- 膨張室を備えつつ油で絶縁された変圧器、チョークコイル又はシーケンススイッチ用であり吸湿材で満たされた除湿装置の乾燥方法であって、該除湿装置が吸入パイプを介して前記膨張室に接続されており、前記吸湿材が電気ヒータで加熱されることにより乾燥されるとともに再生され、前記電気ヒータによる加熱が、前記膨張室内の空気が流入しない場合にのみなされる前記乾燥方法において、
(1)複数の所定の時間間隔に分割された1サイクル(a)を設定し、
(2)前記所定の時間間隔の開始時点(th)での前記吸入パイプにおける温度(θ1)及び同終了時点(th+1)での前記吸入パイプにおける温度(θ2)をそれぞれ測定するとともに、これらの差(θ2−θ1=dθ)を計算して温度勾配(dθ/dt)を算出し、
(3)該温度勾配の算出を前記1サイクル(a)繰り返すとともに、これを複数サイクル(a=1,a=2,...a=x−1)行って、前記温度勾配が0以上となった時間間隔をメモリし、
(4)前記複数回のサイクルを行った直後のサイクル(a=x)において、これら複数回のサイクルに共通の前記温度勾配0以上の時間が所定時間(z)以上あるか判断し、所定時間時間以上あれば、この複数回のサイクルを行った直後のサイクルにおける前記共通の時間の開始時点から前記電気ヒータを作動させ、
(5)一方、所定時間に満たないのであれば、更にもう1サイクル(a=x+1)について上記(2)〜(4)を行う
ことを特徴とする除湿装置の乾燥方法。 - 前記1サイクル(a)を1日(24時間)としたことを特徴とする請求項1記載の除湿装置の乾燥方法。
- 前記複数回のサイクルを3回としたことを特徴とする請求項1又は2記載の除湿装置の乾燥方法。
- 前記所定時間(z)を4時間としたことを特徴とする請求項1〜3のいずれか1項に記載の除湿装置の乾燥方法。
- 湿度センサにより湿度を測定し、該湿度センサが湿度の限界値の超過を信号化したときのみ前記電気ヒータを作動させることを特徴とする請求項1〜4のいずれか1項に記載の除湿装置の乾燥方法。
- 前記複数回のサイクルにその直後のサイクルを足したサイクル数(x)より多いサイクル数を寿命に設定し、該寿命を経過後は、前記温度勾配及び湿度に関係なく、いかなる場合にも前記電気ヒータを作動させることを特徴とする請求項1〜5のいずれか1項に記載の除湿装置の乾燥方法。
