Description
Technical field
The utility model belongs to the photovoltaic generation applied technical field, and especially a kind of speed is inserted formula waterproof array header box.
Background technology
Traditional energy is reducing day by day, and the harm of environment is become increasingly conspicuous, and the world all invests regenerative resource to sight during this period, and in the regenerative resource, solar energy becomes the focus that people watch attentively with its exclusive advantage.The solar power plant is that of solar energy mainly utilizes mode, the solar power plant mainly is that several solar components are formed certain array by connection in series-parallel, then array is connected with controller (autonomous system contains storage battery) or inverter (grid-connected system), in the time of illumination, solar cell can generate electricity and charge a battery, or direct current is converted to alternating current by inverter, then and to electrical network.
In this process, the wiring of solar components is more loaded down with trivial details, also more complicated.Existing main mode is to utilize pvc pipe threading, adds waterproof junction box in the joint.This technological operation is got up loaded down with trivial details, and fail safe is lower.At first, the anti-recoil diode between the array can't be installed; Secondly, the lightning protection of array can't be installed, and fail safe is low; Once more, joint is too many, stays potential safety hazard.
In addition, if the large solar power station, the wiring meeting is very complicated, increases a lot of amounts of labour, and makes mistakes easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of wiring speed quick, simple to operate to insert formula waterproof array header box.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of speed is inserted formula waterproof array header box, constitute by the control circuit in casing and the casing, wherein control circuit is made of both positive and negative polarity bus-bar, both positive and negative polarity connecting terminal block and circuit breaker, lightning protection device, anti-recoil diode, the electric wire connecting junction of solar components is a series connection form formation group string, be connected in parallel respectively anode and cathode terminals row of the both positive and negative polarity of a plurality of groups of strings realizes that parallel connection confluxes, be connected on the both positive and negative polarity bus-bar side of the positive electrode of each the group string anti-recoil diode of all connecting then.
And the both positive and negative polarity bus-bar connects a circuit breaker, is parallel with lightning protection device on the circuit of circuit breaker.
Advantage of the present utility model and good effect are:
1, this header box adopts the array format wiring, and it is very convenient to operate, and saves time, and reduces the amount of labour.
2, in the array of this header box lightning protection device is installed, has improved fail safe greatly.
3, anti-recoil diode is installed in this header box, has improved systematic function.
4, this header box is the plug-in wiring, and array maintenance, repair in the future are very convenient.
5, the wiring of this header box is neat, and is attractive in appearance.

Fig. 1 is the array wiring schematic diagram of the utility model solar components;
Fig. 2 is circuit theory diagrams of the present utility model;
Fig. 3 is a physical connection schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of speed is inserted formula waterproof array header box, is made of the control circuit in casing 3 and the casing.Control circuit is made of both positive and negative polarity bus-bar 6, both positive and negative polarity connecting terminal block 7 and circuit breaker 4 (K), lightning protection device 5 (B), anti-recoil diode D, the electric wire connecting junction 2 of solar components 1 is series connection form formation group string, the group string can be a plurality of and forms array, and the present embodiment accompanying drawing is depicted as the array of eight group strings; The both positive and negative polarity of all the group strings anode and cathode terminals row that is connected in parallel respectively realizes that parallel connection confluxes, and is connected to then on the both positive and negative polarity bus-bar; Each side of the positive electrode of group string anti-recoil diode D that all connects wherein, can effectively prevent between each group string array counter filling by this recoil diode because voltage is inconsistent, or the electric current of grid side fills to solar array, can prevent that also shade from blocking the hot spot effect of formation.
The both positive and negative polarity bus-bar can be connected to inverter or controller by circuit breaker K, is parallel with lightning protection device B on the circuit of circuit breaker, to improve fail safe.
Operation principle of the present utility model is:
With the solar components formation group string that is together in series, series connection can utilize solar components to be connected with connector between the assembly, and is in parallel then; Can utilize header box to carry out parallel connection the time in parallel confluxes, receives inverter or controller then; Utilize terminal board to carry out wiring, conflux with bronze medal, the side of the positive electrode on each road anti-recoil diode of connecting prevents between each serial array counter the filling because voltage is inconsistent, or the electric current of grid side fills to solar array, can prevent that also shade from blocking the hot spot effect of formation.In wiring, we directly receive electric wire connecting junction on the terminal board of header box, then the electric wire connecting junction of array and the electric wire connecting junction of header box are connected.
