First, SF6 qualitative leak detector

The SF6 gas leak detector adopts advanced digital signal processing system, and the detection frequency of the sensor head can reach 2000 times/second. Automatic reset, precise mechanical pump and visual display speed and simplify the leak search process; New sensing head corresponding to other products, improve sensitivity, reliability, service life; Linear design, beautiful and comfortable, more humane.

Unique sensitivity adjustment, original tracking leakage point, power display, simple operation, easy to carry, fully intelligent, anti-pollution, anti-interference, good repeatability, fast response, high sensitivity, high stability, microprocessor control, with advanced digital signal processing, three-color visual display, including noise suppression features, seven levels of sensitivity, Available up to 64 times the order of magnitude, cordless and portable, operated with two C batteries, touch keyboard control, includes carrying case, real-time sensitivity adjustment.

Second, SF6 quantitative leak detector

SF6 quantitative leak detector has high sensitivity, good stability, fast response speed, simple operation, large moving range, and can quickly and accurately detect the leakage point and annual leakage rate of SF6 circuit breaker and GIS qualitatively and quantitatively. It is suitable for power supply department, installation and maintenance unit and electric power test research institute.

Main feature

1. Small size, light weight, easy to transport and carry.

2. The instrument is light and compact, can detect higher leakage points, and has a large moving range.

3. High sensitivity: Optimized design is adopted on the high road, while reducing noise and electromagnetic wave interference, so that the sensitivity is improved.

4. Wide measuring range, multi-gear switching: the instrument can detect the leakage of SF6 within the leakage rate range of the SF6 switching device, can be switched to multiple gear selection, and give the standard curve of each file, can be quantitative and qualitative leak detection.

5. High accuracy: The instrument adopts advanced calibration method to verify and give a high accuracy standard curve, which improves the reliability of SF6 leak detection results and the accuracy of quantitative leak detection.

6. Display intuitive, sound and light alarm: the use of indicator display, with a simple and intuitive effect. When SF6 gas is present, the instrument emits an audible and visual alarm.

7. Fast reaction speed, short recovery time: The use of new circuit structure, the reaction speed of the instrument is accelerated, the recovery time is shortened, which greatly facilitates the field detection.

8. Built-in self-diagnosis function: The instrument has the function of monitoring the working state of the instrument itself.

9. Beautiful appearance: All button switches on the board are indicated by the indicator light.

10. Long use time: the use time can be up to 3 hours, which is very suitable for on-site, SF6 high voltage switch factory and research institute.

11. Strong anti-interference: the instrument adopts full shielding to eliminate interference from the outside world and itself.

12. High stability: high voltage stability of the instrument power supply, low temperature, small heat loss, good thermal stability. During the use time of the instrument, the zero drift and range drift of the instrument are small.

13. High detection accuracy, minimum detection value: 0.01μL/L, detection range: 0~30μL/L.

14. Good repeatability: The repeatability of the instrument is good after multiple measurements.

15. High reliability: instrument circuit structure is reasonable; Imported components are used, and strictly screened, in addition, it is equipped with overcurrent and short circuit protection.

Third, SF6 laser leak detector

SF6 laser leak detector is characterized by strong absorption of far infrared by sulfur hexafluoride gas. Combined with infrared laser spectroscopy technology, laser scanning imaging technology, infrared image and visible image fusion processing and other new technologies, it can quickly find and locate the leak point, and carry out scientific maintenance and diagnosis for SF6 light station. To improve the efficiency and quality of equipment maintenance, improve the level of maintenance technology, ensure the personal safety of personnel and reduce the pollution caused by SF6 gas leakage to the environment and other problems.

The working principle is that SF6 gas has a strong absorption capacity for long-wave infrared, and infrared laser is used to irradiate the surface of the equipment to be tested, and the image generated by its reflected light is observed on the laser imaging viewfinder. When running, the SF6 leak point will be visually displayed on the LCD screen, and the SF6 leak point will be accurately locked through the unique intelligent identification technology, so that the operator can intuitively and quickly locate the leak location. The SF6 leak point can be locked quickly, accurately and intelligently, which can improve the efficiency and accuracy of SF6 leak detection.

SF6 infrared imager

The SF6 infrared imager uses a refrigerated quantum well detector to make use of SF6 gas and background temperature difference imaging, which has been sold in China and has been tested on site for many times, belonging to passive infrared technology. The instrument has the advantages of small size, light weight, no laser, high sensitivity, accurate location of the leak point, and can also be used for SF6 gas leak detection and equipment temperature detection.

The SF6 infrared imager can quickly scan large areas of electrical equipment filled with SF6 gas, even several kilometers of pipes, and this special infrared thermal imager can generate infrared images of gas leaks in real time. The leaking gas will appear as "black smoke" on the screen, so you can determine whether there is SF6 gas around the device being tested.

The SF6 infrared thermal image leak detector uses innovative technology to translate the physical properties of VOC gas leaks so that leaking gases that were previously invisible to the naked eye are now clearly visible and can be recorded into any image memory for simple archiving, verification and email. Infrared thermal imager that can record in real time, scanning speed of 50HZ PAL or 25 images per second. Compared to scanning several kilometers of pipe on a moving vehicle or panoramic view of a large area of pipe system, inspection with an infrared thermal imager will greatly improve efficiency.
