Abstract
The utility model discloses a kind of 10kV drop type fuse, wherein one end of two copper wires is equipped with copper clip, two copper clip connection fuse both ends are electrically connected to each other two copper wires and fuse, wherein the other end of a copper wire is fixed with the button cap connecting with equipment, and the other end of another copper wire is directly connect with equipment.It the utility model has the advantage of the mechanical strength that ensure that fuse, is not susceptible to be broken, improves the reliability of its work.
Description
Technical field
The utility model relates to fuse fields.
Background technique
10kV fuse switch is typically mounted at distribution transformer high-pressure side, to protect 10kV fixed track usage plan route not
It is influenced by distribution transformer failure, fuse switch is installed at rural area 10kV line end or lines branch and is protected
Shield.
Fuse switch is in normal closing position, and torque spring is tensioned fuse, to guarantee that fusion tube is reliably self-locking；Melt is molten
When disconnected, torque spring pulls out fuse rapidly to reduce arcing time and consumption arc quenching material；The upper end button cap of fuse is in fuse
When fusing under arcing, long-living pressure injection gas washes button cap open, forms the exhaust of fusion tube both ends.
Fuse switch fuse used at present is by circular solids copper pigtail sub-line, button cap, low melting point fuse sets
At copper pigtail sub-line with fuse, upper end button cap is connect with copper clip.This model when using low capacity fuse, fuse with
When drop type fusion tube connects, at fusion tube fuse corner and torque spring tensioning and the screw fixed point of end, it be easy to cause molten
Silk is stranded, or in power transmission, when fusion tube pushes up, to 45.When fuse be easy it is disconnected.
Summary of the invention
Technical problem to be solved in the utility model is to realize a kind of use reliable drop type fuse of safety and stability.
To achieve the goals above, the technical solution adopted in the utility model are as follows: a kind of 10kV drop type fuse, two copper
Wherein one end of silk is equipped with copper clip, and two copper clip connection fuse both ends make two copper wires and fuse mutually be electrically connected
It connects, wherein the other end of a copper wire is fixed with the button cap connecting with equipment, the other end of another copper wire is directly and equipment
Connection.
The copper wire is hollow netted copper wire.
The copper clip is hollow copper pipe, and the aperture of the copper pipe is slightly larger than fuse outer diameter.
The utility model has the advantage of the mechanical strength that ensure that fuse, it is not susceptible to be broken, improves its work
Reliability.
Detailed description of the invention
Below to width attached drawing every in the utility model specification expression content and figure in label be briefly described:
Fig. 1 is drop type fuse-wires structure schematic diagram；
Label in above-mentioned figure is equal are as follows: 1, button cap；2, copper wire；3, fuse；4, copper clip.
Specific embodiment
As shown in Figure 1,10kV drop type fuse includes two copper wires, 2, fuses 3, wherein one end of two copper wires 2 is equal
Equipped with copper clip 4, two copper clips 4, which connect 3 both ends of fuse, is electrically connected to each other two copper wires 2 and fuse 3, connects for convenience
Copper clip 4 is hollow copper pipe, and the aperture of copper pipe is slightly larger than 3 outer diameter of fuse, fuse 3 directly can be directly inserted into copper in this way
In pipe, relative, which clutches copper pipe, later makes its deformation, then fuse 3 reliably can be fixed on copper clip 4.
Wherein the other end of a copper wire 2 is fixed with the button cap 1 connecting with equipment, and the other end of another copper wire 2 is straight
It connects and is connect with equipment, the preferably hollow netted copper wire 2 of copper wire 2, hollow netted copper wire 2 is the copper mesh devalued by copper wire 2, then by copper
Net volume song constitutes hollow tubular structures, and hollow netted 2 light weight of copper wire, section is big, meets electric current skin effect, substantially increases
Mechanical strength, it is ensured that fuse 3 will not break at the corner of fusion tube and torque spring tensioning when fixing on fusion tube, netted sky
When fusion tube end screw is fixed, fuse 3 does not have to be directly inserted under screw washer with later from bolt and tightened spiral shell heart copper wire 2
Cap.
When the equipment or line failure that fuse switch is protected, since 3 mass of fuse lightens, even molten
Silk 3 long-living is beginning low current, and 3 upper end button cap 1 of fuse can also be opened in the long-living injection gas undershoot of electric arc, long-living both ends
Exhaust.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the utility model implements not by above-mentioned
The limitation of mode, as long as using the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out, or not
It is improved the conception and technical scheme of the invention are directly applied to other occasions, the protection scope of the utility model it
It is interior.
