Description

Technical Field

[0001] The present application relates to the technical field of switch cabinets, and in particular to an interlocking structure suitable for a removable sealing plate and a switch cabinet. Background Art

[0002] As a key equipment in the power system, the safety of the switchgear is of vital importance. In order to ensure the safety of operators and the stable operation of the power system, the switchgear must meet the strict "five-prevention" interlocking requirements, namely, to prevent the circuit breaker from being opened or closed by mistake; to prevent the disconnector from being pulled or closed under load; to prevent the ground wire from being hung under power; to prevent the disconnector from being closed under power; and to prevent the operator from entering the live compartment by mistake. These requirements ensure that operators will not face the risk of electric shock or equipment damage due to misoperation.

[0003] In this context, the rear cover design of each switch cabinet must strictly comply with the five-protection interlocking regulations. This means that the rear cover can only be opened for maintenance or inspection after confirming that the switch cabinet is not energized. In order to prevent the rear cover from being opened accidentally when the switch cabinet is energized, an electromagnetic lock is usually installed on the rear cover of the switch cabinet. This lock will automatically operate and lock the rear cover when the switch cabinet is energized; when the switch cabinet is in a power-off state, the electromagnetic lock will automatically unlock, allowing the operator to safely open the rear cover.

[0004] However, the traditional electromagnetic lock installation method has some inconveniences. Since the electromagnetic lock and its secondary wires are usually fixed on the rear cover plate, when the rear cover plate needs to be moved, these components will also move with it, which not only increases the difficulty of movement, but also may cause damage to the cables. In actual operation, in order to move the rear cover plate, the staff often need to remove the secondary wiring of the electromagnetic lock first, which not only consumes time, but also increases the risk of breaking the cable due to misoperation during the removal and reconnection process. Summary of the invention

[0031] As a key equipment in the power system, the safety of the switchgear is of vital importance. In order to ensure the safety of operators and the stable operation of the power system, the switchgear must meet the strict "five-prevention" interlocking requirements, namely, to prevent the circuit breaker from being opened or closed by mistake; to prevent the disconnector from being pulled or closed under load; to prevent the ground wire from being hung under power; to prevent the disconnector from being closed under power; and to prevent the operator from entering the live compartment by mistake. These requirements ensure that in any case, the operator will not face the risk of electric shock or equipment damage due to misoperation.

[0032] In this context, the rear cover design of each switch cabinet must strictly comply with the five-protection interlocking regulations. This means that the rear cover can only be opened for maintenance or inspection after confirming that the switch cabinet is not energized. In order to prevent the rear cover from being opened accidentally when the switch cabinet is energized, an electromagnetic lock is usually installed on the rear cover of the switch cabinet. This lock will automatically operate when the switch cabinet is energized, locking the rear cover to prevent the rear cover from being accidentally opened; when the switch cabinet is in a power-off state, the electromagnetic lock will automatically unlock, allowing the operator to safely open the rear cover.

[0033] However, the traditional electromagnetic lock installation method has some inconveniences. Since the electromagnetic lock and its secondary wires are usually fixed on the rear cover plate, when the rear cover plate needs to be moved, these components will also move with it, which not only increases the difficulty of movement, but also may cause damage to the cables. In actual operation, in order to move the rear cover plate, the staff often need to remove the secondary wiring of the electromagnetic lock first, which not only consumes time, but also increases the risk of breaking the cable due to misoperation during the removal and reconnection process.

[0034] In order to solve these problems, an interlocking structure suitable for removable sealing plates was designed. This structure allows the rear sealing plate to be easily moved without removing the secondary wiring, greatly improving work efficiency. The interlocking structure optimizes the installation method of the electromagnetic lock and the design of the rear sealing plate, making the movement of the rear sealing plate more convenient and quick, while avoiding damage to the secondary wiring caused by misoperation, ensuring the safety and reliability of operation.

[0035] This interlocking structure not only improves the maintenance efficiency of the switchgear, but also reduces the operational risks, providing a more solid guarantee for the safe operation of the power system. Through this design, operators can focus more on their work without having to worry too much about safety issues, thereby improving the overall work quality and efficiency. Figure 1-4 The embodiments of the present application are described in further detail.

[0036] See also Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram showing an interlocking structure, a side plate and a rear sealing plate in an embodiment of the present application is shown. Figure 2 FIG. 1 shows a schematic diagram of the assembly of an electromagnetic lock, a bracket and a side plate in an embodiment of the present application. Figure 1 For example, the first direction F1 in the present application may be the length direction of the rear sealing plate 8 , the second direction F2 may be the thickness direction of the rear sealing plate 8 , and the third direction F3 may be the width direction of the rear sealing plate 8 .

