Description

  The present invention relates to a greenhouse gas measuring apparatus that includes a separation-type magnetic field detection sensor that can be installed uninterruptibly and that automatically calculates greenhouse gas emissions. More specifically, in order to measure greenhouse gas emissions in any installed power consuming equipment, the power supply line of the operating equipment is not cut off, and a measuring device is installed on the power supply line without interruption. The installation of the greenhouse gas measurement system is configured to prevent damage caused by operation interruption of the equipment in operation, and to automatically calculate greenhouse gas emissions after measuring the power consumption of the equipment being measured. Relates to the device.

  In recent years, governments, local governments, companies, households, etc. have made various efforts to reduce greenhouse gas emissions that cause global warming and abnormal weather, which are becoming more serious every day. Such energy saving and reduction of greenhouse gas emissions have become a global environmental movement, and each country has introduced various environmental technologies in order to reduce greenhouse gas emissions.

There are _six greenhouse gases managed in order to prevent global warming: CO ₂ , CH ₄ , N ₂ O, HFCs, PFCs, and SF ₆ in total.

  As a method for calculating the amount of greenhouse gas emissions, there is a method of calculating by multiplying the amount of energy used by the emission factor for each greenhouse gas.

  The basic calculation formula (1) for greenhouse gas emissions by this method is as follows.

Greenhouse gas emissions = Energy source usage x Emission factor x Correction factor (1)
In the above equation (1), the “emission factor” is formulated for each type of greenhouse gas and energy source.

  On the other hand, there are various types of energy sources such as electric power, tap water, gas, hot water, steam, oils, etc. Even if the energy source is the same, if the consumption target is different, each greenhouse gas emission amount There is a difference. Here, “the energy consumption target is different” means that the emission factor varies depending on the difference in the industry classification (see Table 1 below) of the energy consumption entity and the difference in the fuel consumption equipment (for example, for each vehicle). This is the same concept as having different fuel consumption). In addition, the correction coefficient defines numerically the degree of greenhouse gas emission generated from the difference in efficiency due to aging of the same fuel consuming apparatus.

The following Table 1 shows the emission factor for each energy source and consumption object regarding CH ₄ which is one of the greenhouse gases. As shown in Table 1, it can be seen that the emission factors differ for each industry and energy source.

このように、温室効果ガス別排出係数は、計測ポイントの１箇所ごとに、温室効果ガスの種類、エネルギー源の種類、エネルギー使用量、産業区分、設備の種類、設備別特性値のような、排出係数算出用資料を準備しないと算出ができない。

In this way, the emission factor for each greenhouse gas is determined for each measurement point, such as the type of greenhouse gas, the type of energy source, the amount of energy used, the industrial category, the type of equipment, Calculation is not possible unless materials for calculating emission factors are prepared.

  As part of efforts to reduce greenhouse gases as described above, recently built buildings, factories, apartment buildings such as condominiums, etc. are equipped with facilities that have low power consumption to generate greenhouse gases. Reduce and monitor it.

  However, in spite of such efforts, since many of the power consumption devices that are measurement targets are already installed, it is actually necessary to know which equipment consumes how much power. I can't. In reality, if the unit is the whole factory, the power consumption of the whole factory can be measured, or only the total power consumption of devices connected to the existing individual power meter can be grasped. Therefore, it is impossible to grasp the power consumption of each device, and for this reason, monitoring for reducing greenhouse gases is not being performed reliably.

  In order to reduce greenhouse gas emissions, continuous monitoring is required, but most of the measurement target facilities that generate greenhouse gas are installed in factories and buildings in operation. In order to install a power consumption measuring device in such a facility, it is necessary to connect the measuring device after disconnecting the power supply line. Therefore, the factory operation is interrupted due to a power failure, the time and cost for restoration are large, and the power consumption measuring device cannot be easily installed.

