Abstract

The invention provides a power distribution cabinet and an application method thereof, the power distribution cabinet comprises an SVG unit, a common compensation unit, a separate compensation unit, a first current transformer and a controller; after the current transformer detects each phase of phase current flowing into the SVG unit, the controller controls the SVG unit to execute three-phase current compensation operation according to each phase of phase current. The SVG unit can be used for three-phase current balance compensation, and three-phase balance is ensured.

Description

technical field [0001] The invention relates to the field of power distribution, more specifically, to a power distribution cabinet and an application method thereof. Background technique [0002] With the continuous deepening of the transformation of rural power grids, a large number of integrated power distribution cabinets (JP cabinets) for distribution transformers have been used in rural power lines and distribution stations. JP cabinet is designed to meet the standardization, miniaturization and outdoor requirements of rural low-voltage power distribution equipment. It integrates power distribution, measurement, protection (overload, short circuit, leakage, snow prevention), and capacitor reactive power compensation. But the existing JP cabinet does not have the three-phase unbalance compensation function. Contents of the invention [0003] In view of this, the present invention provides a power distribution cabinet and its application method to solve the problem th...
