本発明は蓄電池と充電部とからなる電源装置において所
定時間毎に蓄電池側の断線等の異常を検知するための無
停電電源装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an uninterruptible power supply device for detecting an abnormality such as a disconnection on the battery side at predetermined time intervals in a power supply device comprising a storage battery and a charging section.
定常状態においては商用電源から必要な電力を供給し、

電池から必要な電力を負荷側に供給するよう構成した無
停電電源装置が広汎に用いられている。In steady state, the necessary power is supplied from the commercial power source,
On the other hand, uninterruptible power supplies are widely used that are configured to supply necessary power to a load from a storage battery prepared in advance when the commercial power source is cut off.
従来技術に係るこの種の無停電電源装置の構成例を第１

蓄電池５を接続している。なお、参照符号Ｖは監視用の
電圧計を示す。A configuration example of this type of uninterruptible power supply according to the prior art is shown in the first example.
As shown in the figure. That is, in the figure, a rectifier circuit 2 is connected to the secondary side of a transformer 1 connected to a commercial power source, and a charging circuit 3 is connected to the secondary side. A switch 4 made of a relay, a silice, or the like is interposed between the rectifier circuit 2 and the charging circuit 3. Note that a storage battery 5 is connected to the output side of the charging circuit 3. Note that reference symbol V indicates a voltmeter for monitoring.

ムに重大な影響を与える不都合があった。Therefore, as shown in FIG. 1, a predetermined amount of power is normally supplied to the load from the rectifier circuit 2, and the storage battery 5 is always charged and in a standby state. In such a state, when the commercial power supply is cut off, the switch 4 is turned on at that timing, and power is supplied from the storage battery 5 to the load side to avoid an uninterrupted state on the load side. However, if the wiring to the storage battery is disconnected due to some accident, such as when the terminal of the storage battery 5 has a poor connection, the connection between the output side of the charging circuit 3 and the connection terminal of the storage battery 5 may be interrupted. The output voltage of the charging circuit 3 is displayed on the monitoring voltmeter V as in the normal state. Therefore, the monitoring voltmeter■
In this case, it is not possible to detect disconnections in the wiring system of the storage battery. For this reason, the storage battery 5 may become insufficiently charged. As a result, the operation time of the storage battery 5 is shortened and the voltage is lowered, making it impossible for the storage battery 5 to back up the load, resulting in an inconvenience that seriously affects the system.
本発明はこれらの問題点を解決するためになされたもの

It is characterized by detecting the presence or absence of an abnormality on the storage battery side by detecting the terminal voltage.
次に、本発明に係る無停電電源装置について好適な実施
例を挙げ、添付の図面を参照して以下詳細に説明する。Next, preferred embodiments of the uninterruptible power supply according to the present invention will be described in detail with reference to the accompanying drawings.
なお、以下の図中において第１図と同一の参照符号は同

。Therefore, FIG. 2 shows an embodiment of the present invention, and reference numeral 6 indicates a timer. The output side of the timer 6 is connected via a resistor R3 to a control transistor Q3 that controls the charging output in a 0N10FF manner. The output side of the comparator A2 is connected to the transistor Q3 via a resistor R4 and also to a monitor circuit (not shown) including an alarm. The output side of the error amplifier A1 is connected between the transistor Q3 and the output voltage stabilizing transistor Q1, and further connected to the backflow prevention diode D1 via the transistor Q1 and resistor R2. In addition,
The reference numeral Q2 is a transistor for overcurrent prevention.
以上のような構成において、充電部は誤差増幅器＾１お
よびトランジスタＱ１、Ｑ２を含むシリーズ型定電圧回
路であり、誤差増幅器へ１は充電部の出力電圧と基準電
圧Ｖｒｅｆｌどを比較増幅し、誤差信号を出力する。こ
の誤差信号はトランジスタ０１を制御してその出力の定
電圧化を行う。In the above configuration, the charging section is a series type constant voltage circuit including an error amplifier ^1 and transistors Q1 and Q2, and the error amplifier 1 compares and amplifies the output voltage of the charging section and the reference voltage Vrefl, etc., and calculates the error. Output a signal. This error signal controls the transistor 01 to make its output constant voltage.
充電部の出力電流は電流検出抵抗Ｒ２およびトランジス
タＱ２によって制限され過電流を防止する。The output current of the charging section is limited by current detection resistor R2 and transistor Q2 to prevent overcurrent.
一方、タイマー回路６は単位時間毎にパルスを発生しト
ランジスタＱ３を０Ｎ１０ＦＦ制御する。On the other hand, the timer circuit 6 generates a pulse every unit time and controls the transistor Q3 to be 0N10FF.
従って、トランジスタＱ３のＯＦＦ時には充電部は通常
の定電圧動作を行う。一方、にトランジスタＱ３がＯＮ
するとこのトランジスタＱ３のコレクタ電位は低下して
略零電位となる。従って、トランジスタＱｌはＯＦＦ
して充電部の出力電圧は低下する。Therefore, when transistor Q3 is OFF, the charging section performs normal constant voltage operation. On the other hand, transistor Q3 is turned on
Then, the collector potential of this transistor Q3 decreases to approximately zero potential. Therefore, transistor Ql is OFF
As a result, the output voltage of the charging section decreases.
コンパレータ舷は蓄電池端子電圧と基準電圧Ｖｒｅｆ２

