Abstract
Description
一、技术领域1. Technical field
本发明涉及电力技术领域，具体涉及一种35kV及110kV变压器例行试验接线转换箱。The invention relates to the field of electric power technology, in particular to a routine test wiring conversion box for 35kV and 110kV transformers.
二、背景技术2. Background technology
长期高负荷运行的变压器容易发生故障，常见的变压器故障有内部绝缘老化，绕组匝间短路等。国家电网公司企业标准Q/GDW1168-2013《输变电设备状态检修试验规程》规定对110kV及35kV的变压器需要定期进行的高压试验。在对变压器进行高压试验时需要将试验仪器的引线连接在变压器各侧的套管桩头上，根据不同的试验项目，改变其各侧套管桩头的连接方式。目前，传统的试验方法是在变压器上用试验线进行各侧绕组接线方式的改变，每进行一项试验就需要爬一次主变进行接线方式的改变，因此我们研制了变压器例行试验接线转换箱。Transformers that operate under high load for a long time are prone to failures. Common transformer failures include aging of internal insulation and inter-turn short circuit of windings. State Grid Corporation of China Enterprise Standard Q/GDW1168-2013 "Test Regulations for Condition Maintenance of Power Transmission and Transformation Equipment" stipulates that 110kV and 35kV transformers need to be regularly tested for high voltage. When carrying out high-voltage tests on transformers, it is necessary to connect the lead wires of the test instrument to the bushing pile heads on each side of the transformer, and change the connection mode of the bushing pile heads on each side according to different test items. At present, the traditional test method is to use the test line on the transformer to change the wiring mode of each side winding. Every time a test is carried out, it is necessary to climb the main transformer to change the wiring mode. Therefore, we have developed a transformer routine test wiring conversion box. .
三、发明内容3. Contents of the invention

所述转换箱（1）由绝缘材料制成。The conversion box (1) is made of insulating material.
所述转换箱（1）由树脂材料制成。The conversion box (1) is made of resin material.
本发明的使用方法为：将试验接线转换箱顶部A组（2）、B组（3）、C组（4）、D组（5）、E组（6）五组接线头分别与变压器上的高压、中压、低压接线头连接，B组（3）、C组（4）、D组（5）、E组（6）第一个接线头与变压器上的高压连接，B组（3）、C组（4）、D组（5）、E组（6）中间接线头与变压器上的中压连接，B组（3）、C组（4）、D组（5）、E组（6）第三个接线头与变压器上的低压连接，在试验高压时，将转换箱（1）侧面上对应的中压和低压短路，便可以进行试验，在试验中压时，将转换箱（1）侧面上对应的高压和低压短路，在试验低压时，将转换箱（1）侧面上对应的中压和高压短路，本试验中操作人员不需要再频繁爬电线杆接线短路，减少劳动强度。The method of use of the present invention is as follows: connect the five groups of wiring heads of group A (2), group B (3), group C (4), group D (5) and group E (6) on the top of the test wiring conversion box to the transformer respectively. The high-voltage, medium-voltage and low-voltage terminals are connected, the first terminal of group B (3), group C (4), group D (5), and group E (6) is connected to the high voltage on the transformer, group B (3 ), Group C (4), Group D (5), Group E (6) The intermediate terminal is connected to the medium voltage on the transformer, Group B (3), Group C (4), Group D (5), Group E (6) The third terminal is connected to the low voltage on the transformer. When testing the high voltage, short-circuit the corresponding medium voltage and low voltage on the side of the conversion box (1), and the test can be carried out. When testing the medium voltage, connect the conversion box (1) The corresponding high voltage and low voltage on the side are short-circuited. When testing the low voltage, the corresponding medium voltage and high voltage on the side of the conversion box (1) are short-circuited. In this test, the operator does not need to frequently climb the pole to connect the short circuit, reducing labor strength.
本发明的有益效果在于：The beneficial effects of the present invention are:
减少攀登主变的次数。Reduce the number of times to climb the main transformation.
变压器高压例行试验主要有：绕组直流电阻、铁芯夹件绝缘电阻、各侧绕组电阻、绕组绝缘介质损耗因数及电容量、有载分接开关检查、绕组变形。对于110kV三绕组变压器各项试验攀登变压器次数统计，共计12次。而使用该接线箱后，只需要攀登2次就能完成变压器高压例行试验项目。Transformer high-voltage routine tests mainly include: winding DC resistance, iron core clamp insulation resistance, winding resistance on each side, winding insulation dielectric loss factor and capacitance, on-load tap changer inspection, and winding deformation. For the 110kV three-winding transformer, there are 12 times in total to climb the transformer for various tests. After using the junction box, it only needs to climb twice to complete the transformer high-voltage routine test project.
减少在变压器上工作的时间。Reduce time spent working on transformers.
在进行变压器高压例行试验时，传统的试验方法是将试验仪器的试验线连接到变压器对应的各侧套管桩头上，同时根据每个试验项目的要求用短接线改变其他绕组的接线方式，各项试验完成后，拆除试验引线和短接线，再进行下一项试验项目。以上所有的工作，试验人员都是在变压器上进行。而使用该箱后，只需要登上变压器将该转换箱的试验引线连接到变压器各侧套管桩头处，试验时在地面上将试验仪器的试验引线连接到该转换箱上，并在该转换箱上改变各侧的接线方式，大大减少了在变压器上工作的时间。When performing routine high-voltage transformer tests, the traditional test method is to connect the test line of the test instrument to the bushing pile head on each side of the transformer, and at the same time change the wiring mode of other windings with short wires according to the requirements of each test item. , After each test is completed, remove the test lead and short wire, and then proceed to the next test item. All the above work, the test personnel are carried out on the transformer. After using the box, it is only necessary to mount the transformer and connect the test leads of the conversion box to the bushing pile heads on each side of the transformer. During the test, connect the test leads of the test instrument to the conversion box on the ground, and Change the wiring mode of each side on the conversion box, which greatly reduces the working time on the transformer.
提高工作效率和安全性。Improve work efficiency and safety.
传统的试验方法接线都是在变压器上进行的，而变压器较高，变压器顶部结构复杂，试验人员移动困难，高压套管桩头很高，试验人员接线困难，同时给试验工作带来较大的危险性。使用该转换箱后，将变压器顶部危险的工作，转移到地面来做，提高了工作效率，降低了工作的危险性。The traditional test method wiring is carried out on the transformer, but the transformer is high, the structure of the top of the transformer is complicated, it is difficult for the test personnel to move, the pile head of the high-voltage bushing is very high, the test personnel are difficult to connect, and at the same time, it brings great difficulties to the test work. dangerous. After using the conversion box, the dangerous work on the top of the transformer is transferred to the ground, which improves the work efficiency and reduces the danger of the work.
该转换箱性能稳定，满足试验技术要求，变压器例行试验的所有试验项目改变接线方式的工作都在地面上进行，工作人员不需要安全带，同时也没有安全带的束缚，解决了夜间在变压器顶部抢修工作的危险，提高了试验人员的工作效率，主变高压试验工作由原来的五人，减少为三人。The conversion box has stable performance and meets the technical requirements of the test. The work of changing the wiring mode of all test items in the routine test of the transformer is carried out on the ground. The danger of top repair work has improved the work efficiency of the test personnel, and the high-voltage test work of the main transformer has been reduced from the original five to three.
