The invention discloses a direct-current power source screen. The direct-current power source screen comprises a cabinet, a direct-current voltage stabilizer, charging units, a storage battery pack and two silicon chain voltage reduction devices, wherein the direct-current voltage stabilizer, the charging units, the storage battery pack and the two silicon chain voltage reduction devices are arranged inside the cabinet. The two silicon chain voltage reduction devices are in parallel connection between the storage battery pack and a control bus; each silicon chain voltage reduction device is formed by connecting six to eight high-power diodes in series; the output terminal of each silicon chain voltage reduction device is further connected with an LED in series; the anode terminal of each silicon chain voltage reduction device is connected with the output terminal of the storage battery pack; the cathode terminal of each silicon chain voltage reduction device is connected with to the control bus. The output terminal of each charging unit is connected with an LED in series, wherein the cathode of the LED is connected to the input terminal of the storage battery pack, and the output terminals of all the charging units are connected in parallel. The cabinet is composed of insulating panels, wherein slice-shaped rectangular wood trim strips are pasted on the obverse side of the cabinet. The direct-current power source screen overcomes the shortcoming that oil paint spraying causes environment pollution, and the danger that, caused by electric leakage of the power source screen, it is avoided that people get an electric shock since the cabinet is composed of the insulating panels.
Description
technical field [0001] The invention relates to a direct current power supply screen, in particular to a direct current power supply screen provided with a file box. Background technique [0002] The power operating power supply in power plants and substations is currently using DC power supply, and the DC screen is used to supply this DC power supply. It provides power for control loads, power loads, and DC accident lighting loads. It is a contemporary power system. The basis for control and protection. The development of modern science and technology, especially computer technology and communication technology, makes the power system develop towards the direction of comprehensive automation, unattended power station and networked centralized management. As an important part of the power system, the DC power system (DC screen) Its own power supply quality, reliability and degree of automation need to be further improved, and therefore a large number of advanced science and...
