Interrupting chamber with a field distributor cylinder for high-voltage or medium-voltage circuit breakers
摘要：
An insulating tube (18) located between the main contacts (12b, 14b) and the arcing contacts (12a, 14a) of an interrupting chamber (10) of a high-voltage or medium-voltage circuit-breaker makes it possible to modify the distribution of the equipotential lines (V) during breaking. Thus, it is possible to reduce the electric field on the contacts, and thus to improve the breaking and the dielectric strength in the open position. The insulating tube (18) can also serve for transmitting movement between the contacts (12, 14) for triggering the circuit-breaker.
摘要（中）：

位于主触头（12b，14b）和高压或中压断路器的中断室（10）的电弧触点（12a，14a）之间的绝缘管（18）使得可以修改 断路期间等电位线（V）的分布。 因此，可以减小触点上的电场，从而提高打开位置的断裂和介电强度。 绝缘管（18）还可以用于在用于触发断路器的触头（12,14）之间传输运动。
