The kitchen socket is oily and stained because of the baptism of the oil smoke all the year round; the tow line is not cleaned for a long time, and it is covered with dirt; the long-term unused electrical plug is hanged freely, and it is covered with dust... Many people have this kind of long-term cleaning. The "unk-faced" plug and socket seems to have nothing to do with safety, but it is hidden. When the plug and socket are not used for a long time or are not cleaned, some dust and hair will gradually accumulate between the two poles of the plug and the socket jack. Once the dust and hair touch the moisture, it is likely to become a conductor and make the power supply. A loop occurs between the two poles to form a state of energization. This phenomenon of energization is called "contamination conduction." "Soil pollution" can cause poor contact of the circuit, and can cause local heat to be severe, which causes deformation of the insulating resin of the plug and the socket, which may cause a short circuit and cause a fire. According to statistics, in 2012, there were 46 electrical fires in Jiaxing City, of which 30 were electrical circuit failures and electrical equipment failures, accounting for 65% of the number of electrical fires, and a large part of them were caused by plugs and sockets. The fire department reminds the general public that in a dry environment, plugs and sockets should always be wiped clean with a dry cloth to prevent accumulation of dirt; in places with more moisture and fumes, such as bathrooms, toilets and kitchens, it is best to use waterproof The socket of the cover; regularly vacuum the dust in the tow board, or turn the tow board upside down, gently tap the bottom, and then wipe the dust off the surface with a dry cloth; when the long-term unused appliance is covered with a dust cover, Don't forget to cover the electrical plugs; the unused tow boards are best included in the cabinet, kept in a safe place to prevent dust accumulation; unplugged long-term plugs can save money and safety.
