Definitions
- the earth leakage circuit breaker will shut of the power source for the whole panel that contain the fault (in case the earth leakage circuit breaker is on the main breaker of the panel )or the whole circuit that contain the load that have fault (in case the earth leakage circuit breaker is on the circuit branches ),so there is no accurate fault discrimination , beside no continuity of power supply for the rest loads that are in the same circuit of the faulty load but have not leakage .
- the invention provides fast maintenance for the fault , that after isolating the faulty load alone ,it alerts the user for the position of the faulty load at this instant with music and light ,so the user can remove the faulty load safely where it has no power and is isolated and stop the music and light ,and deal with the faulty load separately and maintain it and then put it again to the service without making any effect to other loads.
- This invention provides a separate short circuit and over current protection for each separate load in the circuit ,that in case there is a short circuit fault on a load in a circuit or over current, the invention will isolate this load alone without affecting other loads that are on the same circuit and the location of the load that have fault will be determined by viewing the status of the fuse(burned or not).
- the invention provides an easy new method for earthing of the conductive parts of objects(like metallic water pipes, windows and handrail) with simple cheap maintenance method.
- 16-Live pin in the socket that is connected from the back to the live wire coming from the power source and from the front connected to live line of the load through the plug.
- 17-Neutral pin that is connected from the back to the neutral line coming from the power source and from front to the neutral wire of the load through the plug.
- 21-Alarm siren that gives sound in case of fault for indicating earth leakage current , where this alarm siren is connected in series with the lamp(20) and both are connected across pin 13&14 in relay B. .
- Marconite,.. which is around the rod and makes the resistance at the rod approximately equal to earth resistance (where we install the back box 41 first in the wall and install to it the copper rod 30 and tight it through the connector (31) to the copper wire(29) that is connected to the conductive parts of non electric materials like windows and handrail, then cover the back box 41 by the faceplate 32').
- 34- Earthing compound material like Bentonite , Marconite,.. ) which is around the rod and makes the resistance at the rod approximately equal to earth resistance.
- Imp Note I have executed this invention practically and it's succeeded and there is a video for it available if you request to see it
- the fuse (8) of socket(sl) will open and stop the current in socket (SI) only to stop the short circuit current or the overcurrent( overload) for protecting the load connected to the socket , while other sockets that are in series with socket (SI) will not be effected and the user will have to unplug the load to know the reason of the fault if it's from the load or it's inside the socket it self and then replace the fuse in the socket to reuse the socket again.
- a special designed box (32) (as shown in fig :2 & 2')in the wall that has a back box (41) and a face plate(32') in which we put in it a copper earth rod(30) and join to it a copper wire (31)which is connected to all conductive materials of non electric equipment (27)and also the box contains an Earthing compound material (34)( like
- Bentonite Marconite,.. ) which is around the rod and makes the resistance at the rod approximately equal to earth resistance. so in case there is any static or dynamic charges on conductive parts of non electric equipment ,it will moves through the copper wire(29) to the copper rod(30) or wire inside the box which has low resistance due to earthing compound material(34).
- earthing material can be replaced from time to time or add water to it by moving the cover (33) up through the lip (42) and then return the cover down again (as shown in fig '2 &2') , where there is a grove inside the frame (32') for the cover (33) to prevent what is inside the box from coming outside, to prevent what is inside the box from coming outside, beside the inner lower depth of the box is slightly more than it's outer frame to also prevent what is inside the box from coming outside.
