Product Description
The main functions and functions of the machine contactor are as follows:
Achieve remote control: in the work environment, the operator needs to stay away from the dangerous area, and the contactor can remotely control the start and stop of the motor, transformer and other equipment by pressing a button or switch. This remote control capability not only ensures the safety of the operator, but also improves work efficiency.
Frequent operational control: Equipment needs to be started and stopped frequently in the production process. The contactor can respond quickly and complete multiple opening and closing actions in a short time to meet the needs of frequent control in industrial production. This high frequency operation capability reduces wear and extends service life of the equipment.
With protection function: When the circuit is overloaded or short-circuited, the contactor can achieve interlock protection through its auxiliary contacts to prevent circuit damage. At the same time, the arc extinguishing device equipped with the contactor can effectively reduce the generation of arc, protect the contact from damage, and ensure the safe and stable operation of the equipment.
Switching function: A contactor is an electrical component used to control an electrical circuit. It is a device that connects or disconnects current through mechanical contact, and is commonly used in electrical control systems.
To sum up, machine contactors play a vital role in industrial control and power systems, and their presence greatly improves production efficiency and safety.
Washing Machine Accessories Contactor refers to the contactor in Washing Machine accessories, which is an important part of the electrical system of Washing Machine. It is usually installed near the control board or motor of the Washing Machine.
Here's a closer look at it:
Effect of action
Control circuit on and off: the main function of the contactor is to control the start, stop and forward and reverse of the washing machine motor. By controlling the contact closure and disconnection of the contactor, the power supply and power off of the motor can be realized
Protection of circuit safety: When the Washing Machine is overloaded, short circuit and other faults, the contacter will automatically cut off the circuit to protect the motor and other electrical components from damage.
Realize automatic control: the contactor can cooperate with the control system of Washing Machine to realize automatic control. For example, by controlling the contact closure time and sequence of contactors, the water level control of Washing Machine, automatic drainage and other functions can be realized.
How it works
The contactor is mainly composed of electromagnetic mechanism, contact system and arc extinguisher. The electromagnetic mechanism is composed of coil, iron core and armature. When the coil is electrified, the iron core generates a magnetic field, which attracts the armature to move and makes the contact system closed. When the coil is powered off, the magnetic field disappears, the armature returns to its position under the action of the spring, and the contact system is disconnected.
The contact system is divided into main contact and auxiliary contact. The main contact is used to control the main circuit of the motor, and the auxiliary contact is used to control the control circuit. The arc extinguishment device is used to extinguishment the arc generated when the contact is disconnected and protect the contact from damage.
