TH1505EX - Electrode contact protection for closed switch cabinet - Google Patents

Abstract

Electrode contact protection for closed switch cabinet (ES) castor mounted circuit breakers (1) are composed of an upper protective sheet and a lower protective sheet (24A, 24B). End (2 A '') on the side facing The circuit breaker is mounted on the castors of the upper harness (2 A) (placed on top of the grounded partition) to the power supply bus (4), and the lower shield will Close the tip (2B '') on the side facing the circuit breaker mounted on the Guide wheel of lower cable guide insulator (2B) (placed at the bottom of Earthed barrier) to prevent personnel from touching With the casing, leading the cable after playing the circuit breaker Wheel-mounted type exits from closed switch cabinet When the castor-mounted circuit breaker is slid into the switch cabinet, the upper protective cover plate (24A) rotates to close the end. That facing the wheel-mounted circuit breaker of Insulating sleeve, upper set cable The lower shield (24B) is rotated down from the end of the lower shield and the distribution bus opens the end. On the side facing the wheel-mounted circuit breaker Sliding of the lower cable guide insulator
