ICHYTI pv dc circuit breaker Development difficulties

The development of pv dc circuit breaker faces two main difficulties. Firstly, the DC system current does not naturally cross zero, so mature arc extinguishing technology cannot be used like AC circuit breakers; Secondly, there are a large number of inductive components in the DC system, which store a large amount of energy, increasing the difficulty of breaking DC fault currents.

However, with China's growth has come increasing pressure on natural resources, and supply constraints are beginning to emerge. This has led policymakers to look for ways to protect resources and boost efficiency. China is now investing heavily in green technologies and renewable energy sources such as solar and wind power, which will help to reduce its dependence on fossil fuels, and create new opportunities for growth.

Nevertheless, China's raw material advantage remains a critical factor in its international competitiveness, espousing the growth of new markets and supporting innovation, ultimately contributing to its economic development. As long as policymakers continue to promote sustainable management and conservation of natural resources, this advantage will remain central to China's position as a leading global manufacturer and economic power.
