High-IP-protection-level voltage transformer capable of being used for gas-insulated high-voltage switch cabinet

Abstract

The invention discloses a high-IP-protection-level voltage transformer capable of being used for a gas-insulated high-voltage switch cabinet. The voltage transformer comprises a voltage transformer body, an iron core, a primary conductor and a primary winding are arranged in the voltage transformer body. The primary conductor is positioned on one side of the iron core; wherein the primary windingis located on the iron core column, the upper end of the voltage transformer main body is provided with an installation aluminum plate, the lower end of the voltage transformer main body is provided with an installation steel plate, one side of the voltage transformer main body is provided with a secondary junction box, and one side of the secondary junction box is provided with a secondary lead.According to the high-IP-protection-level voltage transformer capable of being used for the gas-insulated high-voltage switch cabinet, the voltage transformer is provided with the epoxy resin and themetal shielding net, the protection grade reaches up to IP67, the equipment can normally work underwater for at least 30 minutes, the equipment can be normally put into operation after being soaked inwater and dried, the shielding net arranged inside the voltage transformer can enable the voltage transformer to achieve the safe and touchable function, and better use prospects are brought.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a voltage transformer with a high IP protection level that can be used in a gas-insulated high-voltage switchgear. Background technique [0002] The voltage transformer is a key functional device used to realize the measurement and protection of the power supply system. In order to ensure the safe and normal operation of the power supply system in areas that are often hit by floods, it is necessary for high-voltage switchgear, including voltage transformers, and other equipment to have a higher protection level. And safe use requirements, with the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of voltage transformers. [0003] There are certain disadvantages in the use of existing voltage transformers. First of all, the safety function of traditional transformers needs to be strengthened. It has brought some ...
