Description

Technical Field

[0001] The present invention relates to a switch cabinet, and in particular to an interlocking structure and a switch cabinet with a one-button sequential control function. Background Art

[0002] With advancements in power equipment manufacturing, power supply devices are becoming increasingly stable. To further enhance the automation level of the power industry, various entities within the power supply industry have comprehensively implemented unmanned substation transformation. In existing switchgear, to facilitate the push-in (from the test position to the working position and locking it) and pull-out (from the working position to the test position and locking it), a chassis or trolley is typically used to carry the circuit breaker. The trolley's wheels move forward or backward along tracks within the switchgear. Existing electric chassis or trolleys include end beams, a screw rod, a motor, a handle, a vehicle body, and a control system. During operation, the screw rod drives the vehicle frame and the circuit breaker mounted on the vehicle frame to the working position or back out by shaking the handle or by driving the motor. A grounding switch is typically installed in the switchgear, and the grounding operating shaft controls the opening and closing of the grounding switch. In existing automated switchgear, a motor typically drives the grounding operating shaft to achieve closing or opening operations.

[0003] For safety reasons, when the grounding switch is closed, the chassis or trolley of the circuit breaker is not allowed to move. When the grounding switch is open, the trolley can move. After the trolley moves, the grounding switch cannot be closed. The existing safety interlock structure is usually implemented through the control circuit board, that is, only through electrical interlocking (not starting the motor), but without mechanical interlocking. Therefore, there is still a possibility of manual misoperation causing damage to components or causing casualties, or circuit failure causing malfunction of the operating shaft, causing damage to components or causing casualties.

[0031] The embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0032] Depend on Figure 1 Combine Figure 2-14 As shown, a switch cabinet includes a cabinet body, a control module and an interlocking structure with a one-button sequential control function. The interlocking structure with a one-button sequential control function includes a grounding switch 1, a vehicle body, a grounding operating shaft 2 for driving the grounding switch 1, a vehicle body operating shaft 3 for driving the vehicle body, a first driving mechanism 21 for driving the grounding operating shaft 2, and a second driving mechanism 31 for driving the vehicle body operating shaft 3. It also includes a first micro switch 22 for controlling the first driving mechanism 21, a second micro switch 32 for driving the second driving mechanism 31, a first interlocking mechanism 4 and a second interlocking mechanism 5. The first interlock mechanism 4 has a first position that interlocks the grounding operating shaft 2 and a second position that unlocks the grounding operating shaft 2 and allows free movement. The second interlock mechanism 5 has a first position that interlocks the vehicle operating shaft 3 and a second position that unlocks the vehicle operating shaft 3 and allows free movement. When the grounding operating shaft 2 operates the grounding switch 1 to close, the first interlock mechanism 4 limits the second interlock mechanism 5 so that the second interlock mechanism 5 is in the first position. When the vehicle operating shaft 3 operates the vehicle body to move, the second interlock mechanism 5 limits the first interlock mechanism 4 so that the first interlock mechanism 4 is in the first position. When the grounding operating shaft 2 operates the grounding switch 1 to open, the first interlock mechanism 4 and the second interlock mechanism 5 are both in their second positions. The first microswitch 22 and the second microswitch are both connected to a control module, which is respectively connected to the first drive mechanism 21 and the second drive mechanism 31 and is used to control the operation of the first drive mechanism 21 and the second drive mechanism 31. The beneficial effect of the present invention is that the first interlocking mechanism and the second interlocking mechanism are provided to mechanically interlock the grounding operating shaft and the vehicle body operating shaft, thereby preventing the grounding switch from malfunctioning or the vehicle body from malfunctioning, thereby avoiding damage to components and casualties. The present invention also has the advantages of simple structure, easy assembly, reliable operation, long service life, and high safety performance. The one-button sequential control function means that it can perform logical control to achieve mechanical and electrical dual interlocking. Further explanation is provided in conjunction with the accompanying drawings:

[0033] 1. Electric grounding switch interlock manual override function: During manual operation, the grounding interlock operating hole is opened (pull up the release shield and rotate it to open it. The first switching lever pops out, the first microswitch is toggled, and the switch is disconnected. Press the first valve to expose the grounding interlock operating hole). The electric grounding interlock electrical circuit (first drive mechanism) is disconnected (the electric grounding interlock controller can perform logical judgment to achieve electrical interlocking), making the electric grounding switch inoperable. This provides manual override for the electric grounding interlock first drive mechanism.

