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.

Abstract

The present invention relates to a partial discharge inspection system of a portable switch cabinet. The system comprises a signal acquisition unit and a data processing unit. Thesignal acquisition unit comprises a plurality of partial discharge state signal acquisition instruments that are capable of carrying out signal acquisition and single inspection, and providing simple on-site decision-making basis. The data processing unit comprises functional modules enabling data extraction, data analysis, and classification and separation according to types of faults. The system is characterized by using the technology of the Internet of Things, the embedded technology and the data mining technology to provide operation and maintenance personnel with an overall planof equipment state detection; adopting the Bluetooth technology to connect each signal collection unit of different partial discharge detection technology with the data processing unit to enable data transmission; and allowing the data processing unit to collect data provided by each acquisition unit, and transmitting the data to region servers with the help of WIFI, so that more macroscopic and comprehensive decision-making basis is provided, the operation and maintenance personnel is assisted to timely discover the equipment in the abnormal running state, and significant accidents are prevented from occurring.

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...
