Abstract
The invention provides an anti-electric-shock fan starting device and belongs to the field of fan power supply protection devices. The device comprises a fan and is provided with a contactor and an open-phase phase sequence protector, a three-phase power source end of the fan is connected to a power source through three normally-opened contacts of the contactor, three detection ends of the open-phase phase sequence protector are connected to a three-phase power source, a power source connection point of the open-phase phase sequence protector is connected to any phase of power source, normally-closed connection points of the open-phase phase sequence protector are connected with one end of a non-self-locking key and one end of a fourth normally-opened contact of the contactor through a self-locking key, and the other end of the non-self-locking key and the other end of the fourth normally-opened contact of the contactor are connected to another phase of power source through a coil of the contactor. The device protects workers against electric shocks, can detect whether the power source misses phases and can provide timely protection.
