Embodiment Construction

[0067] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0068] Such as Figure 1-Figure 4 As shown, the method of metering and protection system of intelligent miniature circuit breaker, the method includes:

[0069] (2) measure the data on the circuit where the miniature circuit breaker is located;

[0070] (2) Protect the miniature circuit breaker. In this way, it can not only support the arc extinguishing, short circuit, and overload protection of traditional circuit breakers, but also provide overvoltage, undervoltage, and power limit protection functions with adjustable thresholds. The power is automatically cut off, and the function of automatically sending points after charging.

[0071] The data on the line where the miniature circuit breaker is located includes:

[0072] Assuming that when the user uses electricity, that is, when the power supply and the miniature circuit breaker are turned on, ...

Abstract

The invention discloses a metering and protecting system and method for an intelligent miniature circuit breaker. The metering and protecting system comprises a protection circuit and a metering circuit for the miniature circuit breaker. The protection circuit is used for collecting and integrating data to control the miniature circuit breaker to connect or disconnect a power supply connected withthe miniature circuit breaker. The metering circuit is used for metering voltage, current, frequency, power and electric energy data of a line where the miniature circuit breaker is located. The costof purchasing a large number of electric energy meters by a user is effectively reduced. More safe guarantee is provided, more convenient service is provided, the electric energy metering and billingfunction can be achieved, the electric quantity can be limited, automatic outage of the limited electric quantity is achieved, automatic point sending after money charging is achieved, overvoltage, undervoltage and power limiting protection functions with settable thresholds are provided, fire disasters are prevented, automatic wave recording can be achieved, and the functions of analyzing faultreasons of an electric power system can be achieved.

Description

technical field [0001] The invention relates to the technical field of miniature circuit breakers, and also belongs to the technical field of metering and protection, in particular to a metering and protection system and method for an intelligent miniature circuit breaker. Background technique [0002] A circuit breaker refers to a mechanical switching device that can connect, carry and break current under normal circuit conditions, and can also switch on, carry and break current for a certain period of time under specified abnormal circuit conditions. The miniature circuit breaker, referred to as MCB (Micro Circuit Breaker / Miniature Circuit Breaker), is the most widely used terminal protection device in the building electrical terminal power distribution device. It is used for single-phase and three-phase short-circuit, overload and overvoltage protection below 125A, including four types: single-pole 1P, two-pole 2P, three-pole 3P, and four-pole 4P. Specifically, circuit b...