[0034] 2. The electric propulsion mechanism is interlocked with the electric earthing switch;

[0035] 2.1 The electric propulsion mechanism drives the circuit breaker (chassis or trolley) to the test position. The earthing switch can be opened and closed. The earthing switch can be closed manually or by the first driving mechanism;

[0036] 2.11 The first drive mechanism (which may be a motor) drives the grounding operating shaft to rotate and control the grounding switch to close. At this time, the grounding operating shaft drives the crank arm to rotate, which drives the first valve downward. The first interlock plate or the first movable plate switches the second microswitch via the second switching lever (in the present invention, the second microswitch is switched by the bent portion of the first interlock plate. Of course, in actual production, the second microswitch can also be directly driven to switch by the first valve). The second microswitch switches to control the disconnection of the second drive mechanism (logical judgment can be performed by the electric propulsion mechanism controller to achieve electrical interlocking), making the electric propulsion mechanism (second drive mechanism) inoperable, thus achieving electrical interlocking.

[0037] 2.12 When the earthing switch is closed, the first interlock plate is simultaneously operated to move downward. At this time, the first baffle presses the second interlock plate to move it toward the inside of the end beam. At this time, the interlock rod is originally in the first clearance groove position of the second interlock plate. Since the movement of the second interlock plate is in the first limit groove position (the first limit groove can be a straight groove, the first clearance groove position can be circular, and the interlock rod is flat, it can rotate in the first clearance groove and be limited by the first limit groove). At this time, the driving block of the first baffle is set in the straight groove, and the second interlock plate cannot be extended to reset, and is reliably interlocked. At this time, the vehicle body operating shaft is limited and cannot be manually operated, achieving mechanical locking;

[0038] 2.2 The grounding switch is open. At this point, the grounding switch can be closed or the circuit breaker (chassis or trolley) can be moved from the test position to the operating position. When the grounding switch is open, the crank arm no longer presses the limiter on the first valve. The second interlock plate pushes the first stopper, thereby moving the first interlock plate upward (of course, the first interlock plate and first valve can also be reset by a spring or tension spring). The second interlock plate automatically pops out (extending toward the outside of the end beam, which can be achieved by a spring or tension spring (not shown in the figure)). The interlock rod is in the first clearance groove of the second interlock plate. At this time, the second drive mechanism (or trolley) can be electrically (remotely) operated, or the second valve can be pressed to manually operate the vehicle body operating shaft. After the trolley or chassis leaves the test position, the stop pin pressed by the trolley or chassis pops out, and its limit block is set in the second limit groove. The second interlock plate cannot be pressed back, and the first interlock plate is interlocked by the second interlock plate. This allows the trolley or chassis to operate and the grounding switch cannot be closed, ensuring product safety.

[0039] The first interlocking mechanism 4 includes a first interlocking plate 41 and a first baffle 42, and the second interlocking mechanism 5 includes a second interlocking plate 51. The first baffle 42 has a first state in which it is pressed and limited by the second interlocking plate 51 when the first interlocking mechanism 4 is in the first position, and a second state in which it presses the second interlocking plate 51 when the second interlocking mechanism 5 is in the first position. The first interlocking plate and the second interlocking plate interlock the first and second interlocking mechanisms, thereby achieving mechanical interlocking and preventing accidental operation of the ground operating shaft or the vehicle body operating shaft.

