| description | The invention discloses a frequency converter electric leakage protection device and method, and belongs to the technical field of frequency converters. The frequency converter electric leakage protection device comprises a housing which is internally provided with a cavity, and the cavity is used for placing a frequency converter; the electric leakage detection unit is arranged on the shell; the infrared detection unit is arranged on the shell; and the first switch unit is arranged on a line between the frequency converter and the first power supply. And when the electric leakage detection unit detects that the shell is electrified and the infrared detection unit receives the target infrared light, the first switch unit is in an off state.
本申请公开了一种变频器漏电防护装置和方法，属于变频器技术领域。其中，该变频器漏电防护装置包括：壳体，该壳体内具有空腔，该空腔用于放置变频器；漏电检测单元，设置于壳体上；红外检测单元，设置于壳体上；第一开关单元，设置于变频器与第一电源之间的线路上。其中，在漏电检测单元检测到壳体带电、且红外检测单元接收到目标红外光线的情况下，第一开关单元处于断开状态。 |
