Filter apparatus and frequency coverter to which the filter apparatus is connected

Abstract

A power converter connected to a wiring drawing portion of a frequency converter, said filter apparatus including: a condenser element having an electronic part having an insulator as a dielectric material held between conductor plates; a sealing agent sealing said condenser element; a filter circuit comprising said condenser element; a connection conductor establishing wiring connections of said filter circuit; and a filter housing supporting said sealing agent.

1 . A power converter connected to a wiring drawing portion of a frequency converter, said filter apparatus comprising:
 a condenser element having an electronic part having an insulator as a dielectric material held between conductor plates;   a sealing agent sealing said condenser element;   a filter circuit comprising said condenser element;   a connection conductor establishing wiring connections of said filter circuit; and   a filter housing supporting said sealing agent;   wherein said filter apparatus is fixed to said frequency converter based on a positioning portion provided in part of the housing of said frequency converter.   
   
   
       2 . The power converter according to  claim 1 , wherein the raised portion provided in said filter apparatus is interlocked with a hole-like positioning portion provided in part of the housing of said frequency converter to position said filter apparatus in said frequency converter. 
   
   
       3 . The power converter according to  claim 1 , wherein said filter apparatus is abutted against a step-like positioning portion provided in part of the housing of said frequency converter to position said filter apparatus in said frequency converter. 
   
   
       4 . The power converter according to  claim 1 , wherein an adhesive is used to fix said filter apparatus to the housing of said frequency converter. 
   
   
       5 . The power converter according to  claim 1 , wherein a screw is used to fix said filter apparatus to the housing of said frequency converter. 
   
   
       6 . The power converter according to  claim 1 , wherein a Hook-and-Loop is used to fix said filter apparatus to the housing of said frequency converter.