  In an environment such as a home or office, a major problem does not occur even if power supply to the measurement object is interrupted for a while, but a large problem occurs in an industrial field or factory. In particular, in the case of equipment that needs to supply power for 24 hours, for example, equipment that supplies power to a product production line, a controller that collects data in real time, etc., is enormous if the power supply is interrupted even for 1 second. Can cause serious losses.

  Furthermore, even if the target does not always need to be supplied with power, if the number of installation targets increases, the time required for installation increases, resulting in interference with work. In particular, in an industrial factory, if the power supply to the production line is interrupted, it is directly linked to a loss.

  A conventional wattmeter device used for measuring greenhouse gas emissions from power consuming equipment will be described as follows.

  There are mechanical watt-hour meters, electronic watt-hour meters, contactless electronic watt-hour meters, penetrating electronic watt-hour meters, and the like as watt-hour meters for measuring the power consumption of objects that use power. .

  Of these, electronic watt-hour meters are disclosed in, for example, Korean Patent Application No. 10-2002-0068234 and Korean Patent Application No. 10-2008-0022178. A contactless electronic watt-hour meter is disclosed, for example, in Korean Utility Model Application No. 20-2008-0000226, and a penetrating electronic watt-hour meter is disclosed in, for example, Korean Utility Model Application No. 20-2003. -0030581.

  However, the electronic watt-hour meter disclosed in the above-mentioned Korean Patent Applications Nos. 10-2002-0068234 and 10-2008-0022178 is used to measure the power consumption of the object using the power. A power meter must be installed on the supply line. Also, when installing, after disconnecting the upper power supply line, it is necessary to connect both ends to a power meter, so there is a structural problem that the state of temporarily interrupting the power supply occurs .

  On the other hand, the non-contact type electronic watt-hour meter does not cause a power failure because the power supply line is passed through the power meter without disconnecting the power supply line when the power wiring work and the power meter are installed at the same time. However, there is a structural problem that a state in which the power supply has to be temporarily interrupted in order to install a wattmeter is required for a target that newly needs to measure power consumption.

  In addition, the penetrating electronic watt-hour meter has a configuration in which a power supply line is passed through the watt meter and the amount of electric energy flowing through the conducting wire is sensed. Therefore, when both ends of the power supply line are connected together, it is necessary to release the connection of the power supply line in order to additionally install a power meter, and this causes a structural problem that the power supply is interrupted was there.

  On the other hand, the above Korean patent application No. 10-2008-0022178 discloses an electronic watt-hour meter that increases accuracy for the purpose of charging, and directly measures the voltage and current amounts that are the elements of the power amount calculation. Therefore, the configuration is based on direct connection of power supply lines. Therefore, although a display is provided and the measurement amount can be confirmed with the naked eye, a function for transmitting the measurement amount to the outside is not provided.

  Hereinafter, the principle of measuring the power consumption by connecting the above-described conventional power meter to the power consumption measurement target will be described with reference to FIGS. FIG. 7 is a schematic diagram showing the principle of power measurement using a conventional electronic watt-hour meter, and FIG. 8 is a diagram of power measurement using a conventional contactless or penetrating electronic watt-hour meter. It is the schematic which shows a principle.

  As shown in FIG. 7, the principle of power consumption measurement using a conventional general electronic watt-hour meter is that a power consumption measuring instrument is installed between a main power supply unit and a measurement target. Must be connected directly. Therefore, it is a structure in which the supply of power is temporarily suspended, and cannot be applied to a target for which power consumption needs to be newly measured.

  On the other hand, as shown in FIG. 8, the principle of power consumption measurement using a contactless or penetrating electronic watt-hour meter is not required to connect the power supply line directly to the power consumption meter. It is a structure that must pass the supply line. Therefore, it is necessary to temporarily separate the power supply line in the power supply unit or the measurement target, and the power supply is temporarily suspended. In addition, it cannot be applied to a target for which power consumption needs to be newly measured. Furthermore, depending on the structure of the measuring instrument, the wiring may be bent inside the apparatus.

