Abstract

The utility model discloses a large-current MNS outlet cabinet, which is characterized in that two vertical bus processing forms can be adopted. In the first form, the original bus on the outlet cabinet is divided into an upper section of bus and a lower section of bus, and 1300A current can flow through each section of bus; in the second mode, the form of the original bus is not changed, and a copper bar is additionally arranged outside the outlet cabinet. The utility model solves the problem of small distribution of the large-current MNS outlet cabinet, reduces the cost of the large-current MNS outlet cabinet and solves the problem that large-current MNS electric equipment occupies big area.

Description

A kind of big electric current MNS outlet cabinet

Technical field

The utility model relates to a kind of MNS outlet cabinet, is specifically related to a kind of big electric current MNS outlet cabinet.

Background technology

Existing MNS standard outlet cabinet vertical bus is 50 * 30 * 6 L type copper bar, and it is flush-mounted in the flame retardant plastics function wall, and its electric current that can pass through is 1300A-1400A to the maximum.Along with the continuous lifting of the power consumption equipment and the power consumption of big electric current, the MNS outlet cabinet of 2000A has appearred surpassing.50 * 30 * 6 L type copper bar originally obviously can't satisfy 2000A and above electricity consumption requirement, also adopt original little electric current form to occur, certainly will will increase outlet MNS cabinet, if will increase manufacturing cost like this, the space of maintenance cost and power distribution room is strengthened.Land resource for nervous now obviously is not suitable for.

The utility model content

For overcoming deficiency of the prior art, the purpose of this utility model is to provide a kind of big electric current MNS outlet cabinet, and it has solved the little problem of separate unit distribution of MNS, makes the use occasion of MNS more extensive.

In order to solve the problems of the technologies described above the realization above-mentioned purpose, the utility model has been taked following technical scheme:

This outlet cabinet can adopt two kinds of vertical bus processing form:

1) be the segmentation vertical bus, every section vertical bus can pass through electric current 1300A, and total current can be passed through 2600A like this.The form of segmentation vertical bus is: the upper semisection vertical bus has only 800-1000mm, and lower semisection vertical bus length is the length that length overall deducts the upper semisection vertical bus, and concrete bus length is looked the arrangement of outlet drawer, size and purposes and decide.Its concrete processing method is: the upper semisection vertical bus still adopts general MNS outlet form, it still is general type that outlet cabinet vertical bus is connected with main bus bar, be the upwards row of turning over of feature board inlet wire pile crown, be connected with main busbar, and the copper bar specification will adopt bigger form.And the lower semisection vertical bus also is to be the form of upper semisection vertical bus substantially, and it also has a pile crown that is connected with main bus bar, is thus connected on the pile crown turning over one to be connected with main bus bar with copper bar that upper semisection turns over the same specification of row.

Design has avoided elongated vertical bus to limit the electric current that can pass through like this, and the temperature rise phenomenon of having avoided the excessive formation of electric current.

2) be the vertical bus that still adopts general MNS, not disjunction of bus, length still is 1800mm, but will externally add a copper bar again, to satisfy the outlet requirement of 2600A.Its concrete processing method is: the not disjunction of whole vertical bus, but the pile crown that is connected with bus will design two, with with the same specification of vertical bus or bigger copper bar up and down two pile crowns be connected to fall, the bus that re-uses bigger specification is connected with main bus bar.

Take this mode to handle, go out line current and can reach bigger specification, flexibility is higher.

The vertical busbar of the big electric current MNS of the utility model outlet cabinet can pass through the 2600A electric current.Big electric current scheme of electric power such as 9 250A air circuits or 4 630A air circuits can be installed, always go out line current and can reach 2600A.Solved the little problem of separate unit distribution of MNS, made the use occasion of MNS more extensive.

Description of drawings

Below in conjunction with drawings and embodiments the utility model is described in further detail.

Fig. 1 is the utility model one example structure schematic diagram;

Fig. 2 is another example structure schematic diagram of the utility model.

Number in the figure explanation: 1. upper semisection vertical bus, 2. lower semisection vertical bus, 3. copper bar, 4. outlet cabinet.

Embodiment

Embodiment 1:

As shown in Figure 1, a kind of big electric current MNS outlet cabinet is the segmentation vertical bus, and every section vertical bus can pass through electric current 1300A, and total current can be passed through 2600A like this.The form of segmentation vertical bus is: upper semisection bus 1 has only 800-1000mm, and lower semisection vertical bus 2 length are the length that length overall deducts upper semisection vertical bus 1, and concrete bus length is looked the arrangement of outlet drawer, size and purposes and decide.Its concrete processing method is: upper semisection vertical bus 1 still adopts general MNS outlet form, it still is general type that outlet cabinet vertical bus is connected with main bus bar, be the upwards row of turning over of feature board inlet wire pile crown, be connected with main busbar, and the copper bar specification will adopt bigger form.And lower semisection vertical bus 2 also is to be the form of upper semisection vertical bus 1 substantially, and it also has a pile crown that is connected with main bus bar, is thus connected on the pile crown turning over one to be connected with main bus bar with copper bar that upper semisection turns over the same specification of row.

Embodiment 2:

As shown in Figure 2, a kind of big electric current MNS outlet cabinet still adopts the vertical bus of general MNS, not disjunction of bus, and length still is 1800mm, but will externally add a copper bar 3 again, to satisfy the outlet requirement of 2600A.Its concrete processing method is: the not disjunction of whole vertical bus, but the pile crown that is connected with bus will design two, with with the same specification of vertical bus or bigger copper bar 3 up and down two pile crowns be connected to fall, the bus that re-uses bigger specification is connected with main bus bar.

Claims

1. one kind big electric current MNS outlet cabinet, it is characterized in that: the original cashier's office in a shop vertical bus of outlet is segmented into epimere and hypomere vertical bus, and every section vertical bus can pass through electric current 1300A.

2. big electric current MNS outlet cabinet according to claim 1, it is characterized in that: the upper semisection bus has only the 800-1000 millimeter, and the lower semisection bus length is the length that length overall deducts the upper semisection bus.
