Description
Technical field
The utility model relates to capacitor technology field, particularly relates to a kind of noinductive capacitor.
Background technology
Capacitor, being usually called for short its ability holding electric charge is electric capacity, represents by letter C.Definition 1: capacitor, as the term suggests being ' container of dress electricity ', is a kind of device holding electric charge.English name: capacitor.Capacitor is one of a large amount of electronic component used in electronic equipment, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.Definition 2: capacitor, any two insulated from each other and all form a capacitor between the conductor (comprising wire) of being separated by very near.
Electric capacity is different from capacitor.Electric capacity is fundamental physical quantity, symbol C, and unit is F (farad).
The special formula of general formula C=Q/U plane-parallel capacitor: electric field strength E=U/d between plate, condenser capacitance determines formula C=ε S/4 π kd
Along with making rapid progress of electronic information technology, the update speed goes of digital electronic goods is fast, based on the consumer electronics product volume of production and marketing sustainable growth of the products such as panel TV (LCD and PDP), notebook computer, digital camera, capacitor industry has been driven to increase.And having driven the development of associated materials, equipment Industry, China has become global capacitor big producing country.
In prior art, large-scale capacitor device, in the long-time process used, is easy to produce heat energy, is easy to generation quick-fried in vain, thus causes other electronic devices and components around capacitor to be damaged by it, thus the resource of large losses and cost.
Utility model content
In view of this, the noinductive capacitor providing a kind of electronic devices and components preventing from being in capacitor surrounding to damage is necessary.
The utility model realizes like this, a kind of noinductive capacitor, comprise capacitor case, also comprise metal protection layer and explosion-proof layer, described metal protection layer wraps up described capacitor case, and forms one deck vacuum layer between capacitor case and metal protection layer, described explosion-proof layer wraps up described metal protection layer, between described explosion-proof layer and metal protection layer, there is cavity, in described cavity, be full of fine sand, between described metal protection layer and explosion-proof layer, be provided with multiple dowel.
Further, described capacitor case, metal protection layer and explosion-proof layer are coaxial.
Further, described multiple dowel is all in cavity, and is uniformly distributed, and one end of described dowel is fixed on the outer wall of metal protection layer, and the other end is fixed on the inwall of explosion-proof layer, and the angle of dowel and vertical direction is 30 °.
The advantage of a kind of noinductive capacitor that the utility model provides is: the utility model is simple and reasonable, by arranging metal protection layer and explosion-proof layer, described metal protection layer wraps up described capacitor case, and between capacitor case and metal protection layer, form one deck vacuum layer, described explosion-proof layer wraps up described metal protection layer, between described explosion-proof layer and metal protection layer, there is cavity, fine sand is full of in described cavity, multiple dowel is provided with between described metal protection layer and explosion-proof layer, dowel has fixing effect, in the process used, after the blast of capacitor case expanded by heating, vacuum layer has certain cushioning effect, air in the capacitor case that dilution is expanded, reach explosion-proof effect, and explosion-proof layer protects the fragment of internal explosion to pass on the electronic devices and components of capacitor surrounding further, the safety of the surrounding electronic devices and components of effective protection, thus saved great amount of cost and resource.
