Description
Technical field：
It the utility model is related to capacitor technology field, and in particular to a kind of GTO snubbers capacitor.
Background technology：
Capacitor, it is electric capacity that generally referred to as it, which accommodates the ability of electric charge, is represented with letter C.Define 1：Capacitor, Gu Mingsi
Justice, it is ' container of dress electricity ', is a kind of device for accommodating electric charge.Capacitor be the electronic component that is largely used in electronic equipment it
One, the separated by direct communication being widely used in circuit, couple, bypass, filtering, resonant tank, energy conversion, control etc..It is fixed
Justice 2：Capacitor, any two is insulated from each other and the conductor (including wire) that is spaced closely together between all form a capacitor.
GTO (gate level turn-off thyristor), it is a kind of power electronic devices.It is applied to GTO capacitor shock resistance at present
It is poor with interference free performance.
Utility model content：
Technical problem to be solved in the utility model is to overcome existing technological deficiency, there is provided a kind of GTO bufferings are inhaled
Current condenser.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of GTO snubbers capacitor, including turned to using metallized polypropylene film capacitor body, two sprays
Layer gold, two contact conductors, housing, two gilding layers are sprayed at the both ends of capacitor body respectively, and housing is wrapped in capacitor body
Outside gilding layer, the contact conductor bottom is absorbed in housing wall, and two gilding layers are connected to two contact conductors by spring respectively,
The housing exterior walls copper facing.
Heat conductive flame-retarding epoxy resin is filled with the housing.Heat-conduction epoxy resin has the function that the flame proof that radiates, and it hinders
Combustion property is good.
The contact conductor is coated with flame retardant epoxy powder bed.Flame retardant epoxy powder can protect lead, prevent that its is short
Road is on fire.
The outer wall copper facing of the flame retardant epoxy powder bed.
The housing bottom gluing has a fin for passing through out housing, the fin be provided with skewed and fin it is logical
Hole.Fin make it that radiating is more preferable.
The fin is corrugated surface and corrugated surface side wall is pressed with impression.
The beneficial effects of the utility model are：Spring can be with buffer condenser fuse pressure when excessive turgor pressure, housing
Outer wall copper facing, which can shield extraneous electric current, to be influenceed so that capacitor using effect is more preferable；And the capacitor self-induction is small, equivalent series
Resistance is low；It is lost that small, insulaion resistance is high；High voltage, heavy current impact can be born；High DV/DT values, it is mainly used in high voltage, big
In electric current, high impulse circuit.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in drawings, a kind of GTO snubbers capacitor, including turned to using metallized polypropylene film
Cylindrical capacitor fuse 1, two gilding layers 2, two contact conductors 3, housing 4, two gilding layers 2 are sprayed at capacitor body 1 respectively
Both ends, housing 4 is wrapped in outside capacitor body 1 and gilding layer 2, and the bottom of contact conductor 3 is absorbed in the wall of housing 4, two gilding layers 2
Two contact conductors 3, the outer wall copper facing of housing 4 are connected to by spring 5 respectively.
Heat conductive flame-retarding epoxy resin 6 is filled with housing 4.Heat-conduction epoxy resin has the function that the flame proof that radiates, and its is fire-retardant
Property is good.
Contact conductor 3 is coated with flame retardant epoxy powder bed.Flame retardant epoxy powder can protect lead, prevent its short circuit from rising
Fire.
The outer wall copper facing of flame retardant epoxy powder bed.
The bottom gluing of housing 4 has the fin 7 for passing through out housing 4, and fin is to be provided with through hole on skewed and fin.Dissipate
Backing make it that radiating is more preferable, is obliquely installed so that area of dissipation is bigger.
Fin 7 is corrugated surface and corrugated surface side wall is pressed with impression.Improve radiating effect.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
