Title: Tsuyoshi Sekiguchi: Innovator in Electronic Overload Relay Technology

Introduction

Tsuyoshi Sekiguchi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of electronic overload relay technology, holding a total of 4 patents. His innovative designs have enhanced the functionality and reliability of electrical systems.

Latest Patents

One of his latest patents is an electronic overload relay that features a magnetic circuit comprising a stationary iron core, a permanent magnet, and an armature arranged in a circular pattern. This design includes a contact mechanism spring that separates the armature from the stationary iron core, allowing the magnetic circuit to open and switch the contact mechanism to a reset position. When an overload is detected, a coil on the magnetic circuit generates a magnetic flux in the same direction as that of the permanent magnet. After a predetermined time, the magnetic flux reverses direction, facilitating the reset process.

Another significant patent is for an overload relay and its operating method. This invention includes a trip capacitor that stores an electric charge to excite a trip coil, thereby interrupting the current flow between a power source and a load. Additionally, a reset capacitor is utilized to reset the tripped current flow. The design also features an energizing unit that powers the coils and a capacitor-diagnosing unit that assesses the condition of the capacitors. This innovative approach ensures that the trip coil is forcibly energized when degradation of the trip capacitor is detected.
