technical field

The invention relates to the technical field of power equipment maintenance, in particular to a transformer maintenance platform.

Background technique

Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.).

With the sustained, healthy and rapid development of China's economy, the demand for electricity continues to grow rapidly. In 2011, the electricity consumption of the whole society was 4.69 trillion kwh, an increase of 11.7% over the previous year, and the consumption demand was still strong. Per capita electricity consumption was 3483 kWh, an increase of 351 kWh over the previous year, exceeding the world average. In recent years, my country's electricity demand has grown rapidly, and the high-speed construction of the power grid has stimulated the market demand for power transmission and transformation equipment. As the key electrical equipment for power transmission, the market demand for transformers has also maintained a steady growth. At the same time, the large demand for transformers will inevitably lead to a large number of maintenance and hoisting work for transformers.

At present, when the transformer is overhauled, it is often necessary to hoist the transformer from the pole. In order to quickly overhaul the transformer in rainy days, the transformer needs to be transported to the overhaul workshop to complete, which greatly reduces the overhaul efficiency of the transformer. Sometimes it can seriously affect production and life. Therefore, it is necessary to provide a maintenance platform capable of hoisting the transformer on the spot.
