Problems solved by technology

However, users in urban residential quarters and public lighting only need 220V single-phase electricity. Therefore, each user has to share the cost of line loss and variable loss. Stability, many fault points, wide-ranging impact of power outage maintenance, high facility costs, and power supply and transformation facilities occupy valuable land resources

Abstract

The invention relates to one energy saving single phase imbed transducer device, wherein, its single transducer and low match box plug card form one integration architecture in vertical wall; the single transducer is composed of load switch, backup protection fuse breaker, plug melt, separate switch, initial coil, secondary coil, wire in terminal and outer terminal.

Description

technical field [0001] The invention relates to a power supply and transformation device, in particular to an energy-saving single-phase built-in power transformation device. Background technique [0002] At present, the power supply mode of urban residential quarters in my country is that the grid power transforms the 10KV high-voltage power to 380V through the switching station or box-type substation, and then delivers the power to each user through the cable branch box. However, users in urban residential quarters and public lighting only need 220V single-phase electricity. Therefore, each user has to share the cost of line loss and variable loss. Stability, many fault points, wide-ranging impact of power outage maintenance, high facility costs, and power supply and transformation facilities occupy valuable land resources. Contents of the invention [0003] The object of the present invention is to provide an energy-saving single-phase built-in substation device which ...
