Abstract
The invention discloses a firing and explosion prevention high voltage capacitor, comprising a metal enclosed shell (6) and a shell cover component (2) with two exterior connection terminals (1); the shell (6) is internally provided with a set of capacitor cores connected in parallel and series; the two connection ends (8) of the capacitor core set are respectively connected with the two exterior connection terminals (1) by lead wires (4); the shell (6) is filled with steeping fluid (9) which is 330 methyl silicone oil; and the middle part of the shell (6) is provided with an annular groove (5) arranged in circumferential direction along the shell (6). With the above structure adopted, as the steeping fluid in the capacitor is 330 methyl silicone oil, the flaming-free property ensures that the capacitor can not fire or explode when the electric quantity is too large or the capacitor leaks; meanwhile the capacitor can be bound on other parts by the annular groove to avoid falling off during use.
Description
Technical field
The present invention relates to a kind of power capacitor, specifically is a kind of firing and explosion prevention high voltage capacitor special-purpose in the oil drilling platform that is applicable to.
Background technology
Power capacitor is important assembly in the system that is used for electric power conveying and distribution; In the oil drilling platform, can use the high-voltage alternating electric power capacitor of metalized film polypropylene media; Because need at sea to work continuously for a long time, operating environmental condition is very abominable.Capacitor constitutes by paper film and oil clearance the shell insulation in the prior art.The shortcoming below but this capacitor exists:
1. because the environment for use of this capacitor is underground below 1500 meters; Severity requires very high; Therefore when in case capacitor makes the inner electric weight of capacitor too high because of improper use, the phenomenon of under "on" position, can blast, burning, thus cause the generation of security incident.
2. again because capacitor is mounted on the drill bit of oil drilling machine, not have fixing structure on the capacitor, so be easy to fall down from drill bit.
Summary of the invention
Technical problem to be solved by this invention is, can cut off the power supply automatically when a kind of hypertonia is provided, and prevents capacitor blast, burning, thereby reduces the security incident incidence and firm firing and explosion prevention high voltage capacitor is installed.
For solving the problems of the technologies described above; A kind of firing and explosion prevention high voltage capacitor provided by the invention comprises metal enclosed shell, has the cap assembly of two external connection terminals, be equipped with in the described shell through also, series capacitors core group; Two terminals of described capacitor core group are connected through lead with two external connection terminals respectively; Described enclosure is full of maceration extract, and described maceration extract is No. 330 methyl-silicone oils, and described shell middle part is provided with the annular groove that circumferentially is provided with along shell; Described capacitor core group is divided into three unit fuses, and wherein two unit fuse parallel connections are positioned at the bottom of capacitor, and the 3rd unit fuse and preceding two unit fuse coupled in series are positioned at the middle part of capacitor; Described annular groove is between parallelly connected fuse group and series connection fuse.
After adopting above structure; The present invention compared with prior art; Have following advantage: 1) because the inner maceration extract of capacitor is No. 330 methyl-silicone oils, the incombustible that itself has make capacitor electric weight takes place can combustion explosion when too high or during capacitor leakage yet; Simultaneously, capacitor can utilize annular groove to be bundled on the miscellaneous part, prevents that capacitor from use falling down.2) after this series-parallel draw bail of employing, tandem energy plays the effect of dividing potential drop, makes capacitor can store more electric energy, and two unit fuses parallel connection separations of bottom can reduce the rising of temperature in the capacitor in the use of capacitor.Separated internal capacitor fuse group in addition, avoided Yin Wendu to raise and cause the phenomenon of product punch through damage, thus life-saving.
As further improvement; Described cap assembly lower end is provided with explosion-proof; Two leads of described capacitor core group are welded on the outside of explosion-proof last two through wires holes respectively, and the free end that respectively stretches out the lead of through wires hole welds with the bottom of two external connection terminals respectively.Owing to link together through explosion-proof two wiring conductor wire end and two external connection terminals capacitor core group in cap assembly bottom; Promptly there is a trifle lead to be positioned at explosion-proof; Its two ends are welded on binding post bottom surface and explosion-proof surface respectively; When the electric weight in the capacitor is too high, outer casing top surface is heaved, the lead in explosion-proof ruptures under the effect of two ends pulling force, and this moment, electric current was obstructed; Reach the purpose of capacitor outage, thereby solved that capacitor is blasted and the security incident that causes burning.
Described welding is meant the welding of after adding tin point on the solder joint, carrying out manual welding.Generally in the prior art adopt the machine welding, be easy to weldering like this and cause the atrophy of being heated of medium end face, thereby capacitor was lost efficacy, adopt this add the manual welding of tin point after, the rosin joint of solder joint is little, adhesive force is good.
Described shell is an aluminum.Shell is generally ironly in the prior art, plates the very thin aluminium lamination of one deck more outside, is easy to corrosion.After adopting aluminium shell, under the environment harsh conditions, also be difficult for being corroded.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done explanation in further detail.
Structural representation by the anti-flaming high-voltage capacitor of the present invention shown in the drawings can be known; It comprises metal enclosed shell 6, has the cap assembly 2 of two external connection terminals 1; Be equipped with in the described shell 6 through also, series capacitors core group, two terminals 8 of described capacitor core group are connected through lead 4 with two external connection terminals 1 respectively.Described shell 6 inside are full of maceration extract 9, and described maceration extract 9 is No. 330 methyl-silicone oils.Described shell 6 middle parts are provided with the annular groove 5 that circumferentially is provided with along shell 6.Described shell 6 is an aluminum.
Described capacitor core group is divided into three unit fuses, and wherein two unit fuse parallel connections are positioned at the bottom of capacitor, and the 3rd unit fuse and preceding two unit fuse coupled in series are positioned at the middle part of capacitor; Described annular groove 5 is between parallelly connected fuse group and series connection fuse.
Described cap assembly 2 lower ends are provided with explosion-proof 3 (being generally the commercially available prod); Two leads 4 of described capacitor core group are welded on the outside of two through wires holes 7 on explosion-proof 3 respectively, and the free end that respectively stretches out the lead 4 of through wires hole 7 welds with the bottom of two external connection terminals 1 respectively.Described welding is meant the welding of after adding tin point on the bond pad locations, carrying out manual welding.
When capacitor in use because a variety of causes is when sharply increasing electric weight in the shell, the aluminium skin of shell 6 end faces is just toward external drum; Lead 2 in causing explosion-proof 3 receives the effect of pulling force; Because an end of this section lead is welded on the bottom surface of binding post 1, the other end is welded on explosion-proof 3 surface, is limited by in two ends; Lead can rupture as a result, and the capacitor outage is not worked.
