Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a power regulation device. Background Technology

[0002] Power regulation equipment is electrical equipment used to regulate one or more electrical energy parameters (such as voltage, current, frequency, phase, waveform, etc.) in a power system to ensure that electrical energy meets specific load requirements or grid operation standards. Examples include frequency converters and transformers, which are key equipment in modern industrial and commercial facilities. Power units are the core components of power regulation equipment responsible for the conversion, regulation, and control of electrical energy forms (voltage, current, frequency), such as the inverter circuit of a frequency converter and the transformer coils of a transformer. Power units generate a large amount of heat during operation. To ensure stable operation within a safe temperature range and prevent performance degradation, component aging, or even permanent damage due to overheating, some power regulation equipment is equipped with heat exchangers. Coolant supplied through circulating pipelines in the heat exchanger cools the power unit. However, the presence of these pipelines can hinder the maintenance and repair of power regulation equipment. Utility Model Content

[0003] In view of this, in order to solve the problem that the existence of the above-mentioned pipelines will cause certain obstacles to the maintenance and repair of power regulating equipment, this utility model provides a new power regulating equipment that uses a flexible hose as a branch pipe. It can utilize the deformable characteristics of the hose to provide a larger operating space for the maintenance and repair of power regulating equipment, and effectively reduce the obstacles caused by the liquid supply pipeline to the maintenance and repair of power regulating equipment.

[0004] This utility model provides a power regulation device, including: a cabinet, a liquid supply pipe, and a power unit, wherein the liquid supply pipe and the power unit are located inside the cabinet; the liquid supply pipe includes a main pipe, a branch pipe, and a first connecting joint; a first end of the branch pipe is connected to the main pipe, a second end of the branch pipe is connected to a first part of the first connecting joint, a first part of the first connecting joint is connected to a second part of the first connecting joint, and the second part of the first connecting joint is connected to the heat exchanger of the power unit; wherein the branch pipe is a deformable flexible hose, and the second end of the branch pipe can be sealed when the first part is disconnected from the second part.

[0005] In some alternative embodiments, the main pipeline includes a plurality of second connection joints and a plurality of sub-pipe segments, with adjacent sub-pipe segments connected by a second connection joint, and the first end of each branch pipeline communicating with a second connection joint.

[0006] In some optional embodiments, the second connector includes an extension perpendicular to the sub-pipe segment, the extension being located on the side of the second connector close to the corresponding first connector, and the first end of the branch pipe communicating with the extension, wherein the first connector corresponding to the second connector is the first connector through which the extension of the second connector is communicated.

[0007] In some alternative embodiments, the power unit includes a housing, and the heat exchanger includes a heat exchange pipe, an inlet end, and an outlet end. The heat exchange pipe is located inside the housing, and both ends of the heat exchange pipe are connected to the inlet end and the outlet end, which are located outside the housing.

[0008] In some alternative embodiments, the cabinet includes a frame structure and mounting plates connected to the frame structure, and the housing is mounted between two of the mounting plates.

[0009] In some optional embodiments, the first side of the housing is adjacent to one of the two mounting plates, and the second side of the housing is adjacent to the other of the two mounting plates; the water inlet is located on the first side, and the water inlet passes through the mounting through hole of the mounting plate adjacent to the first side and is connected to the fixing nut; the water outlet is located on the second side, and the water outlet passes through the mounting through hole of the mounting plate adjacent to the second side and is connected to the fixing nut.

[0010] In some alternative embodiments, the power conditioning device further includes a conductive busbar electrically connected to the power unit, the conductive busbar being a deformable flexible busbar.

[0011] In some alternative embodiments, the connection terminal on the power unit that is electrically connected to the conductive busbar is located on the portion of the power unit near the cabinet door.

The branch pipe is a deformable flexible hose, and when the first part is disconnected from the second part, the second end of the branch pipe can be sealed. Using a flexible hose as the branch pipe provides greater operating space for the maintenance and repair of the power regulating equipment by utilizing the hose's deformability.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "communication," and "fixation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] As mentioned earlier, the power unit is the core component of the power regulation equipment, such as the inverter circuit and transformer coil. During operation, it generates a lot of heat. In order to ensure that the equipment operates stably within the safe temperature range and to prevent performance degradation, component aging or even permanent damage caused by overheating, some power regulation equipment is equipped with a heat exchanger. The coolant supplied through the circulating liquid supply pipeline of the heat exchanger is used to cool the power unit. However, the existence of the relevant pipeline will cause certain obstacles to the maintenance and repair of the power regulation equipment.

