Abstract
The utility model discloses a zero-line disconnection protector of a voltage-reduction universal self-inspection socket of a capacitor. A zero-line disconnection-protection option switch, safety self-inspection indication lamps and a test button are installed on a single-phase three-pole conjoined plug or a single-phase three-pole socket. When the single-phase three-pole conjoined plug is plugged in the single-phase three-pole socket of a user, a live wire is at a right location if an indication lamp between the live wire and a ground wire and an indication lamp between the live wire and a zero line light at the same time, or else a connection error happens and electric equipment can be used after the removal of the error. The zero-line disconnection protector can protect the electric equipment when the zero line of a supply line breaks off to cause the imbalance of three-phase power and a medium voltage across the zero line and the ground wire rises to cause the cutoff of a leakage protector. The protector has advantages of simple circuit, low cost and convenient operation, and is very practical.
