Specification
Electromagnetic contactor (contactor) refers to an electrical appliance that
uses the current flowing through the coil to generate a magnetic field in
industrial electricity to close the contact so as to control the load. The
contactor is composed of electromagnetic system (armature, stator core,
electromagnetic coil), contact system (normally open contact and normally
closed contact) and arc extinguishing device.
Structural composition
Electromagnetic contactor is mainly composed of transmission device
(electromagnetic mechanism), contact device (actuator) and arc extinguishing
device.
1. Electromagnetic mechanism
The electromagnetic mechanism includes three parts: moving core (armature),
static core and electromagnetic coil. The electromagnetic coil is connected
with current to generate electromagnetic suction and drive the contact to act.
Electromagnetic mechanism is one of the important parts of electromagnetic
contactor. The electromagnetic mechanism is composed of coil, iron core (static
iron core), armature (moving iron core), pole shoe, iron yoke and air gap. The
coil and iron core in the electromagnetic mechanism do not move in the working
state; The armature is movable.
The electromagnetic mechanism converts the electromagnetic energy generated by
the electromagnetic coil into mechanical energy through the action state and
action process of the armature and the corresponding mechanical mechanism to
drive the contact to close or open, so as to realize the control purpose of the
controlled circuit.
2. Contact device
There are many structural forms of contact, which can be divided into: main
contact and auxiliary contact according to the control circuit;
The contact is divided into normally open contact and normally closed contact
according to its original state;
The contact is divided into bridge contact and finger contact according to its
structural form.
3. Arc extinguishing device
Arc extinguishing cover is an insulated and high temperature resistant arc
extinguishing device made of clay and asbestos cement. It is a simple arc
extinguishing device.
When using the arc extinguishing cover device to extinguish the arc, the
longitudinal seam arc extinguishing method is generally used in the arc
extinguishing cover.
Common arc extinguishing devices: arc extinguishing cover (arc resistant clay,
asbestos cement and arc resistant plastic), arc extinguishing grid (arc
resistant grid sheet copper plated thin steel sheet), magnetic blowing arc
extinguishing device (an arc extinguishing coil is connected in series in the
contact circuit).
4. Other components, including reaction spring, buffer spring, transmission
mechanism and shell, etc.
- Q: What is the role of the contactor
- Can be frequently connected with the high current control (up to 800A) circuit device, so often used in the motor as a control object, can also be used to control the plant
- Q: Research on Relay Parameter Detection Technology Based on Single Chip
- Similarly, the release time of the relay can be obtained. At the same time the test device can also monitor the contact resistance of the contacts.
- Q: Seeking Star Triangle to start the contactor on and off the order and process
- Start, in order to reduce the starting current it! It is certainly the star of the contactor first action it! The Then disconnect the star of the contactor, and then connected to the triangle contactor.
- Q: Use Star Triangle to start contactor's order and process method
- Coil power, the motor to do triangular connection, and in the pressure operation, to achieve the star - triangular automatic switching buck starting. KM
- Q: Briefly describe the type of contactor
- One, permanent magnet actuator to save a lot of energy to maintain the coil power consumption, environmental protection and energy conservation.
- Q: Three-phase AC contactor has several terminals that have a role
- The power is applied and the contact point is disconnected after power failure
- Q: The difference between electromagnetic contactor and AC contactor
- C contactor is also a kind of electromagnetic contactor, because the AC contactor is the use of alternating current to let the coil produce magnetic field (magnetic flux), so that contactor to pull.
- Q: What does the contactor lock mean?
- t is through the start button (jog) after the start of the contactor coil to continue to have electricity, resulting in maintaining the contact path state
- Q: Contactor frequent pull is how the matter
- the coil terminal bad contact, need to tighten the terminal screws to make good contact.
- Q: How does the contactor works
- When the coil is powered off, the electromagnetic suction disappears, the armature in the release of the role of the release of the spring