[0030] In this embodiment of the invention, the power regulating equipment includes a cabinet, a liquid supply pipe, and a power unit, with the liquid supply pipe and power unit located inside the cabinet. The liquid supply pipe includes a main pipe, branch pipes, and a first connecting joint. The first end of the branch pipe is connected to the main pipe, the second end of the branch pipe is connected to the first part of the first connecting joint, the first part of the first connecting joint is connected to the second part of the first connecting joint, and the second part of the first connecting joint is connected to the heat exchanger of the power unit. The branch pipe is a deformable flexible hose, and when the first part is disconnected from the second part, the second end of the branch pipe can be sealed. Using a flexible hose as the branch pipe provides greater operating space for the maintenance and repair of the power regulating equipment by utilizing the hose's deformability. During maintenance or repair, the flexible branch pipe can be easily bent, pried open, or temporarily moved from its original position, thus freeing up valuable operating space for the operator's hands, tools, or the target components to be disassembled, avoiding bumps or damage to the components inside the power regulating equipment, and effectively reducing the obstruction caused by the liquid supply pipe to the maintenance and repair of the power regulating equipment. Furthermore, by setting the first part to seal the second end of the branch pipe when disconnected from the second part, when a power unit needs to be disassembled during maintenance and repair, only the first part of the first connection joint corresponding to the power unit needs to be disconnected. The port of the branch pipe can be automatically sealed after the first part is disconnected, preventing coolant from leaking from the main pipe. This achieves isolated maintenance of a single power unit without having to drain the coolant from the entire supply pipe, simplifying the maintenance and repair process of the power regulating equipment and reducing maintenance and repair costs.

[0031] The following is in conjunction with the appendix Figure 1-4 The power regulating device provided in this utility model example will be described below. It should be noted that the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this utility model; they are not necessarily drawn to scale.

[0032] like Figure 1As shown, the power regulating device 100 includes a cabinet 110, a coolant supply pipe 120, and a power unit 130, with the coolant supply pipe 120 and power unit 130 located within the cabinet 110. The coolant supply pipe 120 includes a main pipe 121, a branch pipe 122, and a connecting joint. The main pipe 121 can be connected to a coolant supply source, such as a water tank or pool for storing coolant, to facilitate obtaining or discharging coolant from or to the supply source. The first end of the branch pipe 122 is connected to the main pipe 121, and the second end of the branch pipe 122 is connected to the first part of the first connecting joint 123. The first part of the first connecting joint 123 is connected to the second part of the first connecting joint 123, and the second part of the first connecting joint 123 is connected to the heat exchanger of the power unit 130. The connection in this invention can be a direct connection or an indirect connection through intermediate pipes or pipe joints; the details regarding connection will not be repeated below.

[0033] Any one of the main pipe 121, branch pipe 122 and connecting joint of the liquid supply pipe 120 can be connected to a water pump, thereby driving the coolant to circulate in the heat exchanger of the power unit 130 and carrying away the heat generated by the power unit 130.

[0034] Branch pipe 122 is a deformable flexible hose, such as a metal hose or rubber hose, which allows the branch pipe 122 to be bent and moved during the maintenance and repair of the power conditioning equipment 100, eliminating or reducing obstruction of the operator's view or the target component to be maintained or repaired. It should be understood that the length of the branch pipe 122 may exceed the minimum length required for its connection between the main pipe 121 and the first connection joint 123 between the main pipe 121 and the heat exchanger, allowing for bending and movement. The main pipe 121 can be a rigid pipe, such as copper, aluminum, or PVC (polyvinyl chloride) pipe, to facilitate support for the branch pipe 122.

[0035] The power regulating device 100 of this utility model embodiment can be a frequency converter, and the power unit 130 is a component in the frequency converter used to realize functions such as rectification, filtering and inversion. It may include a rectifier bridge, capacitor bank, inverter circuit, etc. For details, please refer to the relevant technology, which will not be repeated here.

