Abstract

PROBLEM TO BE SOLVED: To display the position of a distribution board and the state of a circuit breaker incorporated in the distribution board, even when a power failure occurs due to the disconnection of the circuit breaker or the stoppage of power supply to the distribution board, by using a luminous resin in the handle member of the circuit breaker. SOLUTION: A luminous resin such as the one made by Chemitec Co., Ltd., etc., is used in the handle member of a circuit breaker 1 incorporated in a distribution board 1. Since the luminous resin used has initial luminance (the luminance about 30 seconds after the pallet is irradiated with light from normal light source D 65 for about four minutes with the brightness of about 200±10 Lx after the pellet is kept for about three hours or longer in a state where the pellet is shielded from external light) of about 2,500 mcd/m*m or higher (semipermanent) and afterglow time of about 30 hours or longer (semipermanent), the operator of the distribution board can sufficiently confirm the position of the board at a distance of about 10 m even in the dark and, when the operator approaches the board, the operator can recognize the state of the handle of the circuit breaker 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distribution board incorporating a circuit breaker that emits light when a power failure occurs.

[0002]

2. Description of the Related Art Conventionally, a lighting device is mounted on a distribution board, a circuit breaker incorporated in the distribution board itself has a cut-off display function, and a lighting fixture with a built-in battery that lights up when a power failure occurs. Was attached to a distribution board.

[0003]

However, the lighting device mounted on the distribution board and the circuit breaker having the cut-off display function both take the display power from the power supply of the distribution board.
It is effective for a power failure due to the interruption of the circuit breaker, but does nothing at the time of a power failure of the power supply itself of the distribution board. In addition, a distribution board equipped with lighting equipment with a built-in battery lights up when a power outage occurs and exerts its effect, and it is convenient to remove the lighting equipment from the distribution board and use it as a flashlight, but it is convenient, Control circuitry is required and the instrument itself is very expensive.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to be applied to a case where a circuit breaker incorporated in a distribution board is interrupted due to an overcurrent or a short circuit or a case where power supply to the distribution board is stopped due to a lightning strike or the like. The purpose of the present invention is to provide an inexpensive switchboard that can display the position of the switchboard and the state of the circuit breaker in response to a power outage and can respond quickly.

[0005]

In order to solve the above-mentioned object, the switchboard of the present invention is provided with a light source such as sunlight or a fluorescent lamp for a short time, and a certain time after the irradiation is cut off. The light-emitting resin which continuously emits light is used for the handle member of the circuit breaker. If the circuit breaker incorporated in the distribution board is cut off or if power supply to the distribution board is stopped, a power failure occurs.In the present invention, even during such a power failure, the circuit breaker handle emits light, The position of the switchboard and the state of the circuit breaker are displayed, and a switchboard capable of promptly responding can be provided at low cost. The same effect can be obtained by applying a luminous luminous paint to the handle of the circuit breaker.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings.

FIGS. 1 and 2 are diagrams to which claim 1 of the present invention is applied. As a handle member of a circuit breaker incorporated in a distribution board, a phosphorescent resin, for example, Picarico pellets of Chemitech Co., Ltd. is used. Initial brightness of Chemitec Picarico (lumpy fine powder) (After storing for 3 hours or more in a state where external light is blocked, light of ordinary light source D65 is 200 ± 10 L)
Irradiation at a brightness of x for 4 minutes, the luminance 30 seconds after stopping the irradiation) is 2500 mcd / m * m or more (semi-permanent), and the afterglow time is 30 hours or more (semi-permanent). The position of the distribution board can be sufficiently confirmed from a distance of 10 m, and the state of the handle of the circuit breaker can be known when approaching the vicinity.

FIGS. 1 and 2 are diagrams to which claim 2 of the present invention is applied. Luminescent paint, for example, N Luminescent Luminova of Three Bond Unicom Co., Ltd., is used for the handle of the circuit breaker incorporated in the distribution board. The afterglow characteristic (luminance characteristic after irradiating the light of the ordinary light source D65 with the brightness of 1000 Lx for 30 minutes) of the N luminous luminova is about 100 mcd / m * m after 10 minutes (weather resistance: luminance maintenance rate after 1000 hours) 95% or more), and the same effect as in the case of the phosphorescent resin can be obtained.

[0009]

By implementing the present invention, when a power failure occurs due to interruption of the main or branch circuit or a power failure to the distribution board, the handle of the circuit breaker emits light and the position of the distribution board and The state of the circuit breaker can be easily checked. Also, a method of using a luminous resin as the handle member of the circuit breaker of the present invention or a method of applying a luminous paint to the handle portion of the circuit breaker rather than adding a lighting device, a blocking display function, or a lighting device to the distribution board. But can be done with a much cheaper investment.
