A lot of people go in and out of the community, there is such a
experience: the electric expansion door open only one person size of the channel for people to pass, they have to be slightly sideways into the body, in fact, at this time, your practice is quite dangerous.
In recent years, there have been many cases of electric and telescopic doors being knocked down everywhere, some of them even killed by electric shocks. Speaking of the "killing power" of the electric telescopic door, it is really staggering.
Now the electric expansion gate, although the control voltage is only a dozen volts (such as 12 volts), but generally use a voltage of 220 volts, and the safety voltage of the human body is 36 volts. When people touch a voltage of 220 volts, they are very likely to be injured or even fatal.
So, why does the electric expansion gate leak? Experiments show that the leakage of electricity after repeated wear and tear of its moving wires. Once the conductor is creepage, and the material of the retractable door is stainless steel, it is a conductor. Therefore, the body will have the danger of being struck by electric shocks.
The most effective way to prevent electric telescopic door accidents is to enhance maintenance. Once the traverse is found to be worn, it will be replaced immediately. Secondly, a leakage protection device can be installed on the retractable door. If there is electricity leakage, it will automatically cut off the power supply.
It seems that in the future, when the unit is working overtime or returning to the District, it will see that the electric telescopic door only allows only one person to pass through. For the sake of their own safety, let the security guard open the door up a bit. Do not squeeze through the electric telescopic door, can not use life to joke!
