摘要： A system for operating an on-load tap changer (OLTC) includes a plurality of legs that include mechanical switches. At least one leg switches from a first to a second tap of the OLTC on receipt of a tap change signal. At least one mechanical switch is activated to establish an electrical connection between one of the first and the second tap and a power terminal of the OLTC. Further, the system includes semiconductor switches that are parallel to the mechanical switches and when activated electrically couple one of the first and the second tap and the power terminal. The system includes a processing unit that selectively activates and deactivates the mechanical and semiconductor switches in such a way that electrical contact is maintained between at least one of the taps and the power terminal during the transition of at least one leg from the first tap to the second tap.

摘要： The present invention relates to a tap switch control method, which comprises the steps of: measuring data of a distribution system; calculating a second dead band and a reference voltage using the measured data; comparing the difference between the measured actual voltage and the reference voltage with a first dead band; comparing the difference between the actual voltage and the reference voltage with the second dead band, when the difference between the actual voltage and the reference voltage is outside the first dead band as a result of the comparison with the first dead band; and controlling the tap of the transformer, when the difference between the actual voltage and the reference voltage is outside the second dead band as a result of the comparison with the second dead band. Accordingly, it is possible to suppress a frequent operation of tap switching due to the fluctuations of the system and distributed power supply by applying the double dead band and to ensure the transformer's lifespan.

A second cam disk is also rotationally fixed on the switch shaft, and there are two further arms of U-shaped construction on the rocker lever arrangement. A lever has a free end provided with a second roller that co-operates with the second cam disk. This lever is between the further arms and mounted to be rotatable about an axis. A compression spring is provided between the lever and the further arms.

摘要： A method of switching taps by an on-load tap changer includes providing at least two fingers each comprising an impedance and a mechanical switch. When first and second mechanical switches of the first and second fingers are closed, they provide a connection between the first and second impedances of the first and second fingers and a power terminal of the on-load tap changer. The on-load tap changer is triggered to shift at least one of the fingers from a first tap to a second tap of the on-load tap changer when a tap change signal is received. A solid state switch connected between the first and second impedances is switched on to commutate a current from the first finger to the second finger during the tap change operation.
