Abstract

The invention relates to a main circuit structure of a laminated bus. The main circuit structure comprises a capacitor battery DC laminated bus and a power unit DC laminated bus, wherein the two buses are connected. The power unit DC laminated bus is vertical to the capacitor battery DC laminated bus. The capacitor battery DC laminated bus is composed of at least two blocks. The two blocks are communicated through a positive level copper bar and a negative level copper bar. The main circuit layout structure of the laminated bus not only increases the capacitivity, but also meets the requirements on the inner space of a cabinet.

Description

A kind of main circuit structure of laminated bus

Technical field

The application relates to a kind of laminated bus arrangement.

Background technology

Photovoltaic/wind power grid-connected generating technology is the important component part of renewable energy technologies development, and also obtain tremendous development in recent years, portion of techniques achieves commercialization, but also comes with some shortcomings.Particularly in the application of high-power blower unsteady flow device power supply, also deficiency is there is in the main circuit structure layout of current three-phase individual plies bus, the mode that capacitance pool direct current laminated bus and power cell direct current laminated bus side are arranged in front and back in rack at present, like this to the limited amount system of electric capacity, because the degree of depth of rack is restricted, so have strict control to the size of electric capacity.

Summary of the invention

The application, for the deficiencies in the prior art, designs and develops out a kind ofly can make electric capacity increasing number, and meets the laminated bus main circuit layout structure of space requirement in rack.

The application is achieved through the following technical solutions:

A main circuit structure for laminated bus, comprise capacitance pool direct current laminated bus and the connection of power cell direct current laminated bus, described capacitance pool direct current laminated bus and plane-parallel are arranged.

A main circuit structure for laminated bus, described power cell direct current laminated bus is arranged perpendicular to capacitance pool direct current laminated bus.

A main circuit structure for laminated bus, described power cell direct current laminated bus perpendicular to capacitance pool direct current laminated bus, and is parallel to the setting of power cabinet left side plate.

A main circuit structure for laminated bus, described capacitance pool DC side laminated bus is formed by least two pieces, and two pieces are communicated with respectively by positive and negative level copper bar.

The application, by changing into setting up and down by the connection of capacitance pool direct current laminated bus and power cell direct current laminated bus, takes full advantage of the height in space in rack, increases the quantity of electric capacity in the scope that can allow in cabinet space like this.And the height dimension of electric capacity can be unrestricted, be conducive to the general of electric capacity.Capacitance pool DC side laminated bus is formed by least two pieces, and is communicated with respectively by positive and negative level copper bar.Be conducive to the making of capacitance pool DC side laminated bus like this, make installation reliable.

Accompanying drawing explanation

Fig. 1 is laminated bus main circuit structure schematic diagram in power cabinet.

Embodiment

The application's capacitance pool direct current laminated bus 3 and plane-parallel are arranged.Power cell direct current laminated bus 2 perpendicular to capacitance pool direct current laminated bus 3, and is parallel to power cabinet left side plate 1 and arranges.Capacitance pool DC side laminated bus 3 is formed by two pieces, and two pieces are communicated with respectively by positive and negative level copper bar.The application, by changing into setting up and down by capacitance pool direct current laminated bus 3 and the connection of power cell direct current laminated bus 2, takes full advantage of the height in space in rack, increases the quantity of electric capacity in the scope that can allow in cabinet space like this.And the height dimension of electric capacity can be unrestricted, be conducive to the general of electric capacity.
