with the "Pre Trial Regulations" and shall be ≤ 200

During operation, if necessary (such as leakage of the disconnecting unit or disassembly of the disconnecting unit), the SF6 circuit breaker should have the water content of the disconnecting chamber measured separately at the self sealing joint inside the junction box, which should be ≤ 300
