Description

Technical Field

[0001] This application relates to the field of pole-mounted circuit breaker technology, and in particular to a pole-mounted circuit breaker test bench. Background Technology

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range. The boundary between high and low voltage is somewhat blurred; generally, those above 3kV are considered high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. When serious overloads, short circuits, or undervoltage faults occur, they can automatically disconnect the circuit. Their function is equivalent to a combination of a fuse switch and over / under-temperature relays. Moreover, generally, no parts need to be replaced after interrupting a fault current.

[0003] In existing circuit breaker test benches, the testing equipment is often placed inside the test bench, which is inconvenient to remove during use. Furthermore, when multiple devices are placed inside the test bench, the internal space utilization needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a pole-mounted circuit breaker test bench, which overcomes the deficiencies of existing technologies. It aims to solve the problems in existing circuit breaker test benches where testing equipment is often placed inside the test bench, making it inconvenient to remove during use, and where the internal space utilization needs to be improved when multiple devices are placed inside the test bench.

[0005] To achieve the above objectives, this application provides the following technical solution: a pole-mounted circuit breaker test bench, comprising a support frame, wherein two sets of fixing mechanisms and a testing device are arranged inside the support frame, the two sets of fixing mechanisms are symmetrically arranged, each fixing mechanism including a connecting rod and a bottom rod, the bottom rod being fixedly connected to the support frame, the connecting rod being located at the top of the bottom rod, and a moving groove and a limiting groove being respectively opened on one side of the connecting rod and the bottom rod, and multiple sets of support rods are arranged between the two sets of fixing mechanisms, each set of support rods having a moving block on both sides, both sets of moving blocks being slidably connected inside the moving groove, two sets of connecting mechanisms being arranged at the bottom of the support rods, each connecting mechanism including a fixing plate, the fixing plate being fixedly connected to the support rods, a fixing spring being arranged on one side of the fixing plate, an extension plate being arranged at the other end of the fixing spring, a fixing slider being arranged on one side of the extension plate, the fixing slider being slidably connected inside the limiting groove, a placement mechanism being slidably connected above the multiple sets of support rods, and the testing device being located above the placement mechanism.

[0006] By adopting the above technical solution and setting a fixing mechanism, the support rod can be fixed during use. After the testing equipment is placed on top of the placement mechanism, it can be directly pulled out from the inside of the support frame by sliding the placement mechanism. The two sets of connecting mechanisms at the bottom have an extension plate on one side that abuts against the outside of the bottom rod under the force of the fixing spring. At the same time, the fixing slider is slidably connected to the inside of the limiting groove, which can ensure a tight connection between the fixing mechanism and the support rod. When it is necessary to disassemble and replace the support rod, the support rod can be separated from the bottom rod by moving the extension plate. This makes the use more flexible and allows the support rod and placement mechanism to be replaced according to the size of the equipment. At the same time, the internal testing equipment can be quickly pulled out from the inside of the support frame during use, which is more convenient and can effectively improve the utilization rate of the internal space of the support frame and enhance the practicality of the device.

[0008] By adopting the above technical solution and setting up a placement mechanism, when the testing equipment is placed on top of the placement mechanism, the side clamps on both sides will clamp the testing equipment under the drive of the clamping springs, ensuring that the testing equipment will not shift inside the support frame, making it more convenient to use and improving the practicality of the device.

[0009] As a preferred technical solution of this application, each of the two sets of side clamps is provided with a sliding member at one end, and a limiting slide plate is slidably connected between the sliding member and the side clamp.

[0010] By adopting the above technical solution and setting limiting slides, the limiting slides on both sides can limit the detection equipment during use, which can fix the detection equipment on the top of the placement mechanism and improve the practicality of the device.

[0011] As a preferred technical solution of this application, a limiting plate is provided on the top of the bearing plate, and the limiting plate is located on one side of the two sets of side clamps.

[0012] By adopting the above technical solution and setting a limiting plate, it can cooperate with the limiting slide plate during use, which can further improve the limiting effect on the detection equipment and enhance the practicality of the device.

[0013] As a preferred technical solution of this application, the top of the support rod is provided with a top sliding groove, and the bottom of the bearing plate is provided with a movable roller, which is slidably connected to the inside of the top sliding groove.

