Article studied asynchronous motor phased light load regulator of the principle of energy saving voltage regulator from the theory, impact of power efficiency of three key factors when the light load: Voltage, slip and power factor, proposed power-saving conditions. Running from the energy savings of view, in theory set up the ideas of the smallest energy consumption optimization target power factor...
The electrical tree discharge channel will be formed at concentrate of electric field in solid insulation dielectric, in order to study the difference of electrical tree under different electrical field, the short-cable electrode system with actual XLPE cable was designed, experiments were performed under 12 kV, 15 kV, 18 kV, 21 kV compare to the needle-plate electrode system. Experiment results show...
A new solid substrate-room temperature phosphorescence quenching method for the determination of trace copper has been established. It is based on the fact that beryllon (R) can emit strong and stable solid substrate-room temperature phosphorescence on the filter paper, and Vitamin C (Vc) reduces R to non-phosphorescent compound that leads to solid substrate-room temperature phosphorescence (SS-RTP)...
