Title:
REACTOR HAVING OVERVOLTAGE SUPPRESSION FUNCTION AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/018969
Kind Code:
A1
Abstract:
A reactor having an overvoltage suppression function and a manufacturing method therefor. The reactor comprises wire coils, the wire coils comprising a first coil and a second coil, the first coil and the second coil being connected in series, and both ends of the second coil are provided in parallel with guard gaps; when the voltage of the second coil reaches a breakdown voltage of the guard gaps, the guard gaps are broken down to lower the voltage of the reactor. The manufacturing method comprises the following steps: fastening an insulation sleeve on the outer side of an iron core; wrapping high voltage cable paper on the insulation sleeve; winding a first coil; winding a second coil; and connecting the guard gaps and the second coil in parallel. The reactor utilizes the principle of electromagnetic induction, and the guard gaps are additionally provided in an original reactor; when the reactor bears a relatively large voltage, discharge protection is performed, so as to lower the voltage of the reactor, thereby protecting the reactor in a timely manner, and preventing the reactor from being burned and damaged, and the parallel configuration of the guard gaps implements more convenient installation and replacement.
