A high and low voltage switchgear system based on the Internet of Things

Abstract

The invention discloses a high and low voltage switchgear system based on the Internet of Things, which is characterized in that the high and low voltage switchgear system includes: a switchgear main control unit and an intelligent router unit; the intelligent router unit is used to establish all the switches in the power supply station The main control unit of the cabinet is connected with the client through the cloud server, and is used to construct a virtual local area network; the main control unit of the switch cabinet converts the power signal received regularly into power information; and comprehensively judges the workload of the power information. The invention can update and debug the remote system files of the switchgear, as well as autonomous trip control, and carry out remote monitoring and control on the switchgear according to the transmitted power information, thereby improving the intelligence of the electrical equipment, enhancing the monitoring ability and reliability of the equipment controlling.

Description

technical field [0001] The invention relates to the field of monitoring of power environment data, in particular to a high and low voltage switchgear system based on the Internet of Things. Background technique [0002] As a kind of electrical equipment, the switchgear is mainly used to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. At present, my country's switchgear is gradually developing in the direction of intelligence, but compared with developed countries, there is still a significant gap. [0003] First of all, domestic switchgear mainly adopts the method of regular maintenance, which is too blind and may cause unnecessary power outage losses; secondly, when an emergency occurs, maintenance personnel need to arrive at the scene for maintenance, which delays maintenance time and increases losses. There are many incoming line cabinets in the power dis...

Problems solved by technology

[0003] First of all, domestic switchgear mainly adopts the method of regular maintenance, which is too blind and may cause unnecessary power outage losses; secondly, when an emergency occurs, maintenance personnel need to arrive at the scene for maintenance, which delays maintenance time and increases losses. There are many incoming line cabinets in the power distribution room, and there are switches for controlling the on-off of equipment, and instrumentation equipment for monitoring and protecting the entire transmission line. Periodic, it is easy to cause inaccurate maintenance forecast and long maintenance delay

It is also impossible to browse the data and status of the switchgear anytime and anywhere, and to control the switchgear accordingly

[0004] In order to detect the stability of the voltage and current, various sensors are installed to monitor the switch, and the monitored signal is sent to the master station, mainly including the temperature, voltage, current and other indicators of the sensor, but the current switch cabinet is not intelligent. To achieve "intelligence" in the true sense, most of them have the following problems:

[0005] 1) Ineffective real-time monitoring: many monitoring of switchgear is based on timing monitoring. In case of abnormality, there is no sufficient response and early warning behavior. , The characteristics of effectiveness Send warning or abnormal information in real time, the time between capturing the abnormality and sending it may cause the instability of parameter data and voltage overload and other consequences

Therefore, not adopting a specific collection and forwarding method at a specific time has caused the problem that effective real-time monitoring cannot be carried out

[0006] 2) Lack of autonomy: due to the initial stage of intelligence, this stage lacks technical support for the processing of acquired parameters and lacks self-diagnosis technical support, so the captured state parameters, characteristic parameters, environmental parameters, etc., have not passed intelligent control in time The way to deal with it still depends on the relevant verification of personnel technology and the analysis of operating status to make processing behaviors. The intervention of personnel on detection, diagnosis analysis, and fault reporting directly affects the "intelligence" of products, and the lack of product autonomy It has also become an important problem facing the primary stage

[0007] 3) The maintenance of the switchgear system is inconvenient: because the traditional layout uses an ordinary router, it can only communicate with the server. When the personnel are not on site and the switchgear system is in urgent need of maintenance, the entire system will be paralyzed