[0037] An embodiment of the present application provides an interlocking structure suitable for a removable sealing plate, including an electromagnetic lock 2 and a lock seat 1 that cooperates with the electromagnetic lock 2, wherein the electromagnetic lock 2 is installed on the side panel 7 of the switch cabinet and is fixed to the switch cabinet as a whole, and the lock seat 1 is installed on the rear sealing plate 8 of the switch cabinet and can move along with the movement of the rear sealing plate 8.

[0038] Specifically, the lock tongue 21 of the electromagnetic lock 2 includes an open position and a locked position arranged at intervals along the first direction F1, and the lock tongue 21 of the electromagnetic lock 2 is configured to be able to switch between the open position and the locked position along the first direction F1. In the embodiment of the present application, the first direction F1 refers to the extension direction of the lock tongue 21 of the electromagnetic lock 2, which is parallel to the length direction of the above-mentioned rear sealing plate 8.

[0039] When the lock tongue 21 of the electromagnetic lock 2 is switched to the open position, the lock tongue 21 is at least partially accommodated in the lock body 23 of the electromagnetic lock 2, and the end of the lock tongue 21 and the lock seat 1 are spaced apart from each other in the first direction F1, so as to remove the restriction on the movement of the lock seat 1, thereby facilitating the easy movement of the rear cover plate 8 without removing the secondary wiring, greatly improving the work efficiency, making the movement of the rear cover plate 8 more convenient and quick, and avoiding damage to the secondary wiring due to misoperation, thereby ensuring the safety and reliability of the operation.

[0040] When the lock tongue 21 of the electromagnetic lock 2 is switched to the locking position, the lock tongue 21 of the electromagnetic lock 2 can be inserted into the lock seat 1 along the first direction F1 to realize the limiting operation of the lock seat 1, and then realize the limiting operation of the rear sealing plate 8 to prevent the rear sealing plate 8 from being accidentally opened, thereby improving the operational safety of the switch cabinet.

[0041] Continue reading Figure 2 As shown, in some embodiments, the interlocking structure also includes a bracket 3 and a first fastener 4, the electromagnetic lock 2 is installed on the bracket 3, and a side wall of the bracket 3 can be fixed to the side panel 7 by means of the first fastener 4, so that the electromagnetic lock 2 is installed on the bracket 3 and fixed to the side panel 7 of the switch cabinet. It is in an immovable state, thereby eliminating the operation of removing the secondary wiring of the electromagnetic lock 2 during the opening of the rear sealing plate 8, and also avoiding the problem of the secondary wiring of the electromagnetic lock 2 being accidentally disconnected during the opening of the rear sealing plate 8, thereby improving the working efficiency and operational safety of opening the rear sealing plate 8.

[0042] Combination Figure 3 As shown, Figure 3 The figure shows a stereoscopic view of a bracket in an embodiment of the present application. The bracket 3 includes a mounting plate 31, a fixing plate 32 and at least one connecting plate 33, wherein the fixing plate 32 is mounted on the side plate 7 by means of a first fastener 4, and fits with the outer edge of the side plate 7 to achieve a stable connection with the side plate 7 by means of the first fastener 4. The mounting plate 31 is vertically connected to the fixing plate 32 and is used for mounting the electromagnetic lock 2. The larger end surface of the mounting plate 31 is parallel to the end surface of the rear sealing plate 8, thereby avoiding interference between the mounting plate 31 and the rear sealing plate 8 when the lock tongue 21 of the electromagnetic lock 2 is switched to the locking position.

[0043] See Figure 2As shown, there are two connecting plates 33, which are arranged at the top and bottom of the bracket 3, respectively, and connected between the mounting plate 31 and the fixing plate 32, so as to achieve structural support for the mounting plate 31 and the fixing plate 32. In the embodiment of the present application, the connecting plate 33 is integrally constructed into a right-angled trapezoidal plate structure, one of the right-angled sides of the connecting plate 33 is fixed to the edge of the fixing plate 32, and the other adjacent right-angled side is fixed to the edge of the mounting plate 31, so that a stable structure similar to a triangle can be formed between the mounting plate 31, the fixing plate 32 and the connecting plate 33, thereby enhancing the overall structural strength of the bracket 3.

[0044] Continue to read Figure 2 As shown, in some embodiments, the bracket 3 is provided with an adjustment hole 321, and the first fastener 4 can pass through the adjustment hole 321 along the first direction F1 and fix the bracket 3 to the side plate 7, so as to achieve a stable connection between the bracket 3 and the side plate 7. In the embodiment of the present application, the adjustment hole 321 is specifically a waist-shaped hole extending along the second direction F2, and the second direction F2 is perpendicular to the first direction F1 mentioned above, so that the operator can adjust the bracket 3 as a whole relative to the side plate 7 in the second direction F2 during the assembly process to compensate for the assembly tolerance between the bracket 3 and the side plate 7 and the rear cover plate 8.

