Description

Technical Field

[0001] This utility model belongs to the technical field of power engineering technology, specifically relating to an installation structure for an intelligent phase comparison device for a ring main unit. Background Technology

[0002] Environmentally friendly ring main units are normally powered by a single source. However, in critical power applications, dual power supplies are typically used to ensure reliability. To guarantee the safety of the distribution network, after the first power supply is successfully connected, the frequency, voltage amplitude, and phase angle of the second power supply must be within acceptable error ranges before it can be connected. A phase comparator is installed on the ring main unit's panel. This comparator checks the phase comparability of the two power supplies and can provide feedback on the phase comparability by sending remote signals to the master station.

[0003] In existing technologies, since the phase comparator is a post-installation device after the ring main unit is manufactured, it is usually installed by fixing a mounting bracket with a designated mounting position for the phase comparator to the panel with bolts, and then fixing the phase comparator to the mounting bracket. However, this installation method requires tightening bolts at multiple points when fixing the phase comparator, resulting in low installation efficiency; furthermore, the phase comparator is not easy to disassemble and replace after inspection and maintenance, which also leads to low disassembly efficiency. Utility Model Content

[0004] This utility model provides an installation structure for an intelligent phase comparison device for a ring network box, which aims to improve the installation and disassembly efficiency of the phase comparison device on the ring network box panel.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An intelligent phase comparison device installation structure for a ring main unit is provided, comprising a housing, a mounting frame, and multiple limiting components; the housing is used to hold the phase comparison device and insert it into the mounting hole on the electrical box panel; one end of the housing has a stepped surface that abuts against the outer surface of the electrical box panel; the mounting frame is sleeved on the housing, and multiple push plates are slidably arranged on the mounting frame, each push plate abutting against the inner surface of the electrical box panel; the mounting frame has multiple uprights; each limiting component is spaced apart on the side wall of the housing, and each limiting component is used to engage with each upright to limit the distance between the mounting frame and the electrical box panel.

[0006] In one possible implementation, the mounting frame includes two vertically corresponding mounting frames connected as one unit by uprights located at their corners, forming a mounting space between the two mounting frames suitable for the housing to pass through.

[0007] In some embodiments, a first through hole is provided horizontally on the side of the mounting frame near the electrical box panel, and a push plate is provided in the mounting frame, which slides against the inner wall of the first through hole.

[0008] For example, both mounting frames are provided with a second through hole vertically, and a rotating rod is inserted into both second through holes and rotates in cooperation with the rotating rod.

[0009] For example, two first gears are spaced apart on the rotating rod.

[0010] For example, a second gear is rotatably mounted on the mounting frame, and a rack is provided on the push plate. The second gear is meshed with the rack, and the first gear is meshed with the second gear.

[0011] In some embodiments, a crank handle is provided at one end of the lever.

[0012] In one possible implementation, the sidewall of the housing is provided with multiple mounting slots, and each limiting component is respectively located in each mounting slot.

[0013] In some embodiments, the limiting assembly includes a fixed rod, a rotating plate, and a limiting member; the fixed rod is vertically disposed in the mounting groove, and both ends are connected to the mounting groove; one end of the rotating plate is rotatably connected to the fixed rod, and the other end rotates out of the mounting groove and is engaged with the side of the column near the electrical box panel; the limiting member is disposed at the opening of the mounting groove, and when the rotating plate rotates to engage with the column, the limiting member abuts against the rotating plate.

[0014] For example, a torsion spring is fitted onto the fixed rod, and the torsion spring is connected to the rotating plate.

[0015] The beneficial effects of the intelligent phase comparison device installation structure for ring main units provided by this utility model are as follows: Compared with the prior art, this utility model uses a stepped surface at one end of the housing to abut against the outer surface of the electrical box panel, and a push plate on the mounting bracket to abut against the inner surface of the electrical box panel. The push plate pushes the electrical box panel and clamps it with the stepped surface. The housing is equipped with multiple limiting components, which respectively engage with the columns on the mounting bracket. The limiting components engaging with the columns prevent the mounting bracket from moving away from the electrical box panel, thus achieving clamping of the electrical box panel by the push plate and the stepped surface. The mounting bracket engaging with the limiting components prevents it from moving away from the electrical box panel and, under the pushing action of the push plate, clamps the electrical box panel with the stepped surface, allowing the housing to be quickly fixed in the mounting holes of the electrical box panel. During maintenance of the phase comparison device, the mounting bracket can be separated from the housing to achieve rapid disassembly of the phase comparison device, improving installation and disassembly efficiency.

[0025] Please refer to the following: Figure 1 and Figure 2The installation structure of the intelligent phase comparison device for ring network boxes provided by this utility model is described below. The installation structure of the intelligent phase comparison device for ring network boxes includes a housing 10, a mounting frame 20, and multiple limiting components 30. The housing 10 is used to hold the phase comparison device and insert it into the mounting hole on the electrical box panel 40. One end of the housing 10 has a stepped surface 11, which abuts against the outer surface of the electrical box panel 40. The mounting frame 20 is sleeved on the housing 10. Multiple push plates 21 are slidably provided on the mounting frame 20, and each push plate 21 abuts against the inner surface of the electrical box panel 40. The mounting frame 20 has multiple columns 22. Each limiting component 30 is spaced apart on the side wall of the housing 10. Each limiting component 30 is used to engage with each column 22 to limit the distance between the mounting frame 20 and the electrical box panel 40.

