Energy-saving and voltage regulation amorphous alloy distribution transformer and regulation method thereof

Abstract

The invention discloses an energy-saving and voltage regulation amorphous alloy distribution transformer and a regulation method thereof. The energy-saving and voltage regulation amorphous alloy distribution transformer comprises a main transformer B1, a series transformer B2, a switch K1 and a switch K2, wherein the switches K1 and K2 have opening points and closing points, the opening points and the closing points are in linkage, a secondary-side winding of the main transformer B1 is connected with a primary-side winding of the series transformer B2, a secondary-side winding of the series transformer B2 is provided with three taps, the three taps are respectively connected with the closing point of the switch K2, the opening point of the switch K2 and the opening point of the switch K1, the closing point of the switch K2 and the opening point of the switch K2 are connected in parallel and short-connected with an output end of the secondary-side winding of the main transformer B1, the opening point of the switch K1 is connected with an outgoing end of the primary-side winding of the series transformer B2, and the closing point of the switch K1 is connected in parallel with the two ends of the primary-side winding of the series transformer B2. Through an automatic voltage regulation technology of winding taps of the transformer connected with the switches, the output voltage is automatically maintained to be (-10)-(+7)% when the voltage of a user end is in a change range of (-30)-(+7)%, and meanwhile, power is ensured not to be cut off during the whole switching process.

Description

technical field [0001] The invention relates to the technical field of transformers, and relates to a distribution transformer and an adjusting method thereof, in particular to an energy-saving voltage-regulating amorphous alloy distribution transformer and an adjusting method thereof. Background technique [0002] The existing amorphous alloy distribution transformer has about 70% less no-load loss than the silicon steel core transformer (ordinary transformer), and it is a distribution transformer with ideal energy saving effect at present. However, the existing distribution transformers have a fixed ratio, and their output voltage changes with the voltage of the distribution network. When the voltage is high, the loss of the equipment itself increases, and when the voltage is low, the electrical equipment may be damaged. This requires a A transformer capable of automatically stabilizing the output voltage solves the above-mentioned problems. Contents of the invention ...
