Switchgear handcart,shell, baffle and pressure relief device

图片
  Switchgear  shell, baffle and pressure relief device The shell and baffle of the  switchgear  are assembled by high-strength bolts (or rivets) after being processed and bent by CNC machine tools with anti-oxidation and anti-corrosion aluminum-zinc plates. Therefore, the assembled switchgear can ensure the uniformity on the size and high mechanical strength. The door surface paint of switchgear adopts polyester epoxy powder, which has the characteristics of impact resistance and corrosion resistance, and can Keep the appearance beautiful. On the top of the switchgear, the pressure relief device is installed above the circuit breaker room, bus room and cable room. In the event of an internal fault arc, the pressure inside the switch cabinet will rise with the occurrence of the arc, and the pressure release metal plate installed on the top will be automatically opened to release pressure and discharge gas directionally. The special sealing ring installed on the door w...

That’s Why You Need Nanocrystalline and Amorphous Cores for Components

图片
  That’s Why You Need Nanocrystalline and Amorphous Cores for Components Amorphous and nanocrystalline materials , as modern soft magnetic materials, are increasingly used in the production and research and development of CMC. After long-term optimization and testing, SAT Amorphous, as a leading supplier of magnetic cores in the industry, has designed and developed a series of high-quality related products for ABB, SE and other companies. It has made outstanding contributions to improve product performance. Common Mode Choke The nanocrystalline core has a high magnetic permeability in the low frequency to high frequency range. They are very suitable for common mode chokes as EMC filters to compress conducted common mode noise. Compared with traditional ferrite cores, nanocrystalline cores have many advantages, such as high inductance, good filtering effect, small size and volume, lower copper turns, lower power consumption, and higher efficiency. The Curie temperature of the nanocr...

Take you to understand the thermostat in one minute

图片
  Someone asked whether the floor heating can control the temperature like an air conditioner before, but now fewer people ask. It is estimated that there are more people enjoying floor heating and more people knowing about floor heating. In fact, floor heating can well control the temperature of each room thanks to the thermostat. First.  About floor heating thermostat The  floor heating thermostat , as the name suggests, is a device that controls the temperature of the floor heating. It can set the switch or adjust the room temperature in time according to people's needs, thereby achieving intelligent heating. 1. Composition Temperature control panel, temperature control probe, control wire, electric heating actuator, switch bottom box, wire tube. 2. Principle Floor heating thermostats are mainly divided into two types, mechanical and electronic. Mechanical type : A temperature control switch that uses a sensitive gas diaphragm or a temperature sensing element to form a...

What is the working principle of induction cooker?

  Induction cooker as a common electrical appliances, in the kitchen appliances occupy an important position. Induction cooker has a variety of different functions, such as cooking, beating hot pot, frying, cooking and so on, very convenient to use. Before buying electromagnetism furnace, it is necessary to understand the component part of electromagnetism furnace and working principle. If the induction cooker appears small fault, oneself can solve easily. Induction cooker is mainly composed of coil disk,   main control circuit board , fan, key display panel, ceramic panel, upper and lower shell, etc. How does an induction cooker work? The working principle is as follows: the surface of the induction cooker is a heat-resistant ceramic plate, alternating current through the coil under the ceramic plate to generate a magnetic field. When magnetic lines of force in the magnetic field pass through the bottom of an iron or stainless steel pot, vortices will be generated, which will...

Nanocrystalline Material Applications 2020

  Nanocrystalline Materials Applications in 2020 Because nanocrystalline materials have exclusive, favorable physical, chemical and mechanical properties,  they can be used in applications below. High sensitivity sensor High-sensitivity sensors  use their sensitivity to accurately detect changes in different parameters. Basically the parameters include chemical activity, thermal conductivity, resistivity of components, permeability of magnetic core and magnetic ring and capacity. All these parameters largely depend on the materials used in the sensor. The physical, chemical or mechanical properties of sensor materials reveal changes in the sensor environment, and these properties can be used for detection. It is known through experiments that reducing the grain size can greatly increase the rate and extent of the reaction. Therefore, sensors made of nanocrystalline materials are highly sensitive to changes in the environment. Common applications for sensors made of nanocr...

Why We Choose Amorphous Transformer in 2020

图片
  Why We Choose Amorphous Metal Transformer in 2020 In the past few decades, the environmental issues are not as prominent as they are today, so people did not pay as much attention to global warming and greenhouse gas emissions as they are now. Therefore, in the design of transformers, matters related to energy efficiency are not the first to consider. In the last ten years, in the power industry and all places related to energy conversion, ‘energy efficiency’ has been mentioned more and more, and it has also become the first consideration in the design and development of related equipment, such as electricity transformers and other equipment indispensable in the field. Transformer manufacturers used silicon steel sheets or ferrite as the main materials for their magnetic cores, but now more and more manufacturers choose to use  amorphous  cores  (a kind of soft magnetic material) as alternatives. As the world's leading manufacturer of amorphous and nanocrystalline ...

Better Audio Experience with BelFone Noise Cancellation Radios

  People living in the modern world are no strangers to noise. We are so used to the hustle and bustle of city life that we have all become quite tolerant of noise. However, when the noise of an environment reaches a certain level, it can result in serious challenges both to our health and to our work. Social workers have talked much and more about the health problems caused by noise. As a leading professional PMR solution-provider with more than 30 years’ experience and expertise in the field of radio communication, we want to talk about the communication challenges of a noisy environment and what we can do to help. When the noise level of an environment reaches beyond a certain point, you will have a hard time perceiving important stimuli in the environment, like people talking to you, or your attention is drawn away from these important stimuli by other acoustic signals. In such an environment, if you want to communicate with someone, you will have to raise your voice and yell. ...
