Description

Dry node contactor capable of freely combining alarm modes

Technical Field

The utility model relates to the technical field of contactors, in particular to a dry node contactor capable of freely combining alarm modes.

Background

The Contactor (Contactor) is an electric appliance which utilizes the current flowing through a coil to generate a magnetic field in industrial electricity to close a contact so as to control a load, and comprises an electromagnetic system, a contact system and an arc extinguishing device. The contactor can be used for controlling power loads of factory equipment, electric heaters, working machines, various power units and the like, and not only can be used for switching on and switching off a circuit, but also has a low-voltage release protection effect. The principle is that after the electromagnetic coil of the contactor is electrified, a strong magnetic field can be generated, so that the static iron core generates electromagnetic attraction to attract the armature and drive the contact to act: the normally closed contact is disconnected; the normally open contact is closed, and the normally open contact are linked. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released under the action of the release spring to restore the contact: closing the normally closed contact; the normally open contact is open. In electrical engineering, a contactor is often used as a control object for a motor because of a device capable of quickly switching off main circuits of alternating current and direct current and frequently switching on a circuit of a large current control (some types can reach 800 amperes), and can also be used for controlling electric loads such as factory equipment, electric heaters, working machines and various electric power units, and the contactor not only can switch on and off the circuit, but also has a low-voltage release protection effect. The contactor has large control capacity and is suitable for frequent operation and remote control. The contactor is one of important elements in an automatic control system, the conventional contactor cannot firmly fix an electric wire during wiring, so that the electric wire is easy to loosen to cause faults such as open circuit and the like, and the contactor can generate certain heat during use.
