- High-voltage cross-linked polyethylene insulated power cables are important infrastructure for power transmission, especially for power transmission across large sea areas. Since it is impossible to lay overhead lines, the use of high-voltage cross-linked polyethylene insulated submarine cables has become an inevitable choice.
- continuous length is one of the basic requirements. Since the manufacturing length of a single cable is limited and the laying of submarine cables requires that prefabricated cable intermediate joints should not be used as much as possible, in order to achieve sufficient transmission distance, submarine cable factory joints must be used to connect multiple cable sections to the required length. This submarine cable factory joint is also called a factory soft joint.
- the applicant also found that in the related technology, before extruding the insulation, the core and inner shielding layer of the two cable sections must be connected first, and the insulation layer near the connection of the two cable sections will be cut into a "pencil head" shaped reaction force cone, and then the process of "extruding cross-linkable polyethylene material and high temperature and high pressure insulation cross-linking" will be carried out.
- This process is recognized as the most difficult and most critical link for submarine cable factory joints.
- the conductor core is generally preheated first, and then the insulation is extruded into the mold cavity through the injection port while the external mold is heated at the same time.
- the temperature of this process must be strictly controlled and must not be too high, otherwise the material will cross-link too early and affect the insulation quality, and must not be too low, otherwise the material will lose fluidity. Afterwards, after the extrusion process is completed, the heating temperature of the mold will be increased, and under sufficient pressure, the material will undergo a cross-linking reaction in the mold. Similarly, the temperature of this process must also be strictly controlled. Too high a temperature will cause material aging, and too low a temperature will cause insufficient cross-linking of the material. It should be emphasized that in the process of manufacturing submarine cable factory joints, since the structure includes cables, molds and joint insulation at the same time, and the insulation is injected by flow, the temperature distribution at different positions in the above structure will be very complicated.
- the various operating steps of the above process are mainly determined by the fixed scheme explored by technicians in the early stage or based on field experience.
- the temperature of the key parts of the submarine cable factory joint will no longer conform to previous experience, and there will be a large temperature control deviation.
- the temperature is too high, it will cause overheating aging or deformation during the processing of the insulation material.
- the temperature of the key parts of the submarine cable factory joint can no longer be predicted based on experience, and there is no way to know what changes have occurred in the temperature of the submarine cable factory joint, which is very likely to have a negative impact on the subsequent production of the submarine cable factory joint and its overall insulation quality.
- the applicant has proposed a submarine cable factory joint measurement method after research, which can determine the temperature measurement value of each reference key area as the temperature measurement value of the corresponding measurement key area in the target submarine cable factory joint.
- the reference submarine cable factory joint and the target submarine cable factory joint are placed side by side at a preset distance to avoid electromagnetic signal interference between the two, and the two are in a consistent electromagnetic environment and ambient temperature environment.
- the main structure of the designed reference submarine cable factory joint is the same as that of the target submarine cable factory joint (the difference in the structure of the reference joint is only that a relatively small temperature sensor and its lead wires are added, so it is only necessary to open a number of narrow lead wire outlets in the closed mold to achieve this.
- the lead wires and the narrow lead wire outlets have a negligible impact on the electromagnetic environment and thermal field distribution of the joint due to their small size and light weight.
- the reference submarine cable factory joint and the target submarine cable factory joint are considered to have the same main structure), and since the reference submarine cable factory joint and the target submarine cable factory joint use the same heating source device to provide heating, the electromagnetic heating coils or resistance heating wires used to heat the two joints are wound in exactly the same manner and are connected to the same power supply in parallel or series, so that the two joints can be heated synchronously, avoiding problems such as temperature asynchrony and mismatch caused by fluctuations in the heating source parameters.
- the submarine cable factory joint measurement method provided in the embodiment of the present application is not limited to the above technical effects. Other technical effects can be found in the description below and will not be repeated here.
- a method for measuring the temperature of a submarine cable factory joint involves a process of obtaining the temperature measurement values of each reference key area of a reference submarine cable factory joint, and determining the temperature measurement values of each reference key area as the temperature measurement values of the corresponding measurement key area in the target submarine cable factory joint. This embodiment includes the following steps:
- the submarine cable factory joint in the embodiment of the present application is also called a soft joint, for example, it is a submarine cable factory joint for a high-voltage cross-linked polyethylene power cable.
- the target submarine cable factory joint refers to the submarine cable factory joint that currently needs to measure the temperature of the key area, which can be understood as the joint that is being formally produced in the actual application.
- the target submarine cable factory joint can be a submarine cable factory joint that is to be heated during the production process of the submarine cable factory joint, that is, the submarine cable factory joint that is currently to be heated.
- the target submarine cable factory joint can refer to a submarine cable factory joint that has completed the reaction force cone forming and grinding, conductor core welding (or crimping), conductor shielding wrapping and other steps, and is about to perform reaction force cone preheating and insulation recovery extrusion and other steps, or it can refer to a submarine cable factory joint that has completed the insulation recovery extrusion molding and other steps, and is about to perform insulation recovery heating cross-linking steps.
- the embodiment of the present application does not limit the link referred to by the target submarine cable factory joint, and it can be applicable to any submarine cable factory joint of any plastic insulated power cable.
- the key areas in the submarine cable factory joint include but are not limited to the reaction force cone insulation, the recovery conductor shield and the conductor core at the high-frequency induction coil.
- the reaction force cone and the recovery conductor shield are located in the middle of the cable of the submarine cable factory joint.
- a reference submarine cable factory joint is set to replace the target submarine cable factory joint to monitor the temperature of each key area in the target submarine cable factory joint.
