Outlet has always played a minor role in our lives. Although they are almost ubiquitous, although television, computers, refrigerators, etc., are the words of the word “electricityâ€, they all have to be “hand-in-hand†with them, but it seems that people have already turned a blind eye to it and they have never thought about it. Small outlets will give up what moves. However, recently, the State Bureau of Technical Supervision conducted a quality supervision and inspection of plug and socket products, but it has since tightened the string of safe use of the socket.
In the first quarter of 1999, the State Bureau of Quality and Technical Supervision organized the National Day-use Electrical Appliance Quality Supervision and Inspection Center to carry out national supervision and spot checks on the quality of home appliances and similar plugs and sockets. The main checks were made in major cities such as Beijing, Shanghai, Tianjin, Guangdong and Zhejiang. 36 types of plugs, sockets, and converters for 34 companies in the city? Commonly known as patch panel? The quality, pass rate only accounts for 30%! The unqualified projects focus on important safety indicators such as protection against electric shock and temperature rise, resulting in great hidden dangers. Associating with a series of electrical fires that occurred in recent years, people can not help but be alarmed by a cold sweat. From the results of this random inspection, the plug and socket products produced by large and medium-sized enterprises are of good quality.
The products of the two large-scale enterprises that have been spot-checked are all qualified, and the qualified rate of sampling has reached 100%; the products of 10 medium-sized enterprises have been sampled, and 8 kinds of qualified products have been sampled; the passing rate of spot checks has been 80%; and the samples of 24 small-scale enterprises have been sampled. Products, qualified 13 kinds, sampling pass rate of 54.2%. The passing rate of product inspection for large and medium-sized enterprises is obviously higher than that of small enterprises. The spot checks exposed many problems with converter products. After the GB2099.1-1996 standard was implemented, many mobile outlets and converter manufacturers failed to organize production according to the new standards. In addition, there are also individual companies with weak technical capabilities, excessive production in the production process, and cutting corners. The copper strips used for the bushings are so thin that even when the temperature rise test is conducted, the wires and the copper sheets generate heat so severe that the temperature rise is too high. This kind of product has a hidden danger of causing fire.
According to statistics from the public security department, in the fire accidents that occurred in China in the past ten years, fires caused by electrical faults such as short circuit, overload, and poor contact have been the top of all types of fires, accounting for about 28% of the total number of fires per year. In the year 1997, there were 22,719 electrical fires across the country! Therefore, the elimination of fire hazards from the socket link has become increasingly important. Experts believe that in order to fundamentally solve this problem, it is necessary to "requirements" the material of the socket housing. To prevent electric shock hazards, the outer shell material of the socket is not allowed to use metal materials, and the insulating material should meet the best requirements for flame retardant. Case of fire does not burn? , the cost of its raw materials will increase 4-5 times! This will give a heavy blow to companies that originally used this huge difference to achieve low-cost occupation of the market. In addition, China's annual lightning strikes are relatively frequent. Experts have called for: The public's awareness of lightning protection needs to be improved. If necessary, outlet products with lightning protection can be used.
Modern electrical products create an ancient living space for fast-paced modern people, and outlets are an indispensable detail that embellishes this space. At present, the quality of plug and socket products that circulate on the market varies greatly. To address the existing problems, the State Bureau of Quality and Technical Supervision will cooperate with the enforcement of the new national standard and strengthen the publicity work on the national standards for socket plugs. Please pay attention to the following questions when purchasing:
1. The appearance of the product identifies the new national standard which specifies the rated current and is divided into three levels: 6A, 10A and 16A. Non-standard products such as 13A and 15A are not allowed to be listed on the market, and they are not allowed to be marked with 10A and 16A at the same time. phenomenon. In addition, when consumers choose the outlet, they should also check whether the plug and outlet are the same. If the rated current of the plug is less than the number of the outlet, do not buy it. This is a dangerous product that is not qualified. Another point, the product packaging must have a detailed manufacturer address, telephone number, only the mobile phone number or no site, counterfeit production licenses and electrical certification, 9000 certificates are three products.
2. Whether there is mis-insertion in the jack, the general plug-in is too close to the wrong insertion; the second is the unreasonable design of the multi-use jack itself, there is a tripod mis-insertion problem.
3. The material of the socket product is the internal connection of the socket, and the plug sleeve should be made of material that meets the specifications. If the internal grounding wire is too thin or the inserting sleeve is too thin, the temperature rise will be too high, causing fire; the second is the housing The use of flame-retardant enclosures prevents fire hazards from inside to outside.
In addition, relevant experts reminded consumers that when purchasing plug and socket products, they should also pay attention to whether the product has a production license or “CCEE†safety certification mark, and try to buy large and medium-sized enterprises' products as much as possible. price.
