Abstract

The invention relates to the technical field of electric smelting furnaces, in particular to an electric parameter online measuring system of an electric smelting furnace. The online measuring systemcomprises a computer monitoring system, CAN buses and three groups of electric parameter measuring circuit boards, wherein the three groups of electric parameter measuring circuit boards are all connected with the computer monitoring system by the CAN buses; each of the electric parameter measuring circuit boards comprises an MCU, an alternating current signal conversion module, an alternating current signal acquisition and processing module, a temperature control module and a watchdog; each of the alternating current signal conversion modules is connected with the corresponding MCU by the corresponding alternating current signal acquisition and processing module; each of the temperature control modules and the corresponding watchdog are connected with the corresponding MCU. The online measuring system has the beneficial effects that a communication network is established by using the serial communication CAN buses, so that the requirements of timeliness, remote communication and expansibility can be met; in addition, the cost can be effectively lowered, and the development time is shortened; computer monitoring software is designed by adopting a Labwindows/CVI as a software development tool, and a software design method in a multiple-thread architecture is adopted, so that the response speed of the online measuring system is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of electric smelting furnaces, in particular to an online measurement system for electrical parameters of electric smelting furnaces. Background technique [0002] Generally, the electric smelting furnaces used in the metallurgical industry are large energy-consuming devices. Some steel-making electric arc furnaces have a capacity of up to 5000kVA and an alternating current of more than 2000A. Strong AC current, severe electromagnetic interference, complicated secondary wiring network, and harsh high temperature environment have brought great difficulties to the accurate measurement of electric furnace electrical parameters, making it a major problem that the power industry has been conquering. This subject is mainly focused on the measurement of electrical parameters of electric smelting furnaces. The entry points of the research include: design of large current measurement schemes and determination of electrica...