- the reference submarine cable factory joint is a joint that replaces the target submarine cable factory joint to ensure the integrity and purity of the target submarine cable factory joint and to measure the temperature.
- the main structure of the reference submarine cable factory joint and the target submarine cable factory joint in the embodiment of the present application needs to be exactly the same, and the environment in which they are located must also be exactly the same, so as to ensure that the temperature of each area in the reference submarine cable factory joint can be more accurately equivalent to the temperature of the corresponding area in the target submarine cable factory joint.
- the reference submarine cable factory joint and the target submarine cable factory joint use the same heating source device to provide heating.
- the electromagnetic heating coils or resistance heating wires used to heat the two joints are wound in exactly the same manner and are connected to the same power supply in parallel or in series to achieve synchronous heating of the two joints.
- A is the target submarine cable factory joint A
- B is the reference submarine cable factory joint. According to the diagram in the figure, it can be seen that the main structure of the reference submarine cable factory joint is exactly the same as the main joint of the target submarine cable factory joint.
- the two need to be placed in the same environment.
- the reference submarine cable factory joint and the target submarine cable factory joint are placed side by side to ensure that they are in the same environment.
- both ends of the reference submarine cable factory joint and the target submarine cable factory joint are provided with electromagnetic coils, which naturally generate magnetic fields.
- a certain distance needs to be separated between the two. For example, the two joints are placed side by side after a distance of 0.5m to 1m.
- the length of the reference submarine cable factory joint and the target submarine cable factory joint does not need to be exactly the same, but the cable core has a conductive effect on heat.
- the total length of the cable part at both ends of the reference submarine cable factory joint can be set to at least 20m or more, and the cable lengths on both sides of the reference joint are equal (both are more than 10m).
- the reference key area refers to the key area in the reference submarine cable factory joint, which corresponds to the position of each key area in the target submarine cable factory joint.
- the temperature measurement values of each reference key area of the reference submarine cable factory joint can be obtained by installing a temperature measurement device in each reference key area of the reference submarine cable factory joint, and then obtaining the temperature measurement values of each reference key area of the reference submarine cable factory joint by reading the temperature measured by the temperature measurement device.
- the measured temperature value is directly determined as the temperature measurement value of the corresponding key area in the target submarine cable factory joint.
- the computer device obtains the temperature measurement value of each reference key area of the reference submarine cable factory joint, and determines the temperature measurement value of each reference key area as the temperature measurement value of the corresponding measurement key area in the target submarine cable factory joint. Since the main structure and the environment of the reference submarine cable factory joint and the target submarine cable factory joint are the same, and the reference submarine cable factory joint and the target submarine cable factory joint are placed side by side after being separated by a preset distance, the key area in the reference submarine cable factory joint can be completely equivalent to the key area in the target submarine cable factory joint, that is, the temperature distribution in the reference submarine cable factory joint and the target submarine cable factory joint is consistent, thereby realizing the accurate monitoring of the temperature of each key area in the target submarine cable factory joint during the heating process through the reference submarine cable factory joint.
- the temperature measurement of the key area in the embodiment of the present application is based on the precise temperature control of the heating link involved in the submarine cable factory joint manufacturing process, which is an important prerequisite for ensuring the high insulation quality of the target submarine cable factory joint. Therefore, when implementing the embodiment of the present application, the heating method of the reference submarine cable factory joint and the target submarine cable factory joint needs to be explained first.
- the heating of the reference submarine cable factory joint and the target submarine cable factory joint is achieved by a magnetic induction heating method, and the reference submarine cable factory joint and the target submarine cable factory joint both include an electromagnetic induction heating system, a metal cooling sleeve, and a metal heating mold.
- A is a target submarine cable factory joint
- B is a reference submarine cable factory joint
- 14 is an electromagnetic coil
- 15 is a conductor core
- 16 is an insulating material extrusion flow channel outlet
- 17 is a silicone rubber gasket
- 13 is a reaction force cone
- 12 is a metal heating mold
- 11 is a metal cooling jacket.
- the electromagnetic coils are placed symmetrically on both sides of the reference submarine cable factory joint and the target submarine cable factory joint to ensure that the temperature in the entire area of the reference submarine cable factory joint and the target submarine cable factory joint can be uniform.
- the reference submarine cable factory joint and the target submarine cable factory joint are consistent in terms of structure (except length) and heating device.
- the reference submarine cable factory joint and the target submarine cable factory joint include the same metal cooling jacket and the same metal heating mold.
- the metal heating mold is arranged outside the reaction force cone of the target submarine cable factory joint or the reference submarine cable factory joint; the metal cooling jacket is located on both sides of the metal heating mold and is in close contact with the metal heating mold and the outer side of the cable.
- the metal heating mold refers to the mold installed on the outside of the reaction force cone of the target submarine cable factory joint and the reference submarine cable factory joint.
- the mold can be a mold for extrusion insulation recovery or a mold for insulation recovery heating cross-linking. Its structure can be adjusted according to the needs of actual applications.
- the metal cooling sleeve is located on both sides of the metal heating mold and is in close contact with the metal heating mold and the outside of the cable. It is used to cool the cable insulation layer on both sides of the metal heating mold to prevent the insulation from being deformed due to excessive temperature. It is placed close to both sides of the metal heating mold and uses air cooling or water cooling to cool the cable insulation layer, so that the cables of the reference submarine cable factory joint and the target submarine cable factory joint will not be deformed due to insulation being heated.
- the insulation of the extrusion molds of the target submarine cable factory joint and the reference submarine cable factory joint can be restored to form the required shape, and the cable insulation layer on the outside of the extrusion mold can be cooled to prevent it from being deformed by heat.
