SF6 online leak alarm system accurately measures SF6 gas concentration in real time

SF6 gas is widely used in medium and high pressure equipment. For SF6 gas is heavier than air, leakage is easy to accumulate, and it is easy to cause problems such as lack of oxygen in low-level space and the threat of toxic air to personnel. Industry safety regulations clearly stipulate that when entering the SF6 power distribution device room, personnel must first ventilate for 15 minutes, monitor the SF6 concentration and oxygen content in the air, and install an oxygen meter that can alarm in the low area of ​​the SF6 power distribution device And SF6 gas leak alarm.

SF6 online leak alarm system uses negative ion capture technology to continuously detect SF6 concentration, O2 content, temperature and humidity in the GIS room environment. The imported imported oxygen sensor has two built-in SF6 detectors to ensure zero false alarm rate. The monitoring points and other functions can be expanded according to user needs. Five independent ventilation systems can be programmed. Any door in the GIS room can be set to enter and can be remotely monitored. Platform contact.

The SF6 online leak alarm system uses an open system platform with an open optical path and high-sensitivity mid-infrared laser absorption spectroscopy technology, data acquisition and processing, and communication technology. All its functions adopt a modular design, which facilitates engineering installation and engineering maintenance. The system comes with an automatic concentration calibration function, and no additional periodic calibration is required.

The SF6 online leak alarm system uses a combination of ultrasonic sound velocity measurement and attenuation method to quantitatively and real-timely measure the SF6 gas concentration. Accurately obtain the SF6 content in the gas.

The main function of the host is to complete data collection, data display, data storage, sending control instructions, alarm instructions, data upload, soft and hard reset, etc. The host is equipped with an operation panel and a display interface, with flexible human-machine communication functions.

Functions and features:

1. Real-time on-line monitoring of SF6 and O2 concentration.

2. When the system monitors the SF6 gas over the concentration index, it will automatically turn on the fan and sound and light alarm.

3. When the system monitors O2 gas below the concentration index, it will automatically turn on the fan and sound and light alarm.

4. Real-time online monitoring and display of indoor temperature and humidity.

5. The system can set the function of the fan to start and stop at multiple times every day.

6, through the infrared detection device, identify the staff entry, automatically turn on the fan and voice prompts.

7, the system can be equipped with LED dynamic display, multi-channel display of SF6 and O2 gas concentrations, and supports voice broadcast.

8. The system has large-capacity data storage, with historical event storage and query functions.

9, the host has a large screen LCD display, full Chinese operation interface.

10. With RS485 communication interface, the system can realize long-distance online monitoring and control.
