Description

The present invention relates to a liquid-use load device used for an electrical load test such as a three-phase AC generator, other AC power supply, or uninterruptible power supply (USP, CVCS).

Facilities that require electric power (buildings and structures), such as computer buildings, medical institutions, commercial buildings, water departments, etc. that house factories, department stores, server computers, etc., are always stable even during power outages. Therefore, in general, in the aforementioned facilities, a private generator such as a three-phase AC generator is usually installed in the structure, and this private generator is used in the event of an emergency such as a power failure. Measures are taken so that power can be constantly supplied to the facility by operating it urgently.
As a result, even in an emergency such as a power failure, power can be stably supplied so that it does not change as usual.

However, the above-mentioned private generator is not operated at all times, and is limited to a case where it is used suddenly and limitedly at the time of an emergency power failure.
In an emergency, it is required to operate the private generator reliably and quickly to supply power. This is because when the power supply is stopped due to a power failure or the like, important work that can be operated by the power must be stopped.
Therefore, in order to check whether or not the private generator can be operated normally on a regular basis so that the private generator can be operated normally without stopping the power supply even in the event of an emergency power failure, a regular operation test, that is, a load A test is required.

Therefore, the simplest operation test of this private generator, that is, a load test, is to actually operate the private generator to generate electric power and install the electric power in a facility in a building, for example. It is conceivable that the generated power is directly supplied to devices that actually use power (power consumption devices such as indoor lighting and coolers).
However, the operation test of the private generator, that is, the load test, often takes a long time, and there are dozens of turn-on tests of the private generator and a sudden capacity increase test. It is not realistic to perform a load test by using power consumption equipment such as indoor lighting and a cooler. This is even more so during such a load test, work cannot be performed.

Therefore, in practice, a load test resistance device (load test device) having a load resistance having a capacity commensurate with the capacity of the private generator is used, and a load test of the private generator is periodically performed. The current situation is.
By the way, in recent years, load tests for so-called uninterruptible power supply devices (USP, CVCS) are increasing rapidly. An uninterruptible power supply (USP, CVCS) is a power supply that continues to supply power to connected devices (mostly computer devices) for a certain period of time, even when input power is cut off. Refers to the device.
The uninterruptible power supply mainly includes a device that receives power from a commercial power source, a device that stores the power, and a power of a certain standard from either of the former two (generally, the same as a commercial power source) ). When the connected commercial power supply is cut off, the power stored in the device is supplied to prevent instantaneous voltage drop or power outage from occurring on the device.

In recent years, there are two types of uninterruptible power supplies that are mainly used: large and centralized types used in data centers, and small and distributed types used in personal computers and medical monitors. In any case, the uninterruptible power supply is required to have high reliability.
That is, the uninterruptible power supply is not allowed to have a voltage drop or a power failure even for a moment.

Therefore, the uninterruptible power supply is installed and used in computer equipment, communication / disaster prevention / control equipment, and broadcasting equipment (station buildings / transmitting stations / large-scale relay stations) along with the installation of private generators. It has been installed and used in clean rooms, blast furnace control devices, power plants, air traffic control towers, etc., and the use of uninterruptible power supply devices is diverse and their importance is rapidly increasing.
Thus, in recent years, the need for a load test apparatus has increased rapidly not only for load tests for private generators but also for load tests for the uninterruptible power supply. It is done. In particular, load tests of uninterruptible power supply devices (USP, CVCS) as backup power sources for server computers have increased rapidly, and their importance has increased rapidly.

Here, as a resistor provided in the load test apparatus, a load resistor using a liquid, for example, a water resistor is widely used. A water resistor is a device that inserts an electrode into a water tank made of, for example, a concrete frame or a wooden frame, and adjusts the load of the private generator by adjusting the amount of the electrode inserted into the water or the distance between the poles. While stabilizing the load, it compensates for the evaporated water and adjusts the water temperature.
Conventionally, a load test apparatus 1 as shown in FIG. 5 is known as a load test apparatus using such a water resistor (for example, refer to Patent Document 1).

