The Forklift Contactor Has The Advantage Of High Breaking Capacity
- Oct 17, 2017 -

Forklift contactor is mainly used for power to excellent electric forklift and Toyota electric forklift.

Forklift contactor is divided into: main power contactor, walking contactor, bypass contactor, re-contactor, hydraulic lifting contactor, steering contact, etc., Forklift Contactor suitable for use in electric forklifts, battery forklifts, golf carts , Beach trams and other electric cars to use.

The role of the forklift contactor is mainly able to close, carry and disconnect the normal current and the provisions of the overload current disconnect and close the device device. Contactor is a highly versatile electromagnetic type, it can frequently turn on and off the AC, DC main circuit, and can achieve long-distance control, mainly used to control the electric forklift power supply. AC contactor main contact is usually 3 pairs (three-phase power), mainly used in the electric forklift charger on the majority. Forklift Contactor The main contact of the DC contactor is 2 pairs. Contactor of the dynamic and static contact is generally placed in the arc cover, there is a vacuum contactor is the dynamic contact in the vacuum bubble, it has a high breaking capacity, long life, Forklift Contactor high operating frequency, small size and weight Light and other advantages.

Forklift contactor is mainly divided into: the main power contactor, walking contactor, a good contactor contact is mainly used high wear resistance, anti-oxidation material system; base treasure forklift long-term supply of various electric / battery forklift contact Hand, a large; forklift contactor models are: DC182B-7/8, D; SW82, ZJ400D / DE, ZJ50A, ED2; B3DC12 / B3DC1136V import and domestic series.

Forklift contactor is divided into: main power contactor, walking contactor, bypass contactor, re-contactor, hydraulic lifting contactor, steering contact, etc., suitable for use in electric forklifts, battery forklifts, golf carts , Beach trams and other electric cars to use. Forklift Contactor The role of the forklift contactor is mainly able to close, carry and disconnect the normal current and the provisions of the overload current disconnect and close the device device. Contactor is a highly versatile electromagnetic type, it can frequently turn on and off the AC, DC main circuit, and can achieve long-distance control, mainly used to control the electric forklift power supply. AC contactor main contact is usually 3 pairs (three-phase power), mainly used in the electric forklift charger on the majority. The main contact of the DC contactor is 2 pairs. Contactor of the dynamic and static contact is generally placed in the arc cover, there is a vacuum contactor is the dynamic contact in the vacuum bubble, it has a high breaking capacity, long life, high operating frequency, small size and weight Light and other advantages. Forklift contactor works is: when the contactor coil power, the coil current will produce a magnetic field, Forklift Contactor the magnetic field generated by the static core to produce electromagnetic suction suction core, and drive the DC / AC contact point action, normally closed contact off , Normally open contact closed, the two are linked. When the coil is powered off, the electromagnetic suction disappears, the armature in the release of the role of the release of the spring, Forklift Contactor so that contact recovery, normally open contact open, normally closed contact closed.

The rated voltage of the forklift contactor is mainly 12V, 24V, 36V, 48V, 60V, 72V and 80V, the rated current is mainly in the 100A-600A or so, the contact life is mainly in the 100,000 -50 million times, contactor Coil life is mainly about 100,000 times. Select the contactor from its working conditions to choose, mainly need to consider the following factors:

 A, control the AC load should use AC contactor, control the DC load is selected DC contactor.

 B, the use of forklift contactor category should be consistent with the nature of the load.

C, the rated operating voltage of the main contact should be greater than or equal to the voltage of the load circuit.

 D, the main contact of the rated operating current should be greater than or equal to the load circuit current, Forklift Contactor but also note that the contactor contact contact current is rated under the conditions (rated operating voltage, use category, operating frequency, etc.) The normal working current value, when the actual conditions of use are different, the current value also changes with the change.

 E, the rated voltage of the suction coil should be consistent with the control circuit voltage, the contactor in the coil rated voltage 85% and above should be able to reliably pull.
