Title: Improvements in or relating to electric protective systems
IPC: H02H3/16
Filed: 1949-01-26
Abstract: 656,997. Protective cut-out arrangements. ELECTRO METHODS, Ltd., and BUTCHER, F. E. Jan. 26, 1949, No. 2122. [Class 38(v)] An arrangement for the protection of an appliance such as a portable electric tool, has a normally closed electromagnetic switch 3, 10 which opens the supply circuit in the event of an earth fault, and a normally energized electromagnetic switch 14, 24 which when de-energized by the failure of the earth connection 8 of the appliance 7, opens the supply circuit. The coil 10 of the first switch is of high impedance and is connected to earth and to the centre tapping or other suitable tapping of the secondary winding 5 of a transformer T. A fault to earth from conductors 22, 23 or the load 6 completes the circuit for the energization cf the coil 10 which opens contacts 3. The coil 14 maintains the contacts 24 of the second switch closed, so long as it is energized from the tertiary winding 12 of the transformer T by way of a switch 21 and the safety earthing connection 8 of the appliance 7. Thus on breakage or failure of the connection 8, the contacts 24 are opened. The coil 14 has a low impedance so that the contacts 24 could not be maintained closed by earth fault current through the highimpedance coil 10 should the connection 8 become defective at the same time as the fault occurs. A test circuit for checking the earthing connection 8 comprises a test socket 19 with a contact 18 connected to a pilot lamp 16 and a shunt 17 which are connected to the winding 12. To test the connection, the earth pin of the plug (not shown) to which the earth lead 8 is connected is engaged in the socket contact 18, and when the appliance is placed on an earthed support 20, a circuit is completed from the tertiary winding 12 through the lamp 16 and shunt 17, through the lead 8, the casing of the appliance 7, and support 20 to earth. The lamp 16 is lit and remains so if the lead 8 can carry the comparatively heavy current through the shunt 17.
