Abstract
The present disclosure provides an electrostatic protection circuit, a circuit board, and an electrostatic protecting method. The electrostatic protection circuit includes a first relay and a second relay, wherein a control terminal of the first relay and a control terminal of the second relay are configured to be connected to a power supply of a system circuit respectively, and wherein the first relay and the second relay are connected in series between the system circuit and a ground terminal to form a charge release path, and the first relay is switched from an open circuit state to a short circuit state when the system circuit is powered off, and the charge release path is in a turn-on state after the first relay is switched to the short circuit state, thereby releasing an electrostatic charge in the system circuit.