- the induction heating system includes an electromagnetic coil and an induction heating power supply (not shown in FIG. 4 ); the electromagnetic coil is arranged on both sides of the metal cooling jacket, and the distance between the electromagnetic coil and the metal cooling jacket is greater than a preset distance.
- the electromagnetic coil can be a fixed coil with water cooling or a manually wound electromagnetic wire. It is located on both sides of the metal cooling jacket and has a preset distance with the metal cooling jacket. For example, the distance can be greater than or equal to 5 cm. This can prevent the magnetic field generated by the electromagnetic coil from causing excessive heating of the metal cooling jacket.
- the magnetic field it generates can penetrate the insulation shield and the insulation layer, causing the conductor core at the corresponding position of the electromagnetic coil to generate eddy currents and rapidly heat up, and then transfer heat to the conductor core at the joint of the submarine cable factory, causing the restoration conductor shield and the inner side of the reaction force cone to heat up.
- the temperature of the core of the cable at the joint of the submarine cable factory is achieved by controlling the output current and electric power of the induction heating power supply.
- the frequency of the output current of the induction heating power supply is between 1kHz and 50kHz.
- the frequency in this range can rapidly heat up the conductor core at the induction coil, and can ensure that the insulation shield at the electromagnetic coil will not heat up too high under the action of the magnetic field.
- the electric power of the induction heating power supply is controlled at more than 10kW, which can meet the rapid heating of the conductor core.
- an induction heating system is installed at the joint of the submarine cable factory, including an electromagnetic coil and an induction heating power supply.
- the output current and electric power of the induction heating power supply are used to rapidly heat up the conductor core at the electromagnetic coil, and then the heat is transferred to the conductor core at the joint of the submarine cable factory.
- the temperature of the inner side of the key areas of the submarine cable factory joint (such as the recovery conductor shield and the inner side of the reaction force cone) will increase, thereby achieving the heating effect of each key area in the submarine cable factory joint.
