Industry background

With the development of today's society and the sharp increase in electricity consumption, as well as the emergence of modern engineering facilities and equipment, enclosed busbars, also known as bus ducts, have gradually replaced traditional cables due to their convenience, energy saving, high current carrying capacity, high mechanical strength, flexible installation, and long service life. They are widely used in indoor transformer stations, high-rise buildings, and large factories and workshops. The busbar trunking adopts a copper bar compression method, which requires high heat dissipation and insulation performance. However, during long-term operation, due to excessive load or the influence of air oxidation, dust and other factors, the temperature at the connection of the busbar trunking increases, accelerating the aging of the outer insulation, causing power failures, disrupting the stability of the power grid operation, and seriously causing fire accidents. Therefore, installing a busbar trunking temperature measurement system is of great significance for preventing safety accidents and ensuring the reliable operation of the busbar trunking.

Project Overview

A breeding project in Nansha is located in Nansha District, Guangzhou City, Guangdong Province. It is currently a high rise pigsty in Guangdong Province, with a land area of 140 acres, a pigsty building and supporting land of 110 acres, an investment of 1.6 billion yuan, and an annual output of up to 350000 pigs. The project will build a modern breeding demonstration base for feed processing, pig farming, food processing, and environmental protection treatment, integrating feed processing, slaughtering, and commercial operations.

This project has a total of 16 bus ducts and 887 bus connectors. Our AMB300 series bus duct infrared temperature measurement solution is applied, which is a non-contact infrared temperature measurement device. The system can solve the safety temperature measurement and temperature measurement problems of bus ducts. The real-time temperature data of each phase in the connectors is uploaded to the background for monitoring and warning information, prompting management personnel to pay attention to alarm points or take necessary preventive measures.

Implementation Plan

3.1 Application Plan

This bus duct infrared temperature measurement solution consists of a human-machine HMI touch screen, an infrared temperature measurement module, an infrared collector, and a power module. The system communicates with the local touch screen through RS485 cable, and then uploads data from the touch screen to a third-party platform (as shown in the figure below). The system design follows the Modbus RTU transmission protocol, and its security, reliability, and openness have been greatly improved. RS-485, as a serial communication interface, has the characteristics of long transmission distance, high speed, good level compatibility, flexible and convenient use, low cost, and high reliability. Compared with wireless communication methods, it has the advantages of low price and strong resistance to common mode interference.
