Description

Насто щее изобретение относитс  к устройствам дл  автоматического управлени  пуском однофазного Конденсаторного двигател  в функции скорости с использованием двухобмоточното электромагнитного реле со встречно действующими обмотками тока и напр жени , осуществл ющего подключение дополнительного конденсатора параллельно основному конденсатору при пуске и перегрузках.The present invention relates to devices for automatically controlling the start-up of a single-phase capacitor motor as a function of speed using a double-winding electromagnetic relay with counter-acting current and voltage windings connecting the additional capacitor in parallel with the main capacitor during start-up and overloads.

В известных устройствах подобного рода одна из обмоток реле включена на напр жение вспомогательной (или индуктивной в случае соединени  обмоток треугольником) фазы двигател .In known devices of this kind, one of the windings of the relay is connected to the auxiliary voltage (or inductive in the case of a delta winding connection) of the motor phase.

Предлагаемое устройство отличаетс  от известных тем, что друга  обмотка реле включена в неразветвленную часть цепи конденсаторов, причем в цепь дополнительного конденсатора введен нормально замкнутый контакт реле.The proposed device differs from the known ones in that the other relay coil is included in the unbranched part of the capacitor circuit, and a normally closed relay contact is inserted in the additional capacitor circuit.

Такое выполнение устройства позвол ет повысить надежность его работы и упростить настройку реле.Such an embodiment of the device makes it possible to increase the reliability of its operation and simplify the configuration of the relay.

На фиг. 1 и 2 изображены схемы предлагаемого устройства в двух вариантах исполнени .FIG. 1 and 2 are diagrams of the device in two versions.

Однофазный конденсаторный двигатель может иметь две обмотки статора и и (фиг. 1) или три обмотки А, В и С, соединенные по различным схемам (фиг. 2).A single-phase capacitor motor can have two stator windings and and (Fig. 1) or three windings A, B and C, connected according to different schemes (Fig. 2).

Дл  подключени  пускового конденсатора С„ при пуске и перегрузках двигател  параллельно рабочему конденсатору Ср используетс  электромагнитное дифференциальное реле с нормально закрытыми главными контактами ДР. Токова  обмотка ДР дифференциального реле включена в неразветвленную часть цепи конденсаторов, а обмотка напр жени  ДР --параллельно обмотке двигател , последовательно которой включены конденсаторы (ф г. 1), или же параллельно обмотке двигател , шунтированной катзшкой индуктивности L (фиг. 2).In order to connect the start capacitor C "during start-up and engine overloads parallel to the working capacitor Cp, an electromagnetic differential relay with normally closed main contacts DR is used. The current winding DR of the differential relay is included in the unbranched part of the capacitor circuit, and the voltage winding DR is parallel to the motor winding, in series with which capacitors are connected (г. g 1), or parallel to the motor winding shunted by inductance L (Fig. 2).
