Embodiment Construction

[0038] The invention will be illustrated below with the aid of the above-mentioned drawings, this illustration is not a limiting example. For convenience, they are appropriately labeled with appropriate reference numerals.

[0039] The vertically moving automatic return guide 1 has a follower pin 2 fastened thereto. Said device 1 has a guide 3 , which limits its movement on a transmission 5 . Restricted movement is achieved by a stop 7 provided on the transmission 5 , positioned so that said device 1 stops moving when it comes into contact with either end of the guide 3 .

[0040] Such as Figure 1b As shown, the vertically moving automatic return guide device 1 is loaded on the drive mechanism 5 by the spring 4, and when the circuit breaker 10 has not been loaded into the bracket 11, the device remains in the raised position, and when the device is lifted or lowered The device does not interfere when the circuit breaker is raised or lowered by the trolley 12 to be loaded i...

Abstract

A new guide rail transmission mechanism for a pull-out circuit breaker, the mechanism includes: a vertically movable automatic return guide device, the device has a guide for restricted activities and a follower fastened thereon movable pin; for its self-returning feature the device is spring loaded onto the mechanism for moving or driving the circuit breaker into the carriage, and the device is positioned on the mechanism so that when the circuit breaker is not When placed in the bracket, the device maintains its normal, raised position, while when the circuit breaker assembly guide is placed into the slot provided on the mechanism for the assembly guide, one of said assembly guides on both sides of the circuit breaker stops on a respective vertically movable self-return guide, thereby pushing said device downward; When disengaged in the bracket, the device returns to its raised position; the rail drive mechanism is so designed as to ensure that the vertically movable self-return guide never extends under the body of the circuit breaker.

Description

technical field [0001] The invention relates to a guide rail transmission mechanism in a pull-out circuit breaker. The object of the present invention is to easily load and unload circuit breakers into and out of their bays using a standard trolley having a vertically mobile platform in addition to other loading and unloading common tools. Background technique [0002] In a drawer circuit breaker, the circuit breaker is placed in a bracket which in turn is connected to the mains by cables, links or any other means. Generally, a pull-out circuit breaker can be in the following four positions relative to its bracket: (1) maintenance position, that is, when the circuit breaker can be withdrawn from the bracket or loaded into the bracket; (2) insulation position , that is, when it is completely disconnected from power and control power but it is still firmly engaged on the bracket; (3) the test position, that is, when it is in the bracket and connected to the control power (whi...
