the high-voltage chamber of the European-style box-type transformer is generally composed of high-voltage load switches, high-voltage fuses and arresters. the low-voltage room is composed of a low-voltage air switch, a current transformer, an ammeter, and a voltmeter.
the electrical equipment components in the European-style box-type transformers are all selected from stereotyped products, and the technical performance of the components meets the corresponding standard requirements. In order to reliably realize the five-proof requirements, mechanical interlocking is adopted between each electrical component, and each electrical component is installed on a structure with sufficient strength and rigidity to facilitate the connection of wires. the operation adopts electric mode, no need for additional power supply, it can be led out by TV.
in addition, European-style box transformers also have the functions of electric energy detection, display, and measurement, and can achieve corresponding protection functions. They also have special grounding conductors and have obvious grounding signs. In addition, in order to adapt to the outdoor working environment, the shell top of the European-style box-type transformer generally adopts a partition structure, which is equipped with thermal insulation materials. In order to ensure the normal heat dissipation of electrical equipment, it has measures such as rainproof, dustproof, and preventing the entry of small animals.
