The normally open contact of the third relay KM3 and the coil winding of the anti-theft electromagnetic lock 65 are connected in parallel with the unlocking power socket 41 in series. Therefore password tail circuit 47 controls anti-theft electromagnetic lock 65 electrifications at last.

In order to make the emergency unlocking circuit work, the fuse jack 43, the switch with lock 44, the code head circuit 45, the code chain circuit 46, and the code tail circuit 47 are connected in parallel with the code power jack 42 after they are connected in series. Password power supply jack 42 is used for connecting external adjustable power supply, by adjusting the output voltage of adjustable power supply and the duration of voltage to verify whether it matches with the set voltage and duration, and then determine whether to open anti-theft electromagnetic lock 65.

According to the circuit diagram shown in Figure 10, it can be seen that after the password power jack 42 is connected to the external adjustable power supply, since the normally closed contacts of the first and second time relays KT1 and KT2 are in the closed state, the password chain circuit 46 and the password tail The circuit 47 is short-circuited, and the voltage is applied to the code head circuit. At this time, only when the correct voltage U1 is input, the first relay KM1 will move, and then the first time relay KT1 will be activated. After a certain time T1, the first time relay will be activated. When KT1 acts, the cipher chain circuit 46 starts up. At this time, the input voltage needs to be switched to U2, so that the circuit can work normally. After the password chain circuit 46 works normally, the voltage U3 is switched over time T2, the password tail circuit 47 works, the normally open contact of the third relay KM3 moves, and the anti-theft electromagnetic lock 65 is started. Therefore, only when the correct voltage is input and the input voltage is switched at the correct time point can the anti-theft electromagnetic lock 65 be opened. The input voltage and the duration of the voltage become the password for opening the anti-theft electromagnetic lock 65. Therefore, the circuit shown in Figure 10 is called an emergency unlocking circuit, and its function is to unlock by inputting passwords with different voltages and different durations. As shown in Figure 12, it is a voltage curve for unlocking.

Even better, in order to increase the complexity of the password, there are multiple password chain circuits 46 . A plurality of cryptochain circuits 46 are connected in series.

Since the common distribution box usually directly crimps the cable to the lower port of the circuit breaker when carrying out external leads, in the present invention, in order to prevent the circuit breaker from being stolen, the circuit breaker is enclosed between the mounting plate 94 and the anti-theft door panel 6, Therefore, a wiring device 3 is needed to realize the connection between the circuit breaker and the external cables. Connecting the circuit breaker and external cables through the wiring device 3 also indirectly prolongs the service life of the circuit breaker. As shown in FIG. 8 , the wiring device 3 includes a fixing box 31 , a shielding plate 32 , a shielding motor 33 , and a locking electromagnetic lock 34 .

For the convenience of wiring, the fixed box 31 is a box body with one side open.

The shielding plate 32 is a rectangular plate whose size is slightly smaller than the open side of the fixed box 31 . The upper edge of the shielding plate 32 is fixedly connected to the rotating shaft of the shielding motor 33 . In order to realize the automatic control, the motor 33 and the controller 96 are electrically connected.

The shielding motor 33 is used to realize the opening and closing of the shielding plate 32 , in order to prevent artificial opening by external force, a locking through hole 311 is provided at the bottom of the fixing box 31 .

In order to realize the locking of the shielding plate 32 , a locking slot is provided on the locking bolt 341 of the locking electromagnetic lock 34 , and the locking slot penetrates up and down. When the shielding plate 32 is in the vertical state, the shielding plate 32 is plugged into the slot of the locking bolt 341 of the locking electromagnetic lock 34 . In order to realize the automatic locking of the shutter 32 , the locking electromagnetic lock 34 is electrically connected with the controller 96 .

