Problems solved by technology

Domestic box-type substations use a three-phase power transformer whose wiring group is Y / Yo-12, which has a neutral point displacement on the low-voltage side and is easy to damage electrical appliances. The imported box-type substation wiring group is Δ / Yo-11
However, there is no on-load voltage regulating device for low voltage, and the quantitative power supply voltage cannot be guaranteed.

Abstract

The equipment consists of the intelligent typed high voltage switch cabinet, three phases five poles delta / Yo-11 connection, intelligent typed low switch cabinet and intelligent integrated console, 10kV dual power sources through the high voltage measuring cabinet, the intelligent high voltage power receiving cabinet and intelligent high voltage power feeding cabinet provides power to the transformer in three phases five poles delta / Yo-11 connection. The intelligent type low voltage cabinet distributes electricity. With two linked sections of low voltage buses, the stand-by generator and the intelligent integrated console being added, the intelligent equipment is built up.

Description

Technical field: [0001] The invention relates to an electric control device, in particular to an intelligent power transformation and distribution device. Background technique: [0002] Most of the currently used power distribution devices stay on the traditional structure, which is bulky and relatively expensive. Although the box-type transformers imported from abroad are small in size, their prices are higher than domestic ones. The domestic box-type substation uses a three-phase power transformer wiring group of Y / Yo-12, which has a neutral point displacement on the low-voltage side and is easy to damage electrical appliances. The imported box-type substation wiring group is Δ / Yo-11. However, there is no on-load voltage regulating device for low voltage, and the quantitative power supply voltage cannot be guaranteed. Invention content: [0003] The purpose of the present invention is to provide a 10KV dual power supply, which is controlled by an intelligent high-volta...
