Abstract
A kind of outdoor vacuum primary cut-out.Mainly solve present outdoor vacuum primary cut-out and be mostly furnished with the keying that operating grip carrys out Non-follow control circuit breaker, but easily there is the problem that cannot disconnect that lost efficacy after a number of uses in operating grip.It is characterized in that: bottom described insulated connecting rod, be connected with body cradle, described body cradle is by connecting shaft and described operating grip synchronous hunting, also pull bar is connected with bottom described body cradle, described pull bar is provided with chute, also rotation axis is provided with in described holder, described rotation axis is provided with projection, and described projection is located in chute.The utility model provides a kind of outdoor vacuum primary cut-out, except operating grip, further comprises rotation axis, rotation axis is connected with pull bar, pull bar drives body cradle, and then drives insulated tension pole to drive isolating switch, can be realized the disconnection of circuit breaker under operating grip failure conditions by rotation axis, structure is simple, use safety.
Description
Technical field
The utility model belongs to field of circuit breakers, particularly a kind of outdoor vacuum primary cut-out.
Background technology
Along with improving constantly of vacuum circuit-breaker technical merit, vacuum circuit-breaker is as the switching device controlling and distribute electric energy, and be more and more widely used in electric power system, use department it is also proposed higher requirement to vacuum circuit-breaker.Vacuum circuit-breaker is gained 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.Primary cut-out, when overhauling or segmentation has a power failure, guarantee circuit breaker and leading-out terminal power-off, can cut-off realization by circuit breaker.Present outdoor vacuum primary cut-out is furnished with the keying that operating grip carrys out Non-follow control circuit breaker mostly, but the problem that cannot disconnect that lost efficacy easily appears in operating grip after a number of uses.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of outdoor vacuum primary cut-out, mainly solve present outdoor vacuum primary cut-out and be mostly furnished with the keying that operating grip carrys out Non-follow control circuit breaker, but easily there is the problem that cannot disconnect that lost efficacy after a number of uses in operating grip.
The technical scheme that the utility model adopts is:
A kind of outdoor vacuum primary cut-out, comprise holder, described holder is provided with pole, isolating switch, current transformer and operating grip, described current transformer is arranged on described pole, described isolating switch one end is corresponding with current transformer, the other end is provided with insulated connecting rod, body cradle is connected with bottom described insulated connecting rod, described body cradle is by connecting shaft and described operating grip synchronous hunting, also pull bar is connected with bottom described body cradle, described pull bar is provided with chute, also rotation axis is provided with in described holder, described rotation axis is provided with projection, described projection is located in chute.
The employing integrated injection molding of described pole.
Described pole is made up of methyl vinyl silicone rubber.
Described pole and described insulated connecting rod are all arranged with silicone rubber sleeve, and described silicone rubber sleeve is provided with external shed.
Described external shed comprises the larger large full skirt of diameter and the less little full skirt of diameter, described large full skirt and little full skirt with pole axle center for axis is uniform staggered with.
The beneficial effects of the utility model are: the utility model provides a kind of outdoor vacuum primary cut-out, except operating grip, further comprises rotation axis, rotation axis is connected with pull bar, pull bar drives body cradle, and then drives insulated tension pole to drive isolating switch, can be realized the disconnection of circuit breaker under operating grip failure conditions by rotation axis, structure is simple, use safety.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model embodiment.
Fig. 2 is Figure 1A place enlarged drawing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in the figure, a kind of outdoor vacuum primary cut-out, comprise holder 9, described holder 9 is provided with pole 1, isolating switch 2, current transformer 3 and operating grip 4, described current transformer 3 is arranged on described pole 1, described isolating switch 2 one end is corresponding with current transformer 3, the other end is provided with insulated connecting rod 5, body cradle 6 is connected with bottom described insulated connecting rod 5, described body cradle 6 is by connecting shaft and described operating grip 4 synchronous hunting, pull bar 7 is also connected with bottom described body cradle 6, described pull bar 7 is provided with chute 71, rotation axis 11 is also provided with in described holder 9, described rotation axis 11 is provided with projection 12, described projection 12 is located in chute 71.When rotation axis rotates, (in figure direction) pull bar can be pulled to the right, pull bar rotates at drive body cradle, and then drive insulated connecting rod to promote isolating switch, circuit breaker is disconnected, here rotation axis can be manual, also can be connected with the tripping mechanism in pole, the utility model provides a kind of outdoor vacuum primary cut-out, except operating grip, further comprises rotation axis, rotation axis is connected with pull bar, pull bar drives body cradle, and then drive insulated tension pole to drive isolating switch, the disconnection of circuit breaker can be realized by rotation axis under operating grip failure conditions, structure is simple, use safety.
In the utility model, as shown in the figure, the employing integrated injection molding of described pole 1.Easy to process, result of use is good.
In the utility model, as shown in the figure, described pole 1 is made up of methyl vinyl silicone rubber.Methyl vinyl silicone rubber high-and low-temperature resistance, can long-term work at-50 ~ 250 DEG C, moistureproof, electrical insulating property, and resistance to electric arc is corona resistant.Ageing-resistant, ozone resistance.Surface is viscosity and hydrophobicity not.Compression is little, resistance to saturated steam.
In the utility model, as shown in the figure, described pole 1 and described insulated connecting rod 5 are all arranged with silicone rubber sleeve, and described silicone rubber sleeve is provided with external shed.
In the utility model, as shown in the figure, described external shed comprises the larger large full skirt 14 of diameter and the less little full skirt 15 of diameter, described large full skirt 14 and little full skirt 15 with pole 1 axle center for axis is uniform staggered with.Owing to there is spaced large and small cluster parachute, not vulnerable to pollution, not easily forms the curtain of rain, improves insulating properties, hydrophobicity and self-cleaning, and uniform being more prone to is processed, and result of use is breathed out
Embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection range of the present utility model.
