With the rapid development of China's national economy, the supply and demand situation of oil and gas resources is becoming increasingly severe, and the import of oil and gas is increasing year by year, so it is urgent to expand the field of domestic oil and gas exploration and development. Strengthening the exploration and development of shale gas resources can make up for the lack of conventional oil and gas resources and promote the sustainable development of the oil and gas industry, which is of great significance for improving China's power structure and ensuring the security of national power supply.
CCTV News: China's first deep shale gas field with proven reserves of more than 100 billion cubic meters - Weirong shale gas field phase I 1 billion cubic meters annual production capacity construction project has been fully completed. The Weirong shale gas field is located in Neijiang City and Zigong City, Sichuan Province, and the construction is carried out in two phases, with an annual production capacity of 1 billion cubic meters and a daily gas production capacity of 3.5 million cubic meters. The construction of the second phase of 2 billion cubic meters of production capacity is accelerating, and when fully completed in 2022, the annual production capacity will reach 3 billion cubic meters, equivalent to the annual gas consumption of 16 million households.
Reynolds RNHV series high-voltage inverter governor and high-voltage inverter power skid are used in Sinopec Weirong shale gas project to escort shale gas long-distance pipeline compressors.

The inverter uses a power-saving method – Reynolds
As an electronic electric, the inverter itself also consumes electricity (about 3-5% of the rated power). A 1.5 hp air conditioner consumes 20-30W of electricity, which is equivalent to the length of a lamp. The inverter works under the power frequency and has the function of saving electricity, which is practical. However, the conditions are:
First, high power and ...

How long is the cable between the inverter and the motor allowed - Reynolds
The voltage waveform output by the inverter is only similar to a sine wave, but not a real sine wave, and its waveform contains a large number of harmonic components.
As we all know, the higher harmonics will increase the output current of the inverter, causing the motor winding to heat up.