[0015] As a preferred technical solution of this application, the bottom of the movable block is provided with a bottom stabilizing groove, and the top of the extension plate is provided with a stabilizing slider, which is slidably connected to the inside of the bottom stabilizing groove.

[0016] By adopting the above technical solution and setting a bottom stabilizing groove, the stability of the extension plate during movement can be improved, thus enhancing the practicality of the device.

[0017] As a preferred technical solution of this application, the front of the support frame is provided with two sets of front baffles, and both sets of front baffles are hinged to the support frame.

[0018] By adopting the above technical solution, the front baffle can shield the interior of the support frame, protect the internal equipment, and improve the practicality of the device.

[0019] As a preferred technical solution of this application, the interior of the two sets of front baffles is provided with an observation window, and the front of the two sets of front baffles is provided with a handle.

[0020] By adopting the above technical solution, the observation window makes it more convenient to open the front panel, and the handle allows for observation of the internal condition of the support frame from the outside, thus improving the practicality of the device.

[0021] The beneficial effects of this application are:

[0022] 1. By setting up a fixing mechanism, the support rod can be fixed during use. After placing the testing equipment on top of the placement mechanism, the testing equipment can be directly pulled out from the inside of the support frame by sliding the placement mechanism. The two sets of connecting mechanisms at the bottom have an extension plate on one side that abuts against the outside of the bottom rod under the force of the fixing spring. At the same time, the fixing slider is slidably connected to the inside of the limiting groove, which can ensure a tight connection between the fixing mechanism and the support rod. When it is necessary to disassemble and replace the support rod, the support rod can be separated from the bottom rod by moving the extension plate. This makes the use more flexible. The support rod and placement mechanism can be replaced according to the size of the equipment. At the same time, the internal testing equipment can be quickly pulled out from the inside of the support frame during use, which is more convenient and can effectively improve the utilization rate of the internal space of the support frame and enhance the practicality of the device.

[0030] Reference Figure 1-4 A pole-mounted circuit breaker test bench includes a support frame 1. Inside the support frame 1 are two sets of fixing mechanisms 3 and a testing device 2. The two sets of fixing mechanisms 3 are symmetrically arranged. Each fixing mechanism 3 includes a connecting rod 301 and a bottom rod 302.

Multiple sets of support rods 4 are arranged between the two sets of fixing mechanisms 3. Moving blocks 401 are provided on both sides of each set of support rods 4. All moving blocks 401 are slidably connected to the inside of the moving groove 303. Two sets of connecting mechanisms 5 are provided at the bottom of the support rod 4. Each connecting mechanism 5 includes a fixed plate 501, which is fixedly connected to the support rod 4.

A sliding member 606 is provided at one end of each of the two sets of side clamps 603, and a limiting slide plate 607 is slidably connected between the sliding member 606 and the side clamps 603.

[0031] By setting the fixing mechanism 3, the support rod 4 can be fixed during use. After the detection device 2 is placed on top of the placement mechanism 6, the detection device 2 can be directly pulled out from the inside of the support frame 1 by sliding the placement mechanism 6. The two sets of connecting mechanisms 5 at the bottom have an extension plate 503 on one side that abuts against the outside of the bottom rod 302 under the force of the fixing spring 502. At the same time, the fixing slider 504 is slidably connected to the inside of the limiting groove 304, which can ensure a tight connection between the fixing mechanism 3 and the support rod 4. When it is necessary to disassemble and replace the support rod 4, the support rod 4 can be separated from the bottom rod 302 by moving the extension plate 503. This makes the use more flexible and allows the support rod 4 and placement mechanism 6 to be replaced according to the size of the equipment. At the same time, the detection device 2 can be quickly pulled out from the inside of the support frame 1 during use, which is more convenient and can effectively improve the utilization rate of the internal space of the support frame 1 and enhance the practicality of the device. By setting the limiting slide plate 607, the limiting slide plates 607 on both sides can limit the detection device 2 during use, which can fix the detection device 2 on the top of the placement mechanism 6 and improve the practicality of the device.

[0032] Reference Figure 1-4 The placement mechanism 6 includes a support plate 601, with four sets of mounting slots 602 on the top of the support plate 601. Clamping springs 604 are installed inside the mounting slots 602.

