Abstract

The invention discloses a large-capacity explosion-proof type uninterrupted power system and an explosion-suppression cavity for the power system. The power system comprises the explosion-suppression cavity (1) and a control circuit (2); the explosion-suppression cavity (1) comprises a main cavity (101), a wiring cavity (102), a battery cavity (103), an explosion-suppression observation window (104), a cable entry (105), an explosion suppression wiring terminal (106) and an explosion-suppression multi-core wall-crossing wiring terminal (107); the explosion-suppression observation window (104) is arranged on the side wall of the main cavity (101); the cable entry (105) is arranged inside the wiring cavity (102); the explosion-suppression wiring terminal (106) is arranged at a connection part between the main cavity (101) and the wiring cavity (102); and the explosion-suppression multi-core wall-crossing wiring terminal (107) is arranged at a connection part between the main cavity (101) and the battery cavity (103). When an emergency occurs and a mining alternating-current power supply is in failure, the power system can still output electric energy for providing guarantee for the escape of the underground operating personnel of the coal mine and the rescue work. The power system is suitable for being selected and used for various loads, is convenient to use and is safe and reliable due to an intrinsically safe output mode.

Description

Technical field [0001] The invention relates to the technical field of power supplies, and in particular to a large-capacity explosion-proof uninterruptible power supply system. Background technique [0002] Potential safety hazards in coal mines, such as floods, fires, gas and coal dust explosions, and roof fall, threaten the lives of miners all the time. Due to the harsh environment in coal mines, it is very difficult for underground workers to escape and avoid danger. In the prior art, the capacity of the uninterruptible power supply used in underground coal mines is 5-20 AH. When an emergency occurs, the uninterrupted power supply of the prior art is far from being able to meet the escape needs of underground coal mine operators. [0003] At present, there is a great need for a large-capacity explosion-proof uninterruptible power supply. Summary of the invention [0004] The purpose of the present invention is to provide an explosion-proof cavity for a large-capacity explosio...
