The shortcomings such as all fault rate is high, built on stilts bus bridge circuit length, to lay difficulty big and be only applicable to upper incoming line low-voltage cabinet,
And the inverter cabinet of photovoltaic industry is all lower wiring patter.
Integrated photovoltaic transformer station is very important in photovoltaic plant, as one of the nucleus equipment of photovoltaic generation,
The conversion efficiency of inverter product, stability and reliability all can the generated energy in appreciable impact power station and investing back
Report.This means that to reach often to spend electricity cost minimum, must use high-tech, high-quality, high performance-price ratio
Innovative product.And homemade goods in the market, generally have that technical merit is low, properties of product are low, steady
The problems such as qualitative difference, scattered distribution.
Utility model content
The purpose of this utility model is to provide a kind of chassis bus duct, for preassembled transformer station low-voltage bus bar
Connect, the especially connection of integrated photovoltaic transformer station low-voltage bus bar, substitute original low-voltage cable and connect.Solve
Cable cost is high, multi-cable to connect shunting uneven fragile, the problem of built on stilts bus bridge circuit length.
To achieve these goals, this utility model provides a kind of chassis bus duct, including chassis bilayer passage
Space, is provided with n root copper bar bus line, bus frame, bus frame support and pyrocondensation insulation sleeve, n in described space
≥3；Described copper bar bus line connection transformer low-pressure side and inverter ac side.
Further, described chassis bilayer channel space is metal-enclosed type structure, and described double-deck passage is empty
Between end face be detachable shrouding, bottom surface is provided with ventilating heat dissipating hole；Described bilayer channel space one end, chassis
Being connected with transformer low voltage bus district, the other end is connected with inverter ac cable connecting area.
Further, described bilayer channel space bottom surface, chassis is provided with ventilating heat dissipating hole, by inverter
The convulsion in portion forms air flow makes copper bar bus line dispel the heat.
Further, described bus duct is linear type or flexure type.
Further, described bus duct is single channel or the dual pathways.
Further, described bus duct also includes zero bus or ground bus.
Effect of the present utility model: integrated photovoltaic transformer station uses chassis bus duct, becomes compared with using cable
This reduction by more than 70%, shortens about 2 meters compared with using built on stilts bus bridge, and operational reliability compares cable
Good, safety attractive in appearance is stronger than bus bridge.Solve integrated photovoltaic transformer station easy for installation, reliable and throw
The advantages such as money is few.Also the condition of necessity is created for layout variation in integrated photovoltaic transformer station.

Description of reference numerals: 1-chassis bilayer channel space, 2-bus frame support, 3-end face, 4-transformator
Low-pressure side, 5-copper bar bus line, 6-bus frame, 7-inverter ac side.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model one chassis bus duct is further described: this example is only used for
This utility model being described rather than limits scope of the present utility model, those skilled in the art are new to this practicality
The amendment of the various equivalent form of values of type belongs to the application claims limited range.
As shown in Figure 1, 2, this utility model provides a kind of chassis bus duct, empty including chassis bilayer passage
Between 1, be provided with in described space n root copper bar bus line 5, bus frame 6, bus frame support 2 and pyrocondensation insulation
Set, n >=3；Described copper bar bus line 5 connection transformer low-pressure side 4 and inverter ac side 7.
Described chassis bilayer channel space 1 is metal-enclosed type structure, the end face of described double-deck channel space
3 is detachable shrouding, and bottom surface is provided with ventilating heat dissipating hole；Described bilayer channel space 1 one end, chassis and change
Depressor low-voltage bus bar district is connected, and the other end is connected with inverter ac cable connecting area or low-voltage cabinet.
Described bilayer channel space 1 bottom surface, chassis is provided with ventilating heat dissipating hole, by the convulsion of inverter internal
Form the heat flowing produced when air flow makes copper bar bus line run to distribute.
Described bus duct can be linear type, it is also possible to be flexure type；Can be single channel (1 road three-phase),
Can also be the dual pathways (2 road three-phase), and zero bus or ground bus can be comprised.
Copper bar bus line adds thermal shrinkable sleeve reinforced insulation performance, and copper bar bus line 5 is fixed on bus frame 6, bus frame