[0036] When the first portion of the first connecting joint 123 is disconnected from the second portion, it can seal the second end of the branch pipe 122. Similarly, in some alternative embodiments, when the second portion is disconnected from the first portion, it can also seal the port where the heat exchanger connects to the second portion. Alternatively, when the second portion is disconnected from the first portion, the port where the heat exchanger connects to the second portion may not be sealed. In this case, the second portion can be located above the heat exchanger to prevent the coolant from flowing out of the heat exchanger from the second portion. Optionally, the first connecting joint 123 can be a self-sealing quick-connect coupling, where the first portion is the self-sealing part of the self-sealing quick-connect coupling. Exemplarily, the first connecting joint 123 can be a bidirectional self-sealing quick-connect coupling / bidirectional self-sealing quick-connect coupling, where the first portion and the second portion of the first connecting joint 123 are two detachable ports of the bidirectional self-sealing quick-connect coupling, such as a male union and a female union. The first portion and the second portion can respectively seal their respective connected pipes or ports. The specific structures of self-sealing quick-connect couplings and bidirectional self-sealing couplings can be found in related technologies and will not be repeated here. Of course, the first connecting connector 123 can also be other types of connectors, and this utility model does not limit this.

[0037] In this embodiment of the invention, the power regulating device 100 includes a cabinet 110, a liquid supply pipe 120, and a power unit 130, with the liquid supply pipe 120 and power unit 130 located within the cabinet 110. The liquid supply pipe 120 includes a main pipe 121, a branch pipe 122, and a first connecting joint 123. The first end of the branch pipe 122 is connected to the main pipe 121, the second end of the branch pipe 122 is connected to the first part of the first connecting joint 123, the first part of the first connecting joint 123 is connected to the second part of the first connecting joint 123, and the second part of the first connecting joint 123 is connected to the heat exchanger of the power unit 130. The branch pipe 122 is a deformable flexible hose; when the first part is disconnected from the second part, the second end of the branch pipe 122 can be sealed. Using a flexible hose as the branch pipe 122 provides greater operating space for the maintenance and repair of the power regulating device 100 by utilizing the hose's deformability. During maintenance or repair, the branch pipe 122, using a flexible hose, can be easily bent, pried open, or temporarily moved from its original position, thus freeing up valuable operating space for the operator's hands, tools, or the target components to be disassembled. This avoids bumping or damaging components within the power regulating equipment 100 and effectively reduces the obstruction caused by the liquid supply pipe 120 to the maintenance and repair of the power regulating equipment 100. Furthermore, by setting the first part to be disconnected from the second part, the second end of the branch pipe 122 can be sealed. This means that when a power unit 130 needs to be disassembled during maintenance or repair, only the first part of the first connecting joint 123 corresponding to that power unit 130 needs to be disconnected. The branch pipe 122 port automatically seals after the first part is disconnected, preventing coolant leakage from the main pipe 121. This achieves isolated maintenance of a single power unit 130 without draining the entire liquid supply pipe 120, simplifying the maintenance and repair process of the power regulating equipment 100 and reducing maintenance and repair costs.

[0038] like Figure 2 As shown, in some optional embodiments, the main pipe 121 includes a plurality of second connecting joints 124 and a plurality of sub-pipe segments 1211, with two adjacent sub-pipe segments 1211 connected by a second connecting joint 124, and the first end of each branch pipe 122 communicating with a second connecting joint 124.

[0039] The second connection joint 124 may include at least two interconnected ports, one of which is connected to the first end of the branch pipe 122, and the other port is connected to the sub-pipe segment 1211. Exemplarily, the second connection joint 124 located at the end of the main pipe segment may include two interconnected ports, one of which is connected to the first end of the branch pipe 122, and the other port is connected to the sub-pipe segment 1211. The second connection joint 124 located between two adjacent sub-pipe segments 1211 may include three interconnected ports, one of which is connected to the first end of the branch pipe 122, and the other two ports are each connected to a sub-pipe segment 1211. At least one of the multiple sub-pipe segments 1211 is connected to a coolant supply source.

[0040] In this embodiment of the invention, the main pipeline 121 includes multiple second connecting joints 124 and multiple sub-pipe segments 1211. Adjacent sub-pipe segments 1211 are connected by a second connecting joint 124, and the first end of each branch pipeline 122 is connected to a second connecting joint 124. Dividing the main pipeline 121 into multiple sub-pipe segments 1211 and connecting them with second connecting joints 124 improves the flexibility of the main pipeline 121 installation and reduces installation difficulty. Furthermore, if a sub-pipe segment 1211 or a second connecting joint 124 is damaged, only the damaged sub-pipe segment 1211 or second connecting joint 124 needs to be replaced, without replacing the entire main pipeline 121, thereby reducing maintenance costs.

[0041] like Figure 2 As shown, in some optional embodiments, the second connector 124 includes an extension 1241 perpendicular to the sub-pipe segment 1211. The extension 1241 is located on the second connector 124 near the corresponding first connector 123. The first end of the branch pipe 122 communicates with the extension 1241. The first connector 123 corresponding to the second connector 124 is the first connector 123 that is communicated by the extension 1241 of the second connector 124 through the branch pipe 122.

