パイロツトランプである。 As shown in Figure 4, in the switching circuit, when contacts MC 1 and MC 2 of the electromagnetic contactor MC on the distribution board are closed, current flows in the direction of the arrow y in the switch element (PUT) Q 3 and the anode・As the current flows between the cathodes, current flows to the gate of thyristor Q 4 , relay RY 1 operates and its contact RY 1 becomes NO.
The commercial power supply' is connected to the regular lighting circuit Vb , and the fluorescent lamp 13 is turned on. At this time, the capacitor C2 is charged, and when the charging voltage of the capacitor C2 exceeds a predetermined value, the switch element Q3 is cut off, but the thyristor Q4 is maintained in a conductive state by the capacitor C3 . Next, contact MC 1 ,
When MC 2 is opened, the charge stored in capacitor C 2 is discharged through resistor R 2 and the capacitor is
The voltage on C 2 gradually drops. At this time, thyristor Q 1 shuts off once, excitation of relay RY 1 stops, contact ry 1 switches to the NC side, and the commercial power supply is switched off.
The power supply to the regular lighting circuit V b is stopped, and the regular lighting circuit V b enters the light-off state. When contacts MC 1 and MC 2 are opened again after about 2 hours T, the potential at point b is lower than the potential at point a because the amount of discharge of capacitor C 2 is large, and switch element Q 3 becomes conductive again. Thyristor Q 4 becomes conductive, relay RY 1 operates, and contact ry 1 switches to the NO side, so that the regular lighting circuit V b returns to the lighting state. Also, the contact
If the opening time of MC 1 and MC 2 is about T 1 hour,
The amount of discharge of capacitor C 2 is small and the potential at point b is a
Since the potential is higher than that at the point, the switch element Q3 remains in the cut-off state, and therefore the thyristor Q4 also remains in the off state. Therefore, the relay RY 1 is not energized and the contact ry 1 remains switched to the NC side, and the regular lighting circuit V b is disconnected from the commercial power supply' and turns off. In this way, relay RY 1 of the switching circuit is operated by opening and closing contacts MC 1 and MC 2 by the signal from the switching signal generation circuit, and the contact
By ry 1 , only the power supply to the regular lighting circuit V b can be interrupted. Note that R 3 to R 12 are resistors, DB 1 is a bridge rectifier, D 1 and D 2 are diodes, and PL 3 is a pilot lamp.

Regular lighting circuit
It consists of a transistor inverter V c that turns on the fluorescent lamp 13 of V b in an emergency, and by switching contact ry 1 , the power supply to the charging circuit V a continues at all times and the power supply to the normal lighting circuit V b is cut off. I am now able to connect with you.

経路で蛍光ランプ13を通常点灯させる。 To explain in more detail, when the commercial power source is normal, the storage battery 9 is charged via the power transformer 5, bridge rectifier 6, and charging resistor 7, and the voltage between the power lines A5 and A6 causes a power outage.

It falls to the NC side, and power is supplied from the storage battery 9 to the transistor inverter V c through the relay contact 10 c, and the transistor inverter V c starts high-frequency oscillation, and this high-frequency oscillation output causes the relay contact 10 to
The fluorescent lamp 13 is turned on in an emergency through the terminals a and 10b.

Since the output is delayed by T 4 hours from the side switching operation, that is, after switch SW 1 switches to the NO side as shown in FIG. 10A, T 4 as shown in FIG. 10C. After a time delay, the timer TM 4 for delaying the light-off signal times up, and as a result, the short-time energization timer TM 1 generates a gate signal to the thyristor Q 1 as shown in FIG. 10G . When switching to the NC (lighting) side and the regular lighting circuit V b is in the lighting state, the switching operation of switch SW 1 is repeated several times within a short period of time as in period K 1 in Fig. 11A. When the switch is switched to the NC side and then stopped, the energization to the relay RY 7 is interrupted accordingly, but the timer TM 4 for extinguishing time delay does not time up as shown in FIG. 11B. The gate signal to thyristor Q5 remains output,
The operation of switch SW 1 is not transmitted to relay RY 3 ,
Short-time energization timer TM 1 does not operate and does not output a gate signal to thyristor Q 1 . On the other hand, the first
After time t 3 in Figure 1 A, switch SW 1 is continuously turned to NO.
As shown in Figure 11B, when T4 hours have elapsed from time t3 , the timer for delaying the lights-out time is activated.
T 4 times up and the gate signal to thyristor Q 5 disappears. From this point on, the operation of switch SW 1 is transmitted to relay RY 3 and the short-time energization timer is activated.
TM 1 is activated and outputs a gate signal to thyristor Q 1 for a time T 1 as shown in FIG. 11C.
