誘導加熱電源とマッチングトランス

In today’s rapidly advancing technological era, the efficient transmission and conversion of electric power have become continuous goals pursued across various industries. Magnetic levitation transformers, as an emerging type of electrical equipment, are gradually demonstrating their unique advantages and broad application potential. This article will thoroughly explore the application fields of magnetic levitation transformers, analyze their technical characteristics and future development tren

1. Transformer Major Overhaul Cycle The main transformer shall undergo a core-lifting inspection before being put into service, and thereafter a core-lifting overhaul shall be performed every 5 to 10 years. Core-lifting overhaul shall also be carried out if a fault occurs during operation or if issues are identified during preventive tests. Distribution transformers operating continuously under normal load conditions may be overhauled once every 10 years. For on-load tap-changing transformers, t

Preparatory Work Before Adjusting the Tap Changer of H61 Oil Power 26kV Electric Transformer Apply for and issue a work permit; carefully fill out the operation ticket; conduct a simulation board operation test to ensure the operation is error-free; confirm the personnel who will carry out and supervise the operation; if load reduction is required, notify affected users in advance. Before construction, power must be disconnected to take the transformer out of service, and voltage testing must be

1. 農業用H59/H61油浸配電変圧器の損傷原因1.1 絶縁損傷農村の電力供給では一般的に380/220V混合システムが使用されている。単相負荷の割合が高いことから、H59/H61油浸配電変圧器はしばしば著しい三相負荷不平衡状態で運転される。多くの場合、三相負荷不平衡の程度が運転規程で許容される限界を大きく上回っており、巻線絶縁の早期老化、劣化および最終的な破壊を引き起こし、焼損に至る。H59/H61油浸配電変圧器が長期間の過負荷、低圧側ライン故障、または急激な大負荷増加に見舞われた際、低圧側に保護装置が設置されておらず、かつ高圧側のドロップアウトフューズが適切に（あるいは全く）作動しない場合、変圧器は定格電流を大幅に超える故障電流（時には定格の数倍）を長時間強制的に流すことになる。これにより温度が急激に上昇し、絶縁の老化が加速され、最終的に巻線が焼損する。長期間の運転後、H59/H61油浸配電変圧器のゴムビーズやガスケットなどの密封部品は老化・ひび割れを起こし、効力を失う。これを検知して適時に交換しなければ、油漏れおよび油面低下が生じる。空気中の湿気が大量に絶縁油に侵入し、その誘電
