Configuration of dual power supply cabinet

  Cabinet: the use of metal materials, such as cold-rolled steel or stainless steel, with good mechanical strength and protection performance, can effectively protect the internal electrical components from the external environment. The cabinet body usually includes the front door, the back door, the side panel, etc. . The door is provided with an observation window and an operating handle, which is convenient for operators to observe the internal situation and operate.
  Electrical components: including circuit breakers, contactors, relays, transfer switches, controllers, fuses, current transformers, voltmeters, ammeters and so on. Contactors and relays are used to control the on-off of circuits and the transmission of signals. Transfer switches are used to switch between two power supplies The controller is used to monitor the state of the circuit and realize circuit protection; the fuse is used for short circuit protection; the current transformer is used to measure the current in the circuit; the voltmeter and ammeter are used to display the voltage and current values of the power supply.
