本考案は、固定子巻線の異常温度上昇を検知し作動する安全保護装置を備えた 電動機の固定子に関するものである。 The present invention relates to a stator of a motor equipped with a safety protection device that detects and operates an abnormal temperature rise in a stator winding.
【０００２】[0002]
従来から固定子には、異常時の安全保護のため安全保護装置を取り付ける必要 があり、固定子巻線に安全保護装置を固定用結束バンド等により固定する構造が 多く用いられている。 以下図面を参照しながら、上述した従来の固定子巻線における安全保護装置の 取付構造の一例について説明する。 図３は従来の安全保護装置を備えた電動機の固定子を示すものである。 図３において、５は固定子鉄心、３は固定子巻線、１は安全保護装置、７は結束 バンドであり、固定子巻線３に安全保護装置１を固定している。８はリ−ド線、 ９は絶縁保護チュ−ブであり、固定子巻線３とリ−ド線８及び安全保護装置等の 接続部の絶縁保護をしている。 以上の様な構成において固定子巻線３に異常が発生した時、固定子巻線３に固 定された安全保護装置１が固定子巻線３の温度上昇により作動し、燃焼等の異常 事態を防止する機能を持たしている。 Conventionally, it has been necessary to attach a safety protection device to the stator for safety protection in the event of an abnormality, and a structure in which the safety protection device is fixed to the stator winding with a binding band for fixing is often used. An example of a mounting structure of the above-mentioned conventional safety protection device in the stator winding will be described below with reference to the drawings. FIG. 3 shows a stator of an electric motor provided with a conventional safety protection device. In FIG. 3, 5 is a stator core, 3 is a stator winding, 1 is a safety protection device, and 7 is a binding band, and the safety protection device 1 is fixed to the stator winding 3. Reference numeral 8 is a lead wire, and 9 is an insulation protection tube, which performs insulation protection of the stator winding 3, the lead wire 8 and the connection portion of the safety protection device and the like. When an abnormality occurs in the stator winding 3 in the above configuration, the safety protection device 1 fixed to the stator winding 3 operates due to the temperature rise of the stator winding 3, and an abnormal situation such as combustion occurs. It has a function to prevent.

しかしながら上記の様な構成においては、電動機組立上、固定子巻線３は所定 寸法内におさめる必要があり、安全保護装置１を取り付ける前に固定子巻線３の 取り付け箇所部の巻線高さの整形修正を行わねばならず、又結束バンド７にて安 全保護装置１の固定子巻線への固定には熟練度が必要であり、手作業に頼らざる を得ないため非常に作業性が悪く、そのうえ、結束バンド７のゆるみ等により安 全保護装置１の密着度が低下しやすいという問題点があった。 また、固定子巻線の表面は凹凸があるため隙間ができ、この表面の温度を検知 する安全保護装置が固定子巻線と接触する面積がすくなくなるため、バラツキが 生じて正確な温度検出を行なうことができなかった。 この考案はかかる問題点を解決するためになされたもので、固定子巻線に対し て確実にしかも作業性がよく取り付けることができ、しかも精度良く温度検出で きる安全保護装置を取り付けることができる。 安全保護装置１の取り付け箇所の巻線高さの整形修正により固定子巻線３にレ アショ−ト等が発生したり、又結束バンド７にて安全保護装置１を固定する際、 結束バンド７による局部的な力により、安全保護装置１が誤動作等の品質的問題 を低減できる固定子における安全保護装置の取付構造を提供するものである。 However, in the above-mentioned configuration, the stator winding 3 needs to be kept within a predetermined size in order to assemble the motor, and the winding height of the mounting portion of the stator winding 3 before the safety protection device 1 is mounted. Must be reshaped, and fixing of the safety protection device 1 to the stator winding with the binding band 7 requires a high level of skill and requires manual work. In addition, there is a problem that the adhesion of the safety protection device 1 is likely to be deteriorated due to loosening of the binding band 7 and the like. In addition, since the surface of the stator winding has irregularities, a gap is created, and the area where the safety protection device that detects the temperature of this surface makes contact with the stator winding is small, resulting in variations and accurate temperature detection. I couldn't do it. The present invention has been made to solve such a problem, and a safety protection device that can be attached to the stator winding securely and with good workability and that can detect temperature with high precision can be attached. . When the safety height of the safety protection device 1 is modified by adjusting the winding height, the stator winding 3 may cause a raratio or the like, or when the safety band 1 is fixed by the binding band 7, The present invention provides a mounting structure of a safety protection device in a stator, which can reduce quality problems such as malfunction of the safety protection device 1 due to the local force of.

【０００５】[0005]
本考案は、上記した様に、端子ケ−スに設けた収納部に安全保護装置を収納固 定することにより、従来、固定子巻線へ安全保護装置を固定するために使用して いた結束バンドが不要となり、又従来行っていた固定子巻線を所定寸法内におさ めるための、安全保護装置の取り付け箇所部の固定子巻線高さの整形修正工程が 不要になる等、その製造工程が簡略化される。 また、安全保護装置が収納部に位置決めでき、かつ、この安全保護装置と固定 子巻線間に耐熱性絶縁性を有する熱伝導性の良い樹脂を注ぎ込んで形成される絶 縁層を介して固定子巻線に密着するので、安全保護装置の取り付けが確実で、し かも、組立てがきわめて容易となり作業性がよい。 また、固定子巻線との密着性が良いため温度検出精度が良くなる。 According to the present invention, as described above, by binding and fixing the safety protection device in the storage portion provided in the terminal case, conventionally, the bundling used to fix the safety protection device to the stator winding. There is no need for a band, and there is no need for the process of shaping the stator winding height at the mounting location of the safety protection device to keep the stator winding within the specified dimensions. The manufacturing process is simplified. In addition, the safety protection device can be positioned in the storage part, and it is fixed via an insulating layer formed by pouring a resin with good heat conductivity and heat resistance and insulation between the safety protection device and the stator winding. Since it comes into close contact with the sub-winding, the safety protection device can be attached securely, and assembly is extremely easy and workability is good. Further, since the close contact with the stator winding is good, the temperature detection accuracy is improved.