  As described above, the conventional watt-hour meter cannot be applied to a target for which a new need to measure power consumption has occurred, and has a function of calculating greenhouse gas emissions from the consumed power. It was not measured, only the power consumption was measured. Even if the power supply line is cut or passed and the watt hour meter is installed in each consumer device, in order to convert the information generated by the watt hour meter into greenhouse gas emissions, Complicated calculations and management are required, and it is difficult to smoothly conduct monitoring activities to reduce greenhouse gases.

  In fact, more detailed steps than existing measurement points are required to establish the reduced greenhouse gas emissions. In other words, activities that measure greenhouse gas emissions need to measure reductions before and after the introduction of environmental technology.

  In order to measure greenhouse gases, there is an important condition that only measured data is recognized only for improvement targets.

  However, many of the conventional measuring instruments for billing measure the total amount of power used by various items and facilities at the lower level. When A, B, C type equipment is used as a terminal for one power meter, even if the efficiency of A, B type equipment is improved by introducing new environmental technology, C is not improved. Measured up to mold facilities. Therefore, no matter how good the accuracy is, it is not accepted as measurement data on greenhouse gases.

  In order to be accepted as measurement data related to greenhouse gases, a new measuring instrument must be installed so as to measure only the A and B types. However, due to the structure, it is impossible to install a conventional measuring device in the case of a site where a power failure should not occur even temporarily.

  Therefore, there is a need for a device that can install a power consumption measuring device without causing a power failure at an operating industrial site and calculate the amount of greenhouse gas emissions.

  The present invention has been devised to solve such problems of the prior art, so that when installed in an operating power consumption device, the power consumption can be measured without interrupting the power supply. It has a separated type magnetic field sensor that can be installed uninterruptibly, and the measured current amount is directly calculated using the emission factor depending on the type of greenhouse gas energy source by industry and the installation location, and the amount of greenhouse gas emissions. It is an object of the present invention to provide a greenhouse gas measuring device that automatically calculates and transmits the above.

  Another object of the present invention is to provide a greenhouse gas measuring device to be used as a basis for calculating the transition of power consumption and statistical data.

  In addition, when the present invention is installed in an operating power consumption device, it operates by obtaining a power source for driving the measurement device from the power supply line through the separation type magnetic field sensing sensor without providing a separate power supply source. Another object is to provide a greenhouse gas measuring apparatus.

  A greenhouse gas measuring apparatus according to the present invention for solving the above-mentioned problems is installed around a power supply line that supplies current to a power consumption measurement target device in operation, and an induced current caused by a magnetic field generated in the power supply line A first separation type magnetic field sensing sensor for detecting a value, an A / D converter for converting a signal input from the first separation type magnetic field sensing sensor 1 connected by a circuit, and a circuit. From the electric energy consumption measured through the A / D converter, the amount of greenhouse gas emission is calculated and stored in a memory, and the control unit that controls transmission to the outside from the control unit connected by the circuit Memory that stores input data, data on the amount of electric energy used and the amount of greenhouse gas emissions transmitted through the control unit to the outside It has a data transmission unit for sending, and a pulse output unit for outputting an electric signal each time reaching the reference amount of electrical energy by utilizing the wired communication with the control unit.

According to another aspect of the present invention, there is provided a greenhouse gas measuring apparatus, comprising: a second separated magnetic field sensing sensor that supplies a circuit driving current using an induced current generated by a magnetic field generated in the power supply line;
The induced current generated by the second separated magnetic field sensor connected by a circuit is supplied and switched to power for driving the circuit, and the current supply from the second separated magnetic field sensor is interrupted. A power management unit to which power is supplied from an external power source, and a standby power source unit that stores a part of the power of the power management unit connected by a circuit, the second separated magnetic field The sensor includes a sensor body having a circular structure in which a covered power supply line is inserted and partially cut, and a separation unit 2 that is separated and coupled to the cut part of the sensor body having the circular structure. An iron core is installed in a circular shape inside the sensor body, and a coil is wound around the iron core. Both ends of the coil are covered and connected to the outside, and are connected to the power management unit.

