Abstract
The utility model discloses a kind of D.C. contactor arc insulating apparatus, include the shell body of at least one end open, the opening of the shell is provided with end cap, arc-chutes are formed with cavity between the shell body and end cap, a pair of stationary contacts and movable contact are provided with the arc-chutes, and the arc-control device for arc extinguishing, the arc extinguishing chamber interior walls are provided with ceramic layer formation arc insulating apparatus.The D.C. contactor arc insulating apparatus is coated in arc extinguishing chamber interior walls formation arc insulating apparatus using ceramic material, because ceramic material heat-resisting ability is much larger than plastic material, and ceramics will not decompose dusty gas at high temperature, therefore the arc insulating apparatus can be prevented effectively from plastic material arc insulating apparatus decomposite at high temperature pollution cavity environment gas, so as to ensure that the cleanliness factor of cavity environment, the electrical performance indexes of product are improved.
Description
Technical field
The utility model is related to a kind of D.C. contactor, more particularly to a kind of D.C. contactor arc insulating apparatus.
Background technology
Existing D.C. contactor, its arc insulating apparatus uses the arc insulating apparatus of plastic material, this plastic material
Arc insulating apparatus can decomposite dusty gas at high temperature, so that the pollution of contactor internal cavity environment is caused, reduction product
Electrical performance indexes.
The content of the invention
In order to overcome drawbacks described above, the utility model provides a kind of D.C. contactor arc insulating apparatus, prevents cavity environment
It is contaminated, improve product electrical performance indexes.
The utility model is to solve the technical scheme that its technical problem is used：A kind of D.C. contactor arc dress
Put, including at least shell body of one end open, the opening of the shell is provided with end cap, in the cavity between the shell body and end cap
Arc-chutes are formed with, a pair of stationary contacts and movable contact, and the arc-control device for arc extinguishing, the arc extinguishing are provided with the arc-chutes
Chamber interior walls are provided with ceramic layer formation arc insulating apparatus.
As further improvement of the utility model, the arc-chutes are made up of housing, upper supporting piece and lower support element, should
Upper supporting piece and lower support element be respectively arranged on the upper and lower port of the housing so as to forming arc-chutes, and stationary contact described in a pair connects
Terminal is on the upper supporting piece, and the dynamic contact point is formed for movable contact spring, and the moving contacting plate is fixed on transmission core bar, should
It is driven core bar activity and passes through the lower support element.
As further improvement of the utility model, the ceramic layer is formed in the junction of the housing and lower support element
On breach, the lower support element to should breach be provided with fin.
As further improvement of the utility model, the top and bottom of the shell body are respectively equipped with opening, and two
End cap is respectively equipped with opening.
The beneficial effects of the utility model are：The D.C. contactor arc insulating apparatus is coated in arc-chutes using ceramic material
Wall formation arc insulating apparatus, because ceramic material heat-resisting ability is much larger than plastic material, and ceramics will not have been decomposed at high temperature
Dusty gas, thus the arc insulating apparatus can be prevented effectively from plastic material arc insulating apparatus decomposite at high temperature pollution cavity ring
The gas in border, so as to ensure that the cleanliness factor of cavity environment, improves the electrical performance indexes of product.

There is the gas of pollution, so as to protect the cleanliness factor of arc extinguishing room air, it is to avoid pyrolytic produces dusty gas, improve
The electrical property of product.
Wherein, the arc-chutes are made up of housing 4, upper supporting piece 5 and lower support element 6, the upper supporting piece and lower support element
It is respectively equipped with the upper and lower port of the housing to form arc-chutes, the binding post of contact point described in a pair is located at the upper support
On part, the dynamic contact point is that moving contacting plate 7 is formed, and the moving contacting plate is fixed on transmission core bar 8, transmission core bar activity
Through the lower support element.The ceramic layer forms breach 31, the lower support in the junction of the housing and lower support element
On part to should breach be provided with fin 61.Ceramic layer and fin coordinate, and improve the stability of arc insulating apparatus.The shell body it is upper
End and lower end are respectively equipped with opening, and two openings and are respectively equipped with end cap.
The D.C. contactor arc insulating apparatus is coated in arc extinguishing chamber interior walls formation arc insulating apparatus using ceramic material, due to ceramics
Material heat-resisting ability is much larger than plastic material, and ceramics will not decompose dusty gas, therefore the arc insulating apparatus at high temperature
The arc insulating apparatus that plastic material can be prevented effectively from decomposites the gas of pollution cavity environment at high temperature, so as to ensure that cavity
The cleanliness factor of environment, improves the electrical performance indexes of product.
