Description

DOUBLE BRANCH CIRCUIT FOR POWER CONTROL}

The present invention, in the electrical installations installed in buildings, etc., double for selective power cut to prevent standby power or deterioration / overheating / failure / short-circuit or the like that can occur or occur by not disconnecting the plug from the outlet when using the electric heater It relates to a branch circuit.

In general, the electrical equipment installed in a building is divided into a power equipment that is a water substation equipment that receives power from a transmission line, a supply equipment that supplies power to a load equipment by branch circuits, and a load equipment that uses electric power such as a lamp / outlet. Can be.

The user places various heating equipment such as office equipment such as computers / copiers / facsimile machines used in the office, air-conditioning equipment such as fans / heaters / air conditioners, and communication equipment such as key phones / hubs / routers in an appropriate place indoors and load equipment. Connect the plug of each heating device to the in outlet.

The heating device connected to the outlet turns on / off the power by interlocking with the power switch attached to the outlet.However, the power cut by the power switch consumes power as long as the plug is connected to the outlet even without using the heating device. .

In other words, even if the heater is not in use, if the plug is connected to an outlet, unnecessary power is consumed to waste energy and generate electromagnetic waves harmful to the human body, and also deteriorate / overheat / failure / It may cause a short circuit, which may cause a safety accident.

In this way, the standby power before using the heating device is called STANDBY POWER. Recently, in order to save energy by saving the standby power, it is recommended to disconnect the plug of the heating device that is not in use from the outlet. Such efforts are actively being made to save standby power, such as active publicity, but plugging and unplugging plugs and plugs are very cumbersome, and such habits are not easily established.

Furthermore, when the standby power is cut off, it must be cut off except for heaters (hereinafter referred to as 'commercial heaters') that must be powered at all times, such as facsimile machines, answering machines, refrigerators, and air pumps installed in aquariums. Except for the plug of the heater, it is not easy to unplug the remaining heaters.

As a conventional technology for power saving of standby power, a technology in which the outlet itself is provided with an ON / OFF switch to connect / disconnect power supplied to each outlet or extension outlet attached to a wall has been proposed. The outlets that are plugged into the heaters must be found and turned off, and each outlet must be turned on again in order to use it again. Therefore, the inconvenience of having to unplug and reconnect each heater is greatly reduced. it's difficult.

In order to solve these problems, the Korean Patent Utility Model No. 20-0392807, which is the following patent document, is an indoor wiring structure provided between a home distribution panel and an outlet for supplying electricity, and occurs when the heating device and the lamp are not used. In order to cut off the standby power, a standby power cut-off switch structure including one switch connected to the distribution board and the other connected to the outlet was proposed.

However, in the case of the preceding patent document, the commercial heating device outlet and the emergency heating device outlet have a predetermined structure at the time of electrical installation, and thus have a fatal disadvantage that the user cannot arbitrarily arrange the heating device.

That is, for example, considering that the refrigerator, which is one of the commercial heating devices in the house, is mainly installed in the kitchen, any one outlet that is located in the kitchen beforehand is used as a dedicated electrical heating outlet for electrical work, and is located in other living rooms or rooms. If the construction is to be cut off the power by the switchgear, when the user arranges the refrigerator, only need to be installed in the kitchen with a commercial electrical outlet only, if you install the refrigerator in the living room or room, the use of the switch is impossible.

In consideration of this, there are many types of commercial heating devices such as not only refrigerators but also telephones with a caller recording function, faxes for document transmission, and air supply pumps installed in aquariums. It is very difficult to arrange and construct a commercial heating device outlet by predicting its position in advance. Therefore, in the case of the patent document, when the outlet for the commercial heating device is exclusively installed, it is impossible to meet the user's requirements. It is not possible to arrange the heating apparatus freely according to taste.

Accordingly, the present invention has been made to solve the problems of the prior art, the main purpose is to add a redundant dual power line branched in parallel from the P power line to each of a plurality of outlets, and select switch to each outlet By providing each outlet is selectively connected to the dual power line or P power line to provide a dual branch circuit for the optional power cut-off that allows the user to select the power supply circuit of each outlet as needed.
