Abstract
The utility model discloses a detection device for a solar energy battery component, which comprises a voltmeter, an ammeter with an adjustable resistance and a control module, wherein the voltmeter, the ammeter and the control module are respectively bridged between an anode and a cathode of the detected solar energy battery component; the control module comprises a resistance, a PNP (Precision Navigation Processor) type triode and a three-phase solid relay; the resistance is connected between the anode of the detected solar energy battery component and a base electrode of the PNP type triode; the three-phase solid relay is connected with a collecting electrode of the PNP type triode in series; and an emitting electrode of the PNP type triode is connected with the cathode of the detected solar energy battery component. As the detection device adopts the switching characteristic of the triode, the detection requirements of the solar energy battery component can be met only through a small quantity of devices, so that the realization cost of the circuit is greatly reduced, and meanwhile, the operation is convenient.
Description
Technical field
The utility model relates to a kind of detection control technology of solar module, more particularly, relates to a kind of pick-up unit of solar module.
Background technology
In the testing process of solar module, need detect technical parameters such as the voltage of solar module, electric currents.As shown in Figure 1,, make after normally opened contact KA3_1, KA3_2, KA3_3 and the KA3_4 closure of low-voltage relay by start button SB1 control low-voltage relay KA3, the coil conducting of three-phase solid-state relay SSR, sunlamp LA lights in the control chart 2; Switch between low-voltage relay KA1 and KA2 by rotary switch SB3 then, control voltage table 8 and reometer 7 and respectively voltage, the electric current of solar module are detected.Adjustable resistance R
LBe the load when detecting voltage and current, can disconnect the relevant detection circuit by stop button SB2 after detection finishes.Though detection mode of the prior art can satisfy the detection requirement of solar module, the operating efficiency of this detection mode is low, the cost height that circuit is realized, and circuit is also comparatively complicated simultaneously.
Summary of the invention
Realize the defective that cost height, while circuit are also comparatively complicated at the testing circuit of the solar module that exists in the prior art, the pick-up unit that the purpose of this invention is to provide a kind of solar module is to realize low cost, easy and simple to handle solar module to be detected.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of pick-up unit of solar module, comprise voltage table, have the reometer and the control module of adjustable resistance, described voltage table, reometer and control module are connected across respectively between the positive and negative electrode of detected solar module, described control module comprises resistance, positive-negative-positive triode and three-phase solid-state relay, and described resistance string is connected between the base stage of the positive pole of detected solar module and positive-negative-positive triode; Described three-phase solid-state relay is serially connected in the collector of positive-negative-positive triode; The emitter of described positive-negative-positive triode is connected with the negative pole of detected solar module.
The Standard resistance range of described resistance is preferably 20K Ω～40 K Ω.
The Standard resistance range of described adjustable resistance is preferably 0～200 Ω.
Compared with prior art, the pick-up unit of solar module of the present utility model is to power to triode by detected solar module, makes the saturated biasing of triode, and causes the conducting of three-phase solid-state relay and control sunlamp and light.Because the utility model has adopted the switching characteristic of triode, therefore, only need just can satisfy the detection requirement of solar module with very a spot of device, and adopt above-mentioned device cost to be significantly less than the cost of a plurality of low-voltage relay of the prior art and button, the cost that circuit is realized reduces significantly, circuit is also very simple simultaneously, operates also very easy.As further improvement, the Standard resistance range of resistance is selected in 20K Ω～40 K Ω, can prevent that like this triode is breakdown.

Fig. 1 is the principle schematic of the control section that solar module detects in the prior art;
Fig. 2 is the principle schematic of the illumination part that solar module detects in the prior art;
Fig. 3 is the circuit diagram of the pick-up unit of a kind of solar module of the present utility model.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Figure 3: the pick-up unit of a kind of solar module that the utility model provides, comprise voltage table 11, have reometer 12 and the control module of adjustable resistance R1, voltage table 11, reometer 12 and control module are connected across respectively between the positive and negative electrode of detected solar module, described control module comprises resistance R 2, positive-negative-positive triode VT1 and three-phase solid-state relay SSR1, and resistance R 2 is serially connected between the base stage of the positive pole of detected solar module and positive-negative-positive triode VT1; Three-phase solid-state relay SSR1 is serially connected in the collector of positive-negative-positive triode VT1; The emitter of positive-negative-positive triode VT1 is connected with the negative pole of detected solar module.Because solar panel can absorb sunshine and heat produces direct current, therefore when needs detect, give positive-negative-positive triode VT1 power supply by detected solar module, make its saturated biasing, make the solid-state SSR1 of three-phase get electric and light sunlamp with this, just can directly detect the voltage and current of solar module like that, very convenient.Breakdown in order to prevent triode, the Standard resistance range of resistance R 2 gets final product between 20K Ω～40 K Ω.Adjustable resistance R1 is a slide rheostat, a load when detecting electric current, and its resistance is adjustable, Standard resistance range can mate the various parameter requests of manufacturing enterprise when solar module is detected like this between 0～200 Ω.The realization cost of this testing circuit is low, and the application on equipment is also very convenient.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the purpose of this utility model, and be not with opposing qualification of the present utility model, as long as in essential scope of the present utility model, all will drop in the scope of claim of the present utility model variation, the modification of the above embodiment.
