Abstract:To measure the interruption characteristic of low voltage molded case circuit breakers(MCCB) more precisely, a set of novel 2-D optical fiber system is developed. The obsrever behavioral design pattern is applied to the software and the loosely coupled relationship between glyph and experimental data is once established, the graphic configuration can be implemented for simulation analysis, and the flexibility and applicability of the whole system are obviously improved. To avoid the error derived from the overlap among the neighboring optical fibers, lens with inhomogeneous dielectric is fixed on the top of each fiber. Furthermore, the full hardware control logic facilitates the real time, synchronous and high speed processing and breaks through the restricted bus operation frequency range and data stream capacity in a microprocessor. It demonstrates that the system provides a better research technique especially for new generation MCCB with gas driven arc.
