Abstract

The invention provides an oil-immersed circuit breaker, which comprises a base. The base is provided with a moving contact support. The moving contact support is hinged by a moving contact. The base is provided with a mechanism support. The mechanism support is hinged by a lever. A tripper and a locker are arranged behind the lever in sequence; the lever can drive the tripper to rotate; the bottom portion of the locker is provided with a traction rod capable of moving longitudinally; the front end of the moving contact is provided with a moving contact supporter; a contact point of the moving contact is arranged on a contact point installation frame; and the contact point installation frame is in slip fit with the moving contact supporter, and a reset member is arranged between the two. Through the arrangement of the moving contact supporter and the contact point installation frame, wherein the contact point installation frame is in slip fit with the moving contact supporter, and the reset member is arranged between the moving contact supporter and the contact point installation frame, and by arranging the reset member between the contact point installation frame and the moving contact supporter, the moving contact is allowed to have high disconnecting performance; meanwhile, the elastic force of the reset member can reduce temperature rise caused when the moving contact makes a contact with a static contact, thereby improving service life thereof; and the reset member can achieve a subsection speed controlling effect.

Description

technical field [0001] The invention belongs to the technical field of circuit breakers, and in particular relates to an oil-immersed circuit breaker. Background technique [0002] Complete self-protection technology is a protection system for distribution transformers. The fully self-protecting system protects the transformer from lightning strikes, secondary faults, severe overloads and provides visual alarms for abnormal loads. Fully self-protected technology allows transformer manufacturers to produce high-performance distribution transformers, reducing the operation and maintenance problems associated with traditional transformers. [0003] A fully self-protected design provides maximum protection against transformer faults and disruptive outages, while avoiding additional costs associated with complex installations, unnecessary equipment and outages. [0004] The oil-immersed low-voltage circuit breaker is the core component of complete self-protection technology. It...
