Description
Technical field
The utility model belongs to high pressure power transmission and distribution switching technique field, relates to a kind of packaged type radome being arranged on dynamic/static contact.
Background technology
Gas-insulated switchgear is good with its security performance, and reliability high has obtained general application at present in high-voltage fence. In product design process, conventionally can improve by increasing the mode of dielectric the blowing pressure or increase insulation distance and increase radome the dielectric strength of product. But the product of low pressure dielectric is more and more subject to user's favor, solve Insulation Problems so can only increase the method for insulation distance, it can make product size increase, and not only product direct cost increases, nor meets the requirement of user to miniaturization.
Adopt shielding case structure can improve near the Electric Field Distribution of high pressure fracture, thereby be conducive to the miniaturization of insulation system, meet the requirement of user to product miniaturization. But in prior art, particularly, in straight ejector half gas-insulated charger, dynamic/static contact is will mutually peg graft coordinate contact or separate, thereby the inconvenient radome of installing on static contact, can only increase insulating properties by other method, the structure that can not further dwindle product, has increased cost; Or radome has been installed on static contact, but structural design is unreasonable, shield effectiveness is poor, and then cause insulation effect poor.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of structure of dwindling product that is beneficial to is provided, and reduces costs; And can improve near Electric Field Distribution dynamic/static contact, the packaged type radome of good insulating.
Packaged type static contact radome of the present utility model, comprises the moving contact and the static contact that are arranged in housing, and described moving contact is connected to push rod, is pushed away forward or pulls back contact and then made moving contact contact with static contact or disconnect by described push rod; Described static contact is cylinder-like structure, and a sliding sleeve is installed on the outer surface of described static contact back segment, and a static contact radome is installed on described sliding sleeve; The outer surface in described static contact stage casing offers the one section of chute extending along static contact length direction; In the inner chamber of described static contact leading portion, be mounted with one section of active force spring backward; In the inner chamber of described static contact, the rear end of spring has a sliding part that can move forward and backward along static contact inwall, described sliding sleeve is connected on described sliding part by the connector through chute; Described moving contact periphery is coated with a fixing promotion cover, and the front end of described promotion cover has the opening that diameter is greater than static contact overall diameter and matches with static contact overall diameter; Plug in the process contacting at moving contact and static contact, described static contact radome can be pushed cover and promote forward; In the process separating with static contact at moving contact, described static contact radome can be under the effect of spring, along with sliding sleeve comes back to the back segment of static contact. The advantage of such structural design is: in dynamic/static contact contact, static contact radome can move forward automatically, does not hinder the contact of dynamic/static contact, after dynamic/static contact separates, can automatically get back to backward again the back segment of static contact. Arranging one can be along the mobile static contact radome in static contact surface, under the state that can separate at dynamic/static contact, play the insulating effect between dynamic/static contact, be beneficial to the distance of dwindling between dynamic/static contact, and then be beneficial to the size of dwindling product entirety, reduce and taken up room and production cost.
The rearmost end of described static contact is provided with a static contact arcing contact being made by the material of ablation resistance, and the center of described static contact arcing contact has through hole; The center of described moving contact be provided with one that be made by the material of ablation resistance, can plug the moving contact arcing contact coordinating with the through hole of static contact arcing contact; The front end of described moving contact arcing contact extends and is exposed at outside moving contact towards static contact direction, within promoting cover. The benefit of such structural design is: before dynamic/static contact contact, the arcing contact of dynamic/static contact first contacts, when dynamic/static contact separates, after the arcing contact of dynamic/static contact, separate, thereby dynamic/static contact is in contact and separating, can not produce electric arc, electric arc is born by the arcing contact of ablation resistance, and this has extended the service life of dynamic/static contact.
Between the outer surface of described static contact radome and static contact arcing contact rear end, form an annular slot, the front end of described promotion cover has the flange that can insert in described slot, in the process of dynamic/static contact contact, the flange of described promotion cover inserts in described slot, and such structural design benefit is: while promoting cover promotion static contact radome, stability and reliability are all fine.
