Abstract

The utility model discloses a bus in a switch cabinet bus bridge and a switch cabinet. The bus is a double-layer structure formed by bending one piece material, a cross section of the bus is a U-shaped structure. The bus utilizes a double-structure copper bus instead of a common rectangular copper bar, so 10% to 30% materials can be saved while effective areas are identical, assembly is simple and convenient, the bus is applicable to bus bridges over a 1600A level in a switch cabinet industry, the bus has better saving effects when a current level is higher.

Description

Bus in a kind of switch cubicle bus bridge and this switch cubicle

Technical field

The utility model relates to bus and this switch cubicle in a kind of switch cubicle bus bridge, relates to a kind of being folded by a copper sheet particularly and forms, and is double-deck bus, particularly relates to a kind of U-shaped double-deck bus and this switch cubicle of being.

Background technology

Switch cubicle is a kind of electric equipment, and outside line is introduced into master switch in the cabinet, enters branch control switch then, and each needs to arrange by it along separate routes.As instrument, automatic control, the motor magnetic switch, various A.C. contactors etc., what have also establishes hyperbaric chamber and low-pressure chamber switch cubicle, is provided with high voltage bus, and as the power plant etc., what have also is provided with to protecting the low-frequency load reduction of capital equipment.

Along with emerging in large numbers of modernization project facility and equipment, the power consumption of all trades and professions is fast to be increased, the appearance in especially numerous skyscrapers and large-sized workshop workshop, traditional cable as transmission pressure can not meet the demands in big electric current conveying system, and the parallel connection of multiway cable is used to on-the-spot installation connection and brought inconvenience.Bus arises at the historic moment as a kind of novel distribution lead, compare with traditional cable, when carrying, big electric current demonstrates fully its superiority, simultaneously owing to adopted new technology, new technology, contact resistance and the temperature rise of the junction, bus duct both ends of Jiang Diing and separated time mouth splicing position greatly, and in bus duct, used high-quality insulating material, thus improved the security reliability of bus duct, make whole system more perfect.

Bus is formed by many sections, and each segment length is both short and light.Therefore, only need several people just can finish rapidly during installation.Bus has part and the stock of many standards, and the work on the spot time is saved in shipment fast.Its closely " sandwich " structure can reduce electric space, thereby vacate more space as commercial use, as hiring out or as the public place.For cable is installed, then be the work of a difficulty.Because unit cable is often very heavy, installment work needs a lot of people's cooperation, spends the more time just can finish.In addition, be limited by the bending radius of cable, need more installation space.

For traditional cable line, cable can make electrical system extremely complicated, huge, is difficult to safeguard, like this, has just wasted engineering cost and installing space.By using bus duct, can merge some duplexure, and with jack box it is converted into a big bus duct.It can simplify electrical system, obtains the current value low than multi cord.Therefore saved the cost of engineering, and be easy to safeguard.

Plain conductor or the twisted wire of rectangle or circular cross-section mostly adopted in the connection of voltage power distribution equipments at different levels in electric substation, and being connected of electric equipment such as transformer, switch cubicle and corresponding power distribution equipment, and this is referred to as bus.The effect of bus is to compile, distribute and transmit electric energy.Because bus is in operation, and has huge electric current to pass through, and during short circuit, is bearing very big heating and dynamo-electric effect, therefore, must reasonably select for use bus material, cross sectional shape and sectional area to meet the requirement of safety and economic operation.

When the cross-sectional area of bus was identical, the girth of rectangular bus bar was longer than circular bus, its good heat dissipation effect, and cooling condition is good, and at one end allows under the heating-up temperature, and the electric current that rectangular bus bar passes through is bigger than circular bus.The skin effect of circular bus is stronger, and rectangular bus bar is more even.Bus in the existing switch cubicle bus bridge adopts rectangular copper bar to be spliced, and adopts three copper bars to splice usually, and this structure is not easy to assembling, and the waste raw material.

The utility model content

Main purpose of the present utility model is to provide a kind of have double-deck bus and this switch cubicle, to solve the above-mentioned problems in the prior art.

The technical scheme that the utility model provides is as follows:

Bus in a kind of switch cubicle bus bridge is characterized in that: this bus forms double-decker by sheet material bending, and its cross section is the U font.

In a preferred embodiment, sheet material curves the U font earlier, and two arms of this U font bend applying arm and base plate more respectively.

In a preferred embodiment, the bending of described U font two arms is bending to the inside or bending laterally.

In a preferred embodiment, the space is left in base plate intersection in both sides copper sheet bending back.

In a preferred embodiment, internal layer and the skin of U-shaped bottom are provided with the plurality of fixed hole.

A kind of switch cubicle, it has the bus in aforesaid a kind of switch cubicle bus bridge.

The technical program is compared with background technology, and it has following advantage:

1, cross-sectional area of the present utility model is U-shaped, utilizes " skin effect ", under the identical situation of net sectional area, adopts double-deck bus materials to save 10%-30% than traditional bus.

2, traditional bus is spliced by three copper bars usually, and the bus in this programme only is an independent material, and is not only convenient for assembly but also reduced handling of goods and materials.
