Abstract

PURPOSE:To prevent generation of offensive odor of varnish and to reduce a vibration noise by hard varnish and further to perform impregnation of varnish in a short time by inserting varnish dropping nozzles in lead-out holes for performing the inpregnation of the varnish. CONSTITUTION:A transformer coil as an object to be processed is contained in a cover 3 composed of a coil container 1 and a core container 2. A lead-out holes 5 for leading out leads 4 connected to a coil part to the outside are opened on the coil container 1. This lead-out holes 5 have enough spaces for insertion of the front ends of varnish dripping nozzles 6. Also the cover 3 eliminates the part for a lead-out hole and is enclosed tightly. Next, the front end of the varnish dripping nozzle 6 is inserted in the lead-out hole 5 to perform dripping and impregnation of the varnish. Consequently, bent of the leads 4 and generation of offensive odor of the varnish are prevented and vibration noise is reduced by hard varnish and impregnation of the varnish can be performed in a short time.

を施せない問題があった。Conventionally, transformer coils have been impregnated with varnish to fix the coil portion and core, reduce vibration noise, and further prevent rust. Therefore, the varnish impregnation treatment involves housing the transformer coil inside the cover and immersing it in a varnish bath.
This is done by allowing the varnish to seep into the interior through the gaps in the cover. Further, a lead wire connected to the coil portion is led out from the side portion of the cover. For this reason, a highly flexible varnish is usually used to prevent the lead wires from being bent by the varnish that hardens after varnish treatment. However, there was a problem in that in order to sufficiently reduce vibration noise, a hard varnish had to be used. Furthermore, since the varnish treatment is performed by immersing the transformer coil in the varnish bath, there is a problem that a bad odor is emitted from the varnish bath. Furthermore, in the case of dip impregnation, a large amount of varnish is put into the varnish bath and used by recycling, so it is necessary to use a varnish that is stable for a long period of time. There was a problem that it was not possible to perform varnish impregnation treatment in a short amount of time.

The present invention provides a method for varnishing a transformer with a cover, which can be applied with varnish.

以下、本発明の実施例について図面を参照してＮ９明す

にする。As shown in FIGS. 1 and 2, a transformer coil, which is an object to be processed, is housed in a cover 3 consisting of a coil housing section 1 and a core housing section 2. As shown in FIGS. The coil accommodating part 1 is provided with a lead-out hole 5 for leading the lead wire 4 connected to the coil part to the outside. This outlet hole 5 is connected to a varnish dripping nozzle 6.
There shall be sufficient clearance to insert the tip of the Further, the cover 3 is kept in a sealed state except for this outlet hole 50 portion.

る。According to this method of varnishing a transformer with a cover, no varnish adheres to the lead wires 4, so
A hard varnish can be used to sufficiently reduce vibration noise. Moreover, since a hard and fast-curing varnish can be used, the varnish impregnation treatment time can be shortened. Furthermore, since the varnish dripping nozzle 6 is used for drip impregnation, it is possible to suppress the bad odor of the varnish from dispersing into the surroundings.
