Abstract
The utility model relates to a novel power failure double color light indicator. A 110k ohms resistance voltage reducing current limit, a commutating diode commutation, a 47UF pressure 16V electrolytic capacitor filtering and a forward and reverse parallel encapsulation are arranged on an elongated circuit board. A double color light emitting diode with only two leading feet is connected with the two ends of a single pole air switch or a 220V power supply live wire fuse in parallel through two lead wires.
Description
Affiliated technical field:
The utility model is a kind of device that relates to the glory indication, is used for the two ends of one pole air switch, 220 volts of power firestreaks.
Background technology:
Now air switch, the residual current circuit breaker of generally using all requires every two weeks or must dial a routine inspection with hand in one month, and this is actually does not accomplish that aging or oxidation and rusting just can not very accurately trip and put in place when them.Have only fuse can accomplish very, thus fuse will exist forever can not be alternative fully.In distribution box except residual current circuit breaker, the one pole air switch also very generally uses, because residual current circuit breaker is too sensitive, it is a milliampere level, air switch is the peace level, lighting circuit generally is to use the one pole air switch, all there is not the air switch tripping operation now in the power supply box, the blowout indicating device, when the lighting circuit outage, as dark as a stack of black cats, the maintenance personal does not know that indoor or outdoor distribution box goes wrong, must hold flashlight and be checked through outdoorly,, just must all dial one time by each air switch if air switch does not jump to the position from indoor, each chopper switch is all opened and checked one time, and is time-consuming like this, effort influence again the circuit working that does not cut off the power supply.Just can rapidly, accurately find the fault point if load onto " double-colored glory indicating device cuts off the power supply ", make circuit recover normal.
Summary of the invention:
For one pole air switch tripping operation or when tripping not in place, 220 volts power firestreak blowouts, under situation as dark as a stack of black cats, the maintenance personal a long way off, with eye just can direct failure judgement point an accurate position.
The technical scheme that the utility model adopted is: a 110K Ohmic resistance step-down current limliting, rectifies of serial connection, forward and reverse parallel connection of serial connection (or claiming that anode and anode, negative electrode are in parallel with negative electrode) are installed on the strip wiring board encapsulate, the dichromatic LED that has only two lead-out wires, the electrochemical capacitor of a withstand voltage 16V of 47UF is in parallel with dichromatic LED, with the two ends of two leads and one pole air switch or 220 volts of power firestreak fuses and connect.When the one pole air switch, 220 volts of power firestreak fuses are normal, " double-colored glory indicating device cuts off the power supply " dead electricity is not worked, when the tripping operation of one pole air switch, trip not in place or 220 volts of main fuses when blowing, electric current is through the resistance step-down of 110K ohm, current limliting, rectifies, 16V electrochemical capacitor filtering that 47UF is withstand voltage (does not have the electric capacity dichromatic LED can only send out light a kind of, as ruddiness), dichromatic LED, load in the circuit (the general total parallel resistance of home circuit has only tens---hundreds of ohm, at most can be above 1-2 kilohm) constitute the loop, two kinds of glories that dichromatic LED sent replace fast, as red indigo plant, red green, unusually eye-catching in the dark, the guiding maintenance personal accurately finds the fault point rapidly, and about 2 milliamperes of the electric current of flow through " double-colored glory indicating device cuts off the power supply " can not constitute a threat to the maintenance personal, can not make the electrical work in the circuit yet, very safe.
The beneficial effects of the utility model are: when outage, even in the dark, the maintenance personal can accurately find the fault point in larger distance, the row's of giving barrier provides great convenience, and " double-colored glory indicating device cuts off the power supply " very economical, simple in structure, durable, be easy to promote.
Description of drawings: the utility model is further specified below in conjunction with accompanying drawing and example:
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is " double-colored glory indicating device cuts off the power supply " embodiment sectional structural map.
In Fig. 1,2, the 1st, one pole air switch or 220V power firestreak fuse, the 2nd, the 110K Ohmic resistance, the 3rd, rectifier diode (available IN4007) the 4th, 47UF is withstand voltage 16V electrochemical capacitor, the 5th, forward and reverse parallel connection (or claiming that anode and anode, negative electrode are in parallel with negative electrode) encapsulates, the dichromatic LED that has only two lead-out wires, the 6th, the load in the circuit (various electrical equipment, electric light etc.).
Embodiment:
In Fig. 1,2 at the two ends of one pole air switch, 220V power firestreak fuse and connect a string double-colored glory indicating device.The i.e. electrochemical capacitor of the resistance of a 110K ohm, a rectifier diode (IN4007), a withstand voltage 16V of 47UF, a dichromatic LED that has only two lead-in wires, they can be according to actual needs, be installed on the circuit board of strip, draw two leads and be connected on the two ends of one pole air switch, 220V power firestreak fuse respectively, wiring board can be installed in the one pole air switch directly over or the next door of 220V power firestreak fuse.
Claims (1)
1. double-colored glory indicating device of novel outage, it is characterized in that: the resistance step-down current limliting that a 110K ohm is installed on the wiring board of strip, be connected in series a rectifies, be connected in series a forward and reverse encapsulation in parallel, have only the electrochemical capacitor filtering of the dichromatic LED of two leading foots, a withstand voltage 16V of 47UF in parallel, with two leads and one pole air switch or 220 volts of power firestreaks and connect with dichromatic LED.
