Generally, people, including businesses, consider the advantages of an item when purchasing equipment. If the item is not excellent enough, they will definitely give up the purchase directly. Just as series resonance devices are commonly used in many enterprises, this also indicates that series resonance has many advantages, which are sufficient for major enterprises and factories to rely on it. What are its specific advantages?
Firstly, the series resonant device is very easy to operate, and due to its small size and weight, it is only one tenth to one-fifth of a typical experimental device, making it very easy to transport in the factory. This greatly increases work flexibility and eliminates various complex adjustment processes.
Secondly, its lifespan is very long. Due to its series resonance characteristics, when the circuit is in resonance state, if the weak point of the insulation of the tested object is broken down, the series resonance device will immediately take protective measures to reduce the current of the circuit to the normal current value or cut off the output. However, traditional devices generally cannot take good protective measures when encountering such situations, which may lead to damage to the experimental samples. So compared to other devices, series resonant devices can greatly prevent short-circuit current burn faults.
Thirdly, the equivalence of the experiment is good. The series resonant device has a much lower measured harmonic content than the national standard. It can effectively protect equipment such as generators from high-voltage harmonic damage. Moreover, series resonance can minimize the absorption of useless power, and basically the only power that the device draws from the group power supply is all the required effective power. Moreover, due to its excellent waveform and ease of detection, it is highly suitable for testing various experiments.
thus it can be seen. Series resonant devices have strong advantages over other devices, which is the main reason why many enterprises purchase series resonant devices when making purchases.