The load test apparatus 1 includes a water resistor 2 including three cylindrical electrodes 2a, 2a, and 2a provided for a three-phase AC generator to be tested, and a cooling water supply source that supplies cooling water. 3 and pure water means 4 including, for example, an ion exchange resin.
The water resistor 2 includes a storage tank 2b in which water is stored, and the cylindrical electrode 2a is immersed in the water M stored in the storage tank 2b. The cylindrical electrode 2a is connected to a generator (not shown) to be tested. Moreover, the outflow port 2c is provided in the upper part of the storage tank 2b, and the water M in the storage tank 2b keeps fixed height.

  Further, the cooling water supply source 3 is connected to the storage tank 2b through the supply pipe 5, and the cooling water from the cooling water supply source 3 can be supplied into the storage tank 2b. The supply pipe 5 includes a first pipe portion 5 a that directly communicates with the storage tank 2 b from the cooling water supply source 3, and a second pipe portion 5 b that communicates with the storage tank 2 b via the pure means 4.

When performing a load test with the conventional load test apparatus 1 having such a configuration, it is conceivable to perform the load test by adjusting the specific resistance of water in the storage tank 2b within a predetermined range. For example, by mixing the water directly supplied from the cooling water supply source 3 and the water having a high specific resistance via the pure means 4, the specific resistance of the water M in the storage tank 2b is adjusted within a predetermined range. The method of doing is adopted.
Japanese Patent Laid-Open No. 08-321408 (page 2-3, FIG. 1)

  By the way, in recent years, energy saving (eco-friendly) in every direction has become an important issue, and there is a demand for power saving in any electric equipment regardless of its scale and type.

However, the conventional load test apparatus 1 has a problem of remarkable power loss in the water resistor 2 and difficulty in exhaust heat treatment. That is, in the water resistor, the power generated by the private generator is simply consumed as heat, and a load test must be performed, so this power is not used at all, and the generated power is wasted. It is.
In particular, load tests for private generators are regularly performed at various large-scale power generation facilities throughout the year, and the total amount of electric power that is not effectively used at present is extremely large.

  Furthermore, in the conventional load test apparatus 1, the treatment of generated heat (exhaust heat treatment) has been a big problem. That is, in the load test apparatus 1, since the electric power is converted into heat in the water resistor 2, the temperature of the water M rises. For this reason, a large amount of cooling water is injected into the storage tank 2b to suppress an increase in the temperature of the water M. However, in order to prevent an increase in the water temperature in this way, there is a problem that a large amount of cooling water is required and it is difficult to treat the generated hot water.

  This is a problem common to, for example, a load stabilizer for stabilizing the load of a cogeneration system. That is, even in the load stabilization device of the cogeneration system, there is a problem that electric power is consumed as exhaust heat.

The present invention has been made to solve such a problem, and is used as a test in a liquid-use load device used in a load test device for an AC power source such as a private generator or a load stabilization device for a cogeneration system. It is intended to reduce the burden on the exhaust heat treatment caused by the load test while being able to effectively use the generated power.

  Below, the form for implementing this invention is demonstrated based on an Example.

  Embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the liquid-use DC load device 10 in this embodiment is connected to, for example, a three-phase AC generator 12 as a test target power source.

Note that the load test may be performed by connecting not only to the three-phase AC generator 12 but also to the uninterruptible power supply 60 or the like.
The liquid-use DC load device 10 collects the rectifier 14 that converts alternating current into direct current, the liquid-use DC resistor 20 connected to the rectifier 14, and hydrogen 15 generated by electrolysis, which will be described later. Hydrogen collection member 30, hydrogen storage unit 54 that stores hydrogen 15 collected in hydrogen collection member 30, and hydrogen-containing liquid generation that converts hydrogen 15 stored in hydrogen storage unit 54 into hydrogen-containing liquid 19 Unit 18, a hydrogen-containing liquid storage unit 21 that stores the generated hydrogen-containing liquid 19, and the hydrogen-containing liquid generation unit 18 and the hydrogen storage unit 54. And a circulation delivery part 23 for delivering the residual hydrogen 17 in the process of producing 19 from the hydrogen-mixed liquid production part 18 to the hydrogen storage part 54.