以上の場合にはコンパレータＡ２の出力はローレベルと

ジスタ０３はタイマー回路６の信号によって制御される
。The comparator side is the storage battery terminal voltage and the reference voltage Vref2
Compare. The terminal voltage of the storage battery is the reference voltage Vref2
In the above case, the output of comparator A2 becomes low level. Therefore, even if the output side of the comparator A2 is connected to the base of the transistor Q3 via the resistor R4, this transistor is not affected in any way, so the transistor 03 is controlled by the signal from the timer circuit 6.
そこで、以上のような構成において、先ず、外部蓄電池
を接続し、蓄電池端子電圧が基準電圧Ｖｒｅｆ２以上に
上昇するとコンパレータΔ２は反転しローレベルとなる
。このためトランジスタ０３はＯＦＦ’ して充電部は
動作状態となる。同時にモニター出力もローレベルに反

Ｎする。従って、充電部は起動することなく充電出力電
圧も出力されない。同時にモニター出力はハイレベルと
なるために、例えば、警報器等により異常がある旨を知
らせることになる。Therefore, in the above configuration, first, an external storage battery is connected, and when the storage battery terminal voltage rises above the reference voltage Vref2, the comparator Δ2 is inverted and becomes a low level. Therefore, the transistor 03 is turned OFF' and the charging section becomes operational. At the same time, the monitor output is also inverted to low level. In this way, if the external storage battery is connected normally, the charging section will operate normally, and even if the operation of the charging section is stopped by the pulse signal periodically generated from the timer circuit 6 and the charging output voltage is lowered, the charging section will not be monitored. A signal indicating an abnormality, that is, a high level signal cannot be received at one terminal. On the other hand, when the external storage battery is not connected to the storage battery terminal, the storage battery terminal voltage is zero, so the output of the comparator 82 becomes high level, and the transistor Q3 turns OFF.
Do N. Therefore, the charging section does not start up and no charging output voltage is output. At the same time, the monitor output becomes high level, so that, for example, an alarm or the like is used to notify that there is an abnormality.

並びにモニター出力の各動作モードを示す。In this way, it is possible to monitor abnormalities such as the quality of connection of the external storage battery by detecting the storage battery terminal voltage. In this case, if the cycle of the above-mentioned monitoring operation is several minutes or more, and the charging part stops operating for 1 to 2 seconds, the ratio to the charging time will be less than 1%, and the effect on the charging time can be ignored. . Incidentally, FIG. 3 shows each operation mode of the timer output, external storage battery output, battery terminal output, charging section output, and monitor output related to the above operation.

が可能であることは勿論である。In the above explanation, a series type constant voltage circuit was used as an example of the configuration of the charging part, but any other type of charging part can be used as long as the output voltage can be reduced or cut off by an external signal, such as a switching regulator. Of course, it is possible to do so.

ーできるという利点がある。As described above, according to the present invention, it is possible to constantly monitor whether or not a storage battery is connected without affecting the charging time of the storage battery. Therefore, it is possible to prevent a system failure of the uninterruptible power supply. In addition, at the end of a storage battery's life, even if the terminal voltage is normal, if a discharge current is applied, the voltage will drop sharply, so by applying an arbitrary bleeder current during the charging suspension period, the quality of the storage battery can be monitored. There is.
