Furthermore, the vacuum packaging and sealing device according to the present invention is driven by a commercial power supply,

In this case, it is preferable that the protection unit is further provided in case the overcurrent or overvoltage is supplied to the device.

That is, the vacuum packaging and sealing device according to the present invention is provided with a power supply connected to a commercial power source,

The protection unit is provided between the commercial power supply and the power supply to prevent the damage or failure of the device by cutting off the power when an overcurrent or overvoltage is applied from the commercial power supply.

As shown in FIG. 11, the protection unit 200

A surge blocking unit 210 for absorbing and blocking a surge of an input commercial AC power source,

A noise removing unit 220 for removing noise of commercial AC power passing through the surge blocking unit;

A switching unit 230 provided at an output terminal and supplying or blocking commercial AC power passing through the noise removing unit to the driving power supply unit (not shown) by an on / off switching operation;

A detection unit 240 for detecting the strength of the AC power output from the noise removing unit;

A control unit 250 which receives the detection signal of the detection unit and controls an on / off switching operation of the switching unit to cut off the overvoltage;

A counter electromotive force blocking unit 270 for blocking back electromotive force introduced from the driving power supply unit through the switching unit;

And a starting power supply unit 260 for rectifying and smoothing the output AC power of the noise removing unit to supply the starting power to the switching unit.

The surge blocking unit 210 is connected in parallel to the input terminal, and comprises a varistor (MOV1) and the arrester (A1) connected in series with each other.

A fuse F1 is connected to an input side of the surge interrupter 210 to block an overcurrent when a commercial AC power is applied.

The varistor MOV1 operates as if it is open (OFF) with a high resistance value below a specific voltage, but operates as if it is shorted because the resistance value is lowered above a specific voltage. Thus, when a surge overvoltage is input to the input terminal, it is turned on so that a current can flow.

The arrester A1 absorbs and blocks a current corresponding to a surge overvoltage introduced by the varistor MOV1 turned on. More specifically, the input current is avoided to ground so that the surge overvoltage component of the commercial AC power supply is no longer transmitted to the rear side.

The noise removing unit 220 is connected in parallel with a line filter LF1, capacitors C1 and C2 connected in parallel to both sides of the line filter LF1, and an output side of the line filter LF1. The point comprises a pair of capacitors C3 and C4 with ground FG.

The line filter LF1 is composed of two coils wound in opposite directions, and cancels noise of the in-phase component from each other and serves as a low pass filter that blocks high frequency components.

Capacitors C1 and C2 connected in parallel to both sides of the line filter LF1 allow the line filter LF1 to remove noise in a wider band.

A pair of capacitors C3 and C4 connected in parallel to the output side of the line filter LF1, more specifically, the capacitor C2 provided on the output side of the line filter LF1, has an intermediate point grounded thereto. Eliminates electromagnetic noise caused by the AC characteristics of commercial AC power supplies.

That is, the pair of capacitors C3 and C4 remove conduction noise, enhance EMC (electromagnetic compatibility), lower EMI (electromagnetic interference) by about 10 dB, and resist EMS (electromagnetic immunity) by more than 10 kV. Have it.

The switching unit 230 is provided at the output terminal of the overvoltage circuit breaker, and is turned on and off by a switching operation to turn off when the commercial AC power is an overvoltage higher than a predetermined voltage so that the overvoltage is not supplied to the driving power supply unit.

In the present invention, when the commercial AC power exceeds AC 380V, the switching unit 230 is turned off to cut off.

In the present invention, although the relay is used as the switching unit 230, a transistor capable of switching operation, a thyristor, a triac, and the like may be used as the switching unit.

As the switching unit 230, the relay includes a driving coil RC and a magnet switch RS turned on and off by an electromagnetic force of the driving coil RC.

The detector 240 includes a current transformer CT1, a bridge diode BD1, a capacitor C8, and a resistor R9.

The current transformer CT1 induces a current flowing in the primary coil provided in the output line to the secondary coil according to the turns ratio, and detects the strength of the AC power output from the noise removing unit 220.

The bridge diode BD1 rectifies the power supplied to the secondary coil of the current transformer CT1. A capacitor C7 is connected between the current transformer CT1 and the bridge diode BD1 to smooth the AC power induced in the secondary coil of the current transformer CT1.

The capacitor C8 connected to the output of the bridge diode BD1 smoothes and directs the power rectified by the bridge diode BD1.

The resistor R9 connected to the output side of the capacitor C8 transfers the power DC-directed by the capacitor C8 to the controller.

The controller 250 includes a zener diode ZD3, an S1 U1, a first transistor Q1, and a second transistor Q2.

The zener diode (ZD3) is a detection signal of the detector 240, which is transmitted through the resistor (R9), that is, the AC power output from the noise removing unit 220 is converted into a DC through the detector 240 When the supplied power becomes an overvoltage of a predetermined voltage (for example, AC 380V) or more, the power is turned on and transferred to the SR U1.

The SR U1 is triggered when the zener diode ZD3 is turned on and the power is input through the gate terminal, and is transmitted to the first transistor Q1. SLC (U1) is a silicon control rectifier (SCR) and is a semiconductor device with high reliability and stable operation.

The capacitor C9 and the resistor R3 connected to the gate terminal of the SR U1 smooth and stabilize the power transmitted by the zener diode ZD3, and input the same to the SR U1. It protects the SRC (U1) and increases the accuracy of the trigger action.

When the SR U1 is triggered, the first transistor Q1 is turned on by applying the output power of the sensing unit 240 to the gate terminal.

The resistors R4, R5, and R6 connected to the gate terminal side of the first transistor Q1 protect the first transistor and increase the stability of on-off operation.

When the first transistor Q1 is turned on, the second transistor Q2 is turned on by applying the output power of the first transistor to the gate terminal.

The resistors R7 and R8 connected to the gate terminal side of the second transistor Q2 and the diode D6 connected between the drain terminal and the source terminal protect the second transistor Q2 and perform on / off operation. Increase stability

When the second transistor Q2 is turned on, the starting power of the starting power supply unit 260 is supplied to the driving coil RC of the switching unit through the second transistor Q2, and thus the switching unit 230. Magnet switch (RS) is turned off to block the over-voltage commercial AC power supply to the drive power supply 40.

The counter electromotive force blocking unit 270 blocks the reverse electromotive force from the old driving power supply unit 140 reversely through the driving coil RC of the switching unit 230.

The back EMF blocking unit 270 includes two zener diodes ZD1 and ZD2 connected in series with the diode D5 and the varistor MOV2 connected in parallel to the driving coil RC.

The starting power supply unit 260 rectifies and smoothes the output AC power of the noise removing unit 220 to supply the starting power to the switching unit 230.

The starting power supply 260 is a bridge diode (D1 ~ D4) for rectifying the output AC power of the surge blocking unit 220, and the capacitor (C5) for smoothing the rectified power from the bridge diode (D1 ~ D4) , C6, and resistors R1 and R2 for applying the starting power smoothed by the capacitors C5 and C6 to the switching unit 33.
