Description

Technical Field

[0001] The utility model relates to the technical field of exhaust fans, in particular to a cooling device used in a low-voltage power distribution room. Background Art

[0002] The low-voltage distribution room includes high-low voltage transformers, main switch cabinets, distribution cabinets, circuit breakers and other auxiliary equipment. The transformer will generate a lot of heat during operation. This heat needs to be discharged out of the room in time to avoid excessive temperature in the room that damages the transformer and electrical components.

[0003] In the prior art, a number of exhaust fans are installed on the walls inside the power distribution room for exhaust and heat dissipation. The traditional control method for the exhaust fans is to keep them on 24 hours a day. In this case, as the exhaust fans are used for a longer time, the rollers and raceways in their internal bearings will wear out. When the wear reaches a certain level, the bearings will roll unsteadily and become scrapped, and then the fan blades will get stuck, which can easily burn out the exhaust fans. Frequent repairs and replacements of exhaust fans will not only increase maintenance costs, but will also be detrimental to maintaining long-term stability in the ambient temperature inside the power room.

The control signal corresponds to the current mode signal.

[0042] The output end of the driving module 300 is electrically connected to the input end of the N cooling components. The driving module 300 receives the control signal corresponding to the current mode signal and drives the corresponding cooling components to operate, so that the N cooling components can operate in the full operation mode or the alternating cycle mode. Wherein, N is a positive integer, N≥3.

[0043] The utility model responds to the user trigger through the mode switching switch 100, outputs the current mode signal, the control module 200 receives the current mode signal, determines the current operation mode of the cooling device, outputs the control signal corresponding to the current mode signal, and the driving module 300 drives the corresponding cooling component to work according to the corresponding control signal, so as to realize that N groups of cooling components can operate in full operation mode or in alternating cycle mode. By driving the corresponding cooling components to work, the service life of the N groups of cooling components can be extended as much as possible, ensuring the long-term and efficient operation of the N groups of cooling components, reducing the failure rate, reducing maintenance costs, and maintaining the long-term stability of the ambient temperature in the low-voltage power distribution room.

[0044] In some embodiments of the present invention, each cooling assembly includes: a first cooling exhaust fan and a second cooling exhaust fan. That is, in this embodiment, referring to Figure 2 , three sets of cooling components, that is, six cooling exhaust fans are used to cool the low-voltage distribution room.

[0045] It should be noted that the cooling assembly of the present invention is not limited to setting up 3 groups, and can be extended to multiple groups. Each group is individually operated and timed through a delay relay. The time period between each group can be set according to actual conditions and is not specifically limited in the present invention.

[0046] Reference Figure 1 and Figure 3 In some embodiments of the present invention, the control module 200 includes: a first control unit 210 and a second control unit.

[0047] In this embodiment, the manual mode gear SW1 is electrically connected to the input end of the first regulating unit 210 , and the input end of the driving module 300 is electrically connected to the output end of the first regulating unit 210 .

[0048] If the current mode signal is the manual mode, the first control unit 210 receives the current mode signal and outputs the control signal corresponding to the manual mode. The driving module 300 receives the control signal corresponding to the manual mode, thereby driving the N groups of cooling components to operate in full operation mode.

[0049] That is, the mode switching switch 100 is switched to the manual mode position SW1 to drive all cooling exhaust fans to operate and quickly cool down the low-voltage power distribution room.

[0050] Among them, refer to Figure 1 , the first regulating unit 210 includes: a full-operation intermediate relay KA5.

[0051] The manual mode gear SW1 is electrically connected to the driving end of the full-operation intermediate relay KA5, and the driving module 300 is electrically connected to the normally open switch of the full-operation intermediate relay KA5. Through the driving module 300, the full-operation intermediate relay KA5 is electrically connected to the N groups of cooling components, which can drive all cooling components to operate and quickly cool down the low-voltage distribution room.

[0052] That is to say, according to the actual situation or when maintenance is required, the mode switching switch 100 can be switched to the manual mode gear SW1, the driving end of the full-operation intermediate relay KA5 is energized, the normally open point set by the full-operation intermediate relay KA5 is energized, and the driving module 300 drives the N groups of cooling components to operate in the full-operation mode, that is, drives all cooling exhaust fans to operate, so as to realize the rapid manual opening of all cooling exhaust fans, so that the N groups of cooling components operate in the full-operation mode. Among them, the manual mode is not affected by any factors such as ambient temperature and time. When several cooling exhaust fans are fully operated, the low-voltage power distribution room can be quickly cooled down.

[0053] In this embodiment, the input end of the second regulating unit is electrically connected to the automatic mode position SW2 of the mode switching switch 100 , and the input end of the driving module 300 is electrically connected to the output end of the second regulating unit.

The driving module 300 receives the control signal corresponding to the automatic mode, thereby driving N groups of cooling components to operate in an alternating cycle mode.

