Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power system maintenance devices, specifically relating to a multi-functional simulated circuit breaker. Background Technology
[0002] Existing multi-functional simulated circuit breakers are used to realistically simulate the tripping and closing times of circuit breakers during power system system testing, thereby avoiding circuit breaker wear caused by repeated testing. Their multi-functionality is mainly reflected in their ability to simulate various operating states of the circuit breaker. In actual use, wiring is required to establish connections between the multi-functional simulated circuit breaker and the circuit breaker's terminals, resulting in numerous and complex wiring connections. The wiring method also needs to be switched when changing simulation functions. However, existing multi-functional simulated circuit breakers are usually stored in sealed boxes. Operators typically remove the simulated circuit breaker directly from the box and place it on the ground. However, most circuit breaker terminals are located in the middle of the circuit breaker enclosure. Therefore, when installing the multi-functional simulated circuit breaker or switching functions, the wiring distance is relatively long, requiring operators to repeatedly squat and stand to complete the wiring or switch wiring positions. Furthermore, since the terminals at both ends of the wiring are not within the same field of vision, wiring errors are prone to occur. To address these inconveniences, this invention proposes a multi-functional simulated circuit breaker. Utility Model Content
[0003] The purpose of this invention is to provide a multifunctional analog circuit breaker in order to solve the above-mentioned problems.
[0004] This utility model achieves the above objectives through the following technical solutions:
[0005] This utility model provides a multifunctional simulated circuit breaker, including a simulated circuit breaker body, a detachable outer bracket fitted on the simulated circuit breaker body, a hanging bracket above the outer bracket and a hanging rope for suspending the outer bracket below the hanging bracket, a wire reel box below the outer bracket, and a wire reel frame corresponding to the hanging rope and a locking component for locking the length of the hanging rope inside the wire reel box. The wire reel frame and the wire reel box are rotatably connected by a torsion spring, and a rope threading sleeve for installing the hanging rope is provided on the outer bracket.
[0006] As a further optimization of this utility model, the outer support includes a main support located on the back side of the simulated circuit breaker body, and L-shaped clamping frames are rotatably installed at both the upper and lower ends of the main support. A positioning plate is installed at the center of the main support via an adjusting screw, and the adjusting screw is rotatably connected to the positioning plate. A slot that cooperates with the positioning plate is opened on the back side of the simulated circuit breaker body.
[0007] As a further optimization of this utility model, there are four suspension ropes arranged in a rectangular array on the outside of the simulated circuit breaker body. The outer wall of the simulated circuit breaker body is provided with positioning grooves that cooperate with the suspension ropes. The rope loops correspond one-to-one with the suspension ropes and are all located on the clamping frame.
[0008] As a further optimization of this utility model, the locking assembly includes a limiting screw that is rotatably installed at the center of the wire reel box, and the bottom end of the limiting screw penetrates through the wire reel box. A screw sleeve is provided on the outer side of the limiting screw, and a number of limiting plates corresponding one-to-one with the wire reel frame are provided on the outer side of the screw sleeve. The limiting plates have an arc-shaped structure and are covered with evenly distributed protruding teeth on their sides.
[0009] As a further optimization of this utility model, a movable rod is provided on the outer side of the main support. The movable rod has a U-shaped structure and both ends are slidably sleeved with sleeves. The sleeves are rotatably connected to the main support, and a magnetic block is embedded on the side of the movable rod.
[0010] As a further optimization of this utility model, anti-slip sleeves are provided on the outer sides of both the hanger and the clamp.
[0011] The beneficial effects of this utility model are as follows:
[0012] This invention, through the cooperation of an external bracket, hanger, suspension rope, wire reel box, and locking components, achieves the effect of suspending the simulated circuit breaker body on the circuit breaker enclosure. During power system assembly testing, the simulated circuit breaker body can be suspended close to the interface, ensuring that the two terminals are within the same field of vision. When installing the simulated circuit breaker or switching its function, the operator can quickly select the connection port to be connected and perform short-distance, rapid wiring. During this process, the operator can maintain a standing posture throughout the operation without repeatedly squatting and standing, simplifying the wiring process, making it convenient and efficient. It also helps reduce the probability of wiring errors, comprehensively improving the ease of use of the simulated circuit breaker. Attached Figure Description

Detailed Implementation
[0019] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0020] Example 1
[0021] like Figure 1-5 As shown, the multifunctional simulated circuit breaker of this embodiment includes a simulated circuit breaker body 1, a detachable outer bracket fitted on the simulated circuit breaker body 1, a hanging bracket 7 above the outer bracket and a hanging rope 8 for suspending the outer bracket below the hanging bracket 7, a wire reel box 9 below the outer bracket, and a wire reel frame 10 corresponding to the hanging rope 8 and a locking component for locking the length of the hanging rope 8 inside the wire reel box 9. The wire reel frame 10 and the wire reel box 9 are rotatably connected by a torsion spring, so that the hanging rope 8 can be extended at will and automatically retracted. The outer bracket is provided with a rope threading sleeve 17 for installing the hanging rope 8.
