SF6, namely sulfur hexafluoride, is commonly utilized in medium-voltage and high-voltage equipment. It is heavier than air, indicating that if SF6 leaks, it will accumulate in lower locations, and this is a great threat to human safety.

Given this, our MRD-6QC SF6 gas leak detector and alarm system is specifically designed to detect the presence of SF6 in air, and the annual production capacity is over 600 sets. This SF6 leak detection system has been successfully used in many projects or enterprises around the world, such as CSR Sifang Co., Ltd., Tianjin JL Railway Transport Equipment Co., Ltd., Tagaung Taung Nickel Mine Project in Myanmar, etc.

Advantage
1. The SF6 leak detector makes use of MRD5200/5300 sampler to measure SF6 concentration after collecting oxygen and SF6 from an enclosed area, and then these data are delivered to the main controller via RS485 bus. After calculation, the controller will send signals to start, stop, or regulate the rotation speed of draught fan. What is more, the detection result can be displayed, and it also can be uploaded to upper control system.

2. Due to its strong anti-interference ability, fast detection speed and trustworthy algorithm, our SF6 gas leak detector and alarm system will not give false alarms, and it won't fail to give alarm as well when SF6 concentration is higher than the alarm point.

3. We have 6 years of production experience in this field, and this makes us capable of maintaining constant product quality.

4. Aside from superior product, timely after-sales service is also what we promise to offer. Under the condition that there is something wrong with our gas monitoring instrument, please call us and we would like to offer help through the phone. If your problem isn't solved, we will send technicians for field inspection within the warranty period.

Function
1. Traditional SF6 detection methods are easily affected by ambient temperature and humidity, but our SF6 gas leak detector and alarm system successfully overcomes this disadvantage, and it features fast response, high precision, excellent stability and long service life (10 years).

2. The sulfur hexafluoride leak detector realizes self-diagnostic testing, and it could tell even very subtle concentration change of SF6 in the gas insulated switchgear (GIS). Meanwhile, it also provides trend analysis of gas concentration and monitors working environment.

3. Thanks to the audio function and large display screen, users could communicate with this gas leak alarm system in an exceptionally convenient way.

4. Our SF6 gas leak detector and alarm system is outfitted with an infrared sensor, and it could start audio system and draught fan automatically.

5. As a result of the timing control function of draught fan, the waiting time before entering into GIS is shortened, thus greatly enhancing the overall working efficiency.

6. Operators are allowed to adjust the inspection interval; and the testing point tracking function can be strengthened automatically.

7. When SF6 leakage is detected, the draught fan will be started automatically, and both audio and visual alarms are activated to provide clear indication.

8. Remote control is achieved through telecommunication with computers in the monitoring room, so there is no need for operators to check data on site.

9. The SF6 gas leak detector and alarm system is compliant with RS485 communication protocol, while both remote metering and remote signalling are realized by the RTU (remote terminal unit). On the other hand, discrete output is adopted for alarming, and our product works perfectly with SAC, NARI, XJ, SIFANG and other integrated automation systems (SAC: Guodian Nanjing Automation Co., Ltd., NARI: NARI Technology Development Co., Ltd., XJ: XJ Electric Co., Ltd., SIFANG: Beijing Sifang Automation Co., Ltd.).

10. The large storage capacity allows for convenient data storage and inquiry, which makes it possible to analyze measurement data.
