Principle of Power Extension Sockets

The circuit of the traction board is the zero line and live line of 220V AC. one more ground wire (yellow and green wire will be used in the wire) is connected between the zero line and live line with electrical appliances, so that the electrical appliances form a loop as a load. There is no key on such a trailing board. If a key is required, the power construction switch needs to be connected in series in the live line circuit. If an indicator light is required, it is generally an LED light connected in series, and a resistance of about 100k Ω is connected between the zero live wires.

Genaral Questions About Power Extension Sockets

How long can power extension sockets be used?

The service life of the normal patch panel is generally three to five years, but it is also determined according to the quality and the frequency of use. In case of aging such as damage, it needs to be replaced in time.

What are the advantages of fbele patch panel in flame retardant?

The fire resistance and flame retardancy of the material are improved. The flame retardancy of the shell requires that the new plastic material can automatically extinguish after contacting the external fire for 3 seconds at 750 ℃. If the electric kettle, electric heater and electric rice cooker are connected to the row plug at the same time, the total power is easy to approach or exceed the power design peak of the row plug. Some row and insert panels made of traditional ABS materials will melt due to high temperature, thus causing fire or more serious safety accidents. According to the standards of the new national standard, only by using PP or PC and other materials can the row plug pass the more strict open fire certification and prevent the occurrence of fire.

Does the power cord of the patch panel need to be further thickened?

The thickening of the wire reduces the resistance, thus reducing the heating of the wire, slowing down the aging of the power line and the problem of easily causing flame. You can check the text on the cable. The row plug for ordinary family use is the 5-meter cable 10A standard, that is, there must be 3 × 1 square millimeter mark.

Is the switch of patch panel important?

The switch is a necessary function of the patch panel. The patch panel was originally made of fuses. Since it was inconvenient to replace the fuses, it was later replaced with a recoverable switch. I think this function is very necessary. Once the line is short circuited, it can be protected at the first time. Because according to the national standard, the general switch is 10a, of course, it means that the total power of all the appliances on your patch panel cannot exceed 2200W. Don’t look down on this small switch. Nine times out of ten the patch panel is damaged because the switch is burnt and bonded. Therefore, try to select the patch panel with good switch workmanship. The rocker switch pressed left and right (most of the contacts are silver alloy) is far better than the button switch pressed up and down!

Is the patch panel safe?

The patch panel is not safe to connect with the patch panel, and there is a large potential safety hazard. When the total power of the electrical appliances connected on the patch panel exceeds the maximum power that the patch panel itself can bear, the patch panel will be extremely likely to heat and burn, resulting in line fire and indoor fire.

Do you want to disconnect the power supply when not in use?

Unplug the plug and disconnect the power supply in time. When the plug-in board is not needed, unplug the plug and disconnect the power supply in time. If the plug-in board is not intended to be used for a long time, it is recommended to store the plug-in board to ensure safety and prevent dust from polluting the plug-in board.

How to select a safe patch panel and what problems should be paid attention to?

The current patch panels are all smart patch panels. As long as you choose the right brand, the safety can be basically guaranteed. Don’t worry. For example, fbele is an intelligent patch panel with excellent quality. If you don’t pay attention to them, it is difficult to realize their differences. However, in fact, fbele products are much better than bulls in design, quality and appearance.
