Fig. 2 is three kinds of distribution modes of parallel pole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model and principle of work are described in further detail.
As shown in Figure 1:
A kind of photovoltaic cell group automatic dust removing control system, comprises photovoltaic cell group (4) and is arranged on transparent panel, polyphase source and the multicircuit switch (1) in photovoltaic cell group (4); Transparent panel surface is provided with the electrode of many parallel distributions, and the number of electrode is the integral multiple of the electrode number of phases, and the parallel pole on each transparent panel is connected with polyphase source by multicircuit switch (1).
Wherein switch is one group of field effect transistor, and the conducting of field effect transistor is by Single-chip Controlling.
Parallel pole distribution mode on transparent panel in photovoltaic cell group (4) has three kinds of modes.
As shown in Figure 2:
Mode one, as shown in Fig. 2 the first from left, parallel pole presses the alternating parallel distribution successively of A, B, C three-phase, forms a plurality of electrodes of integral multiple of 3.Also only can be arranged to the alternating parallel distribution successively of A, B two-phase, form a plurality of electrodes of the integral multiple of 2