  The greenhouse gas measuring apparatus according to still another aspect of the present invention further includes a state display unit that displays data on the amount of electric energy used and the amount of greenhouse gas emissions input through the control unit.

  According to still another aspect of the present invention, there is provided a greenhouse gas measuring apparatus, wherein the memory includes cumulative power consumption data, greenhouse gas emission cumulative data, and power consumption for calculating greenhouse gas emissions. Emission coefficient data corresponding to the measurement target device, output period value for outputting data to the state display unit, the pulse output unit, and the data transmission unit, and an electric signal for each usage amount through the pulse output unit And a reference usage amount for calculating the untransmitted data to be transmitted when a communication error occurs in the data transmitted through the data transmission unit.

  In the greenhouse gas measuring apparatus according to still another aspect of the present invention, the control unit refers to the emission coefficient data stored in the memory, and determines the amount of greenhouse gas emission appropriate for the measurement location. Greenhouse gas emissions are automatically calculated depending on the type and location of installation.

  In the greenhouse gas measuring apparatus according to still another aspect of the present invention, the first separated magnetic field sensor includes a sensor body having a circular structure in which a covered power supply line is inserted and a part thereof is cut off, A separation part that separates and couples with the cut-out part of the sensor body having the circular structure, and an iron core is installed in a circular shape inside the sensor body, and a coil is wound around the iron core. Both ends are covered and connected to the outside, and connected to the A / D converter.

  According to another aspect of the greenhouse gas measuring apparatus of the present invention, a protruding fastening part is formed on each side of the cut part of the sensor body, and the separating part corresponds to the fastening part. Fastening grooves are respectively formed to fasten with the fastening portion.

  According to the present invention, in order to measure greenhouse gas emissions, not only homes and offices that require power consumption measurement, but also industrial sites and factory buildings that have facilities where power supply must not be interrupted for 24 hours. For existing facilities such as the above, a greenhouse gas emission measuring device can be installed directly on the power supply line without interrupting the power supply.

  Further, according to the present invention, it is possible to directly calculate and transmit the amount of greenhouse gas emission at a measurement location installed on the power supply line. Therefore, as in the past, after receiving only simple power consumption information from each measurement location, the process of calculating the greenhouse gas emissions of the entire measurement location by combining them is unnecessary. It is possible to build a service that reduces the load and monitors greenhouse gas emissions more easily and efficiently.

  In other words, in general, the energy measuring device calculates only the cumulative value of power consumption, but the greenhouse gas measuring device according to the present invention determines the type of energy source appropriate for the greenhouse gas emission at the corresponding measurement location. And, after calculating the greenhouse gas emission amount using the emission factor according to the installation location, send it. Therefore, even if the management points increase, the load on the monitoring system server is small, and waste of resources of the entire system can be prevented.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the description of the present invention, when it is determined that a specific description related to a known function or a known configuration hinders understanding of the gist of the present invention, a detailed description thereof will be omitted.

  FIG. 1 is a block diagram of a greenhouse gas measuring apparatus according to the present invention. As shown in FIG. 1, a greenhouse gas measuring apparatus according to the present invention is installed around a power supply line that supplies current to a power consumption measurement target device in operation, and generates a magnetic field generated by the power supply line. 1st separation type magnetic field sensing sensor 1 for detecting the induced current value by the sensor and a second separation type magnetic field sensing sensor for supplying the circuit driving current using the induced current by the magnetic field generated in the power supply line 2, an A / D converter 3 that converts a signal input from the first separated magnetic field sensor 1 connected by a circuit, and a second separated magnetic field sensor 2 that is connected by a circuit. When the generated induced current is supplied and used by switching to the circuit driving power and the current supply is interrupted from the second separation type magnetic field sensor 2, the power management unit 4 to which power is supplied from the external power source 10 And the power tube A spare power supply unit 5 that stores a part of the electric power of the unit 4 and a greenhouse gas emission amount calculated from the electric energy consumption measured through the A / D conversion unit 3 and accumulated in the memory, and at the same time, a status display unit , Control unit 6 that controls to be transmitted through the pulse output unit and the data transmission unit, and calculates the accumulated data of the power consumption input through the control unit, the greenhouse gas emission accumulation data, and the greenhouse gas emission amount A memory 7 for storing emission coefficient data, a data output cycle value, a data transmission unit 8 for transmitting data on electrical energy usage and data on greenhouse gas emissions transmitted through the control unit to the outside, A pulse output unit 9 that is connected to the control unit and outputs an electric signal every time the electric energy reaches the reference usage amount using wired communication, and through the control unit It has a state display unit 10 to expose the data on emissions of input electric energy consumption and greenhouse gas.

