Problems solved by technology

The hazards of unbalance mainly include the following aspects: the neutral line current causes line loss and wastes electric energy; the requirement for line capacity is high, especially the neutral line; it causes a single-phase voltage to deviate from the standard value, and when it is too high, it can burn electrical equipment. Electric equipment does not work properly when using low
This is a long-standing problem that has not been effectively resolved so far, resulting in a lot of waste, loss and inconvenience

Embodiment Construction

[0013] The system of the present invention is made up of detection module 2, server 1, switch module 3 and switch 4, and server 1 is connected with detection module 2 and switch module 3 respectively, and switch module 3 is connected switch 4, wherein

[0014] 1. Server: Electronic computer, using special control software to monitor the three-phase current data in real time. When the three-phase current difference exceeds the set value, the software system searches for a branch close to the current load at the controllable end, and controls to switch a branch load of a phase with a relatively large current to a phase with a relatively small current to go. The software system performs real-time regulation in this way, so that the current difference of each phase is controlled within the set allowable range, and the three-phase load balance is dynamically maintained.

[0015] 2. V / I detection module: used to detect the voltage and current of each phase in real time, and upload ...

Abstract

The invention relates to one power intelligent seamless three-phase balance system, which adopts test module, servo, switch module and switch to form power intelligent seamless system, wherein, the servo is connected to test module and switch module; the test module is to test three phase circuit each signal; servo is to test each phase signals for analysis, comparing and processing; the switch module is to receive process orders from servo to control its switch device; switch is fixed on each phase circuit switch.

Description

technical field [0001] The invention relates to the technical field of power supply, and relates to a system capable of balancing three-phase power during power transmission and supply. Background technique [0002] At present, the most common form of power transmission and supply is the three-phase four-wire system (380-volt three-phase AC power). This is true for large regional power grids and small residential units. Balance (the current of each phase is equal) is very important to the safety of the power grid, the safety of power consumption, and the efficiency of power consumption, so it should strive to achieve a balance in the design of capacity allocation. Mains electricity (220-volt single-phase electricity, commonly known as lighting electricity) uses one of the three phases, which is the main form of power supply (except power electrical equipment such as three-phase motors, machine tools, etc.), and the characteristic of electricity consumption is that the load ...
