Abstract
The utility model discloses a phase column of a vacuum contactor, which comprises a vacuum arc extinguish chamber, a contact arm, an outlet line base, a pull rod and an insulating base, wherein the vacuum arc extinguish chamber is provided with a static end and a movable end; the contact arm is fixedly connected with the static end through a bolt, and electrically connected with the static end; the outlet line base is electrically connected with the movable end; the pull rod is connected with the movable end, and controls the movable end to control whether the static end and the movable end conduct electricity; and the insulating base is directly formed by solidly sealing and casting epoxy resin outside the vacuum arc extinguish chamber, the contact arm and the outlet line base. Because the insulating base is directly formed by solidly sealing and casting epoxy resin outside the vacuum arc extinguish chamber, the contact arm and the outlet line base, the vacuum arc extinguish chamber is externally insulated and not affected by the external environment. The volume of the phase column can be minimized, and the vacuum contactor also can be minimized, so that the phase column is energy-saving and environment-friendly.
Description
Technical field
The utility model relates to a kind of vacuum contactor phase post.
Background technology
The phase post is the parts of vacuum contactor most critical, and it comprises: a vacuum interrupter, a contact arm, a pull bar and an insulating cover.This vacuum interrupter, it has a quiet end and a moved end; This contact arm, it connects quiet end by bolted, and is connected with quiet end formation conduction; This pull bar connects the moved end, and whether conduct electricity to control quiet end and moved end the control moved end; This insulating cover is processing earlier, is socketed in then outside this vacuum interrupter and the contact arm.The galvanic circle of phase post, end conduction connects contact arm, and other end conduction connects the moved end.This phase post has following shortcoming: 1, the external insulation of vacuum interrupter is to expose in air, is subject to such environmental effects, for example dust, water vapour, salt fog etc.; 2, the circuit of the galvanic circle of phase post conduction connection moved end is long, and resistance is big, non-uniform electric.
The utility model content
The utility model provides a kind of vacuum contactor phase post, and it has overcome the existing long deficiency of circuit that is subject to such environmental effects, conduction connection moved end of background technology phase post.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of vacuum contactor phase post, it comprises: a vacuum interrupter, a contact arm, an outlet seat, a pull bar and an insulating base.This vacuum interrupter, it has a quiet end and a moved end; This contact arm, it is fixedly connected on quiet end, and is connected with quiet end formation conduction; This outlet seat, its conduction connects the moved end; This pull bar connects the moved end, and whether conduct electricity to control quiet end and moved end its control moved end; This insulating base, it is cast in by epoxy resin, and solid envelope directly forms outside this vacuum interrupter, contact arm and the outlet seat.
In the preferred embodiment of the present utility model, this outlet seat has an inner and outer end, and this inner is positioned at insulating base and conduction connects the moved end, and this outer end is exposed to outside the insulating base.
In the preferred embodiment of the present utility model, this contact arm has an inner and outer end, and this inner is fixedly connected, conduction connects quiet end, and stretch out outside the insulating base outer end.
In the preferred embodiment of the present utility model, this outlet seat the inner is flexible coupling to conduct electricity by one and connects the moved end.
In the preferred embodiment of the present utility model, this is flexible coupling is a sheet metal, and its end connects outlet seat the inner by screw connection, conduction, and the other end connects the moved end.
In the preferred embodiment of the present utility model, this outlet seat is side " Z " shape, and its two ends is respectively the inner and outer end.
In the preferred embodiment of the present utility model, also comprise: an inserts, it is located on the insulating base.
The technical program is compared with background technology: solid envelope directly forms outside this vacuum interrupter, contact arm and the outlet seat because insulating base is cast in by epoxy resin, therefore the vacuum extinction outdoor insulation is not affected by the external environment, the volume of phase post can be as far as possible little, it is very little that vacuum contactor also can be done, not only energy-conservation but also environmental protection.Because contact arm the inner is fixedly connected, conduction connects quiet end, and is therefore easy to connect, can reduce machining accuracy, reduces the cost.Owing to be provided with the outlet seat, therefore can shorten phase post galvanic circle conduction and connect distance, resistance is little, and connection is simple, reliable, and Electric Field Distribution is good.Because the inner of this outlet seat is positioned at insulating base, the outer end is exposed to outside the insulating base and connects external circuitry with conduction, so outlet seat fixing-stable.Connect the moved end because this outlet seat the inner is flexible coupling to conduct electricity by one, therefore can avoid influencing the conduction connection because of the moved end activity.Because this sheet metal one end connects outlet seat the inner by screw connection, conduction, therefore can guarantee the conduction switching performance, strain.Because this outlet seat is side " Z " shape, can shortens conduction and connect distance, fixing-stable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 has illustrated the generalized section of the vacuum contactor phase post of a preferred embodiment.
Fig. 2 has illustrated the left side of the vacuum contactor phase post of a preferred embodiment and has looked schematic diagram.
