Compensation filter capacitor module
The pre-magnetization transformer is primarily used in power systems that involve large-capacity transformers, such as those in large ships and the metallurgical and petrochemical industries. By employing pre-magnetization technology, it suppresses the inrush current generated during no-load switching of large-capacity transformers.

Compensation filter capacitor module
Our compensation filter capacitor module is a self-healing high-grade metalized polypropylene film wound on the same concentric insulating tube (this can ensure that the winding has excellent accuracy), and through long-term vacuum drying (to ensure the working of the capacitor) Stable performance), a kind of capacitor formed by three cores inside corner or star connection. The current-carrying metal layers (electrodes) of the three inner capacitor cores are vaporized and deposited on one side of the membrane, and the electrodes are connected by metal layers sprayed on both ends of the capacitor cores. The capacitor is encapsulated in a cylindrical aluminum shell by inert gas or oil sand sealing technology.
The main features are:
1. The capacitor is equipped with discharge resistance to ensure that the capacitor terminal voltage drops below 50∨ after the capacitor is powered off.
2. The over-pressure cut-off device ensures that the capacitor is disconnected from the grid when it fails to ensure that the capacitor is explosion-proof.
3. Synchronize with Europe, adopt a one-time molded cylindrical aluminum alloy shell, which has the characteristics of good heat dissipation, light weight and small size
4. The dielectric has a self-healing function to cause voltage breakdown, and the metal monomer layer will generate high heat, so that the metal conductors around the breakdown point will quickly evaporate and dissipate. These escaping metal conductors are moved and are hitting within a few microseconds. The center pressure of the penetration point is pushed away to form an insulating area, so that the capacitor remains intact during and after the breakdown.
