Description
Насто щее изобретение относитс к способам пр иведеки во вращение вала турбоагрегата, не наход щегос в работе, предусматривающим подъем вала гидравлическим устройством и вращение его с малой скоростью.The present invention relates to methods for drilling the shaft of a turbine unit, which is not in operation, which involves raising the shaft with a hydraulic device and rotating it at low speed.
Предлагаемый способ отличаетс от известных тем, что дл привода вала используют сопр женный с ним генератор, работающий в режиме электродвигател .The proposed method differs from the known ones in that for the drive of the shaft they use a generator connected with it, operating in the electric motor mode.
Такой способ позвол ет отказатьс от применени редукторной системы (черв чных, и зубчатых понизительных передач) дл вращени вала турбоагрегата.This method allows refusing the use of a gear system (worm gear and gear reduction gears) for rotating the shaft of the turbine unit.
По предлагаемому способу дл вращени вала турбоагрегата с малой скоростью используют сопр женный с ним генератор, работающий в режиме электродвигател . Генератор запускают от сети переменного тока, как асинхронный электродвигатель. При этом в цепь ротора включаетс большое сопротивление во избежание пробо его обмотки.According to the proposed method for rotation of the shaft of the turbine unit at low speed, a generator coupled to it operating in the electric motor mode is used. The generator is started from the AC network, as an asynchronous motor. In this case, a large resistance is included in the rotor circuit in order to avoid the breakdown of its winding.
В цел х уменьшени момента трогани вал турбоагрегата приподнимают с помощью гидравлической системь). При этом масло в подшипники подаетс насосом низкого давлени , а затем давление повышаетс с помощью трансформатора давлени масла.In order to reduce the moment of moving, the turbine shaft is raised using the hydraulic system). The oil in the bearings is supplied by a low pressure pump, and then the pressure is increased by means of an oil pressure transformer.
В случае установки нескольких турбогенераторов на электростанции рекомендуетс иметь дл них общие источники питани электроэнергией и общую масл ную систему.In the case of installing several turbo generators at a power plant, it is recommended to have common power supply sources for them and a common oil system.
