After the end of the refrigerator start, the set-top box signal will be broken, the TV image at the same time, and immediately there will be another image, how to solve? TenThe refrigerator is also a year long, in turn the refrigerator temperature regulator, signal set-top box will not me, I put the refrigerator for a socket all right, previous estimates is a line, not now, but after the change of the refrigerator power line influence people to walk, in the foundation a line on how to solve the problem how to solve?Some people say that this is a power grid harmonic interference problems, using metal paper or metal pieces to block the influence of the magnetic field of set-top boxes can, or buy a filter socket.It is also said that the voltage problem.What the hell is going on?
Related to the line, other people's home appliances are not the caseThe fridge is PTC soft start
Set top box is DC work, AC rectifier after what harmonic interference?Don't set-top boxes even have this anti-interference capability? If this is the case, then you can disturb your cell phone at home. Is there any interference?The main thing is that the regulated power supply in the machine doesn't work under the low voltage condition. (the power supply has an upper and lower limit, more or less will stop working, otherwise it will be harmful to the machine.). Your set-top box doesn't work within the voltage range of 110---220V, so you can see how the nameplate is written on the back of the box.
The starting current of the refrigerator is large, which causes the voltage in the circuit to decrease, and the voltage is reduced, so that the work of the set-top box can not be carried out, and the power is in the state of losing power,When the refrigerator starts to finish, the voltage in the circuit is restored to normal again, so that the work of the set-top box is called, so that the work can be done normally,The solution is two routes. If the lines affect walking, then change the wires in the line to another gearIn addition, the current increases, the voltage drop, and you use metal paper or metal plate to block the magnetic field of the set-top box is irrelevant, useless. Buy a filter socket is useless
This is called surge in the professional, is spread with the power line, you can not solve the problem with any package.From another point of view, the quality of this set-top box is not good!It is not the solution, there is the above said socket, with a filter or regulator, UPS, and so can you, or directly from the point of the knife cloth thick line to try, but I feel a little effect.In fact, if you understand the point, this solution is more simple, directly disassemble the set-top box, from the 5 volt power out of the position to it, and a larger than 4700 micro method of capacitance on it.