A limiting plate 605 is provided at the top of the support plate 601, located on one side of each set of side clamping plates 603. A bottom stabilizing groove 403 is provided at the bottom of the moving block 401, and a stabilizing slider 505 is provided at the top of the extension plate 503, slidably connected inside the bottom stabilizing groove 403. By setting up the placement mechanism 6, when the detection device 2 is placed on top of the placement mechanism 6, the side clamps 603 on both sides will clamp the detection device 2 under the drive of the clamping springs 604, ensuring that the detection device 2 will not shift inside the support frame 1, making it more convenient to use and improving the practicality of the device; by setting up the limiting plate 605, it can cooperate with the limiting slide plate 607 during use, which can further improve the limiting effect on the detection device 2 and improve the practicality of the device; by setting up the bottom stabilizing groove 403, the stability of the extension plate 503 during movement can be improved during use, improving the practicality of the device.

[0033] Reference Figure 1-4The top of the support rod 4 is provided with a top sliding groove 402, and the bottom of the bearing plate 601 is provided with a movable roller 7, which is slidably connected to the inside of the top sliding groove 402. By providing the movable roller 7, it is possible to ensure that the placement mechanism 6 can be moved more conveniently and stably outside the support rod 4 during use, and that it is easier to pull out, thus improving the practicality of the device. The front of the support frame 1 is provided with two sets of front baffles 101, and both sets of front baffles 101 are hinged to each other. The front baffles 101 can cover the inside of the support frame 1, protecting the internal equipment and improving the practicality of the device. The two sets of front baffles 101 are provided with observation windows 102 inside, and each set of front baffles 101 is provided with a handle 103 on the front. The observation windows 102 make it easier to open the front baffles 101, and the handles 103 allow observation of the inside of the support frame 1 from the outside, thus improving the practicality of the device.

[0034] Working principle: By setting the fixing mechanism 3, the support rod 4 can be fixed during use. After the detection device 2 is placed on top of the placement mechanism 6, the detection device 2 can be directly pulled out from the inside of the support frame 1 by sliding the placement mechanism 6. The two sets of connecting mechanisms 5 at the bottom have an extension plate 503 on one side that abuts against the outside of the bottom rod 302 under the force of the fixing spring 502. At the same time, the fixing slider 504 is slidably connected to the inside of the limiting groove 304, which can ensure a tight connection between the fixing mechanism 3 and the support rod 4. When it is necessary to disassemble and replace the support rod 4, the support rod 4 can be moved to the bottom rod 302 by moving the extension plate 503. The separation between the support rod 4 and the placement mechanism 6 allows for greater flexibility during use. The support rod 4 and the placement mechanism 6 can be replaced according to the size of the equipment. At the same time, the internal detection device 2 can be quickly pulled out from the inside of the support frame 1 during use, which is more convenient and can effectively improve the utilization rate of the internal space of the support frame 1 and enhance the practicality of the device. By setting the placement mechanism 6, when the detection device 2 is placed on the top of the placement mechanism 6, the side clamps 603 on both sides will clamp the detection device 2 under the drive of the clamping springs 604, ensuring that the detection device 2 will not shift inside the support frame 1, which is more convenient during use and enhances the practicality of the device.

[0035] Among them, by setting the limiting slide plate 607, the limiting slide plates 607 on both sides can limit the detection device 2 during use, and can fix the detection device 2 on the top of the placement mechanism 6, thereby improving the practicality of the device. By setting the limiting plate 605, it can cooperate with the limiting slide plate 607 during use, thereby further improving the limiting effect on the detection device 2 and improving the practicality of the device.

[0036] Meanwhile, by setting the movable rollers 7, it can be ensured that the placement mechanism 6 moves more conveniently and stably outside the support rod 4 during use, and that it is easier to pull out, thus improving the practicality of the device.

[0037] In addition, by setting the bottom stabilizing groove 403, the stability of the extension plate 503 during movement can be improved, thus enhancing the practicality of the device; the front baffle 101 can shield the interior of the support frame 1, protecting the internal equipment and enhancing the practicality of the device; the observation window 102 makes it easier to open the front baffle 101, and the handle 103 allows observation of the interior of the support frame 1 from the outside, further enhancing the practicality of the device.
