Product Description

LK303 On Line Leakmeter system is based on the current power system to further improve production safety requirements, for the staff to provide the physical protection of health and safety which in the room installed SF6 distribution equipment, and the design, development of intelligent online detection system.

Information:

System is mainly detected in ambient air, the SF6 gas’ content and oxygen content, when the SF6 gas content exceed standard or the lack of oxygen in the environment,the system can real-time alarm, and automatically open to the ventilation fan and have the temperature and humidity testing, the work of the state of voice prompts, Far EasTone alarm, historical data query and many other rich features.
System uses the latest DNIR infrared sensor technology to real-time measurement of the concentration of SF6. Can be achieved not only the purpose of protection of personal safety, but also to ensure the normal operation of equipment; high stability of oxygen sensors for on-site staff to provide more reliable protection layer.
The system can be widely used in a variety of voltage levels of SF6 switch rooms, switchgear rooms (GIS Room), SF6 main transformer room.
System installation:
★ the whole system can be installed in the power state of equipment.
★ we responsible for on-site investigation, construction, installation, commissioning work, the user sent to custody at the scene.
★ users associations, we meet, conduct on-site inspection, record inspection results on behalf of the signing by the user.
★ construction after the completion of our responsibility to provide systems engineering plans within one week.

Network system:
In order to fully and accurately monitor the situation at the scene, the project-site monitoring in accordance with the scope, equipment, such as intensity of the actual situation, using the exhaust method, the various sampling points of the gas pumped into the trachea with focus on analysis of air chamber and at the same time analysis of a sample point of oxygen and SF6 gases.
For a 110KV change GIS rooms, the use of 6-channel detection of SF6 gas content and 6-channel detection of oxygen content, respectively, to monitor the switch 3.
System can be online displayed on the sampling point switch of the indoor SF6 and O2 concentration, when the switch indoor concentration of SF6 and O2 over the system alarm alarm threshold. (SF6 alarm threshold to 1000ppm, the value can also be carried out in accordance with Council requirements change, LK303 warning system detection limit is 200ppm, concrete construction can be adjusted according to user requirements. O2 alarm threshold is 19.6%.)

Main Advantages:
★ Detecting function of SF6 in ambient air, Alarm function when the value of SF6 is over the standard.
★ Detecting function of O2 in ambient air, Alarm function when the value of O2 is under the standard.
★ Forced ventilation function .while the value of SF6 is over 1000ppm or the value of O2 is under 19.6%,the ventilation fan will start to working.
★ Artificial setting alarm points
★ Detecting function of temperature and humidity in ambient air
★ The timing of ventilation function
★ Artificial ventilation function
★ Display function of last ventilation
★ Real time display each kind of parameter
★ Inquire function about historical data
★ Infrared detection and Voice notification function
