(Embodiment 1) FIGS. 1 and 2 show a schematic perspective view and a schematic side perspective view, respectively, of a main part of a high-voltage power receiving and distributing facility according to Embodiment 1 of the present invention. 1 and 2, reference numeral 1 denotes an equipment case of a high-voltage power receiving and distributing equipment, 2 denotes a transformer mounted on the equipment case 1, and 3 denotes a cooling fan provided in the equipment case 1 as a gas phase transfer device. Is sucked into the equipment case 1 to cool the transformer 2 as a constituent device, and to generate a flow of air as a gas phase in the equipment case 1 to exhaust the gas to the outside. Reference numeral 4 denotes a temperature sensor disposed on the transformer 2 for detecting the temperature of the transformer 2.
5 receives the signal from the connected temperature sensor 4,
This is a monitoring and control device provided in the equipment case 1 for controlling the cooling capacity by rotating the connected cooling fan 3 at a predetermined temperature and stopping the rotation at a certain temperature.
The monitoring control device 5 also monitors the operating states of the components including the transformer 2. In the figure, reference numeral 1a denotes a door of the equipment case 1.

The operation of the high-voltage power distribution equipment constructed as described above will be described. When the load of the transformer 2 increases, the temperature of the transformer 2 rises, a temperature signal is input from the temperature sensor 4 to the monitoring and control device 5, and the monitoring and control device 5 compares this temperature with the set temperature, and sets this temperature. When the temperature becomes higher than the set temperature, a signal for driving the cooling fan 3 is output from the monitoring control device 5, and the cooling fan 3 is driven. The transformer 2 is cooled by the cooling wind of the cooling fan 3, and the temperature of the transformer 2 is reduced. It can be kept below the standard value.

As described above, the monitoring and control device 5 having the function of monitoring the operation state of the high-voltage power distribution equipment including the transformer 2 and controlling the cooling capacity of the cooling fan 3 based on the signal of the temperature sensor 4 is provided. As a result, it is possible to eliminate a separate circuit only for driving the cooling fan 3 as in the related art,
Resource saving and system operation of the cooling fan 3 become possible, so that a longer life of the cooling fan 3 and energy saving can be realized.

Further, by connecting the cooling fan 3 and the temperature sensor 4 to the monitoring control device 5, the wiring can be concentrated,
The number of steps is reduced, and low cost can be realized. Also, since the temperature sensor 4 measures the operating state of the transformer 2 according to the temperature, if the load on the transformer 2 suddenly increases or decreases, the temperature of the transformer 2 has a time constant, so that the temperature rapidly increases or decreases. Therefore, chattering of the operation of the cooling fan 3 can be prevented, and stable driving of the cooling fan 3 can be realized. In addition, the standard of the performance of the transformer 2 is defined by the temperature, and measuring the temperature of the transformer 2 is a direct measurement, so that the state of the transformer 2 can be monitored with high accuracy, and the transformer 2 can be efficiently monitored. Cooling can be performed.

Although the cooling fan 3 is used as the gas phase moving device in the first embodiment, the same effect can be obtained by using a gas phase moving device such as a compressor or an ion wind generator. . The gaseous phase according to the present invention includes air, SF6 gas, nitrogen gas, argon gas and the like.

Although the temperature is kept below the standard value, useless driving of the cooling fan 3 can be prevented,
It is possible to extend the life of the cooling fan 3 and save energy.

It should be noted that the cooling capacity of the cooling fan 3 is controlled as inverter control, and the cooling air is continuously changed to perform cooling, thereby enabling efficient operation of the cooling fan 3. Longer life and energy savings can be achieved.

FIG.
The difference from the configuration of FIG. 2 is that the temperature sensor 4 is disposed in the equipment case 1, which is a position for measuring the ambient temperature inside the high-voltage power distribution equipment.

