Abstract
The invention relates to a medium voltage switchgear having disconnecting switches and three-position switches, according to the preamble of claim 1. In order to more easily make different implementations of the current-carrying capacity, according to the invention, the attainable current-carrying capacity is increased with respect to a base current-carrying capacity by means of the multiple arrangement of identical contact systems (1) per phase (L1, L2, L3) in a parallel arrangement on a common switch axis (2).
Description
The present invention relates to a kind of medium-voltage switchgear of the preamble according to claim 1 with disconnect and three-position switch.
Be that two kinds of typical current capacities are provided with disconnect and three-position switch in medium-voltage switchgear.A kind of common standard compliant value according to IEC is that 1250 amperes and another value are 2500 amperes.Therefore the different component that also needs said switch for different current capacities.
This different design has the shortcoming of manufacturing process.
Therefore task of the present invention is, following similar medium-voltage switchgear, the feasible different switching that can realize current capacity more simply further improved.
Said task is the characteristic of part solution according to the invention through the features of claim 1 in similar medium-voltage switchgear.
Other favourable scheme provides in the dependent claims.
Core of the present invention is, through going up layout with parallel connection at a common switch shaft (2) to identical each contact system (1) of the multiple layout of each phase (L1, L2, L3), accessible current capacity improves with respect to basic current capacity.Therefore now contact member can all be made uniformly, thus be only parallelly connectedly each contact system of arranging mutually in other words the quantity of switch structurally improve the current capacity of corresponding hope.
In the scheme favourable to this, set, basic current capacity is 1250 amperes, and the contact pin of disconnect and/or three-position switch is to this current capacity design.
In another favourable scheme, set, 2500 amperes current capacity realizes that through on a switch shaft, two contact structures are laid layout parallelly connectedly the basic current capacity of said two contact structures is respectively to 1250 amperes of designs.
In another favourable scheme, set, switch shaft is made up of plastics.Obtain the simply insulation to each other of each contact structure thus, all three contacts that exchange phase can be placed on the switch shaft like this.
Replace, switch shaft also can be made up of ceramic material.
For guaranteeing high mechanical torsional strength, be provided with in an advantageous manner, in switch shaft integrated machinery reverse locking element or rotation locking element, switch shaft itself passes through that it is mechanically antitorque.
Another favourable structure alternative is characterised in that switch shaft is made up of metal, and joystick disconnect or three-position switch is made up of plastics.
Be described in the drawings and then specify the present invention.
Fig. 2 illustrates three contact members or the layout of contact structure 1 on a switch shaft, and they are used for all three interchange phase L1, L2 and L3.At this, each exchanges a contact structure is set respectively mutually.
Fig. 1 illustrates, and each phase place is provided with the contact structure 1 of two parallel connections respectively on axle or switch shaft 2.For functional understanding, point out that once more said axle makes control lever movement, said joystick then itself is made the contact motion again.In the description of Fig. 2, each contact structure, be that each is equipped with mutually 1250 amperes current capacity.Therefore realize total current capacity of 2500 amperes through the dual structure among Fig. 1.
Therefore the multiple layout of the contact structure through each phase can for example realize many times of the integers of basic current capacity.But also can the different contact structure of application structure, each single current capacity capable of being combined produces any total current capacity of each phase jointly from these contact structures.
Such 1250 amperes switching device can be processed through the contact structure of producing in batches in advance as for example 2500 amperes switching device.This only the doubling and on same switch shaft, realizing of the contact structure through each phase.
