Abstract
The present invention relates to a gas-insulated medium-voltage switchgear comprising a three-position disconnector for three electric phases on one common rotatable drive shaft. In order to implement a common configuration, one common functional unit, which is provided with a base plate and a frame and which can be mounted in the switchgear housing in such a way that the base plate and / or the frame become part of the airtight housing of the switchgear after mounting, The three-position disconnecting device for three phases is disposed.
Description
The present invention relates to a gas-insulated medium-voltage switchgear comprising a three position disconnector device for three electric phases on one common rotatable drive shaft.
In a well-known airtight medium voltage switchgear, the three-position disconnector device is assembled to the housing in such a way that the different components of the device are mechanically fixed to different parts of the housing of the switchgear.
This leads to the following problems.
- Accessibility is limited by the available openings in the housing of the switchgear, which complicates assembly and is time consuming.
- The adjustment of the 3-position disconnecting device shall be made in the final assembly line.
- The functional test of the 3-position disconnector device shall be made on the final assembly line.
- External sourcing (outsourcing) of a fully assembled disconnector device from a subcontractor is not possible.
It is therefore an object of the present invention to overcome all of these drawbacks with a compact construction that is easy to adjust prior to mounting.
A basic feature of the invention is that it comprises a base plate and a frame, said base plate and / or frame being mounted on a common functional unit (1), which can be mounted on the switchgear housing in such a way that it becomes part of the airtight housing of the switchgear functional three-position disconnector device is disposed in the functional unit.
Another advantageous embodiment is that the stationary contact of the disconnector device is mounted to the base plate by means of an integral bushing and the integral bushing can also be connected to a solid insulated busbar at the outer part of the housing of the switchgear.
In addition, the frame is mounted on the base plate, and the frame is provided with a fixture for the drive shaft.
Optionally, the ground contact is fixed to the frame.
Another advantageous embodiment is that the housing of the switchgear is closed after the common functional unit is mounted in an airtight manner.
To achieve this gastight closing of the housing, one possible solution is to either mount it in the housing followed by welding, or screw it with a sealing element around the opening of the housing in which the functional unit is located .
One embodiment of the invention is shown in the figures.
This saves assembly or mounting time due to better accessibility. In addition, the preassembled unit is easier to adjust before being mounted to the switchgear housing.
1 is a perspective view of a three-phase disconnector device in one common unit;
2 is a view showing a housing of a medium voltage switchgear.
Figure 1 shows a perspective view of a three-phase disconnector device in one common unit. And the movable contact is arranged to be operable by the rotatable drive shaft. The drive shaft is disposed and fixed on both sides of the frame mounted on the base plate. The base plate is secured with a non-movable contact mounted on the integral bushing. These bushings are connected to an external bus bar.
Thus, the common unit can be assembled and adjusted before being mounted in the housing of the switchgear.
Also, power supply by the external bus bar is easy and effective.
Fig. 2 shows the housing of the medium voltage switchgear. The aforementioned base plate is mounted to the opening of the upper end of the housing. The base plate is fixed so that the housing is hermetically closed by the base plate. So only the base plate with its external busbar system is visible in Fig. The remaining components mounted on the base plate, as shown in Figure 1, extend inwardly of the housing and are hermetically closed by the base plate.
This hermetic closure can be realized by welding the base plate to the opening of the housing or by sealing.
