Description
Technical field
The present invention relates to a kind of fuse switch, particularly relate to a kind of outdoor ac high voltage drop fuse that have employed anticorrosion pouring technique and build steel pin and use integrated flow deflector.
Background technology
The outdoor drop-out fuse of current use is used for overhead distribution system, provides the visible instruction of overcurrent protection, fault-current protection and fuse member action.Because it has visible fracture intuitively, and when using together with load cut-off, the effect playing on-load switch can cut-off load current, creates safe operational environment to maintenance circuit and plant maintenance, is used widely.
But in electric line, the high voltage drop-out type fuse cutout generally used at present, due to the feature cause of the current lower carriage casting model used in the industry, cause the flow deflector that contacts with wire installed in the above directly can not touch fusion tube component, and need to carry out indirect contact water conservancy diversion by installing other one piece of flow deflector, this Installation Modes is common practice in the industry, but this also exists some problems, the connection of two pieces of flow deflectors can not be accomplished intimately seamless, the oxidation on flow deflector surface or the gap existing between them not only increase resistance, and reduce conductance, easily break down.In addition, the steel pin casting craft of existing fuse is all directly build, then build material-cement and there is certain corrosivity, just can corrode steel pin again in direct casting process like this, the rigidity of steel pin, intensity are caused damage, fuse is also increased in use to the probability occurring damaging fault.Therefore, being badly in need of one on the market neither needs to change fuse production technology, production equipment on a large scale, does not increase production cost, the damage failure rate of fuse can be dropped to minimum outdoor ac high voltage drop fuse again.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide the integrated flow deflector that a kind of use can be installed at lower carriage after carrying out ingenious Curve guide impeller, and the outdoor ac high voltage drop fuse that antiseptic performance is more reliable, damage failure rate is low, long service life is carried out to steel pin.
To achieve these goals, present invention employs following technical scheme: a kind of outdoor ac high voltage drop fuse, comprise porcelain insulator, middle installation steel pin, fusion tube component, be arranged on the upper backup pad on installation steel pin, de-icer boot, static contact and hook, and the flow deflector be arranged on lower installation steel pin and lower carriage, described flow deflector is integrated guide flow, flow deflector is provided with installing hole I, installing hole II, inclined-plane and rivet hole, flow deflector is fixedly mounted on lower carriage by installing hole I and rivet hole, by installing hole II crimping lead wire together with lower tension disc.
The present invention further can: described flow deflector is connected with L-type shell fragment by rivet.
Described flow deflector and the contact-making surface of fusion tube component are provided with bar shaped projection.
Described flow deflector is copper material flow deflector, and its electroplate.
The gradient on the inclined-plane of described flow deflector to be suitable for being arranged on lower carriage for benchmark with flow deflector, makes flow deflector be the flow of continuity integrated guide.
The one end of installing steel pin, upper installation steel pin and lower installation steel pin in the middle of described is fixedly mounted in porcelain insulator by building material, and middle steel pin, upper installation steel pin and lower installation steel pin are installed and build between material be provided with anti-corrosion protective film.
Described material of building is microdilatancy quick hardening cement.The cement that the present invention the uses microdilatancy quick hardening cement that is a kind of import, it possesses uvioresistant, quick-drying (time of building is short), the feature such as firm of condensing.
Described anti-corrosion protective film be by install in centre steel pin, on steel pin and lower installation steel pin be installed coat the asphalt film that pitch formed.Asphalt film forms the medium of expansion buffer between steel pin and cement installing, make steel pin to be firmly cast in porcelain vase.
In the present invention fusion tube component comprise fusion tube, be arranged on the fusion tube pressed on ring at fusion tube two ends, fusion tube under ring, fuse, lower turnover panel and pressure releasing cap etc.; Pressure releasing cap is arranged on the upper end of fusion tube, and presses tactile connection with the groove of static contact; Under fusion tube, ring is connected with lower carriage, flow deflector by lower moving contact seat.
Be provided with a spring between above-mentioned static contact and de-icer boot, static contact and pressure releasing cap can be formed and effectively press tactile connection.
Above-mentioned upper backup pad is respectively equipped with left tension disc and right tension disc, for crimping lead wire.
Based on earlier application or the patented technology of applying on the same day of applicant, outdoor ac high voltage drop fuse can also increase some designs, as being provided with convex surface contact in the hemispherical groove of the static contact contacted with the pressure releasing cap of fusion tube upper end, the quantity of convex surface contact is more than three; Be provided with an accelerator in the side at hook, one end of accelerator contacts etc. with the fusion tube pressed on ring of fusion tube component.
Advantage of the present invention:
1., by the Curve guide impeller to flow deflector, be applicable to be arranged on existing lower carriage, make to adopt integrated flow deflector scheme to be achieved, which enhance conductance, the fault that before avoiding, product causes due to loose contact.
2. asphalt film is installing the medium forming expansion buffer between steel pin and cement, steel pin is made firmly to be cast in porcelain vase, and asphalt film makes steel pin directly not contact with cement, prevent steel pin from being corroded by cement, namely carried out to steel pin the useful life that antiseptic performance is more reliable, damage failure rate is low, extend fuse.
