Description

technical field [0001] The invention relates to a secondary integrated device, in particular to a secondary integrated device for a high-voltage switch cabinet, and belongs to the technical field of secondary devices of electric power systems. Background technique [0002] The high-voltage switchgear is used for the connection and isolation of the high-voltage power grid, and is the key basic equipment for the safe and economical operation of the power grid. The high-voltage switchgear is assembled by many functional electrical appliances. These functional electrical appliances are generally divided into a primary part related to high voltage and high current and a secondary part that serves the safe and reliable operation of the primary part. The secondary part realizes comprehensive automation functions such as measurement, protection, control, signal, telecontrol, online monitoring and diagnosis of the primary part. [0003] The secondary part of the existing high-voltag...

AI Technical Summary

Problems solved by technology

[0005] 1) Using a variety of electrical appliances with multiple secondary functions, the quality is affected by different design, procurement, and assembly units;

[0006] 2) The overall quality inspection is difficult, and the overall quality cannot be guaranteed;

[0007] 3) The layout scheme of the secondary functional electrical appliances on the panel of the high-voltage switchgear is unreasonable, and the design and assembly units seldom conduct serious research on the intuitive display, manipulation control, layout design of the man-machine system and the combination of the operating system. Get the best working efficiency and feel safe and comfortable when working;

[0008] 4) The secondary functional electrical appliances are not optimally combined, there are many types and quantities, the number of connecting wires is large and the length is long, and the workload of mechanical installation and electrical wiring is large during assembly, so the overall cost is high;

[0009] 5) During operation and maintenance, it is difficult to identify a certain type of electrical failure, and at the same time, it is impossible to perform rapid overall replacement and maintenance, which prolongs the time for troubleshooting and increases the loss caused by power grid outages
