Description

A Surge Protection Device with EMP Protection and a Surge Protection Device with EMP PCI moudule

The present invention relates to a surge protection device for protecting EMP and a semiconductor module for EMP PCI protection. More particularly, the present invention relates to a Surge and EMP shock (PCI, pulse current injection) battery for an ESS battery And a semiconductor device for EMP PCI protection, which are combined with a surge protection device that serves as an EMP protection for preventing induction in solar power generation, various kinds of automatic control DC power sources, and the like.

Generally, AC power sources are divided into P and N poles, and DC power sources have a + pole and a - pole. It is common to ground a pole (B-), but a communication DC power source, an underground line, In case of DC power supply for prevention of corrosion, + pole (B +) may be grounded.

As a countermeasure against the surge of the conventional DC power source, the varistor 10, which is a DC power source SPD, is provided between the power line (B +) and the ground G as shown in FIGS.

However, it is difficult to use a discharge element having a large capacity, a low cost, and a small variation in the discharge start voltage as compared with the discharge current, in addition to the above structure in which the varistor, which is the direct current power source SPD, is connected between the power line and ground.

As shown in the International Standard IEC61643-331 of FIG. 3, the varistor applied to the above-described conventional technique has a problem that the variation of the limit voltage characteristic varies greatly with the current. Therefore, there is an advanced battery charging control system There are insufficient problems to protect surge damage in one ESS battery system, PV system, and various control systems.

As shown in FIG. 4, due to the above-mentioned problems, the international organization IEEE may or may not protect Surge from May or may not through Survey 1100-2005 "He said.

Hereinafter, the problem of the SPD using the conventional technique will be described more closely.

When designing a varistor for a DC power source such as a general ESS battery system and a photovoltaic power generation, a limit value of a varistor is considerably higher considering a margin for a DC voltage variation rate at a normal time, It is common sense to apply 1.2 to 1.4 times.

For example, in the case of a photovoltaic power generation system for 800V DC, the varistor may vary up to 25%, that is, up to 1000V, which is 1300V considering 1.3 times margin. Thus, the varistor has a 1350V limit voltage (for example, ) Is preferably used.

However, according to IEC61643-31 varistor operating characteristic graph, when the rated current is 3000A, the general varistor exhibits the limiting voltage characteristic that is about twice the limit voltage at this time. At the large current exceeding the limit voltage, the limiting voltage deteriorates to 40,000A , A limit voltage of 7,000V may appear, which will leave the remaining voltage at 7,000V to damage the equipment.

If a SPD of the above-mentioned characteristic is applied to a photovoltaic power generation system for a DC 800V, if a surge of 3,000 A is inputted, it has a limiting voltage characteristic of about 2,700 V, and when the surge current of 40,000 A is about 7,000 V, It is a reality that the equipment is in danger of failing and it may be possible to protect or not protect Surge as shown in Fig.

In contrast, the gas discharge tube, which is a discharging device, has a short-circuited state when the surge exceeding the discharge start voltage is inputted, compared with the limiting voltage characteristic of the varistor as described above. Characteristic fluctuations (deterioration) are relatively small.

For example, a discharge tube with a discharge start voltage of 1350V will immediately discharge (normally tolerate 10%) when surge exceeding the discharge voltage is applied, shorting the line. If the power is lost to the input, the discharge stops and returns to the open state Feature.

However, when the DC power source such as photovoltaic power generation is viewed, a power supply of DC 800V / 30A is normally supplied. When the discharge element is used, once the surge flows, the DC 800V / The discharge tube can not be applied because there is a problem that the secondary current is generated due to the occurrence of the secondary current which continues the secondary discharge.

Accordingly, in the present invention, when the varistor is applied, the limiting voltage characteristic deteriorates in the overcurrent, but this phenomenon does not occur when the discharge element is used. However, due to the problem of causing secondary damage due to the flux phenomenon, And to provide a technique of using a discharge element for a direct current and an alternating current power source.

Hereinafter, a description will be made in detail of an embodiment of a surge protection device that protects EMP according to the present invention.

Generally, when lightning occurs, brain waves are generated, and the generated EEG is propagated into the air to induce surge energy by the brain current. When an EMP explosion or a nuclear explosion occurs, an electromagnetic wave EMP is generated and the generated EMP is propagated into the air Upon reaching the track, Fleming's right-hand rule induces PCI (Pulse Current Injection) energy.

