Walking on the street, you can often see green iron cabinets with the words "Beware of electricity, don't touch". This is the only way for transformers to flow into thousands of households. At present, Huizhou has a total of about 13,000 public transformers and more than 20,000 dedicated transformers, all of which have been connected to the “backstage†– metering automation system.
This system returns the transformer operation data to the metrology center database every 15 minutes, and monitors the "health" of the transformer in real time. Recently, Huizhou's system is connecting and integrating with the province's system, making it more convenient and easy to use.
Remote verification no longer runs
At the Measurement Center of Huizhou Power Supply Bureau, the User Measurement Assistant is responsible for Su Xianle to open the measurement automation system they are using now. This is their work platform, meter reading data, power load analysis, peak value management, line loss analysis, power quality... After each key, the corresponding user's power consumption data.
Click on the “meter inspection†in the system, select a special user number, and the user's voltage, current and active power will jump out. The lower half of the table is the "physical examination form" given by the system: the overall conclusion is qualified, the voltage check is √, the current check √, the measurement error check √...
Su Xianle said that a very important duty of the measurement center is to regularly give the special-purpose (special transformer) user calibration meter every year. According to the regulations, the categorical users of the first and second class will go to the site every six months and one year to check the list, and the watch will be inaccurate; the third and fourth class users will generally check once every two years.
Precision Polished Aspheric Lenses
Why choose aspheric lens?
Aspherical Lens is a single optical component with one or two aspheric surfaces. An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. As optical systems are pushed to be better, faster, and cheaper, it becomes necessary to explore aspheric solutions. Aspherical elements eliminate monochromatic aberrations (e.g. spherical aberration) and improve focusing and collimating accuracy. The whole system will be smaller and lighter, and possibly cheaper than the multi-lens design.
Our aspheric lenses are made by grinding & polishing.
