Abstract
1. Установка для сушки изоляции обмотки тяговых электрических машин содержит узел для нагрева воздуха, узел контроля за состоянием изоляции по ее сопротивлению и узел для подачи нагретого воздуха, отличающаяся тем, что узел для нагрева воздуха снабжен трубчатыми электронагревателями, управляемыми программируемым терморегулятором с контуром обратной связи по датчику температуры, подключенным к сети, узел контроля за состоянием изоляции по ее сопротивлению содержит мегаомметр, подключенный измерительными проводами к обмотке тяговой электрической машине с подачей сигнала на терморегулятор для переключение программы и ее шага, узел подачи нагретого воздуха снабжен электродвигателем с вентилятором, который управляется программируемым преобразователем частоты с контуром обратной связи по датчику температуры, гибкой трубой, на конце которой устанавливается насадка с отражателем.2. Установка для сушки изоляции обмотки тяговых электрических машин, отличающаяся тем, что насадка имеет лопасти, расположенные по винтовой линии, обеспечивающие завихрение подаваемого нагретого воздуха в вентиляционные каналы тяговой электрической машины.1. Installation for drying the insulation of the windings of traction electric machines includes a unit for heating air, a unit for monitoring the state of insulation by its resistance and a unit for supplying heated air, characterized in that the unit for heating air is equipped with tubular electric heaters controlled by a programmable temperature regulator with a feedback loop according to the temperature sensor connected to the network, the control unit for the state of insulation by its resistance contains a megohmmeter connected by test leads to the winding of the traction electric to an electric machine with a signal to the temperature controller to switch the program and its step, the heated air supply unit is equipped with an electric motor with a fan, which is controlled by a programmable frequency converter with a feedback loop for the temperature sensor, a flexible pipe, at the end of which a nozzle with a reflector is mounted. 2. Installation for drying the insulation of the winding of traction electric machines, characterized in that the nozzle has blades located along a helical line, providing a swirl of the supplied heated air into the ventilation ducts of the traction electric machine.