Better, in order to distinguish the different wiring devices 3 used by internal personnel and external personnel, the wiring device 3 is set as two, one is the wiring device 301 used by internal personnel for wiring by internal personnel, and the other is for external personnel used by external personnel. Wiring device 302 is used. Correspondingly, two wiring holes are provided at the lower part of the anti-theft door panel 6, corresponding to the two wiring devices 3 respectively. In order to measure the cost of electric energy used by external personnel, an electric energy meter is added between the wiring device 302 used by external personnel and the circuit breaker.

If the temperature and humidity exceed the alarm range, an alarm message will be sent to the person in charge of the distribution box management through the communication module. The refrigerating sheet is used for cooling and condensation, and the fan is used for ventilation and cooling.

Better, in order to open the anti-theft door panel 6 more quickly in an emergency, an automatic adjustment output power supply is set for the device. The automatic adjustment output power supply can automatically output a voltage curve that matches the emergency unlocking circuit for quick unlocking. As shown in Figure 11, the automatic adjustment output power supply includes an unlock voltage output jack 48, a password voltage output jack 49, a battery, a switch S1, a starting relay KM0, a voltage regulator 317, an input capacitor Cin, an output capacitor Cout, and a reference resistor R0 , the first adjusting resistor R11, the second adjusting resistor R21, the third adjusting resistor R31, the third time relay KT3, and the fourth time relay KT4. Voltage regulator 317 adopts LM317 chip. LM317 is one of the most widely used power supply integrated circuits. It not only has the simplest form of fixed three-terminal voltage regulator circuit, but also has the characteristics of adjustable output voltage. In addition, it also has the advantages of wide voltage regulation range, good voltage stabilization performance, low noise, and high ripple rejection ratio. The standard application circuit can be obtained from the chip manual, and the output of the voltage curve can be realized by improving the standard application circuit.

The input capacitor Cin is connected in parallel with the battery. The output capacitor Cout is connected in parallel with the password voltage output jack 49 . The input terminal of the voltage regulator 317 is connected to the positive terminal of the battery. The output end is connected with the positive pole of the password voltage output jack 49 . One end of the reference resistor R0 is electrically connected to the output pin of the voltage regulator 317 , and the other end is electrically connected to the adjustment pin of the voltage regulator 317 . The negative pole of the battery is electrically connected to the negative pole of the password voltage output jack 49.

The first adjustment resistor R11 is connected in series with the normally closed contact of the third time relay KT3 and the normally open contact of the starting relay KM0 and then connected in parallel between the adjustment pin of the voltage regulator 317 and the negative pole of the battery. The second adjustment resistor R21 is connected in series with the normally open contact of the third time relay KT3 and the normally closed contact of the fourth time relay KT4 and then connected in parallel between the adjustment pin of the voltage regulator 317 and the negative pole of the battery. The third adjustment resistor R31 is connected in series with the normally open contact of the fourth time relay KT4 and connected in parallel between the adjustment pin of the voltage regulator 317 and the negative pole of the battery.

The coil winding of the third time relay KT3 is connected in parallel with the battery after being connected in series with the switch S1. The coil winding of the fourth time relay KT4 is connected in parallel with the coil winding of the third time relay KT3 after being connected in series with the normally open contact of the third relay KT3. The coil winding of the starting relay KM0 and the coil winding of the third timing relay KT3 are connected in parallel. The battery is connected in parallel with the unlocking voltage output jack 48 . A normally open contact of the starting relay KM0 is provided between the battery and the unlocking voltage output jack 48 . In order to match the anti-theft electromagnetic lock 65, the voltage of the battery matches the rated voltage of the anti-theft electromagnetic lock 65.

