GAS CIRCUIT BREAKER OF RESISTANCE BREAKING TYPE |
摘要 |
<p>Disclosed is a gas circuit breaker of resistance breaking type, which comprises a main breaking unit and a resistance contact mechanism electrically connected in parallel with the main breaking unit for resistively cutting off current. With the opening action of the main breaking unit, a spring used for opening the resistance contact mechanism is energized and the energized force of the spring is released by a releasing mechanism after the current in the main breaking unit is cut off, thereby to act as a drive force to open the resistance contact means.</p> |
