Description

Technical Field

[0001] This utility model relates to the field of pulse current monitoring technology, specifically to an intelligent pulse current monitoring device for switchgear. Background Technology

[0002] A switchgear is an electrical device. External power lines first enter the main control switch inside the cabinet, then proceed to the branch control switches, with each branch circuit configured according to its needs. The main function of a switchgear is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes of a power system. The main components inside a switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices.

[0003] However, the installation and disassembly of switchgear monitoring devices based on ultra-high frequency and pulse current are very troublesome. Therefore, we propose a switchgear monitoring device based on ultra-high frequency and pulse current.

[0004] As disclosed in Chinese Patent CN214124463U, the switch cabinet monitoring device based on ultra-high frequency and pulse current has an overall structure in which the right side of the connecting plate is used to connect the various devices of the monitoring device. When disassembling, the fixing screw is manually turned to disengage it from the threaded groove on the back side of the inner cavity of the device housing, and then the connecting plate can be removed. This makes it easy to disassemble and install the connecting plate.

[0005] However, the components in the monitoring device are of different sizes, while the spacing between the connecting plates inside the monitoring device is the same and cannot be adjusted. If there are components that are too long in the monitoring device, they cannot be installed inside the monitoring device. Installing smaller components on the connecting plates would waste the space between the connecting plates.

[0006] Therefore, we urgently need to provide a switchgear pulse current intelligent monitoring device that facilitates adjustment of installation space. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent monitoring device for pulse current in switchgear, in order to solve the problem mentioned in the background art that the spacing of the connecting plates inside the monitoring device is the same and cannot be adjusted.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a switch cabinet pulse current intelligent monitoring device, including a device housing and a cover for installing components of the switch cabinet pulse current intelligent monitoring device, the cover being bolted to the front end of the device housing, an installation mechanism being connected inside the device housing, and a wire harness mechanism being connected to the bottom inner side of the device housing.

[0009] The mounting mechanism includes a mounting plate disposed inside the device housing. An upper sliding plate is welded to the upper middle position of the mounting plate, and a lower sliding plate is welded to the lower middle position of the mounting plate. A horizontal limiting rod is fixedly connected to the upper inner side of the device housing, and a horizontal threaded rod is fixedly connected to the lower inner side of the device housing. An adjusting ring is connected to the outer end of the threaded rod.

[0010] A further improvement is that the mounting plate has threaded holes spaced at equal intervals inside. By passing the bolt through the component to be installed and then threading it into the threaded holes inside the mounting plate, the component used for intelligent monitoring of pulse current in the switch cabinet can be installed on the mounting plate.

[0011] A further improvement is that the upper and lower sliding plates are provided with sliding holes inside. The sliding hole inside the upper sliding plate is slidably connected to the outer side of the limiting rod, and the sliding hole inside the lower sliding plate is slidably connected to the outer side of the threaded rod. Thus, when the mounting plate moves, the upper and lower sliding plates at its upper and lower ends will slide along the outer side of the limiting rod and the threaded rod.

[0012] A further improvement is that the inner side of the adjusting ring is provided with an internal thread, the outer side of the threaded rod is connected to the inner side of the adjusting ring with a thread, and the outer side of the adjusting ring abuts against the left and right sides of the lower sliding plate. Thus, after moving each mounting plate inside the device housing, the adjusting ring is rotated to move it to the left and right sides of the lower sliding plate, and then each lower sliding plate can be fixed between the adjusting rings.

[0013] A further improvement is that the wire harness mechanism includes a base plate fixedly connected to the bottom of the inner side of the device housing. Round rods are fixedly connected at equal intervals to the upper front end of the base plate. A top plate is welded to the upper end of the round rods. A spring is fixedly connected to the lower side of the top plate. A movable plate is fixedly connected to the lower end of the spring. A U-shaped plate is fixedly connected to the rear end of the movable plate.

[0014] A further improvement is that a circular hole is provided in the middle of the moving plate, and the outer side of the circular rod is slidably connected to the inner side of the circular hole, so that when the spring bounces, the moving plate can be driven to slide along the outer side of the circular rod.

[0015] A further improvement is that the lower side of the U-shaped plate abuts against the upper side of the base plate, thereby placing the wires at the outer ends of each component on the lower end of the U-shaped plate above the base plate, confining the wires within the U-shaped plate, thus neatly constraining the wires inside the device housing within the U-shaped plate.

[0016] In summary, this application discloses an intelligent monitoring device for pulse current in switchgear.

[0017] In this technical solution, after moving each mounting plate inside the device housing, the adjusting ring is rotated to move it to the left and right sides of the lower sliding plate. Then, each lower sliding plate can be fixed between the adjusting rings. This allows the position of each mounting plate inside the device housing to be adjusted and then re-fixed, so that the spacing between each mounting plate can be adjusted to a suitable installation spacing according to the length of the component to be installed before installation.

