Description
Technical field
The utility model relates to the Design and manufacture field of high-voltage switch equipment, particularly relates to a kind of pole parts of pole.
Background technology
Existing pole, generally by vacuum interrupter, upper outlet terminal, lower wire end, be flexible coupling, pull bar and epoxy resin housing form.Upper outlet terminal described at present adopts the quiet end conductor of screw and vacuum interrupter to be fixedly connected with usually, lower wire end is fixed on mould, entirety passes through vacuum pouring or pressure gel (APG) technological forming by insulating material such as epoxy resin again, but the general entirety of the pole that this kind produces is larger, material is many, and (be generally air due to electric conductor and insulating material and insulating gas, nitrogen or sulphur hexafluoride) three medium intersection point field intensity larger, pole inner chamber puts problem because the existence of the metal tip and three intersection points such as to be flexible coupling also easily produces the local field strength office of causing bigger than normal.
Application number CN 201380007680.3 discloses a kind ofly has the embedded of vacuum interrupter or assembly type pole parts and manufacture method thereof, described embedded pole part has vacuum interrupter, upper terminal, lower terminal, wherein upper terminal surface coverage has damping layer, the pole moved end of vacuum interrupter to link together with lower wire end and insulated tension pole by being flexible coupling, upper terminal is poured into an integrated entity by insulating material owing to being coated with damping layer again, be unfavorable for the heat radiation of conductor and three medium intersection point field intensity between conductor and insulating material and extraneous gas are higher, simultaneously higher in three medium intersection field intensity of arc control device lower end and epoxy and air, arc control device also easily produce the concentrated problem of field intensity with the end of the junction be flexible coupling and lower wire end, cause the Electric Field Distribution of pole uneven for above-mentioned reasons, be unfavorable for that Total Product miniaturization affects the insulation property of pole entirety simultaneously.
Application number CN 201220468759.9 discloses a kind of pole, the upper outlet rod including outlet terminal and be connected with described upper outlet terminal, owing to being outside equipped with the field intensity problem of non-uniform that cover body solves junction in joint portion, upper end, but still can not get improving in the field intensity concentration problem of upper and lower side conductor and epoxy resin and internal gas three medium intersection, and lower end can not be solved to be flexible coupling the electric field concentration problem that tip causes, simultaneously because by insulating material is coated, therefore conductor is unfavorable for that product dispels the heat.
Utility model content
The utility model solves above-mentioned technical problem, provides a kind of pole parts of pole.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of pole parts of pole, comprise shielding, lower shielding and vacuum extinction chamber component, described upper shielding and lower shielding are embedded by casting insulated material and are fixed in the housing of pole, described vacuum interrupter member parallel or perpendicular to being axially fixed in the housing of pole of shielding up and down.
Further, described upper shielding and lower shielding adopt the axial structure that intersects vertically of two annular solids, and intersection adopts fillet excessive, and the end of annular solid adopts fillet excessive, and described annular solid surface array arranges multiple through hole.
Further, described annular solid adopts the polyamide of metallic plate, wire netting, the polyamide including electric conducting material or surface spraying electric conducting material.
Further, described upper shielding and the upper end high-pressure conductor of pole are by being mechanically connected or pouring into a mould one, and described lower shielding and the lower end high-pressure conductor of pole are by being mechanically connected or pouring into a mould one.
Further, described insulating material adopts epoxy resin, polyamide, polyethylene or other synthetic resin.
Adopt the technical solution of the utility model, by the upper and lower side shielding arranging pole parts, high electric field is transferred to insulating barrier inside, thus the problem of the Electric Field Distribution inequality of shielding pole upper and lower sides, the mainly tip of three medium intersections and the electric conductor problem that causes electric field value to exceed standard.Optimize the Electric Field Distribution of pole entirety, making full use of the higher tolerance field intensity of solid insulating material makes whole insulation system more simply avoid bubble-discharge, avoid electric conductor etc. to be directly all coated on insulating material inside causes heat radiation poor simultaneously, because temperature raises the reliability reducing product, production cost also can be lower simultaneously.After adopting shielding, can also improve withstand voltage level over the ground, thus can reduce creep distance, whole equipment size is reduced, and equipment is more compact, and has higher reliability.Solve the miniaturized aspect of existing product insulation weak link aspect and solid insulation equipment, have extremely important effect, economic benefit is objective.Insulating material is selected thermoplastic to be conducive to improving production rate to reduce impact on environment simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation that the utility model vacuum interrupter member parallel is installed;
Fig. 2 is the structural representation filled after the utility model vacuum extinction chamber component;
