Abstract
Abstract The present invention relates to a device for voltage regulation of electrical installations and operating modes of the induction motor, comprising transformers, complete measuring equipment, protective and switching equipment, with the primary winding of transformers being connected in series in each phase of the load and the secondary winding of transformers being either disconnected from the network and connected to each other, or integrated between zero-phase networks and arranged in series with limiting resistors being shunted with a time delay during the switching, which device is characterized in that the regulation is performed as a function of rated voltage and the resistive load as a function of the rated motor current regulating transformers due to electromotive force induced in the secondary winding of the transformer.

A device for voltage optimization and optimization of energy consumption
Description
The present invention relates to a device for voltage regulation in LV networks. The device serves for voltage optimization, energy consumption optimization, the protection of electrical equipment at change of voltage - be it a decrease or an increase in excess of the standards, for reducing reactive power, for reducing current of the load, for harmonic filtering. The invention relates to the field of electrical engineering and can be used to power electrical equipment, lighting networks, communication systems, automation and remote control of residential and public buildings in order to optimize the operation of electrical equipment and energy saving.
Device has two options:
1) device comprising an adjusting transformer with primary winding is connected in series to the load phase and the secondary winding is connected permanently between the phase and zero network with different polarity
2) or secondary winding is connected to automatic control system, includes voltage relay controller network and switching equipment, with primary winding transformer is connected in series to the load phase, and the secondary winding of transformer is disconnected from the network, and shorted or connected between the phase and zero network with different polarity and in series with a limiting resistor, which is short-circuited during the commutation.
This causes the primary winding voltage change at the point output primary winding with respect to point input primary winding, due to the induced electromotive force of the secondary winding. This makes it possible to optimize the diet as a load, taking as a reference point an acceptable level of supply voltage electro consumer to reduce it to the
2019100540 20 May 2019 level to optimally acceptable and, therefore, the minimum consumption of the energy of the network.
Presented in the enclosed drawing, in which Fig. 1 is a schematic diagram of the device according to the present invention for one phase. In the drawing Fig. 1, the symbols used have the following meaning: QF, QF2, QF3 denote circuit breakers input and bypass, QS1 denotes circuit breakers control unit, C is a shunt capacitor, KI and K2 are contactors control, K3 is a shunt contactor, LC denotes a logic controller, CT is a current transformer, R is a ballast resistor and U destinations mode. Other symbols and elements present in the diagram have their standard meanings.
The above-described embodiments of the present device are simple, convenient and highly effective means of optimization of energy consumption.
Adjustment is carried out as a function of the input supply voltage and as a function of the rated current.
The now proposed invention model is suitable for application to any load including motors 0,4 kV network: most electrical equipment lamps, air conditioners, heating equipment, pumps, compressors, fans and the like.
