Embodiment Construction

[0029] Note that anything found to be known during the patent process is understood to be the subject of no claim and disclaimer.

[0030] Referring to the drawings, reference numeral 10 generally designates a semi-boom breaker, which includes:

[0031] base 11, which supports the motor movement system 12,

[0032] An arm 13 , which at a first end 13 a has a bearing plate 14 for clamping a boom 15 , is hinged at a second end 13 b to a base 11 so that it can swing about an axis A of rotation.

[0033] In this way, by rotation about the axis of rotation A by actuation of the motor-kinematic system 12, the arm 13 can be reversibly transferred from the off configuration to the contact configuration, in which the arm 13 falls onto the base 11, and in the contact configuration In this case, the arm 13 diverges from the base 11 through the electrical contact between the carrier plate 14 and the boom 15 .

[0034] According to the invention, the disconnector 10 is characterized in t...

Abstract

A semi-pantograph disconnector, comprising - a base (11), which supports a motor kinematic system (12), - an arm (13), which has a shoe (14) for gripping a dropper (15) and is hinged to the base (11) so as to be able to oscillate in order to pass reversibly from a disconnection configuration, in which the arm (13) is collapsed onto the base (11), to a contact configuration, in which the arm (13) is divaricated from the base (11) so as to connect by means of the shoe (14) to the dropper (15), - a rod (16), which is functionally connected to the shoe (14) in order to actuate it, - a cam device (17) for actuating the rod (16), which coordinates kinematically the opening of the shoe (14) and a first rotation of the arm (13) from the disconnection configuration to the contact configuration, - a semi-pantograph device (18), which is functionally connected to the rod (16), to the arm (13) and to the motor kinematic system (12), defining a kinematic sequence for closing the shoe (14), after the first rotation of the arm (13), and a kinematic sequence for opening the shoe (14), which is preliminary to a second rotation of the arm (13) which moves it from the contact configuration to the disconnection configuration.

Description

technical field [0001] The invention relates to a semi-moving arm type disconnector. Background technique [0002] Several models of boom or semi-boom disconnects are currently known. [0003] In particular, so-called vertical-break disconnects of the boom or semi-boom type are known. [0004] In the former, the contact force is linked to the elasticity of the material and thus to the rigidity of the active component tube, and in order to have a high contact force it is necessary to have a high operating torque. [0005] In semi-booms, instead, a spring-operated device ensures a high contact force. The additional spring allows to have a low operating torque as it balances the closing action of the disconnect. [0006] Disconnectors with rocker arms are also known, which have an arm which rotates on command during closing, with the shoe straddling the dropper to provide it with the desired electrical contact, and The carrier plate is then closed to ensure the durable func...
