Embodiment Construction

[0028] To illustrate the invention, the vertical, longitudinal and transverse directions defined with the reference system V, L, T as indicated in the figures are used.

[0029] figure 1 Shown is a part of a control device 10 of an electrical switching device, for example a circuit breaker for a high-voltage or very high-voltage transmission line.

[0030] The control device 10 includes a frame 12, which in this example consists of a pair of parallel plates 14 spaced laterally from each other.

[0031] In particular, each plate has two flaps 15s, 15i extending substantially longitudinally and vertically offset from each other.

[0032] A magnetic core 18 is mounted between the two plates 14 .

[0033] The magnetic core 18 is manufactured in two parts, a first part 24 is fixed to the bracket 12 by means of two bolts 20, 22 clamped between the two plates 14, and the other part 26 is fixed to the bracket in a detachable manner. 12 on.

[0034] The detachable part 26 is first ...

Abstract

The invention relates to a device (50) for locking medium-voltage or high-voltage electrical equipment, comprising a pivotable ratchet (36) and a device (40, 42) for locking said ratchet (36), characterized in that , the device (50) can be detachably mounted on the device, and the device (50) can lock the ratchet (36) and the locking device (40, when mounted on the device, 42).

Description

technical field [0001] The invention relates to a locking device for locking an electrical switching device, said device being designed to prevent movement of parts of the switching device. [0002] The present invention more particularly relates to a locking device adapted to be removably mounted on electrical switching apparatus. Background technique [0003] In electrical switching apparatus for medium or high voltage power lines, such as power line circuit breakers, the movable part for opening or closing the power line is driven by a control device. [0004] Such a control device comprises in particular a ratchet mechanically connected to the movable part and mounted to move in the control device between a rest position corresponding to the closed position of the circuit breaker and an activated position corresponding to the open state of the circuit breaker . [0005] When the operator is going to work on the circuit breaker, the control device must be locked in the ...
