Accompanying drawing explanation
Fig. 1 is the external structure of a kind of earth leakage protective device of the present invention.
Fig. 2 is the internal circuit diagram of a kind of earth leakage protective device of the present invention.
Wherein: 1 housing, 2 socket covers, 3 sockets, 4 lampshades, 5 lampets, 6 loads, 7 transformers, 8
Master switch, 9 electrical apparatus releases, 10 slots, 11 plugs.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Detailed description of the invention, is expanded on further the present invention.
A kind of earth leakage protective device, including being provided with the housing 1 of plug and socket, described socket 3 includes bipod socket 3 and three
Foot socket 3, it is characterised in that: also include earth leakage protective device, described earth leakage protective device include master switch 8, transformer 7,
Electrical apparatus release 9 and load 6, described transformer 7 is a ring-shaped core, and master switch 8 connects single-phase two wires power supply, by master switch 8
Two wires of output are also cross ring-shaped core, then are connected to load 6, from two wires and the bipod of socket 3 of load 6 output
Connecting, the remaining foot of three-pin socket 3 connects PE line, and described plug 11 is three-pin plug 11, plug 11 and the company of housing 1
Connecing position and be provided with buckle, housing 1 is provided with draw-in groove and slot 10, and plug 11 is rotatable to be put in slot 10, and earth leakage protective device does not has
When having use, convenient for collecting, described housing 1 top is provided with lampet 5, and lampet 5 is connected with two wires of load 6 extraction, rises
To illumination and the effect of prompting, described lampet 5 is provided with lampshade 4, prevents lampet 5 from glittering in night dazzling, on described socket 3
Being provided with socket cover 2, socket cover 2 is rotatably connected with housing 1, prevents rainwater from entering socket 3, thus leaks electricity.Master switch 8 manually closes
After conjunction, leakage current Id=0, now equal in magnitude, in opposite direction through main circuit current I1 and I2 on ring-shaped core, I1+I2
=0.Magnetic flux the Φ 1 and Φ 2 that two electric currents produce respectively in ring-shaped core is equal in magnitude, in opposite direction.The synthesis produced in iron core
Magnetic flux Φ 1+ Φ 2=0, therefore another Secondary Winding loop on transformer 7 ring-shaped core does not has induced voltage, U2=0, electrical apparatus release
9 are failure to actuate.When there is electric leakage, generation leakage current Id, Id=I1+I2, the resultant flux Φ now produced in ring-shaped core=
Φ 1+ Φ 2=Φ d, then upper Secondary Winding loop unshakable in one's determination produces induced voltage U2.When leakage current increases to predetermined numerical value,
Electrical apparatus release 9 action, the snap close of master switch 8 is released and disjunction circuit.The earth leakage protective device of fast high-sensitive degree occurs from circuit
Fault to master switch 8 disjunction process quickly, even if there occurs the person electric shock, when shock current does not the most cause fatal harm
Time, protector the rapidest disjunction circuit, protect personal safety.
It is an advantage of the current invention that: this kind of earth leakage protective device, described plug 11 is three-pin plug 11, plug 11 and housing
