Problems solved by technology
The components of the original DC power supply device are scattered, corresponding to the DC systems of different substations, and the models are not the same, which makes the preparation work extremely complicated and affects the work efficiency and time of emergency repairs
In addition, the on-site wiring of the device is complicated and unreliable, which reduces the safety of the device operation
[0006] The original DC power supply device has a single output, and there is no 48V DC power supply for communication
Because no voltage regulating equipment is used, the voltage of the control bus is unstable, which affects the reliable operation of the load of the control bus
[0007] The original battery pack (composed of 9 or 18 single cells) has many connectors and complicated connections

The invention discloses a mobile intelligent direct current power supply device, comprising a mobile control charging cabinet, a mobile pressure regulating feed cabinet and a mobile battery combined tank, wherein a first group of connecting interfaces on the mobile control charging cabinet are connected with a second group of connecting interfaces on the mobile pressure regulating feed cabinet byvirtue of cables; and the first group of connecting groups on the mobile control charging cabinet on the mobile control charging cabinet are also connected with the mobile battery combined tank by virtue of the cables. By applying the mobile intelligent direct current power supply device disclosed by the invention, electricity utilization reliability is improved, economic loss caused by fault andpower failure time is reduced, production cost is saved, working efficiency is improved, and safety management level is enhanced.
Description
technical field [0001] The invention relates to a mobile intelligent DC power supply device. Background technique [0002] The DC power supply device is mainly used to provide emergency power supply when an accident occurs in a power system substation and a temporary DC power supply when the DC power supply system of a substation is transformed. The basic functional requirements of the DC power supply unit are as follows: For different substations using DC power supplies with different nominal voltages, the DC power supply unit can provide DC power supplies with corresponding nominal voltages (DC110V or DC220V). At the same time, the device can also provide a DC power supply for communication with a nominal power supply of DC48V. Secondly, it has perfect monitoring and alarming and information output and sending functions. The fault information is prompted and alarmed by voice, which can run safely and stably under unattended conditions, reducing the number of monitoring pe...
