Internet of things based high- and low-voltage switchgear system

Abstract

The invention discloses an internet of things based high- and low-voltage switchgear system. The system is characterized by comprising a switchgear master control unit and an intelligent router unit. The intelligent router unit is used for establishing connections of all switchgear master control units of a power supply station and a client and for establishing a virtual local area network; the switchgear master control unit converts power signals periodically received, into power information; the power information is subjected to comprehensive judgement of operation load. The system is available for remote updating and debugging of system files of switchgear and for autonomous trip control; the system is capable of remotely monitoring and controlling the switchgear according to the transmitted power information, thus electrical equipment is more intelligent and equipment monitoring capacity and controllability is enhanced.

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
