Abstract
The utility model provides a kind of mounting structure of metal-clad moveable high-voltage switchgear current transformer, including the bus-bar room and current transformer being located in switchgear, the current transformer is lifted on the bottom of the bus-bar room, one terminals of the current transformer are connected to mouth under the breaker in the switchgear by busbar, and another terminals are connected with the busbar extended to outside the switchgear cabinet top.Busbar length needed for the utility model connection current transformer integrally shortens, and reduces cost, and do not interfere with performance and the safety of switchgear.
Description
Technical field
The utility model is related to a kind of high-tension switch cabinet, especially a kind of metal-clad moveable high-voltage switchgear electric current is mutual
The mounting structure of sensor.
Background technology
At present in electric system, high-tension switch gear is mostly using the metal armored movable high pressure with vacuum circuit breaker
Switchgear.Include bus-bar room and the breaker chamber for being equipped with vacuum circuit breaker in metal-clad moveable high-voltage switchgear.Vacuum
Mouth laterally penetrates partition board and stretches into the cable vault below bus-bar room under the breaker of breaker.
Busbar can be extended in a power distribution system from cable vault outside switchgear cabinet top by aerial inlet wire.Current transformer
(CT) it is mounted on cabinet rear column now, a terminals of current transformer are connected to mouth under breaker by busbar, another
Terminals are connected to the busbar extended on the outside of cabinet top.But this mounting means can use more busbar, production cost higher.
Utility model content
The utility model offer is a kind of to save busbar, reduce cost and can guarantee that switchgear performance and safety do not change
Metal-clad moveable high-voltage switchgear current transformer mounting structure.
To achieve the goals above, the technical solution that the utility model is taken is：
The mounting structure of the metal-clad moveable high-voltage switchgear current transformer, including be located in switchgear
Bus-bar room and current transformer, the current transformer are lifted on the bottom of the bus-bar room, one wiring of the current transformer
End is connected to mouth under the breaker in the switchgear by busbar, and another terminals, which are connected with, extends to the switchgear cabinet top
Outer busbar.
The busbar extended to outside the switchgear cabinet top includes the vertical section for being parallel to the busbar outdoor unit side, is parallel to
The horizontal segment and bending part connecting the two of the bus-bar room bottom surface.
Further include the insulator for being vertically mounted on the busbar outdoor unit side, vertical section phase vertical with the insulator
Even.
The terminals of the current transformer under the breaker mouth it is highly consistent.
Using above-mentioned technical proposal, after improvement under the terminals to breaker of current transformer mouth Distance Shortened, and count
Enter the busbar length extended to outside the switchgear cabinet top, the busbar length needed for structure connection current transformer integrally shortens
, cost is reduced, and do not interfere with performance and the safety of switchgear.
The busbar for extending to switchgear top outer includes part parallel with bus-bar room side and bottom surface respectively.So
Busbar length can be enabled most short under the premise of keeping spacing between busbar and bus-bar room, and the terminals of current transformer with it is described
Mouth is highly consistent under breaker, can also allow busbar length connecting the two most short.The busbar extended to outside switchgear cabinet top is long
Degree is longer and needs to be bent, therefore supports and position by the insulator on the outside of bus-bar room, improves aerial
The stability of the busbar of inlet wire.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Label in figure be：
1. mouth, 4. current transformers, the big bent plate of 5. bus-bar rooms, 6. insulation under bus-bar room, 2. breaker chambers, 3. breakers
Son, 7. busbars.
Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present invention further detailed
Explanation, with help those skilled in the art to the present utility model design, technical solution have it is more complete, accurate and deeply
Understanding.
There is bus-bar room 1, breaker chamber 2 and cable vault in high-tension switch cabinet.Bus-bar room 1 be by the big bent plate 5 of bus-bar room, every
The space that plate and cabinet top plate are separated out together.Bus-bar room 1 is the cable vault of inlet wire outside, in the prior art current transformer 4
On cabinet rear column, also in cable vault.
As shown in Figure 1, the utility model provides a kind of peace of metal-clad moveable high-voltage switchgear current transformer
Assembling structure, including the bus-bar room 1 and current transformer 4 that are located in switchgear.Current transformer 4 is lifted on the big bent plate of bus-bar room 5
Bottom, the terminals of current transformer 4 are downward.4 one terminals of current transformer are connected to the open circuit in switchgear by busbar 7
Mouth 3 under device, another terminals are connected with the busbar 7 extended to outside switchgear cabinet top.
The busbar 7 extended to outside switchgear cabinet top includes the vertical section for being parallel to 1 lateral surface of bus-bar room, is parallel to bus-bar room
The horizontal segment and bending part of 1 bottom surface, bending part connect horizontal segment and bending part.Big 5 lateral surface of bent plate of bus-bar room also right angle setting
There is insulator 6.Insulator 6 at least there are two.The equal length of all insulators 6, and with the vertical section vertical connection.So
Order 7 length of busbar outside switchgear cabinet top can be extended under the premise of keeping spacing between busbar 7 and the big bent plate 5 of bus-bar room most
It is short.
After improvement under the terminals to breaker of current transformer 4 mouth 3 Distance Shortened.Because of current transformer 4
Under the busbar 7 entered from switch cabinet jacking and breaker between mouth 3, therefore it is included in the busbar 7 extended to outside switchgear cabinet top
Afterwards, 7 total length of busbar being connected with current transformer 4 also shortens.This configuration reduces the costs of required busbar 7, and not
It can influence performance and the safety of switchgear.
As a further improvement, can allow current transformer 4 terminals under the breaker mouth 3 it is highly consistent.
The distance of mouth 3 is most short under terminals to breaker in this way, can further decrease the length of busbar 7 connecting the two.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as using changing for the various unsubstantialities that the utility model methodology and technical solution carry out
Into, or it is not improved by the utility model design and technical solution directly apply to other occasions, the utility model protect
Within the scope of shield.
