Description

[0001] Electricity Information Management System [

The present invention relates to an electrical information management system for monitoring a distribution board or an electrical switchboard that supplies electricity to a facility, and more particularly, to an electrical information management system for monitoring electrical information such as overload, short circuit, A device; A monitoring terminal device capable of storing and monitoring abnormality signals received from the electrical information collecting device in real time in a database; And an electronic information management system.

In general, a distribution board installed in a customer is also referred to as an electric distribution board or an electric distribution board. In a conventional distribution board, only an electric breaker is provided to cut off electric power from the power supply when an overcurrent or a leakage current flows.

The conventional distribution panel is used for the purpose of shunting electric lines, and is provided with an electric circuit breaker so that only the simple operation of turning on or off the electric circuit breaker is possible.

Further, according to the conventional distribution panel, it is impossible to know the abnormality (erroneous operation or negative operation) of the electric circuit breaker itself, and also there is no display function and the overload state of the load side line or the state of the short circuit can not be known, It is not possible to generate an alarm so that the customer can prevent such an accident in advance. In addition, the conventional distribution panel does not have the function of transmitting the information about the operation of the electric breaker, so that it is impossible to monitor whether or not the safety operation is performed at a remote place.

Therefore, in the case where a power panel supplied only to such a simple electric circuit breaker is supplemented to monitor a power state supplied to a customer, and an abnormal state such as a short circuit, an overload or a power failure occurs or the possibility becomes high, A distribution state monitoring device capable of generating an alarm to be able to generate a warning is proposed as a utility model application No. 20-2000-17114. The conventional power distribution state monitor includes a power distribution state signal detector for detecting a power distribution state signal from a current flowing through a power line, a signal for generating a drive signal for driving the state display by receiving the power distribution state signal, And a status indicator for generating an alarm that the user of the customer can perceive visually or audibly in response to a power state such as a short circuit, an overload or a power failure.

In the conventional power distribution status monitor having the above configuration, it is possible to monitor the amount of current supplied to the customer by the power line on the load side in real time by the power status signal detector, and the amount of current is the rated current of the electric circuit breaker Judging that a caution or a dangerous state has been reached when the detected amount of electric current reaches a predetermined ratio of these rated values, Audible alarms are issued. According to the conventional power distribution status monitor, it is possible to prevent electric fire accidents and electric shock accidents due to electric leakage or overcurrent.

However, the above-mentioned conventional power distribution status monitor monitors an electric power situation in a single distribution panel and issues an alarm. In the case of a building in which a plurality of distribution panels are installed, there is a problem that the user must individually check the power status of each distribution panel there was. Therefore, in the case of a large-sized building, there is a problem in that it is practically difficult to prevent an accident caused by an overcurrent or a short-circuit, unless the conventional power-distribution-state monitor is installed.

In addition, since the conventional power distribution state monitors operate independently of each other, there is a problem in that, when power demand of a specific area is increased, efficient power distribution can not be achieved by cutting off power of other idle areas.

In addition, despite the fact that many researches and developments have been carried out on products to prevent fires caused by electrical defects, it is a reality that similar electric fire accidents are occurring continuously because electric fire can not be efficiently prevented. Most fire protection products detect signals after the occurrence of electrical faults that lead to a fire, so they can not significantly reduce or prevent electric fires caused by them, and accidents such as power outages are repeatedly caused. The basic element of the electric fire prevention system is to detect and analyze the signal when there is an accurate correlation with the cause of the electric fire in the electric facility. .
