Embodiment
Below in conjunction with specific embodiment, the utility model is further elaborated, but protection range of the present utility model not limited by specific embodiment, is as the criterion with claims.In addition, with without prejudice under the prerequisite of technical solutions of the utility model, any change that the those of ordinary skill in the art done the utility model easily realize or change all will fall within right of the present utility model.
Embodiment 1
Fig. 1, the safe electricity-getting converter of replaceable plug of the present utility model shown in 2, comprise wiring board 15, its wiring board 15 is connected with transducer control box 1 by wire, this transducer control box 1 draws live wire 4 respectively, zero line 5 and ground wire 3, described live wire 4, the termination of zero line 5 is respectively equipped with gang socket 6, the connection wye 8 of this gang socket 6 and crossover sub, banana joint 9, any one in crocodile mouth joint 10 or pin contacts 11 plugs, the termination of described ground wire 3 is connected with crocodile mouth card 2, described transducer control box 1 is respectively equipped with fuse and disconnects indicator light L1 14, electric indicator light L3 12 and zero live wire is had to meet anti-indicator light L2 13.
The above-mentioned structure stating transducer control box 1 is as follows: current-limiting resistance R3, have electric indicator light L3 12 series circuit to be connected across between the live wire 4 of input power, zero line 5; Current-limiting resistance R1, fuse disconnect indicator light L1 14 series circuit and are connected across fuse 16 two ends; Between the input that fuse 16 is connected on power firestreak 4 and output; Current-limiting resistance R2, zero live wire connect anti-indicator light L2 13 series circuit and are connected across between the zero line 5 of input power, ground wire 3.
Operation principle of the present utility model
:
When the utility model specifically uses, first according to circumstances select suitable crossover sub 7, then ground wire 3 is connected to reliable ground place, optional playing is detected zero line live wire correctness and is provided the effect of ground connection for electrical appliance.
Carefully zero line 5, live wire 4 are connected on power supply respectively, now, if power supply has electricity, then have electric indicator light L3 12, zero live wire to connect anti-indicator light L2 13 and fuse and disconnect indicator light L1 14 and should extinguish.
Do not have voltage to export if in use find, and fuse disconnection indicator light L1 14 light, then should be fuse 16 and fuse, now should first check that power consumption equipment occurs with or without short-circuit conditions, if check errorless, then should be overload, should change the fuse adapting to load.
1, Power supply belt Electricity Functional realize principle:
When the safe electricity-getting converter of the utility model replaceable plug is connected on power supply, if power supply is charged, namely in Fig. 2 between live wire 4, zero line 5 with voltage, then the R3-L3 series circuit two ends be connected across therebetween are applied in voltage.R3 is the current-limiting resistance having electric indicator light L3 12, and L3 should light under current-limiting resistance protection.Work as power loss, lose voltage between live wire, zero line, L3 indicator light extinguishes.
2, blown fuse deixis realize principle:
When the safe electricity-getting converter of the utility model replaceable plug is connected on power supply, if electrical appliance is short-circuited or overload causes fuse 16 to fuse, now in Fig. 2, live wire 4 output and zero line 5 output can be considered short circuit (R1+R
l1>>R
load), then the supply voltage overwhelming majority is applied in the circuit of R1-L1 composition, and R1 is the current-limiting resistance that fuse disconnects indicator light L1 14, and L1 should light under current-limiting resistance protection.
3, zero line, live wire break links deixis realize principle:
When the safe electricity-getting converter of the utility model replaceable plug is connected on power supply, if zero-power line 5 live wire 4 connects instead, then in Fig. 2 between zero line 5, ground wire 3 with voltage, then the R2-L2 series circuit two ends be connected across therebetween are applied in voltage.R2 is the current-limiting resistance that zero live wire meets anti-indicator light L2 13, and L2 13 should light under current-limiting resistance protection.When power firestreak, zero line connect correct, answer no-voltage between zero line, ground wire, L2 13 indicator light extinguishes.
