Abstract
The present invention relates to a kind of gas isolated medium voltage switchgear equipment, this switchgear has the three-positions disconnector device for being positioned at three electric phases on single shared rotatable drive shaft.In order to realize the structure shared, three-positions disconnector device for three-phase is disposed in single common functions unit, and this common functions unit has substrate and framework and the mode after a part for the hermetic enclosure of installation switchgear can be installed in the shell of switchgear with substrate and/or framework.
Description
Technical field
The present invention relates to a kind of gas isolated medium voltage switchgear equipment, this switchgear has the three-positions disconnector device for being positioned at three electric phases on single shared rotatable drive shaft.
Background technology
In known hermetic type medium voltage switchgear equipment, three-positions disconnector device (three-positiondisconnectordevices) is assembled in shell, and the different parts of described device are mechanically secured in the different piece of the shell of switchgear.
This draws following problem:
-assemble complicated and expend time in, because accessibility is limited by the available open in the shell of switchgear.
-in the end must carry out the adjustment of three-positions disconnector device in assembly line.
-in the end must carry out the functional test of three-positions disconnector device in assembly line.
-from retail trader there the outside isolation switch device having obtained assembling be impossible.
Summary of the invention
Therefore the object of the invention is to overcome all these defects with the compact structure of easily adjustment in a pre-installation.
According to an aspect of the present invention, provide a kind of gas isolated medium voltage switchgear equipment, it has the three-positions disconnector device for three electric phases, this isolation switch device is with rotatable driving shaft, wherein: the described three-positions disconnector device for three electric phases is disposed in single common functions unit, and this common functions unit has the substrate be arranged in switchgear shell; Wherein, a frame installation is on described substrate, and substrate and/or framework become a part for the hermetic enclosure of switchgear after mounting, and wherein said driving shaft is fixing on said frame.
Essential characteristic of the present invention is: the three-positions disconnector device for three-phase is disposed in single common functions unit, and this common functions unit has substrate and framework and the mode after a part for the hermetic enclosure of installation switchgear can be installed in the shell of switchgear with substrate and/or framework.
Because better accessibility, this reduces assembling or set-up time.In addition, pre-assembled unit more easily adjusted before it is installed in switchgear shell.
Embodiment favourable is further that the fixed contact of isolation switch device is installed on substrate by integral type sleeve pipe, and this sleeve pipe can be connected to the bus of the solid insulation of the housing exterior of switchgear in addition.
This outside framework is installed on substrate, and driving shaft is fixed on framework.
Alternatively, grounding contact (earthcontact) is fixed to framework.
In addition very favourable embodiment is that described common functions unit is at the shell installing rear enclosed switchgear in a gastight manner.
In order to this air-tightness realizing shell is closed, a possible solution is, realized by welding after being installed in shell at this functional unit, or tightened with spiral by the parameatal potted component being used in the shell wherein placing functional unit and realize.
Accompanying drawing explanation
Embodiments of the invention shown in the drawings.
Fig. 1 illustrates the perspective view of the three-phase isolation switch device in single sharing unit.
Fig. 2 illustrates the shell of medium voltage switchgear equipment.
Embodiment
Fig. 1 illustrates the perspective view of the three-phase isolation switch device in single sharing unit.Movable contact is arranged to be operated by rotating driving shaft.The both sides of driving shaft are located and are fixed in the frame, and this frame installation is on substrate.Be fixed with irremovable contact in a substrate, described irremovable contact is installed on the sleeve pipe of integral type.These sleeve pipes are connected to external bus.
Therefore this sharing unit can before it is installed in the shell of switchgear assembled and adjustment.
In addition utilize external bus can easily and effectively carry out circuit connection.
Fig. 2 illustrates the shell of medium voltage switchgear equipment.Substrate above-mentioned will be installed on the opening of cover top portion.This substrate is by make shell be fixed by the mode that substrate is closed airtightly.Therefore substrate and its external bus system can only be seen in fig. 2.Be similar to the inside that those remaining parts be installed on substrate shown in Fig. 1 extend to shell, and closed hermetically by substrate.
This airtight closing can realize by substrate is welded to the sealing in the opening of shell.
