REACTOR, METHOD FOR PRODUCING REACTOR, CONVERTER, AND POWER CONVERSION DEVICE

摘要

The present invention relates to a reactor (1A) provided with: coils (2) of winding wire wound into helical shape; and magnetic cores (3) arranged inside and outside of the coils (2) and forming a closed magnetic circuit. The reactor (1A) is furnished with a insulating partial covering (2C) formed on a portion of the coils (2), at a location constituting the installation-facing side of the coils (2) when the reactor (1A) is installed on an installation target. In locations apart from the location at which the partial insulating covering (2C) is provided, the insulating covering is either substantially absent, or thin and cursory.
