Abstract
The utility model discloses a permanent magnetic operating vacuum circuit breaker isolator combined electrical apparatus, permanent magnetic operating vacuum circuit breaker isolator combined electrical apparatus includes auxiliary switch, permanent magnetic mechanism, mechanism's case, frame, isolation sword, keeps apart sword blade, solid utmost point post and insulating pull rod. The utility model discloses a superior effect lies in: the permanent magnetic operating vacuum circuit breaker isolator combined electrical apparatus circuit breaker organically makes up as an organic wholeization product with isolator, not only makes the structure more tend to reasonable, compact, and the more important thing can reduce the quantity of spare part, improves reliability of an item, not only has the function of sky circuit breaker, still has isolator's function.
Description
Technical field
The utility model relates to iec switch field, is specifically related to a kind of permanent magnetic operating vacuum circuit-breaker isolating switch combined electrical apparatus.
Background technology
" vacuum circuit-breaker " gains the name because the dielectric of contact gap after its arc-extinguishing medium and arc extinguishing is all high vacuum; It has volume little, lightweight, be applicable to frequent operation, advantage that arc extinguishing need not overhaul, apply comparatively universal in power distribution network.Vacuum circuit-breaker is 3 ~ 10kV; indoor distribution in 50Hz three-phase alternating current system; can in industrial and mining enterprises, power plant, transformer station as the protection of electric equipment and control; be specially adapted to the field of employment requiring non-oil ultra high vacuum system, less maintenance and frequent operation; circuit breaker is configurable in middle-placed switch cabinet, double-layer cabinet, fixing cabinet and uses as control and protection high voltage electric equipment; but vacuum circuit-breaker of the prior art only have traditional to cut-off, defencive function; cannot isolating switch insulating power supply, so have the space of improvement.
Utility model content
The utility model provides a kind of permanent magnetic operating vacuum circuit-breaker isolating switch combined electrical apparatus, with solve existing vacuum circuit-breaker only have traditional to cut-off, defencive function, cannot the technical problem of isolating switch insulating power supply.
A kind of permanent magnetic operating vacuum circuit-breaker isolating switch combined electrical apparatus, described permanent magnetic operating vacuum circuit-breaker isolating switch combined electrical apparatus comprises auxiliary switch, permanent magnet mechanism, mechanism case, framework, isolation knife, isolation knife blade, pole and insulated tension pole, described mechanism case is positioned at the left side of described framework, described permanent magnet mechanism is positioned at described mechanism case, described auxiliary switch is positioned at one end of described permanent magnet mechanism, described pole is positioned at the right side of described framework, described isolation knife blade is positioned at the upper end of described pole, described permanent magnet mechanism comprises lower yoke, coil, permanent magnet, moving armature, upper magnet yoke, hand split axle, outer yoke, sluice separating spring and connector.
After employing technique scheme, the utility model permanent magnetic operating vacuum circuit-breaker isolating switch combined electrical apparatus circuit breaker and isolating switch being organically combined into one product, structure is not only made more to be tending towards reasonable, compact, the prior quantity that can reduce parts, improve the reliability of product, not only there is the function of sky circuit breaker, also there is the function of isolating switch.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the topology view of the utility model permanent magnetic operating vacuum circuit-breaker isolating switch combined electrical apparatus;
Fig. 2 is the topology view of permanent magnet mechanism.
Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 to Figure 2, a kind of permanent magnetic operating vacuum circuit-breaker isolating switch combined electrical apparatus comprises auxiliary switch 1, permanent magnet mechanism 2, mechanism case 3, framework 4, isolation knife 5, isolation knife blade 6, pole 7 and insulated tension pole 8, described mechanism case 3 is positioned at the left side of described framework 4, described permanent magnet mechanism 2 is positioned at described mechanism case 3, described auxiliary switch 1 is positioned at one end of described permanent magnet mechanism 2, described pole 7 is positioned at the right side of described framework 4, described isolation knife blade 6 is positioned at the upper end of described pole 7, described permanent magnet mechanism 2 comprises lower yoke 9, coil 10, permanent magnet 11, moving armature 12, upper magnet yoke 13, hand split axle 14, outer yoke 15, sluice separating spring 16 and connector 17.
When breaker main shaft receives combined floodgate order, coil 10 passes to forward current instantaneously, the electromagnetic field that coil 10 is produced and the permanent magnetic field Downward addition of permanent magnet 11, its electromagnetic force makes moving armature 12 do adhesive campaign, make breaker closing, and make moving armature 12 and lower yoke 9 firmly adhesive by the suction of permanent magnetic field, achieve combined floodgate stable state and keep.When circuit breaker obtains separating brake instruction, coil 10 passes to reverse current instantaneously, the permanent magnetic field that the electromagnetic field that coil 10 is produced and permanent magnet 11 produce inversely adds, closing retention force is fallen sharply, forceful action is synthesized again by touch spring and separating brake extension spring, make circuit breaker quick acting switching-off, when moving armature 12 moves to open position, the suction of permanent magnetic field makes its separating brake stable state keep.
The utility model permanent magnetic operating vacuum circuit-breaker isolating switch combined electrical apparatus circuit breaker and isolating switch being organically combined into one product, structure is not only made more to be tending towards reasonable, compact, the prior quantity that can reduce parts, improve the reliability of product, not only there is the function of sky circuit breaker, also there is the function of isolating switch.
Last it is noted that above embodiment only illustrates the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
