Charging Pile Relay Introduce:
The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
What is the difference between a DC relay and an AC relay?
Low-voltage relays are directly distinguished by control current. DC control is called DC relay, and AC control is called AC relay., but also to be distinguished by the contact when the contact is direct current, the direct current is divided into positive and negative poles, and the generated arc is stable in the same direction so that the magnetic blowing process is used to quickly extinguish the arc, while the contact adopts the magnetic blowing arc extinguishing process for direct current The relay when the contact communicates, the AC has no polarity, and the arc and direction generated are weak and self-extinguishing and unstable. The AC relay can be made by adopting the anti-arc leakage process.
What can relays and contactors do?
1. The relay can remotely connect and disconnect the circuit in the circuit to realize the remote switch function
2. Switch the current line by on-off to realize the function of multi-line mutual switching
3. Realize multi-device sharing line with a multi-line switching function, so as to realize equipment miniaturization
4. Form an automatic control circuit with other components
5. Real-time detection and monitoring security mechanism with other components
6. Cooperate with the system to prevent electric shock, fire, equipment damage, and other automatic cut-off protection
7. Realize the industrialization of automation8. The relay is the core component in the control circuit and the core component of the new energy vehicle.