- Figure 5 is a temperature distribution cloud diagram of the reference submarine cable factory joint at 200 minutes in the preheating process, taking a cross-linked polyethylene insulated power cable reference submarine cable factory joint with a voltage level of 110kV and a copper conductor core section of 800mm2 as an example.
- Figure 5 is a temperature distribution cloud diagram of the reference submarine cable factory joint obtained by the simulation calculation method under the conditions of a current frequency of 15kHz, an effective value of 180A heating for 70 minutes, and an effective value of 140A heating for 130 minutes.
- the electromagnetic coil used in the target submarine cable factory joint is consistent with the reference submarine cable factory joint, and the current amplitude and frequency in the electromagnetic coil are consistent, so as to ensure that the electromagnetic induction heating has the same effect. Therefore, in the actual process, the electromagnetic coil can be implemented by an electromagnetic soft wire structure and powered by the same magnetic induction heating power supply.

通常,在海底电缆工厂接头制作工艺中,反应力锥绝缘和恢复导体屏蔽等部位的预热,以及恢复绝缘加热挤塑和加热交联等过程的精准控温,是保证海底电缆工厂接头绝缘高质量的重要前提。相关技术中,挤塑绝缘前预热,其操作步骤(包括加热方法和加热源功率控制)主要沿用技术人员前期摸索的固定方案或依据现场经验来确定。但是,加热过程中发生断电、室内温度变化或加热源功率不稳定等突发情况时,海底电缆工厂接头关键部位的温度也无法再依据经验预测,海底电缆工厂接头中的温度发生了哪些变化,也无从获知,这极有可能对海底电缆工厂接头的后续制作和其绝缘整体质量带来负面影响。

高压交联聚乙烯绝缘电力电缆是电力输送的重要基础设施,尤其对于跨大面积海域进行电力输送的情况,由于无法敷设架空线,采用高压交联聚乙烯绝缘海底电缆成为必然选择。对于高压交联聚乙烯海底电缆而言,连续长度是基本要求之一,由于单根电缆制造长度有极限,且海底电缆的敷设要求尽量不采用预制式电缆中间接头,为了实现足够的传输距离,就必须采用海底电缆工厂接头将多段电缆连接到所需的长度,这种海底电缆工厂接头也称工厂软接头。
然而,申请人经过对传统技术中的海底电缆工厂接头的研究发现,海底电缆工厂接头的制造技术难度极大,在有限的绝缘厚度限制之下,在电缆本体绝缘的完整性、一致性被破坏的前提下,难以实现可靠的长期工作性能。即使是有经验的电缆制造商,也不能完全保障海底电缆工厂接头的成功制造,制造成品率很低,一般高压海底电缆工厂接头需要制造几次甚至十几次才能有产品勉强通过型式试验。
进一步地,申请人还发现,相关技术中,挤塑绝缘前,需先完成两段电缆的线芯和内屏蔽层连接,两段电缆连接处附近的绝缘层将被削成“铅笔头”形状的反应力锥,随后将进行“挤塑可交联聚乙烯料和高温高压绝缘交联”这一工序,这一工序对于海底电缆工厂接头来说是公认难度最大、且最为关键的环节。在进行这一工序时,安装好模具和加热装置后,一般要先对导体线芯进行预热,然后在外部模具同时加热的情况下,将绝缘通过注塑口挤塑进入模具腔体,这一过程温度要严格控制,不得过高,否则会使材料过早发生交联而影响绝缘质量,不得过低,否则会使材料失去流动性。之后,在挤塑工序完成之后,将提高模具的加热温度,在足够的压力作用下,使材料在模具中发生交联反应,同样地,这一过程温度也要严格控制,温度过高将导致材料老化,温度过低将导致材料交联度不足。需要强调的是,海底电缆工厂接头制造过程中,由于结构上同时包括电缆、模具及接头绝缘,且绝缘又是流动注入的,因此在以上结构中不同位置的温度分布将是十分复杂的。为了保证电缆绝缘结构的完整性和高洁净度,海底电缆工厂接头加工制造过程中是不允许在其关键部位放置测温元件的。在一种技术中,以上工序的各个操作步骤(包括加热方法和加热源功率控制)主要沿用技术人员前期摸索的固定方案或依据现场经验来确定。但是,当电缆的结构和尺寸发生变化时,海底电缆工厂接头中的关键部位温度将不再符合以往的经验,会出现很大的温度控制偏差,温度过高时会导致绝缘材料加工中出现过热老化或变形,温度过低时会使电缆海底电缆工厂接头中出现严重的结构性缺陷(如气泡、绝缘材料密度低等);即便是电缆的结构和尺寸固定不变的前提下,若是海底电缆工厂接头加工的加热过程中发生断电、室内温度变化或加热源功率不稳定等突发情况时,海底电缆工厂接头关键部位的温度也无法再依据经验预测,海底电缆工厂接头中的温度发生了哪些变化,也无从获知,这极有可能对海底电缆工厂接头的后续制作和其绝缘整体质量带来负面影响。