[0055] That is to say, the mode switching switch 100 is turned to the automatic mode gear SW2, driving one group of cooling components to run for a set time period and then stop, and the next group of cooling components continues to run for a set time period and then stops, until the N groups of cooling components are driven. The cycle is repeated again to cool the low-voltage distribution room and maintain the ambient temperature of the low-voltage distribution room within an appropriate range.

[0056] Reference Figure 1 and Figure 3 In some embodiments of the present invention, the second control unit includes: N time delay relays and N drive relays. Wherein, i=2, 3, 4, ..., N.

[0057] In this embodiment, the driving ends of the N time delay relays correspond to the driving ends of the N driving relays one by one and are connected in parallel.

[0058] That is, the driving end of the first time delay relay is connected in parallel with the driving end of the first driving relay, and the driving end of the Nth time delay relay is connected in parallel with the driving end of the Nth driving relay.

[0059] In this embodiment, the driving end of the first time delay relay is electrically connected to one end of the normally closed switch of the Nth time delay relay, and the other end of the normally closed switch of the Nth time delay relay is electrically connected to the automatic mode gear SW2. The driving end of the i-th time delay relay is electrically connected to one end of the normally open switch of the i-1th time delay relay, and the other end of the normally open switch of the i-1th time delay relay is electrically connected to the automatic mode gear SW2.

[0060] That is to say, through the normally closed switch of the last time delay relay, the driving end of the first time delay relay is electrically connected to the automatic mode gear SW2. Through the normally open point set by the last time delay relay, the driving end of the current time delay relay is electrically connected to the automatic mode gear SW2.

The normally open point of the first delay relay KT1 and the normally open point of the second delay relay KT2 are both electrically connected to the automatic mode gear SW2.

[0063] In this embodiment, the normally open switch of the Nth driving relay corresponds to the Nth group of cooling components, and the normally open switch of the Nth driving relay is electrically connected to the Nth group of cooling components through the driving module 300 .

[0064] The normally open switch of the i-1th driving relay corresponds to the i-1th group of cooling components.

[0065] The normally closed switch of the i-th drive relay is electrically connected to one end of the normally open switch of the i-1th drive relay, and the other end of the normally open switch of the i-1th drive relay is electrically connected to the drive module 300, so that the normally open switch of the i-1th drive relay is electrically connected to the i-1th group of cooling components through the drive module 300.

[0066] That is, the normally open point of the current drive relay is electrically connected to the normally closed point of the next drive relay, and the normally open point of the last drive relay is electrically connected to the last group of cooling components through the drive module 300.

[0067] For example: See Figure 1 When the value of N is 3, when the mode switching switch 100 is turned to the automatic mode gear position SW2, the first delay relay KT1 and the first drive relay KA1 are energized, and the first delay relay KT1 starts timing; the normally open point of the first delay relay KT1 is closed, and the first cooling component (M1, M2) is running. After the set time period, the normally open point of the first delay relay KT1 is closed.

[0068] The second delay relay KT2 and the second drive relay KA2 are energized, and the second delay relay KT2 starts timing; the normally open point of the second drive relay KA2 is closed, the second cooling component (M3, M4) is running, the normally closed point of the second drive relay KA2 is disconnected, and the first cooling component (M1, M2) stops running. After a set time period, the normally open point of the second delay relay KT2 is closed.

[0073] The first control unit 210 and the second control unit are connected in parallel, that is, the normally open point of the full-operation intermediate relay KA5 is connected in parallel with the switches of the N driving relays.

[0074] It can be seen from the scheme of the above embodiment that the control module 200 determines the current operating mode of the cooling device according to the current mode signal, regulates the operation of N groups of cooling components, and drives the corresponding cooling components to work, so as to realize that the N groups of cooling components can operate in full operating mode or alternating cycle mode, extend the service life of the N groups of cooling components as much as possible, ensure the long-term and efficient operation of the N groups of cooling components, reduce the failure rate, reduce maintenance costs, and maintain the long-term stability of the ambient temperature in the low-voltage distribution room.

[0075] Reference Figures 1 to 3 In some embodiments of the present invention, the cooling device further includes: a temperature detection module 400 and a drive self-locking module 500.

[0076] The output end of the temperature detection module 400 is electrically connected to the input end of the drive self-locking module 500. The temperature detection module 400 detects the current ambient temperature of the low-voltage distribution room, compares the current ambient temperature with the set temperature value, and outputs an over-temperature signal when the current ambient temperature is greater than the set temperature value.

[0077] The output end of the driving self-locking module 500 is electrically connected to the input end of the first control unit 210. The driving self-locking module 500 receives the over-temperature signal and outputs the mode locking signal to the first control unit 210 to control the N groups of cooling components to operate in full operation mode to achieve rapid cooling.

[0078] The driving self-locking module 500 includes: an over-temperature delay relay KT4 and an over-temperature intermediate relay KA4.

