Definitions
- the invention relates to an insulating body for a medium-voltage switchgear with a busbar side terminal and a cable outlet, in which an insulating body is embedded a circuit breaker and the first connected to the circuit breaker contact point as a bearing for a movable switching contact of a circuit breaker and another contact point for the movable switching contact wearing .
- Such an insulating body is known from international patent application WO 2004/040728.
- a circuit breaker is embedded together with Betschistsme ⁇ mechanism.
- a movable switching contact of a circuit breaker is mounted on a first contact point of the insulating body.
- the insulating body has a further Kon ⁇ in timing location with the movable switching contact of the switch disconnector according to the first point of contact between the other contact point and a grounding contact of the gas-insulated With ⁇ telnapssschaltstrom is pivotable.
- a grounding derar- term operation is performed by the movable switching contact is brought connection with the grounding contact in United ⁇ and switching contacts of the scarf ⁇ ters are closed.
- Such a grounding process is common in gas-insulated medium-voltage switchgear in primary energy distribution networks.
- Object of the present invention is to provide an insulating body of the type mentioned, which allows a manufacturing technology favorable construction of medium voltage switchgear generally for primary and Sekundärenergieverteilungs- networks with a simultaneous reduction of costs.
- this object is achieved in an insulating body of the type specified in that the further contact point is also designed as a bearing for the movable switching contact, the movable switching contact is optionally mounted instead of the first at the other contact point and the other contact alternatively connected to the busbar side terminal to the cable outlet.
- Such an inventive insulating body can be used advantageously both in a gas-insulated or in an air-insulated medium voltage switchgear.
- a simplified production of medium-voltage switchgear is Lich both for primary and for secondary energy distribution networks mög ⁇ as an insulating one and the same embodiment for medium-voltage switchgear of the two power distribution networks can be used. This reduces production costs by reducing the number of different parts.
- the movable portion in a preferred embodiment, the movable
- Switching contact by means of an actuating mechanism connectable to a ground contact, which is optionally arranged opposite instead of the wei ⁇ direct contact point of the first contact point.
- a ground contact which is optionally arranged opposite instead of the wei ⁇ direct contact point of the first contact point.
- Figure 1 is a schematic representation of a gas-insulated
- Figure 2 is a schematic representation of a gas-insulated medium voltage switchgear in a second embodiment .
- FIG. 1 Shown in Figure 1 is a gas-insulated medium-voltage switchgear ⁇ 1, wherein the busbars 2, 3, 4 via a busbar side connector 5 are connected to an insulating body 6 of the medium-voltage switchgear.
- a disconnect switch 7 comprises a movable switching contact 8, which is pivotably mounted on a first contact point 9, and whose free end is between a further contact point 10 and one on the housing of the medium-voltage switchgear 1 ⁇ arranged grounding contact 11 is pivotable;
- the further contact point 10, which is conductively connected to the busbar side terminal 5, is also formed as a bearing point and thus prepared for a bearing of the movable switching ⁇ contact 8 of the circuit breaker 7.
- the contact ⁇ places 9 and 10 are integrally formed and partially embedded in the insulating body. But it is also possible and may be advantageous to carry out the two contact points in each case in several parts, each by a contact carrier is embedded in the insulating body that a comparatively short end protrudes and a contact ⁇ or bearing element is attached to this short end.
- the circuit breaker 7 is mechanically coupled to an externally activatable actuating mechanism 12.
- a circuit breaker 13 with terminals 14, 15 embedded for a movable contact, not shown, and also not illustrated ⁇ fixed contact.
- the movable contact of the circuit breaker 13 is actuated via an externally activatable actuation device 16 for closing and opening the circuit breaker 13.
- the terminal 14 is conductively connected to the first contact point 9 of the circuit breaker 7 and the terminal 15 with a cable outlet 17.
- the medium-voltage switchgear according to Fig. 1 is a conventional ⁇ employed in the primary power distribution networks, but can also be used readily in the secondary distribution networks.
- the movable switching contact 8 is pivotable between three possible positions. In a first position shown in dashed lines, the free end of the movable switching contact is connected to the further contact point 10. In this position, via a triggering of the actuator 16 and a closing or opening of the contacts of the Circuit breaker 13, a connection between the busbar ⁇ rails 2, 3, 4 and the cable outlet 17 are formed so that the power switch 13 is used for switching or interrupting the energy provided to the busbars to the cable outlet 17. In a second position, also shown by dashed lines, the free end of the movable switching contact 8 is in contact with the grounding contact 11 of the medium-voltage switchgear 1. In this position of the disconnector 7, a grounding operation of the medium-voltage switchgear 1 is prepared.
- the circuit breaker 13 is used for grounding by closing the contacts of the circuit breaker 13 via the actuator 16. If the contacts of the vacuum switch 13 are closed and the disconnecting switch 7 is in its second position, then the gas-insulated medium-voltage switchgear 1 is earthed. In a third position shown by a solid line is the free end of the movable switching contact 8 with none of the contact points 9,10 in connection, this position corresponds to an off position of the gas-insulated medium voltage switchgear 1. The pivoting of the movable switching contact 8 between the different positions is doing performed over the externally accessible actuating mechanism 12.
- FIG. 2 shows a gas-insulated medium-voltage switchgear
- the power switch 13 serves to transmit the available to the bus bars 2, 3, 4 Energy to the cable outlet 17.
- the movable switching contact 8 can be pivoted about the further contact point 10 in a flat ⁇ if shown by dashed second position in which the free end of the movable switching contact. 8 is in communication with the ground contact 11 '. In this second position, the cable outlet 17 of the gas-insulated
