Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and in particular to an electrical cabinet interlocking mechanism. Background Technology

[0002] Traditional interlocking mechanisms include an isolating operating shaft and an interlocking rod that is linked to the isolating operating shaft. The interlocking rod moves when the isolating operating shaft rotates, but during reset, it is reset by a spring fitted on the interlocking rod. However, when installing the spring, it is necessary to first install the spring between the plates and then install the interlocking rod. The installation requires the spring to be fixed manually, which is time-consuming and labor-intensive. Summary of the Invention

[0003] The purpose of this utility model is to provide an interlocking mechanism for electrical cabinets to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An interlocking mechanism for an electrical cabinet is characterized by comprising a frame, an isolating operating shaft, and a grounding operating shaft. The isolating operating shaft and the grounding operating shaft are rotatably mounted on one side of the frame. A circuit breaker interlocking rod and a lower door interlocking rod are linked to the isolating operating shaft. Pressure plates are connected to the upper ends of the circuit breaker interlocking rod and the lower door interlocking rod. An interlocking frame is provided between the frames. Both the circuit breaker interlocking rod and the lower door interlocking rod include an upper rod portion, a connecting spring, and a lower rod portion. The two ends of the connecting spring are welded to the upper rod portion and the lower rod portion, respectively. A through groove is provided in the lower rod portion for the first opening / closing indicator rod to pass through.

[0006] The present invention further includes a grounding operation shaft with a grounding switch interlocking rod, and the grounding switch interlocking rod is linked to a second opening / closing indicator rod. The grounding switch interlocking rod has the same structure as the circuit breaker interlocking rod and the lower door interlocking rod.

[0007] The present invention is further provided that the first opening and closing indicator rod and the second opening and closing indicator rod are connected to an indicator plate, and the indicator plate is located on the outside of the mechanism frame.

[0008] The present invention further provides that the isolation operating shaft and the grounding operating shaft are provided with a recessed notch at one end of the mechanism frame, and a limit block is formed in the corresponding circular hole on the mechanism frame. During the rotation of the isolation operating shaft and the grounding operating shaft, the limit block contacts or separates from the first side and the second side of the notch, thereby controlling the rotation angle of the isolation operating shaft and the grounding operating shaft.

[0009] The beneficial effects of this utility model are as follows: In the structure of the circuit breaker interlocking rod and the lower door interlocking rod of this utility model, the resetting connecting spring is set between the upper rod and the lower rod, which facilitates the installation of the circuit breaker interlocking rod and the lower door interlocking rod.

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figure 1-3As shown, this utility model is an interlocking mechanism for an electrical cabinet, including a frame 100, an isolation operating shaft 200, and a grounding operating shaft 300. The isolation operating shaft 200 and the grounding operating shaft 300 are rotatably mounted on one side of the frame 100. The isolation operating shaft 200 is linked to a circuit breaker interlocking rod 210 and a lower door interlocking rod 220. The upper ends of the circuit breaker interlocking rod 210 and the lower door interlocking rod 220 are connected to pressure plates 230. An interlocking frame 400 is provided between the frames 100. The circuit breaker interlocking rod 210 and the lower door interlocking rod 220 each include an upper rod part 211, a connecting spring 212, and a lower rod part 213. The two ends of the connecting spring 212 are welded to the upper rod part 211 and the lower rod part 213, respectively. The lower rod part 213 has a through groove 214 through which the first opening / closing indicator rod 500 passes. By setting the circuit breaker interlocking rod 210 and the lower door interlocking rod 220, only single operation is allowed during switching operations, preventing interlocking and effectively reducing the possibility of misoperation, thus ensuring a high safety factor. The circuit breaker interlocking rod 210 and the lower door interlocking rod 220 incorporate a reset spring between the upper and lower rod sections, facilitating their installation.

[0019] In this invention, the grounding operating shaft 300 is linked to a grounding switch interlocking rod 310, which is linked to a second opening / closing indicator rod 320. The grounding switch interlocking rod 310 has the same structure as the circuit breaker interlocking rod 210 and the lower door interlocking rod 220. This structure is designed to display the opening / closing status of the grounding switch interlocking rod 310 via the second opening / closing indicator rod 320, facilitating observation. In this invention, the first opening / closing indicator rod 500 and the second opening / closing indicator rod 320 are connected to an indicator plate 600, which is located on the outside of the frame 100. This structure displays the opening / closing status to the operator via the indicator plate 600, providing a simple and intuitive view.

[0020] In this invention, the isolation operating shaft 200 and the grounding operating shaft 300 are provided at one end of the mechanism frame 100, each with a recessed notch 700. Correspondingly, a limiting block 800 is formed within a circular hole on the mechanism frame 100. During rotation, the limiting block 800 contacts or separates from the first and second sides of the notch 700. This structure, through the cooperation of the limiting block 800 and the notch 700, limits the rotation angle of the isolation operating shaft 200 and the grounding operating shaft 300, ensuring accurate rotation and thus guaranteeing operational accuracy. The method of using this utility model is as follows: When the staff needs to separate the high and low voltage chambers, firstly rotate the isolation operating shaft 200 to drive the circuit breaker interlocking rod 210 and the lower door interlocking rod 220 to rotate synchronously. At this time, the upper rod part 211 of the upper circuit breaker interlocking rod 210 leaves the top of the circuit breaker handle, and at the same time, the upper rod part 211 of the lower door interlocking rod 220 leaves the top of the lower door handle. Then, open the lower door and pull it open to a certain distance, and manually rotate or close the lower door of the high voltage chamber. Then, rotate the grounding operating shaft 300 to drive the rotation of the grounding switch interlocking rod 310, so that the upper rod part of the grounding switch interlocking rod 310 leaves the top of the grounding switch handle. At this time, the grounding switch can be pulled out. Finally, after rotating the isolation operating shaft 200 to its original position, push the lower door of the high and low voltage chamber into the closed position, and turn on the electric motor of the high voltage chamber into the closed position by rotating the grounding operating shaft 300 clockwise. The above method optimizes the steps for safely unlocking and separating the high and low voltage chambers, reducing the possibility of human error. Furthermore, the equipment allows for locking and unlocking of the electrical cabinet without additional manpower, and the corresponding opening and closing indicators can be checked by rotating the isolation operating shaft 200 and the grounding operating shaft 300, saving time and effort.
