本発明は回転電気機械の回転子に係り、特に、タービン
発電機に使用される回転子の構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotor for a rotating electrical machine, and more particularly to the structure of a rotor used in a turbine generator.
固定子枠内に交流発電機、交流励磁機及び回転整流器を

つた。In a rotating electric machine equipped with an alternating current generator, an alternating current exciter, and a rotating rectifier in the stator frame, the conventional method is to measure the insulation resistance of the field coil by removing the manhole cover etc. installed on the stator and measuring the insulation resistance of the field coil. Previously, measurements were taken by inserting measurement terminals from the rotor to the exposed part of the rotor's conductive parts.
With this method, the manhole cover had to be removed every time measurements were taken, and the exposed part was inside, making it difficult to work.
又、固定子が内圧防爆構造でマンホールカバー等を開け
た場合には、内部掃気を必要とする発電所、あるいは、
起動停止のたび毎に絶縁抵抗を測定する発電所では、き
わめて不便であった。In addition, if the stator has an internal pressure explosion-proof structure and a manhole cover is opened, power plants that require internal scavenging or
This was extremely inconvenient for power plants where insulation resistance was measured every time the power plant started or stopped.
本発明の目的は、界磁コイルの絶縁抵抗測定が簡単に出
来る回転電機の回転子構造を提供するにある。An object of the present invention is to provide a rotor structure for a rotating electrical machine that allows easy measurement of insulation resistance of a field coil.
本発明の要点は、固定子枠内に交流発電機・交流励磁機
及び回転整流器を備えている回転電気機械の回転子にお
いて、界磁コイルよりの一端子を中心孔を通して、軸受
部の外側に引き出す構造とした回転子の絶縁抵抗を容易
に測定出来る構造にある。The gist of the present invention is that in a rotor of a rotating electric machine that is equipped with an alternating current generator, an alternating current exciter, and a rotary rectifier in a stator frame, one terminal from a field coil is passed through a center hole and is connected to the outside of a bearing part. It has a structure that allows easy measurement of the insulation resistance of the rotor, which has a pull-out structure.
本発明の一実施例を第1図および第2図に示す。An embodiment of the invention is shown in FIGS. 1 and 2.
固定子枠1内に交流発電機回転子部3と交流励磁機回転
子部4、回転整流器部5を設け、さらに、両端に°Cン

ード線より絶縁抵抗測定用リード9を取り出し、それを
中心孔を通して軸端まで引き出す構造として、回転子リ
ードの絶縁抵抗を容易に副手出来るようにした。In a rotor of a rotating electric machine, an alternating current generator rotor part 3, an AC exciter rotor part 4, and a rotating rectifier part 5 are provided in a stator frame 1, and further has a °C bracket 7 and a bearing 8 at both ends. The insulation resistance measuring lead 9 is taken out from the lead wire leading to the alternator field coil, and is pulled out through the center hole to the end of the shaft, so that the insulation resistance of the rotor lead can be easily measured.
力お、図中2はシャフト、6はラジアルファン10はカ
バー、11はスペーサーである。In the figure, 2 is a shaft, 6 is a cover for the radial fan 10, and 11 is a spacer.
本発明によ詐ば、回転子リードの絶縁抵抗測定が、固定
子枠に設けたマンホールカバー等ヲ外さないで出来る。According to the present invention, the insulation resistance of the rotor lead can be measured without removing the manhole cover etc. provided on the stator frame.
又、内圧防爆形タイプでマンホールカバー等を開けた場
合には、必ず、内部掃気を行なって、固定子枠内のガス
をきれいにしている発電所などの場合には、従来は絶縁
抵抗測定のたび毎に、内部掃気が必要であったが、本発
明の方式を採用することにより、そnらが不要となる。In addition, in the case of power plants, etc., where whenever a manhole cover, etc. of an internal pressure explosion-proof type is opened, internal air scavenging is performed to clean the gas inside the stator frame. Internal scavenging was necessary every time, but by adopting the method of the present invention, this becomes unnecessary.
さらに、発電所によっては起動停止のたびに絶縁抵抗を
測定している所がおるが、今後は起動停止のたびにマン
ホールカバー等を開けて、作業性の悪い所で絶縁抵抗を
測定する必要がなくなる。Furthermore, some power plants measure insulation resistance every time they start or stop, but from now on, it will be necessary to open manhole covers and measure insulation resistance every time there is a start or stop, and in places where it is difficult to work. It disappears.
