Embodiment Construction
[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0031] The application provides an on-load tap changer and a voltage regulating device. Voltage regulating equipment includes on-load tap changer and voltage regulating transformer. On-load tap changer refers to a voltage regulating device suitable for operating under the excitation or load of the voltage regulating transformer and used to change the tap connection position of the winding of the voltage regulating transformer. Its basic principle is to ensure that the load current is not interrupted. In some cases, the switch between the taps in the coil winding of the vo...

The invention relates to an on-load tap-changer, a control method and device thereof, a voltage regulating device, a storage medium and a computer device. The on-load tap-changer comprises a first switcher, a second switcher and a control circuit, and the control circuit is used for adjusting the on-off states of a first switch end and a second switch end of the first switcher and the on-off states of a first switch end and a second switch end of the second switcher, so that one of a first tapping point, a second tapping point and a third tapping point is controlled to be connected with the second end of a coil winding of a voltage regulating transformer, wherein at most one of the first switch end and the second switch end of the first switcher is in a closed state, and at most one of thefirst switch end and the second switch end of the second switcher is in a closed state. The internal circuit structure of the on-load tap-changer is simple.
Description
technical field [0001] The present invention relates to the technical field of electric power systems, in particular to an on-load tap changer and its control method, device, voltage regulating equipment, storage medium and computer equipment. Background technique [0002] Changes in the operation mode of the power system will cause changes in the bus voltage, and the power system has strict requirements on the range of the bus voltage. Therefore, it is necessary to adjust the bus voltage when it changes. Currently, an on-load tap changer is used to switch between the taps of the voltage regulating transformer to change the turns ratio of the voltage regulating transformer to achieve the purpose of voltage regulation. [0003] The traditional on-load tap-changer is suitable for the situation where the tap transformer needs to switch a large number of taps. In the power distribution room, in order to reduce the area of the power distribution room and simplify the structure...
