Description

Technical Field

[0001] This application relates to the field of electrical equipment installation, and in particular to a high-efficiency reverse adjustment method for high-voltage disconnect switches. Background Technology

[0002] High-voltage disconnect switches are crucial switching devices in the electrical systems of power plants and substations. During the installation of high-voltage power distribution equipment, problems frequently arise where manual closing achieves the required position, but the opening position is either incomplete or incomplete. Construction workers typically adjust the switch arm angle or the connecting rod length gradually to achieve the correct opening and closing position. However, this method requires incremental adjustments, is time-consuming and labor-intensive, and often fails to guarantee the quality of opening and closing. Summary of the Invention

[0003] This application provides a high-efficiency reverse adjustment method for high-voltage disconnect switches, which can solve the problems of time-consuming, labor-intensive, and inefficient adjustment of high-voltage disconnect switches.

[0004] This application provides a high-voltage disconnecting switch reverse-type high-efficiency adjustment method, including the following steps: When the disconnecting switch is not fully open or closed, the operating handle is raised, causing the switch to move. When both the operating handle and the switch are in the half-open / closed position, the raising of the operating handle is stopped. After the operating handle is held in the half-open / closed position, the switch crank arm fixing bolt is loosened, and the switch is manually operated to the closed position, then the switch crank arm fixing bolt is tightened. The operating handle, which is held in the half-open / closed position, is moved to the open position, and the switch moves with the operating handle to the open position. When both the operating handle and the switch are in the open position, it is determined that the switch can be moved to the closed or open position by operating the operating handle, thus achieving the full opening and closing of the disconnecting switch.

[0005] In some embodiments, when it is determined that the switch can be moved to the closed or open position by operating the operating handle, the operation of the operating handle to the open position is stopped.

[0006] In some embodiments, after stopping the operation of the operating handle to the open position, the operating handle is operated to the close position, and the switch moves to the close position along with the operating handle. When both the operating handle and the switch are in the close position, it is verified that the switch can be moved to the close position by operating the operating handle.

[0007] In some embodiments, it is verified that when the switch can be moved to the closed position by operating the operating handle, the operation of the operating handle to the closed position is stopped.

[0008] In some embodiments, after stopping the operation of the operating handle to the closed position, the operating handle is operated to the open position, and the switch moves to the open position along with the operating handle. When both the operating handle and the switch are in the open position, it is verified that the switch can be moved to the open position by operating the operating handle.

[0009] In some embodiments, it is verified that when the switch can be moved to the open position by operating the operating handle, the operation of the operating handle to the open position is stopped, and the disconnecting switch adjustment is completed.

[0010] In some embodiments, after the disconnecting switch is assembled, it is checked whether the disconnecting switch is not fully open or closed. If the disconnecting switch is not fully open or closed, the operating handle is raised, which drives the switch blade. When both the operating handle and the switch blade are in the half-open / closed position, the raising of the operating handle is stopped. After the operating handle is held in the half-open / closed position, the switch crank arm fixing bolt is loosened, and the switch blade is manually operated to the closed position. Then, the switch crank arm fixing bolt is tightened. The operating handle, which is held in the half-open / closed position, is moved to the open position. At the same time, the switch blade moves with the operating handle to the open position. When both the operating handle and the switch blade are in the open position, it is determined that the switch blade can be driven to the closed and open positions by operating the operating handle, thus realizing the disconnecting switch is fully open or closed.

[0011] In some embodiments, the disconnecting switch is assembled in the field.

[0012] In some embodiments, the disconnecting switch is assembled according to the installation diagram provided by the manufacturer.

[0013] In some embodiments, when the disconnecting switch is assembled according to the installation diagram provided by the manufacturer, the angle between the connecting rod and the switch crank arm of the disconnecting switch is the same as the angle shown in the installation diagram.

