| description | The utility model provides a leakage protecting device for resisting high-frequency interference when starting an electronic fluorescent lamp, comprising a leakage induction circuit, a leakage detecting circuit and a power supply switching unit, wherein the leakage induction circuit is connected with the leakage detecting circuit and used for inducting a leakage signal, converting the current signal into a voltage signal and transmitting the voltage signal to the leakage detecting circuit; and the leakage detecting circuit is used for filtering, amplifying and rectifying the received leakage signal and then obtaining direct-current voltage which is input to the power supply switching unit. The leakage protecting device is characterized in that the leakage detecting circuit is a leakage breaker chip; two voltage input ends of the chip are bridged with a high-frequency absorbing capacitor which is used for shielding high-frequency interference leakage occurring when the electronic fluorescent lamp is started; a |
