Intelligent distribution box and system applied to low-voltage distribution transformer

Abstract

The invention discloses an intelligent distribution box and system applied to a low-voltage distribution transformer, and relates to power equipment, and the distribution box comprises a three-phase circuit breaker, an edge computing gateway and a reactive compensation unit. Thethree-phase circuit breaker is used for collecting power grid parameters according to a preset period, judging whether the power grid parameters are in a preset range or not, sending alarm information to the cloud end when the power grid parameters are not in the preset range, and implementing opening or switching on acompensation capacitor according to an instruction issued by the cloud end, wherein the power grid parameters comprise at least one of power grid voltage, power grid current, power grid frequency, power grid power factor, distribution box temperature and distribution box humidity; the edge computing gateway is used for communicating with the cloud end, performing edge computing according to the power grid parameters and uploading an edge computing result to the cloud end; and the reactive compensation unit is used for providing a plurality of compensation capacitors with different capacitancevalues according to the control signal of the three-phase circuit breaker. According to the invention, remote switching of the compensation capacitor and remote opening can be realized, and manpower is saved.

Description

technical field [0001] The invention relates to power equipment, especially an intelligent distribution box and system applied to low-voltage distribution transformers. Background technique [0002] With the development of the economy, people's demand for electric energy is also increasing, and the continuous construction of the power grid has also brought new problems. The distribution box is a general distribution center before electric energy enters the home. At present, the traditional distribution box is generally composed of air switch, leakage protector or fuse, ammeter, voltmeter and watt-hour meter. The collected data is relatively simple. In the absence of corresponding data processing modules, the collected electric energy indicators cannot be effectively analyzed. Moreover, the traditional distribution box does not have a reactive power compensation device, so it cannot realize on-site compensation for the reactive power deficit. In terms of maintenance work, t...

Problems solved by technology

The distribution box is a general distribution center before electric energy enters the home. At present, the traditional distribution box is generally composed of air switch, leakage protector or fuse, ammeter, voltmeter and watt-hour meter. The collected data is relatively simple. Lack of corresponding data processing modules, the collected electric energy indicators cannot be effectively analyzed

Moreover, the traditional distribution box does not have a reactive power compensation device, and cannot realize on-site compensation for the reactive power deficit

In the development of maintenance work, traditional distribution boxes mainly rely on telephone repairs, emergency repairs, and manual inspections to solve problems. There are many problems such as difficult recovery from power outages, untimely response, and high operation and maintenance costs.
