Embodiment
Below in conjunction with drawings and Examples, the implementation to the present invention is further described.It should be appreciated that described herein Specific embodiment only to explain the present invention, be not intended to limit the present invention.
Referring to Fig. 1, the present invention provides a kind of earth leakage protective device of leakage protecting plug socket, makes plug/socket in inspection Measure ground strip leakage current and during with drain voltage, can thread off rapidly, protect electrical equipment.Shown in Fig. 1 is a kind of comprising three poles The intelligent two systems effective integration of the conversion socket of leakage protection system and intelligence WIFI control systems, earth leakage protective and WIFI exists Use simultaneously together, and mutually protection.
Include jack housing(1,2), latch 4, socket hole position 3, be provided with jack housing zero sequence current mutual inductor with Test loop(Not shown in figure), intelligent circuit board 6, inserted link, relay 8, magnet coil and trip gear 5, and contact, bullet The grade component of piece 7.Dropout holder block 9 is set on intelligent circuit board 6, and dropout bearing 9 is generally plate like, there are a pair pairs thereon Three shell fragments 7 are placed in the trunnion mount of title, dropout holder block, wherein middle shell fragment connection ground wire, under without external force constraint state (It is also simultaneously trip status), the end of shell fragment 7 pops up, now, its end and the contact in dropout holder block 9 10 disconnect.
Trip gear 5 realizes being switched on or switched off for copper shell fragment 7 and contact.Referring to Fig. 2, trip gear 5 includes electromagnetic wire Circle and bobbin 11, iron mandrel 12, lock catch block 14, dropout main shaft 20 and reset key 21, dropout main shaft 20 include rotating cylinder, chuck 22nd, Pivot axle 25, dropout main shaft are crossed in side pressure pin 16, middle presser foot 18, reset key connector 17, the trunnion mount of bearing 9 20 rotating cylinder is arranged in Pivot axle 25 and can be with the center axis thereof of Pivot axle 25.
The connector 13 of iron mandrel 12 is installed in the heavy seat 141 of lock catch block 14, and iron mandrel 12 is located at the interior of magnet coil On centerline hole, magnet coil is arranged on bobbin.When zero sequence current mutual inductor senses that electric leakage occurs, magnet coil is obtained Electricity produces magnetic field, and iron mandrel 12 is moved to the direction away from dropout main shaft 20, and lock catch block 14 is released to iron core away from iron mandrel Rotated in the presence of the constraint of axle, the dropout spring 23 of iron mandrel to trip positions, complete trip action, make shell fragment 7 and contact Disconnect, release danger of hazardous electrical discharges.
Central shaft 25 of the dropout main shaft 20 in the trunnion mount installed in bearing 9 rotates, when it swings, its side pressure pin 16 with Middle presser foot 18 is pressed downward or upwarped, and when presser feet presses to extreme lower position, shell fragment 7 closes with contact, completes fastening action.Lock The side of button block 14 is provided with locking bolt 15, and dropout main shaft 20 sets chuck 22, dropout spring close to one end of magnet coil(Torsion spring) Installed in the outside of chuck 22, moreover, being respectively equipped with wedge 221 and limited block 222 on the outer face of chuck 22, work as dropout The presser feet of main shaft is threaded to extreme lower position, locking bolt 15 and inserted along the wedge surface of wedge 221 between wedge 221 and limited block 222 Space, dropout main shaft 20 is restrained and can not rotate.Middle presser foot 18 is more slightly longer than side pressure pin 16, middle presser foot is faster contacted Connect the copper sheet of ground wire.When dropout main shaft is rotated to pressed status, dropout spring savings potential energy, once the constraint of lock catch block 14 Release, dropout spring is to promote dropout main shaft to rotate to trip action to complete.
Reseting procedure after dropout is such:
After dropout, magnet coil dead electricity, magnetic force disappears, and iron mandrel 12 is in the presence of back-moving spring to the side of dropout main shaft 20 To putting in, locking bolt 15 is pressed on the outer face of chuck 22.The card of bottom claw 211 of reset key 21 is inserted in reset key connector 17 On, reset key connector 17, which has, gap in the middle of a pair of hook pin, hook pin, transverse axis of the hook pin for support claw 211, and claw 211 perpendicular pin is then inserted in the gap in the middle of hook pin.After trouble shooting, reset key is pressed, due to reset key and dropout main shaft The clamping of reset key connector 17, will rotate the opposite direction of dropout main shaft 20, the end of middle presser foot 18 and side pressure pin 16 is along arc Shape track is threaded to minimum point, moreover, wedge 221 slips over the wedge surface of locking bolt 15, the card of locking bolt 15 is inserted in wedge 221 and spacing Between block 222, and dropout main shaft 20 is prevented to continue to rotate by limited block 222, middle presser foot 18 is with side pressure pin 16 respectively by three Piece shell fragment 7 is pressed on contact.
The present invention by detecting remaining leakage current on ground wire and remaining drain voltage, when ground strip certain numerical value leakage current or During drain voltage, earth leakage protective device action, live wire, zero line, ground wire, three poles simultaneously switch off, play a part of effectively protecting.It is local When tape is electric, zero sequence current mutual inductor detects ground wire electrification, and contact is flicked.Or when ground strip voltage, zero-sequence current is mutual Sensor detects electrical leakage voltage, and contact is flicked, so as to play the protective effect to ground strip leakage current or ground strip drain voltage.Leakage After electrical protective device action, it is necessary to after user excludes drain conditions, by hand-reset, can recover the normal of the product makes With.
The socket of the present invention also has WIFI intelligent functions, and socket is led to by the serial ports of main program chip with WIFI module Letter, WIFI module by local WIFI and network link, and with mobile phone UNICOM, the equipment is controlled by cell phone intelligent, meanwhile, The specific works information of the equipment, in good time synchronous feedback can be given user mobile phone intelligence APP, user can be allowed to pass through cellphone information It has been shown that, as long as in the place for having mobile phone signal, the running situation of the equipment can be understood in good time, everywhere.Intelligent WIFI controls system System includes intelligent WIFI module, intelligent single-chip microcomputer, mobile phone A PP intelligent platforms, cloud service platform etc..Three pole leakage protection systems And the part function of intelligence WIFI control systems two is to be mutually related, when there is electric leakage action, intelligent control fails, it is necessary to arrange During except failure can only hand-reset can be continuing with.But meanwhile, it is any that intelligence control system can occur to the equipment in good time Failure feeds back to user by cell phone intelligent APP in good time, allows user's very first time to understand failure cause.
The earth leakage protective device of the present invention can be applied on change-over socket, can be applied in ordinary plug, common On socket, application is widely.
Above-mentioned specific embodiment is only the preferable embodiment of effect of the present invention, all identical or equivalent with this structure Earth leakage protective socket with intelligent control function, in the protection domain of the application.
