Abstract
An existing low voltage static compensator has problems in usage that a low voltage fixed capacitor bank compensation capacity cannot satisfy real adjustment, so over-compensation or under-compensation always happens; continuous and frequent switching cannot be realized; switching capacitor is slow in respond speed, dynamic idle cannot be compensated, and fast changing load cannot be compensated; continuous compensation cannot be realized, and power factors are improved in limitation; and system harmonic wave cannot be eliminated. Aiming at the problems, the utility model provides a low voltage static complex compensation cabinet comprising a cabinet body; a blower is fixed on a through hole of a top plate in the cabinet body; micro breakers, a switching capacitor, a lightning arrester, electrothermal relays and three-phase parallel capacitors are electrically connected in the cabinet body; and electric quantity instruments, buttons, indication lamps and change over switches electrically connected with the cabinet body are fixed on a door plate of the cabinet body. The low voltage static complex compensation cabinet is characterized in that an electric air switch, fuses, current transformers, a reactor and a low voltage static wattless generator are fixed in a parallel manner on top of the micro breakers and 0.4kv circuit system fixed in the cabinet body.
