PUFFER TYPE CURRENT INTERRUPTER

摘要

The interruptor employs a pair of symmetric electrodes (36, 37) with contact bosses (36a, 37a) provided on their confronting surfaces. An insulator nozzle (35) is arranged such that the throat section for providing a jet of arc blasting gas is located in the periphery of the bosses (36a, 37a). The electrode structure provides a uniform electric field between the electrodes (36, 37), thereby gaining the breakdown voltage.
