Abstract
It the utility model is related to three sockets and simply examine Teaching instrument, suitable for teaching and electricity consumption safety check.This it is practical it is new disclose three sockets simply teach instrument have zero, fiery three horizontal paths, wherein between zero, live wire tail end, be connected by circuit, there is switch K1 and electrical verification neon bulb L1 on the line；Be connected between zero, live wire caudal part by two level circuit, midpoint is also connected with ground wire on the circuit, the circuit with ground circuit intersection point the left side be provided with switch K3 and electrical verification neon bulb L3, with ground circuit intersection point on the right of be provided with switch K2 and electrical verification neon bulb L2；Phase connecting lines are set between the ground, live wire above two level circuit, switch K4 and 10W incandescent lamps L4 is set on the circuit.The utility model can insert ground normalized checking with three, and fire, zero line are whether reversed, and whether leakage switch is effective, strengthen safety utilization of electric power.
Description
Technical field
Originally it is practical to be newly related to the civilian electric safety detector of home dwelling
Background technology
With the continuous development of social science and technology, science and technology, production, household electricity are more and more, people's too busy to get away electricity, that
It is dangerous caused by electricity consumption is possible also to increase, get an electric shock and the harmfulness of electric calamity is also increasing.China is dead because getting an electric shock every year
About 8000 people.Wherein most people dies from electric shock electric leakage.How because of electric leakage electric shock and dead population is reduced to greatest extent
How to strengthen three socket secure knowledge educations, strengthen three and insert ground normalized checking, it is reversed whether fiery zero line has, and electric leakage is opened
Whether pass is effective, so as to improve Electrical Safety
The content of the invention：
A kind of three sockets that are to provide of the purpose of the present invention simply examine Teaching instrument, and it can strengthen the religion of three socket secure knowledge
Educate, strengthen three and insert ground normalized checkings, fire, that whether zero line has is reversed, and whether leakage switch is effective, so as to improve Electrical Safety.Three
Socket, which simply examines Teaching instrument, zero, fiery three horizontal paths, wherein between zero, live wire tail end, be connected by circuit, online
Lu Shangyou switchs K1 and electrical verification neon bulb L1；It is connected between zero, live wire caudal part by two level circuit, the midpoint on the circuit
Also be connected with ground wire, the circuit with ground circuit intersection point the left side be provided with switch K3 and electrical verification neon bulb L3, with ground circuit intersection point
The right be provided with switch K2 and electrical verification neon bulb L2；Phase connecting lines are set between the ground, live wire above two level circuit, in the line
Switch K4 and 10W incandescent lamps L4 is set on road.
The utility model has the advantages that ground normalized checking can be inserted with three, fire, zero line are whether reversed, and whether leakage switch has
Effect, strengthen safety utilization of electric power.
Brief description of the drawings：
Fig. 1, circuit configurations schematic diagram of the present utility model.
Specific embodiment：
According to Fig. 1, the socket of the utility model three, which simply examines Teaching instrument, zero, fiery three horizontal paths, wherein
0th, between live wire tail end, it is connected by circuit, there is switch K1 and electrical verification neon bulb L1 on the line；Between zero, live wire caudal part
It is connected by two level circuit, midpoint is also connected with ground wire on the circuit, and the left side of the circuit and ground circuit intersection point is provided with
Switch K3 and electrical verification neon bulb L3, with ground circuit intersection point on the right of be provided with switch K2 and electrical verification neon bulb L2；On two level circuit
The ground of side, phase connecting lines are set between live wire, switch K4 and 10W incandescent lamps L4 is set on the circuit.
Principle of the present utility model is as follows：
In circuit：L1, L2, L3 are electrical verification neon bulbs, and L4 is 10W incandescent lamps, zero, fire, represent respectively three plugs it is left, in,
Right three plugs.Routine is when connecing pair：Ground wire in the left right live wire of zero line.
Quick determination method：
When only closing K1, when K2, K3,
1st, such as L1, L2, L3 do not work, and circuit is normal；
2nd, such as L1, L2, L3 is bright, and ground wire is not grounded；
3rd, such as L1, L3 is bright, and L2 does not work, and fiery zero line is reversed；
All do not work, out of power or live wire do not connect.
Claims (1)
1. three sockets simply examine Teaching instrument, it is characterized in that three sockets simply examine Teaching instrument and have zero, fiery three horizontal paths, its
In between zero, live wire tail end, be connected by circuit, have on the line switch K1 and electrical verification neon bulb L1；Zero, live wire caudal part it
Between be connected by two level circuit, midpoint is also connected with ground wire on the circuit, the circuit with ground circuit intersection point the left side set
Have switch K3 and electrical verification neon bulb L3, with ground circuit intersection point on the right of be provided with switch K2 and electrical verification neon bulb L2；In two level circuit
