Embodiment Construction

[0022] figure 1 An arrangement of a plurality of short-circuit devices 1 , 2 , . . . 5 connected in parallel is shown. Each of these short-circuit devices has a moving contact and a stationary contact. The parallel connection leads overall to a high-current form, or a form with a high effective current-carrying capacity. Here, the respective movable contact is driven in each case by the advancing charge. The advancing charge of all parallel-connected short-circuit devices is controlled synchronously in time by means of a common ignition device.

[0023] on the contrary, figure 2 Indicates a series circuit of short-circuiting devices. This results in a high pressure form. In this form, the voltage is divided. Although a common ignition device is also provided here for voltage isolation, only one of the short-circuit devices can be directly controlled, i.e. the initiator / propellant charge of one of the short-circuit devices, while the control of the initiator / propellant c...

Abstract

The invention relates to a switch arrangement for medium and high-voltage switching devices having switches (12), with which at least one of the contacts is a moving contact which can be actuated by means of a propelling charge. In order to ensure that both a high-current arrangement and a high- voltage arrangement can be taken into account, according to the invention it is proposed that, for a plurality of switches, a dedicated propelling charge is provided for each switch, and that the propelling charges are coupled together with regard to the time of the ignition.

Description

technical field [0001] The invention relates to a switchgear according to the preamble of patent claim 1 for medium-voltage and high-voltage switching devices having switches in which at least one of the contacts is chargeable by means of ignition Actuated moving contacts. Background technique [0002] A short-circuit device has already been disclosed in DE 10254497 B3, in which a push charge is provided for moving the movable contact. In this way an effective and mechanically very fast contact closure can be achieved. [0003] However, high voltage and high current situations must be considered separately. Contents of the invention [0004] Therefore, the present invention is based on the object of further developing such a switchgear to the effect that both high-current devices and high-voltage devices can be taken into account. [0005] The object of the invention is achieved according to the invention by the particular features of claim 1 . [0006] Further advanta...
