A low-voltage power distribution switch system based on the Internet of Things

Abstract

The invention discloses a low-voltage power distribution switch system based on the Internet of Things, including: an incoming line cabinet, which includes a first incoming line receiving a low-voltage power supply input, a first circuit breaker connected to the first incoming line, and The first main bus connected to the first circuit breaker, the first measurement and control module for measuring the first main bus, and the first measurement and control module for transmitting the measurement results obtained by the first measurement and control module to the network end A communication module, and a first man-machine interface interacting with the operator; and an outlet cabinet, which includes a second incoming line connected to the first main bus, a second circuit breaker connected to the second incoming line, A feeder connected to the second circuit breaker, a second measurement and control module for measuring the feeder, and a second communication module for transmitting the measurement results obtained by the second measurement and control module to the network module, and a second man-machine interface interacting with the operator.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of low-voltage power distribution, and more specifically, relate to a low-voltage power distribution switch system based on the Internet of Things. Background technique [0002] A common low-voltage power distribution switch system generally includes an incoming line cabinet (also called a power receiving cabinet, used to receive electric energy from the grid), an outgoing line cabinet (also called a feeder cabinet or a power distribution cabinet, used for distributing electric energy), capacitor compensation Cabinet (also called capacitor cabinet, compensation cabinet, used to improve power factor), reactive power compensation cabinet (also called SVG cabinet, static var generator, referred to as SVG, used to improve power factor), active filter Cabinet (also known as APF cabinet, active power filter Active PowerFilter, referred to as APF, used for filtering), bus coupler cabinet (als...

AI Technical Summary

Problems solved by technology

[0003] In the currently widely used low-voltage power distribution switch system, each cabinet has no network IoT capability, so the data collection and transmission capabilities are poor, and a large amount of power distribution operation data is not collected and uploaded, resulting in backward operation guarantee and daily management methods, and it is impossible to realize intelligence. change

For example, the current existing cabinets often use panel instruments to display a small amount of random data, and it is impossible to fully grasp the operating data of the cabinet, and due to poor data collection and transmission capabilities, it is easy to generate high operational risks, so 24 hours of manual guarding is required , regular observation, and monitoring through manual meter reading records, does not have intensive management conditions, and human-computer interaction is also very inconvenient and intuitive

[0004] Moreover, the performance of each cabinet in the existing low-voltage power distribution switch system is poor in terms of human-computer interaction capabilities, and it is impossible to fully understand the operating status of each cabinet in real time, and it is easy to cause loss of key data, so it is not enough to ensure safe operation

Once a fault or accident occurs, the existing cabinet needs to be manually judged and checked, which makes the fault diagnosis time longer and has a greater impact on the user's use

In addition, due to the lack of Internet of Things capabilities, the existing low-voltage power distribution switch system cannot collect, store and transmit historical data during operation, which makes it very difficult to locate events and recall accidents after a fault occurs, and lacks good traceability and Analysis and improvement ability
