Intermediate Frequency AC Power Supplies The IFP series is AC Power Supplies with a constant 400Hz output frequency and adjustable output voltage, based on the same technical principle as the adjustable AC power supplies of SPWM method, IGBT module design and D/A conversion technology. The difference is that the output frequency of the Intermediate Frequency AC Power Supplies is constant at 400 Hz, it is a replacement product of unit type variable frequency power supplies with higher output frequency accuracy and stability.

The person in charge of the Liudaogou Village Committee told reporters that in recent years, the power department issued a “Safety Supervision Notice†to them several times and ordered them to rectify the problem of transformer height. However, the cost of upgrading the line was nearly 100,000. Yuan, because of their limited funds, this problem has been delayed until now. Respond.
Afterwards, the reporter reported this issue to the Tanggu Power Management Department. A person in charge of Wang Xing told reporters that they had sent people to the site to investigate and set up barriers around transformers to prevent electric shocks from nearby pedestrians. The next step is to negotiate with the local village committee about the cost of rebuilding, and strive to completely eliminate the hidden danger of electric shock during the year.
The output power of single-phase Intermediate Frequency AC Power Supplies ranges from 500VA to 200KVA, and the output power of three-phase Intermediate Frequency AC Power Supplies ranges from 3KVA to 600KVA. The output voltage of both types can be divided into 0 ~ 150Vac, 150 ~ 300Vac with 400Hz fixed output frequency. This series of AC power supplies are featured for high precision, stable output, high display resolution, low waveform distortion and complete protection functions.
Through the friendly operation panel, you can read the output data such as output voltage, output current, output power, power factor, etc., providing accurate data records for your test, and can add RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies, Currently, the Intermediate Frequency AC Power Supplies are mainly used for aircraft and mechanical equipment, radar, navigation and other military electronic equipment and other occasions that require 400Hz intermediate frequency output.
Yesterday, Mr. Lin, who lives in Building No. 7 of Xinmei Park, called the newspaper, saying that several high-voltage transformers located near the Jintang Highway were too low in height and there were no protective measures around them. This caused serious safety problems because of several personal witnesses. The passer-by shocked the passers-by, and Mr. Lin told reporters that the relevant departments could take safety measures as soon as possible. "Dwarf" transformers are located in residential areas Yesterday, the reporter conducted investigations on the high-voltage power supply facilities of the Donggu Village to Xinmeiyuan section of the Jintang Highway. The reporter saw a transformer with the serial number BH2203 and high voltage of 315kV near Xinmei Park. There are neither high-pressure and dangerous warning signs nor related protective measures. What makes people worry is that the high-voltage part is within reach. The reporter measured his height with a tape measure that he carried and found that his “height†was only 1.6 meters. The nearby branches can almost touch the outside of the transformer. Later, the reporter also found two transformers with a height of 300 kV or more and a height of less than 2 meters in the villages of Dongcun and Nanbabao. These power facilities with serious safety hazards are all located in densely populated residential areas. “Higher†costs are more expensive than the village committee can't bear. According to the “Regulations on the Maintenance of Electric Power Facilities,†pole transformers must be 2.5 meters above ground, and must have warning signs such as high-voltage hazards. From this point of view, these “gnomes†Transformers have violated national standards. During the visit, the reporter also discovered that these transformers have been used for more than 10 years. Why has such a large hidden danger in 10 years been there? The reporter found the property rights unit of these transformers - the local village committee.
