Problems solved by technology

[0004] The disadvantages of this structure are: 1. The ship shape and wave deformation of the cover plate are relatively large during the processing, especially for low-voltage distribution transformers with magnetic isolation plates; 2. In order to reduce the ship shape deformation, the cover plate is temporarily strengthened by weldin

Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0018] Such as figure 1 , figure 2 As shown, a distribution transformer cover plate includes a square cover plate body 1, the upper cover surface 11 of the cover plate body 1 is a flat end surface, and each of the four sides of the cover plate body 1 is extended by 60 mm as ribs 13. The four corners of the side 13 are respectively provided with a gap 12, and the front 30mm of the four ribs 13 are bent inwardly to 90° to form an edge, and the gap 12 is a gap of 30mm×30mm.

[0019] The process steps of preparing the cover plate of the present invention are as follows,

[0020] First, prepare the main body 1 of the cover plate by cutting the material according to the size of the cover plate drawing ----- punch out 30mm×30mm gaps at the four corn...

Abstract

The invention discloses a distribution transformer cover plate which relates to the technical field of transformer devices. The distribution transformer cover plate comprises a square cover plate body and is characterized in that the upper cover surface of the cover plate body is a flat end surface, four sides of the cover plate body respectively extend by 60mm to be used as flanges, four corners of the flanges are respectively provided with a gap, and front 30-mm parts of the four flanges are inwards bent to form included angles of 90 DEG, so that edges are formed. The distribution transformer cover plate is flat, and is little in deformation of boat shape and waves, attractive in appearance and little in labor intensity; a temporary reinforcing rib is not needed to be welded or the thickness of a steel plate is not needed to be increased. The contact surface of the distribution transformer cover plate and a box edge sealing member is flat, the compression amounts of sealing members are consistent, and the leakage probability is reduced.

Description

technical field [0001] The invention relates to the technical field of transformer equipment, in particular to a distribution transformer cover plate. 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. When the primary winding is supplied with alternating current, alternating magnetic flux is generated, and the alternating magnetic flux induces an alternating electromotive force in the secondary winding through the magnetic conduction of the iron core. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns. The main function is to transmit electric energy, therefore, the rated capacity is its main parameter. Rated capacity is a customary value for expressing power. I...
