Recently, users reported that when they watched TV at noon one day, they heard that thunder was heard. They quickly turned off the TV. When they opened the TV and watched it at night, they found that the TV could not be turned on. This realized that the TV was being given by Ray. Hey!
The TV was turned off. Why was it broken by the Thunder? It turned out that when the user turned off the TV, he just turned off the TV with a remote control and did not unplug the power. In this state, the TV was still in a standby state, which means that it was also charged. At this time, once there is thunder and lightning, the thunder and lightning suddenly generate a huge current, and the current may enter the TV and the set-top box along the power line and the TV signal line, causing the television or the set-top box to be wounded. Lightning voltages are all in the tens of thousands of volts, and the operating voltage of the internal electronic components of televisions is mostly from several volts to several hundred volts, and the operating current is not large. The high voltage and high current generated by lightning will instantly cause the device to break short and even crack, causing damage to the TV.
Therefore, do not think that turning off the TV when thundering is a good thing. If you completely remove the power supply, you can effectively prevent lightning. Of course, in addition to television, lightning protection of other home appliances and digital products is also very important.
>>>>Air conditioning: outdoor unit attention to lightning protection
Air conditioning is one of the household electrical appliances that are most vulnerable to lightning strikes. Because the compressors for air-conditioning and refrigeration are often installed outdoors, they are vulnerable to direct lightning strikes and introduce lightning into the room to burn out the host. If the air conditioning is turned off during thunder, but the plug is not unplugged, the primary circuit of the power board will be damaged, that is, the rectification and filtering part; if the air conditioning is still running during the thunder, then the fault part may be more, the control circuit, CPU, power supply Some are possible and can even damage the compressor.
>>>> Solar water heater: it is best to install an independent lightning rod
Solar water heaters are installed outdoors, and are easy to ignite household electrical appliances. If the user is bathing or using water when thundering, it will cause the solar water heater and the human body in the highest point of the building to become a conductor and become a lightning protection device. Lightning hitting solar water heaters will endanger human life safety. The installation of a solar water heater on the roof requires the installation of a separate lightning rod, and in the case of thunder, it is best not to use a water heater to avoid and reduce the damage caused by lightning.
>>>> Computer: Unplug the network cable and power
When thunder and lightning occur, various types of metal pipes and wires that can easily enter buildings generate lightning electromagnetic pulses, which are called inductive lightnings. Inductive lightnings can easily enter the room through the network cable. In severe cases, the power supply or the motherboard is burnt out. Using the computer to access the Internet, the loss of the computer will be even greater. Therefore, the interior of the computer needs to be equipped with lightning protection devices, ie, shielding, grounding, and installing lightning arresters. Without these devices, it is not useful to turn off the device during thunder, and it is necessary to remove the plug.
>>>>Washing machine: pay attention to the water pipe
The circuit board of the automatic washing machine is a module-integrated microelectronic computer board, and the anti-lightning performance is relatively poor. Lightning strikes can easily cause a short circuit in the circuit board, causing the washing machine to be unable to use or even leak current. Another safety hazard for washing machines in thunderstorms comes from the water pipes, which also increases the probability of the machine being hit by a lightning strike. So when it is thunder, it is best to stop using the washing machine and remove the power outlet. When not in use, it is best not to connect the washing machine to the water pipe.
>>>> Mobile: It is best not to use when thunder
Whether the mobile phone is ignited, the industry has different views. One faction believes that when thunder and lightning weather occurs, a large amount of positive charges are accumulated in the clouds, and the ground generates a large amount of negative charges. The process of receiving signals by the mobile phone is to receive electromagnetic waves, which is equivalent to building a channel for the lightning into the ground and let the positive and negative charges Connected, it will instantly lead the mine. The other faction believes that mobile phones will not lead to lightning. The reason people who use mobile phones when thundering are struck by lightning is because their location is at a commanding height relative to the surrounding environment. No matter what the right view is, it can be determined that the mobile phone's magnetic field will certainly change when thunder strikes, so for safety reasons, it is best not to use mobile phones when thundering.
Dc Gear Motor can be defined as an extension of Dc Motor which already had its Insight details demystified here. A dc Gear Motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM .The gear assembly helps in increasing the torque and reducing the speed. Using the correct combination of gears in a dc gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction.
Application field: usually used Electronic door locks, shutter motor, home audio equipment, sweep the floor machine robot
Features: dc gear motor drive precision, small volume, large torque, low noise, durability, low energy consumption, customized power design,easy installation, easy maintenance;Simplify design and save space.
Method of use: the best stable in horizontal plane, installed on the dc gear motor output shaft parts, cannot use a hammer to knock,knock prone to press into the dc gear motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Dc geared motors should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Dc geared motors should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of dc gear motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
