Connect and be incorporated into the power networks, there is the generating efficiency of higher and more preferable environmental-protecting performance, at present country's photovoltaic exchange distribution control box, be mostly
Centralization exchanges grid-connected design, and single outlet, distribution is dumb to be unsuitable for small distributed pv grid-connected plant, roof, mountain
The demand of ground hills photovoltaic plant, may result in when a certain square formation or inverter break down it is overall out of service, to electricity
The power quality and safety and stability of net play undesirable influence.
The content of the invention
The defects of the utility model is in order to make up the prior art, there is provided a kind of distribution is flexible, it is low to install and use cost
Distributed photovoltaic exchanges distribution control box.
The utility model is achieved by the following technical solution：
A kind of distributed photovoltaic exchanges distribution control box, including babinet, is provided with installation riser in the babinet, its feature
It is that no fuse chopper switch is installed in the installation riser, below the no fuse chopper switch from left to right successively side by side
Surge Protector, Surge Protector switch and Self-recover overvoltage-undervoltage protector are installed, wherein being accessed without fuse chopper switch public
Power grid inlet wire, the output terminal without fuse chopper switch is accessed after Surge Protector switch is in parallel with Self-recover overvoltage-undervoltage protector,
The output terminal connection inverter output end of the Self-recover overvoltage-undervoltage protector, the Surge Protector switch access surge protection
The input terminal of device, the output head grounding row of the Surge Protector.
Rank describedly below Surge Protector.
The Self-recover overvoltage-undervoltage protector sets multiple, a Self-recover overvoltage-undervoltage guarantor according to the quantity of string formation inverter
The supporting inverter of device is protected, it is parallel with one another between all Self-recover overvoltage-undervoltage protectors.
The beneficial effects of the utility model are：
The utility model can be equipped with multiple power supply units, and converge multiple inverter currents, will generally exchange distribution control box
Near inverter, the distance of inverter AC line is substantially shorter, reduces direct current line loss, improves client's income, it compares
Conveniently apply in family's photovoltaic power station, the photovoltaic plant small-sized especially suitable for roof, ground, multiple-unit is flexibly matched somebody with somebody
Electricity, has very high practicality, can meet different power demands, and free configuration is carried out according to power demands and user demand,
Therefore there is very strong expansion, the utility model will not because of a certain square formation either inverter damage or failure and integrally stop
Only run, play the role of energetically to the power quality and safety and stability of power grid.
Brief description of the drawings
The utility model will be further described below with reference to the accompanying drawings：
Fig. 1 is the main structure diagram of the utility model；
Fig. 2 is the attachment structure schematic diagram of the utility model.
In figure, 1 babinet, 2 installation risers, 3 public electric wire net inlet wires, 4 without fuse chopper switch, 5 Surge Protectors, 6 surges
Protector switchs, 7 Self-recover overvoltage-undervoltage protectors, 8 inverter output ends, 9 ground row.
Embodiment
Attached drawing is specific embodiment of the utility model.As shown in Figure 1 and Figure 2, this kind of distributed photovoltaic exchange control distribution
Case, including babinet 1, babinet 1 is with cover, and lid can be dismantled, and is provided with installation riser 2 in babinet 1, among 2 top of installation riser
Position is provided with no fuse chopper switch 4, the no lower section of fuse chopper switch 4 be from left to right mounted side by side successively Surge Protector 5,
Surge Protector switch 6 and Self-recover overvoltage-undervoltage protector 7, wherein the access public electric wire net of the input terminal without fuse chopper switch 4
Inlet wire 3, the output terminal without fuse chopper switch 4 is accessed after Surge Protector switch 6 is in parallel with Self-recover overvoltage-undervoltage protector 7,
The output terminal connection inverter output end 8 of Self-recover overvoltage-undervoltage protector 7,6 access Surge Protector 5 of Surge Protector switch
Input terminal, the output head grounding row 9 of Surge Protector 5.Ground row 9 is positioned at the lower section of Surge Protector 5.During installation, inverter input
Tie-in line is held to access self-resetting type mistake by the external line interface of distribution box quoted from photovoltaic solar component, the triple line of inverter output
Pressure-failure protector leading-out terminal, electric energy meter is accessed by no 4 input terminal of fuse chopper switch by distribution box by public electric wire net inlet wire
It is connected to the grid.
Self-recover overvoltage-undervoltage protector can be had according to the quantity of string formation inverter it is multiple, it is parallel with one another between them.
When, because when extraneous interference produces peak current or voltage suddenly, Surge Protector can be extremely short in circuit
Conducting shunting in time, so as to avoid infringement of the surge to other equipment in circuit.Surge Protector, fully ensures that power supply unit
Circuit safety in operation.
When grid maintenance or other reasons have a power failure, Self-recover overvoltage-undervoltage protector detects under-voltage, can be in and protect
Off-state is protected, ensures service personnel's safety, power transmission is normal, and Self-recover overvoltage-undervoltage protector detects voltage when grid maintenance finishes
Normally, automatic reclosing, ensures client's income.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art.