[0014] A high-voltage disconnector switch reverse-type high-efficiency adjustment method according to an embodiment of this application includes the following steps: When the disconnector switch is not fully open or closed, the operating handle is lifted, and the operating handle drives the switch blade. When both the operating handle and the switch blade are in the half-open / closed position, the lifting of the operating handle is stopped. After the operating handle is held in the half-open / closed position, the switch crank arm fixing bolt is loosened, and the switch blade is manually operated to the closed position, and then the switch crank arm fixing bolt is tightened. The operating handle, which is held in the half-open / closed position, is operated to the open position, and at the same time, the switch blade moves to the open position with the operating handle. When both the operating handle and the switch blade are in the open position, it is determined that the switch blade can be driven to the closed and open positions by operating the operating handle, thus realizing the disconnector switch opening and closing. The high-voltage disconnector switch reverse-type high-efficiency adjustment method of this application is quick to adjust, requires no multiple adjustments, saves time and effort, and solves the problem of time-consuming, labor-intensive, and inefficient adjustment of high-voltage disconnector switches. The high-voltage disconnector switch reverse-type high-efficiency adjustment method of this application is formed in one step, and the switch opening and closing positions can meet the specifications. The high-voltage disconnector switch reverse high-efficiency adjustment method of this application can be applied to the adjustment of various types of high-voltage disconnectors.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] See Figure 1-7 Embodiments of this application provide a high-voltage disconnecting switch reverse high-efficiency adjustment method, including the following steps:

[0025] Step 1, Refer to Figure 5 When the disconnecting switch is not fully open or closed, lift the operating handle 121. The operating handle 121 will drive the knife switch 111. When both the operating handle 121 and the knife switch 111 are in the half-open or half-closed position, stop lifting the operating handle 121.

[0026] In the above steps, after the disconnecting switch is assembled, it is checked whether the disconnecting switch is not fully open or closed. If the disconnecting switch is not fully open or closed, the operating handle 121 is lifted. The operating handle 121 drives the knife switch 111. When both the operating handle 121 and the knife switch 111 are in the half-open or half-closed position, the lifting of the operating handle 121 is stopped.

[0027] Among them, the disconnect switch components were brought to the site, and the construction workers assembled the disconnect switches on site.

[0028] Assemble the disconnect switch according to the installation diagram provided by the manufacturer.

[0029] When assembling the disconnect switch according to the installation diagram provided by the manufacturer, the angle between the connecting rod 13 of the disconnect switch and the switch crank arm should be the same as the angle shown in the installation diagram, and the bolts of each mechanism should be fixed.

[0030] Incomplete opening or closing of a disconnecting switch includes both manual and electric incomplete opening or closing. Of course, electric closing also requires manual adjustment first, followed by electric adjustment.

[0031] See Figure 1 , 2The disconnecting switch consists of an electric brake switch 11 and an operating mechanism 12 connected by a connecting rod 13. The electric brake switch 11 is a GN22-15Z / 5000-63 left-side operating switch, the operating mechanism 12 is a CJZ-2 operating mechanism, and the connecting rod 13 is a 36*5 steel pipe. The disconnecting switch is installed as a whole in a switch cabinet. The switch cabinet uses a welded structure to ensure that the system does not deform during electric operation. The electric brake switch 11 is mounted on the vertical surface 21 of the switch cabinet via a switch mounting beam 14 and a shaft end support 15. The operating mechanism 12 is mounted on the horizontal surface 22 of the switch cabinet. The operating handle 121 is mounted on the operating mechanism 12 via the switch cabinet panel 23. The closing position A and the opening position B of the operating mechanism crank arm 122 form a 90-degree angle.

[0032] Step Two, Refer to Figure 6 After the operating handle 121 is held in the half-open / closed position, loosen the switch crank arm fixing bolt 112, manually operate the switch knife 111 to the closed position, and then tighten the switch crank arm fixing bolt 112.

[0033] Step 3, Refer to Figure 7 The operating handle 121, which is in the half-open / closed position, is operated to the open position. At the same time, the switch 111 moves to the open position along with the operating handle 121. When both the operating handle 121 and the switch 111 are in the open position, it is determined that the switch 111 can be driven to the closed and open positions by operating the operating handle 121, so as to realize the opening and closing of the disconnecting switch.