[0079] The driving end of the over-temperature delay relay KT4 is electrically connected to one end of the normally closed switch of the over-temperature delay relay KT4 , and the other end of the normally closed switch of the over-temperature delay relay KT4 is electrically connected to the temperature detection module 400 .

[0080] The driving end of the over-temperature delay relay KT4 is connected in parallel with the driving end of the over-temperature intermediate relay KA4, and the normally open switch of the over-temperature intermediate relay KA4 is electrically connected to the first control unit 210, that is, the normally open switch of the over-temperature intermediate relay KA4 is connected in parallel with the manual gear. The normally open switch of the over-temperature intermediate relay KA4 is also connected in parallel with the temperature detection module 400.

[0081] Reference Figures 1 to 3 When the temperature detection module 400 outputs an over-temperature signal, the relay output terminal AL1 is closed, the over-temperature intermediate relay KA4 is energized, the normally open switch of the over-temperature intermediate relay KA4 is closed, the circuit is self-locked, and the first control unit 210 is forced to operate, and all cooling components are operated. At this time, even if the current ambient temperature is lower than the set temperature value, the N groups of cooling components will not stop until the set time is reached, so as to avoid frequent start and stop of the exhaust fan due to temperature fluctuations, which may affect its service life and damage.

[0082] When the set time is reached, the normally closed switch of the over-temperature delay relay KT4 is disconnected, the over-temperature intermediate relay KA4 loses power, the normally open switch of the over-temperature intermediate relay KA4 is disconnected, and the N group cooling components operate in full operation mode.

[0083] Reference Figures 1 to 3 In some embodiments of the present invention, the driving module 300 includes: N groups of driving units.

[0084] The output ends of the N groups of driving units are correspondingly connected to the input ends of the N groups of cooling components. Each group of driving units includes: a first contactor and a second contactor. In other words, each cooling exhaust fan is electrically connected to a contactor.

[0085] The other end of the normally open switch of the i-1th driving relay is electrically connected to the input end of the i-1th group of driving units;

[0086] The other end of the normally open switch of the Nth driving relay is electrically connected to the input end of the Nth group of driving units. The normally open switch of the full-operation intermediate relay KA5 is electrically connected to the input end of the N groups of driving units. In this way, the input ends of the N groups of driving units are all electrically connected to the control module 200, and the first control unit 210 and the second control unit can drive the corresponding cooling components to operate through the driving units.

[0087] Reference Figures 1 to 3 In some embodiments of the present utility model, the cooling device further includes: a thermal relay module, a start button SB1, a stop button SB2 and a start-stop display module 600.

[0088] The input end of the thermal relay module is electrically connected to the N groups of cooling components, and the output end of the thermal relay module is electrically connected to the input end of the driving module 300. In other words, each cooling exhaust fan is individually equipped with a thermal relay and a contactor. When one of the cooling exhaust fans is abnormal, causing the thermal relay to trip, the current cooling exhaust fan will stop working and the thermal relay will cut off the power supply, the corresponding contactor will be disconnected, and the other cooling exhaust fans will not be affected and can continue to operate. At this time, the damaged cooling exhaust fan can be inspected and repaired separately.

[0089] The start-stop display module 600 is electrically connected to the start button SB1, and the stop button SB2 is electrically connected to the start-stop display module 600. The start button SB1 is electrically connected to the stop button SB2, and the start button SB1 is electrically connected to the mode switching switch 100. The start-stop display module 600 displays the start state and the stop state of the cooling device.

[0090] In this embodiment, when the stop button SB2 is pressed, the N groups of cooling components will stop immediately regardless of the current mode and status to protect the safety of equipment and personnel.

[0091] The start-stop display module 600 includes: a stop indicator light HL2, a run indicator light HL1 and a display relay. When the N cooling components are stopped, the stop indicator light HL2 is lit, and when the start button SB1 is pressed, the display relay is energized and the run indicator light HL1 is lit.

[0092] The utility model responds to the user trigger through the mode switching switch 100, outputs the current mode signal, the control module 200 receives the current mode signal, determines the current operation mode of the cooling device, and outputs the control signal corresponding to the current mode signal. The driving module 300 drives the corresponding cooling components to work according to the control signal, so as to realize that N groups of cooling components can operate in full operation mode or in alternating cycle mode. By driving the corresponding cooling components to work, the service life of the N groups of cooling components can be extended as much as possible, and the long-term and efficient operation of the N groups of cooling components can be ensured, the failure rate can be reduced, the maintenance cost can be reduced, and the ambient temperature in the low-voltage distribution room can be kept stable for a long time. In addition, through the temperature detection module 400 and the drive self-locking module 500, the circuit is self-locked, and all cooling components are forced to run until the set time, so as to avoid frequent start and stop of the exhaust fan due to temperature fluctuations, which affects its service life and damage.
