In home decoration, consumers often attach great importance to the final decoration effect. However, when considering how to choose floor tiles and furniture, you have thought about the importance of electricity safety. The Chinese consumer home safety survey shows that there is concern about fire. Respondents in the explosion, hydropower safety accounted for nearly 40%, and the importance of electricity safety is self-evident. Renovation wiring design is very important A large number of residential electrical line fires have caused major economic losses and casualties to residents every year. With the continuous improvement of quality of life, low-standard electrical design has become a bottleneck restricting the improvement of quality of life. Due to the small number of fixed sockets designed for residential use, people often have to pick up the mobile socket board. According to a survey conducted by the International Copper Association (China), only 30% of the mobile socket boards sold in the Beijing market are qualified, and the mobile socket board is an important cause of fire accidents. Zhang Ren, secretary general of the China Building Decoration Association, told reporters that home decoration should fully consider safety, functionality and comfort in wiring design, and should meet the needs of life and long-term development. In the circuit wiring, we must carefully consider the number of sockets. If the number of sockets is too small, the residents have to add socket boards, which will cause unsafe hidden dangers. Therefore, the number of sockets should be considered in advance, and the use of mobile sockets should be minimized. possibility. Zhang Ren reminded consumers that before the renovation, consumers should communicate clearly with designers and electricians, understand the electricity load of the room, and tell the model, size, specifications and power of the appliance to make it reasonable. Design the circuit. When the renovation of the new home is completed, the home improvement company must be asked for the wiring diagram of the residential electrical appliance so that the residential circuit is well known. The bathroom must be equipotential bonding The environment of the bathroom is quite special. The distance between water and electricity is very close. If there is a slight carelessness, a safety accident may occur. In recent years, incidents involving electric shocks in the bathroom and causing personal injury or death have been reported frequently. Shen Zhenhai, secretary-general of the Beijing Interior Decoration Association, told reporters that the main cause of such electric shock accidents was the significant drop in resistance after the human body was wet. When the human body is dry, the body's resistance is relatively large, usually about 2000 ohms. If there are tens of volts of voltage passing through the human body, at most, it will only feel numb, and there will be no other problems. However, people are soaked in the shower, the body's resistance is greatly reduced, and may be only 100 to 200 ohms. At this time, even if the voltage applied to the bathroom along the metal pipe is only one or twenty volts, it is enough to cause ventricular fibrillation and death. Moreover, the bathroom is generally equipped with a bathtub or a wash basin, and the indoor environment is relatively humid, and there is a high possibility of an electric shock accident. So is there a device that can protect the safety of the occupants like a car's airbag? The answer is yes, that is the equipotential bonding. Shen Zhenhai said that the "House Design Code" promulgated in 2005 stipulated that the bathroom should be equipotential bonding, but this regulation is not a mandatory standard. In recent years, although developers have basically reserved equipotential boxes in residential design, many decoration companies and residents are not sure what the box is. In order to ensure the safety of electricity in the bathroom, the new "Dwelling Design Code" officially implemented from August 1, 2012 clearly stipulates that "the equipotential bonding should be carried out in the residential bathroom". The mandatory provisions of the new standard indicate the state's problem. Value. According to Shen Zhenhai, the equipotential bonding in the bathroom refers to the interconnection of various metal pipes in the bathroom, steel bars in the floor, protective lines entering the bathroom, and the outer casing of the electrical equipment with hot-dip galvanized flat steel or copper conductors. . Equipotential bonding in the bathroom allows the bathroom to be at the same potential, helping to reduce potential differences and prevent dangerous contact voltages. It can be seen that the equipotential is like the airbag of a car, and its importance cannot be ignored. Don't let the construction work leave the hidden danger The water circuit renovation is a small expenditure during the renovation, and this part of the increase is most common. Fang Jingxiang, customer service director of the industry's Fengfeng Decoration Group, told the reporter that the formal decoration company will issue a water circuit transformation plan before the renovation for the owner, and pre-buried the line to verify whether the water circuit transformation is reasonable, and finally use this as a basis. construction. However, many non-standard "guerrillas" or small companies can not only fail to design first, but also cut corners during the construction process, leaving consumers with many security risks. For example, some companies do not follow the prescribed construction when laying the wires for the convenience of the figure, but they are dragging and pulling. After a long time, it is easy to cause electric leakage and electric shock. In order to save money, some companies do not calculate the safe current carrying capacity when selecting the wire. What line is used for the cable, and there is no fuse protection. The wire has many connectors, so that if a short circuit occurs, it is easy to expand the accident and even cause a fire. Fang Jingxiang said that consumers should not be cheap when choosing the electrical line configuration. They must standardize the construction and choose good quality wires. The one-time investment is for decades of life safety. According to the reporter's understanding, the national regulations stipulate that the cross section of the copper wire in front of the meter should not be less than 10 square millimeters. The cross section of the copper wire of the general lighting and socket in the house should not be less than 2.5 square millimeters. The cross section of the copper wire for high power electrical appliances should be no less than 4 square meters. Millimeter.
