What is the Insulation accident at the working voltage of the transformer?<\/h1>\n

Transformer is an indispensable and important equipment in the power system, and its insulation performance is directly related to the safe and stable operation of the whole system. At the working voltage, the transformer may be a variety of insulation accidents, the following are the main types:<\/p>\n

Contenu<\/span><\/b><\/h2>\n

1. Wrap insulation accident<\/em><\/h3>\n

Winding insulation accident is one of the most common insulation faults of transformers. Such accidents are usually manifested as the discharge and burning of winding main insulation, turn insulation or inter-segment insulation. Such accidents may cause a short circuit inside the transformer, and even cause a fire in serious cases.<\/p>\n

2. Insulation accident of casing<\/em><\/h3>\n

Bushing insulation accident mainly involves the discharge and damage of internal insulation of transformer casing, as well as the discharge of external insulation. Such accidents may lead to a casing explosion, posing a serious threat to the transformer and the surrounding equipment.<\/p>\n

3. Insulation accident of the tap switch<\/em><\/b><\/h3>\n

The insulation accident of the tap switch usually occurs in the room of the tap switch oil. Due to the decrease of the insulation strength of the oil, the arc may not be extinguished when the switch breaks, resulting in the burning of the on-load tap switch. In addition, the bare conductor between the non-excitation tap switch and the on-load tap switch may also discharge, causing a short-circuit accident.<\/p>\n

\"\"<\/a><\/p>\n

4. Iron core insulation accident<\/em><\/h3>\n

The core insulation accident is mainly caused by the insulation damage of the core silicon steel sheet or the insulation damage between the core frame joints. Such accidents can lead to multi-ground grounding, circulation and local overheating, and can burn the core in serious cases.<\/p>\n

En R\u00e9sum\u00e9<\/span><\/b><\/h2>\n

To sum up, the transformer may encounter various insulation problems such as winding insulation accident, casing insulation accident, tap switch insulation accident and iron core insulation accident under the working voltage. In order to ensure the safe and stable operation of the transformer, regular inspection and maintenance should be carried out to find and deal with potential insulation hazards in time<\/p>\n
