Described arc keeper and lever transmission mechanism adopt BMC moulding compound compacting integrated design.
The arc keeper of described arc keeper available metal material directly is pressed into lever transmission mechanism as inserts and moulding compound.
Described modular arc control device adopt the compacting of BMC moulding compound, are a utmost point one Room, can multipolely be combined into multipole contactor.
Described pedestal is pressed into by the BMC moulding compound, about two, middle angle bar connects.
Described double loop flexible connection is the double loop.
Be provided with mounting seat in the modular arc control device of described modular vacuum contactor, vacuum interrupter, last joint cover, following joint cover, the double loop flexible connection is assembled on the base, this modular vacuum contactor, abandoned the tower structure of original complexity, adopted simple BMC moulding compound pressing structure, assembling is quick, debugging is convenient, and cost is low.
Upper cover plate made by described transparent material and irony lower cover each several part is assembled on the left and right sides pedestal of BMC moulding compound compacting, therefore realize totally-enclosedly, avoided the exposed of parts, make product avoid damaging, effectively avoid extraneous dust, foreign material etc. to fall into internal body, guaranteed the reliability of work.
Described employing modular design is avoided complicated general frame, especially when arranging a plurality of vacuum tubes, only needs irony angle bar lengthening is installed on the pedestal of the left and right sides, becomes multi-polar structure.
The upper cover plate sealing is described, arc control device segment lever transmission mechanism, last joint cover, following joint cover, double loop flexible connection etc.
The lower cover sealing is described, part electromagnetic system, auxiliary contact and reaction spring etc.

Embodiment:
Provide most preferred embodiment of the present invention according to Fig. 1 to Fig. 5 below, and described in detail, enable to understand better function of the present invention, characteristics.
Consult Fig. 2, for arc keeper (3) the available metal material on the lever transmission mechanism of the present invention (6) as inserts and moulding compound press forming, its arcwall face of lever transmission mechanism (6) contacts with the bearing-surface of adjustment screw (2) head.Because arcwall face and plane contact always line contact, thereby arc keeper (3) is that line contacts with the support bottom surface of adjustment screw (2) at this moment.In conjunction with shown in Figure 1, after assigning cut-offing instruction, electromagnetic attraction disappears, armature (13) is under the effect of reaction spring (15), drive leverage (6) and arc keeper (3) and do rotation counterclockwise, because arc keeper (3) remains line with adjustment screw (2) and contacts, even thereby lift in arc keeper (3) inclination, adjustment screw (2) still is a rectilinear motion up and down, the scaling loss of contact evenly, slightly like this, avoid localized burn serious, even cause melting welding, thereby improved properties of product.
Consult Fig. 1, modular vacuum tentaculum of the present invention mainly comprises armature (13), electromagnetic system (14), auxiliary contact (16), irony lower cover (17), left and right sides pedestal (4), double loop flexible connection (7), following joint cover (11), goes up joint cover (1), vacuum interrupter (9), lever transmission mechanism (6), adjustment screw (2), arc keeper (3), moving conductive rod (8) and reaction spring (15) etc.Lever transmission mechanism (6) is provided with through hole, supplies the double-screw bolt of adjustment screw (2) to penetrate.Moving conductive rod (8) is extended in the double-screw bolt lower end of adjustment screw (2), and an end of moving conductive rod (8) links to each other with adjustment screw (2).
As shown in Figure 1, and in conjunction with Fig. 2 to Fig. 5, vacuum interrupter (9), last joint cover (1), following joint cover (11) and double loop flexible connection (7) all are assembled in the module arc control device base (2) of BMC moulding compound compacting and go up (consulting Fig. 4), connect by middle angle bar (18A, B), assembling is quick, debugging is convenient, and cost also reduces greatly.The left and right sides pedestal (4) that entire product is pressed into by the BMC moulding compound is gone up carrying and is installed, and connects left and right sides pedestal (4) by the middle angle bar (18A, B) by the number of poles requirement, can be assembled into the structure of a utmost point, two utmost points, two utmost points, four utmost points, five utmost points and multipole number.Upper cover plate (10) adopts transparent material to make.Between upper cover plate (10) and the modular arc control device (12) mutually coupling be connected, connected mode is dismountable fixedly connected.Fixedly connected between irony lower cover (17) and the left and right sides pedestal (4), it is dismountable fixedly connected that connected mode is similarly.
Above the described description that provides most preferred embodiment, this embodiment has following advantage:
1. increase contact pressure, reduce contact resistance, increase clearance between open contacts, improve make-break capacity, improve useful life.
2. lever transmission mechanism adopts the transmission mechanism that has the arc keeper.Former lever is with the face contact form with contacting of adjustment screw, and this transmission mechanism is the horizontal disjunction of dynamic/static contact with the form of line contact, enhances product performance.
3. all insulation modular organization adopts the modular arc control device multistagely to make up, as one pole, two utmost points, two utmost points, four utmost points, five utmost points.
4. the structure uniqueness is rationally compact, good looking appearance, and volume is little.
