Description

Technical Field

[0001] The invention relates to the technical field of power systems, and in particular to a cooling system for a transformer radiator. Background Art

[0002] When the oil-immersed self-cooling transformer is working, it uses the internal and external temperature difference and the convection of oil to dissipate the heat energy converted from the energy loss in the core and winding to the surrounding through the radiator to maintain normal operation. The self-cooling heat dissipation method of the oil-immersed self-cooling transformer is limited by the ambient temperature and system load, especially in the summer when the system load is large and the external temperature is continuously high. If there are no auxiliary heat dissipation measures, the heat generated cannot be effectively dissipated to the outside world, which will accelerate the aging of the transformer insulation medium, thereby shortening the transformer's operating life and seriously threatening the power supply reliability of the power grid.

[0003] At present, a water spray cooling device is used to cool the radiator on the oil-immersed self-cooling transformer. However, the existing water spray cooling device has a relatively simple structure, and the cooling is assisted by spraying through a nozzle installed on the top of the radiator. Not only is the spraying area limited, but the water flow cannot effectively cover the surface of the radiator, so the spray cooling effect is not good. In addition, the existing water spray cooling device relies on manual control of the start and stop of the nozzle, and can only maintain a normally open or normally closed state, and cannot achieve automatic adjustment of the start and stop. At the same time, since most substations adopt an unattended mode, manual start and stop have a certain time lag, which not only fails to achieve an effective cooling effect, but also wastes a lot of water resources and manpower.

[0004] Therefore, in order to solve the above problems, a new cooling method for transformer radiators is urgently needed, which can not only improve the spray cooling effect, but also realize intelligent control functions to enhance practicality and reduce the waste of resources and manpower.

[0041] Figure 3 The present invention provides a control logic diagram of an electrical control circuit for a solenoid water valve in a cooling system for a transformer radiator provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] like Figure 1 As shown in the figure, a cooling system for a transformer radiator is proposed in an embodiment of the present invention, including a spray cooling device; the spray cooling device includes a main pipeline 1, a first auxiliary pipeline 2, a water valve 3, a top nozzle 4 and a side wall nozzle 5; wherein,

[0044] The main pipeline 1 is a PVC pipe and is installed below the radiator L of the designated transformer, and one end port thereof is a water inlet, and the other end port forms a sealing structure (i.e., through a plug or other means), and a middle portion is provided with N first mounting holes (not shown) for mounting the first auxiliary pipeline 2; wherein N is a positive integer greater than 1; and each first mounting hole is a through hole;

[0045] The first auxiliary pipes 2 are PVC pipes and there are N of them; any two adjacent first auxiliary pipes 2 are spaced apart by at least one heat sink L1 preset on the radiator L; each first auxiliary pipe 2 is located between two heat sinks L1, and one end port thereof is installed in a corresponding first mounting hole of the main pipe 1 and is connected to the corresponding first mounting hole, and the other end port is located above the radiator L and is installed with a top nozzle 4, and a side wall nozzle 5 is installed in the middle part;

[0046] Each top nozzle 4 is a plastic or metal nozzle, and is provided with at least one group of first water spray holes (not shown); each group of first water spray holes is composed of a plurality of through holes arranged radially around the connected first auxiliary pipe 2;

[0047] Each side wall nozzle 5 is a plastic or metal nozzle, and is provided with at least one group of second water spray holes (not shown); each group of second water spray holes is composed of a plurality of through holes arranged in the axial direction of the connected first auxiliary pipe 2;

[0048] The water valve 3 is a mechanical water valve or an electromagnetic water valve, which is arranged on the main pipeline 1 and close to the water inlet of the main pipeline to control the water flow into the main pipeline 1.

[0049] At this time, when the water valve 3 is opened, each group of first water spray holes scatters the water flow in a horizontal disc shape, so that the water flows down from the top along the corresponding side wall of the heat sink L1 to form a water film to cover a partial area of ​​the side wall of the heat sink L1. At the same time, each second water spray hole scatters the water flow in a vertical disc shape, so that the water flow is scattered in the axial direction of the corresponding heat sink L1 to cover the entire side wall area of ​​the heat sink L1, thereby effectively increasing the heat dissipation area of ​​the radiator L.

