Start-up protection method and device for commissioning of electric equipment

The invention discloses a start-up protection method and a start-up protection device for commissioning of electric equipment. A start-up protection device 2n for the current setting, delay and execution of the electric equipment is adopted; an A phase current relay, a B phase current relay, a C phase current relay and a D phase zero sequence current relay which are adopted by setting currents are used for setting the currents of the electric equipment; logic current values for commissioning is set to be more than or equal to 1; current signals of which the set logic current values are more than or equal to 1 are delayed; the delayed current signals are transmitted to a trip executing device; the trip executing device makes platens of a first group of trip outlets LP1 and a second group of trip outlets LP2 of a protection screen control loop of the electric equipment simultaneously input by using an execution relay so as to protect the protection screen control loop. The start-up protection ...
