技術分野 Technical field
この発明は、 一般的に UP S (Un i n t e r r up t i b l e Powe r Sy s t ems) と称される無停電電源装置に関し、 特に、 バッテリ寿命によ るバッテリパックの交換のために、 ノくッテリパックがコネクタによって電源制御 部に交換可能に導電接続される型式の無停電電源装置に関するものである。 背景技術  The present invention relates to an uninterruptible power supply generally referred to as UPS (Uninterruptible Power System), and in particular, to replace a battery pack due to battery life, a battery pack is connected to a connector. The present invention relates to an uninterruptible power supply of a type that is conductively connected to a power supply control unit in a replaceable manner. Background art
停電時に、 パーソナルコンピュータ用などの負荷に電力を継続供給する無停電 電源装置 （UPS) は、 多くの場合、 バックアップ電源 （バッテリパック） とし て、 繰り返し充電可能なシールド鉛電池が使用されており、 この種の無停電電源 装置は、 たとえば、 日本国特許庁公開特許公報 （特開平 4 - 28 68 62) に示 されている。  Uninterruptible power supplies (UPS) that continuously supply power to loads such as those for personal computers in the event of a power outage often use shielded lead batteries that can be repeatedly charged as backup power (battery packs). This type of uninterruptible power supply is disclosed, for example, in the Japanese Patent Office Patent Publication (JP-A-4-2868662).
シールド鉛電池等の 2次電池は、 経時劣化し、 使用年数によってバックアップ 可能時間が短縮されてくるから、 通常、 2〜3年を目安にしてバッテリパックを 交換することが推奨されている。  Secondary batteries, such as shielded lead batteries, deteriorate over time and the backup time is shortened depending on the number of years of use. Therefore, it is usually recommended to replace the battery pack every two to three years.
このようなことから、 多くの無停電電源装置では、 ノ テリ寿命によるバッテ リパックの交換のために、 バッテリパックがコネクタによって電源制御部に交換 可能に導電接続されるようになっている。  For this reason, in many uninterruptible power supplies, the battery pack is connected to the power supply control unit in a replaceable conductive manner in order to replace the battery pack due to the life of the battery.
バッテリパックの充電中は、 電源制御部よりバッテリパックへ充電電流が流れ ており、 特に、 バッテリパックの電荷量が少ない場合には、 比較的大きい充電電 流が流れているから、 この状態時にバッテリパックが外されると、 電源制御部と バッテリパックとの導電接続部であるコネク夕部分にアークが発生し、 コネクタ の溶融、 溶着により、 コネクタが早期破損し、 コネクタの交換も必要になる。 また、 停電時の前記 くッテリパックによるバックアツプ電源供給中には くッテ リパックより電源制御部へバックアップ電流が流れているから、 この状態時にバ ッテリパックが外されると、 バックアップ電源供給が中断され、 無停電電源供給 が行われなくなる。 そしてこの場合も、 コネクタ部分にアークが発生し、 コネク 夕の溶融、 溶着によりコネクタが早期破損し、 コネクタの交換も必要になる。 このコネクタの交換は、 簡単なバッテリパックの交換とは異なり、 U P Sの動 作信頼性確保の観点から、 ユーザサイドでは行われ難い。 During charging of the battery pack, the charging current flows from the power supply control unit to the battery pack. In particular, when the charge amount of the battery pack is small, a relatively large charging current flows. When the pack is removed, an arc is generated in the connector area, which is the conductive connection between the power control unit and the battery pack, and the connector is melted and welded, causing the connector to be damaged at an early stage and requiring replacement. In addition, during the backup power supply by the battery pack at the time of power failure, the backup current flows from the battery pack to the power control unit.If the battery pack is removed in this state, the backup power supply is interrupted. The uninterruptible power supply will not be performed. Also in this case, an arc is generated in the connector part, and the connector is damaged at an early stage due to melting and welding of the connector, and the connector needs to be replaced. Unlike the simple battery pack replacement, this connector replacement is difficult for the user to perform from the viewpoint of ensuring the operational reliability of the UPS.
