Abstract

The invention belongs to the field of transformers, particularly relates to a control transformer for a low-consumption and energy-saving elevator, and aims to solve the problems that the service life of an existing transformer is shortened due to the fact that the existing transformer lacks an effective heat dissipation device and is poor in heat dissipation effect. The control transformer comprises a shell and a transformer body, a first mounting cavity and a second mounting cavity are formed in the shell, an annular sliding groove is formed in the inner wall of the bottom of the first mounting cavity, a sliding ring is slidably mounted in the annular sliding groove, a placement plate is fixedly connected to the top of the sliding ring, and the transformer body is arranged at the top of the placement plate. The transformer body can be subjected to larger-area and more comprehensive air blowing heat dissipation, the situation that the transformer body is covered by dust to affect heat dissipation of the transformer body is avoided, meanwhile, cleaning can be conducted on a second dustproof net plate, the situation that the second dustproof net plate is blocked to affect airflow flowing, and consequently the heat dissipation efficiency is reduced is avoided, and the service life of the transformer body is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a control transformer for low-consumption and energy-saving elevators. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or less than 15° from the plumb line. There are also stepped, step boards It is installed on the crawler and runs continuously, commonly known as escalator or moving walk. When the elevator is running, it needs a transformer to control it. The transformer will heat up during work, causing the temperature of the transformer to rise. If the temperature is too high, it will affect the service life and use effect of the transformer; [0003] However, the existing transformer lacks an effective heat dissipation device, and the heat dissipation effect is poor, resulting in a reduced...
