Control system of an electromagnetic relay and electromagnetic relay

An electromagnetic relay, comprising a control system, wherein the control system comprises:

• an electromagnet coil;
• a first resistor;
• and
• a first voltage control element, wherein a first terminal of the electromagnet coil is connected to a first terminal of a first power circuit through the first resistor, a second terminal of the electromagnet coil is connected to a second terminal of the first power circuit, the first voltage control element is connected in parallel to the electromagnet coil, the first voltage control element is configured to control magnitude of a voltage across the electromagnet coil, so that force to which armature iron is subjected gradually changes, a rated voltage across the electromagnet coil satisfies a formula:
• U=R/(R+R1)*U1, and U denotes the rated voltage across the electromagnet coil, R denotes an internal resistance of the electromagnet coil, R1 denotes a resistance value of the first resistor, and U1 denotes a voltage of the first power circuit.
