The robot "Big White" in the movie "Big Hero 6" is warm and healing, and has captured the hearts of thousands of girls, and in the Southern Power Grid Guangdong Zhongshan Power Supply Bureau Daxin Phase II public switching station, there is also a robot "Big white", with its guardian, the distribution power plant equipment can maintain a healthy state every day, from now on, the power supply people do not have to busy running the major distribution rooms in the wind and rain. Remote inspection can be done in the office. Recently, the first distribution network inspection robot of Southern Power Grid was put into operation in Shiqi Daxin power room of Zhongshan Power Supply Bureau of Guangdong Power Grid.





The power behind the soft cuteness

White fat body, round big head, and then matched with black big eyes, stupid cute appearance and "Big White" in "Super Power Marine Corps" exactly the same, Nakama Shiqi Branch people call it "big white".

"The inspection robot of the distribution room is not only cute in appearance, but also has a particularly high inspection efficiency, which can meet the requirements of regular inspection," said Hong Xiaodi, director of the distribution department of Shiqi Branch. Into the Zhongshan Daxin phase II public switch station, the clean power room looks ordinary, but it is the first intelligent switch station based on IEC61850 protocol, full circuit breaker type, full optical fiber communication, which can achieve millisecond level restoration. Recently, the ceiling of this electricity room has been paved with a neat guide rail, which is the fixed line inspected by the robot "Baymax" every day. Its sports chassis can glide smoothly along the guide rail at a speed of up to 30 meters per minute, and it has a neck that can reach a length of 1.6 meters. The "big white" head, that is, its host, is equipped with a variety of high-specification sensors, conventional infrared thermal imaging temperature detection system, industrial camera vision system, visible light video surveillance system, special is that it also has a highly sensitive ultrasonic detection system, transient ground wave TEV detection and noise, temperature and humidity, gas sensors, etc. It is like a medical doctor, can carry out a comprehensive "physical examination" of the equipment at any time.

Intelligent inspection shows its skill

"Today, the volume of equipment under our jurisdiction is growing rapidly, and manual inspection is difficult to meet the cycle requirements. Now we use intelligent equipment for comprehensive inspection of the distribution power station equipment to meet the unattended requirements of the intelligent distribution power station, "said Liu Jianchu, senior specialist in distribution network management of Zhongshan Bureau.

"Big White" vision system can imitate the human eye inspection tour, or even stronger, the accuracy of instrument identification is greater than 95%, and can carry out rapid and instant intelligent analysis and early warning of equipment. "We all thought it was amazing that it could do local discharge tests all by itself." Shiqi branch distribution operation and maintenance team member Li Meilin praised. In the past, the routine inspection of a total of 20 cabinets in the electricity room required two staff members to spend about half an hour, and the office release test for each cabinet required 3-5 working days. Today, "Baibai" can capture ground waves and ultrasound through two arms, collect and record signals in real time and transmit them, complete the local discharge test alone, and truly achieve remote control, and the entire sampling time is not more than 20 milliseconds! It can also directly shoot the electricity volume, switch status, and control the humidity and temperature of the power room. In addition, "Big white" also has thermal imaging temperature detection, 1080P full HD video surveillance, smoke, temperature, humidity and ozone detection ability, so that people can grasp the status of the power station in real time without leaving the house.

With "big white", is a set of intelligent distribution room comprehensive online monitoring system, Shiqi Branch distribution operation and maintenance shift every day as long as the monitoring system in the computer, you can see the distribution room online monitoring display, including comprehensive environment, comprehensive electrical, equipment status monitoring. The system can also integrate distribution line online monitoring, distribution network automation, metering automation monitoring data, to set the early warning model, including environmental alarm configuration, electrical alarm configuration, equipment alarm configuration, security alarm configuration, and then automatically according to the status early warning Settings in real time.

It is reported that at present, "big white" is the first intelligent inspection robot used in the distribution network of Southern Power grid, its application effectively improves the efficiency of inspection, can vigorously solve the wide range of distribution network, equipment, manpower shortage and other problems, and will further strengthen the promotion and application in the distribution network in the future.
