The device comprises a circuit board (2), a magnetic core (3) and a hall element (4), wherein the hall element (4) is welded on the circuit board (2); the magnetic core (3) is of an annular structure; an opening is formed on the magnetic core (3) of the annular structure; the hall element (4) is arranged in the opening; the circuit board (2), the magnetic core (3) and the hall element (4) are all mounted in a shell (1); and a through hole corresponding to a central hole of the magnetic core (3) is formed on the shell (1). The current collecting device for photovoltaic confluence provided by the invention is of a low-cost type and has the advantage that the primary input current is completely isolated from the internal circuit.
Description
Technical field
The present invention relates to a kind of current collecting device, especially relate to a kind of current collecting device of photovoltaic on confluxing that be used for.
Background technology
At present; Domestic photovoltaic generation industry development is like a raging fire; To gather used photovoltaic cell current measurement device more single and conflux as photovoltaic; A kind of is to adopt finished product perforated Hall current sensor element, and tested electric current passes the primary side center hole mode on the Hall current sensor element through cable, uses this mode that a plurality of Hall current sensors need be installed in the harvester that confluxes; Open type iron core, (then also needing on iron core around compensating coil when adopting the magnetic balance principle) Hall semiconductor element, external signal modulate circuit all need be used in the Hall current sensor inside of this type; Cause complex structure, volume is bigger, can't realize that the requirement of miniaturization and price are higher; Another kind is direct access type integrated hall sensors, because this class component belongs to integrated circuit, signals collecting and modulate circuit all have been integrated in chip internal; Element-external need not the adapted magnetic core, only needs tested electric current to insert the current input terminal of the Hall element that defines, and just can produce conditioned output voltage signal; This kind mode cost is lower; But because primary current need use the wiring board wire laying mode to introduce, need extra input and output terminal, install inconvenient; And, cause the product overall security to reduce owing to introduced signal one time in the electric wiring.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of current collecting device of photovoltaic on confluxing that be used for that low-cost type that input and internal wiring realize complete electrical isolation is provided once.
The objective of the invention is to realize like this: a kind of current collecting device of photovoltaic on confluxing that be used for; Said device includes wiring board, magnetic core and Hall element; Said Hall element is welded on the wiring board; Said magnetic core is a ring texture, and the magnetic core of said ring texture is provided with an opening, and is provided with a Hall element in this opening.
The present invention is a kind of to be used for the current collecting device of photovoltaic on confluxing, and said wiring board, magnetic core and Hall element all can be installed in the shell, and have the corresponding through hole of center pit of magnetic core on this shell.
The present invention is a kind of to be used for the current collecting device of photovoltaic on confluxing, and the material of said magnetic core is a ferrite.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention uses the integrated form Hall element; Need not outside modulate circuit; The outside is used open type ferrite class magnetic core; Be the photovoltaic current acquisition function based on Hall effect that in a shell, realizes multichannel, its input current and the complete electrical isolation of device internal wiring, cost be low, safe, use FERRITE CORE and magnetic core to need not coiling, simple in structure, easy for installation.
