Abstract

The invention discloses a dual-opening magnetic circuit iron core device body clamping device used for electrical equipment. The device has a high-voltage upper clamping piece, a low-voltage upper clamping piece, a high-voltage lower clamping piece, and a low-voltage lower clamping piece made of a high-strength nonmetal insulating material. The high-voltage upper clamping piece, the low-voltage upper clamping piece, the high-voltage lower clamping piece, and the low-voltage lower clamping piece are connected together through a plurality of horizontal pulling screws and a plurality of verticalpulling screws, to form a rigid frame structure. The dual-opening magnetic circuit iron core device body clamping device used for electrical equipment adopts a nonmetal material as clamping components, and the screws on horizontal and vertical directions are used to form the rigid frame structure to clamp an iron core and a device body. In a device body leakage magnetic field environment, no lossis generated, and the device has enough mechanical strength and can satisfy clamping requirements of a dual-opening combined iron core device body. On the other hand, the clamping components in the structure can be designed in an adjusting manner according to size variation of a dual-opening combined iron core, and adaptability is good.

Description

technical field [0001] The invention relates to the field of electric equipment manufacturing, in particular to a double-opening magnetic circuit iron core body clamping device for electric equipment. Background technique [0002] At present, in power equipment, such as transformers and reactors, the clamping parts of the iron core body are made of steel materials, such as channel steel, which are used to clamp the iron core and compress the body coil; for example, the existing In the technology, the clamping method for the three-phase laminated iron core is to clamp through channel steel metal clamps (see the attached manual for details). Figure 8 ). [0003] Although steel structural parts have the advantage of good strength, their disadvantages are also very prominent. For example, in the leakage field of the iron core body, eddy current loss will be induced on the steel structural parts, which will cause local temperature rise and may damage the surrounding insulation. ...
