At the 500-kilovolt Caopu substation on the Kunming Power Supply Bureau, a white patrol robot about 1 metre in length walked forward, stopping to lift the "head" and using two "eyes" to look at the outdoor switch. Plant equipment, take pictures, read data. In February of this year, the Kunming Power Supply Bureau established the first robotic working group of the South Network, which will promote the patrol robots on a global power transformation business. This is the first power supply system in Yunnan Province that conducts a large-scale promotion of inspection robots. Bureau. In 2018, Kunming Power Supply Bureau plans to invest 7 patrol robots.
Patrol robots are all high-tech
Recently, Kunming Power Supply Bureau 500kV grass shop substation appeared a white patrol robot about 1 meter high. In order to make cooperation with robots enjoyable, Chen Dekai, the head of the power transformation management team at the Kunming Power Supply Bureau's Robotics Working Group, is constantly communicating with robot factory workers to debug robots.
Do not look at patrol robots are small, but all are high technology. Chen Dekai introduced that the substation intelligence patrol robot mainly includes two parts: the background monitoring system and the robot body structure. The robot structure contains the two parts of the inspection platform and the mobile platform, which is the "head" and "body" of the robot. The “body†is responsible for the movement and positioning, through the front of the ultrasound radar intelligent barriers, equipped with a panoramic laser scanning device at the rear, timely analysis of real-time traffic conditions, stop at the exact detection position.
The “head†is responsible for detection, mainly including visible light cameras, infrared cameras, pickups, etc. The detection head can reach an elevation angle of 90 degrees, a depression angle of 10 degrees, and a rotation of 180 degrees to achieve functions such as photographing and video recording.
"The robot can achieve visible light photography, equipment appearance, meter identification, real-time data acquisition, operators do not have to meter reading." Chen Dekai said, patrol robots can also take infrared photos, timely detection of whether the device is hot, timely tracking equipment Status, equipment control and full life cycle management.
Use robots to save labor costs
With the continuous development of the power grid, the number of new substations will increase, and daily inspections will occupy a large amount of human resources. With patrol robots, they can work 24 hours a day, complete daily inspections, special inspections, fault inspections, and job inspections, which greatly increase the efficiency of inspections.
Taking the 500-kilovolt grass-paved substation as an example, there are nearly 400 pieces of total station detection meters and more than 600 temperature measurement points. If a total of four people are patrolled by the two groups, it will take about 3 days to fully inspect the grass-paved substation once. If robotic inspections are used, only two individuals are required to complete the on-site inspection of the grass shop substation.
By 2020, the Kunming Power Supply Bureau is expected to have more than 200 substations. If full coverage of patrolling robots is achieved, each substation will save at least 2 people each day, be able to release a large amount of human resources, and effectively invest in the management of key operations sites. Reduce the incidence of accidents caused by insufficient human resources during job management.
At the same time, the patrol robot system also has data analysis and learning capabilities. “The Kunming Power Supply Bureau is working with robot manufacturers to develop a robotic intelligent analysis platform. Afterwards, a computer and a terminal can now realize the control and data investigation of all robots in the world, and the intelligent analysis platform can intelligently analyze the data and comprehensively view the equipment. The "healthy situation" facilitates the formulation of equipment maintenance and maintenance strategies so that the equipment can better serve the power grid, said Chen Dekai.
P2.2X3 Automotive Right Angle Male Connector
P2.2X3 Automotive Right Angle Male Connector.Automobile connector is a kind of component that electronic engineers and technicians often contact. Its function is very simple: build a communication bridge between blocked or isolated circuits in the circuit, so as to make the current flow and realize the predetermined function of the circuit. The form and structure of automobile connector are ever-changing. It is mainly composed of four basic structural components: contact, shell (depending on the variety), insulator and accessories.
