The utility model content
The technical problem that the utility model solved is to provide a kind of solar electric power supply system of novel lightning protection, to solve the shortcoming and deficiency in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of novel lightning protection solar electric power supply system; comprise solar photovoltaic cell panel; power-supply controller of electric; storage battery; inverter; and the lightning protection protective system that is in parallel with solar photovoltaic cell panel; it is characterized in that; described lightning protection protective system is formed in parallel by two or more anti-lightening protectors; described anti-lightening protector comprises two varistors; two gas discharge tubes and a thermistor; two varistors connect the positive pole and the negative pole of solar photovoltaic cell panel respectively; each varistor gas discharge tube of connecting respectively; be in series with thermistor after described two gas discharge tube parallel connections, described thermistor connects earth terminal.Described varistor is band protection votage limit type varistor, and described gas discharge tube is the switching mode gas discharge tube.
Operation principle of the present utility model is: when solar photovoltaic cell panel was struck by lightning non-normal working, varistor in the anti-lightening protector and gas discharge tube can be opened rapidly to hold over the ground and carry out current drain; Do not produce if having the lightning induction electric current because of Voltage unbalance or by-pass line, then the thermistor in the bypass circuit can disconnect rapidly, prevent from bypass circuit is caused the electric current counterattack and circuit is damaged because of thunder resisting equipment, thus the protection subsequent conditioning circuit.
Beneficial effect: the utility model has not only strengthened lightning protection effect; and carry out system protection from lightning protection itself; thereby the infringement and the destruction to solar power system self of having reduced the defective of lightning protection accident or lightning-protection system itself and having caused drop to the influence of system's circulation minimum from the characteristics of system itself.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete accompanying drawing, further set forth the utility model:
Embodiment 1: as shown in Figure 1, a kind of novel lightning protection solar electric power supply system comprises solar photovoltaic cell panel 1, lightning protection protective system 2, power-supply controller of electric 3, storage battery 4, inverter 5, and lightning protection protective system 2 is in parallel with solar photovoltaic cell panel 1.
Storage battery adopts lead acid accumulator.Power-supply controller of electric is core control part with the microprocessor, to detect voltage inspection value or current value in real time, realize the switching between the two of solar photovoltaic cell panel, storage battery by the microprocessor driven switch: if solar photovoltaic cell panel supply power voltage or electric current adopt the solar photovoltaic cell panel power supply when estimating voltage or current value, if solar photovoltaic cell panel supply power voltage or electric current stop to adopt the solar photovoltaic cell panel power supply when estimating voltage or current value, and switch to storage battery power supply by solar powered power-supply controller of electric.
Embodiment 2: as shown in Figure 2; lightning protection protective system is formed in parallel by two or more anti-lightening protectors; each anti-lightening protector includes two varistors 21, two gas discharge tubes 22 and thermistors 23; two varistors connect the positive pole and the negative pole of solar photovoltaic cell panel respectively; two varistors gas discharge tube of connecting respectively; be in series with thermistor after described two gas discharge tube parallel connections, described thermistor connects earth terminal.Described varistor is band protection votage limit type varistor, and described gas discharge tube is the switching mode gas discharge tube.
Present embodiment selects for use thermistor 23 to protect, thermistor PTC relevant parameter: maximum voltage U
