Embodiment Construction

[0016] in the only figure 1 In general, the symbol indicates the battery-powered device used in underground mining. In the illustrated embodiment, the battery-powered device comprises a voltage-resistant battery compartment 1 and a side or additional housing 2 . The battery box 1 includes a battery box 3, and a lithium-ion battery 5 is housed in its installation cavity 4, and the lithium-ion battery is preferably composed of a plurality of lithium-ion batteries connected in series. The battery box 3 is pressure-resistant closed with a battery box cover 6 , for example by means of a plurality of screws 7 schematically indicated in the drawing, through which a lithium-ion accumulator can be inserted into the installation chamber 4 . The wall thicknesses of the boundary walls of the battery box 3 and the cover 6 as well as the screws 7 are designed such that the battery box 1 remains pressure-tight and gas-tight even when the interior 4 explodes at a certain maximum explosion pr...

Abstract

An intrinsically-safe battery power supply for electrical equipment in underground mining and in other areas exposed to the danger of explosion is disclosed. The power supply includes at least one chargeable storage battery cell disposed in a battery housing. At least one storage battery cell comprises a chargeable lithium storage battery cell and the battery housing is configured to be pressure-resistant and to receive all lithium storage battery cells in a manner so as to be protected from explosion. The pressure-resistant configuration of the battery housing enables the use of lithium storage battery cells in underground mining. Once the battery power supply fulfils all requirements of ignition protection certification, even modern types of lithium storage battery cell can be disposed in the battery housing.

Description

technical field [0001] The present invention relates to a safe self-control type battery power supply device for electrical equipment in underground mining and other areas with explosion or mine gas explosion hazards, comprising at least one rechargeable accumulator housed in a battery box. Background technique [0002] In underground mining and in other areas where there is a risk of explosion or mine gas explosion, it is required to supply electrical equipment with sufficient safe self-controlled voltage independently of the feeder network. For example, in underground mining, in the column withdrawal controller, in the remote control, for measuring instruments in inaccessible parts, and for other electrical equipment, rechargeable battery-powered devices are used, which use nickel-cadmium batteries (NiCd Battery). Nickel-cadmium batteries have a small charge capacity and poor recharging performance, because if the NiCd battery is not fully discharged before recharging, it...