[0045] Furthermore, a plug-in slot 11 is provided on the lock seat 1 along the first direction F1, and the plug-in slot 11 is configured as a waist-shaped slot extending along the third direction F3, and the third direction F3 is perpendicular to the first direction F1 and the second direction F2, respectively, so that even if there is a certain assembly tolerance between the lock tongue 21 of the electromagnetic lock 2 and the plug-in slot 11 of the lock seat 1, the lock tongue 21 can be smoothly inserted into the plug-in slot 11 of the lock seat 1, thereby reducing the assembly difficulty of the overall interlocking structure.

[0046] Combination Figures 1 to 3 As shown, in some embodiments, the adjustment hole 321 can be set to be multiple, and all the adjustment holes 321 are spaced apart along the third direction F3. The above-mentioned first fastener 4 can be passed through any adjustment hole 321 according to actual assembly requirements to achieve a fixed connection between the bracket 3 and the side panel 7.

[0047] In some other embodiments, a plurality of first fasteners 4 are provided, and each bracket 3 is provided with three adjustment holes 321 spaced apart along the third direction F3, and each bracket 3 is connected and fixed to the side plate 7 by means of two first fasteners 4. During actual assembly, the operator can select appropriate adjustment holes 321 according to actual assembly requirements and assembly tolerances to improve assembly accuracy.

[0048] Combination Figure 1 and Figure 4 As shown, Figure 4The assembly diagram of the lock seat and the rear sealing plate in one embodiment of the present application is shown. In some embodiments, the interlocking structure further includes a second fastener 5, and the lock seat 1 can be fixed to the rear sealing plate 8 by means of the second fastener 5 to achieve a reliable connection between the lock seat 1 and the rear sealing plate 8.

[0049] Specifically, the mounting plate 31 of the bracket 3 is provided with an avoidance hole 311 along the second direction F2. After the lock seat 1 is installed on the rear sealing plate 8, it can pass through the bracket 3 along the second direction F2 through the avoidance hole 311, so that the lock tongue 21 of the electromagnetic lock 2 can be inserted into the plug-in slot 11, thereby limiting the rear sealing plate 8 in the second direction F2. In the embodiment of the present application, the inner wall of the avoidance hole 311 is configured to be consistent with the outer edge shape of the lock seat 1.

[0050] In some other embodiments, in the first direction F1 and the second direction F2, the inner wall size of the avoidance hole 311 is larger than the outer edge size of the lock seat 1. After the lock seat 1 passes through the avoidance hole 311 along the second direction F2, a clearance gap 6 is formed between the inner wall of the avoidance hole 311 and the outer edge of the lock seat 1 to reduce the situation where the lock seat 1 is difficult to pass through the avoidance hole 311 due to assembly errors, so that the lock seat 1 can always pass through the avoidance hole 311 smoothly and be locked with the electromagnetic lock 2.

[0051] Continue reading Figure 4 As shown, in some embodiments, the electromagnetic lock 2 specifically includes a lock body 23, a lock tongue 21 and a base plate 22, wherein the lock tongue 21 is movably mounted on the lock body 23 along a first direction F1 and can be switched between a locked position and an unlocked position to achieve opening and closing control of the switch cabinet.

[0052] Specifically, the lock body 23 is fixed on the base plate 22, and the base plate 22 is fixed to the mounting plate 31 of the bracket 3 by means of the third fastener 9, so as to achieve a stable connection between the electromagnetic lock 2 and the bracket 3. In the embodiment of the present application, the base plate 22 is constructed as a rectangular plate-like structure, the lock body 23 is fixed on the base plate 22, and a clearance hole 312 for the lock body 23 to pass through is provided on the mounting plate 31 along the second direction F2, and the circumferential dimension of the clearance hole 312 is smaller than the circumferential dimension of the base plate 22, so as to achieve the limitation of the base plate 22 in the second direction F2.

[0053] In addition, an avoidance notch 81 is provided on the rear sealing plate 8 along the second direction F2 for the substrate 22 to pass through. When the lock tongue 21 is in the locked position, the electromagnetic lock 2 and the lock seat 1 cooperate with each other to limit the rear sealing plate 8. At this time, the substrate 22 can be accommodated in the avoidance notch 81 to avoid interference between the substrate 22 and the rear sealing plate 8.

[0054] In the above embodiment, the first fastener 4, the second fastener 5 and the third fastener 9 are all common fastening structures, and specifically may be locking structures such as bolts and nuts that cooperate with each other.

[0055] Continue reading Figure 1 As shown, in some embodiments, the present application further provides a switch cabinet, which includes a cabinet body and an interlocking structure suitable for a removable sealing plate as shown in any of the above embodiments. Specifically, the switch cabinet is a removable switch cabinet, and the cabinet body of the switch cabinet includes a side plate 7 and a rear sealing plate 8 arranged perpendicularly to each other, and the above interlocking structure is installed between the side plate 7 and the rear sealing plate 8 to realize the control of the opening and closing state of the switch cabinet.
