description | The utility model provides a 10kV automatic switching reactive power compensator which comprises a high-voltage switchgear, a wire inlet cabinet, and a plurality of capacitor cabinets which are parallelly connected with a high-voltage bus in the wire inlet cabinet. The wire inlet end of the wire inlet cabinet is connected with the wire outlet end of the high-voltage switchgear through the high-voltage bus. The wire outlet end of the wire inlet cabinet is connected with the input end of a contactor through an impedance grounding device and a second isolating switch. The output end of the contact is grounded through a lightning arresting grounding device, a capacitor, a second current transformer and a reactor successively. A voltage transformer is parallelly connected with two ends of the capacitor. The input end of a controlling acquisition unit and the input end of a protecting acquisition unit are respectively used for acquiring sampling signals of a main bus and various sets of protecting sampling signals. After the output end of the controlling acquisition unit and the output end of the protecting acquisition unit are parallelly connected, the parallelly connected output end is connected with coils of vacuum contactors in the plurality of capacitor cabinets. The 10kV automatic switching reactive power compensator settles problems of no automatic switching function and potential safety hazard in a traditional reactive power compensator according to prior art. |