  Hereinafter, each component will be described in more detail.

  The first separation-type magnetic field sensor 1 is configured to be disposed outside the greenhouse gas measurement device, and is fastened outside the coating of the power supply line connected to the power consumption measurement target. In this way, by adopting a separate sensor, it is possible to connect the sensor without disconnecting the power supply line. However, it is possible to measure the amount of power and measure the amount of greenhouse gas emissions without a power outage.

  The measurement principle is as follows. When electric power is supplied, a magnetic field is generated around the coating by a current flowing through the power supply line, and an induced current flows through the separated magnetic field sensing sensor installed around the power supply line. The intensity of the current is measured from this induced current and transmitted as an analog value.

  Next, the sensing of the electric energy usage will be specifically described.

  The electric power (P) is calculated by applying a voltage (V) to the current (I) (P = IV).

  Therefore, when the power supply line is directly connected to the measuring device as in the conventional case, the current and voltage can be directly measured, and the accurate calculation of the electric energy is possible.

  However, in the structure of the conventional power meter, when a voltage or current exceeding normal is generated in the power supply line, an abnormality occurs in the measured numerical value, and a circuit corresponding to the abnormality must be further provided.

  In the present invention, the amount of power is calculated by measuring the induced current converted from the strength of the magnetic field generated when power is supplied to the power supply line without connecting the power supply line directly as in the prior art. The configuration.

  In addition, a magnetic field detection sensor having a coil having an appropriate number of windings is provided so as to detect a magnetic field generated in the power supply line, and a current value flowing through the power supply line is measured. In this case, the current value detected by the separated magnetic field sensor is calculated proportionally from the number of windings wound around the separated magnetic field sensor so that the current value actually flowing through the power supply line can be understood. Become. For example, in the case of the number of windings wound at a ratio of 10: 1, when the measured value is multiplied by 10, the value of the current that actually flows through the power supply line is calculated.

  Moreover, the voltage value required for calculation of electric energy uses for the calculation the value provided from an electric power supplier as a constant value (for example, 220V, 380V, etc.).

  The second separation type magnetic field detection sensor 2 has the same installation method as the first separation type magnetic field detection sensor 1, but has a different function. That is, when the magnetic field generated by the current supplied to the power supply line generates an induced current in the sensor, the second separation type magnetic field sensing sensor 2 transmits the induced current to the power management unit connected by the circuit. It is transmitted and used as drive power for the control unit.

  The A / D conversion unit 3 converts the intensity of the current sensed by an analog value by the first separated magnetic field sensor 1 connected by a circuit into a digital value and transmits the digital value to a control unit connected by the circuit. To do.

  The power management unit 4 is supplied with the induced current generated by the second separation type magnetic field sensor 2 connected by a circuit, and switches to the circuit driving power for use.

  Further, a part of the induced current generated by the second separation type magnetic field sensor 2 is supplied to and stored in a standby power supply unit connected by a circuit. This is because the circuit drive power cannot be supplied through the second separation type magnetic field sensor 2 when no current flows through the power supply line, and thus the generated power is supplied to the standby power supply unit connected by the circuit. Save and use when needed.

  Further, in an environment where it is difficult to use the generated induced current as circuit drive power through the power supply line, power supplied from a separate external power source is used as circuit drive power.

