高低壓配電柜顧名思義就是電力供電系統中用于進行電能分配、控制、計量以及連接線纜的配電設備，一般供電局、變電所都是用高壓開關柜，然后經變壓器降壓低壓側引出到低壓配電柜，低壓配電柜在到各個用電的配電盤，控制箱，開關箱，里面就是通過將一些開關、斷路器、熔斷器、按鈕、指示燈、儀表、電線之類保護器件組裝成一體達到設計功能要求的配電裝置的設備。俗稱：高低壓開關柜或高低壓電氣成套設備。
　　As the name implies, high and low voltage power distribution cabinet is used for power distribution, control, measurement and cable connection in power supply system. Generally, high voltage switch cabinet is used in Power Supply Bureau and substation, and then it is led out to low-voltage distribution cabinet through the step-down low-voltage side of transformer. The low-voltage distribution cabinet is connected to each power distribution board, control box and switch box Switch, circuit breaker, fuse, button, indicator light, instrument, wire and other protective devices are assembled to meet the design function requirements of the power distribution device. Commonly known as: high and low voltage switchgear or high and low voltage electrical complete set of equipment.
