为了使本技术领域的人员更好地理解本发明方案,下面结合附图和具体实施方式对本发明作进一步的详细说明。The present invention will be further described in detail below in conjunction with the drawings and embodiments.
本实施例中所公开的柜体母线供电连接密封结构中,包括伸出柜体侧板1的柜体母线2,和与柜体母线2相连的外部供电线缆3,如图1至图3中所示,除此之外,本实施例所公开的方案中,还在柜体侧板1外侧设置了防护盒体4,并且柜体母线2和外部供电线缆3的接头被密封在防护盒体4内。In the cabinet busbar power supply connection sealing structure disclosed in this embodiment, the cabinet busbar 2 extending from the cabinet side panel 1 and the external power supply cable 3 connected to the cabinet busbar 2 are as shown in FIG. 1 to FIG. As shown in the above, in the solution disclosed in the embodiment, the protective box body 4 is also disposed outside the cabinet side panel 1, and the joints of the cabinet bus bar 2 and the external power supply cable 3 are sealed in protection. Inside the box 4.
由于柜体母线2和外部供电线缆3的接头被密封在了防护盒体4内,因此可以有效避免杂物和雨水进入到两者的接头位置,从而有效提高了两者接头位置的安全防护等级,提升了设备工作的可靠性。Since the joints of the cabinet bus bar 2 and the external power supply cable 3 are sealed in the protective box body 4, it is possible to effectively prevent the debris and rainwater from entering the joint position of the two, thereby effectively improving the safety protection of the joint positions of the two. Levels improve the reliability of equipment work.
如图1中所示,防护盒体4上开设有供外部供电线缆3穿过的通孔,并且在通孔内嵌装有柔性过线圈5,该柔性过线圈5一方面能够紧套在外部供电线缆3上,另一方面能够利用其自身的形变与防护盒体4上的通孔实现密封。本领域技术人员容易理解的是,柔性过线圈5的选择并不局限于一种,例如橡胶过线圈、硅胶过线圈等均可。As shown in FIG. 1, the protective case 4 is provided with a through hole through which the external power supply cable 3 passes, and a flexible over-coil 5 is embedded in the through hole, and the flexible over-coil 5 can be tightly fitted on the one hand. On the other hand, on the external power supply cable 3, on the other hand, it is possible to seal with the through hole on the protective casing 4 by its own deformation. It will be readily understood by those skilled in the art that the selection of the flexible over-coil 5 is not limited to one type, such as a rubber over-coil, a silicone over-coil, or the like.
柜体母线2可能为铜排,通常情况下该铜排采用高纯度紫铜制成,通过机械加工完成铜排形状的加工,铜排的形状通常为长方形,在柜体母线2为铜排的情况下,柜体侧板1内侧还设置有第一电木6和第二电木7,并且第一电木6和第二电木7扣合之后形成与铜排密封配合的夹装槽。如图1中所示,柜体母线2为两个铜排,第一电木6和第二电木7上开设有槽口,当第一电木6
和第二电木7扣合后,槽口刚好与铜排适配,从而完成对铜排的夹持固定。加工在电木上的槽理想状态下应当与铜排的横截面完全一致,以便达到预期的密封效果。The busbar 2 of the cabinet may be a copper row. Usually, the copper row is made of high-purity copper, and the shape of the copper row is processed by machining. The shape of the copper row is usually rectangular, and the busbar 2 is a copper row. Next, the first bakelite 6 and the second bakelite 7 are further disposed on the inner side of the cabinet side panel 1, and the first bakelite 6 and the second bakelite 7 are fastened to form a clamping slot that is sealingly engaged with the copper row. As shown in FIG. 1, the cabinet bus bar 2 is two copper bars, and the first bakelite 6 and the second bakelite 7 are provided with slots, when the first bakelite 6
After being fastened with the second bakelite 7, the notch is just fitted with the copper bar, thereby completing the clamping and fixing of the copper bar. The groove machined on the bakelite should ideally conform to the cross section of the copper row in order to achieve the desired sealing effect.
需要说明的是,在本发明中,所谓柜体侧板1外侧是指柜体侧板1位于柜体外部的一面,柜体侧板1内侧是指柜体侧板1位于柜体内部的一面。It should be noted that, in the present invention, the outer side of the cabinet side panel 1 refers to the side of the cabinet side panel 1 located outside the cabinet body, and the inner side of the cabinet side panel 1 refers to the side of the cabinet side panel 1 located inside the cabinet body. .
