Description

一种用于输电高压电缆接头教学的复合套管组件A composite bushing assembly used for the teaching of power transmission high-voltage cable joints

技术领域 technical field

本发明涉及电力系统中的考核教学设备,具体涉及一种用于输电高压电缆接头教学的复合套管组件。 The invention relates to assessment and teaching equipment in electric power systems, in particular to a composite bushing assembly used for teaching of power transmission high-voltage cable joints.

背景技术 Background technique

电力公司作为国有特大型电力企业的典型代表,高度重视电缆接头工能力考评工作。高压电缆接头工全实操考评成本高昂,主要因为学员使用新套料进行练习或考核,增加了企业的成本负担,这是制约电缆接头工全实操考评的关键瓶颈之一。如图5所示,在实际工业使用的套管组件实施例中,套管组件包含带电运行部件及套管部件,其中,带电运行部件长度为1200mm、套管部件为1400mm,则管组件总高度为2600mm。并且套管采用陶瓷材料制成,使得套管组件重量约为600KG。套管组件内的电缆长度约为4.5m。如图7所示,用于套管组件的出线杆采用一体式结构,当不同人员进行考核时,出线杆为一次性使用材料,每次考核均需更换。套管组件的底板采用铜制成,重量约为73KG。将实际工业使用的套管组件用于输电高压电缆接头教学中时,由于现有技术中套管组件的带电运行部件不具有实际用途,且套管组件采用陶瓷材料制成,因此使得现有技术的套管组件重量较大、高度较高,则需要采用吊装协助完成教学培训;同时由于实际工业使用的套管组件的出线杆采用一体式结构,则每次教学培训后需要更换整根出线杆;因此大大增加了培训费用。针对以上问题,急需开发输电高压电缆接头考核专用套管终端,一方面确保不影响考评质量、不违反考评工艺,同时大幅降低考核成本,确保考评的公正性、安全性、高效性及经济性,实现考评工作常态化。 As a typical representative of state-owned super-large power companies, power companies attach great importance to the ability evaluation of cable connector workers. The high-voltage cable joint workmanship assessment is costly, mainly because the trainees use new sets of materials for practice or assessment, which increases the cost burden of the enterprise. This is one of the key bottlenecks restricting the cable joint workmanship assessment. As shown in Figure 5, in the embodiment of the bushing assembly used in the actual industry, the bushing assembly includes a live running part and a bushing part, wherein the length of the live running part is 1200mm, and the bushing part is 1400mm, then the total height of the pipe assembly It is 2600mm. And the sleeve is made of ceramic material, so that the weight of the sleeve assembly is about 600KG. The cable length inside the bushing assembly is approximately 4.5m. As shown in Figure 7, the outlet rod used for the bushing assembly adopts an integrated structure. When different personnel conduct assessments, the outlet rod is a one-time use material and needs to be replaced for each assessment. The bottom plate of the bushing assembly is made of copper and weighs about 73KG. When the bushing assembly used in the actual industry is used in the teaching of high-voltage cable joints for power transmission, because the live running parts of the bushing assembly in the prior art have no practical use, and the bushing assembly is made of ceramic materials, so the prior art The bushing assembly is heavy and high in height, so hoisting is required to assist in completing the teaching and training; at the same time, since the outlet rod of the bushing assembly used in the actual industry adopts an integrated structure, the entire outlet rod needs to be replaced after each teaching and training ; thus greatly increased training costs. In view of the above problems, it is urgent to develop a special bushing terminal for the assessment of transmission high-voltage cable joints. On the one hand, it will not affect the quality of the assessment, and will not violate the assessment process. At the same time, it will greatly reduce the assessment cost and ensure the fairness, safety, efficiency and economy of the assessment. Realize the normalization of evaluation work.

具体实施方式 Detailed ways

以下结合附图,通过详细说明一个较佳的具体实施例,对本发明做进一步阐述。 The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

如图1所示,一种用于输电高压电缆接头教学的复合套管组件,该复合套管2组件包含:顶盖1、复合套管2、电缆组件3、应力锥4、底板5及尾管组件6。 As shown in Figure 1, a composite casing assembly used for teaching high-voltage cable joints for power transmission, the composite casing 2 assembly includes: a top cover 1, a composite casing 2, a cable assembly 3, a stress cone 4, a bottom plate 5 and a tail Tube assembly6.

