Abstract
An electrical power unit is provided particularly for use in underground mining insulations, where fire risks are especially serious. An electric generator (42) is driven by an hydraulic motor (41), each of which is in a flameproof housing. A regulator (45) includes circuitry for limiting current supplied by the generator (42), and fluorescent light units (46) are connected to the regulator by cables (47). The hydraulic motor (41) may with advantage be connected directly to the hydraulic circuit of a mining machine such as, for example, a powered roof support. The power unit and light units may be housed integrally within a powered roof support, to provide light at a coal face, in a safe and reliable manner.
