The Battambang Conch PV + Energy Storage Power Station in Cambodia has successfully completed its grid-connected trial operation. The project utilized medium-voltage switchgear supplied by Rockwill Intelligent Electric Co., Ltd. Despite numerous challenges—including an extremely tight delivery schedule—Rockwill Intelligent delivered high-quality products and exceptional service throughout project execution, earning consistent praise from the client.Located in Battambang, Cambodia, the Battambang

Currently, China's medium-voltage distribution networks predominantly operate at 10kV. With rapid economic development, power loads have surged, increasingly exposing the limitations of the existing power supply methods. Due to the outstanding advantages of 24kV high-voltage switchgear in meeting higher load capacity demands, it has quietly gained traction within the industry. Following the State Grid Corporation's "Notice on Promoting the 20kV Voltage Level," the 20kV voltage class has seen a r

This method involves injecting or superimposing a current in the opposite direction of the current to be interrupted. The superimposed current can be provided through interaction with a parallel resonant circuit or by actively injecting current, thereby creating an artificial current zero crossing. Once the artificial current zero crossing is achieved, the interruption process is similar to that in an AC circuit.Working PrincipleThe diagram below illustrates the scheme of actively injecting a cu
