Photodiode 120 plug load (electrical equipment) according to electrical source socket 10 after loop current (loopcurrent) and the comparative result of rated current (ratedcurrent) of electrical source socket 10 send the light of different colours.
In the following description, it is assumed that the rated output (ratedpower) of electrical source socket 10 is 2500 watts, then the rated current I0 of electrical source socket 10 is 2500/220 ampere, is about 11.40 amperes. If not having electrical equipment insertion electrical source socket 10, then the loop current I of electrical source socket 10 is 0 ampere, and photodiode 120 can not be luminous. If loop current I is not 0 and is less than I1, then photodiode 120 sends green glow, represents load current situation normal, and electrical source socket 10 operates normal without anxiety. If loop current I is not less than I1 and is less than I2, then photodiode 120 sends yellow light, represents load current relatively big, should not insert high-power electric appliance again. If loop current I is not less than I2, then photodiode 120 sends ruddiness warning, represents electrical source socket 10 close to overcurrent, should not insert electrical equipment again, even need to extract the electrical equipment of relatively high power. In the present embodiment, I1 is the 85% of rated current I0, about 9.7 amperes, and I2 is the 95% of rated current I0, about 10.8 amperes. It should be noted that the number of the coloured light kind of above-mentioned photodiode 120 and I1 and I2 and per-cent are only exemplary, it does not mean to restriction the present invention.
For Fig. 2��Fig. 4, the situation in electrical source socket 10 use is described below. As shown in Figure 2, when power is the electrical equipment 20 of 60 watts, a such as notebook computer, when plugging supply socket 111, now loop current I=60/220 �� 0.27 ampere, is less than I1, then photodiode 120 sends green glow. As shown in Figure 3, when there being power to be the electrical equipment 30 of 2200 watts again, a such as electromagnetic oven, when plugging supply socket 112, now loop current I=(60+2200)/220 �� 10.27 amperes, is greater than I1 and is less than I2, and therefore photodiode 120 sends yellow light. As shown in Figure 4, when there being power to be the electrical equipment 40 of 150 watts again, a such as televisor, when plugging supply socket 113, now loop current I=(60+2200+150)/220 �� 10.95 amperes, is greater than I2, and therefore photodiode 120 sends ruddiness warning close to overcurrent.

Amperometric 131 detects the loop current I of electrical source socket 10, and loop current I exports to A/D converter 132. Loop current I is carried out A/D by A/D converter 132 to be changed so that loop current I to be converted to detection numerical value, and exports detection numerical value to comparer 133. Comparer 133 numerical value storage A1 and A2, wherein A1 is that electric current I 1 changes the numerical value obtained through A/D, and A2 is that electric current I 2 changes the numerical value obtained through A/D. Comparer 133 compares detection numerical value and A1 and A2 with the size of comparison loop electric current I and I1 and I2, and exports comparative result to D/A transmodulator 134. If detection numerical value is not 0 and is less than A1, then comparer 133 output detections numerical value is to D/A transmodulator 134. If detection numerical value is not less than A1 and is less than A2, then comparer 133 exports A1 to D/A transmodulator 134. If detection numerical value is not less than A2, then comparer 133 exports A2 to D/A transmodulator 134. D/A transmodulator 134 compared result carries out D/A conversion and comparative result has been converted to corresponding voltage signal, and this voltage signal is applied the two end electrodes in LED120, makes LED120 send different coloured light according to the difference of the voltage size of voltage signal.

In step slo, electrical source socket 10 is plugged in load (electrical equipment). In step S20, the loop current I of detection electrical source socket 10, such as, by amperometric 131 measure loop electric current I. In step s 30, whether comparison loop electric current I is less than electric current I 1, such as first by A/D converter 132, loop current I is carried out A/D to change so that loop current I to be converted to detection numerical value, then compare detection numerical value and the numerical value A1 being stored in comparer 133 by comparer 133, wherein numerical value A1 is that electric current I 1 obtains through A/D conversion. If loop current I is less than electric current I 1, then, as shown in step S50, LED sends green glow. If loop current I is not less than electric current I 1, then as shown in step S40, whether comparison loop electric current I is less than electric current I 2, such as, compare detection numerical value and the numerical value A2 being stored in comparer 133 by comparer 133, and wherein numerical value A2 is that electric current I 2 obtains through A/D conversion. If loop current I is less than electric current I 2, then as shown in step S60, LED sends yellow light. If loop current I is not less than electric current I 2, then, as shown in step S70, LED sends ruddiness.
Fig. 9 show the schematic diagram of electrical source socket 90 according to another embodiment of the present invention.

LED121��126 are used for representing the load current state of each supply socket 111��116 respectively, and that is, LED121��126 are used for representing the loop current of each supply socket 111��116 and the magnitude relationship of rated current respectively. Citing, it is assumed that the rated output of electrical source socket 90 is identical with electrical source socket 10, and the luminous principle of LED120 is identical with the LED120 of Fig. 1. When supply socket 111 plugged by the electrical equipment 20 that power is 60 watts, now the loop current I of electrical source socket 90 is about 0.27 ampere, it is less than I1, then photodiode 120 sends green glow, and the loop current I11=60/220 �� 0.27 ampere of supply socket 111, be less than I1, then photodiode 121 sends green glow. When except electrical equipment 20, power is had to be that the electrical equipment 30 of 2200 watts is when plugging supply socket 112 again, now loop current I=(60+2200)/220 �� 10.27 amperes of electrical source socket 90, it is greater than I1 and it is less than I2, therefore photodiode 120 sends yellow light, and the loop current I12=2200/220=10 ampere of supply socket 112, it is greater than I1 and it is less than I2, therefore photodiode 122 sends yellow light. When except electrical equipment 20 and 30, power is had to be that the electrical equipment 40 of 150 watts is when plugging supply socket 113 again, now electrical source socket 90 loop current I=(60+2200+150)/220 �� 10.95 amperes, it is greater than I2, therefore photodiode 120 sends ruddiness, and the loop current I13=150/220 �� 0.68 ampere of supply socket 113, being less than I1, then photodiode 123 sends green glow. Therefore, when electrical source socket 90 plugged by electrical equipment 20,30 and 40 simultaneously, photodiode 120 sends ruddiness, photodiode 121 sends green glow, photodiode 122 sends yellow light, photodiode 123 sends green glow, and the electrical equipment 30 therefore can learnt in supply socket 112 by the yellow light of photodiode 122 is high-power electric appliance, it may also be useful to person can preferentially pull out electrical equipment 30 accordingly to avoid electrical source socket 90 overcurrent.
