Portable switchgear partial discharge patrol detection system

Abstract

The invention relates to a portable switchgear partial discharge patrol detection system, which comprises a signal acquisition unit and a data processing unit. The signal acquisition unit comprises a plurality of partial discharge state signal acquisition instruments, and has the capability of signal acquisition, single-machine patrol detection and providing a simple on-site decision basis. The data processing unit comprises function modules of data extraction, data analysis and classification and separation and the like according to fault types. The portable switchgear partial discharge patrol detection system is characterized in that, through internet-of-thing technology, embedded technology and data mining technology, the system provides an overall plan for equipment state detection for operation and maintenance staffs; through bluetooth technology, signal acquisition units based on different partial discharge detection technologies and the data processing unit are networked for data transmission; and the data processing unit collects data of each acquisition unit and transmits the data to a regional server through WIFI. The system provides a more macroscopic and comprehensive decision basis, helps operation personnel to find equipment in an abnormal operating condition in time and prevents occurrence of major accidents.

Description

technical field [0001] The invention relates to a portable switch cabinet partial discharge inspection system based on Internet of Things technology, embedded technology and data mining technology. It is suitable for on-site inspection of insulation defects of switchgear. Background technique [0002] With the needs of power system reform and development and the improvement of users' requirements for power supply reliability, the reliability of high-voltage equipment operation has received more and more attention. However, the insulation problems of high-voltage equipment in the distribution network have become more and more prominent. Serious It affects the improvement of power supply reliability. [0003] Medium and high voltage switchgear is one of the main equipment in the power distribution network system. The quality of the insulation state of the switchgear directly affects the safety and reliability of the power supply system. If an electrical accident occurs, it wi...

Problems solved by technology

This type of equipment only has general inspection capabilities, and the data obtained from the inspection cannot be analyzed in an inductive manner. Therefore, inspectors can only judge the operating status of the switchgear based on the data detected at that time, and cannot judge the overall quality of the equipment. Whether there is a change, it cannot provide a more detailed and clear criterion on whether there is a problem with the switchgear

This type of detection equipment only has a signal acquisition unit, and it does not have the ability to store data, let alone analyze and synthesize data.

On the other hand, the detection capability of this type of equipment is closely related to the subjective initiative of the operator. The experience of the tester will directly affect the final decision, and there is a risk of misjudgment.
