Process principle

The core is made of Shanghai Baosteel 30P105 and 120 high-quality cold-rolled ferrite cores, 45-degree stepped full-oblique seam structure, with the help of three-shear and two-punch core cornering and cross-cutting processing technology and five-step stepper motor shearing and stacking process, the magnetic flux at the interface is optimized and the seismic energy of the core is reduced. The core carries out the sealing process of integrated dry solid and surface insulating resin, which effectively reduces the no-load loss and full-load flow core noise.

The high-voltage ignition wire is made of high-quality F-class insulated transmission line coil inductor, and the large-volume electromagnetic coil is equipped with a heat exhaust gas pipe along the radial direction. This structure has good resistance to current impact, temperature change, cracking and excellent thermal conductivity. It adopts a multi-level segmented barrel structure, which has a strong overpressure bearing capacity and a very low partial discharge level. The solenoid coil is cast after vacuum drying, and the whole process of pouring and solidification is carried out in accordance with the pre-programmed process curve diagram, and the accurate process management ensures that the solenoid coil has no air holes and cavitation.

At the same time, the foil coil will not have the number of radial coil turns and the inductance helix angle of the radial coil, which effectively avoids the radial force of the transformer during the short circuit, and ensures that the current intensity in the electromagnetic coil can also be adjusted freely along the radial direction according to the load of the high-voltage ignition line, which reduces the axial force during the sudden short circuit of low voltage. The top of the solenoid coil after the coil inductor is sealed with epoxy resin to prevent the addition of various dirt and moisture.