Here, the three-phase AC generator 12 is installed in a facility such as a factory or a commercial building, for example, and emergency power transmission to the factory or commercial building stops suddenly for some reason. It is intended to prevent sudden failures such as stoppage of operating power due to power outage of the facility.
Thus, the liquid-use DC load device 10 can always operate instantaneously and normally even when such a three-phase AC generator 12 has to be operated urgently for an unexpected reason. It is used as a load tester that periodically performs driving tests.
That is, to ensure that the three-phase alternating current generator 12 is always operated normally even in the case of sudden emergency operation.

  Here, the rectifier 14 includes a plurality of rectifiers 14a, 14a,... To convert alternating current from the three-phase alternating current power supply 12 into direct current. The plurality of rectifiers 14a, 14a,... Can be connected to the three-phase AC generator 12 via the switching devices 14b, 14b,.

  Further, the liquid use type DC resistor 20 includes an electrolyte aqueous solution L, for example, a storage tank 22 in which an electrolyte aqueous solution L configured by injecting, for example, about 5% of a sodium hydroxide solution is stored, and, for example, above the storage tank 22. And a plurality of electrodes 24 that are suspended from the surface.

  The storage tank 22 has an open top surface and a bottom wall 22a and a side wall 22b, and the electrolyte aqueous solution L is stored therein. Further, the storage tank 22 is provided with a liquid level detector 22c and a liquid temperature detector 22d so that the liquid level and the liquid temperature of the electrolyte aqueous solution L can be detected.

  In addition, the storage tank 22 is provided with a cooling device 26 that cools the electrolyte aqueous solution L whose temperature has been increased by being energized, and an electrolyte aqueous solution replenishing device 28 that replenishes the reduced liquid, for example, the electrolyte aqueous solution L. . Further, the electrolyte aqueous solution replenishing device 28 is provided with a deionizer 28c, which is configured to exclude foreign matter from the supplied electrolyte aqueous solution L and keep the specific resistance constant. Making the electrolyte aqueous solution L higher in purity than the pure water device 28c is considered to be effective particularly when a high voltage is applied.

The cooling device 26 includes, for example, a circulation pipe 26a having one end connected to the side wall 22b and the other end connected to the bottom wall 22a, a circulation pump 26b for circulating the electrolyte aqueous solution L, and a radiator 26c interposed in the circulation pipe 26a. And a radiator fan 26d for blowing the radiator 26c.
Further, the cooling device 26 is also connected to the liquid temperature detector 22d described above, and a detection signal is input from the liquid temperature detector 22d.

  In the liquid use type DC resistor 20, the aqueous electrolyte solution L is circulated and the radiator fan 26d is driven, and the aqueous electrolyte solution L is radiated by the radiator 26c to prevent the liquid temperature from rising. In particular, when a detection signal greater than or equal to a predetermined value is input to the cooling device 26, the rotational speed of the radiator fan 26d and the amount of circulating water are increased so that the temperature of the electrolyte aqueous solution L is maintained below a predetermined value. .

  The electrolyte aqueous solution replenishing device 28 includes a supply pipe 28a having one end connected to the electrolyte aqueous solution water supply source and the other end connected to the circulation pipe 26a, and an electromagnetic valve 28b interposed in the supply pipe 28a. Yes.

  The electromagnetic valve 28b is electrically connected to the liquid level detector 22c, and a detection signal is input from the liquid level detector 22c. Thereby, the opening and closing of the electromagnetic valve 28b is controlled, and the electrolyte aqueous solution L in the storage tank 22 can be maintained at a predetermined liquid level.