其中,复合套管2顶部与顶盖1连接;电缆组件3设置在复合套管2内;应力锥4设置在复合套管2内,套置在电缆组件3上;底板5设置在复合套管2底部,并与该复合套管2连接;尾管组件6设置在底板5上,并与电缆组件3连通。 Among them, the top of the composite casing 2 is connected to the top cover 1; the cable assembly 3 is arranged in the composite casing 2; the stress cone 4 is arranged in the composite casing 2 and placed on the cable assembly 3; the bottom plate 5 is arranged in the composite casing 2 bottom, and connected with the composite casing 2; the tail pipe assembly 6 is set on the bottom plate 5, and communicated with the cable assembly 3.

如图1所示,复合套管2包含:套管21、硅橡胶伞裙22,其中,套管21采用玻璃钢制成;电缆组件、应力锥设置在套管内;硅橡胶伞裙22,套设在所述套管外壁上。 As shown in Figure 1, the composite sleeve 2 includes: a sleeve 21 and a silicone rubber shed 22, wherein the sleeve 21 is made of FRP; the cable assembly and the stress cone are arranged in the sleeve; the silicone rubber shed 22 is sleeved on the outer wall of the casing.

本发明中,由于复合套管2采用玻璃钢、硅橡胶制成,安全性较好。同时相比于现有技术的输电高压电缆专用套管重量约为600KG,本发明中,复合套管总重量约为65KG左右,大大的减轻了套管组件的重量,在实际教学使用中能够做到轻盈、方便的安装使用,省去现场吊车,加强了考评的公平性和安全性。底板5采用铝质制成,比起现有技术能够节约成本,降低复合套管组件重量,同时能够提高使用安全性。 In the present invention, since the composite casing 2 is made of glass fiber reinforced plastic and silicon rubber, the safety is better. At the same time, compared with the weight of the special bushing for power transmission high-voltage cables in the prior art, which is about 600KG, in the present invention, the total weight of the composite bushing is about 65KG, which greatly reduces the weight of the bushing assembly, and can be used in actual teaching. Lightweight, convenient installation and use, eliminating the need for on-site cranes, and enhancing the fairness and safety of the evaluation. The bottom plate 5 is made of aluminum, which can save cost and reduce the weight of the composite casing assembly compared with the prior art, and can improve the safety of use at the same time.

如图6所示,本实施例中,复合套管2的总长度为1500mm,比起现有技术中(图5所示)2600mm缩减了1100mm的长度。由于实际使用的户外终端组件中有约1100mm左右的长度为保证爬电距离设计,而在培训中没有实际使用意义。因此缩短复合套管2的总长度,能够使得用户在使用的过程中能够更加安全。底板5采用铝质材料制成后,质量从现有技术的73KG降低为23.5KG。 As shown in FIG. 6 , in this embodiment, the total length of the composite sleeve 2 is 1500 mm, which is 1100 mm shorter than the 2600 mm in the prior art (shown in FIG. 5 ). Since the length of about 1100mm in the actually used outdoor terminal assembly is designed to ensure the creepage distance, it has no practical significance in training. Therefore, shortening the total length of the composite sleeve 2 can make the user safer during use. After the base plate 5 is made of aluminum material, the mass is reduced from 73KG in the prior art to 23.5KG.

如图1所示,电缆组件3包含:电缆31、出线杆32及第一热缩管33。其中,电缆31的中部套有应力锥4;出线杆32的一端设置在顶盖1外部,该出线杆32的另一端与电缆31的前端连接;第一热缩管33套置在电缆31的前端上;第一热缩管33内部有绝缘自粘带包成橄榄形。 As shown in FIG. 1 , the cable assembly 3 includes: a cable 31 , an outlet rod 32 and a first heat-shrinkable tube 33 . Wherein, the middle part of the cable 31 is covered with a stress cone 4; one end of the outlet rod 32 is arranged outside the top cover 1, and the other end of the outlet rod 32 is connected to the front end of the cable 31; On the front end; the inside of the first heat-shrinkable tube 33 is wrapped in an olive shape with an insulating self-adhesive tape.

本发明中,由于复合套管2的总长度相比于现有技术的套管总长度进行了缩短,则电缆31的长度由现有技术的4.5m缩减到3.3m,节约了电缆长度,降低了考核成本,同时减少了电缆处理时间,缩短了考评周期。 In the present invention, since the total length of the composite casing 2 is shortened compared with the total length of the casing of the prior art, the length of the cable 31 is reduced from 4.5m of the prior art to 3.3m, which saves the cable length and reduces It reduces the assessment cost, reduces the cable processing time, and shortens the assessment cycle.

