Control load intelligent circuit breaker

Abstract

The invention discloses a control load intelligent circuit breaker which comprises a shell, an inlet wire terminal and an outlet wire terminal. A power supply module is connected between any two phase wires in the shell and is connected to a central processor. The three-phase line in the shell is in series connection with a circuit breaker normally closed contact which is orderly connected to a circuit breaker release coil and a leakage protection module. The shell is also internally provided with an overload trip-out protective device. The central processor is also connected to three phase current sampling coils and is also connected to a power consumption monitoring module, a display module and a PC client. Whenever a power user connects a zero line, the central processor can normally work by using the voltage of 380v, thus the user can not circumvent the detection of the central processor, thus the user load is always monitored, the violated electricity consumption is avoided, the immoderate increase of a bench zone load is effectively suppressed, the line loss index is reduced, and the bench zone voltage quality is improved.

Problems solved by technology

[0002] The current-limiting leakage circuit breaker is used to control and protect the low-voltage distribution network. The current-limiting leakage circuit breaker in the prior art mainly uses the 220v mains on the low-voltage side as the working power supply. The above-mentioned intelligent circuit breaker mainly has the following shortcomings, and the user can bypass it. The central processor controls the mechanism to use electricity, so that the detection equipment does not work, and the user mainly realizes it through the following means:

[0003] 1. Neutral wire bypass type: After the neutral wire is drawn out from the ammeter, it does not pass through the current-limiting leakage circuit breaker but directly enters the home. At this time, the current-limiting leakage circuit breaker only introduces and distributes three live wires

[0004] 2. Missing neutral line: After the neutral line is drawn out from the meter, although there is a neutral line distributed, but the distributed neutral line is not connected to the current-limiting leakage circuit breaker, or the meter is not equipped with a neutral line, at this time the current-limiting leakage circuit breaker Only three live wires enter, and the zero wire at the exit is useless, and the voltage entering the user load terminal is 380V

[0005] Both of the above two methods do not provide a neutral line for the current-limiting leakage circuit breaker. This cheating behavior makes the load in the monitoring station area uncontrollable. The transformer is overloaded and overloaded. Severe overload can easily burn the transformer and cables At the same time, it endangers the safe operation of high-voltage lines and low-voltage transmission lines, resulting in high line loss and low voltage quality, which seriously affects the normal electricity consumption of residential lighting users, not only causing unpredictable losses to power supply companies, but also seriously disrupting the supply electric order
