Detailed introduction of the invalid reason of SMC insulation board

There are many reasons for the failure of the SMC insulation board, and one of the more critical factors is caused by aging. If it is kneaded by other objects at high temperature, the insulator may be short-circuited, which will cause the insulation board to fail. Let’s give us a detailed introduction to the reasons for the failure.

(1) Burburinta gaasta

When the electric field strength of the SMC insulation board exceeds a certain value, it will cause gap breakdown. If the gap is too small, the electric field strength will increase and cause gas breakdown. Commonly, capacitors break down due to excessively high applied voltage, electric sparks caused by exposed wires, and arcs when the switch is closed. These conditions indicate that they no longer have insulation properties.

(2) Burburinta dareeraha dareeraha ah

The electric strength of liquid dielectric is much higher than that of gas under standard state. If the oil contains impurities such as moisture, its electrical strength will be severely reduced, and it is prone to breakdown, leading to failure of the insulating material.

(3) Dusha sare ee burburka

Isticmaalka guddiga dahaarka ee SMC, inta badan waxaa jira gaas ama dareere warbaahin ah oo ku wareegsan dhexdhexaadka adag, iyo burburku inta badan wuxuu ku dhacaa isdhexgalka labada dielectrics iyo dhinaca leh awoodda korantada ee hoose, taas oo loo yaqaan burburka gurguurta. Korantada burburka ee dusha sare waxay ka hooseysaa kan hal dielectric. Cidhifka korantada capacitor-ka, insulator-ka dhamaadka siliga mootada (ul) wuxuu u nugul yahay dareeraha gurguurta, kaas oo waxyeelo weyn u geysta dahaarka una horseeda guul darro.

The above is an introduction to the reasons for the failure of the SMC insulation board. In the face of different breakdown methods, the results have led to the failure of the insulation board and can no longer exert its due performance. Therefore, we must pay attention to the electrical The control of the equipment prevents unnecessary damage during operation and affects the insulation effect.
