Abstract

The invention provides a dry-type transformer on-load capacity regulating switch and a transformer, relates to the technical field of transformers, and aims at solving the technical problems that an existing capacity regulating switch is complex in transmission structure, and conversion is not in place easily and even fails. The dry-type transformer on-load capacity regulating switch comprises a high-voltage side switch, a low-voltage side switch, a moving plate and a driving mechanism, and the moving plate is connected to the driving mechanism; the high-voltage side switch comprises a solid-sealed polar pole in which a high-voltage vacuum bubble is arranged and a transmission piece; the upper end of the transmission piece is hinged with the lower end of the insulating pull rod of the solid-sealed polar pole; the low-voltage side switch comprises a moving contact and a static contact; and the moving contact is connected to the moving plate. The transformer is provided with the dry-typetransformer on-load capacity regulating switch. A permanent magnet operating mechanism is adopted, the transmission structure is simple, mechanical clamping stagnation and abrasion are not likely tohappen, and failure is avoided. Only the vacuum bubble is adopted on the high-voltage side, the air switch is adopted on the low-voltage side, the size of the capacity regulating switch is reduced, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an on-load capacity regulating switch of a dry-type transformer and a transformer. Background technique [0002] In the electric power supply system, some seasonal or periodic loads are often encountered. During the peak period of power consumption, the power demand is very large, and a large-capacity transformer is needed to meet the power demand; during the low power consumption period, the power demand is very small, which not only wastes a lot of power due to the large no-load loss of the large-capacity transformer, And reduce the power factor. The capacity regulating transformer can adjust the capacity according to the load, reduce the loss, improve the load factor of the transformer, and have high economic and social benefits. [0003] Dry-type transformer on-load capacity adjustment switch is to adjust the capacity of dry-type transformer by switching the series and...