现有技术中,户外终端组件总重量大于在600KG左右。本实施例中,如图1所示,复合套管2将现有技术中的套管的陶瓷材料改为玻璃钢制成的套管21、硅橡胶制成的硅橡胶伞裙22及设置在复合套管2顶部及底部的铝合金法兰23组成,并缩短复合套管2长度,同时缩短了电缆31长度后,复合套管组件总重量缩减到65KG左右,大大降低了考核用复合套管组件总重量。因此本发明在实际考核中,无需采用现场吊车、加强了考评公平性、安全性。 In the prior art, the total weight of outdoor terminal components is greater than about 600KG. In this embodiment, as shown in Figure 1, the ceramic material of the bushing in the prior art is changed into a bushing 21 made of glass fiber reinforced plastics, a silicone rubber shed 22 made of silicon rubber, and a composite bushing 2 arranged on the composite bushing 2. The top and bottom of the casing 2 are composed of aluminum alloy flanges 23, and the length of the composite casing 2 is shortened. After shortening the length of the cable 31, the total weight of the composite casing assembly is reduced to about 65KG, which greatly reduces the weight of the composite casing assembly for assessment. gross weight. Therefore, the present invention does not need to use an on-site crane in the actual assessment, which enhances the fairness and safety of the assessment.

如图2所示,出线杆32包含:安装杆321、压接杆322。其中,安装杆321的顶部设置在顶盖1外部,该安装杆321的底部设置在复合套管2内。压接杆322设置在复合套管2内;压接杆322的底部与电缆31的前端连接,该压接杆322的顶部与设置在复合套管2内的安装杆321的底部连接。 As shown in FIG. 2 , the outlet rod 32 includes: a mounting rod 321 and a crimping rod 322 . Wherein, the top of the installation rod 321 is arranged outside the top cover 1 , and the bottom of the installation rod 321 is arranged inside the composite casing 2 . The crimping rod 322 is arranged in the composite casing 2 ; the bottom of the crimping rod 322 is connected to the front end of the cable 31 , and the top of the crimping rod 322 is connected to the bottom of the installation rod 321 arranged in the composite casing 2 .

安装杆321底部设有安装部件3211,用于与压接杆322进行活动连接;压接杆322顶部设有安装卡槽3221,安装部件3211设置在安装卡槽3221内。本发明中,安装杆321采用铝制成,压接杆322采用铜制成。 A mounting part 3211 is provided at the bottom of the mounting rod 321 for movably connecting with the crimping rod 322 ; In the present invention, the mounting rod 321 is made of aluminum, and the crimping rod 322 is made of copper.

出线杆32从现有技术(图7所示)的一体化设计改为分段化设计,将出线杆32分为安装杆321、压接杆322,能够满足压接工艺和安装工序的要求。当不同人员进行考核时,压接杆322为一次性使用材料,每次考核均需更换。由于安装杆321与压接杆322通过安装部件3211、安装卡槽3221进行活动连接,则安装杆321在每次更换压接杆322后,仅需要将同一安装杆321连入对应的压接杆322即可完成出线部分的连接。本实施例中,安装部件3211、安装卡槽3221之间采用螺纹进行连接。 The outlet rod 32 is changed from the integrated design of the prior art (shown in FIG. 7 ) to a segmented design, and the outlet rod 32 is divided into a mounting rod 321 and a crimping rod 322, which can meet the requirements of the crimping process and installation process. When different personnel conduct assessments, the crimping rod 322 is a disposable material and needs to be replaced for each assessment. Since the mounting rod 321 and the crimping rod 322 are movably connected through the mounting part 3211 and the mounting slot 3221, after the mounting rod 321 replaces the crimping rod 322 each time, only the same mounting rod 321 needs to be connected to the corresponding crimping rod 322 to complete the connection of the outlet part. In this embodiment, the installation part 3211 and the installation slot 3221 are connected by threads.

本实施例中,安装杆321的长度为200mm,压接杆322长度为100mm。 In this embodiment, the length of the mounting rod 321 is 200 mm, and the length of the crimping rod 322 is 100 mm.

