Problems solved by technology

However, according to the prior art, although it is possible to have so-called quick closing and delayed opening characteristics, there is a problem that due to the disconnection between the fixed contactor and the movable contactor in the neutral pole at the time of opening, The opening distance (i.e., the insulation distance) is shorter than that of the other poles, so electrical isolation of the neutral pole cannot be ensured

Abstract

Provided herein is a power transmission mechanism for a four poles circuit breaker in which the contacts of a neutral pole thereof are brought into contact earlier at the time of closing and separated later at the time of opening than those of the other poles thereof, and according to the present invention, there is disclosed a power transmission mechanism for a four poles circuit breaker comprising: a switching shaft (12) configured to provide a driving force for switching to the movable contactors of the poles; an arm (13a, 13b, 13c, 13d) provided to correspond to the four poles to transfer the rotational torque of the switching shaft; and a link (14b, 14d) configured to transfer the rotational torque of the arm to the movable contactor as a switching force, and provided to correspond to the four poles, wherein the sum of the length of the arm and the link in a neutral pole is longer than the sum of the length of the arm and the link in the poles excluding the neutral pole.

Description

technical field [0001] The present invention relates to a four-pole circuit breaker, and more particularly to a power transmission mechanism for a four-pole circuit breaker. Background technique [0002] A four-pole circuit breaker (that is, a three-phase four-wire type circuit breaker) has a configuration that includes four movable contactors and fixed contactors respectively corresponding to four poles to simultaneously switch three-phase AC power lines and neutral The neutral line, the three-phase AC transmission line has R pole (that is, R phase), S pole (that is, S phase) and T pole (that is, T phase), and the neutral line has a grounded neutral pole (N pole or that is N phase). Here, the neutral line is a line that plays an important role in safely supplying electric power. This is because various relays for detecting abnormal current caused by ground fault current, short circuit current, lightning, etc. are connected and installed to the neutral line, and multiple g...