[0026] It should be noted that the housing 10 has a circuit board inside, which can complete the acquisition and analysis of power phase information and transmit signals to the main station; the housing 10 has multiple terminals on the outside, which can connect the circuit voltage signal to the circuit board. The housing 10 is the same size as the mounting hole, which can prevent the housing 10 from shaking when it is installed on the electrical box panel 40; the area of ​​the stepped surface 11 is larger than the opening area of ​​the mounting hole. After the housing 10 is inserted into the mounting hole, the stepped surface 11 abuts against the outer surface of the electrical box panel 40. At this time, the mounting bracket 20 is sleeved on the housing 10 on the side away from the stepped surface 11. The mounting bracket 20 is pushed along the housing 10 to be close to the electrical box panel 40. The push plate 21 slides out of the mounting bracket 20 and abuts against the inner surface of the electrical box panel 40. When the mounting bracket 20 moves away from the electrical box panel 40, the limiting component 30 engages with the column 22 to prevent the mounting bracket 20 from moving away from the electrical box panel 40. The push plate 21 and the stepped surface 11 cooperate to clamp the electrical box panel 40.

[0027] The beneficial effects of the intelligent phase comparison device installation structure for ring main units provided by this utility model are as follows: Compared with the prior art, this utility model uses a stepped surface 11 at one end of the housing 10 to abut against the outer surface of the electrical box panel 40, and a push plate 21 on the mounting frame 20 to abut against the inner surface of the electrical box panel 40. The push plate 21 pushes the electrical box panel 40 and clamps the electrical box panel 40 in conjunction with the stepped surface 11. The housing 10 is provided with multiple limiting components 30, which respectively engage with each column 22 on the mounting frame 20. The limiting components 30 engaging with the columns 22 can prevent the mounting frame 20 from moving away from the electrical box panel 40, thus realizing the clamping of the electrical box panel 40 by the push plate 21 in conjunction with the stepped surface 11. The mounting bracket 20 engages with the limiting component 30 to prevent it from moving away from the electrical box panel 40. Under the pushing action of the push plate 21, it can work with the stepped surface 11 to clamp the electrical box panel 40, allowing the housing 10 to be quickly fixed in the mounting hole of the electrical box panel 40. When the phase comparator is being repaired, the mounting bracket 20 can be separated from the housing 10 to achieve quick disassembly of the phase comparator, which can improve the efficiency of installation and disassembly.

[0028] In one possible implementation, please refer to Figure 3 The mounting frame 20 includes two mounting frames 23 that are corresponding to each other. The two mounting frames 23 are connected as one unit by each column 22 located at their corners. An installation space suitable for the housing 10 to pass through is formed between the two mounting frames 23.

[0029] It should be noted that when the mounting bracket 20 is fitted onto the housing 10, the upper and lower surfaces of the housing 10 slide against the two mounting frames 23 respectively, preventing vertical displacement between the housing 10 and the mounting bracket 20 during installation and reducing installation difficulty. The two mounting frames 23 not only fix the housing 10 but also protect it, preventing damage when switching the electrical box on or off.

[0030] In some embodiments, please refer to Figure 3 and Figure 4 The mounting frame 23 has a first through hole 231 on the side near the electrical box panel 40. The mounting frame 23 has a push plate 21, which slides against the inner wall of the first through hole 231.

[0031] It should be noted that the push plate 21 is located inside the mounting frame 23 and can slide horizontally out of the mounting frame from the first through hole 231 to abut against the inner surface of the electrical box panel 40. The side of the push plate 21 near the electrical box panel 40 is provided with a rubber strip so that the push plate 21 can flexibly contact the inner surface of the electrical box panel 40, avoiding excessive force between the push plate 21 and the inner surface of the electrical box panel 40, which could damage the inner surface of the electrical box panel 40.

[0032] For examples, please refer to Figure 3 and Figure 4 Both mounting frames 23 are vertically provided with second through holes 232, and rotating rods 24 are inserted into the two second through holes 232 and rotate in cooperation with the rotating rods 24.

[0033] It should be noted that the two ends of the rotating rod 24 are respectively inserted into the second through holes 232 on the two mounting frames 23 and rotate to fit against the inner wall of the second through holes 232.

[0034] For example, please refer to Figure 4 and Figure 5 Two first gears 241 are spaced apart on the rotating rod 24.

[0035] It should be noted that the rotating rod 24 can serve as the driving end of the push plate 21, and by driving the first gear 241 to rotate, the push rod can slide within the mounting frame 23.

[0036] For example, please refer to Figure 4A second gear 233 is rotatably mounted on the mounting frame 23, and a rack 211 is provided on the push plate 21. The second gear 233 is meshed with the rack 211, and the first gear 241 is meshed with the second gear 233.

