有载分接开关(On-load tap changer, OLTC)是在

Load tap-changer (On-load tap changer, OLTC) borne in the power system reactive power regulation, load voltage stabilizing role, is the only one of the combined mechanical and electrical equipment frequently operated power transformer. According to statistics, OLTC transformer fault caused by more than 20% of its total failure, mechanical failure and more than 90%.

On-load tap switch (ON-load tap changer, OLTC) is the only mechanical and electrical integrated equipment that is operated frequently by power transformers, which plays an important role in reactive regulation and stabilizing load voltage in power systems. According to statistics, OLTC caused transformer failures accounted for more than 20% of its total failure, and mechanical failure of more than 90%.

On load tap changer (OLTC) plays an important role in the power system, such as reactive power regulation, load voltage stabilization, etc. it is the only frequently operated mechanical and electrical equipment of power transformer. According to statistics, OLTC induced transformer faults account for more than 20% of its total faults, and mechanical faults account for more than 90%.