[0034] In the above steps, once it is determined that the switch 111 can be moved to the closed position and the open position by operating the operating handle 121, the operation of the operating handle 121 to the open position is stopped.

[0035] After stopping the operation of the operating handle 121 to the open position, operate the operating handle 121 to the closed position. Simultaneously, the switch 111 moves with the operating handle 121 to the closed position. When both the operating handle 121 and the switch 111 are in the closed position, it can be verified that the switch 111 can be moved to the closed position by operating the operating handle 121. Refer to [link / reference] when both the operating handle 121 and the switch 111 are in the closed position. Figure 3 .

[0036] The verification can be performed by operating the operating handle 121 to move the switch 111 to the closed position, and then stopping the operation of the operating handle 121 to the closed position.

[0037] After stopping the operation of the operating handle 121 to the closed position, operate the operating handle 121 to the open position. Simultaneously, the switch 111 moves with the operating handle 121 to the open position. When both the operating handle 121 and the switch 111 are in the open position, it can be verified that the switch 111 can be moved to the open position by operating the operating handle 121. Refer to [link / reference] when both the operating handle 121 and the switch 111 are in the open position. Figure 4 .

[0038] The verification can be completed when the switch 111 is moved to the open position by operating the operating handle 121, and then the operation of the operating handle 121 to the open position is stopped, indicating that the disconnecting switch adjustment is complete.

[0039] In one embodiment of this application, the high-voltage disconnector switch reverse high-efficiency adjustment method includes the following steps:

[0040] Step 1: Assemble the disconnect switch on-site according to the installation diagram provided by the manufacturer. The angle between the connecting rod 13 and the switch crank arm of the disconnect switch should be the same as the angle shown in the installation diagram. Secure the bolts of each mechanism. Then, check whether the disconnect switch is not fully open or closed. If the disconnect switch is not fully open or closed, lift the operating handle 121. The operating handle 121 will drive the switch 111. When both the operating handle 121 and the switch 111 are in the half-open / closed position, stop lifting the operating handle 121.

[0041] Step 2: After holding the operating handle 121 in the half-open / closed position, loosen the switch crank arm fixing bolt 112, manually operate the switch knife 111 to the closed position, and then tighten the switch crank arm fixing bolt 112.

[0042] Step 3: Move the operating handle 121, which is currently in the half-open / closed position, to the open position. Simultaneously, the switch 111 moves with the operating handle 121 to the open position. When both the operating handle 121 and the switch 111 are in the open position, it is confirmed that the switch 111 can be moved to the closed and open positions by operating the operating handle 121, thus achieving the opening and closing of the disconnector switch. At the same time, stop moving the operating handle 121 to the open position. Then, move the operating handle 121 to the closed position. Simultaneously, the switch 111 moves with the operating handle 121 to the closed position. When both the operating handle 121 and the switch 111 are in the closed position, it is verified that the switch 111 can be moved to the closed position by operating the operating handle 121. At the same time, stop moving the operating handle 121 to the closed position. Next, operate the operating handle 121 to the open position. At the same time, the switch 111 moves to the open position along with the operating handle 121. When both the operating handle 121 and the switch 111 are in the closed position, it can be verified that the switch 111 can be moved to the open position by operating the operating handle 121. At the same time, stop operating the operating handle 121 to the open position. The disconnecting switch adjustment is complete.

[0043] In summary, the high-voltage disconnector switch reverse-type high-efficiency adjustment method of this application is quick and requires no multiple adjustments, saving time and effort. This method achieves a one-time setup, ensuring the switch's open and closed positions meet specifications. Furthermore, this method is applicable to the adjustment of various types of high-voltage disconnectors.

[0044] In other words, the high-voltage disconnector switch reverse high-efficiency adjustment method of this application can quickly and efficiently complete the disconnector switch adjustment work, achieve high-voltage disconnector switch high-efficiency adjustment, improve construction efficiency, and at the same time ensure the switch contact quality.
