Description
Technical field:
The utility model relates to a kind of fuses, more particularly, to a kind of fusing of fast semiconductor equipment protection
Device.
Background technique
Fuse is when electric current is beyond specified value, and the heat generated with itself makes one kind of melt fusing, disconnecting circuit
Electric appliance, in use, being series at fuse by protection circuit, when overloading or short circuit current passes through melt, melt itself will
It generates heat and fuses, to all play certain protective effect to electric system, various electrical equipments and household electrical appliance.At present
What can be seen in the market is used to protect frequency converter and IGBT (insulated gate bipolar transistor) fuse because of protection voltage requirement
Height, thus it is more complicated in structure and bulky, when voltage rating reaches 3000VDC or more, general volume length
All in 400mm or more, not only high material consumption in this way is at high cost, and transport, installation and use it is all inconvenient；And it is because molten
Only less than 0.05mm, length, directly through not being fixed in fusion tube, is produced, is transported all in 500mm or more body diameter
It is easy to break because of the external forces such as shaking, shaking, impacting, hitting, jolting in defeated, installation and use process, causes to report
It is useless.There are also the melts of some fuse mounted insides to pass through the processes such as production, transport, installation, although not breaking, because
By external force, melt is attenuated, and specified technical parameter requirement is just not achieved in use in this way, when withstanding voltage and
When the peak of equipment protection withstanding voltage and breaking current has not been reached yet in breaking current, because of the melt temperature liter at drawing-down
It is high and break, it powers off protected device in advance and stops working, increase the failure rate of equipment, affect the normal use of equipment
Effect, but also can be because equipment powers off in advance and can cause failure to equipment other in system or accident occurs.
Utility model content
In order to solve the above deficiency, simple, stable, function admirable that the purpose of this utility model is to provide a kind of structures,
Melt have passed through fixing process, and voltage rating bearing capacity can be effectively improved and to the breaking speed of false voltage, electric current and
The semiconductor equipment of breaking capacity protects supper-fast fuse, and melt length can reach 500mm or more, reach voltage rating
4000VDC, and volume length can be used to protect frequency converter and IGBT and other large-scale semiconductor equipments less than 150mm.
To achieve the above object, the utility model provides following technical solution:
1, a kind of DC voltage protects fuse up to 4000V fast semiconductor, including conductive contact, fusion tube, melt, molten
Body guide post, arc-extinguishing medium, pin and arc-extinguishing medium charging aperture, the melt guide post is by being reserved in the installation of conductive contact inner end
The conductive contact in hole and melt guide post both ends connects, and melt one end is connected with one end of welding manner and conductive contact
Come, be then wound around in the spiral groove on melt guide post, after being wound into end, then has connect with the other end with melt guide post
The conductive contact come welds, and so just constitutes the fusible core of fuse；
The conductive contact at the fusible core both ends and fusion tube, which are worn the position connect and applied in advance, spreads sealant, then passes through fusible core
Fusion tube wears with fusion tube set, and the pin hole by being reserved in conductive contact both ends and fusion tube both ends is fixed with pin, then
Arc suppression filling is loaded full arc extinguishing by being reserved in the arc suppression filling charging aperture of conductive contact one end to fill out between fusible core and fusion tube
Arc suppression filling charging aperture after the completion of filling, is blocked, so just constitutes fuse finished product by material with arc suppression filling capping.
2, spiral groove is provided on the melt guide post, convex portion can play the work for blocking arc spraying
With.
3, the arc extinguishing glue of fixed melt is coated between the melt being wrapped on melt guide post and melt guide post, simultaneously
This arc extinguishing glue can play the role of increasing arc quenching effect.
4, several metallurgical effect points are provided on the melt.
5, the conductive contact is copper silver-plated.
Melt is wrapped in melt and led by the utility model due to being provided with a melt guide post in the inner cavity of fuse fusion tube
In groove on column, both ends are welded with conductive contact again, and are applied between melt guide post and melt and spread arc extinguishing glue, can
So that melt is relatively securely fixed on melt guide post, good external force resistance can be played the role of, though production, transport,
Because shake, shake, impacting, hitting, jolting etc. by external force in installation and use process, it is also ensured that melt will not be broken
Or a part stress attenuates, and greatly improves the stability of fuse.
Since melt is spiral wrap on the melt guide post of fusion tube inner cavity, so, make the entire length of fuse
It greatly shortens, for common 3500VDC fuse currently on the market, length shortens nearly 2/3, and voltage rating etc.
Grade has also achieved 4000VDC, and material is saved, cost reduces, and installing and using space requirement also reduces.
The utility model on melt due to being equipped with metallurgical effect point, and the material melting point of metallurgical effect point is 150 DEG C~300
Between DEG C, the fusing time of melt can be efficiently controlled -- current characteristics prevents overcurrent from damaging.
The utility model is due to naturally forming protrusion corresponding with groove along the groove of spiral rotating on melt guide post
Part can play the role of blocking arc spraying.
The utility model is since the gap between fusion tube and fusible core is full of arc-extinguishing medium, the arc extinguishing when playing melt fusing
While, there is good heat sinking function in the case where permanent load electric current.
