本発明は、開放形電動機など使用中にコイルの表面にじ
んあいなどが付着し易い電気機器のコイルに対する絶縁
処理方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for insulating a coil of an electrical device such as an open type electric motor, in which dust and the like tend to adhere to the surface of the coil during use.
汎用誘導電動機などの電気機器においては、そのコイル
の絶縁処理として一般にフェノの含浸による方法が採用
されており、その−例を第１図によって説明すると、１

０は電磁弁であり、予熱した固定子コイル１を回転させ
ながラワニスタンク２の中に貯えてあろ含浸性に優れた
フェノを電磁弁６〜１０を開くことにより各滴下パイプ
３，４．５に圧送し、これによりフェノを固定子コイル
１０表面に滴下させろ。In general-purpose induction motors and other electrical equipment, the method of insulating the coils by impregnating them with phenol is generally used.
1 is an electrical equipment coil to be insulated, for example, a stator coil that has been installed on the stator core of a general-purpose induction motor, 2 is a varnish tank, 3, 4, 5 are varnish dripping pipes, 6 to 1
0 is a solenoid valve, and while the preheated stator coil 1 is being rotated, the phenol, which has excellent impregnating properties, is stored in the lawanis tank 2 and the dripping pipes 3, 4. , and thereby cause the pheno to drop onto the surface of the stator coil 10.
このとき、固定子コイル１を回転させている回転軸を傾
けておき、その回転と共にフェノが固定子コイル１の表
面全体にまんべんなく滴下され、コイルの内部にまで充
分に含浸されるようにする。At this time, the rotation axis on which the stator coil 1 is rotated is tilted so that the phenol is evenly dropped over the entire surface of the stator coil 1 as it rotates, and is sufficiently impregnated into the inside of the coil.
その後、電磁弁６〜１０を閉じ、固定子コイル１を回転
させている回転軸を水平に移し、回転を継続させ、コイ

ル化とそれに続く硬化を行なわせて絶縁処理を終了させ
る。従って、この絶線処理工程を示すと第２図のように
なる。Thereafter, the electromagnetic valves 6 to 10 are closed, and the rotation axis that rotates the stator coil 1 is moved horizontally, and the rotation is continued to allow the gelation and subsequent hardening of the pheno while preventing the pheno from being washed away from the coil 1. This completes the insulation process. Therefore, this disconnection treatment process is shown in FIG. 2.
このときに使用する滴下含浸用のワニスとしては、優れ

剤系のイソフタル酸不飽和ポリエステルワニス、酸無水
硬化形又は変性アミン硬化形のエポキシワニスなどが主
に用いられている。The varnish used for drip impregnation at this time is a solvent-free isophthalic acid unsaturated polyester varnish, an acid anhydride curing type or a modified amine curing type epoxy, from the viewpoint of requiring excellent impregnating properties and short curing properties. Varnishes are mainly used.
しかしながら、これらのワニスは高温での粘性低下が著
しく、そのため含浸性には優れているもののコイル表面
への付着量が充分に得られないという問題点がある。However, these varnishes have a significant drop in viscosity at high temperatures, and therefore, although they have excellent impregnating properties, they have the problem that a sufficient amount of adhesion to the coil surface cannot be obtained.
一方、このような汎用誘導電動機などにおいては、はと

などの多い環境下で使用された場合にはコイルの表面に
じんあいなどが付着し易くそのためコイル電線の絶縁被
膜に欠陥などがあったときには絶縁低下をひき起こし易
い。On the other hand, most of these general-purpose induction motors have an open self-ventilation cooling system, and if they are used in a dusty environment, dust may accumulate on the surface of the coil. Therefore, if there is a defect in the insulating coating of the coiled wire, the insulation is likely to deteriorate.
そこで、このようなワニスの滴下含浸絶縁処理による電
気機器においては１．、、、−下に示すような方法を適
用することによりコイル表面の絶縁強化を図っていた。Therefore, in electrical equipment using such varnish drop impregnation insulation treatment, 1. , , - The insulation of the coil surface was strengthened by applying the method shown below.
１、滴下含浸処理後、溶剤系ワニスの浸漬処理を追加す
るとともに、ベニガラ等を混入した仕上ワニスの浸漬あ
るいは吹付を追加し、コイル表面のワニス付着を厚くす
る。1. After the drip impregnation treatment, add a dipping treatment with a solvent-based varnish and add dipping or spraying with a finishing varnish mixed with red rosewood etc. to thicken the varnish adhesion on the coil surface.
２、滴下含浸処理後、マイカ粉等を多量に混入したコン
パウンド状ワニスをコテ塗りする。2. After the drip impregnation treatment, apply a compound varnish containing a large amount of mica powder etc. with a trowel.
３、滴下含浸処理後、ポリアミドのウィック材、エロジ
ール等の混入により揺変性化したワニスに浸漬する。3. After the dropwise impregnation treatment, it is immersed in a varnish that has been made thixotropic by mixing a polyamide wick material, Erosil, etc.
４、 コイル表面にガラステープ等の繊維テープを巻い
て滴下ワニスと含浸ワニスの流出を防止するとともにテ
ープのワニス含浸によって補強する。4. Wrap a fiber tape such as glass tape around the coil surface to prevent dripping varnish and impregnated varnish from flowing out, and reinforce it by impregnating the tape with varnish.
しかしながら、これらの方法にはそれぞれ次のような問

