一种用于模块化二次组合设备的线缆快速连接结构A cable quick connection structure for modular secondary combination equipment

技术领域 technical field

背景技术 Background technique

根据国家电网公司提出的“标准化设计、工厂化加工、装配式建设”的核心理念,目前正大力推广标准配送式变电站的建设,这样可以减少工程实际占地面积、方便现场安装、简化现场接线、便于现场检修维护。目前室内标准配送式变电站二次设备部分主要采用模块化二次组合设备的建设模式,如图1所示,将多台二次设备机柜通过一定的结构形式,固定在同一基础框架之上,使这些机柜间的连线在基础框架内的架空层通过下进线的方式进行连接,利用预制线缆将模块化二次组合设备机柜内的设备与外部设备进行连接。 According to the core concept of "standardized design, factory processing, and assembled construction" proposed by the State Grid Corporation of China, the construction of standard distribution substations is being vigorously promoted, which can reduce the actual area of the project, facilitate on-site installation, simplify on-site wiring, It is convenient for on-site inspection and maintenance. At present, the secondary equipment part of indoor standard distribution substation mainly adopts the construction mode of modularized secondary combined equipment. As shown in Figure 1, multiple secondary equipment cabinets are fixed on the same basic frame through a certain structural form, so that The connection between these cabinets is connected through the way of down-entry in the overhead layer in the basic frame, and the equipment in the modular secondary combination equipment cabinet is connected with the external equipment by using prefabricated cables.

目前有以下几种方式实现模块化二次组合设备与外部设备的线缆连接:(1)采用了单端预制线缆,在模块化二次组合设备机柜内部通过端子连线,现场连线工作量大、周期长,对连接技术要求较高,无法实现即插即用,且错误率较高;而且外部线缆进入模块化二次组合设备内后,需要通过基础框架内的走线槽盒行线,使内、外部线缆产生了交叉,易产生线缆间的电气干扰,同时接线工作也对原有内部线缆产生不利影响,可能造成内部线缆的连接松动或脱落,如图2和图3所示;(2)为了提升现场接线效率,采用了双端预制线缆。将预制线缆插座安装于模块化二次组合设备屏柜内部,占用了屏柜内部空间。外部线缆进入模块化二次组合设备内后,需要通过基础框架内的走线槽盒行线,使内、外部线缆产生了交叉,易产生线缆间的电气干扰,同时接线工作也对原有内部线缆产生不利影响,可能造成内部线缆的连接松动或脱落,如图4和图5所示。 At present, there are several ways to realize the cable connection between the modular secondary combination equipment and the external equipment: (1) Single-ended prefabricated cables are used, and the terminals are connected inside the modular secondary combination equipment cabinet, and the on-site connection work The quantity is large, the cycle is long, the connection technology is high, plug and play cannot be realized, and the error rate is high; and after the external cables enter the modular secondary combination equipment, they need to pass through the wiring trough box in the basic frame The internal and external cables are crossed, which is easy to cause electrical interference between the cables. At the same time, the wiring work also has an adverse effect on the original internal cables, which may cause the connection of the internal cables to loosen or fall off, as shown in Figure 2 and as shown in Figure 3; (2) In order to improve the field wiring efficiency, a double-ended prefabricated cable is used. The prefabricated cable socket is installed inside the screen cabinet of the modular secondary combination equipment, occupying the internal space of the screen cabinet. After the external cables enter the modular secondary combination equipment, they need to be routed through the wiring trough box in the basic frame, so that the internal and external cables cross, which is easy to cause electrical interference between cables, and the wiring work is also harmful The original internal cables have adverse effects, which may cause the connection of the internal cables to loosen or fall off, as shown in Figure 4 and Figure 5.