[0022] When using this simulated circuit breaker, after opening the side cover of the circuit breaker enclosure, place the simulated circuit breaker body 1 on the ground. Then, lift the bracket 7 and lock it onto the top plate of the circuit breaker enclosure. Next, pull the simulated circuit breaker body 1 upward to a height close to the circuit breaker. Finally, adjust the length of the locking component to lock the suspension rope 8 to fix the height of the simulated circuit breaker body 1. At this point, short-distance and quick wiring can be performed between the circuit breaker's wiring port and the simulated circuit breaker body 1 as needed, making the operation convenient and efficient.
[0023] Preferably, the outer support includes a main support 2 located on the back side of the simulated circuit breaker body 1, and L-shaped clamping frames 6 are rotatably installed at both the upper and lower ends of the main support 2. A positioning plate 3 is installed at the center of the main support 2 via an adjusting screw 5, and the adjusting screw 5 is rotatably connected to the positioning plate 3. A slot 4 that cooperates with the positioning plate 3 is opened on the back side of the simulated circuit breaker body 1. The two clamping frames 6 are opened outward, and the positioning plate 3 is engaged with the slot 4. Then, the two clamping frames 6 are rotated inward to fit against the outer side of the simulated circuit breaker body 1. Then, the adjusting screw 5 is rotated to drive the entire assembly of the main support 2 and the clamping frames 6 to move towards the back side of the simulated circuit breaker body 1. The front ends of the two clamping frames 6 can then press against the front side of the simulated circuit breaker body 1, thereby fixing the outer support onto the simulated circuit breaker body 1. The outer support can be removed by reversing the operation. In scenarios where it is inconvenient to hang the simulated circuit breaker body 1, the simulated circuit breaker body 1 can be removed separately. The usage is flexible and highly adaptable.
[0024] Preferably, there are four suspension ropes 8 arranged in a rectangular array on the outside of the simulated circuit breaker body 1. The outer wall of the simulated circuit breaker body 1 is provided with positioning grooves 18 that cooperate with the suspension ropes 8. The rope sleeves 17 correspond one-to-one with the suspension ropes 8 and are all located on the clamping frame 6. The connection between the outer support and the suspension ropes 8 can be established by the cooperation of the rope sleeves 17 and the clamping frame 6, so as to realize the effect of using the outer support to carry the suspension ropes 8 and the wire reel box 9 without affecting the opening and closing of the clamping frame 6.
[0025] Preferably, the locking assembly includes a limiting screw 11 rotatably mounted at the center of the wire reel box 9, with the bottom end of the limiting screw 11 penetrating through the wire reel box 9. A screw sleeve 12 is sleeved on the outer side of the limiting screw 11, and several limiting plates 13 corresponding one-to-one with the wire reel frame 10 are provided on the outer side of the screw sleeve 12. The limiting plates 13 have an arc-shaped structure and are covered with evenly distributed protruding teeth on their sides. In the initial state, the screw sleeve 12 is located at the lowest end and does not contact the wire reel formed by the hanging rope 8 on the wire reel frame 10. Rotating the limiting screw 11 can drive the entire assembly formed by the connection of the screw sleeve 12 and the limiting plates 13 to rotate upward. The limiting plates 13 can then gradually rotate and approach the wire reel. After the limiting plates 13 press the wire reel, the protruding teeth are inserted between the wire reels, which can fix the connection between the wire reel and the wire reel frame 10, thereby locking the length of the hanging rope 8.
[0026] Preferably, the main support 2 has a movable rod 15 on its outer side. The movable rod 15 has a U-shaped structure and both ends are slidably sleeved with sleeves 14. The sleeves 14 are rotatably connected to the main support 2. A magnetic block 16 is embedded on the side of the movable rod 15. After locking the height of the simulated circuit breaker body 1, the movable rod 15 is pulled out so that the magnetic block 16 is attracted to the side wall of the circuit breaker box to fix the position of the simulated circuit breaker body 1, thereby preventing the simulated circuit breaker body 1 from shaking, improving the installation stability of the simulated circuit breaker body 1, and further improving the wiring convenience.
[0027] Preferably, both the hanger 7 and the clamp 6 are fitted with anti-slip sleeves on their outer sides.
[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
