This scam is the originator of such scams. It has been around since the 1980s, and the country has changed many times from Nigeria, and mail has changed from English to Chinese and other languages. For this reason, the Nigerian government had to show that the government did not exist in the form of such mail sent around the world. But it is still popular today, because there are still people who believe it.
In this sense, a liar is also wise. He does not need all of them to be deceived, as long as one person in the vast sea believes that cheating money into his hands is a success. It's like the security system in a smart home, so many times the alarm, but only a few times is true.
The security system in smart homes has always been favored by consumers, but alarm information has always been annoying. Let’s say we use infrared sensors that we can sense. The alarm may be reported many times, but only a few alarms are accurate. This is where many users are unsatisfied. Usually there is nothing to do on the police once, it is really a headache. Since users are in a headache, why can't businesses improve?
Due to the limited level of the alarm itself, the alarm is sometimes inconsistent. Do not report at the time of the alarm. Do not report the alarm when you are alarmed, for fear that you do not know. Unexpected accidents do not happen often, so more often infrared intrusion detectors are often in the event of nothing when the ring, no accidents, the alarm has been ringing, although more disturbing, can be little loss. However, if the sensitivity of the alarm is adjusted higher, when an accident occurs, the alarm may not be able to sound in time. This will result in property damage and even life-threatening. Weighing the pros and cons, we can only make the alarm more alarms. Times, just in case.
Sensitivity is lower, silly, and there is no harm in it. There must be one correct number of times. Although the current smart home fire, but its level of development is still limited, more human control, environmental induction is not enough. Looking at the smart home market, there are many smart home products in the security system, and the prices are also uneven, and you want to experience the smart home life, the wave package series of things sensing can be considered, of course, the most important reason is Is: The price is too cheap!
product description
GFDD series of top-blow dry-type transformers with cross-flow cooling fan (hereinafter referred to as: dry-type cross-flow cooling fan) is mainly used for dry-type transformers cooling capacity, and electronic equipment, power distribution cabinets, high and low voltage switchgear forced air cooling . Dry-type transformers coupled with the fan cooling, 40 ~ 50% capacity increase can be run, thereby greatly increasing the carrying capacity of dry-type transformers and prolong the service life of dry-type transformers, is widely used by domestic and foreign manufacturers the most cost-effective the way.
The product strictly according to JB / T8971-1999 "dry-type transformers with cross-flow cooling fan" design and production of motor set, the rotor core using high-quality cold-rolled silicon steel; low noise bearings; impeller using aluminum alloy surface electrophoresis, and then through the fine Dynamic balance adjustment; left and right end plate made of stainless steel stamping, into the wind board, the wind board and the wind deflector aluminum alloy buckle combination; the entire fan structure is reasonable, handsome in appearance, with air volume, noise, temperature rise Low, long life, stable operation, easy installation and so on.
working principle:
The series of cooling fan for dry-type transformers, fans placed on both sides of the lower part of the transformer coil, the wind blowing directly into the transformer coil high and low pressure cooling air duct, cooling effect is obvious, can protect the normal operation of the transformer and extend its service life (Fan open, stop and over-temperature alarm transformer, over-temperature trip and other functions have temperature control device to provide).