[0042] The second connecting joint 124 may include a joint body 1242 and an extension 1241 that are perpendicular to each other. The joint body 1242 may communicate with a sub-pipe section 1211 of the main pipe section, and the extension 1241 may communicate with a first end of a branch pipe 122. The second end of the branch pipe 122 may communicate with a first portion of the first connecting joint 123. The extension 1241 may be located on the side of the joint body 1242 close to the first connecting joint 123. The opening of the extension 1241 may also face the direction of the first connecting joint 123 relative to the joint body 1242.

[0043] In this embodiment of the present invention, the second connecting joint 124 includes an extension 1241 perpendicular to the sub-pipe segment 1211. The extension 1241 is located on the side of the second connecting joint 124 close to the corresponding first connecting joint 123. The first end of the branch pipe 122 is connected to the extension 1241, which allows the extension 1241 to be directly led out from the side of the second connecting joint close to the corresponding first connecting joint 123. Compared with other lead-out positions, the branch pipe 122 can be connected to the first connecting joint 123 with a shorter path, thereby reducing the required length of the branch pipe 122, reducing material costs, and eliminating unnecessary bends in the branch pipe 122, thus reducing the resistance of the inner wall of the branch pipe 122 to the coolant.

[0044] like Figure 3 As shown, in some optional embodiments, the power unit 130 includes a housing 131, and the electrical components of the power unit 130 may be located within the housing 131. The heat exchanger includes a heat exchange pipe, an inlet end 132, and an outlet end 133. The heat exchange pipe is located within the housing 131, thereby absorbing the heat generated by the power unit 130. The two ends of the heat exchange pipe are connected to the inlet end 132 and the outlet end 133, which are located outside the housing 131. Of course, in other optional embodiments, the power unit 130 may not include the housing 131, and this invention does not limit this possibility.

[0045] The main pipe 121 may include a water supply pipe and a water outlet pipe. The water supply pipe is connected to the water inlet 132 of the heat exchanger of the power unit 130 through a branch pipe 122 and a first connector. The water outlet pipe is connected to the water outlet 133 of the heat exchanger of the power unit 130 through a branch pipe 122 and a first connector, thereby realizing the water inlet and water outlet of the heat exchanger through the water supply pipe and the water outlet pipe.

[0046] In this embodiment of the present invention, the power unit 130 includes a housing 131, and the heat exchanger includes a heat exchange pipe, an inlet end 132, and an outlet end 133. The heat exchange pipe is located inside the housing 131, and both ends of the heat exchange pipe are connected to the inlet end 132 and the outlet end 133, which are located outside the housing 131. The heat exchange pipe can be built inside the housing 131 of the power unit 130, and the inlet end 132 and the outlet end 133 can be placed outside the housing 131 of the power unit 130. This facilitates the connection of the inlet end 132 and the outlet end 133 to the first connecting joint 123, reducing the difficulty of connecting the heat exchange pipe to the main pipe 121.

[0047] like Figure 3As shown, in some optional embodiments, the cabinet 110 includes a frame structure 111 and mounting plates 112 connected to the frame structure 111, with the housing 131 mounted between the two mounting plates 112. It should be understood that the cabinet 110 may also include an outer shell (not shown) mounted outside the frame structure, protecting components such as the liquid supply pipes 120 and power units 130 within it. This outer shell may include a door to facilitate maintenance and repair of the liquid supply pipes 120 and power units 130 within the outer shell.

[0048] By providing two mounting plates 112, it is easier to quickly position the housing 131 of the power unit 130 during installation, thereby improving the installation efficiency of the power unit 130. Furthermore, by mounting the housing 131 of the power unit 130 between the two mounting plates 112, the power unit 130 can be fixed in place using the two mounting plates 112, thus improving the stability of the power unit 130 installation.

[0049] like Figure 3 As shown, in some optional embodiments, the first side of the housing 131 is adjacent to one of the two mounting plates 112, and the second side of the housing 131 is adjacent to the other of the two mounting plates 112. A water inlet 132 is located on the first side, passing through a mounting through-hole in the mounting plate 112 adjacent to the first side and connected to a fixing nut 134; a water outlet 133 is located on the second side, passing through a mounting through-hole in the mounting plate 112 adjacent to the second side and connected to a fixing nut 134.