The jack of the automatic adjustment output power and the jack of the emergency unlocking circuit of the distribution box are connected through the banana plug test line to complete the unlocking. As can be seen from the circuit diagram shown in Figure 11, after the switch S1 is closed, the start relay KM0 and the third time relay KT3 act, at this time the normally open contact of the start relay KM0 is closed, and the voltage between the password voltage output jacks 49 is U1, According to the circuit principle, it can be known that U1=1.25×(1+R11/R0). After the third time relay KT3 is electrified, it will act after time T1. At this time, the first adjustment resistor R11 will quit working, the second adjustment resistor R21 will work when it is electrified, and the fourth time relay KT4 will be electrified. At this time, the password voltage output jack 49 The voltage is U2, U2=1.25×(1+R21/R0). After the fourth time relay KT4 has passed the time T2, the second adjustment resistor R21 quits work, and the third adjustment resistor R31 works with electricity. At this time, the voltage between the password voltage output plugs is U3, U3=1.25×(1+R31/R0) . Thus, the automatic adjustment of the output power supply automatically outputs the voltage curve for unlocking. Figure 12 is the voltage curve for opening the emergency unlocking circuit. The output voltages U1, U2, U3 can be changed by adjusting the first adjusting resistor R11, the second adjusting resistor R21, and the third adjusting resistor R31, and T1, T2 can be adjusted by adjusting the third and fourth time relays KT3, KT4.

According to the structure of an anti-theft temporary distribution box of the present invention, the usage method of the temporary anti-theft distribution box will be described below.

Method 1, move and install method. Specifically include the following steps:

Step 1.1, pull the handle 8 at the rear of the box body 91, and drag the box body 91 to a designated position on the construction site.

Step 1.2, put the box body 91 flat, open the bracket 2, take the bracket 2 out of the buckle 7, turn the bracket 2 so that the bracket 2 is located at the lower part of the box body 91.

Step 1.3, open the adjustment rod 21 on the brackets 2 on both sides, and screw the butterfly bolt at the top of the adjustment rod 21 into the screw hole of the other adjustment rod 21 .

In step 1.4, the box body 91 is erected to complete the installation.

Method 2, the method of referencing the power supply by insiders. Specifically include the following steps:

Electricity safety is an important principle, so it is necessary to check the electrified condition before operation, and operate when it is determined that there is no electricity. Input the password to open the wiring device 301 used by internal personnel on the keyboard 63.

In step 2.2, the controller 96 verifies the password. If the password is correct, then open the internal staff to use the wiring device 301, specifically:

Firstly, the controller 96 controls the locking electromagnetic lock 34 to be electrified, the locking bolt 341 of the locking electromagnetic lock 34 is retracted, the locking bolt 341 of the locking electromagnetic lock 34 is separated from the shielding plate 32, and the locking of the shielding plate 32 is released.

Then, the shielding motor 33 is controlled to rotate, the shielding plate 32 is rotated to a horizontal state, and the shielding plate 32 is opened.

Step 2.3, passing the cable through the cable entry hole 95 into the wiring device 301 for internal personnel use, and crimping the cable on the terminal.

Step 2.4, turn on the power supply, specifically: switch the transfer switch 62 to close position, close the circuit breaker, and turn on the power supply. The control of circuit breakers has changed from manual control to automatic control. Due to the development and progress of communication equipment, remote control can be realized by using communication equipment. The transfer switch 62 is electrically connected with the electric operating mechanism of the circuit breaker, and realizes the control of opening and closing of the circuit breaker by controlling the electric operating mechanism. Switching the diverter switch 62 to the on position circuit breaker is therefore closed.

Step 2.5, after the power is turned on, the controller 96 locks the shielding plate 32, specifically: control the shielding motor 33 to reverse, turn the shielding plate 32 to a vertical state, control the power-off of the locking electromagnetic lock 34, and lock the lock of the electromagnetic lock 34 The bolt 341 passes through the locking through hole 31 and is plugged into the shielding plate 32 for locking.

Step 2.6, after the electricity is used up, switch the corresponding transfer switch 62 to disconnect the circuit breaker.

Step 3.1, open the box door 92, and obtain the QR code for electricity payment through the LCD screen 64.

Step 3.2, deliver the advance payment to the administrator through the mobile phone. In real life, WeChat payment and Alipay payment are already mature technologies and their applications are relatively common, so it is possible to realize delivery prepayment.