  Here, the configuration of the electrode 24 will be described. The electrode 24 is made of a conductive material such as stainless steel, and has a hollow cylindrical shape in which a part thereof is immersed in the electrolyte aqueous solution L. A plurality of the electrodes 24 are provided corresponding to the plurality of rectifiers 14a, 14a,..., And a flange 24a is provided at the upper end of each electrode 24. As a result, the electrode 24 is supported above the storage tank 22. Each flange 24a is connected to a negative (−) pole of a direct current from the corresponding rectifier 14a, so that the electrode 24 functions as a cathode.

  Further, as understood from FIG. 2, a hydrogen collecting member 30 fixed to the flange 24a by a bolt 25 is provided above the periphery of the electrode 24. The hydrogen collecting member 30 is formed of a material having electrical insulation properties and predetermined water resistance, heat resistance, and the like. Examples of such a material include an acrylic resin, an epoxy resin, a silicone resin, a melamine resin, and the like. A suitable one can be selected. Further, if the hydrogen collecting member 30 is made of FRP (Fiber Reinforced Plastics), it can be made heat resistant and chemical resistant, lightweight and strong.

  Further, the hydrogen collecting member 30 has, for example, a substantially rectangular parallelepiped shape with an open bottom surface, and its lower end 30a is immersed in the electrolyte aqueous solution L, thereby being shielded from the outside air and sealed (first space). A1 is formed.

  Furthermore, a bowl-shaped joining member 24 b having a substantially inverted U-shaped cross section is provided substantially directly above the electrode 24. The joining member 24b is in a state where the interior thereof communicates with the space A1 by the through holes 24c, 24c,... Provided in the hydrogen collecting member 30 and the flange 24a.

  In addition, the storage tank 22 is connected to the upper end of the side wall 22b with a DC positive (+) pole from the rectifier 14a. The storage tank 22 is made of an electrically conductive material such as stainless steel, and is configured so that the storage tank 22 functions as an anode.

  Further, an oxygen collecting member 32 made of an insulating material and having a substantially inverted L-shaped cross section is provided above the side wall 22b. The lower end 32a of the oxygen collecting member 32 is immersed in the electrolyte aqueous solution L, thereby forming a space (second space) A2 shielded from the atmosphere.

  The oxygen collecting member 32 is provided with an oxygen outlet 32b, so that the oxygen 55 staying in the space A2 can be stored in, for example, an oxygen storage container.

By the way, as described above, the hydrogen storage unit 30 generates the hydrogen-containing liquid generation unit 18 that converts the hydrogen 15 collected and stored into the hydrogen-containing liquid 19, for example, the organic hydride 56, and generates the hydrogen-containing liquid. A hydrogen-mixed liquid storage unit 21 that stores the hydrogen-mixed liquid 19 is connected.
A circulation sending unit 23 for sending the residual hydrogen 17 in the process of producing the hydrogen-mixed liquid 19 from the hydrogen 15 from the hydrogen-mixed liquid generating unit 18 to the hydrogen storage unit 30 is provided in the hydrogen-mixed liquid generating unit 18. As described above, the hydrogen storage unit 30 is provided.

  Next, the usage state of the liquid-use DC load device 10 having such a configuration will be described along a load test method that is normally performed.

  First, for example, a three-phase AC generator 12 as a test target power source installed in a theater, a factory, a pump station, a commercial building, or the like is connected to the rectifier 14 of the liquid-use DC load device 10.

Then, an appropriate number of switching devices 14b, 14b,... Are turned on according to the scale of the AC generator 12 and the test contents. If it does in this way, the alternating current produced | generated by the three-phase alternating current generator 12 can be sent through the rectifier 14a corresponding to the number of the switching apparatuses 14b turned on (it energizes), and it respond | corresponds to the energized rectifier 14a. A direct current converted into a direct current flows through the plurality of electrodes 24.
Thereby, the load test of the three-phase AC generator 12 can be performed by using the load due to the resistance of the liquid-use DC resistor 20 regardless of the capacity of the three-phase AC generator 12.

