Which socket is safe? What is the new national standard?

The country's 38 consumer rights units to remind: million hole socket, two-core socket are not safe what kind of socket security is a new national standard?

The new national standard of the socket is issued by the AQSIQ and the China National Standardization Management Committee on June 1, 2010 and is enforced on June 1, 2011. "New national standard" also provides that from June 1, 2011 onwards, office, home commonly used million hole power converter forced to prohibit the sale. Socket new national standard has been implemented for nearly 4 years, but the market is still very few new national standard socket, which triggered around the business sector concerns.

May 6, the national 38 consumer rights units jointly issued consumer warning: non-national standard power outlet unsafe, consumers at the time of purchase, be sure to buy a new national standard socket, do not buy unsafe million hole socket and two-core socket The

"New national standard" socket implementation, so that many people suddenly some Mongolia: "for many years the socket, turned out to be substandard products.

The face of the market on the dazzling array of the socket, the price is uneven, there are a lot of people do not know, what is the new national standard? Reporters decided to use a few simple experiments, with you to understand the new national standard socket and non-national standard socket difference.

Appearance identification

Recently, the reporter went to a farm market in Changchun City, even the seller did not know "new national standard." Reporters purchased five sockets, including non-national standard million hole socket and two-core socket, there are standards of "new national standard" socket.

Identification of the line board: the new national standard socket: five-hole design, three-pole jack and the two pole plug is separated, in which the three-pole jack has two holes are inclined non-GB socket three-pole jack are large round , This jack can be inserted into the three-pole plug can also plug the pole plug.

Identify the plug: the new national standard socket: plug is three-phase; non-national standard socket: plug is not uniform, and some even if the board is a three-pole jack, its plug may also be two-phase, there may be three-phase. In the four kinds of sockets, there is a substandard product, the appearance of the socket is a new design of the five-hole standard, can be plugged out of its non-national identity, its plug is two-phase, not in line with the new National standard. Electric Zhang master introduction, this is fake new national standard, generally pay attention to the jack, while ignoring the plug.

Internal identification

Remove one of the four sockets from inside.

New national standard socket: the internal three lines are zero line (black or green), FireWire (red), protective grounding wire (yellow and green).

Non-national standard socket: an internal also has three lines, but the core is very thin another internal two lines, one for the FireWire, one for the zero line.

Conclusion: Master Zhang said that unqualified non-national standard socket, many of the internal are only two lines, is less a protective grounding wire, and this line is very important, the line called "lifeline", in addition, the core Too fine also exist security risks.

Experiment 1: Measuring temperature

"Universal socket" metal plate "high fever"

Experimental preparation: the new national standard socket, non-national standard million hole socket, drinking fountains

Experimental steps: the new national standard socket and non-national standard million hole socket, respectively, set the drinking fountains, the time are half an hour, because the water dispenser for the three-phase jack, the use of three-phase jack.

Experimental process: Before the experiment, the reporter with a thermometer to align the metal plate within the socket made a temperature measurement, two socket three-phase jack within the metal plate temperature is 23 ℃.

Respectively, after 30 minutes with a water dispenser to measure the temperature results: the new national standard socket internal metal plate temperature of 23.4 ℃, the temperature rose only 0.4 ℃; non-national standard hole hole inside the metal plate temperature of 25.6 ℃, the temperature rose 2.6 ℃ The

Experimental results: data show that non-GB socket than the new national standard outlet temperature is higher, that is, the contact film overheating, more likely to lead to the occurrence of fire.

Experiment 2: Safety

Safe and unsafe in the "lifeline"

Experimental preparation: a power of 800 watts of drinking fountains, the new national standard socket, non-national standard two-core socket,

Experimental process: After master Zhang treatment, the water dispenser caused by leakage of the machine in the assumption that the case without knowledge, respectively, the use of the new national standard socket and non-national standard two-core socket for normal use.

Experimental results: non-GB two-core socket: plug in the water dispenser, the master with a pen to test the external water dispenser, electric pen light up, Master Zhang said that this shows that the water dispenser, in use, non-national standard Socket does not protect the ground wire, so the machine leakage, if you do not know, after touch is easy to electricity to people, it will happen electric shock response.

New national standard socket: plug in the water dispenser, I saw the fire flash, electrical open switch automatically trip principle analysis:

Two-core socket from the shape easier to distinguish, all the plug on the three-pole jack, but the socket itself comes with only two plugs on the plug, are two-core problem socket. This type of socket is missing a ground wire, in the course of use, once the electrical parts of an electrical insulation within the damaged, the current will be covered with the entire electrical surface, because the current can not be imported through the two-core socket underground, easily lead to electric shock.

The new national standard qualified socket, the internal protection of the ground wire, in case of leakage, the current can be safely into the ground, the general will cause the home box empty jump box power, can effectively protect the personal safety.

■ Optional

Optimistic about the production date and production standards

How can we buy a new national standard socket? Changchun City, a brand outlet agent Ms. Zhou introduced several simple ways to identify the advantages and disadvantages of the socket.

1. Recommended to the regular business super, electrical city to buy.

2. Look at the appearance: some unqualified socket packaging simple, the lack of the most basic manufacturers and product information, especially the product packaging on the production date, more low-quality socket product packaging is not marked on the production date, which often belong to substandard socket; Out of the million hole socket are marked "according to GB2099.3-1997 standard production" words, in line with the new national standard products marked on the packaging "according to GB2099.3-2008 standard production" words; qualified socket shell panel Fine workmanship, shell and jack side without burrs, jack size symmetrical uniform, poor quality socket shell rough work.

3. Look at the price: a good product prices must be relatively high, Ms. Zhou said that the agent of this brand the cheapest also 16 yuan, the most expensive to hundreds of dollars.

4. on the hole: million hole socket three-phase jack and two-phase jack is combined together, a total of three holes; and the new national standard three-phase and two-phase is separate, there are five holes seen After the board hole, but also look at the latch. Do not buy a three-pole socket on the card, but the socket itself comes with a two-pin socket with only two pins.

Glossary

"New national standard" socket: two-pole and three-pole jack separate combination form (commonly known as the new five-hole socket) socket, the board has a three-pole jack, socket itself comes with the same plug on the three plugs, Line connection.

Non-national standard socket: one is often said that the "universal socket" for a variety of electrical plugs, including flat, round, triangle, etc., three, two plugs can plug; the other is a two-core socket, although Some of the sockets of the socket have three-pole jack, but the socket itself comes with only two plugs on the plug, that is, "two-core card."