In step 3.3, the administrator sends a control command to open the wiring device 302 for external use. Due to the development of communication technology, the Internet of Things technology is becoming more and more mature. Through mobile phone applications, it can be connected to devices with communication modules and transmit data. Therefore the administrator can send instructions to the controller 96 via the network. After receiving the instruction, the controller 96 opens the wiring device 302 for external use through the control method of step 2.2 in method 2.

Step 3.4, perform wiring and power transmission operations according to steps 2.3, 2.4 and 2.5 in method 2;

Step 3.5, after the power is used up, send a power outage application to the administrator.

In step 3.6, after receiving the application, the administrator sends an instruction to obtain power information to the controller 96 through the communication network, and the controller 96 obtains the electricity measured by the electric energy meter and sends the electricity to the administrator. The administrator calculates the electricity fee after receiving the electricity measurement. After the calculation is completed, the settlement and balance refund will be carried out. Finally, the administrator controls to open the shutter 32 of the wiring device 302 used by outsiders through network communication.

In step 3.7, the external personnel release the cables after the shielding plate 32 is opened, and then the controller 96 controls the shielding plate 32 to lock the external personnel to use the wiring device 302 .

Method 4, the method of opening the anti-theft door panel 6 during equipment maintenance, specifically:

Because the anti-theft electromagnetic lock 65 is positioned at the inside of the casing 91, it is necessary to open the chamber door 92 before opening the anti-theft door panel 6.

Under normal circumstances, the method of opening is: the administrator first communicates with the controller 96, and the controller 91 obtains the unlock command and controls the anti-theft electromagnetic lock 65 to be electrified to unlock.

In an emergency, open the anti-theft electromagnetic lock 65 by the emergency unlocking circuit, specifically:

Step 4.1, insert the output terminal of the external adjustable power supply into the password power supply jack 42, and insert the stable power supply into the unlocking power supply jack 41. An external adjustable power supply is a power supply whose output voltage can be adjusted, and a stable power supply is a power supply whose output power is stable. The matching of the voltage level of the stable power supply and the rated voltage of the anti-theft electromagnetic lock 65.

Step 4.2, install a fuse in the fuse jack 43, and use a key to open the switch 44 with a lock, and connect the emergency unlocking circuit. The fuse socket 43 is embedded on the anti-theft door panel 6, and a screw-type fuse in the prior art can be installed in an embedded panel, and the fuse tube is a plug-in type.

Step 4.3, the password of the emergency unlocking circuit is to input different voltages and the duration of different voltages is different, as shown in Figure 12, the anti-theft electromagnetic lock 65 can only be opened by outputting the voltage curve shown in the figure. Therefore, unlocking is realized by adjusting the output voltage of the adjustable power supply. The specific steps are:

First, adjust the voltage output of the adjustable power supply to U1, and last for T1 seconds,

Then, switch the voltage to U2 for T2 seconds,

Finally, the switching voltage is U3, and the anti-theft electromagnetic lock 65 is opened.

Method 5, the setting method of the password in the emergency unlocking circuit, specifically:

Step 5.1, open the anti-theft door panel 6, adjust the circuit of the emergency unlocking circuit,

In step 5.2, U1 is set by adjusting the first adjustable resistor R1. It can be seen from the circuit that the first adjustable resistor R1 divides the voltage of the coil winding of the first relay KM1, and the input voltage U1 can be determined by adjusting the size of the first adjustable resistor R1. Adjust the first time relay KT1 to adjust the duration T1. The delay time of the time relay is adjustable, so the length of the duration can be adjusted by adjusting the time relay.

In step 5.2, U2 is set by adjusting the second adjustable resistor R2, and the duration T2 is adjusted by adjusting the second time relay KT2.

Step 5.2, set U3 by adjusting the third adjustable resistor R3,

Step 5.5, close the anti-theft door panel 6 .
