Outdoor intelligent high-voltage alternating-current electric energy management control device

Abstract

The invention discloses an outdoor intelligent high-voltage alternating-current electric energy management control device which comprises a mounting frame, an isolation switch, a reignition-free vacuum circuit breaker, a current transformer, a zero-sequence current transformer, a voltage transformer and an intelligent control device. The mounting frame is arranged on a supporting pole. The reignition-free vacuum circuit breaker is connected with a high-voltage cable through the current transformer, the zero-sequence current transformer is arranged on the mounting rack, the isolating switch is connected with the upper end of the reignition-free vacuum circuit breaker, the voltage transformer is connected with the wire outlet end of the reignition-free vacuum circuit breaker, and the intelligent control device is arranged at the lower part of the mounting frame. According to the invention, the problem that the voltage-class outdoor zero-sequence current transformer causes a neck is solved, the abnormal state of current and voltage is detected and judged to realize rapid switching-on and switching-off operation control, the application range of the device is effectively expanded, the stability is improved, overcurrent, quick-break, grounding faults and the like of a lower system can be effectively identified, and a protection preset optimization function is realized; and accurate boundary protection ensures safe operation of a power grid.

Description

technical field [0001] The invention relates to the technical field of high-voltage equipment, in particular to an outdoor intelligent high-voltage AC power management and control device. Background technique [0002] Existing power terminal control equipment such as circuit breakers are only installed and operated independently outdoors, which is inconvenient in terms of management and operation, with incomplete protection functions, and it is difficult to find power abnormalities, often leading to the problem of increased faults caused by untimely control operations , and the lack of remote monitoring and operation capabilities is a major drawback of existing equipment, which needs to be improved urgently. Contents of the invention [0003] In view of the above technical problems, the present invention provides an outdoor intelligent high-voltage AC power management control device that is easy to operate and manage. [0004] In order to achieve the above object, the tec...
