Description

Insulating binding and shaping mould for current transformer

Technical Field

The utility model belongs to the technical field of current transformer, especially, relate to a shaping mould is wrapped in current transformer insulation.

Background

As is well known, transformers are also called instrument transformers and are the general names of current transformers and voltage transformers. The high voltage can be changed into low voltage, and the large current can be changed into small current for measuring or protecting the system. Its function is mainly to convert high voltage or large current into standard low voltage (100V) or standard small current (5A or 1A, both referring to rated value) in proportion so as to realize standardization and miniaturization of measuring instrument, protection equipment and automatic control equipment. Meanwhile, the mutual inductor can be used for isolating a high-voltage system so as to ensure the safety of people and equipment.

At present, in the insulation wrapping stage of the mutual inductor, if the situation that the inner diameter of a solenoid is small and the height of the solenoid is high is met, a common roll-shaped adhesive tape is not easy to operate, and a long shuttle is needed to be used for insulation wrapping of the solenoid. The existing shuttle tool needs to manually pour the rolled sticky tape on the long-strip epoxy plate, which wastes time and labor.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

a current transformer insulation wrapping shaping mould comprises a horizontal workbench; the upper surface of the horizontal workbench is provided with:

a primary terminal fixing base (1) for fixing the primary terminal; a plurality of bolt holes in the horizontal direction are formed in the primary terminal fixing seat (1);

a positioning column (2) for positioning the primary copper strip; the number of the positioning columns (2) is four, and the four positioning columns (2) form a rectangular frame in an enclosing mode;

a central primary fixing table (3) for fixing the primary long neck portion; the central primary fixing table (3) is positioned between the primary terminal fixing seat (1) and the positioning column (2).

Preferably: the horizontal workbench is a steel plate (5).

Preferably: also comprises a movable cushion block (4) for adjusting the height of the primary copper strip.

Preferably: and a plurality of jacks for inserting the positioning columns (2) are formed in the horizontal workbench.

Preferably: the primary terminal fixing seat (1) comprises two rectangular blocks, and four bolt holes are formed in each rectangular block.

Preferably: the central primary fixing table (3) is of a U-shaped structure.

The utility model has the advantages that:

through adopting above-mentioned technical scheme, can use this current transformer insulation to wrap integer mould and wrap and shape in insulation wrapping and transportation stage, fix at package frame key position, the insulation wrapping stage can be according to the demand plug reference column at any time, wraps and carries out the solid type after accomplishing, guarantees insulation distance and whole solenoid symmetry.