以下、本考案の構成を図面に示す実施例に基づいて具体的に説明する。 図１、図２は本考案の端子ケ−スの収納部に安全保護装置を収納して固定子鉄心 に取り付けた状態を示す要部側面断面図と要部平面図を示すものである。 次に端子ケ−スにおける安全保護装置の取付構造について説明する。 図１、図２において、１は安全保護装置で、２は固定子巻線３に近接して端子ケ −ス４に設けた安全保護装置１を収納する収納部である。 この端子ケ−ス４は固定子巻線３が巻装された固定子鉄心５の外周部に固定す る。 なお、端子ケ−スの収納部２にて安全保護装置１を収納固定するとともに、こ の収納部は固定子巻線３の温度を直接検知できるように安全保護装置１の感温部 が露出できるように固定子巻線３と近接して対向される箇所は開放状態となって いる。 この開放状態となっている端子ケ−スの収納部２と固定子巻線３との隙間には 、固定子巻線３の温度を安全保護装置の感温部がより感知できるように耐熱性と 絶縁性にすぐれ、熱伝導性の良いシリコン等の樹脂を上方から注ぎ込んで充填し て絶縁層６を形成する。 この絶縁層６によって電気的絶縁を確保し、電気的影響を受けることなく、温 度検出ができ、また、樹脂によって密着されているので温度検出精度を非常に良 くすることができる。 そして、安全保護装置の組付作業は、端子ケ−スに設けられた収納部２に固定 子巻線３と対向する面を開放とし、両側面より安全保護装置１を挟みつけるよう に挿入するのみでよいため簡単でガタツキが生じなく、また、自動化も可能であ る。 よって、安全保護装置の取付状態は図１、図２に示すように、安全保護装置１ の感温部が絶縁層６を間に挟んで固定子巻線３の端面に接触しているので、固定 子巻線３の温度を安定して、確実に検出することができる。 以上の構成によれば、端子ケ−ス４に安全保護装置を収納する収納部２を設け て、安全保護装置１を収納固定するので、安全保護装置固定用の結束バンド等が 不要となり、又固定子巻線３を所定寸法内におさめるための、固定子巻線３の整 形修正工程が不要となる等、製造工程が簡略化される。 Hereinafter, the configuration of the present invention will be specifically described based on the embodiments shown in the drawings. 1 and 2 are a side sectional view and a plan view of a main part showing a state in which a safety protection device is stored in a storage part of a terminal case of the present invention and attached to a stator core. Next, the mounting structure of the safety protection device in the terminal case will be described. In FIGS. 1 and 2, reference numeral 1 denotes a safety protection device, and 2 denotes a housing portion for housing the safety protection device 1 provided in the terminal case 4 in the vicinity of the stator winding 3. The terminal case 4 is fixed to the outer periphery of the stator core 5 around which the stator winding 3 is wound. The safety protection device 1 is housed and fixed in the terminal case storage part 2 and the temperature sensing part of the safety protection device 1 is exposed in this storage part so that the temperature of the stator winding 3 can be directly detected. As much as possible, the portion facing the stator winding 3 in close proximity is open. The gap between the housing 2 of the terminal case and the stator winding 3 in the open state is heat-resistant so that the temperature of the stator winding 3 can be more sensed by the temperature sensing portion of the safety protection device. Then, a resin such as silicon having excellent insulating properties and good thermal conductivity is poured from above and filled to form the insulating layer 6. The insulating layer 6 ensures electrical insulation, temperature can be detected without being electrically affected, and the temperature detection accuracy can be made very good because it is adhered by resin. Then, when assembling the safety protection device, the side facing the stator winding 3 is opened in the housing 2 provided in the terminal case, and the safety protection device 1 is inserted from both sides so as to be sandwiched. Since it is only required, it is easy and free from rattling, and can be automated. Therefore, as shown in FIGS. 1 and 2, when the safety protection device is attached, the temperature sensing portion of the safety protection device 1 is in contact with the end surface of the stator winding 3 with the insulating layer 6 interposed therebetween. The temperature of the stator winding 3 can be stably detected with certainty. According to the above structure, the terminal case 4 is provided with the storage portion 2 for storing the safety protection device, and the safety protection device 1 is stored and fixed. Therefore, a binding band or the like for fixing the safety protection device is unnecessary, and The manufacturing process is simplified, for example, the step of modifying the stator winding 3 to keep the stator winding 3 within a predetermined size is not necessary.

Moreover, the mounting structure of the safety protection device of the overheat prevention device of this invention is such that the storage part is provided integrally with the terminal case, and the safety protection device is fixed in the storage part so that the temperature sensing part of the safety protection device can be secured. By interposing an insulating layer with heat resistance and good heat conductivity between the stator windings, electrical insulation is secured and temperature detection can be performed without being affected by electrical effects. Further, since the stator winding and the temperature sensing portion of the safety protection device are in close contact with each other by the insulating layer, the temperature of the stator winding can be very accurately detected. Furthermore, since the temperature-sensitive part of the safety protection device is fixed by the insulating layer, the mechanical strength is improved, and the safety protection device does not separate from the storage part even with the vibration of the electric motor. As described above, since the conventional manual work is not required, the quality is stable, mechanical assembly is possible, the temperature detection accuracy is excellent, and the electric motor is more effective than the conventional case. Can provide the stator.
