AT526386A1 - Fused and optionally balancing socket/feed socket combination for installation in a flush-mounted box - Google Patents

Abstract

Socket/feed socket combination for use in a flush-mounted installation box (4). This includes at least one socket (2) made of CEE 7/4, CEE 7/7, EN50075, or combined sockets and a standard-compliant feed socket (7) currently in accordance with DIN VDE V 0628-1 for Germany. The sockets (2) are protected against excessive currents by a fuse and the measurement of the currents allows the display (3) of the balance between demand and feed-in, and when connected to the smart meter also the entire balance on the phase in question.

Description

The invention relates to a fused and optionally balancing socket/feed socket combination

for installation in a flush-mounted box.

The need to use special sockets to feed in PV electricity from balcony power plants creates a problem for apartments if no additional socket can be installed. The present invention is dedicated to this task

with a practical approach.

The technical task of the invention is to enable a safe, standard-compliant feed into a balcony power plant by using an existing socket, and at the same time to keep a CEE 7/3 Schuko or CEE 7/7 socket available. In addition, the socket replacement should also show the balance between feed-in and consumption at this socket so that your own consumption can be maximized. Optionally, the current balance can also be displayed on the smart meter if it is connected via a local network. Switching between these two modes is optionally possible. Through the connected

CEE 7/4 or 7/7 socket could have a higher current in the line to the connected consumption, so this is directly in the double socket

separately insured.

The invention is illustrated using an exemplary embodiment

explained in more detail according to the drawings, whereby Fig. 1

an exemplary variant with LED scales and CEE 7/4 socket (type F), Fig. 2 shows a variant with LCD/OLED display and CEE 7/7 socket, variants with the obsolete type E without notches for grounding are also conceivable . Fig. 3 shows a variant with three connected Euro plug EN 50075 sockets which can advantageously be controlled separately for load shedding. In addition, combinations of socket types and possibly also single-phase CEE/Mennekes sockets are possible. Even if it is conceivable to connect two phases with two power sockets, this is safety-related (two separate supply lines are required) and takes up installation space

difficult to imagine.

Fig. 4 shows an exemplary system architecture with optional connection to the smart meter. Fig. 5 shows the system architecture for a model predictive control. The user interface can e.g. can be used to connect (constant) consumers. User input can be done locally via buttons, a touch-sensitive display, or via a

connected nomadic device.

Fig. 6 shows the protection so that the sum of the fed-in current and the protected current does not increase beyond the permissible level. A slow-acting fuse is sufficient for this, which is the usual one

covers. This means that DGS 0001:2019-10 or DIN VDE V 0628-1 can be met.

With a replaceable fuse, the value of the fuse can be recorded automatically using an RFID tag, mini switches set using a key principle or measuring the voltage drop

about the backup.

Networking creates new possibilities such as electronic control of consumers. Certain functions require changes to the smart meter, e.g. if the socket unit wants to know the consumption on the relevant phase. This can be accomplished via PLC. Load control of devices that are connected to any sockets in the circuit can also be done via PLC. Two or more units can be used not only if there are different phases in the house. For the same phase, the maximum feed line must be reduced. A connection to a cloud-based data aggregator or a mobile phone allows the various units to be evaluated. If a socket is switched off due to a lack of power, a period of time should be adjustable until it can be switched on again so as not to endanger the device (e.g. in refrigerators). This can be done either via an app or via one or more inductive or push buttons on the

device.

Claims (9)

Patent claims 1. Socket-feed socket combination, characterized in that the CEE 7/4 or CEE 7/7 socket is retained in a flush-mounted installation box. 2. Socket-feed socket combination, according to claim 1, characterized in that the current strength in the CEE 7/4 or CEE 7/7 socket is limited. 3. Socket-feed socket combination, according to claim 1 or 2, characterized in that the current balance between consumers at the CEE 7/4 or CEE 7/7 socket and feed through the PV Socket is displayed or signaled. 4, socket-feed socket combination, according to one of claims 1 to 3, characterized in that the current balance is measured on the smart meter is displayed or signaled. 5. Socket-power socket combination, according to one of claims 1 to 4, characterized in that the scale of the pearl chain is based on the LCD protection is displayed 6. Method for operating a socket/feed socket combination, according to one of claims 1 to 5, characterized in that the Current balance from current measurement of 5/21 G. Cebrat ice-feeding socket and the sum of the consumer sockets are determined and other consumers are switched in a process from a connected distributor with switching actuators, Bluetooth, ZigBee, WLAN, PLC... 7. Method for operating a socket-feed socket combination, according to claim 6, characterized in that signals from electricity price, CO2 intensity, or network load are used to charge consumers with storage capacity such as hot water tanks, refrigerators, etc. when there is a surplus and the feed-in tariff is low. This can also be done in such a way that the number of hours that charging must take place and the yield factor can be estimated using historical data and using forecast data for solar radiation and, if variable, the feed-in tariff can be determined in which hours of the forecast horizon charging should take place. The number of charging hours can be increased via the user input on the device presented or via a nomadic unit if the automatic adjustment to a target (temperature to a certain time) is not enough. 8. A method for operating a socket feed socket combination, according to claim 6 or 7, characterized in that if several sockets are controlled, the loads are measured and that socket is switched off so that the others are connected feed-in power results. 6/21 G. Cebrat 9. Method for operating a socket feed socket combination, according to claim 6, 7 or 8, characterized in that the devices are only switched on again after a definable period of time become. 7/21 G.
