Abstract

The invention discloses a mine intelligent permanent magnet vacuum circuit breaker, which comprises an intelligent permanent magnet vacuum circuit breaker, an upper computer, a driving board, an ARM interface and a photoelectric signal, and is characterized in that the intelligent permanent magnet vacuum circuit breaker comprises a digital signal processor (DSP) chip, an ARM processor chip, a PLC and an ARM interface, the input end of the intelligent permanent magnet vacuum circuit breaker is electrically connected with the output end of the digital signal processor (DSP) chip, and the input end of the intelligent permanent magnet vacuum circuit breaker is electrically connected with the output end of the ARM processor chip. According to the permanent magnet vacuum circuit breaker, intelligent components and reliable elements are adopted, and the permanent magnet vacuum circuit breaker has an online monitoring technology and an intelligent operation technology through a network communication technology, so that the breaking capacity and the service life of the intelligent circuit breaker are improved, and the overvoltage in the underground coal mine power gridand the interference of power grid harmonic waves are well inhibited so as to greatly improve the reliability and the service life of the circuit breaker and improve the breaking capacity of the circuit breaker.

Description

technical field [0001] The invention relates to the field of remote operation and maintenance systems for textile machinery, in particular to an intelligent permanent magnet vacuum circuit breaker for mines. Background technique [0002] The intelligent control of permanent magnet vacuum circuit breaker refers to the effective combination of microcomputer technology and circuit breaker control, which has stronger and more flexible logical judgment and analysis capabilities. It is related to the coil parameters, and it is possible and easy to control the electrical parameters at the same time. Therefore, the opening and closing characteristics of the permanent magnet mechanism can be controlled by the microcomputer system, so that the intelligent control of the vacuum circuit breaker can be realized, and the moving position of the moving iron core and the coil can be detected. Current, instantaneous power-on time and other parameters, and can realize the self-test function, a...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, with the application of microelectronics technology in coal mine underground electrical equipment, mine electrical equipment began to have functions such as self-diagnosis and fault memory, which greatly improved the automation of mine electrical equipment, but there are still The shortcomings of low intelligence and weak communication ability, this intelligent circuit breaker is to solve the defects of current circuit breakers, and various physical quantities such as electricity, light, heat, magnetism, displacement, speed, vibration, discharge, etc. The sensor collects and processes the above signals. For this reason, we propose mine intelligent permanent magnet vacuum circuit breaker
