An easy-to-maintain transformer

Abstract

The invention relates to a transformer which is convenient for maintenance, comprising a bracket fixedly connected to a utility pole, an iron core fixedly connected to the bracket, and a casing disposed outside the iron core and slidably connected with the bracket. The transformer also includes a lifting device, which is respectively connected with the bracket and the casing, and adjusts the casing to move up and down, thereby exposing the iron core. The beneficial effects of the present invention: by using the gear transmission mechanism and the connecting rod mechanism, the transformer does not need to lift the iron core of the transformer during maintenance, but lowers the casing of the transformer through transmission, which is convenient for maintenance, and is installed under the iron core of the transformer. The filter screen with scraper allows the scraper to scrape off the impurities on the inner wall of the shell when the shell is lowered, and uses the filter screen to filter the oil inside the shell to ensure that the oil is clean.

Description

technical field [0001] The invention belongs to the field of power components, and in particular relates to a transformer which is convenient for maintenance. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core. The main functions are voltage transformation, current transformation, impedance transformation, isolation and voltage regulation, etc. The circuit symbol is usually T when as the beginning of the number. In recent years, with the continuous and rapid growth of the power industry, the use of transformers is also increasing, but the following problems often occur when repairing transformer cores: [0003] 1. Because the transformer core is large and heavy, it is difficult to move after being fixed, causing inconvenience to maintenance; [0004] 2. Since the transformer core is cooled by oil, it needs to b...

Problems solved by technology

[0003] 1. Since the iron core of the transformer is large and heavy, it is difficult to move after being fixed, causing inconvenience to maintenance;

[0004] 2. Since the transformer iron core is cooled by oil, it needs to be soaked in oil, so after a long time of use, there will be many impurities in the oil, which will affect the cooling and insulation effect of the oil.
