The term “distributed control system” was derived by translating the product name of a foreign company. Due to the numerous manufacturers and varying system designs, as well as the diverse functions and features of each system, the naming of these products also varies. In China, there are different names for the product, the most…
A circuit breaker is a switch device that can close, carry and open the current under normal circuit conditions, and can also close, carry and open the current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers based on their application scope. The boundary…