[0050] It should be noted that the installation height of the side wall nozzle 5 can be flexibly adjusted according to actual conditions. For example, each side wall nozzle 5 is arranged at 1 / 3 of the height of the side wall of the radiator L, and its spraying water flow can effectively cover the high oil temperature area of ​​the four surrounding heat sinks L1.

[0051] In the embodiment of the present invention, the spray cooling device further includes a second auxiliary pipe 6 and an environmental nozzle 7; wherein a second mounting hole (not shown) for mounting the second auxiliary pipe 6 is provided on the main pipe 1; the second mounting hole is a through hole and is arranged close to the water valve 3;

[0052] The second auxiliary pipe 6 is a PVC pipe, one end of which is installed in the second mounting hole on the main pipe 1 and communicates with the second mounting hole, and the other end is arranged away from the radiator L and is installed with an environmental nozzle 7;

[0053] The environmental nozzle 7 is a plastic or metal nozzle, and is provided with at least one group of third water spray holes (not shown); each group of third water spray holes is composed of a plurality of through holes arranged axially or radially around the connected second auxiliary pipe 6.

[0054] At this time, by adding a second auxiliary pipe 6 and an environmental nozzle 7 in the spray cooling device to cool the surrounding environment of the radiator L, spraying the surrounding environment is achieved to reduce the overall temperature of the surrounding environment of the transformer, thereby further improving the spray cooling effect.

[0055] It can be seen that through the multi-zone spray layout, the radiator L is cooled by three-dimensional spraying from the top, side walls and surrounding environment, which greatly increases the coverage area of ​​the spray water film on the surface of the radiator L and improves the spray cooling effect.

[0056] In the embodiment of the present invention, the water inlet end of the main pipeline 1 is controlled to form a water circuit, so the spray cooling device also includes an automatic self-priming pump 8, a pre-filter 9 and a filter angle valve 10; wherein,

[0057] The automatic self-priming pump 8 is arranged on the main pipeline 1, close to the water valve 3 and located on the side of the water valve 3 away from the radiator L;

[0058] The filter angle valve 10 is arranged on the main pipeline 1 and is close to the water inlet of the main pipeline 1;

[0059] The pre-filter 9 is arranged on the main pipeline 1 and is located between the automatic self-priming pump 8 and the filter angle valve 10 .

[0060] In the embodiment of the present invention, if the water valve 3 is a mechanical water valve, the spray cooling device is controlled manually. In order to realize automatic control of the spray cooling device, the water valve 3 is improved to an electromagnetic water valve, and the electromagnetic water valve needs an electrical control circuit to control it. Therefore, the electromagnetic water valve is controlled to start and stop by a preset electrical control circuit.

[0061] At this time, in order to facilitate management, the electrical control circuit and the water circuit are installed in the same cabinet (such as a local control cabinet for water spray cooling), that is, the electrical control circuit, the electromagnetic water valve, the automatic self-priming pump 8, the pre-filter 9 and the filter angle valve 10 are installed in the same cabinet, such as Figure 2 shown.

[0062] At this time, the cabinet is designed and manufactured according to the standard cabinet of the substation, which is a wall-mounted cabinet or a floor-standing cabinet; the cabinet is sealed and equipped with a temperature and humidity sensor (not shown) and an anti-condensation device (not shown). For example, the cabinet is fixed on the wall, and the grounding wire is used for reliable grounding. The cabinet door is equipped with a water-blocking sealing strip. The interface of the cabinet wire trough is sealed with black glue, and the waterproof and dustproof sealing performance is good. A temperature and humidity sensor is installed in the cabinet. When the temperature and humidity reach the set threshold, the heating plate (i.e., the anti-condensation device) is turned on for moisture-removing heating.

[0063] At this time, the electrical control circuit in the cabinet is connected to the electromagnetic water valve, which is used to form a corresponding start or stop instruction according to one of the remote control instructions, on-site control instructions, time parameters and temperature parameters, and automatically start and stop the electromagnetic water valve.

[0064] The electrical control circuit includes a control device 11 and a controller 12; wherein,

[0065] One end of the control device 11 is connected to the electromagnetic water valve, and the other end is connected to the controller 12, and is used to automatically start and stop the electromagnetic water valve according to the start or stop command issued by the controller;

[0066] The controller 12 is used to generate a corresponding start or shut down instruction according to one of the remote control instruction, the on-site control instruction, the time parameter and the temperature parameter and send it to the control device.

