Description

Известно устройство дл  управлени  двухобмоточным электродвигателем посто нного тока последовательного возбуждени , содержащее мосты на тиристорах и обратных диодах , в общую диагональ которых включена обмотка  кор , причем между каждой парой общих точек мостов включены обмотки возбуждени , кажда  из которых шунтирована диодом , а также общий узел искусственной коммутации , состо щий из конденсатора, трансформатора , дроссел  и двух вспомогательных тиристоров.A device for controlling a two-winding direct-current motor of sequential excitation is known, which contains bridges on thyristors and reverse diodes, in the common diagonal of which a core winding is connected, and each excitation winding, each of which is shunted by a diode, as well as a common node are connected between each pair of common points of bridges switching, consisting of a capacitor, a transformer, drossel and two auxiliary thyristors.

Дл  уменьшени  веса и габаритов трансформатора и дроссел  гас щего устройства в предлагаемом устройстве обмотка дроссел  включена .между одной обмоткой возбуждени  и диодом, а между другими обмоткой возбуждени  и диодом включена вторична  обмотка трансформатора.In order to reduce the weight and dimensions of the transformer and the throttles of the damping device in the proposed device, the throttle winding is turned on between one excitation winding and the diode, and between the other excitation winding and the diode the secondary winding of the transformer is turned on.

Благодар  этому в рабочем интервале ток «агрузки не протекает через обмотки дроссел  и трансформатора узла искусственной коммутации и, следовательно, не вызывает их подмагничивани .Due to this, in the working interval, the “load” current does not flow through the windings of the throttles and the transformer of the artificial switching unit and, therefore, does not cause their magnetisation.

На чертеже дана схема описываемого устройства .The drawing is a diagram of the described device.

Устройство содержит мосты еа тиристорах 1-4 и обратных диодах 5-8, в общую диагональ которых включена обмотка  кор  9. Между общими анодами тиристоров 1 и 2 и The device contains bridges in thyristors 1–4 and inverse diodes 5–8, in the total diagonal of which the winding of the core 9 is included. Between the common anodes of thyristors 1 and 2 and

катодами диодов 5 и 6 включена обмотка 10 возбуждени , а между общими катодами тиристоров 4 и 3 и анодами диодов 7 и 8 - обмотка 11 возбуждени . К общим анодам и катодам диодов 5, 6 и 7, 8 подключе источник 12 питани .

Последовательно соединенные первична  обмотка 14 и вспомогательный тиристор 17 подключены к зажимам конденсатора 13. Вторична  обмотка 15 трансформатора через диод 20 включена параллельно обмотке 10 возбуждени , а обмотка дроссел  16 через диод 21 - параллельно обмотке 11 возбуждени .The excitation winding 10 is connected to the cathodes of diodes 5 and 6, and the excitation winding 11 between the common cathodes of thyristors 4 and 3 and the anodes of diodes 7 and 8. To the common anodes and cathodes of diodes 5, 6 and 7, 8 connect the power supply 12. The common commutation node consists of a capacitor 13, a transformer with a primary 14 and a secondary 15 windings, throttles 16 and auxiliary thyristors 17 and 18. Consistently connected capacitor 13, thyristor 18 and choke 16 are connected to an additional power source 19. The primary winding 14 and the auxiliary thyristor 17 are connected in series to the terminals of the capacitor 13. The secondary winding 15 of the transformer through the diode 20 is connected in parallel to the excitation winding 10, and the winding of the electrodes 16 through the diode 21 to parallel to the excitation winding 11.

Предположим, что после отпирани  вспомогательного тиристора 18 конденсатор 13 зар жаетс  через обмотку дроссел  16 от дополнительного источника 19 питани . В рабочем интервале включены тиристоры 1 и 3. При этом ток нагрузки протекает по цепи: источник 12- обмотка 10 - тиристор 1 - обмотка  кор  9 - тиристор 3 - обмотка 11 - источник 12. После отпирани  вспомогательного тиристора 17 конденсатор 13 перезар жаетс  ио цепи:Suppose that after unlocking the auxiliary thyristor 18, the capacitor 13 is charged through the winding of the throttle 16 from the additional source 19 of the power supply. In the working interval, the thyristors 1 and 3 are turned on. In this case, the load current flows through the circuit: source 12- winding 10 - thyristor 1 - winding of the core 9 - thyristor 3 - winding 11 - source 12. After unlocking the auxiliary thyristor 17, the capacitor 13 is recharged :
