The invention discloses a high-voltage power distribution cabinet, which comprises: a first power supply branch, wherein the first power supply branch is electrically connected with a power supply endwire inlet terminal, an isolation switch module, a circuit breaker module and a first wire outlet terminal in sequence, and the first wire outlet terminal is connected with a first transformer; and asecond power supply branch electrically connected with the power supply end wire inlet terminal, the isolation switch module and a primary coil of a second transformer in sequence, wherein the firstsecondary coil of the second transformer is connected with an auxiliary power supply wire outlet terminal, the second secondary coil of the second transformer is connected with a detection module, andthe detection module is configured to be used for detecting actual current and / or actual voltage. According to the invention, the high-voltage power distribution cabinet can provide a power supply for a power utilization function device in the high-voltage power distribution cabinet in an occasion without an additional auxiliary control power supply and with a large-capacity main transformer connected at the back stage, is flexible to use, and is particularly suitable for being matched with different outdoor power distribution systems.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a high-voltage power distribution cabinet. Background technique [0002] The high-voltage power distribution cabinet is an indispensable electrical equipment in the power distribution system, which directly affects the normal operation of the power distribution system and the quality of power supply services. The main function of the high-voltage power distribution cabinet is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The traditional high-voltage power distribution cabinet is mainly composed of two parts: the cabinet body and the circuit breaker. Circuit breakers, isolating switches, load switches, operating mechanisms and various protection devices. [0003] Traditional power distribution systems integrated with high-voltage pow...
