Abstract

The invention discloses an integrated intelligent reactive compensation device, which is characterized in that the device has a supporting board, two power capacitor groups are arranged on the supporting board, a circuit breaker is arranged on the top cover of the capacitor bank, a wiring upright post is correspondingly connected with a switch device on a circuit board, and the capacitor bank is also provided with an upper cover, and an element and a circuit interface are provided on the upper cover. The device comprises no capacitor and current transformer, so as to reduce manufacturing cost under the prerequisite of assuring the detection accuracy. The invention has the advantages of real-time detection and control, complete and intuitive displayed items, wide capacity transformation ratio and accurate compensation, complete protection and warning functions, high degree of intellectualization, good compensation effect, small volume, modularized and compact structure, convenience for power grid and user capacity-increasing reconstruction, zero-cross switching, high reliability, and remarkably improved service life of product. Multiple compensation devices can be combined for operation to meet the requirement of large arranged capacity. A plurality of compensation device can be on-line operated, therefore, meeting the demands of large installed capacity.

Description

Technical field: [0001] The invention relates to power supply technology, and is a reactive power compensation device for power supply equipment, in particular, an integrated intelligent reactive power compensation device. Background technique: [0002] Reactive power compensation is an important energy-saving measure to improve the power factor of the electric load and reduce the loss caused by the reactive current in the electric energy transmission line. The traditional reactive power compensation system is mainly composed of power capacitors, electric power factor detection controllers, contactors for switching capacitors, current transformers, anti-inrush reactors and other components assembled in industrial boxes. Its disadvantages: large volume, large site occupation, high engineering cost and difficulty in compensation for capacity expansion and transformation, and the scope of application and site are limited. Invention content: [0003] The purpose of the presen...