In this way, PCI (Pulse Current Injection) energy caused by surge energy caused by lightning, EMP explosion, nuclear explosion, etc., is supplied to the charging control device of the ESS battery system connected to the line by the high- The photovoltaic power generation system and various electric devices may be damaged or damaged.

Accordingly, the present invention provides a surge protection device that combines EMP protection to prevent damage due to excessive energy input such as surge and PCI energy as described above.

In the present invention, since the basic shock wave absorbing method for AC, DC, and communication lines is similar, the present invention will be described as a case where the pole (B-) is grounded for convenience in order to avoid redundant explanation.

5 is a configuration diagram of a surge protection device that also serves as EMP protection according to an embodiment of the present invention.

5, the surge protective device 100 which also serves as the EMP protection of the present invention includes input side lines L1 and L2 (or ground (G), hereinafter referred to as ground G) and load side lines L1 'and L2 (Or the ground G).

The surge protector 100 includes a low frequency coupling unit 200, a surge absorption unit 300, and a PCI absorption unit 400.

The low frequency coupling unit 200 is formed between the input side L1 and the load side L1 'and the surge absorption unit 300 is formed between the input side L1 and the ground G , And the PCI absorber 400 is formed between the load side L1 'line and the ground (G) line.

Hereinafter, the low frequency coupling unit 200, the surge absorption unit 300, and the PCI absorption unit 400 will be described in detail.

The low frequency coupling unit 200 is formed between the input side L1 and the load side L1 'and is composed of a resistance component or a reactor component. The low frequency coupling unit 200 operates as a resistor or a reactor in conjunction with the PCI absorption unit 400, The DC or low frequency AC supplied from the input side is supplied to the load side according to the time constant with the absorber 400 and the surge voltage supplied from the input side or the high frequency energy caused by the PCI voltage functions to cut off the supply to the load side .

That is, the low-frequency coupling unit 200 is composed of a reactor or a resistor between a line on the input side (L1) and a line on the load side (L1 '). At this time, it is preferable that the low frequency coupling unit 200 is formed of a reactor rather than a resistor.

The low-frequency coupling unit 200 supplies DC or low-frequency alternating current supplied from the input side to the load side, and surge supplied from the input side or PCI high-frequency energy to cut off supply to the load side.

Since the low-frequency coupling unit 200 is composed of a reactor or a resistor, it blocks the passage of surges or PCI energy having a high frequency, but allows direct current or low-frequency AC to pass therethrough.

The process of passing the direct current or the low frequency commercial AC by the low frequency coupling unit 200 and interrupting the surge or PCI high frequency energy is briefly described.

Since the low frequency coupling unit 200 is formed of a resistor or a reactor, the low frequency coupling unit 200 electrically operates as 'R or L', and the PCI absorption unit 400, which will be described later, (T = RC or LC) is determined by interlocking the PCI absorption unit 400 and the operation frequency f = 1 / T is determined by the determined time constant, Frequency alternating current is passed and the high frequency energy of the PCI voltage due to the surge voltage or the EMP due to the lightning or the like having the frequency exceeding the operating frequency is blocked.

That is, the DC or commercial alternating current (60 Hz) having a frequency lower than the frequency determined by the low frequency coupling unit 200 and the PCI absorption unit 400 passes through the low frequency coupling unit 200 without any resistance, L1 '), but the surge at a frequency higher than the determined frequency value or the high frequency energy caused by the PCI is blocked.

For example, if the frequency value determined by the low frequency coupling unit 200 and the PCI absorption unit 400 is 200 Hz, a DC or commercial AC having a lower frequency will pass through the low frequency coupling unit and a surge voltage having a higher frequency or a PCI The voltage is cut off.

When the surge voltage or the high-frequency voltage of the PCI voltage is applied between the input side (L1) line and the ground (G) line, the surge absorption unit 300 is arranged between the input side L1 line and the ground And discharges the charged high frequency energy when the charging is stopped.

The surge absorption unit 300 includes the surge energy detection control module 310, the energy storage module 320, and the energy elimination module 330 to provide the above-described configuration.

When the surge voltage is applied between the input side (L1) line and the ground (G) line, the surge energy detection control module 310 operates by the applied high frequency voltage to generate high frequency energy And is provided to the storage module 320 to perform charging.

