Abstract
The invention discloses a direct current bus support capacitor of an electric automobile, which comprises a plastic housing, wherein a core assembly is arranged in the plastic housing, two binding posts are arranged on the upper end of the plastic housing, the two binding posts are connected with the core assembly inside the plastic housing through a connecting sheet respectively, and epoxy resin is packed on the external part of the welded place of the binding posts and the connecting sheet. The stray inductance of the direct current bus support capacitor of the electric automobile is effectively reduced due to the adoption of the connecting sheet with a square shape, and the current carrying capacity is greatly improved.
Description
Technical field
The present invention relates generally to the electric drive system field of new-energy automobile, relates in particular to a kind of electric automobile and uses dc bus support capacitor.
Background technology
Electric automobile of the prior art is used inner connection of dc bus support capacitor and is mainly adopted lead to connect.This method of attachment has strengthened electric automobile and has used the flow path that dc bus supports the capacitor internal current, and internal inductance has also just strengthened accordingly, and also little with the contact area at the two poles of the earth of electric capacity, is difficult to satisfy
New forms of energyNeed very low stray inductance and the ability of bearing very high peak voltage and surge current in the electric drive system.
Summary of the invention
The object of the invention is exactly in order to remedy the defective of prior art, to provide a kind of electric automobile to use dc bus and support capacitor.
The present invention realizes through following technical scheme:
A kind of electric automobile is used dc bus and is supported capacitor; Include and mould shell; Mould the core group is installed in the shell; Mould shell upper end and be provided with two binding posts, it is characterized in that: be connected through a brace respectively between the core group of described two binding posts and the inside of moulding shell, the outer enclosure of the weld of binding post and brace has epoxy resin.
Described epoxy encapsulation is being moulded on the shell, and binding post is positioned at the epoxy resin top, and the core group is positioned at the epoxy resin below.Described brace is the conductor of square sheet.
Principle of the present invention is:
The present invention is welded on electric automobile through the structure that adopts square sheet and uses between two binding posts that dc bus supports capacitor and the core group, has reduced the flow path of line current greatly, thereby has reduced the stray inductance of electric capacity inside.And effectively increased the contact area at electric capacity the two poles of the earth through the design of this square brace, the bearing capacity of electric current in the circuit is provided greatly.
Advantage of the present invention is:
The present invention adopts the brace of square sheet to effectively reduce electric automobile and uses the stray inductance that dc bus supports capacitor, has improved current carrying capacity greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
