Description

A kind of Novel photovoltaic inverter and box type transformer busbar attachment structure

Technical field

This utility model relates to a kind of Novel photovoltaic inverter and box type transformer busbar attachment structure, belongs to photovoltaic electric power Field of engineering technology.

Background technology

Development photovoltaic generation is the needs of social development.This viewpoint has become the common recognition of people, and the Chinese government is Clearly propose " actively to develop the new and renewable sources of energies such as wind energy, solar energy, underground heat ".On January 1st, 2006 is formally effective " People's Republic of China's Renewable Energy Law " in explicitly point out, the exploitation of regenerative resource are classified as the energy and send out by country The pioneer field of exhibition, develops total amount target by formulating regenerative resource and takes corresponding measure, promoting regenerative resource The foundation in market and development.Country encourages and supports that regenerative resource is generated electricity by way of merging two or more grid systems.

As important component part in photovoltaic project, the photovoltaic DC-to-AC converter of the most domestic photovoltaic generation project and box change Depressor almost all uses the mode of outlet under cable to connect, and this connected mode walks cable radical relatively on basis and underground Many, bring a lot of inconvenience to the construction and installation of engineering and later stage operation maintenance.For this situation, research one construction is succinct, Easy to maintenance and easy popularization connection type is extremely necessary.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of Novel photovoltaic inverter female with box type transformer Row's attachment structure.

To achieve these goals, the technical solution adopted in the utility model is as follows:

A kind of Novel photovoltaic inverter and box type transformer busbar attachment structure, this structure includes transformator outlet casing tube, It is placed in transformer-cabinet top；Photovoltaic DC-to-AC converter sleeve pipe, is placed in photovoltaic DC-to-AC converter casing top；Described transformator outlet casing tube with Photovoltaic DC-to-AC converter cannula tip is respectively mounted binding post, two described binding posts respectively be flexible coupling with bolts, Installing hard busbar between being flexible coupling described in two, the interlude of described hard busbar by support insulator and is placed on support insulator The transition gold utensil of end supports and connects, to ensure the safe distance over the ground of conductor.

Further, described hard busbar can bend according to transformator is different from the height of photovoltaic DC-to-AC converter.

Further, it is flexible coupling described in and hard busbar is bolted.

Further, described hard busbar is aluminium bus array.

The beneficial effects of the utility model:

Hard busbar attachment structure described in the utility model construction is simple, easy to maintenance.Outlet connection side under more normal cable Formula, on hard busbar of the present utility model, outlet connected mode is meeting conductor current-carrying capacity and dynamic and thermal stability while, uses price low Honest and clean aluminium bus array replaces the Copper core power cable that price is higher, and radius of turn when being not required to consider cable laying, for inversion Device and case become compact Layout provides premise, can reduce floor space, reduces construction costs, it is thus achieved that certain economic benefit, and There is construction technology easy, the advantages such as Climatic Effects is little, and trouble point is less, and later maintenance workload is little.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.

As it is shown in figure 1, a kind of Novel photovoltaic inverter and box type transformer busbar attachment structure, use equipment top sleeve pipe Outlet method, this attachment structure includes transformator outlet casing tube 1, is placed in transformator 8 casing top；Photovoltaic DC-to-AC converter sleeve pipe 2, puts In photovoltaic DC-to-AC converter 9 casing top；Described transformator outlet casing tube 1 is respectively mounted terminals with photovoltaic DC-to-AC converter sleeve pipe 2 top Son 3, two described binding posts 3 respectively be flexible coupling 4 with bolts, be flexible coupling between 4 described in two and hard busbar be installed 5, the interlude of described hard busbar 5 is by support insulator 6 and is placed in the transition gold utensil 7 of support insulator 6 upper end and supports connection, with Ensure the safe distance over the ground of conductor.

Described hard busbar 5 can bend according to transformator 8 is different from the height of photovoltaic DC-to-AC converter 9.

Described be flexible coupling 4 be bolted with hard busbar 5.

Described hard busbar 5 is aluminium bus array.

Above-described embodiment uses conventional 2 × 500kW inverter supporting 1MVA box type transformer, and normal cable connected mode is every Platform inverter needs 4, and 2 need 8 cross sections altogether is 3 × 150mm²Copper core power cable connects, empty in narrow and small foundation bottom Walking multi-cable between, workmen operates inconvenience, as stiff in north of china in winter low temperature environment cable, is less susceptible to execute Work and later maintenance.The hard busbar attachment structure using the present embodiment can avoid this drawback, every inverter only to need 3 completely Root, 2 aluminium bus arrays needing 6 a size of 63 × 8 (mm × mm) altogether can meet requirement.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