The operation of the high-voltage power receiving and distribution equipment configured as described above will be described. When the load on the transformer 2 increases, the temperature of the transformer 2 rises, and the ambient temperature inside the equipment case 1 also rises. When the temperature input from the temperature sensor 4 that has detected this temperature to the monitoring control device 5 becomes higher than the set temperature, a signal for driving the cooling fan 3 is output from the monitoring control device 5 and the cooling fan 3 is driven, and The cooling air from the cooling fan 3 generates an airflow in the equipment case 1 and is cooled, so that the temperature inside the equipment case 1 is suppressed to a specified value or less.

As described above, the monitoring and control device 5 having the function of monitoring the operation state of the high-voltage power distribution device including the transformer 2 and controlling the cooling capacity of the cooling fan 3 based on the signal of the temperature sensor 4 is provided. Since the cooling fan 3 is provided, a separate circuit for driving the cooling fan 3 is eliminated, resources can be saved, and system operation of the cooling fan 3 can be performed, so that the life of the cooling fan 3 can be extended and energy can be saved. Further, by connecting the cooling fan 3 and the temperature sensor 4 to the monitoring and control device 5, the wiring can be concentrated, the number of steps can be reduced, and the cost can be reduced.

(Embodiment 3) FIGS. 5 and 6 are a schematic perspective view and a schematic side perspective view, respectively, showing a main part of a high-voltage power receiving and distribution apparatus according to Embodiment 3 of the present invention. In FIGS. 5 and 6, parts having the same configuration and operation as those in FIGS. 1 and 2 of the first embodiment are denoted by the same reference numerals, detailed description thereof will be omitted, and different parts will be mainly described. Reference numeral 6 denotes a load sensor for measuring a load current of the transformer 2. 1 and 2 is that a load sensor 6 is used instead of the temperature sensor 4 and the load current on the secondary side of the transformer 2 is measured.

The operation of the high-voltage power receiving and distributing equipment configured as described above will be described. When the load of the transformer 2 increases, the load current of the transformer 2 increases, and the temperature of the transformer 2 increases. A load signal is input from the load sensor 6 to the monitoring control device 5 via the connection, and when the load current becomes higher than the set current, the monitoring control device 5 drives the cooling fan 3 via the connection to the cooling fan 3. Is output to drive the cooling fan 3. Then, the transformer 2 is cooled by the cooling wind of the cooling fan 3, and the temperature of the transformer 2 is suppressed to a standard value or less.

As described above, the sensor for measuring the operation state of the transformer 2 is used as the load sensor 6, and the monitoring and control device 5 for controlling the cooling capacity of the cooling fan 3 by the load of the transformer 2 is provided. When the temperature decreases, the temperature of the transformer 2 does not rise from the temperature at that time, so that there is no need to drive the cooling fan 3.
It is determined that there is no need to drive the cooling fan 3, and the cooling fan 3 is not driven. Therefore, the cooling fan 3 does not needlessly be driven, so that the life of the cooling fan 3 can be prolonged and energy can be saved.

In this embodiment, the load on the secondary side of the transformer 2 is measured by the load sensor 6 to measure the load. However, the same effect can be obtained by measuring the primary side current. .

(Embodiment 4) FIGS. 7 and 8 show a schematic perspective view and a schematic side perspective view, respectively, of a high-voltage power receiving and distributing apparatus according to Embodiment 4 of the present invention, in which main parts are omitted. In FIGS. 7 and 8, the same components as those in FIGS. 1 and 2 of the first embodiment are denoted by the same reference numerals, detailed description thereof will be omitted, and different portions will be mainly described. Reference numeral 6 denotes a load sensor for measuring a load current of the transformer 2. 1 and FIG. 2 is that a load sensor 6 is added to the configuration of FIG. 1 and FIG. 2 and not only the temperature of the transformer 2 but also the load on the primary side or the secondary side of the transformer 2. The current is also measured.

