Product Description

on-Load Tap Changer for Transformer Load Break Switch Tap Changer


The structure of SV on-load tap-changer

Compared with other products, we made some improvements as follows:

1. Change the selector

At present, the domestic products still use the old foreign structure, i. E., the movable contact makes connection with the fixed contact. This structure has a large torque. Our company switched over to the traditional docking structure with good contacts and small torque. The insulation bracket is made from three isolated wall with a high-to-ground withstand voltage.

2. Under flange improvement

The under-flange s made of engineering plastics and lifted by four screws. While in the accidents, the increased pressure often damage the under-flange (it occurs at home and abroad ). Therefore, our company strengthens the prone-to-crack place to ensue good strength.

3. Correct arc principle

Some domestic manufacturers apply with slide between are contact and rotating pole. When the arc contact leaves from the fixed contact, the current will breaks, and the current passes through arc contact to the rotating rod. As the gap between the two can only connect by the arc, the rotating rod will burn off and the gap will get larger, resulting in the broken of the rotating poles, thus accidents arise. We considered of this and take appropriate measures

4. Correct resistance installation

Products of the same kind at home and abroad have no outer resistance baffle. Resistance will be scattered in accidents. Under the effect f elasticity, it collapses which cause the tapping short circuit and threaten the safety of the transformer. We add one baffle at the outer layer of resistances as a preventive measure, enhancing the reliability.