如图1所示,尾管组件6包含:尾管61、第二热缩管62。其中,尾管61的一端设置在底板5内,该尾管61的另一端设置在该底板5外部;电缆31靠近复合套管2底部的部分设置在尾管61内。电缆31的尾端设置在该尾管61外部。将尾管61与电缆31的金属护套采用铅封连接固定,并将第二热缩管62套置在尾管61与电缆31的金属护套上。 As shown in FIG. 1 , the tail pipe assembly 6 includes: a tail pipe 61 and a second heat shrinkable tube 62 . Wherein, one end of the tail pipe 61 is arranged in the bottom plate 5 , and the other end of the tail pipe 61 is arranged outside the bottom plate 5 ; the part of the cable 31 close to the bottom of the composite casing 2 is arranged in the tail pipe 61 . The tail end of the cable 31 is disposed outside the tail pipe 61 . The tail pipe 61 and the metal sheath of the cable 31 are connected and fixed with a lead seal, and the second heat-shrinkable tube 62 is sleeved on the tail pipe 61 and the metal sheath of the cable 31 .

如图1所示,电缆31的外护套全部剥除。电缆31从与出线杆32连接的一端至应力锥4根部,要将该部分电缆31的绝缘屏蔽层剥除。 As shown in FIG. 1, the outer sheath of the cable 31 is completely stripped off. The cable 31 is from one end connected to the outlet rod 32 to the root of the stress cone 4, and the insulation shielding layer of this part of the cable 31 should be stripped off.

出线杆32与剥除绝缘屏蔽层的电缆31的一端通过压接固定。应力锥4与剥除绝缘屏蔽层的电缆31的一段通过润滑剂接触润滑从而安装到工艺位置。 The outlet bar 32 is fixed to one end of the cable 31 with the insulation shielding layer stripped off by crimping. The stress cone 4 and a section of the cable 31 stripped of insulation and shielding layer are lubricated by lubricant contact and installed to the process position.

本发明公开的一种用于输电高压电缆接头教学的复合套管组件,能够独立完成考核,实现考核的经济性、公正性、安全性及高效性。同时考核用复合套管组件由于质量远远轻于实际使用的套管组件,在考核过程中无需使用吊车辅助考核完成,实现了人员考核的经济性、安全性。再次,出线杆32采用分体式结构,使得安装杆321能够反复利用,提高考核的经济性。 The composite bushing assembly disclosed by the invention is used for the teaching of high-voltage cable joints for power transmission, which can independently complete the assessment and realize the economy, fairness, safety and high efficiency of the assessment. At the same time, because the quality of the composite bushing assembly used for the assessment is far lighter than that of the actual casing assembly, there is no need to use a crane to assist the assessment during the assessment process, which realizes the economy and safety of the personnel assessment. Thirdly, the outlet rod 32 adopts a split structure, so that the installation rod 321 can be used repeatedly, improving the economy of the assessment.

The weight of the composite casing assembly is reduced from approximately 600KG in the prior art to approximately 65KG by changing the material, so that personnel do not need to use a crane for hoisting during training or teaching, and realize the economy and safety of teaching or training. The length of the cable in the composite bushing assembly is shortened from about 4.5m in the prior art to about 3.3m, so that the personnel saves cables during the training or teaching process and realizes the economy of teaching or training. Changing the outlet rod 32 from a one-piece structure to a split structure can make 2/3 of the material of the outlet rod 32 reusable, realizing the economy in the process of training or teaching. The weight of the base plate 5 is reduced from about 73KG in the prior art to about 23.5KG by changing the material (changing the copper base plate in the prior art to an aluminum alloy base plate), which reduces the weight of the base plate 5 in the process of training or teaching. Light weight, easy installation, improved economy and safety.

如图4所示,采用本发明提供的用于输电高压电缆接头教学的复合套管组件,能够减少吊装费用600元/人次;能够将现有技术中的电缆31从长度约为4.5m缩短为本发明的约为3.3m,降低了1174.8元/人次的教学成本;由于改变出线杆32为分体式结构,能够将其中的三分之二部分重复利用,因此降低了830元的教学成本;由于改变复合套管2的材料、长度,能够降低了695元/人次;由于改变底板5的材料,能够降低150元/人次的教学成本。也即,本发明能够在每次教学过程中大约节约3500元/人次。 As shown in Figure 4, adopting the composite bushing assembly provided by the present invention for the teaching of power transmission high-voltage cable joints can reduce the hoisting cost by 600 yuan/person; the cable 31 in the prior art can be shortened from about 4.5m in length to The present invention is about 3.3m, which reduces the teaching cost of 1174.8 yuan/person; because the outlet pole 32 is changed to a split structure, two-thirds of which can be reused, thus reducing the teaching cost of 830 yuan; Changing the material and length of the composite casing 2 can reduce 695 yuan/person; the teaching cost of 150 yuan/person can be reduced by changing the material of the bottom plate 5. That is to say, the present invention can save about 3500 yuan/person in each teaching process.
