Wuhan UHV specializes in the production of series resonance, with a wide range of product selection and professional electrical testing. To find series resonance, choose Wuhan UHV.The necessity of conducting AC withstand voltage tests on high-voltage electrical equipment and the application of resonance boosting methods in power systems. In order to accurately determine whether electrical equipment meets operating conditions, prevent equipment damage, and ensure safe system operation, one effective measure is to conduct insulation withstand voltage tests on equipment. The insulation withstand voltage test includes two testing methods: DC withstand voltage and AC withstand voltage. The DC withstand voltage test is widely used due to its device's small capacity, small size, light weight, and easy portability. But not all electrical equipment can be explained through DC withstand voltage tests, such as rotor withstand v

What is the market sales volume of series resonance?
2025-11-11Series resonance (also known as series resonance withstand voltage device) has gradually entered people's field of vision and has been used in the detection of resistance voltage problems in factories. So, what is the sales volume of series resonance in the market now? What is the market sales volume of a product? It still needs to be analyzed from many different aspects.For example, in terms of its usability, if a product has low usability, it is believed that after being chosen by one customer, it will not be chosen by a second or third customer. However, series resonance has been increasingly used now because it can meet the needs of customers for equipment resistance and voltage detection. Moreover, the entire operation is simple and the data is accurate, which increases the value of the entire detection and can maintain the overall production efficiency of the factory.

Will there be data errors in series resonance?
2025-11-11Choosing series resonance is definitely to meet the battery voltage detection effect of the device, and to find a better solution to solve the problem. Therefore, it is necessary to ask whether there will be data errors in series resonance.The reason why buyers have such questions is also because they are worried that when using a series resonant device to test the equipment, if its overall detection effect is not particularly good, there may be corresponding errors that will lead to errors in the entire data analysis, and the selection of solutions to the problem will also bring great trouble, unable to solve the resistance and voltage problems of the equipment. But when people really choose series resonance, they will find that it has a very high level of safety in the measurement process, requires a very convenient way, and has particularly stable performance. These aspects determine that there will be no errors in the measurement of series resonance. If errors really occur, it is a

To find series resonance, choose Wuhan UHV.Analysis of the necessity of replacing DC withstand voltage with AC withstand voltageIn recent years, research results from many international and domestic research institutions have shown that DC withstand voltage testing is not suitable for testing cross-linked polyethylene cables. Some cables, even after passing the DC withstand voltage test, still experience insulation breakdown accidents shortly after being put into operation. The impact on insulation during the DC withstand voltage test is mainly manifested in:(1) DC voltage has an accumulation effect on cross-linked polyethylene insulation, known as "memory". Once a cable has "memory" caused by DC testing, the residual DC charges in the cable need a long time to be released. When the cable is put into operation, the DC

Variable frequency series resonant reactor
2025-11-10Variable frequency series resonant reactor? Wuhan UHV specializes in the production of series resonance, with a wide range of product selection and professional electrical testing. To find series resonance, choose Wuhan UHV.In electronic devices, we often see many magnetic rings and connecting cables forming an inductor (the wires in the cable are wound around the magnetic rings a few times as the inductor coil). It is a commonly used anti-interference component in electronic circuits and has a good shielding effect on high-frequency noise, so it is called an absorbing magnetic ring. Magnetic rings have different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies, and as the signal frequency increases, the impedance of the magnetic ring sharply increases.As we all know, the higher the frequency of a signal, the easier it is to radiate out. Generally, signal lines do not have shielding layers, and these signal lines become good

The working principle and main characteristics of series resonance
2025-11-07Series resonance is mainly composed of some variable frequency power supplies, transformers, reactors, and capacitive dividers during the production process. This product can effectively avoid damage to equipment caused by excessive voltage during use. The main working principle of this product is to effectively divert the voltage during use, ensuring that the resistance of the voltage in the entire circuit is at a minimum state, while maximizing the current. This can ensure the safety of the power system for a long time.Secondly, the most important feature of series resonance in use is its ability to effectively ensure the normal operation of the equipment, which is closely related to its working principle. In addition, during the use of this series resonant device, due to the relatively small power capacity, it is generally possible to effectively minimize the consumption of the entire power supply during the device's operation.
