Abstract
The utility model discloses a protective device, and especially discloses a protective device for a drop-out fuse. An object of the utility model is to provide the protective device, which has good safety performance and high-temperature resistance, for the drop-out fuse. A fiberglass layer is disposed outside a ceramic tube. The protective device has the advantages of simple structure, good using effect and good safety.
Description
Technical field
The utility model relates to a kind of protective device, and is especially a kind of for the protective device on the fuse switch.
Background technology
Fuse switch is the most frequently used a kind of protective switch of the short circuit of 10kV distribution line branch line and distribution transformer, it have economy, easy to operate, adapt to characteristics such as outdoor environment is strong; Be widely used in 10kV distribution line and distribution transformer primary side as protection and carry out the usefulness that equipment is thrown, cut operation.
The protective device that is used on the fuse switch is earthenware at present; because shortcoming such as that earthenware has is wear-resisting, anti-corrosion, heat resistance is good; therefore can be widely used in industries such as electric power, metallurgy, mine, coal, chemical industry as carrying grindability granule materials and Korrosionsmediums such as sand, stone, coal dust, lime-ash, aluminium liquid, be a kind of desirable erosion resistant, high temperature resistant pipeline.
The phenomenon but earthenware can be blasted under certain high temperature, thus there is certain potential safety hazard.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of security performance good, resistant to elevated temperatures for the protective device on the fuse switch.
In order to achieve the above object, the utility model is designed is used for protective device on the fuse switch, is provided with fiberglass layer outside earthenware.
As preferably, the thickness of fiberglass layer is 2-20mm.
During making, outside earthenware, twine fiberglass layer, form tubular body.
The utility model gained be used for protective device on the fuse switch; be provided with fiberglass layer in original earthenware outside; temperature that can't stand fuse switch when earthenware will explosion time; be provided with the reason of fiberglass layer owing to the outside; make that protective device can be high temperature resistant to 1800 ℃; the fiberglass layer outer surface begins slowly to melt, and the staff needs only pipe is taken off from new replacing, thereby plays the safeguard protection effect.Thereby, it have simple in structure, result of use good and safety etc. characteristics.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, present embodiment is described is used for protective device on the fuse switch, is provided with fiberglass layer 2 outside earthenware 1, and the thickness of fiberglass layer 2 is 10mm.
Claims (2)
1. a protective device that is used on the fuse switch is characterized in that: be provided with fiberglass layer (2) outside earthenware (1).
2. according to claim 1 a kind of for the protective device on the fuse switch, it is characterized in that: the thickness of fiberglass layer (2) is 2-20mm.