作業工数の増加が著しい。３の方法では、揺変化
Ｉｔ。However, each of these methods has the following problems. That is, in method 1, the processing time, especially the drying time, increases significantly due to the increase in the number of dippings of the solvent-based varnish, and the work requires a long time. In method 2, skill is required for the troweling work, and 1.: The number of man-hours increases significantly. In method 3, the oscillatory change

業工数の増加が著しい。This oscillating varnish requires a large amount of varnish, and the usable life of the varnish, that is, the time until it hardens and becomes unusable, is short, resulting in a large loss of varnish. In method 4, it is difficult to completely cover the entire surface of the coil with tape, and the work requires skill, resulting in a significant increase in the number of work steps.

１の温度を上昇させてＡワニス、Ｂワニスを完了する。Then, the solenoid valves 6 to 10 are opened, and the A varnish in the varnish tank 6 is pumped by a pump or pneumatic VC (not shown), passes through the solenoid valves 8 to 10, reaches the drip pipes 3 to 4, and reaches the surface of the coil 1. It is dripped into the liquid and is evenly impregnated into it. After all of the A varnish in the varnish tank 2 has been dripped and impregnated onto the carp A/1, the solenoid valves 6 and 7 are closed.
Carp A/1 ft Move to horizontal rotation. And coil lK
When the impregnated varnish A is gelled, the solenoid valves 13 to 15 are opened, and the varnish B in the varnish tank 11 is passed through the opened solenoid valves 8 to 10, 15 to the drip pipes 3 to 4. 12 and dripped evenly onto the surface of the coil 1. At this time, since B varnish has a high viscosity due to popularization as described later, Koi/I
The coil 1 does not penetrate into the coil 1, flow significantly on the surface, or drip from the coil 1, and is maintained evenly on the surface of the coil 1 with a sufficient thickness. In this way, when the dropping of the B varnish in the varnish tank 11 is finished, the electromagnetic valves 9 to 14 are closed, and after the B varnish has gelled, the temperature of the coil 1 is raised to complete the A varnish and B varnish.
以上を工程図で示すと第４図のよ５になる。If the above is shown in a process diagram, it becomes 5 as shown in FIG.

長くなることもない。Therefore, according to this embodiment, since the hardened varnish layer is formed with a sufficient thickness on the surface of the stator coil 10, there is no risk of insulation deterioration due to adhesion of dust, etc. Moreover, since the process is performed simply by dropping the varnish and then curing it, the process is simple and easy, and the working time does not take long.
次に、Ｂワニスの実施例を次に示す。Next, examples of B varnish are shown below.
実施例 ■

つＡワニスとの一体硬化性が充分なものとした。Example ■ An acid anhydride curing type epoxy varnish was used as the A varnish for impregnation, and quartz powder 20 to 40 weight Is and a thixotropic agent, also known as Erosil, were mixed into this varnish to make it highly concentrated. Varnish B was made to have a thixotropic viscosity, thereby reducing the fluidity after dropwise application to the coil and providing sufficient curing properties together with Varnish A.

性カ（充分なものとした。Example ■ When unsaturated epoxy ester fest was used as A varnish for impregnation, 20 to 40 parts by weight of quartz powder and an appropriate amount of a thixotropic agent (Erosil) were mixed into this varnish to make it thixotropic with high viscosity. Varnish B was used to reduce the fluidity after dropwise application to the coil, and to ensure sufficient curing ability together with Varnish A.

特性を大きく改善することができる。As in these examples, when varnish A is mixed with quartz powder and a thixotropic agent to make varnish B, the fluidity after coating on Woma and Koi/l/ is sufficiently suppressed, making it difficult to apply the varnish layer. Even if the thickness is increased, it is easy to reduce losses due to varnish flowing out, and the occurrence of cracks due to increased coating thickness is greatly improved compared to when only varnish is used.For example,
The temperature at which cracks occur when applying a varnish containing quartz powder is 10° to 20° lower than the temperature at which cracks occur when a thick varnish is applied, making it possible to significantly improve crack resistance. .

It is sprayed onto the surface of the coil to make it adhere to the A varnish impregnated in Koi/I/1, and then the temperature is raised to bond and harden them, forming an insulation reinforcing layer on the coil surface.