传统技术中,海底电缆工厂接头制造过程的各个加热工艺环节中对于其关键区域温度缺乏有效的实时测量手段,这对于海底电缆工厂接头的加工工艺实时调节控制以及海底电缆工厂接头的工作可靠性造成了不利影响。
基于此,申请人经过研究提出一种海底电缆工厂接头测量方法,可以将各参考关键区域的温度测量值确定为目标海底电缆工厂接头中对应的测量关键区域的温度测量值。参考海底电缆工厂接头与目标海底电缆工厂接头之间相隔预设距离后并排放置,避免了二者之间的电磁信号干扰,二者处于一致的电磁环境和周围温度环境中。
且由于设计的参考海底电缆工厂接头与目标海底电缆工厂接头的主体结构相同(参考接头结构上的区别仅仅在于加设了体积相对很小的温度传感器及其接引线,因此只需对封闭性的模具开设若干狭小的接引线出口即可实现,接引线和狭小的接引线出口由于体积小、质量轻,对于接头的电磁环境和热场分布影响可以忽略,因此视为参考海底电缆工厂接头和目标海底电缆工厂接头具有一致的主体结构),又由于参考海底电缆工厂接头和目标海底电缆工厂接头采用相同的加热源装置提供加热,用于给两个接头加热的电磁加热线圈或电阻发热丝缠绕方式完全一致并通过并联或串联的方式连接到同一电源上,可以实现两个接头的同步加热,避免了加热源参数波动导致的温度不同步、不匹配等问题。
需要说明的是,本申请实施例提供的海底电缆工厂接头测量方法不限于是以上技术效果,其他的技术效果可参见下文描述,在此不再赘述。
下面对本申请实施例提供的海底电缆工厂接头温度测量方法进行说明。
在一个实施例中,如图2所示,提供了一种海底电缆工厂接头温度测量方法,本实施例涉及的是获取参考海底电缆工厂接头的各参考关键区域的温度测量值,将各参考关键区域的温度测量值确定为目标海底电缆工厂接头中对应的测量关键区域的温度测量值的过程。该实施例包括以下步骤:
S201,获取参考海底电缆工厂接头的各参考关键区域的温度测量值;参考海底电缆工厂接头与目标海底电缆工厂接头的主体结构和所处环境均相同,且参考海底电缆工厂接头与目标海底电缆工厂接头之间相隔预设距离后并排放置。
本申请实施例中的海底电缆工厂接头也被称为软接头,例如,其是一种高压交联聚乙烯电力电缆海底电缆工厂接头。
其中,目标海底电缆工厂接头指的是当前需要测量关键区域温度的海底电缆工厂接头,可理解为 实际应用中正在正式制作的接头。可选地,目标海底电缆工厂接头可以是在海底电缆工厂接头制作过程中待进行加热环节的海底电缆工厂接头,也即当前待加热的海底电缆工厂接头,该目标海底电缆工厂接头既可以是指已经完成反应力锥成型打磨、导体线芯焊接(或压接)、导体屏蔽绕包等步骤,即将进行反应力锥预热和恢复绝缘挤出等步骤的海底电缆工厂接头,也可以是指已完成恢复绝缘挤出成型等步骤,即将进行恢复绝缘加热交联步骤的海底电缆工厂接头。本申请实施例对目标海底电缆工厂接头指代的环节不作限定,其可适用任何一种塑料绝缘电力电缆的海底电缆工厂接头。
其中,海底电缆工厂接头中的关键区域包括但不限于反应力锥绝缘、恢复导体屏蔽以及高频感应线圈处的导体线芯等部位。其中,反应力锥和恢复导体屏蔽处于海底电缆工厂接头的电缆的中间位置。
实际应用中,考虑到海底电缆工厂接头绝缘结构完整性以及绝缘纯净度等限制,反应力锥绝缘、恢复导体屏蔽以及高频感应线圈处的导体线芯等部位是无法放置测温元件,基于此,本申请实施例中通过设置参考海底电缆工厂接头来替代目标海底电缆工厂接头来监测目标海底电缆工厂接头中各关键区域的温度。自然地,参考海底电缆工厂接头就是为保证目标海底电缆工厂接头的完整性和纯净度,来代替目标海底电缆工厂接头进行温度的测量的接头。
进一步地,可理解的是,本申请实施例中的参考海底电缆工厂接头与目标海底电缆工厂接头的主体结构是需要完全相同的,且所处环境还要完全相同,以保证参考海底电缆工厂接头中的各区域的温度可以更加精确地等效目标海底电缆工厂接头中对应区域的温度。
且本申请实施例中参考海底电缆工厂接头和目标海底电缆工厂接头采用相同的加热源装置提供加热,用于给两个接头加热的电磁加热线圈或电阻发热丝缠绕方式完全一致并通过并联或串联的方式连接到同一电源上,以实现两个接头的同步加热。
请参见图3所示,图3中的A为目标海底电缆工厂接头A,B为参考海底电缆工厂接头,根据图中示意可看出,参考海底电缆工厂接头的主体结构与目标海底电缆工厂接头主体接头完全一致。
为了保证参考海底电缆工厂接头和目标海底电缆工厂接头所处环境相同,需将两者放置于同一环境中,例如如图3中示意地,将参考海底电缆工厂接头和目标海底电缆工厂接头并排放置,保证其所处环境相同。另外,从图3中也可看出,参考海底电缆工厂接头和目标海底电缆工厂接头两端都是设置有电磁线圈,自然均会产生磁场,为了保证参考海底电缆工厂接头和目标海底电缆工厂接头并排放置后两者之间相互不受对方电磁线圈产生的磁场影响,两者之间需要间隔一定的距离,例如,两接头间隔0.5m~1m距离后并排放置。需要说明的是,本申请实施例中,参考海底电缆工厂接头和目标海底电缆工厂接头的长度无需完全相同,但是电缆线芯对于热量有传导作用,为了保证参考海底电缆工厂接头的关键区域测得的温度与目标海底电缆工厂接头一致,消除参考海底电缆工厂接头测得的温度的误差,参考海底电缆工厂接头的两端电缆部分总长度可设置为至少20m以上,且参考接头两侧电缆长度相等(均为10m以上)。
基于以上参考海底电缆工厂接头,可获取参考海底电缆工厂接头的各参考关键区域的温度测量值。这里的参考关键区域指的是参考海底电缆工厂接头中的关键区域,与目标海底电缆工厂接头中的各关键区域的位置一一对应。