The operation of the high-voltage power distribution equipment constructed as described above will be described. When the load on the transformer 2 increases, the temperature of the transformer 2 rises, and the temperature signal from the temperature sensor 4 and the load signal from the load sensor 6 are input to the monitoring and control device 5 via the respective connections. The monitoring control device 5 is configured to process the temperature signal and the load signal. If the change in the load measured by the load sensor 6 is less than 30% compared to the load measured 5 minutes ago, the temperature from the temperature sensor 4 The cooling fan 3 is controlled by a signal. Therefore, when the input temperature becomes higher than the set temperature, a signal for driving the cooling fan 3 is output from the monitoring control device 5 to drive the cooling fan 3, and the transformer 2 is cooled by the cooling wind of the cooling fan 3. In addition, the temperature of the transformer 2 can be suppressed below the standard value. On the other hand, if the load measured by the load sensor 6 is reduced by 30% or more compared to the load measured 5 minutes ago, the temperature of the transformer 2 drops even if the cooling fan 3 is not driven. The monitoring control device 5 stops the cooling fan 3. When the load measured by the load sensor 6 is increased by 30% or more compared to the load measured 5 minutes ago, the cooling fan 3 is controlled by the temperature signal from the temperature sensor 4 and is thus input. When the temperature becomes higher than the set temperature, a signal for driving the cooling fan 3 is output from the monitoring control device 5 to drive the cooling fan 3, and the cooling air from the cooling fan 3 cools the transformer 2, and the transformer 2 The temperature of No. 2 is suppressed below the standard value. Also,
When the cooling fan 3 is controlled only by the load sensor 6, if the load suddenly increases or decreases, the cooling fan 3 may rapidly turn on and off to cause chattering, but the temperature sensor 4 and the load sensor 6 are used together. This makes chattering less likely to occur.

As described above, the sensors for measuring the operation state of the transformer 2 are the temperature sensor 4 and the load sensor 6, and the monitoring and control device 5 for controlling the cooling capacity of the cooling fan 3 based on the temperature and the load of the transformer 2. When the load suddenly increases and decreases, the monitoring and control device 5 determines whether to perform control with temperature or control with load, and controls the cooling fan 3 so that the temperature sensor When the cooling fan 3 is controlled only by the cooling fan 4 or only the load sensor 6, the optimal and efficient control is further facilitated, the life of the cooling fan 3 can be prolonged, and energy saving can be realized. The device 2 and the high-voltage power distribution equipment can be cooled.

(Embodiment 5) FIGS. 9 and 10 show a schematic perspective view and a schematic rear view, respectively, of a main part of a high-voltage power receiving and distribution apparatus according to Embodiment 5 of the present invention. 9 and 10, parts having the same configuration and operation as those in FIGS. 1 and 2 of the first embodiment are denoted by the same reference numerals, detailed description thereof will be omitted, and different parts will be mainly described. 3a, 3
b is a plurality of cooling fans.

The operation of the high-voltage power distribution equipment constructed as described above will be described. When the load on the transformer 2 increases, the temperature of the transformer 2 rises, and is input from the temperature sensor 4 provided in the transformer 2 to the monitoring and control device 5 via a connection. When the temperature becomes higher than the set temperature, the monitoring and control is performed. A signal for driving the fans 3a and 3b is output from the device 5 via the connection. Then, the plurality of cooling fans 3a, 3b are simultaneously driven, and the transformer 2 is cooled by the cooling air of the cooling fans 3a, 3b, so that the temperature of the transformer 2 is suppressed to a standard value or less.

As described above, the monitoring and control device 5 having the plurality of cooling fans 3a and 3b, simultaneously driving the plurality of cooling fans 3a and 3b, and having the control function of stopping the cooling fans 3a and 3b is provided. And 3b are simultaneously controlled, so that control command calculation becomes easy, and uniform cooling of the transformer 2 and the high-voltage power distribution equipment can be realized.

In the fifth embodiment, the cooling fans 3a and 3b are controlled to be driven at the same time. However, a mechanism for driving only the cooling fan 3a or only the cooling fan 3b depending on the air volume required for cooling may be considered. Since the driving time of the cooling fan 3a and the cooling fan 3b is different due to the difference in the driving condition, the driving time of the cooling fan 3a and the cooling fan 3b is measured by the monitoring control device 5, and the difference in the driving time is reduced. By driving the cooling fan 3a and the cooling fan 3b, the life of the cooling fan 3a and the cooling fan 3b can be equalized and prolonged, and the transformer 2 and the high-voltage power distribution equipment can be efficiently cooled. it can.
