LDTRS low voltage reactor

The LSDFC type low voltage filter compensation component is a switching unit with relatively independent compensation and filtering function formed by combining capacitors and reactors according to the requirements according to the load. The filter reactor with a certain reactance coefficient and the filter capacitor with a certain capacity are appropriately proportioned Configuration to form a filter compensation loop to achieve the purpose of filter compensation. It consists of dry-type self-healing capacitor and low-voltage reactor。
