变频器外部输入控制端子在实践教学中的安全保护措施

Security Protection Measures of External Input Control Terminals of Inverters in Practical Teaching

变频器的安全是确保变频技术课程实践教学顺利完成的保障,也是直接影响到教学效果的因素之一本文介绍保护变频器安全的保护措施,设计一个可靠的保护电路,确保变频器完好无损,在最短的时间内重新投入实践教学,将对教学进度的影响减至最小,同时也控制了教学成本。

The safety of inverters ensures the practical teaching of the inverter technology goes smoothly.It is also one of the factors affecting teaching effects directly.This paper introduces the protection measures to protect the safety of the inverters,designing a reliable protection circuit,to ensure the inverters intact.They can come into use again in a short time,minimizing the impacts on the schedule of teaching,and controlling the teaching costs.
