Definitions
- the invention relates to a metal-enclosed switchgear a gas-filled container and with one in the container arranged three-position switch for the switch positions ON, OFF and EARTHED, as well as in the container arranged switching tubes of a vacuum switching device, wherein the container bushings for connecting the three-position switch and the vacuum interrupters with outside the container arranged components of the switchgear.
- a switchgear with these features is for example made known by DE-A-42 11 155.
- the drive movement for the vacuum interrupters is carried out by means of a gas-tight plunger bushing the container wall to the vacuum interrupters.
- Switchgear with circuit breakers are not suitable for the operation of industrial plants with motors because these are switched on and off relatively frequently.
- the drive devices In contrast, circuit breakers are for one relatively low switching frequency. It has therefore proven to be useful, for operational switching on and off motor drives with operating voltages in the lower medium voltage range, e.g. B. 6 or 10 kV, vacuum switching devices to use in the form of contactors and this together with other required components on one Insert or carriage of an air-insulated, metal-enclosed To accommodate switchgear.
- An example of this shows EP-B-0 263 396.
- a switchgear includes both general energy supply an industrial plant in the field of medium voltage as well as larger motor drives that come from the medium voltage network different types of Control panels for use, namely partially gas-insulated Control panels with vacuum circuit breakers and air-insulated Control panels with vacuum contactors.
- the invention has for its object the structure of To simplify switchgear of the type mentioned.
- an electromagnetic belonging to the vacuum switching device Drive device also in the switchgear container is arranged and that the vacuum switching device the design of protection.
- commercially available vacuum contactors can be used.
- the electromagnetic drive device such Contactors are dimensioned for operation in atmospheric air and therefore by a pressure deviating from the atmospheric pressure the function of the insulating gas in the switchgear container of the vacuum contactor can be changed.
- the im In connection with the invention considered area of Operating voltages in the lower medium-voltage range however, not significantly above atmospheric pressure Pressure of the sulfur hexafluoride gas usually used as the insulating gas needed.
- Atmospheric pressure selected that is suitable the diffusion of moisture or other foreign gases to prevent in the container. It can therefore be sufficient to choose a vacuum contactor in a standard version and adjust its drive device like this for example for places with increased air pressure, e.g. B. in Mining underground, is provided. Vacuum contactors with one such setting device are already known (DE-C-33 23 861).
- the design of a multi-panel switchgear has been proven a narrow design of the individual fields is advantageous. According to an embodiment of the invention, this can be done achieved that the three-position switch in the upper Area of the container and the vacuum switchgear below the Three-position switch arranged in the lower part of the container is and that at least for each pole of the vacuum switching device two outgoing feedthroughs on the front and / or are provided on the underside of the container.
- a surge suppressor connect outside the gas-filled container. This facilitates the assembly, testing and monitoring of the surge suppressor.
- motor drives form operating voltages an important one in the lower mean voltage range Application of the invention. Doing the job occur, a motor drive with changing direction of rotation, d. H. in turning operation. For this it is known to use two vacuum contactors, one of which is the motor switches with reversed phases. After an arrangement of the invention, the two are for an engine turning control required vacuum switchgear housed in separate containers, whereby additional to produce a phase crossing Bushings are provided on both containers.
- the circuit diagram according to FIG. 1 shows schematically one Switchgear 1 with an overhead busbar 2, the runs outside a container 3 filled with insulating gas.
- a Three position switch 4 the positions ON, OFF and EARTHED.
- a connection is established in the ON position the busbar 2 to a likewise outside the container 3, expediently arranged in its immediate vicinity HV fuse 5 manufactured.
- a vacuum contactor 6 one on the outlet side front bushing for one cable connection and two Bushings are arranged in a lower container wall. While one of the lower implementation is an additional one Outgoing connection represents, is to the other implementation Surge limiter 7 connected.
- One to the vacuum contactor 6 belonging electromagnetic drive device 8 is also in container 3.
- FIGS. 2 and 3 are the outlines of the metal encapsulated Switchgear 1 with the circuit according to Figure 1 closer evident.
- the container 3 is substantially flat Wall parts on, but with a suitable stiffening can be provided to one above atmospheric pressure to withstand internal gas pressure without significant deformation.
- the switchgear is essentially cuboid Provide container 3 with recesses locally.
- the container 3 has a recess on its front side above as a support for a low voltage box 10, in which controls and controls as well as measuring instruments are located.
- a further recess is provided at the end of the container 3, which corresponds approximately to the depth of cable angle plugs.
- a such angled connector 11 is in connection with FIG an implementation 12 shown.
- FIG can be seen that the container 3 in the upper left area has further indentation, the depth of insulating housings 13 for HV fuses (position 5 in Figure 1). Of the Three-position switch 4 is arranged so that its Axis of rotation runs horizontally and on the front 14 of the Container 3 is accessible. There is also one Drive device 15.
- the vacuum contactor 6 is located below the three-position switch 4 in the lower area of the container 3 and is the outlets 12 adjacent.
- the one of the lower bushings 16 is used to connect the surge suppressor 7 ( Figure 1) while the remaining implementation 17 is provided in the event that the shown Control panel in connection with an identical or similar one Control panel to be used for a turn control.
- busbar 2 indicated in Figure 1 is in the Figures 2 and 3 not shown. However, are implementations 20 shown to connect the three-position switch 4 serve with the busbar 2.
- the vacuum contactor 6 accordingly has three Vacuum interrupters 21 on. To illustrate that the same design of the vacuum contactor 6 provided for different Operating voltages are suitable are vacuum interrupters 21 different sizes shown.