示例地,获取参考海底电缆工厂接头的各参考关键区域的温度测量值可以是通过在参考海底电缆工厂接头的各参考关键区域中安装温度测量类的器件,然后通过读取温度测量类的器件测量到的温度得到参考海底电缆工厂接头的各参考关键区域的温度测量值。
S202,将各参考关键区域的温度测量值确定为目标海底电缆工厂接头中对应的测量关键区域的温度测量值。
基于上述得到的参考海底电缆工厂接头中各参考关键区域的温度测量值,直接将测得的温度值确定为目标海底电缆工厂接头中对应关键区域的温度测量值。
本申请实施例中,计算机设备通过获取参考海底电缆工厂接头的各参考关键区域的温度测量值,将各参考关键区域的温度测量值确定为目标海底电缆工厂接头中对应的测量关键区域的温度测量值。由于参考海底电缆工厂接头与目标海底电缆工厂接头的主体结构和所处环境均相同,且参考海底电缆工厂接头与目标海底电缆工厂接头之间相隔预设距离后并排放置,这样,参考海底电缆工厂接头中的 关键区域可以完全等效目标海底电缆工厂接头中的关键区域,即参考海底电缆工厂接头与目标海底电缆工厂接头中的温度分布是一致的,从而实现通过参考海底电缆工厂接头精准监测加热过程中的目标海底电缆工厂接头中各关键区域的温度。
接下来,在介绍上述温度测量系统的实现过程之前,先从结构方面对上述参考海底电缆工厂接头和目标海底电缆工厂接头的所处环境和主体结构进行说明。
基于前述描述可知,本申请实施例中的关键区域的温度测量是基于在海底电缆工厂接头制作工艺中对涉及到加热环节的精准控温,是保证目标海底电缆工厂接头绝缘高质量的重要前提。因此,在本申请实施例实施时,对参考海底电缆工厂接头和目标海底电缆工厂接头的加热方式需先进行说明。
一个实施例中,可以是基于电磁感应加热原理,采用电磁线圈直接在导体线芯产生涡流,并配合金属外加热模具,不仅能实现参考海底电缆工厂接头和目标海底电缆工厂接头的快速升温,还能够避免从电缆外部向电缆内部单向加热技术中绝缘温度不均以及加热时间过长等问题。所以本申请实施例中对参考海底电缆工厂接头和目标海底电缆工厂接头的加热是采用磁感应加热方法实现,参考海底电缆工厂接头和目标海底电缆工厂接头均包括电磁感应加热系统、金属冷却套以及金属加热模具。
在一个实施例中,如图4所示,其中,A为目标海底电缆工厂接头、B为参考海底电缆工厂接头、14为电磁线圈15为导体线芯、16为绝缘料挤塑流道口、17为硅橡胶衬垫、13为反应力锥、12为金属加热模具、11为金属冷却套。
参考海底电缆工厂接头和目标海底电缆工厂接头在两侧均对称放置电磁线圈,是为了保证参考海底电缆工厂接头和目标海底电缆工厂接头整体区域中的温度可以均匀。参考海底电缆工厂接头和目标海底电缆工厂接头无论是其结构(除长度)还是加热装置,两者均是一致的。
先对上述金属冷却套以及金属加热模具进行说明。一个实施例中,参考海底电缆工厂接头和目标海底电缆工厂接头包括相同的金属冷却套和相同的金属加热模具。金属加热模具设置于目标海底电缆工厂接头或参考海底电缆工厂接头的反应力锥外侧;金属冷却套位于金属加热模具两侧,且与金属加热模具和电缆外侧均紧密接触。
其中,金属加热模具是指安装在目标海底电缆工厂接头和参考海底电缆工厂接头的反应力锥外侧的模具,该模具可以为挤塑恢复绝缘的模具,也可以为恢复绝缘加热交联用的模具,其结构可根据实际应用中的需求来调整。
其中,金属冷却套位于金属加热模具两侧,且与金属加热模具和电缆外侧均紧密接触,是用来使金属加热模具两侧的电缆绝缘层降温,防止绝缘因温度过高而发生形变,其紧挨着金属加热模具两侧放置,采用风冷或水冷的方式使电缆绝缘层降温,这样使得参考海底电缆工厂接头和目标海底电缆工厂接头的电缆不至于因绝缘因受热而发生形变。
本实施例中,通过在目标海底电缆工厂接头和参考海底电缆工厂接头中设置金属加热模具和金属冷却套,能够使得目标海底电缆工厂接头和参考海底电缆工厂接头的挤塑模具恢复绝缘,让其形成需要的形状,并且可以使挤塑模具外侧的电缆绝缘层降温,防止其受热发生形变。
上述金属冷却套以及金属加热模具是建立在感应加热系统的需求上安装的。下面对感应加热系统进行说明。在一个实施例中,感应加热系统包括电磁线圈和感应加热电源(图4中未示意);电磁线圈设置于金属冷却套两侧,且电磁线圈与金属冷却套之间的距离大于预设距离。
电磁线圈可以是带水冷的固定线圈,也可以是可手工缠绕的电磁线,其位于金属冷却套两侧,且与金属冷却套之间存在预设距离,例如,该距离可以为大于等于5cm,这样可以防止电磁线圈产生的磁场使金属冷却套过度发热。
实际应用中,在电磁线圈通入高频大电流时,其产生磁场可以透过绝缘屏蔽和绝缘层,使电磁线圈对应处的导体线芯产生涡流并迅速升温,然后向海底电缆工厂接头处的导体线芯传递热量,使恢复导体屏蔽和反应力锥内侧升温。通过控制感应加热电源的输出电流和电功率来实现海底电缆工厂接头的线缆中线芯的升温。例如,感应加热电源输出电流的频率在1kHz~50kHz之间,该范围的频率可以使感应线圈处的导体线芯迅速升温,而且可以保证电磁线圈处的绝缘屏蔽不会在磁场作用下升温过高。又例如,感应加热电源的电功率控制在10kW以上,这样可以满足导体线芯快速升温。
本实施例中,在海底电缆工厂接头处安装感应加热系统,包括电磁线圈和感应加热电源,通过感应加热电源的输出电流和电功率使电磁线圈处的导体线芯迅速升温,之后向海底电缆工厂接头处的导体线芯传递热量,这样海底电缆工厂接头的关键区域(例如恢复导体屏蔽和反应力锥内侧)的内侧的温度就会升高,从实现海底电缆工厂接头中各关键区域的加热效果。
请参见图5所示,图5是以电压等级是110kV、铜导体线芯截面800mm
2的交联聚乙烯绝缘电力电缆参考海底电缆工厂接头为例,示意出的在预热过程中的200min时参考海底电缆工厂接头的仿真计算温度分布云图。图5为采用仿真计算的方法,获取在电流频率15kHz、有效值180A加热70min和有效值140A加热130min情况下,参考海底电缆工厂接头的温度分布云图。
