Abstract
The utility model relates to a direct current explosion proof type power supply contactor comprising an electromagnetic part, which comprises a fixed iron core, a winding and a magnetic yoke, a static contact, a moving contact and a moving iron core. The static contact of the utility model is matched with the moving contact correspondingly, and the fixed iron core is fixedly connected with a base plate as a body; the winding and the magnetic yoke of the electromagnetic part are packaged inside a casing of the electromagnetic part, and the static contact is packaged inside an insulation base, which is covered with a cover; a plurality of sealing washers are arranged in both the clearance between the cover and the insulation base and the clearance between the insulation base and the casing of the electromagnetic part. Two pairs of arc ignition electrodes are connected between the moving contact and the static contact. The utility model has the advantages of large capacity, burning resistance of contacts, steady performance and excellent explosion proof performance; the utility model is mainly used as power supply master switches, charging switches or low-voltage and high-current direct current control components for industrial and mining enterprises, urban traffic, electric vehicles and communication equipments. And the utility model can be used in anti-corrosion and explosion proof working environment such as chemical enterprises, mines and other members.
Description
Technical field
The utility model relates to a kind of electric elements, particularly a kind of power contactor.
Background technology
The easy scaling loss of the most contact of used in the past this series products, coil easily generates heat, and performance is stable inadequately.As used for a long time DK232 type battery main switch, it comprises electromagnet portion, fixed contact and the moving contact of being made up of iron core, winding, yoke, moving iron core, the corresponding cooperation of its fixed contact with moving contact, electromagnet portion does not have fixed terminal, electromagnet portion, fixed contact and moving contact sealing are bad, and magnetic system has air gap when closed, meet vibrations and easily discharge, poor stability, the easy scaling loss of contact; Coil and yoke do not have sealing, and stale air is arranged on every side, cause drawbacks such as the easy heating of coil.Along with development of technology, it is big to be badly in need of a kind of capacity at present, stable performance, and the product that fail safe is good adapts to market demand.
Technology contents
The purpose of this utility model provides a kind of direct current explosion-proof type power contactor, solves the easy scaling loss of existing procucts contact, and coil easily generates heat, the technical problem that performance is stable inadequately.
The technical scheme of the utility model direct current explosion-proof type power contactor: it comprises electromagnet portion, fixed contact, the moving contact of being made up of fixed core, winding, yoke and moving unshakable in one's determination, the corresponding cooperation of its fixed contact with moving contact, it is characterized in that: fixed core and base plate are connected to one, the winding of electromagnet portion and yoke are encapsulated in the electromagnet portion shell, fixed contact partly is encapsulated in the insulating base, be covered with case above the insulating base, all be equipped with seal washer in the gap in the gap between case and the insulating base, between insulating base and the electromagnet portion shell.
Be connected with two pairs of arc electrodes between described moving contact and the fixed contact.
Beneficial effect: the utility model adopts totally enclosed type, has explosion prevention function, structurally compares with like product in the past, has following characteristics:
1, adopt helix tube type to have the electromagnet portion of fixed terminal (fixed core) to replace helix tube type not have the electromagnet portion of fixed terminal, electromagnet portion is closed fully, even voltage has certain fluctuation, magnetic circuit can not disconnect, and also has the characteristics that capacity is big, contact is difficult for scaling loss, good seal, stable performance.
2, case adopts high-intensity SMC unsaturated polyester glass fiber sheet molding compound compacting to form, and explosion-proof performance is good.Insulating base adopts well behaved encapsulated plastic DMC, and the electromagnet portion shell is packaged as a whole winding and yoke, and the coil thermal diffusivity is good, also makes the outward appearance of product and overall performance better.
3, contact system has been installed two pairs of arc electrodes, helps protecting contact.
The utility model is mainly used in industrial and mining enterprises, on urban transportation, motor vehicle, the communication apparatus, as the DC control element of battery main switch, charge switch or low-voltage, high electric current.Be mainly used in industrial and mining enterprises, on urban transportation, motor vehicle, the communication apparatus, as the DC control element of battery main switch, charge switch or low-voltage, high electric current.Can be used in anticorrosion, the explosion-proof operational environment such as chemical industry, mine.
