Description
技术领域technical field

Moreover, the withstand voltage test on the cable requires the cable joint to be placed in the insulation compartment of the GIS equipment, and then the cable is pressurized to perform the withstand voltage test.
现有技术中，对电缆进行耐压测试的方法是，将电缆安装在GIS设备上，并且在GIS设备上安装测试套管，通过高压引线对GIS设备及电缆以电缆的耐压标准进行交流耐压试验。可以看出，电缆的耐压测试加压时间明显长于GIS设备的耐压测试加压时间，这样会对GIS设备的部件长时间处于高电压状态，会对GIS设备造成损伤。并且，对于不具备安装实验套管的条件的GIS设备，则无法对电缆进行交流耐压测试。In the prior art, the method for carrying out the withstand voltage test on the cable is to install the cable on the GIS equipment, and install the test sleeve on the GIS equipment, and conduct AC withstand test on the GIS equipment and the cable by the cable withstand voltage standard through the high-voltage lead wire. pressure test.

Moreover, for GIS equipment that does not have the conditions to install the experimental bushing, the AC withstand voltage test cannot be performed on the cable.

根据本发明的第一个方面，提供了一种用于电缆耐压测试的接线装置，如图1所示，该接线装置包括：壳体10，壳体10包括第一连接部11和用于连接待测试电缆的第二连接部12，壳体10的内部形成腔体13；触头部20，触头部20的至少一部分设置在腔体13内，触头部20通过第一连接部11与壳体10连接；引线部30，引线部30设置在腔体13的外部，引线部30与触头部20连接；用于向腔体13内充入绝缘气体的气阀14，气阀14设置在壳体10上。According to a first aspect of the present invention, there is provided a wiring device for cable withstand voltage testing, as shown in Figure 1, the wiring device includes: a housing 10, the housing 10 includes a first connecting portion 11 and a Connect the second connection part 12 of the cable to be tested, and the inside of the housing 10 forms a cavity 13; the contact part 20, at least a part of the contact part 20 is arranged in the cavity 13, and the contact part 20 passes through the first connection part 11 Connected to the housing 10; the lead part 30, the lead part 30 is arranged outside the cavity 13, and the lead part 30 is connected to the contact part 20; the gas valve 14 for filling the cavity 13 with insulating gas, the gas valve 14 set on the housing 10.
如图1所示，待测试电缆的电缆终端40设置在接线装置的腔体13内，腔体13内充有与GIS设备中同样的绝缘气体，这样就模拟了电缆终端40安装在GIS设备上的工作环境。因此，可以通过接线装置对待测电缆进行耐压测试，而不必将待测电缆安装在GIS设备上再进行测试，这样就避免了待测电缆的耐压测试对GIS设备造成损伤。As shown in Figure 1, the cable terminal 40 of the cable to be tested is arranged in the cavity 13 of the wiring device, and the cavity 13 is filled with the same insulating gas as in the GIS equipment, so that it is simulated that the cable terminal 40 is installed on the GIS equipment working environment. Therefore, the withstand voltage test of the cable to be tested can be carried out through the wiring device without installing the cable to be tested on the GIS equipment for testing, thus avoiding damage to the GIS equipment caused by the withstand voltage test of the cable to be tested.
优选地，第一连接部11是第一法兰，第二连接部12是第二法兰。第一法兰与设置在触头部20上的第三法兰连接，第二法兰与设置在待测电缆的电缆终端上的第四法兰连接。Preferably, the first connection part 11 is a first flange, and the second connection part 12 is a second flange. The first flange is connected with the third flange arranged on the contact part 20, and the second flange is connected with the fourth flange arranged on the cable terminal of the cable to be tested.
优选地，绝缘气体是六氟化硫。六氟化硫气体即是GIS设备中充入的绝缘气体，具有良好的绝缘性能。同时，腔体13中充有六氟化硫气体，还可以保证对待测电缆进行耐压时，电缆不对壳体10放电。Preferably, the insulating gas is sulfur hexafluoride. Sulfur hexafluoride gas is the insulating gas filled in GIS equipment, which has good insulating properties. At the same time, the cavity 13 is filled with sulfur hexafluoride gas, which can also ensure that the cable does not discharge to the casing 10 when the cable to be tested is withstand voltage.
优选地，如图2所示，触头部20包括触头机构21和电极22，电极22的第一端与第一连接部11连接，触头机构21包括：触头套211，触头套211套设在电极22的第二端，触头套211和电极22的第二端之间形成限位腔215；动触头212，动触头212设置在限位腔215内，动触头212与电极22电连接；弹性元件213，弹性元件213设置在限位腔215中，弹性元件213的一端与动触头212连接，弹性元件213的另一端与电极22连接。优选地，触头机构21还包括导流线214，电极22通过导流线214与动触头212电连接。Preferably, as shown in FIG. 2 , the contact part 20 includes a contact mechanism 21 and an electrode 22, the first end of the electrode 22 is connected to the first connection part 11, and the contact mechanism 21 includes: a contact cover 211, a contact cover 211 is sleeved on the second end of the electrode 22, and a limiting cavity 215 is formed between the contact sleeve 211 and the second end of the electrode 22; the movable contact 212, the movable contact 212 is arranged in the limiting cavity 215, and the movable contact 212 is electrically connected to the electrode 22; elastic element 213, the elastic element 213 is set in the limiting cavity 215, one end of the elastic element 213 is connected to the movable contact 212, and the other end of the elastic element 213 is connected to the electrode 22. Preferably, the contact mechanism 21 further includes a guide wire 214 through which the electrode 22 is electrically connected to the movable contact 212 .
