Wuhan Electric North Branch Electric Co. BKJL-7Y-precision SF6 gas leak detector quantitative

I. Overview Wuhan Electric North Branch Electric Co. BKJL-7Y-precision SF6 gas leak detector is based on the views of the user feedback, combined with the actual situation of China's power system and well designed. In addition to overcome the shortcomings of the instrument of foreign products, absorbing its advantages, it also has a high sensitivity, good stability, fast response, simple operation, a large range of motion can be quickly and accurately leak qualitative and quantitative detection of SF6 circuit breakers and GIS Point and annual leakage rate. Instrument is suitable for the electricity sector, installation and maintenance units and Electric Power Research Institute to use. SF6 is also very suitable for high-voltage switchgear plant as SF6 electrical equipment and ancillary equipment exports. First, the major technical indicators 1, the minimum detection value: 0.01μ1 / 1 2, detection range: 0 ~ 30μ1 / 1 0 ~ 200μ1 / 1 0 ~ 500μ1 / 1 3, Response time: <1 sec 4, the recovery time: <10 5 seconds, showing error: ≤ ± 3% 6, Repeatability: ≤1% 7, stability: Zero Drift: <± 1% span drift: <± 1% 8, indicating the way: Indicates LCD display and sound and light table Signal 9 gun detection probe length: 4 meters 10, continuous working time: 3 hours 11 instrument power: 220V 50HZ 12, use of the environment: Temperature: 5 ~ 45 ℃ Relative humidity: ≤85% 13, Weight: 15 kg Second, the main features 1. Small size, light weight: the greatest possible use of lightweight materials, the compression of space and weight instrument, the instrument greatly reduced size and weight, easy to transport and carry. 2. Measure the segment length, it can detect leaks about 4 meters high, large movement range. 3. High sensitivity: Optimized design of the circuit, while reducing noise and electromagnetic interference, so that the sensitivity is improved. The measuring range, multi-file switch: The instrument can detect leakage of SF6 leakage rate in the range of SF6 switching device can switch between multiple files, and each file is given a standard curve, quantitatively and qualitatively leak. 5. High accuracy: The instrument uses advanced testing method validation, calibration curves are given high accuracy, improve the credibility of the results SF6 leak detection and quantification of leak detection accuracy. 6. visual display, audible and visual alarm: The LCD instrument display, with a simple and intuitive results. When SF6 gas is present, the instrument audible alarm. 7. reaction speed, recovery time is short: A new circuit configuration, the instrument of reaction speed, recovery time, which greatly facilitates the on-site inspection. 8. Built-in self-diagnostic function: This instrument has the instrument to monitor the status of their work functions. 9. Use a long time: the use of time of up to three hours, is very suitable to live, SF6 high voltage switch factory and research institutes to use. 10. Strong anti-interference: The instrument uses fully shielded, eliminating external and interference itself. 11. High stability: the instrument supply voltage, high stability, low temperature, low heat loss, good thermal stability. Time in the instrument, the instrument zero drift and span drift. 12. repeatability: many instruments to measure its results and good reproducibility. 13. High reliability: instrumentation circuit structure is reasonable; the use of imported components, and a rigorous screening, the other comes with overcurrent, short circuit protection.