この発明は、 上述の如き問題点を解消するためになされたもので、 バッテリパ ックの充電中あるいは停電時の くッテリパックによるバックアツプ電源供給中に テリパックが外されようとすることに対する安全対策を施され、 コネクタ の早期破損や、 停電時の くッテリパックによるバックアツプ電源供給中に誤つて ッテ パックが外されることにより、 'ック プ電源供給が中断されること を未然に回避できるバッテリパッ交換に関して安全性に優れた無停電電源装置を 提供することを目的としている。 発明の開示  The present invention has been made in order to solve the above-mentioned problems, and has a safety measure against an attempt to remove a battery pack during charging of a battery pack or during backup power supply by a battery pack during a power failure. The battery that can prevent the interruption of the backup power supply due to the premature breakage of the connector or the accidental removal of the battery pack during the backup power supply by the battery pack during a power failure. The purpose is to provide an uninterruptible power supply with excellent safety when replacing the battery. Disclosure of the invention

The battery pack is opened and closed by a protective cover, and has a protective cover removal detecting switch for detecting that the protective cover has been removed. If the removal of the protection cover is detected by the protection cover removal detection switch during the backup power supply by the battery pack at the time of the power failure, the internal switching circuit of the power control unit is forcibly substantially opened. Or provide an uninterruptible power supply that outputs an alarm. Kill.
従って、 バッテリパックの充電中あるいは停電時のバッテリパックによるバッ クアップ電源供給中において、 保護カバ一が取り外されると、 保護カバー取外し 検出スィッチにより、 そのことが検出され、 電源制御部の内部スイッチング回路 を強制的に実質的な開成状態にする力、、 あるいは警報出力を行う。 Therefore, when the battery pack is being charged or the power is When the protective cover is removed while the backup power is being supplied, this is detected by the protective cover removal detection switch, and the force that forces the internal switching circuit of the power supply control unit to a substantial open state, or an alarm Perform output.
電源制御部の内部スィツチング回路が実質的な開成状態になると、 バッテリパ ックと電源制御部との間で充放電電流が実質的に流れなくなるから、 バッテリパ ックの取り外しが行われても、 コネクタ部分にアークが発生することがなく、 コ ネク夕の早期破損が生じることがなし、。  When the internal switching circuit of the power supply control unit is substantially opened, the charging / discharging current does not substantially flow between the battery pack and the power supply control unit. There is no arcing in the part and no early failure of the connector.
ここで云う、 実質的とは、 内部スイッチング回路のスイッチング周波数を零、 あるいはコネクタ部分にアークが発生することのない低電流状態にする零に近い 低い値にすることである。  The term “substantially” used herein means that the switching frequency of the internal switching circuit is set to zero or a low value close to zero that causes a low current state where no arc occurs in the connector portion.
また、 警報出力により、 現時点、 すなわち、 バッテリパックの充電中あるいは 停電時のバッテリパックによるバックアップ電源供給中におけるバッテリパック の取り外しを取り止めることを、 ユーザに促すことができる。  Further, the alarm output can prompt the user to stop removing the battery pack at the present time, that is, while the battery pack is being charged or the backup power is being supplied by the battery pack during a power failure.
また、 この発明は、 バッテリパックがコネクタによって電源制御部に交換可能 に導電接続された無停電電源装置において、 前記バッテリパックと前記電源制御 部とがバッテリパック出し入れ用開口部を有する本体ボックス内に収容され、 前 記バッテリパック出し入れ用開口部が保護カバ一によって開閉可能になっており 、 前記保護カバーが外れたことを検出する保護カバー取外し検出スィッチと、 前 記電源制御部の内部スィッチング回路とバッテリパック接続用の前記コネクタと の間に設けられた充放電電流遮断スィツチとを有し、 前記バッテリパックの充電 中あるいは停電時の前記バッテリパックによるバックアツプ電源供給中におし、て 、 前記保護カバー取外し検出スィツチにより前記保護カバーの取り外しが検出さ れれば、 前記充放電電流遮断スィッチを開成するか、 あるいは警報出力を行う無 停電電源装置を提供することができる。  The present invention also provides an uninterruptible power supply in which a battery pack is exchangeably conductively connected to a power control unit by a connector, wherein the battery pack and the power control unit are provided in a main body box having a battery pack access opening.
