摘要： A photovoltaic (PV) power system is disclosed that includes hybrid DC contactors corresponding to each of a plurality of PV strings, with each hybrid DC contactor having main contacts, a solid state switching unit positioned in parallel with the main contacts, and sensors configured to measure a voltage and current on respective PV strings. A controller is provided in the PV power system that is configured to receive voltage and current data on the PV strings, detect a fault condition on a respective PV string based on the voltage and current data, cause the main contacts of a respective hybrid DC contactor to remain closed on each PV string for which a fault condition is detected, and cause the main contacts of a respective hybrid DC contactor to open on each PV string for which no fault condition is detected, so as to clear the fault condition.

摘要： An electrical switching apparatus (2) includes two arc runners (4,6), two contacts (8,10) in electrical communication with the respective runners, a movable contact (12) having two portions (14,16) respectively cooperating with the contacts to provide closed and open contact positions, and two arc chambers (18,20) each including two ends (22;30,24;32), a longitudinal axis (26;34) therebetween, and arc plates (28;36) between the ends. A magnet assembly (40) cooperates with the arc chambers (18,20) to establish a generally unidirectional magnetic field (42) normal to the axes, normal to a first direction (44) of a first arc (46) between one contact (8) and the first portion (14) as it moves away from the closed toward the open contact position, and normal to an opposite second direction (48) of a second arc (50) between the other contact (10) and the second portion (16) as it moves away from the closed toward the open contact position. The magnetic field causes one arc to enter one arc chamber depending upon current flow direction between the contacts.
