Problems solved by technology

[0004] The intelligent power capacitor provided by the present invention has a simple overall structure and simple wiring, which fundamentally solves the problem of long-term power consumption by the discharge resistor. Since the discharge resistor works only when the capacitor exits the circuit, the resistor can be selected without restriction Large discharge resistance speeds up the discharge speed, creating conditions for fast switching of capacitors and prolonging the service life of discharge resistance

Abstract

Provided are an intelligent electric power capacitor and an application method thereof. The intelligent electric power capacitor comprises a framework and a discharge resistor, wherein an electric power capacitor and a permanent magnetic mechanism double-control switch are fixedly installed in the framework; the discharge resistor and the electric power capacitor are connected with two pairs of contacts of the permanent magnetic mechanism double-control switch respectively; the framework is further provided with an wiring port; and the wire of the permanent magnetic mechanism double-control switch is led out through the wiring port. The provided intelligent electric power capacitor has the advantages of simple overall structure and simple wiring. Problems are radically solved that the discharge resistor consumes electric power for a long time, and at the same time, discharge speed is accelerated, thereby creating conditions for fast switching of the capacitor.

Description

technical field [0001] The invention belongs to the technical field of reactive power compensation in electric power systems, and relates to a high-voltage reactive power compensation intelligent capacitor, in particular to an intelligent power capacitor and an application method thereof. Background technique [0002] Some of the existing power capacitors have no internal discharge resistors, and need to install external discharge resistors and protection circuits when using them. The overall structure and wiring are cumbersome. When connected to the circuit, the discharge resistor is connected at the same time, so that the discharge resistor will consume electric energy, and there is a phenomenon of wasting electric energy; in order to reduce energy consumption, the resistance value of the discharge resistor has to be reduced, which limits the discharge speed of the capacitor, which is not suitable for Occasions that need to switch capacitors quickly; and because the discha...
