SF6 Leak monitoring and alarm system installation basis: GB/T8905-1996 "Guidelines for Gas Management and Detection in sulfur hexafluoride Electrical Equipment" and DL 408-1991 "Safety Work Regulations for Electrical Industry" (electrical parts of power plants and substations) and "Eighteen Major Anti-accident Measures for Power Grids of the State Grid Corporation" special provisions, The distribution unit room equipped with SF6 equipment must ensure that the SF6 gas concentration is less than 1000ppm, in addition to the installation of strong ventilation devices, must be installed with alarm oxygen meter and SF6 gas concentration detection and alarm meter.
Industry safety regulations:
Enter the engineering installation site, strictly follow the safety regulations of electric power operation. The person in charge shall explain the site safety measures, work content and safety precautions in detail to the construction personnel. The construction personnel shall obey the command of the guardian and the person in charge of the work. The guardianship personnel shall supervise and inspect the safety of the whole project, and stop the behaviors that violate the safety regulations. Those who do not listen to the advice shall be ordered to leave the work site.
Article 191 Power distribution rooms and SF6 gas laboratories equipped with SF6 equipment must be equipped with powerful ventilation devices. The air outlet should be set at the bottom of the room.
Article 192 In the room, when the equipment is filled with SF6 gas, the relative humidity of the surrounding environment should be less than 80%, and the ventilation system must be turned on to avoid SF6 gas leaking into the work area. The SF6 gas content in the working area air shall not exceed 1000ppm.
Article 196 The staff entering the SF6 distribution unit room must first ventilate for 15min, and measure the SF6 gas content with a leak detector, try to avoid one person entering the SF6 distribution unit room for inspection, and no one is allowed to enter the maintenance work.
Article 198 Entering the SF6 power distribution unit room low area or cable trench work should first test whether the oxygen content is qualified.
Article 199 An oxygen meter and an SF6 gas leak alarm meter shall be installed in the low area of the SF6 distribution unit. These instruments should be tested regularly to ensure their good condition.
Article 203 In the event of an emergency, all ventilation systems should be opened immediately for ventilation. In the event of a rupture of the explosion-proof film of the equipment, power should be cut off and the equipment should be wiped clean with gasoline or acetone.
SF6 leakage monitoring and alarm system supports infrared human body induction fan, while supporting voice infrared alarm oxygen content in the air monitoring and display function, SF6 gas content monitoring and display function in the environment.
SF6 gas concentration exceeds the limit alarm, sound and light prompt, SF6 gas content exceeds the standard or hypoxia, automatic exhaust air oxygen content detection when the leak, hypoxia alarm.
SF6 and oxygen can detect SF6 leak detector SF6 detector Halogen leak detector Halogen detector online automatic compensation and correction of errors caused by environmental changes, high measurement accuracy, good stability, no false alarm; High performance thermal conductivity sensor, accurately detect the amount of leakage, occurrence report
The alarm can monitor the operating status of the system through remote network, and directly control the operation of the host or transmitter, automatic timing exhaust and automatic exhaust of leakage exceeding the standard. Manual exhaust key control, the last exhaust time prompt, can also be automatically timed exhaust automatic monitoring of ambient temperature and humidity.
1.10.4 Large screen color background LCD display, humanized operation interface.
2. Dual gas detection, in line with the requirements of "Electrical safety work Regulations".
3. Long life design, save cost for customers.
4. Dual CPU structure design, monitoring and measurement more reliable, real-time.
5. The gas detection point can be expanded according to the needs, and can be connected with the computer to achieve remote monitoring, and the event record and historical data record detection point ring networking, easy to install wiring.
That is, there is:
1) Detection and display of excessive SF6 gas concentration;
2) Oxygen content detection and display;
3) SF6 and oxygen control function;
4) Temperature, humidity detection and display function;
5) Timely ventilation;
6) SF6 concentration and oxygen abnormal automatic ventilation;
7) Zone control fan;
8) Voice alarm and prompt function;
9) Audible and visual alarm function;
10) Large capacity data storage;
11) Historical data query function;