[0018] Furthermore, when installing components onto the outer end of the mounting plate, first pull up the U-shaped plate, then place the wires at the outer ends of each component on the lower end of the U-shaped plate above the base plate. Next, release the U-shaped plate, and the spring will push the moving plate downward, causing the U-shaped plate to move down to the upper side of the contact base plate. This will confine the wires within the U-shaped plate, thus neatly constraining the wires inside the device housing within the U-shaped plate. This facilitates the disassembly and repair of components inside the device housing when the monitoring device is damaged. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4The present invention provides a technical solution: a switch cabinet pulse current intelligent monitoring device, including a device housing 1 and a cover 2 for installing components of the switch cabinet pulse current intelligent monitoring device. The cover 2 is installed to the front end of the device housing 1 by bolts. An installation mechanism is connected inside the device housing 1, and a wire harness mechanism is connected to the bottom inner side of the device housing 1.

[0026] The mounting mechanism includes a mounting plate 301 disposed inside the device housing 1. The mounting plate 301 has threaded holes evenly spaced inside. By passing bolts through the components to be installed and then threading them into the threaded holes inside the mounting plate 301, the components used for intelligent monitoring of pulse current in the switch cabinet can be installed onto the mounting plate 301.

[0027] An upper sliding plate 302 is welded to the middle of the upper side of the mounting plate 301, and a lower sliding plate 303 is welded to the middle of the lower side of the mounting plate 301. A horizontal limiting rod 304 is fixedly connected to the upper inner side of the device housing 1, and a horizontal threaded rod 305 is fixedly connected to the lower inner side of the device housing 1. Sliding holes are opened inside the upper sliding plate 302 and the lower sliding plate 303. The sliding hole inside the upper sliding plate 302 is slidably connected to the outer side of the limiting rod 304, and the sliding hole inside the lower sliding plate 303 is slidably connected to the outer side of the threaded rod 305. Thus, when the mounting plate 301 moves, the upper sliding plate 302 and the lower sliding plate 303 at its upper and lower ends will slide along the outer side of the limiting rod 304 and the threaded rod 305, thereby limiting the movement of the mounting plate 301.

[0028] An adjusting ring 306 is connected to the outer end of the threaded rod 305. The adjusting ring 306 has an internal thread on its inner side. The outer side of the threaded rod 305 is threaded to the inner side of the adjusting ring 306. The outer side of the adjusting ring 306 abuts against the left and right sides of the lower sliding plate 303. Thus, after moving each mounting plate 301 inside the device housing 1, rotating the adjusting ring 306 to move it to the left and right sides of the lower sliding plate 303 allows each lower sliding plate 303 to be fixed between the adjusting rings 306. This allows the positions of each mounting plate 301 inside the device housing 1 to be adjusted and then re-fixed, facilitating the adjustment of the spacing between the mounting plates 301 to a suitable installation distance based on the length of the component to be installed.

[0029] The wire harness mechanism includes a base plate 401 fixedly connected to the bottom of the inner side of the device housing 1. Round rods 402 are fixedly connected at equal intervals to the upper front end of the base plate 401. A top plate 403 is welded to the upper end of the round rods 402. A spring 404 is fixedly connected to the lower side of the top plate 403. A movable plate 405 is fixedly connected to the lower end of the spring 404. A U-shaped plate 406 is fixedly connected to the rear end of the movable plate 405. A round hole is opened in the middle of the movable plate 405. The outer side of the round rods 402 is slidably connected to the inner side of the round hole. Therefore, when the spring 404 springs, it can drive the movable plate 405 to slide along the outer side of the round rods 402, thus limiting the movement of the movable plate 405.

[0030] The lower side of the U-shaped plate 406 abuts against the upper side of the base plate 401. When installing components onto the outer end of the mounting plate 301, first pull up the U-shaped plate 406, then place the wires at the outer ends of each component on the lower end of the U-shaped plate 406 above the base plate 401. Next, release the U-shaped plate 406, and the spring 404 rebounds and pushes down the moving plate 405, causing the U-shaped plate 406 to move down to contact the upper side of the base plate 401. This confines the wires within the U-shaped plate 406, neatly restraining the wires inside the device housing 1 within the U-shaped plate 406, facilitating the disassembly and repair of components inside the device housing 1 in case of device malfunction.

[0031] Working principle: When installing the components for intelligent monitoring of switchgear pulse current inside the device housing 1, first, according to the length of the components to be installed, move each mounting plate 301 to a suitable distance. Then, rotate the adjusting ring 306 to move it to the left and right sides of the lower sliding plate 303 to fix the mounting plate 301. Next, by passing the bolts through the components to be installed and threading them into the threaded holes inside the mounting plate 301, the installation of the components is completed. Then, the cover 2 is installed to the front end of the device housing 1 by bolts, completing the assembly of the intelligent monitoring device for switchgear pulse current.
