| 摘要 |
<p>The invention relates to a safety device (20) between: a photovoltaic panel (4) comprising two electrical terminals (41, 42); and a circuit external to the photovoltaic panel (4) comprising two electrical outputs (31, 32), comprising: a first switch (201) arranged between the electrical terminals (41, 42) and possibly being controlled in order to adopt a first position in which the electrical terminals (41, 42) are connected together, thus short-circuiting the photovoltaic panel (4); a second switch (202) arranged between the electrical outputs (31, 32), which switch can be made to adopt a first position in which the electrical outputs (31, 32) are connected together, thus short-circuiting the external circuit (3); and means (203) for controlling the first and second switches (201, 202), comprising means (2031) for detecting an operating signal produced by the external circuit (3).</p> |
