Electrical switches (including circuit breakers, transfer switches and contactors) in the power supply network are usually used to close or disconnect the circuit that supplies electrical energy to achieve the purpose of power outage, power supply and conversion circuit. When abnormal conditions occur in the power grid, such as overload, overvoltage, undervoltage, short circuit, etc., the load can be automatically disconnected from the power grid. Because these abnormal conditions will endanger the safety of ope

Dielectric barrier strong ionization discharge technology is an important emerging aspect of plasma application technology. It covers a thin dielectric layer on both sides or one side of the gas discharge gap by using methods such as sticking. When a high-voltage alternating current of a certain frequency is applied between the two electrodes, the gas in the gap will be ionized, forming a strong The gas discharges, thereby creating a high concentration plasma. The discharge intensity of the gas in the gap is a quan

.i Heavy Ion Research Facility Overview The Heavy Ion Research Facility (HIRF) is a large plastic core physicist designed and built by my country. 3 Ripple ring Since the bridge port voltage has low-frequency ripples of 50Hz, 100Hz, and 150Hz, it is difficult to suppress c. It must be detected by frequency selection and negatively fed back to the voltage regulator to make the power supply ripple smaller and meet our requirements. Therefore, we choose a band-pass filter. The band-pass filter can pass the signal i

Benefiting from the strong demand for consumer electronics represented by mobile phones, electric vehicles, notebook computers, and digital products, the global lithium-ion battery industry has maintained a rapid growth trend in recent years. Lithium-ion batteries are mainly composed of four parts: positive electrode material, negative electrode material, electrolyte, and separator. Electrolyte is one of the key raw materials of lithium-ion batteries and the blood of lithium-ion batteries. Lithium hexafluorophos

On March 19th, the much-anticipated CIBF2021 my country International Battery Exhibition kicked off in Shenzhen. AVIC Lithium Battery's new generation of battery products and cutting-edge innovative technologies were unveiled, "consolidating products" to build a new energy ecology, and "innovative technologies" call for a better future. High energy density ternary battery system fire-free technology and product debut Safety is the bottom line and cornerstone of the new energy vehicle i

A few days ago, the "Second New Energy Vehicle and Power Lithium Battery (CIBF2021 Shenzhen) International Exchange Conference" was held in Shenzhen. At the special forum named "Soft Pack Battery Core Materials and Advanced Technology Breakthrough" named by Fengfan Co., Ltd., Guangzhou Automotive Mei Ao, a senior engineer of the Automotive Engineering Research Institute of the Group Co., Ltd., gave a speech on the theme of "New Materials Promote the Performance Improvement of Power Lithium

"Traditional automobiles belong to the manufacturing industry and show a linear increase; while smart electric vehicles belong to technology-based companies, their rise is exponential. Tesla in the United States, Weilai and Xiaopeng in my country are all like this." A few days ago, the "Second New Energy Vehicle and Power Lithium Battery (CIBF2021 Shenzhen) International Exchange Conference" was successfully held in Shenzhen. The theme of this conference is "Application and Development o

With the development of automobile technology, there are more and more on-board electronic facilities and entertainment facilities. These electronic systems increase the pressure on vehicle energy. Under normal circumstances, when the power consumption is 1kW, it consumes 0.7-1.2L per 100km. With the development of automobile technology, there are more and more on-board electronic facilities and entertainment facilities. On the one hand, these electronic systems increase the pressure on vehicle energy. Under nor

According to foreign media reports, the Pacific Northwest National Laboratory (PNNL) has developed a new battery electrolyte formula, which aims to extend the service life and battery capacity of the battery, thereby increasing the cruising range of electric vehicles. In a separate project, engineers at the University of Colorado (University of Colorado) are developing electric vehicle technology that will allow wireless charging while the vehicle is in motion. The new battery electrolyte can increase the servic
