The patch panel is safe to useIssuing time:2018-04-28 18:17 The patch panel is widely used in every corner of life work, but the small patch panel is convenient for us to live, but also brings a lot of fire hazards to our lives. How can we prevent the fire caused by the patch panel? Poke map learning, forwarding diffusion ~ The widespread use of household appliances has directly led to the popularity of patch panels, but the correct use of patch panels has often been overlooked. According to the survey data of the public security department, the fires caused by the short circuit of the power strips, switches and circuit breakers in China from 2004 to 2017 accounted for almost 30% of the total number of fires in these years. Therefore, the correct use of the power strips cannot be ignored. Mistakes should be avoided when using the power strip 1. The position of the patch panel is too low Many homes feel too high and unsightly when installing the patch panel, and they will be installed in a lower concealed position. However, Dr. Xia Dong of the Institute of Electrical Engineering of the Chinese Academy of Sciences said that it is easy to cause water to splash into the patch panel when mopping the floor, resulting in leakage accidents. According to the industry regulations, the wall-mounted patch panels should be no less than 1.8 meters from the ground; the concealed patch panels should not be less than 0.3 meters from the ground. The kitchen and bathroom wiring boards should be more than 1.5 meters above the ground, and the air conditioning power strips should be at least 2 meters. 2, the plug-in board wire is installed freely The copper wire cross section must be used for the power leads. If you live in an old house, be sure to replace the original aluminum wire with a copper wire. Because the aluminum wire is easily oxidized, the joint is easy to catch fire. There have been surveys showing that the incidence of electrical fires in residential buildings using aluminum wires is several times that of copper wires. In addition, many families use the method of slotted and buried pipes for aesthetics. Xia Dong reminds that the wiring must follow the principle of “fire line into the switch, zero line into the lamp head”, and also set on the power strip. Leakage protection device. |
