Abstract

The invention provides a transformer insulating sheath, which relates to the technical field of insulating sheaths. The transformer insulating sheath includes a first sheath shell and a second sheath shell, and the first sheath shell and the second sheath shell The side of the body is provided with a fixed bead, the side of the fixed bead is fitted with a fixed plastic nail, the sides of the first sheath shell and the second sheath shell are provided with a bending bar, and the first sheath The bottom surface of the shell and the second sheath shell is provided with a wire clamp shell, the bottom surface of the wire clamp shell is provided with a fixed sleeve, and the top surface of the first sheath shell and the second sheath shell is provided with a There is an outlet sleeve, and the top surface of the outlet sleeve is provided with an outlet sleeve reinforcement ring. The use of non-vertical insulating sheath housings is adapted to non-horizontal outlet terminals, which improves the safety of use. Replaceable plastic nails are used to fix the housings to improve service life. The bendable insulating sheath housings are used. , so that maintenance can be carried out without removing the insulating sheath.

Description

technical field [0001] The invention relates to the technical field of insulating sheaths, in particular to transformer insulating sheaths. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: power transformers and special transformers. The terminals of the transformers are directly exposed in the air, which is easily corroded by acid rain and salt spray or threatened by artificial electric theft, electric shock, and foreign objects. Protection is directly related to life safety and production safety. [0003] When the applicant applied for the present invention, after searching, it was found that the Chinese patent disclosed ...
