CC-TAIN11 51306515-175 high-voltage switchgear is a combination electrical appliance that can integrate circuit breakers, load switches, contactors, isolating switches, fuses, transformers, lightning arresters, capacitors, busbars, as well as corresponding measuring devices, signaling devices, interlocking devices, and communication systems into a metal casing of a rectangular cabinet.

Main deterioration factors of high-voltage switchgear

CC-TAIN11 51306515-175 Due to various reasons, the high-voltage switchgear in operation will deteriorate over time and constantly affect the safety of the power grid. The main deterioration factors are:

(1) Thermal degradation. Due to the increase in temperature during equipment operation, the insulation performance decreases.

(2) Electrical degradation. The concentration of electric fields in insulation materials can lead to a decrease in insulation performance.

(3) Mechanical degradation. Damage, deformation, cracking, and wear of parts caused by mechanical stress.

(4) Environmental degradation. Pollution, corrosion, moisture absorption, and deterioration of lubricating oil caused by environmental factors.
