高壓瓷片電容用的外殼是陶瓷的,用來絕緣。高壓瓷片電容器一個主要的特點就是耐壓高,電壓一般大于1KV的電壓。高壓瓷片電容器常規有2KV、3KV、4KV電壓。常用于高壓場合。最高的可達30KV的電壓。
The shell of high voltage ceramic capacitor is ceramic, which is used for insulation. One of the main characteristics of high voltage ceramic capacitor is high voltage withstand, the voltage is generally greater than 1KV. High voltage ceramic capacitor has 2KV, 3KV, 4KV voltage. It is often used in high voltage applications. The highest voltage can reach 30KV.
高壓瓷片電容燒壞原因有幾種:
There are several reasons for the burning of high voltage ceramic capacitor
1.潮濕對電參數惡化的影響;
1. The influence of humidity on the deterioration of electrical parameters;
2.銀離子的遷移;
2. The migration of silver ions;
3.高壓瓷片電容在運用測試操作時,電容器投入時的電流過大,無任何無電壓保護措施;
3. When the high-voltage ceramic capacitor is used for test operation, the current when the capacitor is put into operation is too large, and there is no voltage protection measure;
4.高壓瓷片電容電容碰到了強大的電流,導致內部材料發熱,散熱不及時,造成熱擊穿損壞。
4. The high-voltage ceramic capacitor encounters a strong current, which leads to the internal material heating, and the heat dissipation is not timely, resulting in thermal breakdown damage.
那么高壓瓷片電容壞了有什么后果呢?
So what are the consequences of the failure of high voltage ceramic capacitor?
首先,排除高壓瓷片電容壞了會產生爆炸,不會對使用者人身造成傷害。壞了會有以下幾種現象產生:
First of all, it is ruled out that if the capacitor of high voltage porcelain chip is broken, it will cause explosion, which will not cause personal injury to users. If it is broken, the following phenomena will occur:
1.使用產品不通電;
1. The product is not powered on;
2.使用產品短路;
2. Use the product to short circuit;
3.使用產品失效。
3. The product is invalid.
如選到質量不好的高壓瓷片電容,在長期工作電壓下,內部殘存的氣泡產生局部放電現象。局部放電進一步導致絕緣損傷和老化。溫度也會上長,會導致高壓瓷片電容損壞,擊穿。
If the high-voltage ceramic capacitor with poor quality is selected, the residual bubbles will produce partial discharge under long-term working voltage. Partial discharge further leads to insulation damage and aging. The temperature will also increase, which will cause damage and breakdown of high-voltage ceramic capacitor.
