The intelligent series resonance test power supply is an essential inspection technology equipment for voltage withstand testing in power infrastructure construction. By conducting voltage withstand testing on power electronic equipment information, it can be used to determine whether the cleanliness and insulation inside the teaching equipment enterprise can meet the national standard requirements, analyze whether the manufacturing and performance of the inspection equipment have good development, and ensure the safe and reliable operation of network equipment management. The intelligent series resonance test power supply uses frequency conversion to transform the voltage (air pressure variable) to achieve secondary boosting of the test circuit resonance. It is an indispensable detection related equipment in the process of voltage withstand testing for electrical engineering equipment problems. The experimental equipment for power frequency AC tests conducted in the past mainly consisted of high-voltage test transformers and power transformers The power capacity is large, the testing equipment is bulky, and it cannot automatically adjust frequency and voltage, making it difficult to adapt to the development trend of large power grids, high voltage, and high automation Compared with traditional high-voltage test frequency resonant power supplies, this research work is embedded with a new intelligent frequency and voltage method (insert), using high power (high power) (referring to the number of works done by the object per unit time) instead of traditional analog switching devices such as insulated gate bipolar transistors (IGBT) (defined as virtual reality things or processes) to generate the required test voltage AC voltage inverter device, while making the test product quality factor Q (usually 50 to 100) times higher pressure on the circuit using the principle of LC series resonance generated. The device is small in size, light in weight, and easy to operate on site. We can effectively protect the experimental device and system test samples. The main functions of this device are as follows:

1. Communication withstand voltage

The intelligent series resonance test device utilizes the series resonance between the reactance and capacitance test samples in the high-voltage circuit to generate high voltage and detect the insulation level of the test samples. The experimental teaching process can be achieved through manual and automatic control methods, and the generated high voltage can be analyzed and adjusted according to the voltage level system of the test product. It has a wide range, high reliability, and good stability (explanation: stable social stability; no changes have occurred). The resonant frequency range can reach 30-300Hz, which is close to the power frequency withstand voltage test.

2. Alarm and protection functions

The intelligent series resonance test device has intelligent protection and alarm functions. TestMeasure refers to the error message displayed on the human-machine interface of products undergoing stress testing, if they have automatic judgment, alarm, protection, and removal of power supply breakdown devices in the testing circuit. When the set test voltage is exceeded, there will also be some corresponding protective technology actions, with a well-developed alarm system function.

3. Storage and printing function

In addition to the above features, this device also includes storage and printing. During the information exchange and withstand voltage process of the TestMeasure product, the voltage values and related experimental research results during the withstand voltage process can be recorded and stored in a timely manner. The control voltage values and experimental analysis results during the test development process can be printed simultaneously through a printer, making it convenient for students to query in the future.