由于在本申请实施例中,目标海底电缆工厂接头与参考海底电缆工厂接头采用的电磁线圈一致、并且电磁线圈中的电流幅值和频率一致,以保证电磁感应加热有相同效果。因此在实际工艺中,电磁线圈可以是采用电磁软线结构实现,且由相同的磁感应加热电源来供电。相比于传统的单独依靠金属模具外侧加热的方法需要数十小时甚至数天时间,本申请实施例中联合磁感应加热,选取适当的加热工艺,就可以迅速提高加热效率。例如,仅需不到4小时即可使海底电缆工厂接头关键区域的温度提高至110℃左右,这样,极大提高了海底电缆工厂接头关键区域的温度升温效率。
如图6所示,是以电压等级110kV、铜导体线芯截面800mm
2的交联聚乙烯绝缘电力电缆参考海底电缆工厂接头为例,示意的在预热过程中电磁线圈处导体中心①、反应力锥根部②、反应力锥内侧③、反应力锥外侧④、反应力锥中间⑤和恢复导体屏蔽中间⑥的温度随时间变化示意图。图6中,海底电缆工厂接头关键区域①-⑥的温度在100min即可稳定保持在110℃~120℃。那么在此过程中,就可以在目标海底电缆工厂接头进行恢复绝缘的挤出操作。当然,考虑到恢复绝缘的挤出温度一般在110℃~120℃,而金属加热模具腔体内几乎不存在换热过程,这样参考海底电缆工厂接头即使不进行恢复绝缘的挤出工艺,其温度仍然可以参照。
继续参见图7所示,示意的是以电压等级110kV、铜导体线芯截面800mm
2的交联聚乙烯绝缘电力电缆参考海底电缆工厂接头为例,从仿真计算中得出的导体线芯沿其电缆长度方向温度随电缆长度的变化规律的示意图,即为海底电缆工厂接头的导体线芯从海底电缆工厂接头中心处沿电缆方向的温度变化示意图。从图7可以看出,在距离中心处4m外的电缆线芯不再有温升,这说明实际应用中,对参考海底电缆工厂接头的两侧电缆总长度可以以20m长度为基准进行选取(两侧电缆长度相等,各10m),此长度是足够的可以是使得参考海底电缆工厂接头与目标海底电缆工厂接头温度在关键区域能够保持一致。
因此,在实际应用中,可以通过测量参考海底电缆工厂接头中的参考关键区域,以此来评估目标海底电缆工厂接头中对应关键区域的温度。
可选地,可以将在参考海底电缆工厂接头的关键区域设置温度测量系统以此来获取参考海底电缆工厂接头中各参考关键区域的温度。在一个实施例中,参考海底电缆工厂接头包括温度测量系统,该温度测量系统设置于参考海底电缆工厂接头中各参考关键区域中。
其中,该温度测量系统可以是在参考海底电缆工厂接头中每个参考关键区域中均设置一个,也可以是在多个参考关键区域或者全部参考关键区域对应设置一个温度测量系统,本申请实施例对此不作限定。
本申请实施例中的温度测量系统具有测量参考关键区域温度的功能。这样通过在参考海底电缆工厂接头的各关键区域处设置温度测量系统,采集各关键区域的温度,即可以得到参考海底电缆工厂接头各关键区域的温度测量值。这样,极大地提高了获取参考海底电缆工厂接头各关键区域的温度测量值的便利性。
接下来通过几个实施例对上述温度测量系统的功能和结构进行说明。
一种实施例中,温度测量系统包括温度传感器,每个参考关键区域设置一个温度传感器,各参考关键区域的温度测量值为各参考关键区域中的温度传感器采集的。
可以理解的是,本实施例中与前述对温度测量系统的说明相似,即温度传感器既可以是在每个参考关键区域均设置一个,也可以是在当前待测量的关键区域中设置一个传感器,这样,通过温度传感 器就可以采集到对应参考关键区域中的温度值。
可选地,该温度传感器可以是热电偶、热电阻和光纤等。
该温度传感器可放置于参考海底电缆工厂接头的感应线圈中心处导体线芯、恢复导体屏蔽、反应力锥表面等参考关键区域,从而可以有效监测参考海底电缆工厂接头关键区域的温度。
本实施例中,通过在参考海底电缆工厂接头的每个关键区域中设置一个温度传感器,能够对各参考关键区域的温度进行采集,有效保证了参考海底电缆工厂接头中各关键区域温度监测。
进一步地,该温度测量系统不局限于上述温度采集,还可以包括对采集到的各参考关键区域的温度测量值的显示。基于此,在一个实施例中,上述温度测量系统还包括温度显示器,通过温度显示器显示采集到的各参考关键区域的温度测量值。
本实施例中将温度传感器测量到参考海底电缆工厂接头各关键区域的温度用温度显示器将采集到的温度测量值显示出来。
例如,温度显示器可以是仪表式的,也可以是数字式时,其中数字式可以是通过液晶显示器(Liquid Crystal Display,LCD)实现,也可以是通过发光二极管(Light-Emitting Diode,LED)实现,本申请实施例对此不作限定。
本实施例中,通过在温度测量系统中加入温度显示器,可以在温度传感器采集到参考海底电缆工厂接头各关键区域的温度之后,将采集到的温度显示出来,从而可以使得用户快速且便利地掌握目标海底电缆工厂接头各关键区域的温度。
由于参考海底电缆工厂接头与目标海底电缆工厂接头采用同样的加热装置,包括金属加热模具和磁感应加热系统都是相同的,所以通过监测参考海底电缆工厂接头的温度可以实现对目标海底电缆工厂接头中关键区域的温度来调控加热的操作。如此,即使出现突发情况,例如断电、环境温度变化等,操作人员也可以有效判断目标海底电缆工厂接头关键区域的温度变化情况,以便对后续工艺进行调整。因此,可以利用参考海底电缆工厂接头与目标海底电缆工厂接头温度的一致性,间接实现目标海底电缆工厂接头的温度监测。而参考海底电缆工厂接头只要与目标海底电缆工厂接头主体结构相同,即可保证两者在关键区域温度的一致性。
所以上述参考海底电缆工厂接头中各参考关键区域中的温度测量值是用来间接等效目标海底电缆工厂接头中各关键区域的实时温度的,而目标海底电缆工厂接头中各关键区域的温度反映的是在目标海底电缆工厂接头在生产过程的加热环节中温度情况,一旦发现目标海底电缆工厂接头中各关键区域的温度未处于生产过程加热环节的温度要求,可以对各关键区域的温度进行调控的,以保证目标海底电缆工厂接头制作工艺以及后续工艺的标准性。
