Application:
CNZQ1 automatic transfer switch is suitable for two-path power supply system with AC 50 HZ/60HZ, rated working voltage 400V, rated current from 6A ~ 800A. It can automatically transfer power supply to reserve power or generator when common power occurring fault so as to guarantee the reliability and safe of supply power. MQ1 has the protective function of overload, under-voltage, short circuit and lack phase which is especially suitable for using in the place where does not allow power supply failure, such as fire fighting, hospital, marketplace, military project, high-rise building, bank, TV station and so on.

Fresnel lenses, also known as threaded lenses, are mostly thin sheets made of polyolefin material, or glass. One side of the lens is smooth, and the other side is engraved with concentric circles from small to large. Its texture It is designed according to the interference of light and the requirements of relative sensitivity and receiving angle.
The use of ordinary convex lenses will darken and blur the corners and corners. This is because the refraction of light only occurs at the interface of the medium. The convex lens sheet is thicker, and the part where the light travels straight in the glass will attenuate the light. If it is possible to remove the linear propagation part and only keep the refracted curved surface, a large amount of material can be saved while achieving the same light-gathering effect. The Fresnel lens uses this principle. The Fresnel lens looks like a piece of glass with countless concentric circles (ie Fresnel zone), but it can achieve the effect of a convex lens. If the projected light source is parallel light, the brightness of the image can be kept consistent after converging and projecting. .
Fresnel lens is equivalent to infrared and visible light convex lens in many cases, the effect is better, but the cost is much lower than ordinary convex lens. It is mostly used in occasions where accuracy is not very high, such as slide projectors, film magnifiers, infrared detectors, etc.
The Fresnel lens has two functions: one is focusing, that is, the pyro-infrared signal is refracted (reflected) on the PIR, and the second is to divide the detection area into several bright and dark areas, so that it can enter the detection area A moving object can produce a changing pyro-infrared signal on the PIR in the form of a temperature change.
