この種リアクトルの騒音の一因となつていた。 Incidentally, the vibration of such a gapped iron-core reactor is caused more by the vibration of the block iron core 1- in the gap part of the magnetic path where the gap spacer 2 is arranged than the magnetostrictive vibration of the iron cores such as the block iron core 1 and the yoke 4. The force generated by the magnetic attraction between the two is larger. For this reason, conventionally, the gap spacer 2 is made of, for example, porcelain, which is hard and has a large Young's modulus, and has a structure that suppresses the amplitude of vibration caused by the magnetic attraction force. However, a hard material with a large Young's modulus also has good vibration transmittance, so it transmits the vibration of the leg core 3 well to the yoke 4, and further transmits it to the container wall through, for example, a core clamping fitting (not shown).
This was a contributing factor to the noise of this type of reactor.
この発明は上述の点に鑑み、この種ギヤツプ付

減するようにしたものである。 In view of the above-mentioned points, this invention analyzed the vibration mechanism of this type of gapped iron-core reactor, and as a result of various considerations, gap spacers with a large Young's modulus were installed in the center part of the leg core, and gap spacers were installed in the upper and lower ends. The noise caused by the magnetic attraction force is reduced by arranging gap spacers each having a small Young's modulus.

とともに強固に締付けられる。 An embodiment of the present invention will be described below with reference to FIG. Note that parts given the same reference numerals as in FIG. 1 indicate the same or corresponding parts. Reference numeral 21 denotes a gap spacer made of porcelain such as ceramic, thermosetting synthetic resin, silicon glass laminate, etc., which has a large Young's modulus, and is interposed between the block cores 1 and 1 in the center portion of the leg core 3; 22 is a leg spacer. A material such as anti-vibration rubber, press board, Bakelite, A gap spacer made of insulating paper, thermoplastic synthetic resin, etc. Here, it goes without saying that the gap spacers 22 may be arranged in two or three stages at both the upper and lower ends, if necessary. Reference numeral 23 denotes an insulator made of a pressboard plate, a paper frame, etc., which is inserted between the leg core 3 and the yoke 4 so as not to form a short circuit. A desired magnetic gap is constructed by the gap formed by these gap spacers 21, 22 and the insulator 23, and the leg core 3 or yoke 4 is
It can be firmly tightened together.

づく騒音が抑制される。 With the above configuration, the vibration and amplitude due to the magnetic attraction force in the central part of the leg core 3 are suppressed because the Young's modulus of the gap spacer 21 interposed in this part is large, and Since the gap spacer 22 at the end has a small Young's modulus, vibration transmission to the yoke 4 is further suppressed, and as a result, vibration of the entire core can be suppressed, and noise based on this can be suppressed.
以上の通り、この発明によれば、きわめて簡単

できる効果を奏する。 As described above, according to the present invention, even with an extremely simple configuration, it is possible to reduce the noise caused by the magnetic attraction force of this type of gapped iron core reactor.
