leakage circuit breaker
leakage circuit breaker is commonly known as leakage open, and the national standard symbol is QF. A switch that automatically opens when the leakage current in a circuit exceeds a predetermined value. The leakage circuit breaker is used to prevent personal electric shock, and also has short circuit protection and overload protection functions. The national standard symbol of
circuit breaker
circuit breaker is QF. The current in the circuit exceeds the rated value of the automatic action of the switch, with overload protection and short circuit protection function.
fuse
fuse national standard symbol is FU. When the current in the circuit is large, the fuse blows, the circuit is disconnected, and the electrical appliance stops working, which plays a role in protecting the circuit.
contactor
contactor national standard symbol is KM, is a low-voltage control electrical appliances. As an executive element, it is used to connect, break the line, or frequently control the operation of equipment such as motors. The national standard symbol of
relay
relay is KA, which is an "automatic switch" that uses a smaller current to control a larger current ". Therefore, it plays the role of automatic adjustment, safety protection and conversion circuit in the circuit.
thermal relay
thermal relay national standard symbol is FR. The working principle is that after the overload current passes through the thermal element, the bimetal is heated and bent to push the action mechanism to drive the contact action, thereby disconnecting the motor control circuit.
button
button switch national standard symbol for SB said. The operation mode is divided into inching and self-locking, the feedback mode is divided into with and without lights, and the normally open NO and normally closed NC can be used in any combination of
PLC
PLC: programmable controller in Chinese, which is the center of industrial control circuit.
switching power supply
switching power supply is a high-precision regulated power supply controlled by electronic technology. The main technical parameters are power supply devices with output voltage levels such as DC 24V and DC48V.
Servo motor and drive
Servo motor is a device that can control the speed and position of the motor with high precision. Servo mainly depends on the pulse to position. 1 pulse received by the servo motor. It will rotate the angle corresponding to 1 pulse to achieve displacement, and at the same time feedback a pulse to the encoder to form a semi-closed loop control system.
