As the staff of the State Grid Hangzhou Yuhang District Power Supply Company clicked "One-click Sequence Control" on the background monitoring system, we saw that the indicators of each device lit up without manual operation, which made the Normal University It has become the first substation in Hangzhou to be put into operation using "one-click sequence control" technology, marking a solid step in the implementation of the Yuhang District Power Supply Company's "digital and intelligent residual power" action plan.

As we know, the circuit breaker in the substation is very important. The circuit breaker can efficiently connect and cut off the power circuit . At the same time, when a short circuit problem occurs, it can quickly and safely cut off the current, which is protective and effective. The role of controlling the power system. In the high-voltage circuit breaker , the hydraulic buffer is a very important core component. What is the role of the hydraulic buffer in the circuit breaker?
Hydraulic buffer
First, let’s understand the circuit breaker. It will undergo violent mechanical movement when opening and closing. High-speed movement will cause violent impact. The impact between metals will definitely rebound. The rebound will reduce the opening distance of the fracture. The pressure resistance of the fracture will be reduced, and the opening and closing may even fail. The special hydraulic buffer of the circuit breaker can effectively absorb the impact energy that occurs when opening the circuit breaker and minimize the rebound. The fast opening speed helps shorten the arcing time to reduce the impact on the opening and closing rate of the circuit breaker. . It can be seen that the hydraulic buffer promotes the high-efficiency operation of the circuit breaker, and it is very necessary to equip the circuit breaker with a hydraulic buffer.
Hydraulic buffer
One-button sequence control technology is applied in intelligent technology, transforming some complex and repetitive manual operation modes into one-button switching with fixed process operations, and personal safety is also effectively guaranteed. I believe that with the help of the hydraulic buffer, China Electric Power will usher in a more brilliant tomorrow
