Abstract
The invention discloses an inflatable pulse capacitor. The capacitor is characterized in that the capacitor mainly comprises a capacitor core, an insulation gas, a shell, an insulator casing pipe and an extraction electrode; the capacitor core is assembled in the shell; the insulator casing pipe is arranged on the shell; the insulation gas is arranged between the capacitor core and the shell. After improvement, through using the capacitor, an arc extinguishing capability of the capacitor, partial discharge of the capacitor, voltage withstanding of the capacitor, an insulation resistance of the capacitor and capacitor reliability can be increased. A product life can be prolonged. A volume and weight of the capacitor can be reduced. A secondary calamity after the capacitor is failed can be precluded.
Description
Technical field
The present invention relates to a kind of capacitor, especially a kind of gas-filled type pulse capacitor.
Background technology
Pulse capacitor can store a small-power power in long period interval to the rechargeable energy of capacitor, need certain in a flash, within the extremely short time interval, stored energy is discharged rapidly, form powerful impulse current and powerful percussion power.Be mainly used in the fields such as high-voltage test techniques, high-energy physics, laser technology, oscillation circuit, geological exploration.
The filler of present most of capacitor is: solid and liquid two class; Solid filler mainly contains: microwax, epoxy resin, black glue, polyurethane, silica gel etc.
The molecular diameter of solid filler is very large, poor fluidity is thickness very, pour into solid filler, basic filling is less than little gap and fuse inside, capacitor body inside and perfusion layer is made to there is a large amount of bubbles, cause partial discharge of capacitor starting voltage very low, make capacitor body self-healing too much, capacity declines and even punctures and lost efficacy too soon;
Liquid infiltration material mainly contains: vegetable oil (castor oil, rapeseed oil, soybean wet goods), methyl-silicone oil, mineral oil.
Metallized capacitor fuse winding tension is large, be wound around closely between rete, and oil molecule diameter is more much larger than gas molecule diameter, so oil equally soaks the inside less than fuse, gas is still had in the rete of fuse, the inner partial discharge inception voltage of fuse is low, and self-healing punctures, and capacity declines and still keeps away unavoidably.The maximum shortcoming of immersion oil product is: 1. the secondary disaster that can produce failure propagation after having oil product fault; 2. there is the risk of leakage of oil, contaminated environment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of gas-filled type pulse capacitor at this; Mainly comprise capacitor body, shell, insulator sleeve pipe and extraction electrode; Capacitor body assembling in the enclosure; Insulator sleeve pipe is arranged on shell, is full of insulating gas between capacitor body and shell; Capacitor arc extinguishing ability can be improved after improvement, improve partial discharge of capacitor, raising capacitor is withstand voltage, improve capacitor insulation resistance, improve capacitor reliability, extend the life-span of product; Reduce the volume and weight of capacitor, stop the secondary disaster after capacitor faults.
The present invention is achieved in that a kind of gas-filled type pulse capacitor of structure, it is characterized in that: mainly comprise capacitor body, shell, insulator sleeve pipe and extraction electrode; Capacitor body assembling in the enclosure; Insulator sleeve pipe is arranged on shell, is full of insulating gas between capacitor body and shell.
According to gas-filled type pulse capacitor of the present invention, it is characterized in that: shell is cylindrical, square, oval, isogonism hexahedron, isogonism eight limit body, tubular body, halfpipe body.
According to gas-filled type pulse capacitor of the present invention, it is characterized in that: gas-filled type pulse capacitor sleeve pipe quantity can be single sleeve pipe, double-jacket tube, many sleeve pipes.
According to gas-filled type pulse capacitor of the present invention, it is characterized in that: gas-filled type pulse capacitor sheathing material can be metal material or insulating material two kinds.
According to gas-filled type pulse capacitor of the present invention, it is characterized in that: insulating gas is insulating gas or the inert gases such as SF6, N2, g3.
SF6 gas arc extinguishing is very capable, it is 100 times of air, withstand voltage is 3 times of air, and SF6 gas molecule diameter is very little, makes the packing material of pulse capacitor of SF6 gas, in the rete that SF6 gas can be made to pour into fuse fully and in all clearance for insulations of capacitor, to the partial discharge field intensity improving capacitor, improve arc extinguishing ability, reduce capacitors self-healing probability, improve the effect of life of product clearly.Utilize the anti-flammability of SF6 gas, the problem of the secondary disaster that may occur after can stopping capacitor faults; Use SF6 gas can also reduce volume, weight reduction.
The invention has the advantages that: the present invention provides a kind of gas-filled type pulse capacitor by improvement, mainly comprise capacitor body, shell, insulator sleeve pipe and extraction electrode; Capacitor body assembling in the enclosure; Insulator sleeve pipe is arranged on shell, is full of insulating gas between capacitor body and shell; Capacitor arc extinguishing ability can be improved after improvement, improve partial discharge of capacitor, raising capacitor is withstand voltage, improve capacitor insulation resistance, improve capacitor reliability, extend the life-span of product; Reduce the volume and weight of capacitor, stop the secondary disaster after capacitor faults.
