摘要

In the operation of large turbine generator sets, hydrogen is often used as a cooling medium to take away heat and maintain the normal operation of the set. However, hydrogen is easy to leak and not easy to be found, so it is necessary to measure the leaked hydrogen in real time. In order to ensure the explosion-proof performance and personal and property safety of hydrogen detection equipment, the design of an intrinsically safe switching power supply circuit for hydrogen leakage detection system to improve the explosion-proof performance of the equipment will be extremely important in both scientific research and commercial applications. Meaning. The author will explain the intrinsic safety technology background and development process, intrinsic explosion-proof technology and intrinsically safe power supply design.
