| 摘 要： | 以电起爆和检测的安全问题论述了电雷管的电磁感应起爆系统,即MBS(Electro-Magnetic Induction Blastins System)系统。该系统的基础理论是法拉第电磁感应原理,并结合利用软磁锰锌铁氧体频率传输特性的原理。它的引爆是由专用起爆器向相应爆破母线(锰锌铁氧体磁芯线圈)传送特定的高频波电流,在以电磁联接的变换器(锰锌铁氧体磁芯)的相当于电雷管脚线的二次线圈中感应出能使电雷管引爆的电流。论述了多种类型和结构的MBS系统,并就其特点及对电的安全性确定了最安全的电磁感应起爆系统,同时论述了专用起爆器和多种国内外领先的电磁感应安全检测仪的开发应用。

| Abstract: | This paper describes the Electro-Magnetic Induction Initiating System regarding the safety of electric blasting and measurement. This system is called MBS (Electro-Magnetic Induction Blasting System), which is based on Faraday Electro-Magnetic Induction Principle together with the frequency transmitting feature of the soft Mn-Zn ferrite as shown in Fig.1. Its initiating principle is that when a high frequency current from a special exploder is supplied to the bus wire, i.e., the primary coil of the ferrite core, a current which can fire a detonator is induced in the detonator legwires, i.e., the secondary coil of the ferrite. The paper describes a number of MBS types with various design and determines the most safe one according to their features and electric safety. Furthermore, it describes the development and application of special exploders and various advanced testing instruments. |
