Abstract
A 3-position switch drive for supply swith device has operating elements (BE) and switch position display devices (SA) positioned at the front side (AS) of the drive, arranged immediately adjacent to one another for fault-free operation of the switch functions. Signal switch contacts are provided by separate terminal plugs (AE) especially fitted switch function, with the drive couplings (AK) for the primary contacts associated with a common interface point (SK) and accessible from the front side (AS) of the drive. The 3-position switch drive is particular suitable for air-insulated medium-voltage switchgears.
Description
Technical field
The present invention relates to that a kind of power supply and distribution switchgear use, especially the three-position type driving mechanism for switch used of gas-insulated medium voltage switchgear equipment, the signaling switch contact that it has executive component and position of the switch indicating device and is connected by cable connecting arrangement, and have can be from the transmission coupler of the approaching main contact in three-position type driving mechanism for switch back.
Background technology
The three-position type driving mechanism for switch of the above-mentioned type is known by the file of Siemens AG Representation " pattern 8DC11, catalogue HA 35.41, August nineteen ninety-five for the power switch fixed installation equipment that 24KV is following, SF6 insulation ".By the 7th page of file distribution board structure as can be known, " opening circuit " function of three-position type switch and " ground connection " function operations of three-position type switch are directly arranged side by side, and relevant with it position of the switch indicating device does not spatially get up to be provided with these functional cohesions.
In addition, by the 8th page of this document as can be known, transmission coupler and main contact engage and thereby the passage that is used to adjust the drive unit movement relation be in the back of drive unit cabinet.Therefore need be engaged in a large amount of assembly works for the movement relation of setting and adjust drive unit.
Summary of the invention
The object of the present invention is to provide a kind of three-position type driving mechanism for switch, it allows generally is a kind of comfortable mode of operation, and has especially got rid of the danger of obscuring substantially when the manipulation operations part.
According to the present invention, this purpose is used by a kind of confession, distribution switchgear, especially the three-position type driving mechanism for switch used of gas-insulated medium voltage switchgear equipment is realized, the signaling switch contact that this device has operating parts and switch indicator and is connected by cable connecting arrangement, and have can be from the transmission coupler of the approaching main contact of three-position type driving mechanism for switch rear side, wherein
1.1 this operating parts and position of the switch indicating device are arranged in the drive unit region in front in such a way,, by configuration adjacent to each other spatially, reach console switch function inerrably that is,
1.2 this signaling switch contact is introduced on the bullet connector that sets separately for switchgear,
1.3 the transmission coupler of this main contact always is combined into a common interface also can be approaching from the drive unit front.
Spatially with respect to the direct coordination of its position of the switch indicating device, except improving operation comfort, avoided the danger of by means of operating parts master cock equipment the time, obscuring basically by operating parts.This is equally applicable to that the transmission coupler of main contact is rich in Promethean configuration, and is different with known switch equipment, and it is now no longer from drive unit cabinet back but directly just can be approaching from the drive unit front.By the signaling switch contact is concentrated on the bullet connector, can in this three-position type driving mechanism for switch, can connect a plurality of signaling switches contact simultaneously effectively by setting up socket connection.Therefore significantly reduced expenses, and correspondingly reduced survey fees usefulness owing to reduced error rate at the inner cabling of switchgear.
What a favourable design of the present invention had is characterized as
2.1 the transmission coupler of signaling switch contact and main contact is introduced on the multipolar system bullet connector.
By using the multipolar system bullet connector, can produce the core of a cable that (konfektionieren) switchgear is used basically by batch, and thereby help significantly to shorten installation time.
Description of drawings
Further specify the present invention by means of the embodiment that in two accompanying drawings, represents below, in the accompanying drawing:
Fig. 1 represents the driving front of three-position type driving mechanism for switch;
Fig. 2 is corresponding end view.
Embodiment
Fig. 1 represents the front surface A S of three-position type driving mechanism for switch.Operating parts shown in the figure is with respect to corresponding position of the switch indicating device particular arrangement spatially, for see clearer for the purpose of, only indicated an operating parts BE and position of the switch indicating device SE thereof among the figure.The operating parts that is used for circuit-opening contact and ground contact, but realize by the axle of corresponding manual control in the known manner, and associated position of the switch indicating device is made up of signal plate movably, it shows the on off state of current existence.
In addition, bullet connector AE also being shown among the figure equally can be approaching from three-position type driving mechanism for switch front AS.
Fig. 2 is the end view of three-position type driving mechanism for switch shown in Figure 1.Show equally most clearly that here operating parts BE, position of the switch indicating device SE and interface SK can be approaching from drive unit front surface A S by operating personnel.
By seeing among the figure, the position of bullet connector AE is in the middle part in addition, and this has just greatly simplified the electric installation of this switchgear.
Claims (2)
1. three-position type driving mechanism for switch that confession, distribution switchgear are used, the signaling switch contact that it has operating parts and switch indicator and is connected by cable connecting arrangement, and have and can it is characterized in that from the transmission coupler of the approaching main contact of three-position type driving mechanism for switch rear side:
1.1 this operating parts (BE) and position of the switch indicating device (SE) are arranged in the zone of drive unit front (AS) in such a way,, by configuration adjacent to each other spatially, reach console switch function inerrably that is,
1.2 this signaling switch contact is introduced on the bullet connector that sets separately for switchgear (AE),
