Explosion-proof electrodeless lamp is a new generation of high-tech lighting products integrating explosion-proof, protection, electronics, optoelectronics and vacuum technology. It is mainly used for lighting in drilling, oil production platforms, oil production equipment, oil refineries, chemical plants, steel, electric power, mining, etc.; and it can be applied to fixed lighting of land and offshore oil drilling machines and workover rigs with vibration operations.
The principle of illumination of explosion-proof electrodeless lamp, stepless mining lamp and stepless street lamp is: after inputting a certain range of voltage, the 2.65MHz high-frequency constant voltage generated by the high-frequency generator is sent to the power coupler, and the power coupler is in the discharge space of the glass bulb. A strong electrostatic field is established to ionize the atmosphere in the discharge space and generate strong ultraviolet light. The three primary color phosphors on the inner wall of the glass bulb are excited by strong ultraviolet light.
In the power supply design, due to the adoption of APFC power control technology and the use of IC technology, on the one hand, the power factor of the power supply is as high as 0.95 or more; on the other hand, the high-frequency generator is always lit with high-frequency constant voltage. Therefore, when the input power supply voltage fluctuates within a certain range, the luminance of the light does not change. The lighting frequency of the lighting is as high as 2.65MHz. For a long time, the stroboscopic problem of ordinary fluorescent lamps has been completely solved. Working and learning under this lighting, the human eye will not feel tired again! Therefore, the explosion-proof electrodeless lamp is a new generation of high-tech lighting source products with typical environmental protection, energy saving, health and unlimited application prospects.
At present, Woneng Technology Wuhan Co., Ltd. is committed to the research and development and production of new energy-saving products. It has passed the ISO9001 quality management system certification and has become a member of the Board of the China Explosion Protection Association. Explosion-proof electrodeless lamps, stepless mining lamps, stepless street lamps and other products are the new generation of energy-saving light sources developed by our company after years of scientific and technological public relations. They have obtained national patents and are declared to be the national “Eleventh Five-Year†scientific and technological research project. The first product of Green Lighting Project represents a new light source with long life, high luminous efficiency, high energy saving, high color rendering and future development. Reading era

Product introduction of temperature controller:
It is mainly composed of elastic element, sensing tube, temperature sensing component, electric heating element, integrated converter and digital display instrument. The temperature packet of the transformer winding thermometer is inserted into the oil hole on the top of the transformer oil tank. When the transformer load is zero, the reading of the winding thermometer is the temperature of the transformer oil; When the transformer is loaded, the current directly proportional to the load taken out through the transformer current transformer flows through the electric heating element embedded in the corrugated pipe after being adjusted by the converter, The displacement of the elastic element increases. Therefore, after the transformer is loaded, the displacement of the elastic element is determined by the top oil of the transformer and the load current of the transformer. The temperature indicated by the transformer winding thermometer is the sum of the transformer oil temperature and the temperature rise of the coil to the oil, reflecting the temperature of the hot part of the measured transformer coil.
