Abstract

The invention discloses a dry-type transformer on-load capacity-regulating transition device and a capacity-regulating transformer, relates to the technical field of transformer capacity regulation, and solves the technical problems that the capacity-regulating transformer cannot provide power supply continuity in the voltage regulating process and cannot be suitable for places with high power supply reliability requirements. The dry-type transformer on-load capacity-regulating transition device comprises a high-voltage side switch, a low-voltage side switch, a transition transformer and a power mechanism, the high-voltage side switch is connected with the high-voltage winding of the transition transformer; the low-voltage side switch is connected with the low-voltage winding of the transition transformer; the power mechanism is connected with the high-voltage side switch and the low-voltage side switch. The capacity-regulating transformer comprises the dry-type transformer on-load capacity-regulating transition device. The capacity-regulating transformer with the dry-type transformer on-load capacity-regulating transition device has high power supply continuity, can be suitable for places with high requirements for power supply continuity, and is low in cost due to the fact that the number of the adopted vacuum bubbles is small.

Description

technical field [0001] The invention relates to the technical field of transformer capacity adjustment, in particular to an on-load capacity adjustment transition device for a dry-type transformer and a capacity adjustment transformer. Background technique [0002] When the power grid is in the peak period of electricity consumption, the demand for electricity is large, and the large-capacity transformer can meet the electricity demand; however, when the power grid is in the low period of electricity consumption, the demand for electricity is small, and the no-load loss of the large-capacity transformer A large amount of electric energy is wasted, and the power factor is also reduced. The capacity regulating transformer is installed in the existing power supply system. The capacity regulating transformer can judge the current load current according to the voltage and current of the low-voltage side, and can adjust the capacity itself according to the load of the power grid t...