Here, in the liquid-use DC load device 10 of the present invention, the liquid-use DC resistor 20 includes a storage tank 22 that stores the electrolyte aqueous solution L, and an electrode 24 that is immersed in the electrolyte aqueous solution L. As already mentioned.
Then, the positive DC pole from the rectifier 14 a is connected to the storage tank 22, and the negative DC pole is connected to the electrode 24, and a liquid-use DC resistor 20 is used for the load test of the three-phase AC generator 12. The electrolyte aqueous solution L can be electrolyzed.

  In other words, the liquid-use DC load device 10 causes the storage tank 22 connected to the DC positive electrode to function as an anode, and causes the electrode 24 connected to the DC negative electrode to function as a cathode. Thus, oxygen 55 can be generated from the position near the side wall 22b of the gas 22 and gaseous hydrogen 15 can be generated from the position near the electrode 24. Hydrogen 15 and oxygen 55 can be generated and collected at a ratio of about 2: 1.

  Further, since the liquid-use DC load device 10 is provided with a plurality of electrodes 24, 24,... Connected to the negative poles of the plurality of rectifiers 14a, 14a,. The number of rectifiers 14a to be used can be appropriately selected according to the capacity of 12 and the test contents. And an appropriate electric current can be sent through the electrode 24 by this, and the electrolytic aqueous solution L can be electrolyzed more efficiently.

  Furthermore, since the liquid-use DC load device 10 of the present invention is provided with the hydrogen collecting member 30 that forms the space A1 shielded from the atmosphere above the periphery of the electrode 24, the gaseous hydrogen 15 generated from the electrode 24 is While being easily collected in the space A1 by the hydrogen collecting member 30, it is also possible to suppress heat dissipation to the atmosphere that occurs when hydrogen is generated.

Therefore, according to the liquid-use DC load device 10, the hydrogen 15 can be generated and collected using the power consumed by the liquid-use DC resistor 20 performing the load test. Therefore, it is possible to effectively use the power that has been conventionally wasted because of the load test.
In other words, in the conventional load test apparatus, the power is simply consumed as heat by the water resistor and the load test is performed, so this power is not used at all. However, in the present invention, the electric power consumed by the water resistor is not used. We converted energy into chemical energy, which could be used effectively.

  That is, in the liquid-use DC load device 10 of the present invention, most of the electric power consumed by the liquid-use DC resistor 20 is used for the electrolysis of water, so that the temperature rise of the electrolyte aqueous solution L can be kept small. it can. Therefore, the exhaust heat treatment can be performed very easily without requiring a large amount of cooling water or the like for preventing the water temperature from rising.

  Thus, the generated hydrogen 15 is collected by the hydrogen collecting member 30, and the collected hydrogen 15 is sent to the hydrogen storage unit 30 and further sent to the hydrogen-containing liquid generation unit 18.

  This is because it is extremely safe, efficient and inexpensive to store, stock and transport as a liquid mixed with hydrogen 15, that is, organic hydride 56, rather than storing, stocking and transporting as hydrogen 15.

  In the hydrogen-mixed liquid generation unit 18, the hydrogen 15 delivered from the hydrogen storage unit 30 is sequentially converted into the hydrogen-mixed liquid 19, that is, the organic hydride 56 and the like.

Here, an example of the configuration of the hydrogen-mixed liquid generator 18 will be described with reference to FIG. As shown in FIG. 3, together with hydrogen 15, for example, toluene 41, which is a kind of organic compound belonging to an aromatic hydrocarbon, is sent into the generator 40.
Here, the toluene 41 is stored in the toluene tank 42 as a liquid. For example, the toluene 41 in the toluene tank 42 is passed through the heat exchanger 43, heated to be gaseous, and the generator 40 together with the hydrogen 15. Send in.
In the generator 40, hydrogen 15 is added to the toluene 41 using, for example, platinum, nickel (not shown) as a catalyst, and for example, a gaseous organic hydride 56 is generated.

