With the development of IoT and 5G technology, the era of intelligent sensing and interconnection has arrived. Smart sensors are the front-end equipment of smart sensing and are the only way for China’s industry to “grow from large to strong”. Smart sensors refer to sensors that combine sensors with microprocessors and have signal monitoring and…
The high sealing of modern residences makes life more comfortable, private and energy-saving, but carbon dioxide and water vapor produced by human breathing; formaldehyde and MOM produced by building materials, furniture, curtains, etc.; dust produced by clothes and bedding; human body, The odors generated by smoking and cooking will accumulate indoors. If you open windows…
In recent years, my country has been vigorously adjusting its energy structure, and many cities have gradually replaced coal with clean and environmentally friendly natural gas to improve environmental pollution problems. With the continuous expansion of cities and the increase in population density, the emergence of county-level cities has also promoted the reconstruction and expansion…
The current global energy situation is becoming increasingly tense, and the development of the new energy industry has become an inevitable trend. As an emerging industry in the field of new energy, energy storage has already established energy storage power stations in some areas, which can improve the distribution network ‘s ability to accept distributed…
Sulfur dioxide (SO2) is a toxic and harmful gas with a pungent odor and hygroscopicity. It is an easily oxidized substance and can be oxidized by oxygen, nitric acid and other compounds into substances such as sulfuric acid (H2SO4) and sulfuric acid dioxide (SO3). SO2 is a colored gas at room temperature, with a higher…
With the continuous development of society and the gradual improvement of people’s living standards, the public ‘s demands for safety, health and environmental protection have become increasingly strong. Among many fields, the demand for accurate detection of low-concentration acetone gas is particularly prominent. At this point, the advantages of oxide semiconductors are obvious. Due to its characteristics such as high…
Burning two new motors in a row ! The output current and voltage of the inverter are balanced, and the input voltage is balanced. The current is unstable and fluctuates between 20% and 50%. The inverter burned out due to a short circuit between turns at 35Hz. The grid voltage is very stable, 720V. The…
Frequency converter , as the name suggests, is a device that can change the frequency. It is an AC power supply whose frequency and voltage can be adjusted to output . It is mainly used to regulate the speed of asynchronous motors . Before the advent of frequency converters, speed regulation of asynchronous motors was very troublesome because the speed and torque were not…