至此,柜体母线供电连接密封结构实际上形成了双级密封结构,分别为柜体侧板1外部的防护盒密封和柜体侧板1内部的电木密封,相比于现有技术中仅有电木密封的单级密封结构而言,双级密封结构的防护性能大大提升。So far, the cabinet busbar power supply connection sealing structure actually forms a double-stage sealing structure, which is respectively a protective box seal outside the cabinet side panel 1 and a bakelite seal inside the cabinet side panel 1, compared to the prior art only In the case of a single-stage sealing structure with a bakelite seal, the protection performance of the two-stage sealing structure is greatly improved.
优选的,第一电木6和第二电木7均通过螺栓9与柜体侧板1连接,如图1至图3中所示,当然第一电木6和第二电木7还可通过卡装等方式与柜体侧板1连接,本文中对此不作具体限定。更进一步的,为了提高电木与柜体侧板1连接位置的密封性,还可在第一电木6与柜体侧板1之间,以及第二电木7与柜体侧板1之间均设置密封垫。Preferably, the first bakelite 6 and the second bakelite 7 are connected to the cabinet side panel 1 by bolts 9, as shown in FIGS. 1 to 3, of course, the first bakelite 6 and the second bakelite 7 may also be It is connected to the side panel 1 of the cabinet by means of card loading or the like, which is not specifically limited herein. Further, in order to improve the sealing property of the connection position of the bakelite and the cabinet side panel 1, the first bakelite 6 and the cabinet side panel 1 and the second bakelite 7 and the cabinet side panel 1 may be A gasket is provided between each.
不难理解的是,当柜体母线2为铜排时,外部供电线缆3可以直接与铜排拧紧连接,或者焊接,在本实施例中,外部供电线缆3与铜排之间采用螺栓连接,具体的,外部供电线缆3穿入防护盒体4内的一端上压接有连接片8,如图1中所示,该连接片8为圆头接片,连接片8上开设有第一连接孔;柜体母线2伸出柜体侧板1的一端上开设有第二连接孔,穿过第一连接孔和所述第二连接孔的螺栓将连接片8与柜体母线2连接,该种连接可靠性强,并且容易拆装。It is not difficult to understand that when the cabinet bus bar 2 is a copper bar, the external power supply cable 3 can be directly screwed or welded to the copper bar. In this embodiment, a bolt is used between the external power supply cable 3 and the copper bar. Specifically, the one end of the external power supply cable 3 penetrating into the protection box body 4 is crimped with a connecting piece 8 . As shown in FIG. 1 , the connecting piece 8 is a round head piece, and the connecting piece 8 is opened. a first connecting hole; a second connecting hole is formed on one end of the cabinet bus bar 2 extending from the side panel 1 of the cabinet, and the connecting piece 8 and the cabinet bus bar 2 are connected through the bolts of the first connecting hole and the second connecting hole Connection, this kind of connection is reliable and easy to disassemble.
当然,柜体母线2还可能为电缆,当柜体母线2为电缆时,柜体侧板1上开设有供电缆穿出的母线通孔,并且在母线通孔内嵌设有柔性过线圈5,该柔性过线圈5一方面能够紧套在作为柜体母线2的电缆上,另一方面还能够利用其自身的形变实现与母线通孔的密封配合。这同样使得柜体母线供电连接密封结构实现了双级密封,外部密封结构的密封原理和内部密封结构的密封原理一致,均是通过柔性过线圈5密封。Of course, the cabinet busbar 2 may also be a cable. When the cabinet busbar 2 is a cable, the cabinet side panel 1 is provided with a busbar through hole for the cable to pass through, and a flexible over coil 5 is embedded in the busbar through hole. On the one hand, the flexible over-coil 5 can be fastened over the cable as the cabinet busbar 2, and on the other hand it can also be sealed with the busbar-through opening by its own deformation. This also enables the cabinet busbar power supply connection sealing structure to achieve a two-stage seal. The sealing principle of the outer seal structure is consistent with the sealing principle of the inner seal structure, and is sealed by the flexible over coil 5.
容易连接的是,防护盒体4与柜体侧板1可以为可拆装连接,也可为永久性固定连接,在本实施例中,防护盒体4用于与柜体侧板1相接的一端设置有翻边,穿过翻边和柜体侧板1的固定螺钉将防护盒体4与柜体侧板1连接,该
种设置使得防护盒体4可以进行更换,当在不同的现场施工时,可以根据线缆直径的不同来更换与外部供电线缆3相匹配的防护盒体4。It is easy to connect that the protective box body 4 and the cabinet side panel 1 can be a detachable connection or a permanent fixed connection. In the embodiment, the protective box body 4 is used to connect with the cabinet side panel 1 One end is provided with a flange, and the protective box 4 is connected to the cabinet side panel 1 through a flange and a fixing screw of the cabinet side panel 1