  As general reaction conditions for the reaction in the generator 40 at this time, a reaction temperature of about 170 to 210 ° C. and a reaction pressure of about 0.6 MPaG are required, whereby an organic hydride having a product concentration of 95% or more is required. 56 can be generated.

Here, for example, 3 molecules of hydrogen (3H ₂ ) 15 is added to toluene (C ₇ H ₈ ) 41 to generate methylcyclohexane (C ₇ H ₁₄ ) which is an organic hydride, and instead of toluene, For example, five molecules of hydrogen (5H ₂ ) is added to naphthalene (C ₁₀ H ₃ ), which is a kind of organic compound belonging to aromatic hydrocarbons, to produce tecarin (C ₁₀ H ₁₈ ), which is a kind of organic hydride. It's like that.

  Next, the generated high-temperature gaseous organic hydride 56 is cooled by passing it through the heat exchanger 43, and if necessary, it is further passed through the heat exchanger 44 for cooling, which is then separated into the gas-liquid separator. 45, the liquid in which the hydrogen 15 is mixed, that is, the liquid organic hydride 56 having a product concentration of 95% or more is taken out and stored in, for example, a storage tank 46, which is a kind of the hydrogen-mixed liquid storage unit 21.

Thus, the storage tank 46 can be separated from the hydrogen-mixed liquid storage unit 21 and can be separated and transported only by the storage tank 46. It can be stocked in another place, or can be used in another place by converting the hydrogen-containing liquid stored in the storage tank 46, that is, the liquid organic hydride 56 to hydrogen 15. .
Next, a simple conversion apparatus and conversion method for converting the organic hydride 56 to the hydrogen 15 and operating the hydrogen 15 will be described with reference to FIG.

Here, a hydrogen generator 47 is prepared and connected together with the storage tank 46. As shown in FIG. 4, the hydrogen generator 47 includes a reactor 48, a heat exchanger 49, a toluene tank 50, and a gas-liquid separator 51.
The organic hydride 56 taken out from the storage tank 46 is taken out from the toluene tank 50 in which, for example, the toluene 41 is stored and burned, and the reactor 48 is heated. Then, the organic hydride 56 is heated in the reactor 48 and separated into hydrogen 15 and toluene 41. It is sent to the gas-liquid separator 51 and the hydrogen 15 is taken out.

Further, if the toluene 41 separated by the gas-liquid separator 51 is returned to the toluene tank 50 and can be circulated, resources can be used without waste.
Here, in the combustion action in the reactor 48, the combustion air 51 heated by the heat exchanger 49 is used. The heat exchanger 49 can also be configured to heat the combustion air 51 using the high-temperature exhaust gas 53 generated when the toluene 41 is combusted to heat the reactor 48.

  By the way, since the storage tank 22 connected to the direct current positive electrode from the rectifier 14a functions as an anode, oxygen 55 is generated from the storage tank 22. In particular, in this embodiment, since the positive electrode is connected to the side wall 22b, most of the oxygen 55 generated by electrolysis is generated from the side wall 22b.

  Here, in the liquid-use load device 10 of the present embodiment, the oxygen collecting member 32 that forms the space A2 shielded from the atmosphere is provided above the inner side of the side wall 22b, and thus oxygen generated from the side wall 22b. 55 can be easily collected. Then, the oxygen 55 staying in the space A2 is stored in the oxygen storage container via the oxygen outlet 32b.

Thus, according to the liquid-use load device 10, the oxygen 55 generated by the electrolysis of the electrolyte aqueous solution L can be easily collected, and the oxygen 55 can be effectively used.
