Film and electric capacity installing plate are constituted.General producer installs between electric capacity, positive and negative busbar and positive and negative busbar on electric capacity installing plate
Big dielectric film after, do not carry out extra protective measure, but long-term after, due between positive and negative electrode because of a large amount of ash of deposition
Trifle in the world thing etc. and easily cause the security incidents such as capacitance component short circuit, blast, reduce the safety and reliability of inverter.
Utility model content
The purpose of this utility model is to provide a kind of insulation system for inverter bus capacitor assembly, and it has knot
Structure is simple, the feature of the security reliability of low cost and raising inverter, to solve inverter bus capacitor group in prior art
The problems referred to above that part exists.
For reaching this purpose, this utility model by the following technical solutions:
A kind of insulation system for inverter bus capacitor assembly, it includes electric capacity installing plate and is installed on described electricity
Hold several electric capacity on installing plate, wherein, outside the negative or positive electrode of several electric capacity described, be all cased with an insulator cap.
Especially, described insulator cap includes that cap body, described cap body are the cylindrical structure of hollow, the inner hole of institute's cap body
The external diameter of counter electrode is arranged, and the bottom of described cap body is outward extended with the brim of a hat of annular, the described the brim of a hat and described cap body
It is vertically arranged.
Especially, described cap body and the brim of a hat use PC integrated injection molding.
Especially, the top of described electric capacity is provided with ground floor dielectric film, being provided above of described ground floor dielectric film
Be placed on the cathode bus bar on electric capacity negative pole, described cathode bus bar be provided above second layer dielectric film, the described second layer insulate
Positive pole busbar it is cased with on film.
The beneficial effects of the utility model are, compared with prior art the described insulation for inverter bus capacitor assembly
It is cased with insulator cap outside the negative or positive electrode of the electric capacity of structure, adds the creep age distance between positive and negative electrode, and be effectively prevented
Dust and foreign material are piled up on positive and negative electrode, effectively ensure the insulation between positive and negative electrode, beneficially inverter bus capacitor group
The safety and reliability of part；And this insulative cap material low cost, it is simple to processing, easy to assembly.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of insulation system bag for inverter bus capacitor assembly
Including electric capacity installing plate 1 and several electric capacity 2 being installed on described electric capacity installing plate 1, the top of described electric capacity 2 is provided with
One layer of dielectric film 3, the cathode bus bar 4 being provided above being placed on electric capacity negative pole of described ground floor dielectric film 3, described negative pole is female
Row 4 is provided above second layer dielectric film 5, and described second layer dielectric film 5 is cased with positive pole busbar 6, several electric capacity described
Positive pole or/and be all cased with an insulator cap 7 outside negative pole.Described insulator cap 7 includes cap body 70, and described cap body 70 is the cylinder of hollow
Body structure, the external diameter of the inner hole counter electrode of institute's cap body 70 is arranged, and the bottom of described cap body 70 is outward extended with annulus
The brim of a hat 71 of shape, the described the brim of a hat 71 is vertically arranged with described cap body 70, and described cap body 70 and the brim of a hat 71 use high temperature resistant and bullet
The transparent PC integrated injection molding that property is good.
When inverter bus capacitor assembly is installed:
Step one: referring to shown in Fig. 1, first electric capacity 2 is arranged on electric capacity installing plate 1, then at electric capacity 2 top
Spreading ground floor dielectric film 3, now the positive and negative electrode of electric capacity 2 all exposes, and is then enclosed within cathode bus bar 4 on the negative pole of electric capacity 2
And dodge out the positive pole 8 of electric capacity, insulator cap 7 is placed on the positive pole 8 of described electric capacity 2, described cathode bus bar 4 offers cooperation
The through hole of the described the brim of a hat 71 external diameter.
Step 2: referring to shown in Fig. 2, then cover on cathode bus bar 4 with second layer dielectric film 5, and expose absolutely
The cap body 70 of edge cap 2, finally puts positive pole busbar 6.Offer on described positive pole busbar 6 and coordinate the logical of described cap body 70 external diameter
Hole.Now insulator cap 7 protects electric capacity negative pole the most well, adds the creep age distance of both positive and negative polarity, and effectively prevents because of dust heap
Amass and cause the risk of short circuit, enhance the safety of bus capacitor assembly.
Above example simply elaborates ultimate principle of the present utility model and characteristic, and this utility model is not by above-mentioned example
