Description

Technical Field

[0001] This application relates to the field of power distribution equipment, and more particularly to a combined high-explosive power distribution device with a detachable connector. Background Technology

[0002] Power distribution equipment is a combination of electrical devices used in a power system to receive, distribute, and control electrical energy. It is widely used in power plants, substations, industrial and mining enterprises, buildings, and other places.

[0003] Existing power distribution equipment is an independent unit. This type of power distribution equipment is connected to other power distribution equipment through junction boxes, resulting in low integration and large space occupation. Utility Model Content

[0004] To reduce the space occupied by the power distribution device, this application provides a combined high-explosive power distribution device with a detachable connector.

[0005] This application provides a combined high-explosive power distribution device with a detachable connector, which adopts the following technical solution:

[0006] A combined high-explosive power distribution device with a detachable connector includes a housing, within which multiple power distribution components are arranged in two groups, which are arranged vertically. The housing has two sets of cable passages corresponding to the power distribution components, which are used for cables to enter and exit the housing. The housing has a mounting plate with through holes communicating with the cable passages. Wiring components are detachably connected to the mounting plate.

[0007] By adopting the above technical solution, multiple power distribution components are divided into two groups and arranged vertically, i.e., the power distribution components are distributed in upper and lower layers, which optimizes space utilization and achieves a high degree of integration of the power distribution device. Under the premise of setting a large number of power distribution components, the horizontal space occupied by the power distribution device is reduced. At the same time, through the through holes and detachable wiring components on the mounting plate, flexible cable entry and exit and quick assembly and disassembly of wiring components are realized. Different wiring components can be connected on the mounting plate according to the actual needs of customers, which improves the integration and applicability of the device.

[0008] Optionally, the wiring assembly includes a wiring sleeve with a through hole for the cable to pass through, and the wiring sleeve is detachably connected to the mounting plate by a bolt assembly.

[0009] By adopting the above technical solution and using the bolt connection between the junction box and the mounting plate, the wiring assembly is made detachable, which facilitates maintenance and replacement. At the same time, it ensures the stability and safety of the cable connection and simplifies the installation and disassembly process.

[0010] Optionally, the wiring assembly further includes a wire guide tube disposed in the wire guide hole of the wiring tube. The wire guide tube has multiple layers and has an inner cavity that extends through both axial ends of the wire guide tube. The multiple wire guide tubes are detachably sleeved together radially.

[0011] By adopting the above technical solution, and by setting multiple layers of detachable cable guides in the cable guide hole of the cable guide, it is possible to adapt to cables of different diameters, thereby enhancing the versatility and adaptability of the device. At the same time, it is convenient to adjust the number of layers of the cable guide according to actual needs.

[0012] Optionally, the wire guide spools are made of elastic material, and adjacent wire guide spools are interference-fitted.

[0013] By adopting the above technical solution, the cable guide tube is made of elastic material and is connected to adjacent cable guide tubes by interference fit. The unwanted cable guide tubes can be stripped out according to the different diameters of the cables, leaving the required cable guide tubes, which makes it easy to adjust the actual hole diameter of the cable guide tubes. It also ensures that the cables are tightly fixed in the cable guide holes, effectively preventing the cables from loosening or falling off, and reducing the wear of the cables caused by vibration or external force.

[0014] Optionally, the wiring assembly further includes a shielding pad for blocking the opening on the axial end face of the wire guide, the shielding pad being disposed on the side of the wire guide away from the housing.

[0015] By adopting the above technical solution, and by setting a shielding pad on the side of the cable tray away from the housing, it is possible to prevent external contaminants such as dust and moisture from entering the housing through the cable tray during transportation after the power distribution device is manufactured and before the cables are connected. This protects the internal structure of the housing, extends the service life of the power distribution device, and improves safety.

[0016] Optionally, the wiring assembly further includes a wire clamp, which is detachably connected to the wiring sleeve. The wire clamp has a through hole for the cable to pass through, and a clamping structure for clamping and fixing the cable.

[0017] By adopting the above technical solution, the cable clamp and the clamping structure work together to clamp and fix the cable, preventing the cable from sliding or loosening in the wire hole, thus ensuring the stability of the cable connection. At the same time, the detachable design of the clamp facilitates maintenance and adjustment.

[0018] Optionally, the wire clamping structure includes a wire clamping head located on the side of the wire clamping base away from the housing. The wire through hole extends to and passes through the wire clamping head. The wire clamping structure also includes a wire clamping plate bolted to the wire clamping head. An installation groove communicating with the wire through hole is provided on the outer circumferential surface of the wire clamping head. The installation groove extends circumferentially along the wire clamping head. The wire clamping plate is used to pass through the installation groove and extend into the wire through hole. The wire clamping plate is used to clamp and fix the cable to the hole wall of the wire through hole.

[0019] By adopting the above technical solution, the cable can be firmly clamped to the wall of the wire-passing hole through the cooperation of the clamping plate and the mounting groove, preventing the cable from shifting or falling off due to external force. At the same time, the clamping plate is bolted to the clamping head, and the bolt screwing depth can be adjusted according to the cable diameter, thereby improving the applicability of the clamping structure.

[0020] Optionally, the shielding pad is made of an elastic material, and the wiring assembly further includes a mounting ring, with the wire clamp used to press the mounting ring against the shielding pad.

[0021] By adopting the above technical solution and using a shielding pad made of elastic material, the shielding pad does not need to be removed when connecting cables. The cable can simply pierce through the shielding pad and pass through, which is convenient. Since the shielding pad is made of elastic material, if the cable clamp is pressed directly on the shielding pad, it will cause the cable clamp to be fixed unevenly. By placing the mounting ring between the shielding pad and the cable clamp, the cable clamp can be fixed flat and will not affect subsequent use.

[0022] Optionally, the housing is provided with rollers, and the side wall of the housing is provided with a pulling member, and the pulling member is provided with a hook hole for the pull hook to pass through.

[0023] By adopting the above technical solution, and by setting rollers and pulling parts on the housing, the entire power distribution device can be moved and positioned easily, especially in narrow or complex spaces, which improves the portability and flexibility of use of the device. At the same time, the hook hole design of the pulling parts makes it easy to use with external tools.

[0024] Optionally, a lifting ring is provided on the upper surface of the housing.

[0025] By adopting the above technical solution and setting lifting rings on the shell, it is convenient to use lifting equipment to lift and transport the device, which significantly improves the convenience and safety of operation, especially in the installation and maintenance of large or heavy power distribution equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By dividing the power distribution components into upper and lower layers, the space utilization is optimized. Different wiring components can be connected on the mounting plate according to the actual needs of customers, which improves the integration and applicability of the device.

[0028] 2. By setting multiple layers of detachable cable trays in the cable tray's cable passage hole, it can accommodate cables of different diameters, enhancing the device's versatility and adaptability, while also making it easy to adjust the number of cable tray layers according to actual needs.

[0029] 3. The cable clamping plate and the mounting groove work together to firmly clamp the cable to the wall of the cable hole, preventing the cable from shifting or falling off due to external force. At the same time, the cable clamping plate is bolted to the clamping head, and the bolt insertion depth can be adjusted according to the cable diameter, improving the applicability of the clamping structure.
