Problems solved by technology

Therefore, most of the traditional armored removable high-voltage AC metal-enclosed switchgear cannot adapt to the occasions with high reliability requirements and relatively harsh natural environments and conditions such as underground, plateau, and coastal areas.
If SF6 gas-insulated switchgear is used, one is expensive, and the other is that SF6 gas, as one of the six warm and humid gases, has a greater impact on environmental pollution, so my country stipulates that it should not be used or used less

Abstract

The invention discloses all condition intelligent armored moving-type alternating current metal closed switch equipment. The equipment comprises a cabinet body and a low-pressure instrument chamber, a vacuum breaker chamber, a cable mounting chamber and a main bus chamber which are distributed on the cabinet body, wherein the main bus chamber is arranged at the rear upper part of the cabinet body and is provided with a middle insulating conduit; a vacuum breaker is arranged in the vacuum breaker chamber; a current transformer and an earthing switch are arranged in the cable mounting chamber; a second component for controlling and protecting is arranged in the low-pressure instrument chamber. The all condition intelligent armored moving-type alternating current metal closed switch equipment has the advantages of being reasonable in structure layout, high in reliability, high in intelligent degree and wide in application range.

Description

technical field [0001] The invention mainly relates to the field of switchgear, in particular to an armored removable high-voltage AC metal-enclosed switchgear. Background technique [0002] Armored removable high-voltage AC metal-enclosed switchgear is widely used in power systems, as well as industries such as railways, petrochemicals, metallurgy, industrial and mining enterprises, and high-rise buildings. At present, the most widely used products are air-insulated high-voltage AC metal-enclosed switchgear. However, due to the high-voltage AC metal-enclosed switchgear with air-based insulation is sensitive to ambient air quality, especially in harsh environmental pollution conditions such as relatively humid air, serious pollution, and corrosive gases, insulation accidents often occur, accounting for almost The accident rate of switchgear is more than 50%, seriously affecting the safe operation of the power system and the quality of power supply. [0003] Because my coun...