[0050] By opening mounting through holes on two mounting plates 112, and setting a water inlet 132 on the first side, the water inlet 132 passes through the mounting through hole of the mounting plate 112 adjacent to the first side and is connected to the fixing nut 134; the water outlet 133 is set on the second side, and the water outlet 133 passes through the mounting through hole of the mounting plate 112 adjacent to the second side and is connected to the fixing nut 134. By tightening the fixing nut 134, the housing 131 of the power unit 130 can be fixed together with the mounting plates 112 using the water inlet 132 and the water outlet 133. That is, the installation of the housing 131 of the power unit 130 can be realized by utilizing the structure of the power unit 130 itself, which simplifies the fixing structure involved in the installation of the housing 131 of the power unit 130 and makes the installation of the power unit 130 more concise.

[0051] like Figure 1 and Figure 4 As shown, in some optional embodiments, the power regulating device 100 further includes a conductive bus 140 electrically connected to the power unit 130, the conductive bus 140 being a deformable flexible bus.

[0052] Within the cabinet 110 of the power conditioning equipment 100, the power unit 130 needs to transmit high-current electrical energy to the external circuit via a busbar 140. The existing busbar 140 in the power conditioning equipment 100 is typically a rigid copper busbar, which has a fixed shape after installation and cannot be moved.

[0053] The conductive busbar 140 in this embodiment is a deformable flexible busbar, for example, it can be a copper flexible busbar made of multiple layers of thin copper foil or copper braided strip. One end of it can be connected to the terminal of the power unit 130 by fasteners such as bolts, and the other end can be connected to the conductive busbar of the power regulating device 100 or directly connected to an external circuit by fasteners such as bolts. The length of the conductive busbar 140 can be greater than its minimum required length, so that the conductive busbar 140 has a margin and is easy to install.

[0054] In some alternative embodiments, the conductive bus 140 is detachably connected to the connection end 135 of the power unit 130 by bolts. This allows the conductive bus 140 to be easily installed and removed from the connection end 135 of the power unit 130, which helps to shorten the time required for maintenance and repair of the power unit 130.

[0055] In this embodiment of the utility model, the power regulating device 100 further includes a conductive busbar 140 electrically connected to the power unit 130. The conductive busbar 140 is a deformable flexible busbar, which allows the conductive busbar 140 to be bent and deformed during installation. This allows for a certain installation alignment error between the conductive busbar 140 and the component to be connected. Unlike using a rigid copper busbar, it is not necessary to precisely align the mounting holes of the rigid copper busbar and the component to be connected. Simply bending the flexible conductive busbar 140 is sufficient to adjust and align the mounting holes of the flexible busbar with the mounting holes of the component to be connected. This facilitates the insertion of fasteners into the aligned mounting holes for fixation, significantly reducing the assembly difficulty of the conductive busbar 140 and improving the installation efficiency of the conductive busbar 140.

[0056] In some optional embodiments, the connection terminal 135 on the power unit 130, which is electrically connected to the busbar 140, is located on the portion of the power unit 130 near the door of the cabinet 110. For example, the power unit 130 may be divided into a portion near the door of the cabinet 110 and a portion away from the door of the cabinet 110, and the connection terminal 135 on the power unit 130, which is electrically connected to the busbar 140, may be located on the portion near the door of the cabinet 110.

[0057] In this embodiment of the utility model, by setting the connection end 135 of the power unit 130, which is electrically connected to the conductive bus 140, on the part of the power unit 130 near the cabinet door of the cabinet 110, the conductive bus 140 can be easily installed or removed from the connection end 135 of the power unit 130 after the cabinet door of the cabinet 110 is opened, which can significantly improve the efficiency of maintenance and repair of the power unit 130.

[0058] like Figure 4 As shown, in some optional embodiments, the power unit 130 includes a plurality of connection terminals 135 arranged sequentially and parallel to each other. By setting the plurality of connection terminals 135 of the power unit 130 to a structure that is arranged sequentially and parallel to each other, it is convenient to standardize the parallel connection of the conductive busbars 140, and it is possible to install and fasten the multiple conductive busbars 140 to the connection terminals 135 in a unified direction, thereby improving the assembly efficiency and accuracy of the conductive busbars 140. Of course, the power unit 130 may also include connection terminals 135 other than the plurality of connection terminals 135 arranged sequentially mentioned above, and this embodiment does not limit the arrangement of the connection terminals 135.

[0059] It should be noted that, in this patent application, nouns and pronouns referring to persons are not limited to specific genders. Relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