[0067] The controller 12 includes a manual start controller 121, a remote control controller 122, a time controller 123 and a temperature controller 124;

[0068] The manual start controller 121 is used to generate a corresponding start or close instruction based on the on-site control instruction input by the user and send it to the control device to realize the on-site manual control of the opening or closing of the electromagnetic water valve;

[0069] The remote control controller 122 is used to generate a corresponding start or close command based on the remote control command input by the user and send it to the control device to realize the remote control of the electromagnetic water valve to open or close;

[0070] The time controller 123 is used to determine the start time and the close time based on the built-in time parameters, and when the start time or the close time is reached, generate a corresponding start or close instruction and send it to the control device to realize automatic control of the opening or closing of the electromagnetic water valve;

[0071] The temperature controller 124 is connected to a temperature sensor (such as Figure 1 The temperature sensor S is used to determine the start-up temperature and the shut-down temperature based on the built-in temperature parameters, and when it is determined that the real-time temperature collected by the temperature sensor reaches the start-up temperature or the shut-down temperature, a corresponding start-up or shut-down instruction is generated and sent to the control device to automatically control the opening or closing of the electromagnetic water valve. It should be noted that the temperature sensor S is placed on the oil inlet pipe of the transformer radiator L, and is installed in an annular surface mount manner to be close to the surface of the oil inlet pipe to obtain an accurate oil temperature value.

[0072] It can be seen that the manual start controller can manually control the opening or closing of the electromagnetic water valve on-site; the temperature controller is used to receive the temperature value measured by the temperature sensor, and compare it with the oil temperature obtained by the temperature sensor to control the opening or closing of the electromagnetic water valve; the time controller can set the start and stop time, and control the opening or closing of the electromagnetic water valve according to the set time; the remote control controller is used to connect to the remote terminal unit (RTU) and receive the control command issued by the user at the remote control terminal to control the opening or closing of the electromagnetic water valve.

[0073] In an example, Figure 3 As shown, three control modes are adopted, including switching between manual control mode, automatic control mode and remote control mode.

[0074] After selecting the manual control mode, the start and stop of the spray cooling device can be controlled locally.

[0075] After selecting the automatic control mode, if you need to put the spray cooling device into operation after the transformer oil temperature reaches a certain threshold, you can set it to the temperature automatic control mode. If you need to start and stop the spray cooling device at a fixed time every day, you can set it to the time automatic control mode. In the temperature automatic control mode, the spray cooling device compares the real-time collected oil temperature value with the set threshold, and automatically completes the start and stop of the spray cooling device after the set condition is reached. Multiple temperature sensors can be set and controlled according to the "AND" or "OR" logic. In order to avoid the oil temperature shaking near a certain value, causing the water pump and electromagnetic water valve to be damaged due to frequent operation, the start threshold and the shutdown threshold need to set a hysteresis interval. In the time automatic control mode, you can set parameters such as the start and stop time and the start and stop cycle, and the spray cooling device will automatically operate according to the time control parameters.

[0076] After selecting the remote control mode, you can send instructions on the remote control terminal to control the start and stop of the spray cooling device.

[0077] Implementing the embodiments of the present invention has the following beneficial effects:

[0078] 1. The present invention arranges the main pipeline in the spray cooling device below the radiator, and arranges a plurality of first auxiliary pipelines connected to the main pipeline and equipped with top nozzles and side wall nozzles between different radiating fins of the radiator, so that water flows through the top nozzles and side wall nozzles of each first auxiliary pipeline to cool down different parts of the radiator and the radiating fins, thereby improving the spray cooling effect;

[0079] 2. The present invention uses the top nozzles of each first auxiliary pipe in the spray cooling device to scatter the water flow in a vertical disk shape and the side wall nozzles to scatter the water flow in a vertical disk shape, which can not only meet the cooling effect of the water flow on the top of the radiator, but also allow the water flow to flow from top to bottom along the heat sink to effectively increase the cooling area of ​​the radiator, thereby further improving the spray cooling effect; at the same time, the spray cooling device also adds a second auxiliary pipe and an environmental nozzle to cool the surrounding environment of the radiator, further improving the spray cooling effect;

[0080] 3. The present invention uses an electrical control circuit to intelligently control the electromagnetic water valve in the spray cooling device, including local manual control, remote control, time control and temperature control, thereby enhancing practicality and reducing waste of resources and manpower.

[0081] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
