Problems solved by technology

In the case of uncertain factors, the external power supply will drop to about AC260V instantaneously, resulting in a power failure phenomenon. At this time, the transformer in the control system of the escalator will fail due to the reduction of the input voltage, and the equipment will not work normally.
If a person is riding an escalator, a sudden power failure occurs, which will affect the personal safety of the person, and may even cause a personal accident

Abstract

The invention discloses a power supply system of an escalator, which comprises a power supply control module and a frequency conversion module, wherein the frequency conversion module is electrically connected with the power supply control module, the power supply control module comprises two sets of transformers with secondary ends connected in parallel, and a change-over switch used for switching between the two sets of transformers, the two sets of transformers are a transformer for supplying power to an external power supply and a transformer for supplying power to an uninterrupted power supply respectively. After the adoption of the technical scheme, the power supply system of the escalator has the benefits as follows: the escalator can not be stopped under the condition of power supply flashing, the work of the escalator is guaranteed to be smooth, meanwhile, the safety of personnel riding the escalator can be ensured, and safety accidents can be effectively avoided.

Description

technical field [0001] The invention relates to an escalator power supply system, in particular to a power supply system in which the escalator does not stop when the power supply flashes off. Background technique [0002] In the prior art, the control system of the escalator is equipped with a set of transformers, the external power supply is AC380V, the external power supply is input to the primary of the transformer, and the secondary output of the transformer is AC220V, AC24V and DC24V. In the case of uncertain factors, the external power supply will drop to about AC260V instantaneously, resulting in a power failure phenomenon. At this time, the transformer in the control system of the escalator will fail due to the decrease of the input voltage, and the equipment will not work normally. If a person is riding an escalator, a sudden power failure occurs, which will affect the personal safety of the person, and may even cause a personal accident. Contents of the inventio...
