The main function of the excavator relay is to control the switching of current within the excavator’s electrical system.
An excavator relay is an electrical control component that operates based on electromagnetic induction and contact action. When the relay coil is energized, it creates a magnetic field that attracts the armature and closes the contacts, thus completing the circuit. When the coil is de-energized, the magnetic field disappears, the armature returns to its original position under the spring’s force, and the contacts open, disconnecting the circuit. This mechanism allows the relay to control the circuit.
Relays are widely used in various control circuits within the electrical system of the excavator, such as starting circuits, lighting circuits, and safety protection circuits. They are responsible for controlling the flow of current to manage different components of the excavator. For example, during startup, the start relay connects the starter motor to the power supply, enabling the excavator to start. When lighting is needed, the lighting relay activates the lighting circuit to provide adequate illumination.
Relays are categorized into types such as current relays, voltage relays, time relays, and thermal relays, each playing a specific role in the excavator’s electrical system, collectively ensuring its proper operation.
