Elevator power generation device

Abstract

The invention provides an elevator power generation device which comprises a circuit controller, a power generator, a spoke and a transformer. The spoke is fixed to a rotation shaft of the power generator, the power generator and the spoke are fixed to a telescoping device, the telescoping device is electrically connected with the circuit controller and controlled by the circuit controller, the output end of the power generator is connected with a power grid through the transformer, the transformer comprises a base and a box body, the transformer box body is arranged at the top of the base, a ventilation opening is formed in one side of the box body, a transformer body consisting of an iron core and a winding coil is arranged in the box body, and a heat dissipating mechanism is arranged on the inner wall of the box body and rightly faces the ventilation opening. A ventilation cover is arranged on the ventilation opening, and the ventilation opening is movably connected with the ventilation cover. The heat dissipating mechanism of the transformer of the elevator power generation device rightly faces the ventilation opening. The ventilation opening is provided with the ventilation cover and is movably connected with the ventilation cover. When heat dissipation is needed, the ventilation cover movably connected with the ventilation opening is removed, the heat dissipating mechanism rightly faces the ventilation opening, and a remarkable heat dissipation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator power generation device. Background technique [0002] Thermal design of sealed module power supplies is usually a very difficult subject, especially for transformers. The sealed module power supply usually uses heat conduction to dissipate heat. Because the potting glue inside the module usually cannot completely wrap the transformer, and the thermal resistance of the transformer core is relatively large, especially at the joint surface of the core, the side of the transformer attached to the substrate The temperature difference between the bottom core and the top temperature on the other side is very large, and it is necessary to conduct heat from the top core to the substrate. The main components of the transformer are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion,...