Operation characteristics of the surge energy detection control module 310 will be described in detail with reference to FIGS. 5 and 9. FIG.

In the present invention, since the surge absorption unit 300 and the PCI absorption unit 400 operate as a capacitor C and the low frequency coupling unit 200 operates as a switch that passes low frequency components and blocks high frequency components 5 can be expressed by an equivalent circuit as shown in Fig.

Therefore, when a surge is suddenly applied to a line to which a commercial AC power is applied, a short voltage short between 'bc' appears in 'bc' in FIG. 5, 'High voltage'.

When a high voltage is applied between L1 and G, the surge energy detection control module 310 operates in a state where the low frequency commercial AC voltage is normally applied. When the surge energy detection control module 310 operates, .

Therefore, when the surge energy detection control module 310 is short-circuited, the surge voltage caused by the 'high voltage' across the L1 - G or the high frequency energy due to the PCI voltage is stored in the energy storage module 320, Is consumed and exhausted according to the time constant set in the module (330).

In order to perform the above function, the surge energy detection control module 310 is configured of any one of a gas-filled discharge tube, a GCA (Gate Control Arrestor) device, and a semiconductor switching device.

More specifically, the present invention is selectively applied to a gas-filled discharge tube, which is a passive discharge element, or a GCA (Gate Control Arrestor) element, which is an active discharge element, or a semiconductor switching element.

The semiconductor switching device may be one of a silicon controlled rectifier (SCR), a triac, and a gate turn off (GTO).

In the case of the GCA (Gate Contol Arrester) element as the active discharge element, a surge frequency detection and control circuit for gate triggering is provided. A detailed description thereof will be given in Korean Patent No. 10-0817485 A discharge element having a discharge control electrode and a control circuit thereof, which will be omitted here.

A description will be given of a case where the surge energy detection control module 310 applies a gas filled discharge tube between DC power lines (+, -), that is, L1-G (L2).

When the normally used direct current voltage is 600V and the self discharge voltage of the gas filled discharge tube is set to 650V (discharge sustaining voltage is 300V), the surge voltage, which is the high frequency voltage, or the PCI voltage, When the 'high voltage' is higher than 650V, the gas-filled discharge tube discharges and is charged into the energy storage capacitor of the energy storage module 320. When the energy storage module 320 is charged, Voltage 'as well as a DC 600V component.

At this time, as the charging of the energy storage module 320 as the energy storage capacitor progresses, the voltage across the energy storage module 320 rises. At this time, the voltage of the gas filling discharge tube, which is the surge energy detection control module 310, When the discharge sustaining voltage reaches 300 V, the discharge is stopped by itself, and accordingly, the energy storage module 320 also stops charging. As a result, The energy that has been discharged while being discharged through the energy-eliminating module 330 connected to the battery 320 is exhausted.

The energy storage module 320 is characterized by an energy storing means for charging a high frequency energy caused by a surge voltage or a PCI voltage, and is preferably an energy storage capacitor.

The energy elimination module 330 is connected to the energy storage module 320 and performs a function of exhausting the high frequency energy stored in the energy storage module 320.

In order to perform the above function, the energy elimination module 330, which is a resistance component, is connected to the energy storage module 320 to exhaust the high frequency energy charged in the energy storage module.

The PCI absorber 400 is formed between a load L1 'line and a ground G line and operates as a capacitor in cooperation with the low frequency coupler 200 and is connected to the low frequency coupler 200 according to the time constant with the low frequency coupler 200 DC or low frequency commercial AC is supplied to the load side without loss and absorbs high frequency energy due to surge voltage or PCI voltage to cut off the supply to the load side.

A detailed description of the operation according to the above-mentioned operation time constant will be described later.

6, the PCI absorption unit 400 includes a waveform shaping module 420, a wave tracking module 430, and a surge module 440 including a switching module 440, A voltage switching unit 410 and a charge / discharge unit 450.

The waveform shaping module 420, the wave tracking module 430 and the switching module 440 constituting the surge voltage switching unit 410 are formed of individual chips including semiconductor devices, Of the semiconductor module.

For example, the waveform shaping module 420, the wave tracking module 430, and the switching module 440, which constitute the surge voltage switching unit 410, may include a semiconductor device for performing the respective functions, There is a disadvantage that the volume and the air volume become large. Accordingly, in a preferred embodiment of the present invention, a chip formed of the semiconductor devices is fabricated into a single semiconductor module by a lead frame method.

