A low-voltage distribution box for power distribution automation

Abstract

The invention discloses a low-voltage distribution box capable of realizing distribution automation, which comprises a box body, a general circuit breaker, a zero line connection bridge, a terminal block, a surge suppressor, a ground line connection bridge, an air switch, a multifunctional power meter, a live-line incoming line and a zero-line incoming line. The low-voltage distribution box capable of realizing distribution automation provided by the invention uses the multifunctional power meter to replace a traditional power meter, and performs optimization on a power supply circuit, thereby improving the inner space utilization rate of the distribution box and the intelligent degree of the operation, realizing distribution automation, and overcoming defects existing in the prior art. The low-voltage distribution box is simple in structure and easy to implement. The low-voltage distribution box can realize distribution automation and improve the power utilizations safety through performing targeted improvement on an internal metering function, a distribution automation function and a safety protection function of the distribution box.

Description

technical field [0001] The invention relates to on-off control, power metering and remote detection technology of a low-voltage distribution box, and belongs to the technical field of low-voltage distribution boxes of power distribution automation. Background technique [0002] The distribution box is the most common power distribution facility in daily life. With the improvement of people's living standards and the popularity of high-rise communities, the traditional distribution box cannot meet the needs of modern life. [0003] Traditional power distribution boxes are equipped with single-user ammeters. When the number of users increases, more ammeters need to be added, resulting in a large volume of the power distribution box and low utilization of internal space, resulting in poor heat dissipation performance and reduced use safety. In addition, the traditional power distribution box only has power consumption metering and separate on-off control, and the degree of inte...

Problems solved by technology

[0002] Distribution box is the most common power distribution facility in daily life. With the improvement of people's living standards and the popularity of high-rise residential areas, traditional distribution boxes cannot meet the needs of modern life.

[0003] The traditional distribution box is equipped with a single-user meter. When the number of users increases, it is necessary to increase the meter, resulting in a larger distribution box and low utilization of internal space, resulting in poor heat dissipation performance and reduced use safety.

In addition, the traditional power distribution box only has power consumption metering and separate on-off control, and the degree of intelligence is not high. As the country's requirements for power distribution automation become higher and higher, traditional power distribution boxes are gradually eliminated

[0004] In addition, electricity safety is an important part of family life. Natural disasters such as lightning strikes may cause abnormal home power supply current, which will cause equipment damage and affect personal safety. Therefore, it is necessary to improve the distribution box
