Abstract

A display device capable of easily and intuitively displaying the power status of the distribution panel by simply displaying the state of power supply in the distribution panel outside the distribution panel without using the multimeter tester. If two lights are installed on the outside of the distribution board and the power status indicator lights up, it means that the power is supplied properly after the short parking period in the distribution board. If the ground status indicator is on, the power supplied from the distribution board is properly grounded .

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

More particularly, the present invention relates to a distribution panel power status display device for displaying a power status (energization and grounding status) of a distribution panel for supplying commercial AC power to the outside.

A distribution board is an electric distribution apparatus that collects and distributes electricity in a building. In general, a distribution board is composed of a main circuit breaker for wiring, a circuit breaker for each branch circuit for branching therefrom, and an earth leakage circuit breaker. That is, in the case of 380V / 220V three-phase four-wire type, three phases R, S and T are composed of a hot line, a neutral line and a ground line connected to the ground.

Traditionally, as a method of confirming the power supply status of a panel installed in a building, there is a method of checking whether the breaker is opened by opening the panel board or a voltage is directly measured by a multimeter tester to check whether the power is turned on Method, or a method of indirectly confirming by lighting or operation of a lamp or load device used as a load.

Also, as a method of confirming the grounding state of the distribution board, the door of the distribution board is opened and the voltage or resistance value is directly measured by the multimeter tester to check whether the ground is grounded.

In the case of the conventional distribution panel, there is no special indicator lamp in the distribution panel enclosure. Therefore, in order to check the power state (energization and grounding state), it is necessary to open the door of the distribution panel and directly measure the voltage or resistance value using a multimeter tester. It is always exposed to danger such as electric shock or short circuit due to measurement in the state where power is applied to the distribution board.

On the other hand, in the following two prior art documents, it is disclosed that a structure for power supply inspection is applied to a distribution board itself. However, they monitor and control electrical parameters at advanced levels such as leakage detection, overload of load device, cause of breaker, shutdown time, malfunction, malfunction detection, insulation resistance value, fire temperature measurement, remote monitoring and control A complicated configuration is required and an expensive cost is required.

Utility model registration public disclosure 2003-0064548 (public on August 2, 2003) Utility model registration 20-0457637 (Notice of December 28, 2011)

The inventor of the present invention can easily and intuitively use the panel board power supply in a casual case in which it is not necessary to monitor and control the advanced electric parameters while avoiding the danger of using the multimeter tester, State labeling technology was developed and the present invention was completed.

Conventional panel monitoring technology monitors the power state at a high level. However, in the case where this level of surveillance is not actually needed, the above-described prior art configuration is over-specification and provides unnecessary functions and is expensive. There is a need for a simple, low-cost intuitive status display.

Thus, the inventor of the present invention can easily and intuitively display the power state (energized and grounded state) of the distribution panel by simply displaying the state of power supply in the distribution panel outside the distribution panel without using the multimeter tester A display device was devised.

In order to solve the above problems, according to the present invention, there is provided a distribution panel display apparatus, comprising: a display unit for displaying a state of lighting of two indicator lights installed on a distribution panel to which power is supplied without using a multimeter tester, And display it intuitively. That is, if the power-on indicator lights up, it means that the power is supplied properly after the parked period in the current panel, and when the grounded status indicator is lit, it indicates that the power provided by the present panel is properly grounded.

More specifically, the present invention relates to a terminal device comprising a top end connected to a commercial line of a power source, a neutral terminal connected to a neutral line of the power source, and a ground terminal connected to a ground line of the power source, A rectifier diode D to which an anode is connected to the upper end, a resistor R1 to which a first end is connected to the neutral terminal, and a resistor R2 to which a first end is connected to the ground terminal, A rectifying part for limiting the current by using the rectifying part; A light emitting diode LD1 forward-connected between a cathode of the rectifying diode D of the rectifying unit and a second end of the resistor R1; a light emitting diode LD2 forwardly connected between the cathode of the rectifying diode D of the rectifying unit and the second end of the resistor R2; And a display unit for displaying the energized state and the grounded state of the power supply state provided in the distribution board.

In this circuit configuration, the upper end, the rectifying diode D, the light emitting diode LD1, the resistor R1, and the neutral terminal constitute a closed circuit in which the current entered through the upper terminal falls into the neutral terminal. In addition, the upper end, the rectifying diode D, the light emitting diode LD2, the resistor R2, and the ground terminal constitute a closed circuit in which the current entered through the upper end falls to the ground terminal.

The two light emitting diodes of the display unit, that is, the light emitting diodes may be implemented by light emitting diodes that emit light of different colors, but the present invention is not limited thereto.

According to the present invention, the energization state and the grounding state of the power supply in the distribution panel can be easily identified by a simple circuit configuration. In addition, this power panel power status display device can easily identify intuitively the power state (energized state and grounded state) visually without opening the panel door because it is exposed to the panel board enclosure. The power status can be constantly monitored while operating at a constant cost.

One of the indicators is the energization status indicator 31, and the other is the ground status indicator 32. [ When the energization status indicator 31 is turned on, it means that the power is supplied properly after the short period of parking in the present panel.