The output of the surge voltage switching unit 410 constitutes a charging unit 450, that is, a load.

Surge energy or PCI energy, which is a high-frequency broadband within a range of 20 KHz to 300 MHz, is removed through the surge voltage switching unit 410 and the charge / discharge unit 450 as described above.

Specifically, the waveform shaping module 420 forms a waveform of a DC voltage or a surge voltage or a PCI voltage, which is input between a load side L1 'line and a ground (G) line, The wave tracking module 430 is always provided with a constant polarity regardless of the polarity.

That is, the waveform shaping module 420 performs a function of shaping the polarity of the power or signal input to the line in one direction. Preferably, as shown in FIG. 7, the waveform shaping module 420 includes a diode bridge .

For example, the waveform shaping module 420 generates a commercial AC voltage waveform and a high frequency surge voltage when a high frequency surge voltage due to a lightning stroke or the like and a high frequency PCI voltage due to EMP are superimposed and flowed at a certain moment in a state where a commercial AC 60 Hz voltage is applied All of the PCI voltage waveforms are shaped and sent to the wave tracking module 430 at a constant polarity regardless of the positive or negative polarity.

8 shows a waveform in which the waveform of the low frequency commercial AC voltage waveform in which the waveform is shaped by the waveform shaping module 420 and the waveform of the high frequency surge voltage or the PCI voltage are superimposed.

The wave tracking module 430 detects a time band in which a surge voltage component or a PCI voltage component exists from the waveforms provided from the waveform shaping module 420 and outputs a pulse width signal having a predetermined pulse width in the detected time band. Lt; RTI ID = 0.0 &gt; 440 &lt; / RTI &gt;

Detection of the time band in which the surge voltage component or the PCI voltage component exists by the wave tracking module 430 can be detected by detecting the presence of the amplitude of the high frequency surge voltage or the high frequency PCI voltage having an amplitude much larger than the amplitude of the commercial AC voltage it means.

The pulse width of the output signal, which is the pulse width signal, refers to a pulse width corresponding to a time interval in which a surge voltage component or a PCI voltage component exists, as shown in FIG.

That is, since the wave tracking module 430 is less susceptible to fluctuation between the delayed signal and the non-delayed signal than the normal DC power source, 50 Hz / 60 Hz AC power source, or general communication signal, the pulse tracking signal that can trigger the switching module 440 A transient voltage such as a surge voltage due to a lightning stroke or a PCI voltage due to an EMP or the like causes a sufficient fluctuation between a delayed signal and a delayed signal so that a pulse width signal capable of triggering the switching module 440 is output To perform the 'latch' function.

Accordingly, the wave tracking module 430 does not provide an output signal, which is a pulse width signal, to the switching module 440 when it is a direct current power source or a 50 Hz / 60 Hz commercial AC power or communication signal. However, when the surge voltage, The switching module 440 transmits the output signal, which is a pulse width signal having a predetermined pulse width, to the switching module 440.

As shown in FIG. 7, the waveform shaping module 420 may be configured as a diode bridge, and the wave tracking module 430 may be configured to include Comp, R1, and C1. In this case, R1 and C1 are connected to the Comp (-) terminal of the module 430.

For example, the operation characteristics of the waveform shaping module 420 and the wave tracking module 430 will be described.

For example, when a commercial AC voltage of 60 Hz or 220 V is applied and the surge is superimposed at any moment and flows in the A direction, a commercial AC voltage (hereinafter referred to as &quot; AC voltage &quot;) flows through a diode bridge (+) Input terminal, which is a component of the wave tracking module 430, and is smoothed and delayed through R1 and C1, which are components of the wave tracking module 430, -) terminal.

More specifically, the rectified commercial AC voltage (231 in FIG. 8) is applied to the Comp (+) terminal which is a component of the wave tracking module 430 and the Comp (-) terminal is delayed by the time constant If the surge voltage (233 in FIG. 8) of the pulse component flows at any moment while the rectified commercial AC voltage (232 in FIG. 8) is applied, the rectified surge voltage is applied to the Comp The surge voltage component is smoothed according to the time constant according to R1 and C1, and only the commercial AC voltage component delayed by the time constant is applied to the Comp (-) terminal.

