Abstract
The invention relates to a non-explosive capacitor. The non-explosive capacitor comprises a cylindrical metal outer shell, wherein a metal separation plate is arranged in an inner cavity of the metal outer shell, the metal separation plate and the inner wall of the metal outer shell are sealed, a sealed vacuum cavity is formed between the metal separation plate and the bottom of the metal outer shell, a circular pressing mark slot and a plurality of linear pressing marks are arranged in the center of the metal separation plate, and the linear pressing marks spread around along the edge of the pressing mark slot. As the metal separation plate is arranged, the vacuum cavity is formed between the metal separation plate and the bottom of the metal outer shell, the circular pressing mark slot and the linear pressing marks are arranged in the center of the metal separation plate, and the linear pressing marks spread around along the edge of the pressing mark slot, when the capacitor is used for a long period, internal pressure of the metal outer shell increases due to heating and causes an explosion, the circular pressing mark slot and the linear pressing marks explode directly due to weak spots, the vacuum cavity buffers internal pressure intensity, the outer shell is prevented from wholly exploding, electron components around the capacitor are effectively prevented from being damaged, maintenance cost is lowered, and resources are saved.
Description
Technical field
The present invention relates to capacitor technology field, relate in particular to a kind of noinductive capacitor.
Background technology
Capacitor is commonly referred to electric capacity, and electric capacity is also called " capacitance ", refers to the electric charge reserves under given potential difference, is designated as C, and international unit is farad (F).In general, electric charge is understood stressed and is moved in electric field, has had medium between conductor, has hindered electric charge move and make charge accumulation on conductor, causes the accumulation of electric charge to store, and the quantity of electric charge of storage is called electric capacity.Electric capacity is one of a large amount of electronic components that use in electronic equipment, is widely used in every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.
In prior art, capacitor, after long-time use, is easy to produce heat energy, and capacitor case, under the environment of high temperature, is easy to blast, in the moment of blast, is easy to make the impact that electronic devices and components are around exploded and damages, and causes whole circuit mixed bad.
Summary of the invention
In view of this, be necessary to provide a kind of noinductive capacitor that prevents from damaging the electronic devices and components of surrounding.
The present invention realizes like this, a kind of noinductive capacitor, comprise and be metal shell cylindraceous, in the inner chamber of described metal shell, be provided with metal partion (metp), between described metal partion (metp) and the inwall of metal shell, seal, and the vacuum chamber that forms sealing between metal partion (metp) and the bottom of metal shell, the distance between metal partion (metp) and the bottom of metal shell is 0.5 ~ 3cm, a plurality of wire impressions that the center of described metal partion (metp) is provided with circular impression groove and disperses to surrounding along the edge of impression groove.
Further, described vacuum chamber inside is provided with pressure inductor, and the lower surface of the bottom of described metal shell is provided with alarm, and described pressure inductor is electrically connected to alarm.
Further, described metal partion (metp) and metal shell are integrated.
The advantage of a kind of noinductive capacitor provided by the invention is: by metal partion (metp) being set in the inner chamber of metal shell, between metal partion (metp) and the bottom of metal shell, form vacuum chamber, and circular impression groove is set at the center of metal partion (metp), and a plurality of wire impressions of dispersing to surrounding along the edge of impression groove, after the long-time use of capacitor, owing to being heated, causing metal shell internal pressure to increase explodes, weak spot due to circular impression groove and wire impression, directly popped, setting due to vacuum chamber, relax inner pressure, prevent the blast of whole shell, effectively prevented the damage of capacitor electronic devices and components around, reduce maintenance cost, economize on resources.