[0037] It should be noted that the second gear 233 is rotatably located inside the mounting frame 23, and the push plate 21 is provided with a rack 211. The second gear 233 controls the push plate 21 to reciprocate inside the mounting frame 23 by rotating clockwise and counterclockwise. When the mounting bracket 20 is fitted onto the housing 10 and pushed close to the electrical box panel 40, the push plate 21 is located inside the mounting frame 23. The mounting bracket 20 is pushed to the designated position. The second gear 233 rotates to make the push plate 21 slide out of the mounting frame and abut against the inner surface of the electrical box panel 40. The push plate 21 pushes the mounting bracket 20 away from the electrical box panel 40 and makes the column 22 and the limiting component 30 engage with each other, so as to realize the installation and fixation of the housing 10 in the mounting hole.

[0038] For example, please refer to Figure 3 and Figure 4 Two first gears 241 are spaced apart on the rotating rod 24 and mesh with the second gears 233 inside the two mounting frames 23 respectively. The rotating rod 24 drives the two second gears 233 to rotate, which drives the two push plates 21 to slide out of the mounting frame 23, so that the two push plates 21 push the electrical box panel 40 together. The two push plates 21 are located above and below the housing 10 respectively. When pushing the electrical box panel 40, the housing 10 is kept vertically balanced and prevented from tilting. A third through hole can be provided on the side wall of the mounting frame 23. The first gear 241 is located in the third through hole, and a positioning pin is provided at the opening of the third through hole. When the rotating rod 24 rotates and drives the push plates 21 to push the inner surface of the electrical box panel 40 and clamp the electrical box panel 40 with the stepped surface 11, the positioning pin locks the first gear 241, realizing the installation and fixation of the housing 10 on the electrical box panel 40.

[0039] In some embodiments, please refer to Figure 4 and Figure 5 One end of the rotating rod 24 is provided with a rocker handle 242.

[0040] It should be noted that the operator manipulates the rotating rod 24 to rotate by the crank handle 242. After the operator pushes the mounting bracket 20 close to the electrical box panel 40, the operator rotates the crank handle 242 to make the push plate 21 slide out of the mounting frame 23 and abut against the inner surface of the electrical box panel 40.

[0041] In one possible implementation, please refer to Figure 6 The side wall of the housing 10 is provided with multiple mounting slots 12, and each limiting component 30 is respectively located in each mounting slot 12.

[0042] It should be noted that each limiting component 30 is located in each mounting slot 12. When the mounting bracket 20 is fitted onto the housing 10 and pushed close to the electrical box panel 40, the limiting component 30 is prevented from blocking the installation between the mounting bracket 20 and the housing 10.

[0043] In some embodiments, please refer to Figure 6 The limiting component 30 includes a fixed rod 31, a rotating plate 32, and a limiting member 33. The fixed rod 31 is vertically installed in the mounting groove 12, and both ends are connected to the mounting groove 12. One end of the rotating plate 32 is rotatably connected to the fixed rod 31, and the other end rotates out of the mounting groove 12 and is engaged with the side of the column 22 near the electrical box panel 40. The limiting member 33 is installed at the opening of the mounting groove 12. When the rotating plate 32 rotates to engage with the column 22, the limiting member 33 abuts against the rotating plate 32.

[0044] It should be noted that one end of the rotating plate 32 is rotatably connected to the fixed rod 31. When the rotating plate 32 rotates out of the mounting groove 12, the upper surface of the rotating plate 32 abuts against the limiting member 33, forming an angle between the rotating plate 32 and the side wall of the housing 10. Each column 22 is located within its respective angle, which restricts the movement of the mounting frame 20 and prevents the mounting frame 20 from separating from the electrical box panel 40. When the housing 10 is inserted into the mounting hole, the inner wall of the mounting hole abuts against the upper surface of the rotating plate 32, pushing the rotating plate 32 into the mounting groove 12. This allows the housing 10 to slide within the mounting hole until the stepped surface 11 abuts against the outer surface of the electrical box panel 40. When the rotating plate 32 is located on one side of the inner surface of the electrical box panel 40, the rotating plate 32 will rotate out of the mounting groove 12, preventing the housing 10 from detaching from the electrical box panel 40. When the mounting bracket 20 is fitted onto the housing 10, the column 22 presses against the upper surface of the rotating plate 32 and causes the rotating plate 32 to rotate into the mounting groove 12. When the column 22 separates from the upper surface of the rotating plate 32, the rotating plate 32 rotates out of the mounting groove 12 and abuts against the column 22.

[0045] For example, please refer to Figure 6 A torsion spring 311 is sleeved on the fixed rod 31, and the torsion spring 311 is connected to the rotating plate 32.

[0046] It should be noted that a torsion spring 311 is sleeved on the fixing rod 31. When the rotating plate 32 is rotatably connected to the fixing rod 31, the rotating plate 32 is connected to the torsion spring 311. The torsion spring 311 gives the rotating plate 32 an elastic force to rotate out of the mounting groove 12. In its natural state, the rotating plate 32 will remain in contact with the limiting member 33.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