基于此,在一个实施例中,上述温度测量系统还可以包括温度控制器,若各参考关键区域的温度测量值未处于各关键区域的预设目标温度范围,向感应加热系统发送温度调整指令,温度调整指令用于指示感应加热系统将各测量关键区域的温度调整为对应的目标温度范围。
在参考海底电缆工厂接头各关键区域设置的温度测量系统不仅可以实现温度的监测和显示,还包含温度控制器,可以与感应加热电源联动实现温控功能。在温度测量系统测得参考海底电缆工厂接头各关键区域的温度之后,与各关键区域的预设目标温度范围进行比较,当各参考关键区域的温度测量值未处于各关键区域的预设目标温度范围,则向感应加热系统发送温度调整指令,此时感应加热系统会将各测量关键区域的温度调整为对应的目标温度范围。
可以理解的是,在本申请实施例中,参考海底电缆工厂接头和目标海底电缆工厂接头采用同一套感应加热系统,所以当发现某个参考关键区域的温度测量值未处于各关键区域的预设目标温度范围。通过指示感应加热系统可以使得目标海底电缆工厂接头中对应的关键区域的温度调整为对应的目标温度范围。
例如,参考海底电缆工厂接头中的1号到5号参考关键区域中的1号和3号关键区域的温度测量值未处于其对应的预设目标温度范围内,则此时表明目标海底电缆工厂接头中1号和3号关键区域的温度也是未处于目标温度范围内的,那么温度控制器向感应加热系统发送温度调整指令,感应加热系统就会将目标海底电缆工厂接头中1号和3号关键区域的温度调整为对应的目标温度范围。
本实施例中,通过在温度测量系统中加入温度控制器,并与感应加热电源联动,能够将不在各关键区域的预设目标温度范围的温度进行调控,让其测得的各关键区域的温度处于预设目标温度范围内,从而可以在制作海底电缆工厂接头时,合理地调控加热条件。
另外,在一个实施例中,本申请还提供一种根据参考海底电缆工厂接头得到目标海底电缆工厂接头关键区域温度的实施例,如图8所示,为根据参考海底电缆工厂接头得到目标海底电缆工厂接头关键区域温度的流程示意图。
请结合前述图4理解,图8中的目标海底电缆工厂接头是包括导体线芯、绝缘料挤塑流道口、硅橡胶衬垫、反应力锥、金属加热模具、金属冷却套,且目标海底电缆工厂接头已经完成了反应力锥成型打磨、导体线芯焊接(或压接)、导体屏蔽绕包等步骤,即将进行反应力锥预热和恢复绝缘挤出等步骤的海底电缆工厂接头,当然,也可以是已完成恢复绝缘挤出成型等步骤,即将进行恢复绝缘加热交联步骤的海底电缆工厂接头。参考海底电缆工厂接头的主体结构与目标海底电缆工厂接头一致,且与目标海底电缆工厂接头所用的感应加热系统为同一套装置,其长度为20m以上,两个海底电缆工厂接头间隔0.5m-1m并排放置以保证两根海底电缆工厂接头处于同一环境,并且相互之间不受对方电磁线圈产生的磁场影响。两者中的感应加热系统均包括电磁线圈和感应加热电源;电磁线圈设置于金属冷却套两侧,且与金属冷却套之间的距离在5cm以上。感应加热电源的输出电流频率在1kHz-50kHz之间,可以使感应线圈处的导体线芯迅速升温,而且可以保证感应线圈处的绝缘屏蔽不会在磁场作用下升温过高。电功率控制在10kW以上,可以满足导体线芯快速升温;温度测量系统包括温度传感器、温度显示器和温度控制器。
这样,当电磁线圈通入高频大电流时,其产生磁场可以透过绝缘屏蔽和绝缘层,使电磁线圈对应处的导体线芯产生涡流并迅速升温,然后向海底电缆工厂接头处的导体线芯传递热量,使恢复导体屏蔽和反应力锥内侧升温。温度传感器放置于参考海底电缆工厂接头的感应线圈中心处导体线芯、恢复导体屏蔽、反应力锥表面的关键区域,对各参考关键区域的温度进行采集,采集的温度可以通过温度显示器显示出来。温度控制器与感应加热电源联动,在测得参考海底电缆工厂接头各关键区域的温度之后,与各关键区域的预设目标温度范围进行比较,若各参考关键区域的温度测量值未处于各关键区域的预设目标温度范围,则向感应加热系统发送温度调整指令,温度控制器会将各测量关键区域的温度调整为对应的目标温度范围;此时采集到的参考海底电缆工厂接头各关键区域的温度即确定为目标海底电缆工厂接头的温度。
本实施例中,由于参考海底电缆工厂接头主体结构上与目标海底电缆工厂接头一致,采用的金属加热模具也相同,并且与目标海底电缆工厂接头所用的感应加热系统为同一套装置。这样当参考海底电缆工厂接头的电缆长度为20m以上时,其关键区域的温度与目标海底电缆工厂接头是一致的,温度传感器可以放置于参考海底电缆工厂接头关键区域,通过测量其温度就可以检测目标海底电缆工厂接头的温度情况,并在合理调控加热条件。利用参考海底电缆工厂接头与目标海底电缆工厂接头温度分布一致的特点,即可在保证目标海底电缆工厂接头完整性和纯净度的基础上,对目标海底电缆工厂接头关键区域进行温度监测,最终实现目标海底电缆工厂接头在加热过程中关键区域温度的精准监测。
应该理解的是,虽然如上所述的各实施例所涉及的流程图中的各个步骤按照箭头的指示依次显示,但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明,这些步骤的执行并没有严格的顺序限制,这些步骤可以以其它的顺序执行。而且,如上所述的各实施例所涉及的流程图中的至少一部分步骤可以包括多个步骤或者多个阶段,这些步骤或者阶段并不必然是在同一时刻执行完成,而是可以在不同的时刻执行,这些步骤或者阶段的执行顺序也不必然是依次进行,而是可以与其它步骤或者其它步骤中的步骤或者阶段的至少一部分轮流或者交替地执行。
基于同样的发明构思,本申请实施例还提供了一种用于实现上述所涉及的海底电缆工厂接头温度测量方法的海底电缆工厂接头温度测量装置。该装置所提供的解决问题的实现方案与上述方法中所记载的实现方案相似,故下面所提供的一个或多个海底电缆工厂接头温度测量装置实施例中的限定可以参见上文中对于海底电缆工厂接头温度测量方法的限定,在此不再赘述。
