BG1580U1 - A device for direct current electric power supply of premises and buildings - Google Patents

Abstract

A device for direct current electric power supply of dwellings and buildings which provides direct current supply to the electric power consumers by controlling the transformation of energy from sources of renewable energy into direct current and distributes this direct current electric power in such a way that an optimum performance and energy efficiency be achieved. The device under consideration consists of a guiding block (1) to the output of which the energy sources (2) are connected, these sources of electric power being renewable or conventional. The control block (1), through the attached to it modules of guiding, transforming and distributing, runs the process of the transformation of electric power from the sources of energy (2) into direct current voltage which is then suppliedto the electric power consumers (4) and at the same time charges the block for accumulation of electric energy (5). Besides that, through sensors and performing devices, the guiding block controls the energy distribution and in this way realizes an energy efficient supply to the electric energy consumers.

Description

Technical field

The device finds application where it is necessary to supply power to appliances and devices inside or outside premises and buildings. The device's power source can be renewable or non-renewable. The purpose of the room and building supply unit is to supply DC power to the electricity consumers.

BACKGROUND OF THE INVENTION

A device for supplying premises and buildings is known, which, via electrical connection elements, supplies AC power from an AC source to the electricity consumers. Also known are devices which, from an AC source through electrical connection elements and a conversion element, supply DC power individually to each individual electricity consumer. An AC power unit may be included in the AC part of known devices. It is also characteristic that DC consumers must have an individual AC to DC converter.

The first of the existing devices is characterized by the fact that the electricity supplied by it has a voltage value that is dangerous for human health, has electromagnetic radiation, which leads to energy losses, is a source of electromagnetic interference and has a harmful effect on the the human body. In addition, peak voltages and short-term high-voltage pulses are possible, causing damage to most power consumers. The devices of the second type are individual for each consumer and the DC electricity they supply to the electricity consumers cannot be controlled and redistributed between the consumers for the sake of energy efficiency. With known power supplies, the power storage unit is plugged into the AC part and the accumulated energy is DC, resulting in unnecessary energy losses when converted from AC to DC twice and vice versa.

The technical nature of the utility model

The utility of the utility model is to provide DC power to appliances and devices inside or outside rooms and buildings, which is not dangerous for human health, no electromagnetic radiation leading to significant energy losses, no is a source of electromagnetic interference, does not adversely affect the human body and is not a source of peak voltages and short-lived high-voltage pulses that can cause damage to electricity consumers. In addition, the utility model must provide power to all direct current consumers of electricity, the energy supplied to them can be supplied as constant values, and can be redistributed from the control unit depending on external and internal for device factors.

Advantages of the utility model are the possibilities for unified and uninterrupted low-voltage DC power supply to consumers in premises and buildings, including from sources of renewable energy, as well as the use of a power storage unit, which is included in the DC part and respectively by reducing the losses from the conversion of electricity. A description of the attached figure and an embodiment

Attached figure 1 illustrates the technical implementation of the device for DC power supply of premises and buildings.

According to the attached figure 1, the device for supplying premises and buildings consists of a control unit 1 to the input to which electricity sources are connected 2. The control unit 1 controls the process of converting the energy from the sources 2 into DC voltage, as well as the distribution of DC power to the power consumers 4 and to the power storage unit 5. The electrical connections are made by means of electrical connection elements 6. In addition, to control unit 1, sensors 7 are connected to the power consumers 4 and to the power storage unit 5 through which the control unit 1 receives environmental information, the status of the power storage unit 5 and the operation of the power consumers. 4. Also, actuators 8 are connected to the control unit 1, to the power consumers 4 and to the power storage unit 5 through these sensors 7 and actuators 8 controls. The outlet unit 1 manages the distribution of energy in such a way that the optimal mode of operation of the electricity consumers and maximum energy efficiency is achieved.

Application of utility model

The DC power supply for premises and buildings is used to supply DC power to DC consumers by achieving efficient use of AC and DC power sources, including from renewable electricity sources.
