Recently, Xiangtan Power Supply Company found that the dust-proof net entangled the wires in the double-circuit line. The staff quickly eliminated the hidden troubles on this line through the laser pointer and ensured the safe operation of the grid equipment.
The transmission and operation personnel of the State Grid Xiangtan Power Supply Company found that the 110 kV tea five-line #048-#049, 110 kV five-line #031-#032 double-circuit line in the same line Wrapped by the dust net. The air filter has shorted the double-circuit line wires. The situation is very critical. If it is not processed in time, the power grid equipment may be faulty. Due to the high distance between the conductor and the ground, the foreign matter has been short-circuited with double-return conductors. It is necessary to ensure safe and efficient elimination and no impact on power consumption. The conventional disposal methods such as power failure treatment, insulated arm car and operation rod can not eliminate hidden dangers. The laser removes foreign matter.
In the afternoon, the staff used the laser pointer to illuminate the appropriate energy laser beam onto the remote dust-proof net, and the dust-proof net was blown on the winding part of the transmission line, causing it to fall, and all the dust on the double-circuit line was dust-proof. The nets are blown and dropped, the hidden dangers of foreign objects are eliminated, and the transmission lines resume safe operation.
According to reports, the "laser cannon" has a range of 0-120 meters, the fastest time is 10 seconds, and the slowest is 20 minutes. The laser with specific power and band emission can effectively act on non-metallic materials in the grid, without being The metal material is absorbed by the line, so there is no damage to the grid equipment.
Laser beauty is to pass a laser beam of a specific wavelength through the epidermis and dermis, destroy pigment cells and pigment particles, and the fragments are absorbed by macrophages in the body, safely leaving no scars, and effectively achieving whitening.
In recent years, laser pointer beauty has been welcomed by people because of its painless, safe and reliable features. However, some people have doubts, if the skin is treated with laser or radio frequency equipment, will the stratum corneum be thinner?
Experts say that optoelectronic treatments produce thermal effects, and thermal effects reach a certain level, which can cause thermal damage. For example, high-energy treatment with non-stripping laser pointer can affect the stratum corneum of the skin. In the case of excluding excessive treatment, non-exfoliating laser low energy, LED, photon skin rejuvenation and other items, because of the weak energy, generally have no obvious effect on the stratum corneum. The degree of damage to the epidermis, the effect of non-exfoliation laser is greater than that of photorejuvenation, and the side effects of LED are relatively minimal.
