Novel single-phase voltage regulating and transforming system

Abstract

The invention discloses a novel single-phase voltage regulating and transforming system which comprises a single-phase voltage regulating controller, an alternating current contactor, a voltage stabilization inversion manager, a single-phase auto-transformer and a moulded case circuit breaker. The novel single-phase voltage regulating and transforming system is structurally characterized in that the single-phase voltage regulating controller is connected with the alternating current contactor through a copper conductor, the moulded case circuit breaker is connected with the voltage stabilization inversion manager through a copper conductor, the voltage stabilization inversion manager is connected with the alternating current contactor through a copper conductor, and the alternating current contactor is connected with the single-phase auto-transformer through a copper conductor. The single-phase voltage regulating controller automatically tracks the voltage change of a single-phase line to control the alternating current contactor in a corresponding channel to switch on or switch off so as to change the position of a shunting tap in the single-phase auto-transformer, so that the transformation ratio of the single-phase auto-transformer is changed, the effective number of turns of the single-phase auto-transformer is changed, and voltage regulation is achieved. The voltage stabilization inversion manager can regulate unstable voltages input from a live line and a null line of the moulded case circuit breaker to be stable output voltages for the alternating current contactor to use. The novel single-phase voltage regulating and transforming system achieves the purpose of intelligently regulating voltages.

Description

technical field [0001] The invention relates to a transformer, in particular to a novel single-phase voltage regulation and transformation system. Background technique [0002] The 0.4KV feeder in the rural distribution network is at the end of the power grid in the medium and low voltage distribution network, and is directly connected to the user. In rural low-power grids, there are situations such as thin user wiring diameters, long lines, and unreasonable load distribution. In recent years, with the vigorous promotion of household appliances going to the countryside, a large number of high-power single-phase electrical equipment has entered the households of ordinary people under the original electricity consumption environment of rural households, which has increased the instability of rural electricity consumption, making The voltage at the end of the line is too small, and the electrical equipment cannot be started normally, causing troubles in power consumption.
