Delayed protection circuit is mainly composed of the charge and discharge loop (R6, C5), YF1 and the RS flip-flop, relay J3, driver circuit (BG2, BG3) composed of YF2. When it is connected with the power supply, because the voltage on C5 is not mutation, YF1 outputs low. It makes BG2, BG3 conducted, the relay J3 will be pulled in. The load starts to work because the J3-1 is connected to the power supply.
