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.
