Embodiment approach

[0024] The invention provides a low-voltage intelligent power distribution self-healing and transfer power supply control system, which uses an intelligent switch to replace the traditional load switch to realize the control of transfer power supply, and automatically performs data collection, calculation, etc. through the smart switch and according to the calculation results Carry out power transfer control, and at the same time send the calculation results to the operation staff for review, so as to find line problems and formulate adjustment measures in time. According to different application scenarios of power transfer, the present invention includes two implementation modes: a low-voltage ring network power transfer control system and a key load power transfer control system.

[0025] The present invention provides a first embodiment. The low-voltage ring network transfer power supply control system includes multiple 0.4KV power supply lines, an intelligent plastic case s...

Abstract

The invention discloses a low-voltage intelligent power distribution self-healing and power supply switching control system, and the system comprises a plurality of 0.4 KV power supply load lines, an intelligent plastic shell switch and a background control system; and each power supply line comprises a transformer, a switch and a demand side electrical load. One end of the transformer is connected to a 10KV voltage line, and the other end of the transformer is electrically connected with a demand side electrical load through the switch and used for supplying power to the demand side electrical load. One end of the intelligent plastic shell switch is connected between the switch of one 0.4 KV power supply line and the demand side electrical load, and the other end of the intelligent plastic shell switch is connected into the switch of the other 0.4 KV power supply line and the demand side electrical load; and the intelligent plastic shell switch is used for acquiring power supply signals of incoming lines at two sides in real time and sending the power supply signals to the background control system so as to carry out closing control on the intelligent plastic shell switch, thereby realizing power transfer and supply of a demand side electrical load in any two 0.4 KV power supply lines. Automatic power supply switching can be realized.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution, in particular to a low-voltage intelligent power distribution self-healing and power transfer control system. Background technique [0002] At present, with the increase and expansion of users, sometimes new branch line loads are directly added to the previous power distribution room, resulting in some power distribution being in a high-load state for a long time; The output causes it to be in a low-load state for a long time, wasting the power distribution. In addition, these public transformer rooms are often distributed in a staggered manner or the main lines are quite close to each other in some places. Therefore, changing some power supply lines to closed-loop operation or switching power supply can not only reduce the burden of high-load distribution transformers, but also Ensure the reliable power supply of the distribution network to users and make full use of resou...
