2. Description of the Related Art There is known a configuration in which a plurality of storage batteries (also called a plurality of storage battery cells) are housed in a standard cabinet of a switching device in a communication system device, and the storage batteries and the switching device are installed in parallel. In a configuration in which such a storage battery is housed in a cabinet, a plurality of storage batteries are usually connected in series and used in a boosted state. That is,
The positive electrode and the negative electrode of each storage battery are sequentially connected to the adjacent storage batteries to form a storage battery module in which a fixed number of them are connected in series. In order to reduce the floor area required for the entire storage battery module, a cabinet is provided with shelves, and storage batteries are stacked and installed vertically in the cabinet.

In recent years, sealed storage batteries such as sealed lead storage batteries have been developed, and the possibility of releasing harmful gas to the surroundings has been reduced. Therefore, the storage batteries are stored in a sealed cabinet (also referred to as a case or a rack). It has become possible. In a communication system device, by installing a storage battery storage cabinet that is a cabinet for storing storage batteries adjacent to a load exchange and a transmission device, power loss and voltage drop in power wiring due to low voltage and large current can be prevented. Since it can be reduced, the effect of storing the storage battery in the cabinet is great.

3'and the back panel 12 are further separated, and the parallel breaking mechanism control pin 82 is completely disconnected from the connector provided on the back panel 12. At this time, the plug-in unit connector 80 sends a shutoff signal to the shutoff mechanism 70 to change the shutoff mechanism 70 to the open (OFF) state (ST3). In this state, the parallel power supply pin 81 is still
Is connected to the connector provided on the back panel 12, the plug-in unit connector 80
Is supplied with power via a power supply pin 81.

After that, the side plate 13 'of the plug-in unit 13 and the back panel 12 are further separated from each other, and the power supply pin 81 is also completely separated from the connector provided on the back panel 12, and the plug-in unit connector. The power supply to 80 also disappears (ST4). Above,
The disconnection of the plug-in unit 13 from the back panel 12 is completed.

As a result, before the storage battery 6 in the plug-in unit 13 is electrically disconnected from the connector of the back panel 12 to which the hot line is connected, the disconnection mechanism 70 for disconnecting the electric circuit connecting the storage battery 6 to the hot line is performed. Since it is in a non-active state, it is possible to prevent damage to the contact portion such as the connector of the back panel 12.

The detection of the complete disconnection of the parallel cutoff mechanism control pin 82 is performed, for example, by the voltage drop of the resistor connected in series with the cutoff mechanism control pin 82 or the parallel cutoff between the parallel power supply pins 81. This is performed by detecting the voltage of the shutoff mechanism control pin 82. If the parallel shutoff mechanism control pin 82 is disconnected, the impedance becomes high and noise may occur, causing a malfunction. As a method of preventing this malfunction, the parallel power supply pin 81
It is effective to connect a resistor in parallel between the terminals of the parallel breaking mechanism control pin 82 connected in between.

Next, referring to FIG. 9B, when the plug-in unit 13 is housed in the cabinet 1, that is, when the plug-in unit 13 is connected to the back panel 12, the plug-in unit connector 80 and the disconnection unit are cut off. Mechanism 7
The operation of 0 will be described.

First, the plug-in unit 13 is gradually inserted into the cabinet 1 (ST11). As a result, the side plate 13 ′ of the plug-in unit 13 and the back panel 12 gradually approach each other, and the parallel power supply pin 81
Also, the parallel shutoff mechanism control pin 82 gradually approaches the connector provided on the back panel 12.

After that, when the plug-in unit 13 is further inserted into the cabinet 1, the parallel power supply pin 81
And the connector provided on the back panel 12 are connected (ST12). At this time, the parallel shutoff mechanism control pin 82
Is shorter than the parallel power supply pin 81 and is not connected to the connector provided on the back panel 12.

After that, while further inserting the plug-in unit 13 into the cabinet 1, it is judged whether or not the parallel break mechanism control pin 82 is connected to the connector provided on the back panel 12 (ST13, ST14).

After that, the plug-in unit 13 is further inserted into the cabinet 1, and if it is determined in ST13 that the parallel break mechanism control pin 82 is connected to the connector provided on the back panel 12, the break mechanism 70 is selected. A connection signal is sent to and the breaking mechanism 70 is changed to the open (OFF) state (ST15).

As a result, when the plug-in unit 13 is connected to the back panel 12, the parallel power supply pin 81 is first connected to the connector of the back panel 12,
After that, the parallel shutoff mechanism control pin 82 is set on the back panel 12.
Since the storage battery 6 is connected to the live line when the storage battery 6 is connected to the live connector, the storage battery 6 is connected to the live line in a state where the connectors other than the connector for the parallel cutoff mechanism control pin 82 are incomplete. This makes it possible to prevent the occurrence of joules when connecting the connector.

FIG. 10 is a conceptual block diagram of a circuit provided on the back panel 12. The back panel 12 is provided with a voltage detection circuit 31, a determination circuit 32, and a bypass circuit 33.

Further, instead of the voltage detection circuit 31 detecting the voltage between the cable connectors 24, the parallel breaking mechanism control pin 82 of the plug-in connector 28 shown in FIG. 8 detects whether or not the plug-in unit 13 is connected. The determination circuit 32 determines the detection result, and the bypass circuit 3
3 may be operated.

And a connecting portion 33d for connecting 33a.

Further, the power supply 33a has a regulator that divides the power output from the secondary battery, the electric double layer capacitor, or the like.

Since the power storage device 33 'is used temporarily, if the current flowing through the storage battery module 61 is passed as it is and the voltage rise or the voltage drop of the power storage device 33' is too large, the control unit 33c. Is the power source 3
The voltage of the power storage device 33 'is kept within a predetermined range by shunting the regulator 3a or supplying a current from the power supply 33a. That is, the controller 33c controls the voltage detector 33b.
Voltage of the power storage device 33 'is monitored through the power supply device, and when the voltage rises above a predetermined allowable value, the current is shunted to the regulator of the power supply 33a, and when the voltage is below the predetermined allowable value, the power supply The output voltage of 33a is increased.
