Please continue to browse down for more information
Zhenyuan ZY-DH100SF6 density micro-water online monitoring system adopts imported special high-precision low-humidity monitoring sensors, which can be used for GIS and SF6 circuit breakers of various voltage levels. It mainly monitors the temperature, relative humidity, pressure, density, and dew point in the SF6 gas chamber And other parameters. Real-time monitoring of SF6 gas in the air chamber cavity.
(1) High precision and high reliability
The transmitter uses imported high-stability sensors. The sensor is corrected and compensated by the internal circuit of the transmitter, and its output has good linearity and high accuracy. The external structure of the transmitter is also more suitable for measurement in high-frequency electric field environments. It is integrated with the circuit processing part to reduce interference coupling and improve the stability and reliability of the long-term operation of the circuit.
(2) Achieve online monitoring and monitoring and condition maintenance
The monitor can run on-line for a long time. Its equipped RS-485 / CAN communication interface can upload monitoring data to the monitoring center in real time. When the measured gas index exceeds the standard, the monitor will automatically upload the alarm or blocking signal to the remote monitoring center according to the preset threshold, or directly start the alarm and blocking device.