[0040] The present invention also includes a base plate 43, a first valve 44, and a shielding plate 45. The shielding plate 45 blocks the first valve 44 and abuts against the first microswitch 22 via a first switching lever 46, thereby switching the first microswitch 22. The shielding plate 45 is hinged to the base plate 43 via a pin 47, which passes through the base plate 43 and slidably engages with the base plate 43. The shielding plate 45 is provided with a shielding portion 451 for blocking the first switching lever 46, a locking portion 452 for engaging with the base plate 43, and a padlock hole 453 for receiving a padlock. Specifically, the first valve 44 is linked to the first interlocking plate 41. The first interlocking plate 41 is provided with a second switching lever 48 for switching the second microswitch 32. The grounding operating shaft 2 is provided with a crank arm 23, and the first valve 44 is provided with a limiter 441 for limiting the rotation of the grounding operating shaft 2. The setting of the shielding plate and the first valve avoids misoperation of the grounding operating shaft, making the product safer and protecting the grounding operating shaft at the same time.

[0041] The first interlocking plate 41 is provided with an interlocking frame 49 at the first baffle 42. The first interlocking plate 41 vertically slides with the interlocking frame 49. The first baffle 42 passes through the interlocking frame 49 and slides horizontally with the interlocking frame 49. The first interlocking plate 41 is provided with a linear groove 411 and an oblique groove 412. The first baffle 42 is provided with a driving block, which is disposed in the linear groove 411 or the oblique groove 412. This structure ensures smooth and reliable movement of the first baffle. Specifically, the first baffle is in an inverted "L" shape. The vertical portion is provided on the interlocking frame and slides with the interlocking frame to serve as a guide and limiter. The bent portion facilitates pressing of the first interlocking portion. The structure is simple, and the driving block is provided on the vertical portion.

[0042] The present invention also includes an end beam 52 and an interlocking rod 53. The second interlocking plate 51 is provided with a first clearance groove 511 for free rotation of the interlocking rod 53 and a first limiting groove 512 for limiting the rotation of the interlocking rod 53. When the grounding operating shaft 2 operates the grounding switch 1 to close, the second interlocking plate 51 interlocks the vehicle operating shaft 3 via the limiting interlocking rod 53. The interlocking rod of the present invention can be interlocked when the second interlocking plate retracts, achieving a mechanical interlock to prevent accidental operation of the vehicle operating shaft.

[0043] The end beam 52 is provided with a handle frame 54 and a second valve 55. The interlocking lever 53 is provided with a rotating arm 531. The second valve 55 is provided with a drive hole 551 for facilitating operation of the rotating arm 531. The rotating arm 531 is inserted into the drive hole 551 and is interlocked with the second valve 55. The second valve 55 has a first position for blocking the vehicle body operating shaft 3 and a second position for driving the interlocking lever 53 to rotate when the vehicle body operating shaft 3 is opened. Rotation of the second valve drives the rotating arm and the interlocking lever to rotate, thereby interlocking the second valve by limiting the rotation of the interlocking lever, thereby preventing accidental operation of the second valve opening and operating the vehicle body operating shaft.

[0044] The end beam 52 is provided with a stop pin 56, which passes through the second interlock plate 51. The second interlock plate 51 is provided with a sliding groove 513 and a second limiting groove 514. The stop pin 56 is provided with a limiting block 57. When the vehicle operating shaft 3 is actuated, the limiting block 57 is driven by an elastic member 58 to be positioned within the second limiting groove 514 to interlock the second interlock plate 51. When the stop pin is limited by the vehicle body (test position), the stop pin retracts, allowing the second interlock plate to move freely. When the grounding switch is opened and the vehicle body leaves the test position, the stop pin pops out under the action of the elastic member, and the limiting block is located in the second limiting groove. At this time, the second interlock plate retracts and is limited, that is, the second interlock plate abuts the first baffle. The first baffle limits the first interlock plate via the driving block, and the grounding operating shaft cannot operate the grounding switch to close, achieving reliable interlocking and high product safety performance.
