| Zusammenfassung: | A cut-off device for electrical equipment judges if the electrical equipment is in normal operating state or standby state by detecting the electric current variation of the electrical equipment so as to control the power supply to supply power to the electrical equipment or not, avoiding the waste of power energy. In addition, It can avoid plug elastic fatigue caused by pulling the plug out to save power energy, which may further leads to the following drawbacks such as loosening of plug, dust accumulation, production of spark, increase of resistance, increase of temperature of contact points of plug and socket, wire insulation deterioration, or even short circuit. |
