Abstract
Products applied to a 12KV, 50Hz power system, relate to a switching device as distribution of electric power and control, specifically to an SF6 complete insulating and panseal rig net switch cabinet. The rig net switch cabinet comprises a cabinet body, an operating mechanism and an air box, wherein the air box and the operating mechanism are arranged in the cabinet body; upper and lower bus bars electrically connected and at least a triple-pole switch are arranged in the air box; a coil in bushing is electrically connected with a lower bus bar; at least a coil out bushing is electrically connected with an upper bus bar, wherein the coil out bushing is electrically connected with the triple-pole switch, and is arranged at a grounding end of the triple-pole switch. When the rig net switch cabinet is used as the coil in cabinet, the outgoing line is provided with grounding functions, and expansion is agile. The invention is an SF6 complete insulating and panseal rig net switch cabinet with convenient connection.
Description
Technical Field
The product is applied to a 12kV and 50Hz power system, relates to a switch device for electric energy distribution and control, and particularly relates to SF6Totally enclosed looped netowrk cubical switchboard of all insulation.
Background
Currently SF6A series of medium-high voltage products are available for a gas full-insulation and full-sealing ring network switch cabinet, and in the products, all high-voltage primary parts are sealed and filled with SF6The air box is not influenced by the change of the external environment, is more suitable for being used in areas with severe environment than the common air insulation switch cabinet, has wider application range and higher safety, but the common switch cabinet does not have the outlet wire grounding function when being used as the inlet wire function, thereby bringing the hidden trouble of power utilization of users,there is a problem in terms of safety of electricity usage.
Disclosure of Invention
The invention aims to provide a ring network switch cabinet with electric safety.
In order to achieve the purpose, the invention provides the following technical scheme:
the ring network switch cabinet comprises
The gas tank and the operating mechanism are both positioned in the cabinet body;
an upper bus bar, a lower bus bar and at least one three-pole switch which are electrically connected are arranged in the air box;
the wire inlet sleeve is electrically connected with the lower bus bar;
at least one outlet bushing is electrically connected with the upper busbar;
wherein,
the outgoing line sleeve is electrically connected with the upper bus bar through the three-pole switch and is arranged at the grounding position end of the three-pole switch.
When the ring network switch cabinet is used as an incoming cabinet, the outgoing line has a grounding function, is flexible to expand and is convenient to connect6Totally enclosed looped netowrk cubical switchboard of all insulation.
Drawings
Fig. 1 is a cross-sectional view of the ring network switch cabinet of the present invention in one direction;
fig. 2 is a cross-sectional view of the ring network switch cabinet of the present invention in another direction.
The present invention will be further explained with reference to the drawings and examples.
Detailed Description
The utility model discloses when the looped netowrk cubical switchboard was used as the inlet wire cabinet function, it had the function of connecting to be qualified for the next round of competitions, and the extension is nimble moreover, connects convenient SF6 totally enclosed looped netowrk cubical switchboard.
SF (sulfur hexafluoride)6The totally-insulated and totally-enclosed looped network switch cabinet comprises SF6The air box comprises an air box 1, an operating mechanism 7 and a cabinet body 6, wherein the air box 1 and the operating mechanism 7 are both positioned in the cabinet body 6. There is electrical connection's last generating line row 4 in the gas tank 1, generating line row 2 down, the tripolar switch 3 of the three stations of multiunit, inlet wire sleeve 8 and outlet sleeve 5 etc., inlet wire sleeve 8 is located gas tank 1 under, inlet wire sleeve 8 and 2 electrical connection of lower generating line row, two sides of the top are equipped with behind tripolar switch 3 with last generating line row 4 electrical connection's outlet sleeve 5 about the cabinet body 6, outlet sleeve 5 is at tripolar switch's earthing position end, also can realize taking earthing function at the outlet end, better guarantee user's power consumption safety. The three states corresponding to the three-position three-pole switch 3 are respectively: first, disconnection, namely, the upper bus bar 4 is disconnected from the lower bus bar 2; secondly, switching on, namely, the upper bus bar 4 is connected with the lower bus bar 2; thirdly, the outgoing line sleeve is grounded, namely the outgoing line sleeve 5 is grounded, so that the outgoing line grounding function is realized.
According to the structure, the incoming line sleeve 8 of the ring network switch is positioned below, and the outgoing line sleeve 5 is positioned on two sides above the cabinet body, namely, outgoing lines are arranged on the upper incoming line of the lower part.
Of course, the ring network switch cabinet of the utility model can also be deformed by other components. In conclusion, obvious variations from the above description of embodiments, as well as other modifications, which do not depart from the essence of the invention, are intended to be included within the scope of the appended claims.
