TK8000 SF6 Leakage Quantitative Alarm System

SF6 gas is a stable greenhouse gas that has been discovered so far. Experiments have proved that it has a strong spectral absorption characteristic at 10.5um. SF6 laser transmitter uses carbon dioxide laser,

Advanced design methods and technologies such as narrow-band filters, high-sensitivity and low-noise photoelectric detection circuit, stable optical chopper, reference optical path and open optical path structure realize the SF6 gas in the area to be measured

Real-time, online high-sensitivity infrared laser spectroscopy remote measurement of concentration. SF6 laser transmitter is based on the analysis and comparison of relevant gas detection methods in the same industry at home and abroad, and the advanced open optical path is high.

Sensitive mid-infrared laser absorption spectroscopy technology is applied to SF6 gas detection, and the technical level has reached the international leading level. The intelligent SF6 laser transmitter comprehensively uses the open optical path and highly sensitive mid-infrared laser absorption

An open system platform that integrates spectrum technology, data acquisition and processing, and communication technology. All of its functions are modularized, which is convenient for project installation and project maintenance. The system itself has automatic concentration

The degree of calibration function does not require additional periodic calibration.

       1. The laser transmitter is composed of an intelligent analog quantity collector, a laser emission and light intensity monitoring unit, a laser receiving unit, a signal processing unit, etc., to achieve real-time monitoring of the concentration of SF6 gas in the air in the area

The purpose of the degree;

       2. Quantitative detection and analysis function of SF6 gas in the regional air (using the open optical path high-sensitivity mid-infrared laser absorption spectroscopy technology, eliminating the laser's own intensity fluctuations and the influence of the external environment

ring);

       3. Real-time display of the SF6 gas concentration value in the air in the area, and set the alarm concentration arbitrarily. When the SF6 gas concentration in the environment exceeds the set alarm value, an over-standard alarm function will be issued;

       4. Each SF6 gas laser detector can monitor the change of SF6 concentration in the range of 0.1～200m, without any sampling device, only one reflector, the laser passes through the area to be monitored

After being reflected by the reflector and reaching the detector, the measurement of the SF6 concentration in the entire optical path is realized;

       5. Using laser spectrum absorption technology to detect SF6 gas leakage, the measurement accuracy can be higher than one part per million, the detection resolution can reach the order of 1ppm, and it has good repeatability, stability and reliability.

Long service life, quantitative analysis, using open optical path technology, avoiding sampling and realizing large-scale continuous space monitoring, simple operation and low failure rate.

       6. Mechanical and electronic multiple protection design, safe and reliable;

       7. Designed for piercing cables, beautiful appearance, directly fixed on the cable, safe and convenient, installation at any angle;

       8. The power supply adopts the general dry battery, which is suitable for use in the field without power supply. At the same time, it ensures the complete isolation of the piercer from the power system to ensure the safety of power supply.
