Abstract
To decrease the number of components by providing an enclosure for housing in interrupter unit with a plurality of connection ports thereby eliminating the need of a dedicated connection port. An enclosure 1 for housing an interrupter unit of a composite gas insulated switchgear having single bus structure is connected, at a connection port 2 thereof, with the interrupter of main bus through a main bus disconnector 4. Furthermore, a moving cable 6 is connected through a cable adaptor 5 with a connection port 3 disposed below the connection port 2. The connection port 2 is connected, on the front thereof, with a cable head 19 provided on a frame 20 incorporating a CT for passing thecable. This structure decreases the number of components and reduces the manufacturing cost. The main bus interrupter serves as a protector against the faults occurring frequently on the side closer to the main bus than the disconnector 4 and the moving cable is used continuously for receiving and transmitting power.
Description
The present invention relates to a kind of complex type gas insulated switchgear system, it has a cable adaptor, and moving cable is linked on the bus, and this bus is arranged in a container, and one of this container dressing comprises the switch element of a gas-insulated switch (following with GIS for it).
A kind of common example is shown among Fig. 1 and 2, and its circuit diagram is shown in Fig. 3.In Fig. 1,2, a moving cable 6 is used to test the GIS unit; Cable adaptor 5,5a or a 5b by a connector 7 or 8, link main bus bar 9 with moving cable 6.
In Fig. 1 and 2, numeral 1 expression one switch element; 2, connector of 3 expressions; 4,4a, 4b represent a bus isolating switch; Main parent of 9 expressions; 10 expression GIS; The control cabinet of 11 expression isolating switches; A container of 12 expression main bus bars and its isolating switch; An insulation of 13 expressions supporter (partition spare); 14,14a or 14b represent a branch bar; Unit controls case of 15 expressions; The controlling organization of 16 and 17 expression GIS.
In the common moving cable connected system, use a special-purpose connector 7,8 that cable adaptor is linked bus, as mentioned above, and, select a suitable installation site for use according to special-purpose.
Thereby the increase of system element quantity is a problem.And when main bus bar side 9 places of isolating switch 4,4a, 4b produced line to ground fault, GIS can not be as a protector, and this is because the link position of moving cable is limited in sidepiece to send feed element (or bank unit).
Japanese Laid-Open Patent Application No.60-183911 (1985) discloses a kind of example of such gas-insulated switch.
The purpose of this invention is to provide a kind of gas insulated switchgear system, it has a cable adaptor, and moving cable is electrically connected to a link position between isolating switch and the gas-insulated switch through other a plurality of connectors.
In order to achieve the above object, characteristics of the present invention are, several connectors are contained in the container, and this container accommodates switch element, so that GIS is as a protector.
The switch element of GIS of the present invention always comprises a plurality of connectors.They are provided as a standardized part, and corresponding to list/pair two kinds of bus structures.
In the single busbar connection structure situation and since connector 2 or 3 all need not, one object of the present invention is used connector by cable adaptor, connects the motion cable and reaches.
Fig. 1 illustrates a conventional embodiment, and one of them motion cable adaptor is linked a bus end.
Fig. 2 illustrates a conventional embodiment, and the special-purpose connector to the feed element cable adaptor wherein is housed.
Fig. 3 is the circuit diagram of Fig. 2 example.
Fig. 4 is the schematic diagram of one embodiment of the invention, and wherein the motion cable is linked switch element.
Fig. 5 is a circuit diagram embodiment illustrated in fig. 4.
Embodiments of the invention are described as follows shown in the Figure 4 and 5.
As one embodiment of the present of invention, Fig. 4 illustrates the method for attachment of a moving cable 6,6a, 6b, with check gas-insulated switch unit 1; Cable is linked connector 3,3a or the 3b that is contained in the container, and this container is accommodating the switch element 1 that comprises GIS.
Under the single busbar connection structure situation, it is unnecessary that connector 3,3a or a 3b of switch element 1 becomes, and cable adaptor 5,5a or a 5b who links movable cable 6,6b links a link position between isolating switch 4,4a or 4b and switch 10,10a or the 10b by a connector 3,3a or 3b.
Among Fig. 4, an isolating switch 4 is linked bus at connector 2; Movable adapter 5,5a or 5b link bus at connector 3; But this position is closed and is tied up under the reverse situation and can also use by the same manner.
Numeral 18 is represented a cable end container; 19 represent a cable end; 20 represent a flat board; 21 represent a through-type current transformer.
Among this embodiment of the present invention, be connected in cable adaptor 5,5a, 5b on movable experiment cable 6,6a, the 6b and link the connector of the container of a dressing ordinary tap unit, described ordinary tap unit installs under stube cable fortune orchestration 5, the special-purpose connector of 5a, 5b to (chewing) 7,8 situations not having.
Therefore, if break down in main bus bar side 9 places of an isolating switch 4, then can when electric power sends or receive, movable test cable 6 be linked main bus bar.
According to the present invention, owing to use the connector (switch element) that has installed, it is unnecessary that the special-purpose connector of cable adaptor becomes, and then number of elements, cost cost are reduced, and construction GIS becomes simple.
Simultaneously; when main bus bar side 9 places of isolating switch 4 occur that for example line is to earth fault; because moving cable is linked a link position between GIS and the isolating switch, then may by be protector with GIS electric power transmit receive in special movable experiment cable 6 link main bus bar.
