Abstract

The utility model relates to a bus chamber structure of a metal armoured draw-out switch cabinet, which comprises a main bus, a branch bus and a contact box. The utility model is characterized in that the back wall of the main bus is provided with three bus brackets connected with the back wall of the main bus chamber by an isolator in an isolation connection mode; the three main buses are arranged in the main bus chamber from top to bottom in parallel mutually; each main bus is connected with one corresponding bus bracket. The utility model solves the technical problems of weak capability of short-time peak current bearing of the main buses and poor reliability.

Description

The bus-bar room structure of metal armouring draw out switchgear cabinet

Technical field:

The utility model is the switch cubicle about power distribution, particularly about the bus-bar room structure of switch cubicle.

Background technology:

Switch cubicle is as a kind of power distribution equipment, apply to each manufacturing enterprise widely, wherein metal armouring draw out switchgear cabinet is because it can have each combination control room 1 (referring to Fig. 1), breaker chamber 2, cable vault 3, bus-bar room 4 separate units of related components to extract out from the cabinet of switch cubicle, be convenient to maintenance and inspection, be subjected to user's welcome.The bus-bar room 4 of existing metal armouring draw out switchgear cabinet, its three main bus bars are arranged two main bus bars 5 that be arranged in parallel more than 5, following mode of arranging the main bus bar 5 that be arranged in parallel is arranged in the bus-bar room 4, and one side of row's main bus bar 5 has just been reserved the space that three contact boxs 7 are installed naturally down, so arrange, main bus bar 5 can only rely on the branch road bus 6 that links to each other with contact in the contact box 7 unsettled in bus-bar room 4, and the ability that causes it to bear peak current in short-term is low, poor reliability.

Summary of the invention:

The purpose of this utility model is to provide a kind of bus-bar room structure of metal armouring draw out switchgear cabinet, solves main bus bar and bears that peak current ability in short-term is low, the technical problem of poor reliability.

The technical scheme that is that the utility model solves the problems of the technologies described above is as follows:

A kind of bus-bar room structure of metal armouring draw out switchgear cabinet comprises containing main bus bar, branch road bus, contact box, it is characterized in that: be provided with three bus structures that are connected with the insulation of main bus bar chamber rear wall by insulator at this main bus bar chamber rear wall; These three main bus bars are set parallel to each other from top to bottom in that main bus bar is indoor, and each main bus bar bus structure corresponding with connects.

It is characterized in that: these three main bus bars are positioned on the same vertical plane or on the different vertical planes.

The utlity model has following advantage:

1, because the main bus bar vertical arrangement has strengthened the bus-bar room space, improved heat dispersion.

2, set up bus structure, improved the bearing state of main bus bar, it bears in short-term that the ability of peak current is improved, and it is more reliable to work.

3, under the condition that the main bus bar sectional area is waited until mutually, can strengthen the rated current of distribution system.

Fig. 2 is a kind of structural representation of the present utility model.

Fig. 3 be among Fig. 2 A to view (getting) except that roof.

Among the figure:

The 2-of the 1-control room breaker chamber 3-4-of cable vault bus-bar room

5-main bus bar 6-branch road bus 7-contact box 8-wall bushing

9-insulator 10-bus structure

Embodiment:

See also Fig. 2 and shown in Figure 3, bus-bar room 4 of the present utility model comprises three main bus bars 5, three branch road buses 6 and three contact boxs 7.Each main bus bar 5 is continuous with the fixed contact in the corresponding contact box 7 by a branch road bus 6.Contact box 7 is fixed on bus-bar room 4 antethecas below, and they are by the epoxide resin material manufacturing of tool insulation property.Three main bus bars 5 be arranged in parallel in bus-bar room 4 from top to bottom, and the distance that each interval is certain at its cabinet place of stretching out switch cubicle, is provided with the wall bushing 8 of insulation.Bus-bar room 4 rear walls are provided with three bus structures 10, each bus structure 10 and the 5 fixing or supporting connections of a corresponding main bus bar, thus main bus bar 5 firmly is arranged in the bus-bar room 4, improve it and bear the ability of peak current in short-term.Have insulator 9 on this bus structure 10, make bus structure 10 form insulation and be connected, guarantee the safety utilization of electric power requirement with the metal rear wall of bus-bar room 4.

If each bus structure 10 has consistent overall dimension as shown in the figure, then three main bus bars 5 are in bus-bar room 4 on the same vertical plane, and this helps the manufacturing and the installation of product; But also the different length dimension of tool can be arranged respectively, so, 5 of three main bus bars are straggly on different vertical planes before and after bus-bar room 4 in, and are though this layout straggly bring some inconvenience for manufacturing and installation, more favourable to the heat radiation that bus-bar room 4 is interior.

Claims

1, a kind of bus-bar room structure of metal armouring draw out switchgear cabinet comprises containing main bus bar, branch road bus, contact box, it is characterized in that: be provided with three bus structures that are connected with the insulation of main bus bar chamber rear wall by insulator at the female chamber of this master line rear wall; These three main bus bars are set parallel to each other in bus-bar room from top to bottom, and each main bus bar bus structure corresponding with connects.

2, the bus-bar room structure of metal armouring draw out switchgear cabinet according to claim 1 is characterized in that: these three main bus bars are positioned on the same vertical plane or on the different vertical planes.
