Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0015] The present invention provides a multi-purpose low-voltage smart capacitor, which includes a first power capacitor and a second power capacitor that can work independently or alternately or simultaneously, and the structures of the two power capacitors and The connection method is the same, and the three capacitors are connected in parallel between the AB phase, BC phase and AC phase of the ABC three-phase grid to realize reactive power compensation. High temperature leads to failure and damage of the capacitor. In the present invention, a temperature sensor is arranged between the first power capacitor and the second power capacitor for real-time monitoring of the temperature of the power capacitor. Preferably, the first power capacitor and the second power capacitor ...

Abstract

The invention discloses a multipurpose low-voltage intelligent capacitor. The multipurpose low-voltage intelligent capacitor comprises a first power capacitor, a second power capacitor and a temperature sensor between the first power capacitor and the second power capacitor, so that reactive power compensation is achieved. For achieving the multipurpose and intelligent effect, the multipurpose low-voltage intelligent capacitor further comprises a small breaker connected with a three-phase power grid, a hurl-slices switch, a microprocessor system, a liquid crystal displayer, signal indicator lights, an RS485 interface communication module, a key configuration module and the like, and the low-voltage intelligent capacitor can be obtained by connecting the modules correspondingly. The multipurpose low-voltage intelligent capacitor can monitor relevant parameters of the power grid in real time, and the relevant parameters can be displayed by the liquid crystal displayer and the signal indicator lights. The multipurpose low-voltage intelligent capacitor is powerful in function, wide in application, suitable for reactive in-place dispersion compensation, reactive centralized compensation and low-voltage reactive in-place grouping compensation, and wide in application prospect.

Description

technical field [0001] The invention relates to the field of power supply network control, in particular to a multi-purpose low-voltage intelligent capacitor. Background technique [0002] Under normal circumstances, electrical equipment not only needs to obtain active power from the power supply, but also needs to obtain reactive power from the power supply. If the reactive power in the grid is in short supply, the electrical equipment will not have enough reactive power to establish a normal electromagnetic field, then these electrical equipment will not be able to maintain the work under rated conditions, and the terminal voltage of the electrical equipment will drop, thus It affects the normal operation of electrical equipment, so it is particularly important to intelligentize, integrate, and safely and reliably compensate reactive power in the power grid. The traditional reactive power compensation device consists of a low-voltage intelligent reactive power compensation...
