Industry Background

In recent years, driven by dual factors of national policy guidance and technological innovation, the lithium battery industry has maintained rapid growth, with the scale of the industry continuously expanding. At the same time, the power-intensive production lines of new energy industry factories are highly dependent on electricity, thus placing high demands on the reliability of power supply equipment. As an essential power transmission device for factory floor electrical distribution, when poor contact at the busbars due to factors such as manufacturing, transportation, and installation issues leads to increased contact resistance, excessive temperature rise in the contacts, and even power outages or fires, it greatly impacts the safety of factory production lines and the economic benefits of the enterprise.

However, it appears that for the operation and maintenance of dense busbars, the traditional approach is for maintenance personnel to conduct monthly inspections. This involves using handheld infrared thermometers to randomly check the connections of the busbars. This method is highly inefficient, significantly increasing the workload for maintenance staff. Moreover, high-voltage busbar equipment is typically installed at several meters in height, in confined and narrow spaces, making it often impossible to conduct manual inspections and temperature measurements. The traditional temperature measurement methods are unable to effectively address these issues and pose significant safety risks.

Therefore, the busbar slot temperature monitoring system has emerged. This system can reliably predict early fault defects in dense busbar slots, and by utilizing various algorithms and logic, it can proactively resolve overheating issues. It elevates preventive maintenance to predictive maintenance, reducing the frequency of power outages, and enhancing the reliability of busbar slot power supply.

AnkoRi'sAMB300 series busbar槽infrared temperature measurement solution is a non-contact infrared temperature sensor designed to address the issue of excessive temperature rise in busbars. It uploads real-time temperature data of each phase within the connector to the back-end, alerting managers to pay attention to or take necessary precautions at alarm points.

Project Overview

The lithium battery factory project is located in Guangdong Province, covering an area of approximately 130,000 square meters with a total floor area of over 300,000 square meters. It is planned to include 2 office and R&D buildings, 7 factory buildings, and 3 dormitory buildings. The main construction includes the establishment of a production line for 180 million digital product polymer lithium-ion batteries and a production line for 180 million wireless Bluetooth earphone lithium-ion batteries. The project's energy consumption and efficiency indicators: after the project is completed and put into operation, the annual comprehensive energy consumption will not exceed 33,140 tons of standard coal (equivalent value), with an annual electricity consumption of no more than 17,066 million kilowatt-hours and a natural gas consumption of no more than 9.9 million cubic meters. The comprehensive energy consumption per unit product will not exceed 306.85 kilograms of standard coal per 10,000 ampere-hours.

The project features over two hundred temperature sensing points, utilizing our company's AMB300 series busbar tray infrared temperature measurement solution. This is a non-contact infrared temperature measurement device, which addresses the issues of safe and accurate busbar tray temperature measurement. It uploads real-time temperature data of each phase in the connectors to the backend, implementing monitoring and early warning information, alerting management to pay attention to or take necessary preventive measures at alarm points.
