Optimized Design of DCZB Series Intelligent Protector for Underground Explosion-proof Switches

This paper delves into the current utilization status of intelligent protectors for explosion-proof switches in Chinese coal mines. It specifically addresses issues such as substantial voltage fluctuations and insufficient short-circuit protection. Drawing upon the principles of safety ergonomics, a comprehensive design approach has been adopted for the explosion-proof switch, encompassing both hardware and software enhancements to mitigate the challenge of short-circuit tripping. In the realm of hardware design, the integration of 2.4GHz wireless communication technology for temperature monitoring and tripping protection has been instrumental. Additionally, the implementation of a delayed rebound system serves to meticulously record and diminish false operational triggers. On the software front, beyond fundamental protection functionalities, the strategic use of wireless technology effectively resolves power transition concerns, thereby augmenting operational efficacy. This innovative solution exhibits substantial promise in enhancing the safety and operational efficiency of electrical equipment within coal mines. It stands poised to play a pivotal role in revolutionizing coalmine production practices.
