Description
Предлагаетс зстрокство дл определени угла сдвига между э. д. с. си1;хро н-юй машины и напр жением на зажимах последней с использованием всиомогательпой синхронной машииь, механически св занной с испытуемой машиной, и приключенного к зтпм i.fautHHBM ваттметра, показывающего непосредстзенио измер емый угол.A line is proposed to determine the angle of shift between e. d. Si1; hro ny machine and the voltage at the terminals of the latter using a synchronous machine, mechanically connected with the machine under test, and the wattmeter that is traced to the i.fautHHBM, showing the measured angle directly.
Схема предлагаемого устройства изображена па чертеже.The scheme of the proposed device is shown pa drawing.
Ротор вспомогательпсто синхрон-мого генератора 1 механически соединен с ротором иснытуемой машины , а напр жение вспомогательного генератора св зано с э. д. с. испытуемого генератора (машины).The rotor of the auxiliary synchronous generator 1 is mechanically connected to the rotor of the machine under study, and the voltage of the auxiliary generator is connected with e. d. test generator (machine).
При нагрузке основного генератора напр жение на его зажимах отстает от э. д. с. ка некоторый угол, который измер етс нулевым ваттметром-фазометром 2, включенным по спецкалы-ой схеме.When the main generator is loaded, the voltage at its terminals lags behind e. d. a certain angle, which is measured by a zero wattmeter-phase meter 2, connected according to a special scheme.
Обмотка возбуждени ваттметра 2 включенЕ 3 гсол:етппческую разность напр жений испытуемого и всгюмогатг.ль:1ого генор торов.The excitation winding of the power meter 2 is turned on for 3 Gsol: the difference between the voltages of the test person and the total voltage of the first genitor.
Токова обмотка саттметра 2 подключена к напр жению основного генератора через и дл ктивное сопротивление Z, о5еспечива1нлцее сдвиг фазы тока в этой цепи на угол отношению к прнложенному напр жению .The current winding of the sattmeter 2 is connected to the voltage of the main generator through and for the resistance Z, allowing for the phase shift of the current in this circuit by an angle relative to the applied voltage.
Шкала ваттметра 1радуируетс в значени х измер емого угла сдвига фаз.The wattmeter scale is measured in terms of the measured phase angle.
