Abstract
Description
Technical Field
[0001] This application relates to the field of electrical equipment technology, and more specifically to an interlocking device for electrical cabinet cell compartments. Background Technology
[0002] Currently, in existing electrical system technologies, there is no mechanical interlock between the electrical cabinet cell compartment and the circuit breaker. Regardless of whether the electrical cabinet is open or closed, the circuit breaker can be manually switched between different positions by driving the drive mechanism of the electrical cabinet cell compartment. When the circuit breaker is in the closed state, misoperation will occur, causing phase-to-phase short circuits and other serious accidents such as personal injury. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, the purpose of this application is to provide an interlocking device for electrical cabinet cell compartments, thereby effectively solving the above-mentioned technical problems.
[0004] To achieve the above objectives, this application adopts the following technical solution: This application provides an interlocking device for an electrical cabinet cell, comprising: breaker, Linkage rod, the first end of which is inserted into the inner cavity of the circuit breaker. A knob is connected to the second end of the connecting rod. Rotating the knob causes the connecting rod to rotate, thereby switching the circuit breaker between open and closed states. An interlocking structure is provided, which is connected to the connecting rod. The interlocking structure can lock the connecting rod when the circuit breaker is closed, so that the knob cannot drive the connecting rod to rotate.
[0005] Furthermore, the interlocking structure includes a limiting plate and a locking pin, wherein, The limiting plate is fixedly sleeved on the connecting rod and rotates synchronously with the connecting rod. The limiting plate has a locking groove that extends to one edge of the limiting plate. The locking pin is movably disposed on one side of the limiting plate, and the locking pin can be inserted into the locking groove so that the locking pin limiting plate prevents the connecting rod from rotating.
[0006] Furthermore, the interlocking structure also includes a telescopic drive device, which is disposed on one side of the limiting plate and is connected to the locking pin to drive the locking pin to extend or retract.
[0007] Furthermore, the limiting plate includes a circular disc-shaped limiting plate with a rectangular hole at its center. The connecting rod has a rectangular cross-section and passes through the rectangular hole to fix the limiting plate onto the connecting rod.
[0008] Furthermore, a mounting base is provided at the second end of the connecting rod, and the knob is rotatably mounted on the mounting base, which is provided with a circuit breaker position indicator.
[0009] Beneficial effects This application provides an interlocking device for electrical cabinet cell compartments. By setting an interlocking structure to lock the connecting rod, the electrical cabinet cell compartment cannot be opened by turning the knob when the circuit breaker is closed. The interlocking structure must be used to unlock the connecting rod to open the compartment. This effectively solves the problem of misoperation and improves personnel safety.

[0016] Example One embodiment of this application provides an interlocking device for electrical cabinet cell compartments, such as... Figure 1 As shown, the device includes a circuit breaker 1, which is a device for opening and closing the electrical cabinet cell compartment. When the circuit breaker 1 is closed, the electrical cabinet cell compartment is closed; when the circuit breaker 1 is opened, the electrical cabinet cell compartment is opened. Link 2, the first end of the interlocking link 2 is inserted into the inner cavity of the circuit breaker 1, and the circuit breaker 1 can be switched between open and closed states by rotating the link 2; Knob 3 is connected to the second end of connecting rod 2. Rotating knob 3 can drive connecting rod 2 to rotate so that circuit breaker 1 can switch between open and closed states. The second end of connecting rod 2 is provided with mounting base 4. Knob 3 is rotatably mounted on mounting base 4. The mounting base 4 is provided with circuit breaker 1 position marking. The interlocking structure is connected to the connecting rod 2. When the circuit breaker 1 is closed, the interlocking structure can lock the connecting rod 2 to prevent the knob 3 from rotating the connecting rod 2. The interlocking structure includes a limiting plate 5 and a locking pin 6. The limiting plate 5 is fixedly sleeved on the connecting rod 2 and rotates synchronously with the connecting rod 2. A locking groove 7 is provided on the limiting plate 5, extending to one edge of the limiting plate 5. The locking pin 6 is movably disposed on one side of the limiting plate 5 and can be inserted into the locking groove 7 to limit the connecting rod 2 from rotating. The interlocking structure also includes a telescopic drive device 8. A telescopic drive device 8 is connected to a locking pin 6 and positioned on one side of the limiting plate 5 to drive the locking pin 6 to extend or retract. The limiting plate 5 includes a circular disc-shaped limiting plate 5 with a rectangular hole in the center. The connecting rod 2 has a rectangular cross-section and passes through the rectangular hole to fix the limiting plate 5 onto the connecting rod 2. In this embodiment, the connecting rod 2 is locked by setting an interlocking structure. When the circuit breaker 1 is closed, the electrical cabinet cell cannot be opened by turning the knob 3. The interlocking structure is required to unlock the connecting rod 2 to open it, which effectively solves the problem of misoperation and improves personnel safety.