Therefore, Comp compares the output signal with the pulse width signal 234 having the pulse width corresponding to the time period in which the surge pulse exists, and outputs the pulse width signal as an output signal of the switching module 440 The gate trigger signal of SW1 causes the high frequency energy caused by the surge voltage flowing into AB to flow to R2, which is the configuration of the charging unit 450, to be destroyed.

The switching module 440 has a function of connecting the charging unit 450 with the output signal provided by the wave tracking module 430 as a trigger signal and allowing the high frequency energy of the applied surge voltage to flow to the charging unit 450 .

That is, when the pulse width signal as the trigger signal is transmitted from the wave tracking module 430, the switching module 440 is switched on (conducted) for a time corresponding to the pulse width And performs a function of connecting (turning on) the front part 450 and providing surge or PCI high frequency energy flowing into the input (A, B) line to the charging part 450 to be destroyed.

At this time, the charging unit 450 is energized by the pulse width signal which is the trigger signal of the switching module 440, and the high frequency energy due to the surge voltage applied thereto is destroyed.

The charging and discharging unit 450 is formed of any one or combination of a resistor R, an inductance L, a capacitor C and a voltage limiting device. In FIG. 7, As shown in FIG.

Meanwhile, although not shown in the drawing, the charging and discharging unit 450 may be configured by connecting an energy storage capacitor and a resistor in parallel. In this case, the surge energy is charged through the energy storage capacitor, and the energy is discharged while discharging through the resistor connected in parallel.

The PCI absorption unit 400 and the low frequency coupling unit 200 operate as a band filter for interlocking operation. In other words, the PCI absorber 400 and the low-frequency coupling unit 200 can supply DC or 60-Hz commercial AC through the low-frequency coupling unit to the load side without loss, The high-frequency voltage of the PCI voltage interrupts the supply to the load side, which will be described in detail.

Since the low frequency coupling part 200 functions as a resistance component R or L because it is constituted by a resistor or a reactor and the PCI absorption part 400 functions as a capacitor C, T = 0.7RC (or 0.7LC).

The frequency at which f = 1 / T is converted by the time constant T determined by the interlocking action of the PCI absorption unit 400 and the low frequency coupling unit 200 is determined.

The determined frequency f = 1 / T means a filtering frequency when the PCI absorption unit 400 and the low frequency coupling unit 200 operate as a band-pass filter.

The time constant coefficient is set to 0.7 in the above time equation to distinguish between the frequency of the DC or commercial alternating current of 60 Hz and the surge frequency of 20 kHz to 20 MHz or the PCI frequency of 300 MHz. Since a surge frequency of 20 MHz or a PCI frequency reaching 300 MHz is a very wide frequency band, a precise value is not required but a flat characteristic is more important. Therefore, the time constant coefficient is described as 0.7, and the present invention is not limited thereto.

The DC or commercial alternating current of 60 Hz lower than the frequency determined by the low frequency coupling part 200 and the PCI absorption part 400 passes through the low frequency coupling part 200 without any resistance or loss, And a surge voltage ranging from 20 kHz to 20 MHz or a PCI voltage component reaching 300 MHz can not pass through resistance due to the resistance component (resistance or reactance) of the low frequency coupling section 200.

On the other hand, based on the Surge Standard Specification KS C IEC61643-11 and KS C IEC61000-4-5, it is true that the energy required to generate the surge is 20uF Energy Storage Capacitor.

The surge energy detection control module 310 and the surge voltage switching unit 410 of the present invention maintain insulation at normal times when a direct current, low frequency use AC power source, etc. are applied, and the surge voltage and ESP The energy storage module 320 and the charge / discharge unit 450 have a function of storing the energy, so that there is no power consumption or signal loss at normal times.

Hereinafter, the application examples of the surge protection device that combines the EMP protection of the present invention will be described in detail.

As shown in FIG. 10, in the single mode, the low frequency coupling portion 200 is formed between the input side L1 and the input side L1 and the load side L1 'and L2' The absorber 300 and the PCI absorber 400 at both ends of the load-side line L1'-L2 '.

This has significant advantages in protecting the surge and PCI inflow through the ground wire as well as the power line or signal line.

This has the advantageous properties of protecting the Surge and PCI inflow when introduced into a power supply with solar charging and multi-phase input with multiple power inputs.

According to the above configuration, the surge and the EMP shock pulse (PCI) are induced to the AC power, the signal line, the ESS battery accompanied with the charge control, the solar power, It is possible to obtain the effect of preventing the
