An object of the utility model is to provide a good vacuum load switch of wear resistance, antiskid nature is with a vacuum is insulating cylinder for load switch.
Description
Technical field
The utility model relates to insulating boot, and more specifically, it relates to a kind of vacuum load switch insulation cylinder.
Background technology
Insulation covering is subject to widespread use in the industry field of power equipment; traditional vacuum load switch is provided with insulating boot; insulating boot mainly plays airtight effect; prevent electric arc from hurting human body; can effectively play insulation, provide protection, it is also possible to play the effect preventing dust from accumulating to a certain extent, but the insulating boot on traditional vacuum on-load switch is comparatively common; insulating boot is easy to be infected with, attract dust so that impaired performance own.
Disclosing the insulation cylinder that application number is the Chinese patent high-tension switch cabinet band Novel shielding structure of CN201420406495.3 in existing market, its insulating property are short of to some extent, are easily subject to external environment such as humiture, dust in addition, and this causes work-ing life shorter.
Practical novel content
For the deficiency that prior art exists, the purpose of this utility model is a kind of vacuum load switch insulation cylinder of vacuum load switch providing a kind of wear resisting property, anti-skid good.
For achieving the above object, the utility model provides following technical scheme:
A kind of vacuum load switch insulation cylinder, comprise cylinder, described cylinder comprises arc extinguishing portion and fixed installation portion, described arc extinguishing portion forms vacuum interrupter, described fixed installation portion is provided with the fixed installation hole for being connected with frame, described arc extinguishing portion is that corrugated tube is arranged, and the inwall in described arc extinguishing portion is provided with screen layer, and described screen layer comprises electromagnetic shielding cloth layer and semiconductive material coat.
By adopting technique scheme, by becoming, corrugated tube shape is arranged in the inside and outside portion of cylinder, effectively increase creepage distance, effectively utilize aerodynamic principle, accelerate gas circulation, effectively loose except heat, reduce temperature rise, work-ing life significantly improves, and the setting of electromagnetic shielding cloth layer can play anti-electrostatic, fire prevention, radioprotective, fire-retardant effect.
The utility model is set to further: the described cylinder back of the body is provided with dust layer to the one side of screen layer.
Pass through technique scheme so that cylinder has certain dirt exclusion capabilities, it is not easy to be stained with dust, it is possible to effectively avoid dust the performance of cover body to be had an impact.
The utility model is set to further: described dust layer adopts titanium dioxide fine particles to make, and described electromagnetic shielding cloth layer is at most 3mm.
Pass through technique scheme, titanium dioxide fine particles can have certain sun-proof ability, and be specially adapted to the indoor and outdoor texture coating to anti-pollution requirement is higher and use, use this product can not only strengthen self-cleaning function and the scrubbing resistance function of texture coating, greatly strengthen dust-proof, waterproof, the weather-proof ability of flexible texture coating.
The utility model is set to further: described semiconductive material coat is 1mm ~ 2mm.
The utility model is set to further: described cylinder adopts poured with epoxy resin shaping.
By technique scheme, not only use extensively, and low cost of manufacture.
The utility model is set to further: the thickness of described dust layer is 0.1cm.
By technique scheme, under the prerequisite saving most material, just can play the effect of expection.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vacuum load switch insulation cylinder embodiment of the utility model;
Fig. 2 is the structural representation at a kind of vacuum load switch insulation of the utility model another visual angle of cylinder embodiment.
In figure: 1, cylinder; 11, arc extinguishing portion; 12, fixed installation portion; 121, hole is fixedly mounted; 2, screen layer; 21, electromagnetic shielding cloth layer; 22, semiconductive material coat; 3, dust layer.
Embodiment
Referring to figs. 1 through Fig. 2, embodiment of the present utility model is described further.
Embodiment one: a kind of vacuum load switch insulation cylinder, comprise cylinder 1, described cylinder 1 comprises arc extinguishing portion 11 and fixed installation portion 12, described arc extinguishing portion 11 forms vacuum interrupter, described fixed installation portion 12 is provided with the fixed installation hole 121 for being connected with frame, described arc extinguishing portion 11 is arranged in corrugated tube, and the inwall in described arc extinguishing portion 11 is provided with screen layer 2, and described screen layer 2 comprises electromagnetic shielding cloth layer 21 and semiconductive material coat 22.
By adopting technique scheme, by becoming, corrugated tube shape is arranged in the inside and outside portion of cylinder 1, effectively increase creepage distance, effectively utilize aerodynamic principle, accelerate gas circulation, effectively loose except heat, reduce temperature rise, work-ing life significantly improves, and the setting of electromagnetic shielding cloth layer 21 can play anti-electrostatic, fire prevention, radioprotective, fire-retardant effect.
Described cylinder 1 is carried on the back the one side to screen layer 2 and is provided with dust layer 3. Pass through technique scheme so that cylinder 1 has certain dirt exclusion capabilities, it is not easy to be stained with dust, it is possible to effectively avoid dust the performance of cover body to be had an impact. Described dust layer 3 adopts titanium dioxide fine particles to make, and described electromagnetic shielding cloth layer 21 is at most 3mm. Pass through technique scheme, titanium dioxide fine particles can have certain sun-proof ability, and be specially adapted to the indoor and outdoor texture coating to anti-pollution requirement is higher and use, use this product can not only strengthen self-cleaning function and the scrubbing resistance function of texture coating, greatly strengthen dust-proof, waterproof, the weather-proof ability of flexible texture coating. Described semiconductive material coat 22 is 1mm ~ 2mm. Described cylinder 1 adopts poured with epoxy resin shaping.
By technique scheme, not only use extensively, and low cost of manufacture. The thickness of described dust layer 3 is 0.1cm. By technique scheme, under the prerequisite saving most material, just can play the effect of expection. This product is also referred to as fixed sealing type big current pole.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model. It is noted that for those skilled in the art, in the some improvements and modifications not departed under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
