Ultrasonic judgment principles
(1) The main judgment basis is the partial discharge sound characteristics heard in the earphone during the detection, and the judgment is based on the sound continuity, high and low frequency, etc;
(2) Using the amplitude and related waveform maps of the displayed interface during the detection process as auxiliary judgment means;
(3) Use the effective value/peak value and 50Hz/100Hz frequency correlation displayed on the interface during the detection process as auxiliary judgment methods.
Principles for judging transient ground voltage
(1) If the difference between the detection results of the switchgear and the environmental background value is greater than 20dBmV, the cause needs to be identified;
(2) If the difference between the detection results of the switchgear and historical data is greater than 20dBmV, the cause needs to be identified;
(3) If the difference between the detection results of the switchgear and those of adjacent switchgear is greater than 20dBmV, the cause needs to be identified;
(4) If necessary, diagnostic tests such as local discharge positioning and ultrasonic testing are carried out.
1. The modular design of the partial discharge sensor (universal ultrasound, remote ultrasound, transient ground voltage) enables multiple means of partial discharge detection.
2. Equipped with laser aiming and positioning function to achieve precise positioning of fault points, and equipped with a 100 million pixel camera, it can capture and record fault point information in real-time.
3. It has the display function of gradient color map, curve map, feature map, phase map, etc.
4. The cloud platform can conduct real-time statistics on instrument data, facilitating the work leader to comprehensively grasp important data such as inspection progress and failure rate.
5. Use the analysis host to collect location information and generate operation and maintenance maps as needed to form equipment ledger information and comprehensively grasp the regional operation status.
6. Built-in relevant electrical equipment parameters, fault types, etc. can be entered into the line ledger in advance.
7. It can be compatible with the detection data of other devices, such as distance measuring instruments, grounding resistance testers, etc.
1.Is your company a sales company or a manufacturer?
We are an industry and trade enterprise, with our own factory and self-production and self-sale. The company was founded in 2005 and has 20 years of production experience. The company has reliable production lines, test laboratories and R&D centers.
2. Whether the goods are in stock, whether they can be customized, and how long the delivery period is.
After the goods are ordered, if there is no accident, it will take about 5 working days for production, and the delivery time is about 30 working days.
3. Is the quality guaranteed?
