Transformer incoming and outgoing line wiring connection protection device

Abstract

The invention discloses a transformer incoming and outgoing line wiring connection protection device. According to the technical scheme, the transformer incoming and outgoing line wiring connection protection device is characterized by comprising a transformer body, a fixing plate is fixedly connected to the top of the transformer body, a through groove is formed in the fixing plate, a lifting structure is arranged on the fixing plate, and two supporting plates are arranged at the top of the lifting structure; the opposite sides of the two supporting plates are both sleeved with movable plates, and semicircular covers arranged at equal intervals are inserted into the two movable plates in a penetrating mode. After being expanded, the semicircular air bags get close to the opposite ends of the incoming and outgoing lines along the supporting ring until the two semicircular covers are in contact with each other, at the moment, the semicircular air bags are in contact with each other, and the two semicircular air bags are tightly attached to the opposite ends of the incoming and outgoing lines respectively; therefore, the influence of rainwater and dust on the connection position of the incoming line and the outgoing line is effectively avoided, and the service life of the line is further prolonged.

Description

technical field [0001] The invention relates to the technical field of transformer protection, and more specifically, to a protection device for connection connection of incoming and outgoing wires of a transformer. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. [0003] When the existing transformer is connected to the line, the line protrudes from the top of the transformer and then connects to the external equipment. However, when the line protrudes from the top of the transformer, there is usually no protective structure, resulting in a gap between the line and the outlet hole of the transformer. It is easy to wear and tear between the lines, resulting in a short service life of the line, and the connection position of the incoming and outgoing lines cannot be protected. Rain and dust will a...

[0003] When the existing transformer is connected to the line, the line protrudes from the top of the transformer and then connects to the external equipment. However, when the line protrudes from the top of the transformer, there is usually no protective structure, resulting in a gap between the line and the outlet hole of the transformer. It is easy to wear and tear between the lines, resulting in a short service life of the line, and it is impossible to protect the connection position of the incoming and outgoing lines. The rain and dust will accelerate the aging of the connection position of the incoming and outgoing lines and cause leakage. Therefore, a protection device for the connection of the incoming and outgoing lines of the transformer is needed.
