一. Product Description

The anti-harmonic smart capacitor is a new-generation reactive power compensation device with high efficiency and energy saving, reduced line loss, improved power factor and power quality of 0.4kV low voltage power grid. It consists of intelligent measurement and control unit, zero-crossing switching unit, protection unit, filter reactor and low-voltage filter power capacitor. The traditional reactive power compensation device has changed the bulky and cumbersome structure mode, so that the new generation of low-voltage reactive power compensation equipment has better compensation effect, smaller volume, lower power consumption, lower price, more cost saving and more use. Flexible, more convenient to maintain, longer service life and higher reliability. It is suitable for reactive power compensation in places with very serious harmonics. It can operate reliably, does not generate resonance, has no amplification effect on harmonics, and is certain To the extent, it has the function of absorbing and eliminating harmonics. Among them, the 7% reactor is used in 5 (and 5 or more) harmonic-based electrical environments, and the 14% reactor is used in 3 (and more than 3) harmonics. Electrical environment.

二. Product model Specification

三. Terminal block arrangement and definition

The terminal of the product is divided into the power terminal and the measuring and controlling terminal, which are placed at the rear of the product. The three-phase compensation power terminal is: “UA .UB. UC”, and the phase-compensated power terminal is: “UA.UB.UC.UN” ”, the measurement and control of the online terminal uses plug-and-pull parts, which is convenient for on-site debugging and exchange. There are “IN, OUT, 1, 2, 3, 4, 5” serial number marks on the product, and should be fully paid attention when wiring or exchange.
