Title:
LOW-VOLTAGE CIRCUIT-BREAKER WITH A RETROFITTED POWER-DRIVEN LIFT
Document Type and Number:
WIPO Patent Application WO2000003405
Kind Code:
A3
Abstract:
The invention relates to a low-voltage circuit breaker with a retrofitted power-driven lift, whereby the output shaft thereof can be coupled to the charging shaft of the spring energy store of the low-voltage circuit breaker and said charging shaft is mounted in a bearing block. Centering elements (9) are provided on one flange of the bearing block (11) of the charging shaft (12) of the spring energy store and engage with counter elements (10) on the output side of the gear of the power-driven elevator (5) in such a way that the lift can extend axially with only a limited amount of travel in the direction of the charging shaft (12). In order to arrest the power-driven lift (5) in a pivoting direction, a fixing element is provided at a point located at a certain distance from the centre, in addition to means enabling the power-driven lift (5) to be fixed in an axial position in the centering elements (9) of the flange of the bearing block (11) of the charging shaft (12) of the lift of the spring and in the coupling (8) of the charging shaft (12).
