Abstract
The invention relates to a gas insulated medium voltage switchgear with a 3 position disconnector device for 3 electric phases on one common rotatable driveshaft. In order to realize a common construction, the three position disconnector device for three phases is arranged in one common functional unit, which has a base plate and a frame, and which can be mounted in a switchgear housing, in that way, that the baseplate and/or the frame is after the mounting a part of a gastight housing of the switchgear.
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 that is used to be positioned at three electric phases on the single shared rotatable drive shaft.
Background technology
In known hermetic type medium voltage switchgear equipment; Three-positions disconnector device (three-position disconnector devices) is assembled in the shell, makes the different parts of said device be mechanically secured on the different piece of shell of switchgear.
This draws following problem:
-assembling is complicated and expend time in, because accessibility is by the available opening restriction in the shell of switchgear.
-in the end carry out the adjustment of three-positions disconnector device in the assembly line.
-in the end carry out the functional test of three-positions disconnector device in the assembly line.
-outside to obtain the isolation switch device of accomplishing assembling be impossible from retail trader there.
Summary of the invention
Therefore the objective of the invention is to overcome all these defectives with the structure of the compactness of easy adjustment before installation.
Essential characteristic of the present invention is: the three-positions disconnector device that is used for three-phase is disposed in single common functions unit, and this common functions unit has substrate and framework and can be installed in the shell of switchgear with substrate and/or the mode of framework after the part of the hermetic enclosure of installation switchgear.
Because better accessibility, this reduces assembling or set-up time.In addition, pre-assembled unit adjustment more easily before it is installed in the switchgear shell.
Further advantageous embodiments is that the fixed contact of isolation switch device is installed on the substrate through the integral type sleeve pipe, and this sleeve pipe can be connected to the bus of solid insulation of the housing exterior of switchgear in addition.
This outside framework is installed on the substrate, and driving shaft is fixed on the framework.
Alternatively, grounding contact (earth contact) is fixed to framework.
Very advantageous embodiments is that said common functions unit is at the shell that the rear enclosed switchgear is installed with air tight manner in addition.
In order to realize this air-tightness sealing of shell; A possible solution is; Through realizing through welding after being installed at this functional unit in the shell, or tighten with spiral through the parameatal potted component that uses the shell of placing functional unit therein and to realize.
Description of drawings
Embodiments of the invention shown in the drawings.
Embodiment
Fig. 1 is illustrated in the perspective view of the three-phase isolation switch device in the single sharing unit.Removable contact is arranged to through rotating driving shaft operation.The both sides of driving shaft are located and are fixed in the framework, and this framework is installed on the substrate.In substrate, being fixed with can not mobile contact, said can not being installed on the sleeve pipe of integral type by mobile contact.These sleeve pipes are connected to outside bus.
Therefore this sharing unit can assembled and adjustment before it is installed in the shell of switchgear.
Utilize the outside bus can be easily and carry out circuit effectively and connect in addition.
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 incited somebody to action so that shell is fixed by the mode that substrate seals airtightly.Therefore in Fig. 2, can only see substrate bus-bar system outside with it.Be similar to shown in Fig. 1 those and be installed in the inside that remaining part on the substrate extends to shell, and sealed hermetically by substrate.
This airtight sealing can realize through the sealing in the opening that substrate is welded to shell.
