In the present embodiment, such as Fig. 1 or 2 water, the both ends of plug-in strip 300 are respectively connected with moving contact 700, hook 800 by with lock
Knife 300 is connect with realizing with plug-in strip 300 close to 700 hanging buckle of the moving contact connection of 800 one end of hook.
In the present embodiment, fuse cutout includes: connection bolt (figure is unlabeled), and connection bolt passes through hook 800 and plug-in strip
Moving contact 700 close to hook one end, the moving contact 700 by hook 800 with plug-in strip 300 close to 800 one end of hook are connect, from
And it realizes and is connect with plug-in strip 300.
In the present embodiment, consider that plug-in strip 300 may be easy to cause local damage in some cases, therefore plug-in strip can be set
Two parts are set to, can also keep the flowing of electric current using another part after a part damage.
Specifically, as shown in fig. 6, plug-in strip 300 may include: the two panels insulation board 310 being oppositely arranged；It is arranged in insulation board
The two panels fuse piece 320 in 310 outsides, wherein the length of the fuse piece 320；Splitter between two panels insulation board 310 is set
330, the end thereof contacts of a splitter 330 wherein fuse piece 320, another another fuse piece 320 of end in contact.
Insulation board 310 can use SMC (Sheet molding compound) insulation board, with higher mechanical strong
Degree, anti-flammability, resistance to leakage property；Resistance to electric arc, dielectric strength and proof voltage are high, more preferably replace the porcelain in HR20 type in the prior art
Item improves the performance of plug-in strip 300.
Fuse piece 320 can be different according to different transformer rated current, select the fuse piece 320 of different size, prevent big
Rush of current electrical equipment, plays a protective role to electrical equipment.
Wherein, splitter 330 can form, respectively, first part and second part by two parts.First part and
Second part connects shape in an angle.One end of first part connects second part, another end in contact wherein a piece of fuse piece
320；Second part connects another fuse piece 320.Electric current is divided to two panels fuse piece by two parts.Further, first
It point can be with the identical plate structure of shape with second part.The top that first part connects the angle to be formed with second part can be with
Towards 310 one end of the first insulation column.
Referring to Fig. 1, fuse cutout can also include: the carbon brush component 900 being mounted on plug-in strip 300.
When splitting or integrating lock, when generating high current generation electric arc, carbon brush component 900 plays the role of arc extinguishing, protects fuse piece 320
And each components.
It is possible to further install multiple carbon brush components 900 on plug-in strip 300.
Fuse cutout provided in this embodiment may be implemented it is following the utility model has the advantages that 1, by decoupling device convenient for operator's drawing
The Push And Release of fuse cutout, it is apparent judge low pressure fusing whether in-place closing.2, by the way that plug-in strip 300 is arranged to two parts,
It is not easy to cause to have a power failure because porcelain vase item is broken by the component that two high-strength insulating plates 310 of setting and fuse piece 320 form.3, it melts
Disconnection pass is contacted using arch clip-type moving contact with copper sheet stronger.4, it when generating fuse wire situation, only needs to change single-phase
The dynamic touching operation of fuse cutout arch detachable type clip-type is fast and convenient.5, than the fuse cutouts such as old-fashioned HR20 type (low pressure switch with knifeshaped fuse)
It is lighter, convenient staff's transmitting and installation.6, convenient in transport, installation using handling property insulation column 200
In the process, be impacted breakage in operation, convenient replacement, avoids damaged a part of components, causes to replace a whole set of fuse cutout.
7,0.4kV arrester 420 can be installed, avoids transformer fault and lightning stroke etc. that high current is caused to cause the impact of metering device
Damage.8, high financial profit does not need a whole set of replacement, it is only necessary to more when damaging single-phase fuse cutout detachable type clip-type moving contact
It changes single-phase, greatlys save damage replacement cost.
The application also provides a kind of electrical equipment, and the electrical equipment in the present embodiment includes fuse cutout.
Fuse cutout in the present embodiment is similar to the fuse cutout in previous embodiment, can specifically refer to previous implementation
