Problems solved by technology

In order to solve the contradiction between safety and power, most of the existing high-power electrical equipment in explosive environments adopts explosion-proof treatment, but the explosion-proof layer itself that can be achieved at present is very heavy, which brings many difficulties to portability and application.

Abstract

A distributed power supply device comprises a plurality of batteries or battery pack units which are cooperated to supply power for each electrical appliance of same equipment. The distributed power supply device comprises a controller, a control signal channel, a plurality of batteries or battery packs, a plurality of electrical appliances and a power circuit connecting the batteries or battery packs with the electrical appliances. Each battery or battery pack supplies power to one electrical appliance or a part of the electrical appliances. Physical isolation and electrical isolation are adopted among the plurality of the batteries or the battery packs, and among the corresponding electrical appliances, therefore, the plurality of batteries or battery packs and the corresponding electrical appliances can be taken as a plurality of independent units electrically, the electric power can be effectively distributed onto a plurality of independent lines, and further the safety of the system is improved in a specific environment. Meanwhile, the on/off state and the running state of each electrical appliance are uniformly controlled by the controller, so that the distributed power supply device has the advantages of central-station control and convenience in operation.

Description

technical field [0001] The invention belongs to the field of power supply systems, and in particular relates to a distributed combined power supply device. Background technique [0002] In disaster rescue, fire-fighting and detonation and other applications, the environment is often full of flammable and explosive gases, liquids or dust. In order to ensure safety, the voltage, current, inductance, capacitance and other characteristics of electrical appliances must meet certain requirements. For example, the national standard GB 3836 "Requirements for Explosive Atmospheres" Part 4 Figure A.1 gives the maximum allowable value of current / voltage for a purely resistive circuit. These limitations, especially the limitations of voltage and current, essentially limit the maximum power allowed by electrical appliances, thus greatly limiting the power consumption of some relatively high-power electrical appliances, such as high-power drive motors and high-power lighting equipment. ...
