Изобретение относитс к электротехнике и может быть использовано дл питани мощных индукционных установок , осуществл ющих термическую обработку изделий.The invention relates to electrical engineering and can be used to power high-power induction installations that heat-treat products.
Известно устройство питани дл электротермических установок, выпол-иенное на базе индуктивно-емкостного преобразовател источника напр жени в источник тока 1.A power supply device for electrothermal installations is known, made on the basis of an inductive-capacitive voltage source converter into a current source 1.
Индуктивно-емкостной преобразователь обладает симметрирующими свойствами , однако неравномерность загрузки фаз питанадей сети достигает более 20%, что вл етс неприемлемым при питании мощных однофазных нагрузок.Inductive-capacitive converter has balancing properties, however, the uneven loading of the phases of the power supply network reaches more than 20%, which is unacceptable when powering high-power single-phase loads.
Известно также устройство дл питани однофазной активно-индуктивной нагрузки, содержащее индуктивно-емкостный преобразователь источника напр жени в источник тока, соединенный с первичной обмоткой согласующего трансформатора, снабженной блоком переключени отпаек, вход которого соединен с выходом регул тора напр жени , а вторична обмотка трансформатора св зана с выводами дл подключени нагрузки ,2 .A device for supplying a single-phase active-inductive load is also known. With connections for connecting the load, 2.
Цель изобретени - повышение симметрировани загрузки фаз питающей сети и стабилизации мощности нагрузки.The purpose of the invention is to increase the load phase balancing of the supply network and stabilize the load power.
Дл этой цели ко вторичной обмотке трансформатора последовательно с выводами дл подключени нагрузки включен продольный емкостной компенсатор , управл ющий вход которого соединен со стабилизатором коэффициента For this purpose, a longitudinal capacitive compensator is connected to the secondary winding of the transformer in series with the terminals for connecting the load, the control input of which is connected to the coefficient stabilizer
10 мощности на первом уровне, а блок задани регул тора напр жени выполнен с уставкой, составл ющей Уз линейного напр жени сети.10 at the first level, and the voltage regulator setting unit is made with a setpoint constituting the linear voltage node of the network.
На фиг. 1 приведена схема предло15 женного устройства питани ; на фиг.2 векторна диаграмма.FIG. 1 shows a diagram of a proposed power supply device; 2, a vector diagram.
Устройство содержит индуктивно-емкостной преобразователь 1, блок 2 управлени переключением отпаек первич20 ной обмотки 3 согласующего трансформатора 4. Блок 2 соединен через блок сравнени 5 с датчиком напр жени 6 на первичной обмотке 3. Второй вход блока сравнени 5 соединен с выходом The device contains an inductive-capacitive converter 1, the unit 2 controlling the switching of the faults of the primary winding 3 of the matching transformer 4. The unit 2 is connected via a comparison unit 5 with a voltage sensor 6 on the primary winding 3. The second input of the comparison unit 5 is connected to the output
