First, is the socket with leakage protector good?
1, leakage protector is a kind of relay protection device, used to prevent electric shock caused by leakage. Mainly installed in the switch socket, which can quickly disconnect the leakage switch socket.
2. Because the currents of the neutral line and the live line are equal, the current from the power supply will reach the live line through the neutral line. When household appliances leak electricity, the charged current is taken away by the grounding wire, so the current between the two wires is different. At this time, the leakage protector will generate induced voltage, which will trip the switch immediately to prevent people from getting an electric shock.
2. What type of socket is it?
1, single-phase two-hole socket
Single-phase two-hole wiring is very simple, just connect the zero line and live line of the socket to the zero line and live line of the power supply respectively.
2, single-phase three hole socket
Three hole socket's wiring is similar to a two-hole socket. On the basis of two-hole wiring, the upper jack can be connected to the power ground.
3. Three-phase four-hole and three-phase five-hole sockets
Both sockets have grounding ports, and the connection mode is to connect the zero line, live wire and ground wire of the socket to the zero line, live wire and ground wire of the power supply respectively. It should be noted that the phase sequence of the whole room must be consistent. In order to better distinguish, different colors of wires can be used to represent zero line, live line and ground line.
4. There is a special protective grounding socket.
This kind of socket can be put into use automatically after being connected to the power supply, and will automatically cut off the power supply after being cut off. This kind of socket must ensure that every pin is properly inserted during use, otherwise it will easily lead to safety accidents, so it must be used with special care.
Step 5 repair the socket
We use many fixed sockets. When carrying out hydropower projects, we will install switch sockets according to household electricity consumption. This socket is just a mobile socket.
6, mobile phone socket
Movable socket consists of flexible cord and independent socket, which can be used in some places where fixed socket cannot be installed. This kind of socket is very convenient to use and can be put away when not in use.
Third, the principle of leakage protector
1, when the line is overloaded, the "overload current" causes the "hot bimetal" to heat and bend, which pushes the "lever" to reset the "mechanical locking mechanism" and the "moving contact" quickly separates from the "static contact", thus realizing the disconnection function;
2. When the line has a "short circuit" fault, the "short circuit current" makes the "instantaneous trip" act, and the iron core ejector rod pushes the lever to reset the locking mechanism, thus realizing the breaking function;
3. When there is a "residual current" (leakage) or "electric shock" fault in the line, the signal output by the "zero sequence transformer" triggers the thyristor to turn on, so that the residual current operated circuit breaker can cut off the power supply in a very short time, thus realizing the residual current protection function.
The above is all the contents of the leakage protector introduced by Bian Xiao. I hope everyone can decorate the decoration effect they want.
