Automatic control of power equipment and on-site unattended operation has become an inevitable trend. At present, the smart grid transformation project has been fully carried out. It is required to establish a centralized monitoring and control center that can output relevant data of key equipment such as power distribution plants, substations, and transmission lines.

Environmental parameters and images are monitored in order to be able to directly understand and grasp the situation of each key equipment in real-time and directly respond to the occurrence of the situation.

The application of infrared thermal imaging camera diagnostic technology has solved a large number of heat radiation failure problems in equipment operation, and the economic and social benefits are significant.

Because this technology is a non-contact, long-distance thermal imaging detection of the infrared light radiated from the surface of the device, and is not interfered with by electromagnetic fields, it has the characteristics of intuitive, accurate, high sensitivity, fast, safe, and wide application range, which can fundamentally change early manual inspection of operating equipment's hidden trouble diagnosis method.

There are many types of power equipment failures, but most of them are accompanied by heat generation. In the electric power industry, infrared thermal imaging cameras have been used for the safety inspection and repair of equipment for a long time to detect thermal defects in electrical equipment and lines. Infrared imaging technology can be used to carry out the following electrical equipment status detection and fault diagnosis.

Transformer

The transformer cabinet is abnormally overheated, the eddy current is overheated, the upper and lower ends of the high and low voltage bushings are not well connected, and the oil-filled bushings are short of oil (low oil level).

lightning arrester

Various types of lightning arresters have damp defects in the center, aging of the inner center components, or abnormal changes in nonlinear characteristics.

Capacitor

Overheating of various capacitors, poor oil insulation of coupling capacitors, and oil shortage (low oil level) defects.

Breaker

Overheating of the conductive fluid is caused by poor contact, dampness inside of the insulating porcelain sleeve, poor contact between moving and static contacts, lack of oil, poor connection of the intermediate contacts, and poor contact of the static contact base.

Insulator string

Poor porcelain, contamination, low value, and zero value cause the failure of the insulator.

Instrument transformer

Insulation failure, coil and core failure, internal connection failure, and lack of oil.

Dynamo

Stator core insulation defects, stator bar joints, brushes, and slip rings are in poor contact.

Power cables and wires

Diversion and overheating faults caused by poor contact of the three-phase outlet connector of the cable head, diversion and overheating faults caused by poor contact of the internal joints, partial insulation failure of the cable head, and cable outlet sleeve failure.

Isolating switch

Pollution on the surface of the porcelain column, cracks in the porcelain column, deterioration of the insulation pattern, and poor isolation contact.

High-voltage transmission wires and crimping tubes

It is mainly to detect the poor contact of the connector.