  The standby power supply unit 5 accumulates a part of the power supplied to the power management unit connected by the circuit. In addition, when the supply of power from the outside is interrupted, the stored power is used to drive the circuit to be used for circuit driving. Therefore, as compared with the prior art, even when the power supplied from the outside is interrupted, the apparatus can be driven normally for a certain period of time using the power stored in the standby power supply unit.

  The control unit 6 is supplied with electric power necessary for operation through a power management unit connected by a circuit, and calculates a greenhouse gas emission amount from an electric energy usage measured by an A / D conversion unit connected by the circuit. The data is accumulated in the memory connected by the circuit and simultaneously transmitted through the state display unit 10, the pulse output unit 9 and the data transmission unit 8 connected by the circuit.

  The control unit 6 outputs the power usage data and the greenhouse gas emissions measured and calculated by the A / D conversion unit 3 to the memory connected by the circuit, and stores the accumulated data. Also, when calculating greenhouse gas emissions, the greenhouse gas emissions are automatically calculated according to the appropriate energy source type and location at the relevant measurement location with reference to the emission factor data. That is, the control unit 6 calculates the greenhouse gas emission amount by multiplying the electric energy consumption amount by the emission coefficient value with reference to the memory, and transmits it to the outside.

  The control unit 6 calls the data output cycle value stored in the memory, and transmits the data output cycle value to the state display unit, the pulse output unit, and the data transmission unit connected by the circuit according to the cycle.

  In addition, when there is an error in the data transmitted through the data transmission unit connected by the circuit, the control unit 6 stores the data in the memory, and controls to load and transmit the data at the next data transmission. .

  The memory 7 stores the accumulated data of the power usage for displaying on the status display section. In addition, the memory 7 includes cumulative data of greenhouse gas emissions for showing in the status display section, emission coefficient data corresponding to the power consumption measurement target device for calculating the greenhouse gas emissions, status display section, A pulse output unit, an output cycle value for outputting data to the data transmission unit, and a reference usage amount for calculating an electrical signal for each predetermined usage amount are stored through the pulse output unit. Further, the memory 7 stores the data to be transmitted in the memory when a communication error occurs in the data transmitted through the data transmission unit, and stores the untransmitted data in the next data transmission. Yes.

  The data transmission part 8 is a structure which transmits the data regarding the amount of electrical energy consumption, and the data regarding the discharge | emission amount of greenhouse gas to the exterior using the existing data transmission methods, such as a wire and radio | wireless. As a data transmission method, use any of the existing wired / wireless communication methods such as RF, Wibro, CDMA, HSDPA, PLC, TCP / IP, PSTN, and so on according to the power consumption measurement target of the measurement point. What is necessary is just to combine.

  The status display unit 10 is a device configuration that uses a display medium recognizable with the naked eye such as an LCD or an LED to display data on the amount of electric energy used and the amount of greenhouse gas emissions.

  The external power source 11 is preliminarily configured to supply power independently when it is difficult to drive the circuit with the induced current generated through the second separation type magnetic field sensor 2. The terminal is connected to the management unit 4.

  In the present invention configured as described above, the current amount is measured through the first separated magnetic field sensor 1, but the voltage measuring unit is omitted. The reason is that the voltage supplied to the installation site varies slightly depending on the power consumption. In the present invention, the supplied reference voltage is used for calculating the power consumption.

  That is, the present invention is not intended to charge for the usage amount as in a conventional wattmeter, but is intended to be used as a basis for calculating power consumption changes and statistical data.

  In addition, the present invention is provided with various external output units (status display unit, pulse output unit, data transmission unit) as compared with the prior art, thereby improving the usability of the device and satisfying various demands of users. It can correspond to.

  FIG. 2 is a perspective view of a separated magnetic field sensor used in the present invention, and FIG. 3 is an exemplary view showing a structure in which the separated magnetic field sensor is fastened to a power supply line.

  As shown in the drawing, the first separated magnetic field sensor 1 and the second separated magnetic field sensor 2 according to the present invention have the same structure, although they are used for different purposes.

