Wearing VR glasses, the first perspective and three -dimensional picture make the line situation look more intuitive and clearer, which is convenient for inspectors to quickly discover the defects and fault points. It can also be clear at a glance on whether the external force destruction measures for the line are in place. , Make risk prevention higher.

The new type of drone used with VR glasses is small and easy to carry.

Application field

Power distribution transformer energy efficiency detection

Innovative skills

Improve the efficiency of detection and reduce the cost of detection

Realize fast detection of key quality parameters of large -scale power distribution transformers

The power distribution transformer is the last ring that connects the user. In the past, the energy efficiency detection of the power distribution transformer required 3 employees to use at least 3 instruments in turn in the fixed station in turn, and the complex wiring was operated to complete the test. If the error line occurs during operation, the detection efficiency will be reduced.

With this tester, you only need to connect the test cable of the tester to the distribution transformer wiring terminal, and then click the "start measurement" key in the test system to automatically complete the energy efficiency test items of the distribution transformer.

The instrument can also intelligently judge the energy efficiency of the power distribution transformer and realize the one -click generation and upload of the report. Using this instrument, the Jiangsu Academy of Electric Sciences has completed the energy efficiency testing of more than 7,000 power distribution transformers this year, which will effectively ensure the safe and reliable power supply during the peak summer of Jiangsu Province.

Application field

Infrared detection of power equipment for substation

Innovative skills

Improve the "physical examination" efficiency of power equipment

Realize infrared charging detection

"Intelligent diagnosis at 1 second,

Reconstruction of the refined hot field,

Conclusion instant generation "

In the past, the staff used traditional infrared detection equipment to detect electrical equipment such as transformers and current transformers, and massive image data was generated, which was time -consuming and labor -intensive.

And the infrared intelligent imaging detection equipment can help staff to identify common devices, detect the equipment nameplate information, and save the tedious manual recording links of the staff; use the intelligent algorithm directly to accurately divide the contour of the equipment at the work site to extract the digital temperature of the target area; use Edge computing technology analysis and judging whether the device is abnormal.

Compared with traditional equipment, the equipment is lighter, smaller, and more compact internal structure. At present, the equipment has been applied at the infrared inspection site of 500 kV and above power stations and stations in Shanghai 10 to help staff reduce inspection time by about 80%.

Application field

Disassembling of the secondary cable for substation

Innovative skills

Use the instructions of the device to achieve

100%correctly and reliable one by one

Demolition secondary line

The small, light, and clever "anti -error disassembly erroneous secondary device" is installed on the traditional screwdriver, and the light, straight, quasi, and Mingying of the projection indicates that the light can quickly and accurately disassemble the secondary line.

Applying this device can not only improve the efficiency of secondary -time wiring operations, standardize the overall wiring process, but also alleviate the eye fatigue of the operator.

At present, this device has won a practical new patent and won the second prize of the results of the National Grid Hunan Electric Power's Excellent QC Group, and the third prize of the National Electric Power Industry Management Group Award.

Application field

Monitoring and innovation skills of the main equipment such as transformers such as transformers

No need to contact, it is like a stethoscope

Extract feature information from the sound pattern signal

Determine the running status of the device

This is the first transformer sound pattern intelligent collection and identification equipment in Fujian. It was jointly developed by the Chinese Academy of Electrical Sciences, the Fujian Academy of Power Science and Technology, and Putian Power Supply Company in Fujian.

This device can track, judge and early warning of the operating conditions of the primary transformer, so that operation and maintenance personnel can master the health state of the main transformer at any time and make scientific decisions and disposal, which greatly improves operation and maintenance.

Status monitoring and fault detection

Innovative skills

The voltage of remote informed low -voltage switch,

Current data and cable temperature information

In the past, after the power distribution and operation and maintenance personnel excluded the low -voltage switch, they would close the switch to send the electricity. After that, you need to go to the site to measure the temperature and load multiple times during the peak period of load to ensure that the fault is completely excluded.

The intelligent diagnostic instrument of this low -voltage power distribution line can remotely know the voltage, current data and the temperature of the cable of the low -voltage switch. This information can be pushed to the power distribution and maintenance personnel within 15 seconds to ensure that the operation and maintenance personnel master the line in real time. , Equipment operating status and efficiently carry out operation and maintenance.

At present, this device has been piloted in multiple power stations in Fuzhou and Xiamen, and has been authorized by the national invention patent, 1 national utility model patent authorization, and won the first prize of the national excellent quality management achievements, the State Grid Fujian power quality quality Management results first prize awards.