如图2所示，当待测电缆安装在接线装置的腔体13内时，电缆终端40与动触头212接触并导通，同时，电缆终端40需要压缩压缩弹性元件213一端距离。这样，弹性元件213产生弹力，保证了电缆终端40能够与动触头212贴紧，并保证了电缆终端40与动触头212的导通。此外，电极22与动触头212之间还通过导流线214电连接，从而进一步保证了电极22与动触头212的导通。As shown in FIG. 2 , when the cable to be tested is installed in the cavity 13 of the wiring device, the cable terminal 40 is in contact with the movable contact 212 and conducts conduction. At the same time, the cable terminal 40 needs to compress the distance from one end of the elastic element 213 . In this way, the elastic element 213 generates elastic force, which ensures that the cable terminal 40 can be tightly attached to the moving contact 212 and ensures the conduction between the cable terminal 40 and the moving contact 212 . In addition, the electrode 22 and the movable contact 212 are electrically connected through the conductive wire 214 , thereby further ensuring the conduction between the electrode 22 and the movable contact 212 .
优选地，壳体10还包括第一密封垫111，触头部20通过第一密封垫111与第一连接部11连接。优选地，如图1所示，第二连接部12与待测电缆之间还设置有第二密封垫121。第一密封垫111和第二密封垫121可以保证腔体13的气密性，防止绝缘气体泄露导致电缆测试环境的变化，进而导致对电缆的耐压测试不准确。Preferably, the housing 10 further includes a first gasket 111 , and the contact part 20 is connected to the first connection part 11 through the first gasket 111 . Preferably, as shown in FIG. 1 , a second sealing gasket 121 is also provided between the second connecting portion 12 and the cable to be tested. The first gasket 111 and the second gasket 121 can ensure the airtightness of the cavity 13 and prevent the cable test environment from changing due to the leakage of the insulating gas, thereby causing inaccurate withstand voltage tests on the cable.
优选地，接线装置还包括绝缘套31，绝缘套31套设在引线部30上。Preferably, the wiring device further includes an insulating sheath 31 , and the insulating sheath 31 is sleeved on the lead part 30 .
优选地，引线部30与触头部20相互垂直设置。这样，接线装置呈L形，便于在引线部30处连接测试引线，也能减小接线装置的水平长度，节省空间。Preferably, the lead part 30 and the contact part 20 are vertically arranged. In this way, the wiring device is L-shaped, which is convenient for connecting test leads at the lead part 30, and can also reduce the horizontal length of the wiring device, saving space.
根据本发明的第二个方面，提供了一种电缆耐压测试方法，首先，提供上述的接线装置；其次，将待测试电缆的电缆终端40插入接线装置的壳体10的腔体13内，并将待测试电缆的电缆终端40与壳体10的第二连接部12连接；之后，将接线装置的引线部30与耐压测试设备电连接；然后，通过接线装置的气阀14将腔体13内的空气抽出，并向腔体13内充入绝缘气体；最后，使用耐压测试设备对待测试电缆进行耐压测试。According to a second aspect of the present invention, a cable withstand voltage testing method is provided. First, the above-mentioned connection device is provided; secondly, the cable terminal 40 of the cable to be tested is inserted into the cavity 13 of the housing 10 of the connection device, And the cable terminal 40 of the cable to be tested is connected to the second connection part 12 of the housing 10; after that, the lead wire part 30 of the wiring device is electrically connected to the withstand voltage testing equipment; The air in the cavity 13 is drawn out, and an insulating gas is filled into the cavity 13; finally, a withstand voltage test is performed on the cable to be tested by using a withstand voltage test device.
此电缆耐压测试方法是将待测电缆与接线装置连接，模拟待测电缆安装在GIS设备中的工作环境，再对待测电缆进行耐压测试。而不是像现有技术中那样将待测电缆安装在GIS设备中，再进行耐压测试。所以，此电缆耐压测试方法不会对GIS设备造成损伤，同时又能保证测试结果的准确性与可靠性。The cable withstand voltage test method is to connect the cable to be tested with the wiring device, simulate the working environment of the cable to be tested installed in the GIS equipment, and then perform the withstand voltage test on the cable to be tested. Instead of installing the cable to be tested in the GIS equipment as in the prior art, the withstand voltage test is then performed. Therefore, this cable withstand voltage test method will not cause damage to the GIS equipment, and at the same time can ensure the accuracy and reliability of the test results.
优选地，若待测电缆的电缆终端为短型的电缆终端，即长度为470mm的电缆终端，当将此种短型的电缆终端安装入接线装置的腔体13中时，在电缆终端和动触头212之间设置加长导体，保证电缆与触头部20之间能够导通。Preferably, if the cable terminal of the cable to be tested is a short cable terminal, that is, a cable terminal with a length of 470mm, when this short cable terminal is installed in the cavity 13 of the wiring device, the cable terminal and the moving An extended conductor is arranged between the contacts 212 to ensure the conduction between the cable and the contact part 20 .