  The separation-type magnetic field sensor has a ring shape, a covered power supply line is inserted, and a part of the sensor body 101 having a cut-out portion is separated from and combined with a part of the sensor body 101 cut-out. A separation unit 102 is included. If a uniform magnetic field can be obtained, it may be a polygonal shape instead of a circular shape. However, a circular shape is desirable because the most uniform current value can be measured.

  Projecting fastening portions 103 are formed on both sides of the incision portion of the sensor body 101. In addition, a fastening groove 104 is formed in each separation portion 102 so as to correspond to the fastening portion 103. That is, a concavo-convex structure in which the fastening portion 103 and the fastening groove 104 are connected is formed. Moreover, it can isolate | separate by pulling the isolation | separation part 102 from the downward direction to the upper direction in the state which put the sensor main body 101 in the plane.

  For this reason, the fastening portion 103 has a large outer width, and the fastening groove correspondingly has a narrow width at the entrance of the groove and a wider width toward the back. Thereby, after fastening, separation can be made difficult.

  On the other hand, when separating, the separating portion 102 may be removed using the elastic force of the sensor body 101.

  An iron core 105 is installed in a circular shape inside the sensor main body 101, and a coil 106 is wound around it. The coil is wound so as to be proportional to the amount of current flowing through the primary side (power supply line). Both ends of the coil are covered and configured to be connected to the outside such as the A / D conversion unit 3 or the power management unit 5.

  The first separation-type magnetic field sensor 1 or the second separation-type magnetic field sensor 2 configured as described above has the power supply line positioned at the center of the circular sensor body, When combined, a power meter for a greenhouse gas emission measuring device can be installed in an existing facility without disconnecting the power supply line without a power failure. In this case, when a current flows through the primary side (power supply line), an induced current flows through the coil of the first separated magnetic field sensor 1 or the second separated magnetic field sensor 2, and the induced current The value can be measured or the induced current can be used as a power source.

  Further, the size of the sensor body 101 can be changed according to the thickness of the power supply line to be measured.

  Further, the first separated magnetic field sensor 1 and the second separated magnetic field sensor 2 are not separately installed on the power supply line, but are configured and integrated together as shown in FIG. It can also be installed.

  Conventionally, the current and voltage were measured at the same time while directly connected to the power supply line, but the present invention with the above configuration allows uninterruptible installation to measure greenhouse gas emissions from existing equipment. It is.

  In the structure of the first separated magnetic field sensor 1 or the second separated magnetic field sensor 2 of the present invention described above, the error rate may slightly increase compared to the direct fastening method. However, in the greenhouse gas measurement field, if the error range of the measuring device is accurate, data measured by correcting only the error is accepted, so that the purpose of measuring greenhouse gas emissions can be achieved. Is enough. In other words, if measurement is performed using the same measuring device, it is recognized that the error range of the data before / after improvement is the same. Therefore, even if there is an error in the measuring device, there is no problem in a portion where the present invention is necessary.

  On the other hand, as in the past, a wattmeter directly connected to the power supply line to measure current and voltage at the same time cannot be measured without interrupting the current supply to the equipment under measurement. It is.

  FIG. 5 is an embodiment diagram showing the measurement principle of the greenhouse gas measuring apparatus according to one embodiment of the present invention. As shown in FIG. 5, the ring-shaped first separated magnetic field sensor 1 or the second separated magnetic field sensor 2 is fastened to the outside of the power supply line in an uninterruptible manner to supply power. It is configured not to interrupt. By driving the power consumption sensing circuit using the power generated by the induced current, it can be seen that there is no change between the power consumption measuring machine and the power wiring.

  FIG. 6 is an embodiment diagram illustrating a measurement principle of a greenhouse gas measuring apparatus according to another embodiment of the present invention. FIG. 6 shows a case where the power generated by the induced current is small and the power consumption sensing circuit is insufficient for driving the power consumption sensing circuit when the uninterruptible power supply is concluded by the method shown in FIG. The structure which drives the greenhouse gas measuring apparatus by this invention using the power supply 10 is shown.

  The preferred embodiment according to the present invention has been described above.
