Abstract

The utility model provides a double-bus-chamber conjoined gas insulation switch equipment bus room. In the bus room, the two same and independent bus rooms of original adjacent cabinet bodies are designed into one body and an independent operation function of three station mechanisms respectively is maintained. The novel bus room is simple in structure. Material cost of the bus room and material cost needed during cabinet consolidation are greatly saved. On-site cabinet consolidation efficiency is increased. And a gas leakage risk and an insulation risk which are probably caused because cabinet consolidation quality is poor are reduced.

Description

The gas-insulated switchgear bus-bar room that double-bus chamber is conjuncted

Technical field

The utility model belongs to power product technical field, relates to gas-insulated switchgear field, is specifically related to a kind of bus-bar room of gas-insulated switchgear.

Background technology

Generally, SF6 gas insulation switch cabinet, when application, during two adjacent cabinet splicings, need be spliced into one by its bus-bar room by related accessories.

Fig. 1 is the bus-bar room of an existing cabinet.During work, housing 11 connects with next door cabinet housing, and electric current is through bus socket 12, then to contacts 17 in the middle of bus bar copper row 13, branch row 14, fixed contact 15, three station moving contacts 16, three stations, finally to wall bushing 18, receives breaker chamber again; When three station moving contacts 16 are transferred to ground connection position, be connected with grounding contact 19, wall bushing is to the line-to-ground of breaker chamber side.

Shown in Fig. 2 and Fig. 3, be respectively two bus-bar room schematic diagrames after two bus-bar rooms splicing schematic diagrames of the adjacent cabinet of existing gas insulation switch cabinet and adjacent cabinet have spliced.During work, the electric current of two adjacent cabinets 21 is through bus bar copper row 13, the bus socket 12 of a cabinet body, by splicing annex used: connecting copper pipe 23, then to bus socket 12, the bus bar copper row 13 of an other cabinet body, form with the operating characteristic described in Fig. 1.Wherein insulating sleeves 22 plays the insulation protection effect of stitching portion.

In prior art, two adjacent cabinets, when splicing, pay particular attention to owing to spelling the cabinet Leakage Gas risk causing of poor quality and insulation risk.Therefore the splicing of the bus-bar room between cabinet has taken a large amount of time, cost.The utility model proposes a kind of brand-new bus-bar room, by two of original adjacent cabinet independently identical bus-bar room be designed to one, but still keep original three position mechanism function of independent operation separately; It is simple in structure, greatly saved the Material Cost of bus-bar room and when splicing between adjacent cabinet required Material Cost, improved the efficiency of on-the-spot spelling cabinet, reduced the above-mentioned possible risk of mentioning.

Utility model content

It is simple in structure that the purpose of this utility model is to provide, the gas-insulated switchgear bus-bar room that cost-saving double-bus chamber is conjuncted, it comprises housing, bus socket, bus bar copper row, two branch rows, also comprises two three-stations, and described each several part is linked in sequence.

According to most preferred embodiment of the present utility model, each of two three-stations described in the conjuncted gas-insulated switchgear bus-bar room in double-bus chamber includes contact and grounding contacts in the middle of fixed contact, three station moving contacts, three stations.The operating function of two three-stations is separate.

According to most preferred embodiment of the present utility model, in the middle of bus socket, bus bar copper row, the first branch row, the first fixed contact, the one or three station moving contact, the one or three station, contact and the first wall bushing form loop.In the middle of bus socket, bus bar copper row, the second branch row, the second fixed contact, the two or three station moving contact, the two or three station, contact and the second wall bushing form loop.

According to most preferred embodiment of the present utility model, bus bar copper row is directly connected with bus socket in the mode of single long copper bar.Housing outward appearance total length is 800-1600 millimeter.

This novel bus cell structure is simple, greatly saved the Material Cost of bus-bar room and when spelling cabinet required Material Cost, improved the efficiency of on-the-spot spelling cabinet, reduced because spelling the cabinet Leakage Gas risk that may cause of poor quality and insulation risk.

Accompanying drawing explanation

Figure 1 shows that the bus-bar room of existing gas insulation switch cabinet;

Figure 2 shows that two bus-bar room spliced maps of the adjacent cabinet of existing gas insulation switch cabinet;

Figure 3 shows that two bus-bar rooms after the adjacent cabinet of existing gas insulation switch cabinet has spliced;

Figure 4 shows that the gas-insulated switchgear bus-bar room structural representation that double-bus of the present utility model chamber is conjuncted.

Embodiment

Below with reference to accompanying drawing, the specific descriptions of optional execution mode of the present utility model have been provided.

Figure 4 shows that the gas-insulated switchgear bus-bar room structural representation that double-bus chamber is conjuncted, figure comprises housing 41, bus socket 42, bus bar copper row 43, two branch rows 44,54, also comprises two three-stations, and described each several part is linked in sequence.It by two of original adjacent cabinet independently identical bus-bar room be designed to one, but still keep original three position mechanism function of independent operation separately.

Wherein first three-station comprises first fixed contact 45, first three stations moving contact 46, the middle contact 47 of first three station and first grounding contact 49.Second three-station comprises contact 57 and second grounding contact 59 in the middle of first fixed contact 55, second three station moving contacts 56, second three station.

During work, housing 41 (the housing integrators of original two bus-bar rooms) still splices with next door cabinet, electric current is through bus socket 42, arrive again bus bar copper row 43, first branch row 44, first fixed contact 45, first three stations moving contact 46, the middle contact 47 of first three station, finally to wall bushing 48, receive again breaker chamber; When first three stations moving contact 46 is transferred to ground connection position, be connected with first grounding contact 49, wall bushing is to the line-to-ground of breaker chamber side.Wherein, bus bar copper row 43 is that mode with single long copper bar is directly connected with bus socket 42.

Same electric current is through bus socket 42, then to contacts 57 in the middle of bus bar copper row 43, second branch row 54, second fixed contact 55, second three station moving contact 56, second three station, finally to second wall bushing 58, receives breaker chamber again; When second three station moving contact 56 is transferred to ground connection position, be connected with second grounding contact 59, wall bushing 58 is to the line-to-ground of breaker chamber side.

With original two bus-bar rooms, compare, saved the material of 42,3 insulating sleeves 22 of 6 bus sockets and 3 connecting copper pipes 23, greatly saved cost; Meanwhile, whole original three position mechanism function of independent operation separately that still keeps.The conjuncted gas-insulated switchgear bus-bar room outward appearance total length in double-bus of the present utility model chamber is 800-1600 millimeter, preferably 1200 millimeters.

Two adjacent cabinets are when spelling cabinet, and between the bus-bar room of every 4 cabinet bodies, the number of times of splicing is directly reduced to 1 time from 3 times between two, has improved the efficiency of on-the-spot spelling cabinet, has reduced because spelling the cabinet Leakage Gas risk that may cause of poor quality and insulation risk.

Although disclose for the purpose of illustration preferred embodiment of the present utility model and accompanying drawing, person skilled in the art, within not departing from the spirit and scope of the utility model and appended claim, can do various replacements, variation and retouching.Therefore, the utility model should not be limited to preferred embodiment and the disclosed content of accompanying drawing, and protection range of the present utility model is as the criterion with the scope that appending claims was defined.
