Abstract

The invention provides a power distribution box, comprising a box body; a distribution unit is arranged in the box body and is connected with a plurality of connector modules connected to a current breaker, the current breaker is connected with an external three-phase power line through a switch module, the distribution unit is connected with a distribution actuating module and a display module, and the distribution actuating module is connected to a user terminal. The power distribution box can avoid three-phase load imbalance of a low-voltage line and provide intelligent power distribution.

Description

technical field [0001] The invention belongs to the technical field of electric power, in particular to a distribution box. Background technique [0002] With the continuous improvement of people's living standards, a large number of high-power single-phase household appliances, such as: air conditioners, electric water heaters, rice cookers, microwave ovens, ovens, etc., have entered ordinary households. These household appliances bring people comfort, convenience and fast life. , It also has a certain impact on the safety and economic operation of the low-voltage power supply system of the power supply department. refer to figure 1 , the existing power supply network leads three three-phase power supply lines from the low-voltage side of the 10KV / 380V / 220V distribution transformer through the air switch and AC contactor, and the A-phase, B-phase, and C-phase lines of each three-phase power supply line are respectively Access multiple single-phase users. Due to the unbal...
