Description
The present invention relates to a power-saving intelligent multi-outlet for fire protection, and more particularly, to prevent failure of an electric device by cutting off power supplied to a load electric device in an internal and external high temperature, an overcurrent, a short circuit or an overvoltage state. It also prevents fires caused by electric accidents and electric accidents, cuts off standby current, reduces power loss, and visually displays the current value flowing through the multi-outlets and the internal and external temperatures of the multi-outlets. It can be easily confirmed, and relates to a power-saving intelligent multi-outlet for fire prevention to minimize the power consumption of the power conversion means for self-control.
According to the National Emergency Management Agency statistics, 35% of the fires in buildings are accounted for by electrical agents, and 70% of them are electrical fires due to overload or leakage of electric heating devices. There is an urgent need for measures to block the problem.
However, since the conventional multi-outlet is used in the form of connecting a plurality of electrical and electronic devices after connecting to the wall outlet or the system box embedded in the floor, the over-current exceeding the energizing current of the multi-outlet can flow Furthermore, the branched outlet or system box is divided into a plurality of plus sockets, so that the current flowing through the outlet or system box may exceed the rated current. Such overcurrent generates heat in the wire and may cause a short circuit accident by lowering the insulation strength of the wire sheath due to the heat generated.If an overcurrent persists, it may eventually be damaged due to deterioration of the wire sheath and cause an electric fire due to a short circuit accident. There might have been a problem.
In addition, since the conventional multi-outlet is used in a state exposed to the floor, there is a possibility that the fire may be damaged by heat when the fire occurs, there is also a problem that can be extended to an electrical accident due to short circuit of the internal wire due to the damage. .
In addition, the conventional multi-concentration, if you want to know the current supply current, there is a difficulty to calculate and check the capacity of the connected household appliances, if the current flows in the state that exceeds the rated current but does not need to cut off immediately, That is, in the case where current generally flows in the range of 100% to 120% of the rated current, there is a problem that leads to an accident because the situation cannot be informed even though a countermeasure must be taken.
On the other hand, in general, electrical and electronic devices using the remote control are in a standby state for receiving a transmission signal of the remote control even when the operation is stopped, so that even if the operation is stopped, it consumes a certain amount of power. If not, no-load power loss occurs in the internally mounted transformer, and itself consumes power even in the standby state for re-response, so that uninterrupted current of standby power flows through the multi-conductor to which such equipment is connected. Recently, various multi-outlets have been developed to block such standby power.
However, the multi-outlet that can cut off standby power supplies separate power to the control means that cuts off the standby power. In the conventional multi-outlet, there is a problem that standby power is consumed even in the power supply means. In other words, an unwanted power loss occurred even in the configuration itself to block standby power.
Therefore, at a time when the necessity of green growth and energy saving is emphasized recently, it is urgent to develop a power-saving multi-outlet that can solve the above problems.
Therefore, an object of the present invention, when the internal temperature of the multi-outlet or the external temperature of the multi-conductor reaches a dangerous temperature, it operates to prevent damage to the multi-outlet and secondary accident spread, and can cut off the electricity in response to overload, short circuit and overheating It is to provide a power saving intelligent multi-outlet for fire protection.
Another object of the present invention is to provide a power saving intelligent multi-outlet for fire prevention that can easily check the status information of the multi-outlet by using the multi-outlet itself, thereby facilitating management of the multi-outlet.
Still another object of the present invention is to provide a fire protection intelligent multi-conductor for preventing fire while minimizing power consumption by detecting standby current and minimizing power consumption.
In order to achieve the above object, the present invention provides a

In addition, the present invention outputs a current value, a wire temperature value, an external temperature value, and the like in a constant state, and thus has an advantage of easily checking the state of the multi-outlet.
In addition, the present invention, since the configuration for detecting the standby current and the configuration for detecting the constant current is provided separately, it is possible to obtain a more accurate sense current value by designing the configuration to match the size of the detection current, and also the leakage current By sensing, the operation corresponding to the magnitude of the current can also be performed without error.
In addition, the present invention is configured to minimize the power consumption of the power supply unit for supplying a direct current electricity to the internal control configuration, it is also possible to reduce the loss of standby power by the internal control configuration, especially when the power is cut off, that is, the switching unit ( 80) further reduces the power loss of the electric device by further minimizing the power loss, and also has the advantage of reducing the power consumption of the multi-conductor itself.

In the following description of the present invention, if it is determined that a detailed description of a related known function or known configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

In addition, the resistor R2 and the variable resistor VR1 are connected in series so that the resistor R2 is connected to the positive line (V +) and connected in parallel to the two lines (V +, V0), and the variable resistor lead end of the variable resistor VR1 is the diode D5. The capacitor C2 is connected to the capacitor C2 via V, directly connected to the timer T1, and divided by the variable resistor VR2 and applied to the timer T1.
In this manner, when the rectified wave rectified to the capacitor C2 is supplied for a predetermined time through the resistor R2 and the variable resistor VR1, and a certain amount or more of the charge is charged to the capacitor C2, the control signal is input to the timer T1 through the variable resistor VR2. In this case, the timer T1 outputs a pulse signal for turning on the transistor Q1 via the resistor R3 and the diode D7. Next, the timer T1 repeats the process of discharging the capacitor C2 and then recharging it. The RC constant set to the resistor R1, the variable resistor VR1 and the capacitor C2 determines the pulse period and pulse width of the switching signal output from the timer T1. On the other hand, since the charge and discharge time intervals are determined according to the voltage of electricity supplied from the variable resistor VR1, the capacitor C2 has a pulse period and a pulse width of the timer T1 for setting the magnitude of the voltage divided by the variable resistor VR1. It should be adjusted accordingly.
