Description

A kind of method for effectively improving distributed power source grid connection efficiency
Technical field
The present invention relates to a kind of operating method, and in particular to a kind of method for effectively improving distributed power source grid connection efficiency.
Background technology
State Grid Corporation of China has opened one for the distributed photovoltaic power generation project accessed with 220V and 380V voltage class It is bonded enter green channel, main purpose be exactly in order to realize the accessible rapid combination of small distributed photo-voltaic power supply, it is grid-connected to set Standby is the grid-connected core content of distributed power source, by Field Research, finds existing synchronizing mode largely still in use point Formula grid-connection device is dissipated, i.e. electricity box, meter, air switch, disconnecting link etc. is purchased respectively, and equipment unifies installation afterwards in place, from current Scattered grid-connection device operation actual conditions analysis, it is primarily present following three aspect and compares distinct issues.When grid-connection device compared with It is scattered, equipment operation brings many probability for jeopardizing safe risk point, increasing influence security incident generation;Second, do not have Special power distribution network distinguishes the different equipment blocking of property right, causes actual motion difficult in maintenance unintelligible with property interface;Three Be various kinds of equipment to be waited in place after scene carry out grid-connection device transformation, distribution box interim processing, so as to greatly reduce point Cloth power network grid connection efficiency, backward synchronizing mode be difficult in adapt to Guo Wang companies implementation one it is bonded enter Advanced Idea.
The content of the invention
It is an object of the invention to provide a kind of method for effectively improving distributed power source grid connection efficiency, this method makes grid-connected mistake Journey is extremely simple, fully achieves the function of " plug and play ".
The present invention is achieved through the following technical solutions:
A kind of method for effectively improving distributed power source grid connection efficiency, comprises the following steps:
The first step, the grid-connected special distribution box of distributed power source is fixedly mounted on grid-connected position;
Second step, using the wire clamp on the grid-connected special distribution box of distributed power source, by entrance line, user's line and examination gauge table Quick connection, is completed grid-connected.
Further, the grid-connected special distribution box of described distributed power source includes the first disconnecting link, grid-connected gauge table, grid-connected open circuit Device and examination gauge table, the two-way circuit of entrance line are connected to one end of the first disconnecting link, and the first disconnecting link other end connects grid-connected meter Scale, grid-connected gauge table connect user's line by grid-connected breaker;Described examination gauge table is connected on user's line.
Further, described two-way circuit is connected to the both ends of disconnecting link by insulating properties copper-aluminium transition Special wire-clip.
Further, described two-way circuit is fixed on grid-connected breaker both ends by copper cash Special fork shaped cable clamp.
Further, described user's line includes the second disconnecting link, photo-voltaic power supply, inverter and some breakers, wherein grid-connected Breaker connects examination gauge table by the second disconnecting link, while connection breaker is connected with customer charge respectively;Photo-voltaic power supply leads to Inverter and breaker are crossed as examination gauge table power supply.
The beneficial effects of the invention are as follows:
First, optimize operation flow, shorten the grid-connected application time.Utilize the reality of completed distributed power source grid-connection comprehensive distribution box Body equipment, the functions of the equipments of the interim assembling grid-connection device link in scene, realization and network users plug and play are reduced, are greatly improved simultaneously Net access efficiency and new energy access service are horizontal.
2nd, device configuration standard, clarification of property rights separation, convenience is created for production maintenance.Utilize distributed electrical Source grid-connection comprehensive distribution box, unitized, the standardization of grid entry point internal electric equipment are realized, is created for later stage operation maintenance very big Convenience.By using distributed power source grid-connection comprehensive distribution box, become apparent from clearly, just with user's property right separation position Distinguish and distinguish in user and electric company personnel.
3rd, in special distribution box, greatly reducing influences what security incident occurred for all standard of electrical apparatusization configurations Probability, it is ensured that equipment safety operation.
Brief description of the drawings
Fig. 1 is the grid-connected special distribution box internal electric connection diagram of the present invention and electrical equipment combination diagram.
Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
The present invention is a kind of method for effectively improving distributed power source grid connection efficiency, and this method uses copper cash Special fork molded line Folder 8 quickly connects entrance line, user's line and examination gauge table, completes grid-connected.This method is first by the four of special distribution box 7 Individual part:First disconnecting link 2, grid-connected gauge table 5, grid-connected breaker 3 and examination gauge table 6 are arranged on grid-connected position, then pass through Insulating properties fixed screw 4 is fixed on special distribution box 7.The two-way circuit of entrance line passes through insulating properties copper-aluminium transition Special wire-clip 1 is fixed on one end of the first disconnecting link 2, and the other end of the first disconnecting link 2 is connected with grid-connected gauge table 5, and grid-connected gauge table 5 is special by copper cash It is connected to forked type wire clamp 8 on grid-connected breaker 3, and connects user's line 9 in the same manner.Grid-connected breaker 3 is connected to Customer charge 95 and examination gauge table 6 in user's line 9,6 are provided with the second disconnecting link between grid-connected breaker 3 and examination gauge table 91, breaker 92 is provided between customer charge 95 and grid-connected breaker 3, photovoltaic electric, 94 are by inverter 93 and breaker 92 Examination gauge table 6 is powered.
