如何实现对高低压成套电气产品的质量控制

How to realize the quality control of high and low voltage complete sets of electrical products

通常情况下，高压成套电气产品主要是指额定工作电压在三千伏到三十五千伏之内的开关柜，比如说KYN61-40.5、XGN-40.5以及XGN15-12等。而低压成套电气产品则是指交流额定工作电压处于六百伏的开关柜，常见的有GCK(L)、GCS、MNS、MCC、AR以及PZ30等。在我国现阶段中，高压成套电气产品的结构设计中应用较多的先进技术，比如说SF6技术、真空技术以及组合技术等，在生产过程中运用涉及到的壳体生产线、焊接机器人、机械加工中心、柜体加工用数控以及真空环氧浇注及注塑设备等也是比较先进的生产设备，目前我国的电压在五百伏以下的高压成套电气设备已经达到国家先进水平。而对于低压成套电气产品来说，我国技术水平的不断提升带动了智能化、可通信特征在低压成套电气设备的生产中得到推广使用，低压成套电气产品的智能化以及可通信特征决定了其将逐渐成为高档产品。

Usually, the high voltage complete electrical products mainly refer to the switching cabinet with rated operating voltage from three thousand volts to 3. 5 kilovolts, such as KYN61-40.5, XGN-40.5, and XGN15-12. The low voltage complete electrical products refer to the switchgear with AC rated working voltage at six hundred volts, and commonly have GCK (L), GCS, MNS, MCC, AR and PZ30. In the present stage of our country, many advanced technologies are used in the structural design of high voltage complete electrical products, such as SF6 technology, vacuum technology and combination technology. In the process of production, the shell production line, welding robot, machining center, CNC machine tool and vacuum epoxy pouring and injection are used in the production process. Plastic equipment is also a relatively advanced production equipment. At present, China's high-voltage electrical equipment with a voltage below five hundred volts has reached the advanced level of the country. For the low voltage complete sets of electrical products, the continuous improvement of the technical level in China has led to the popularization of intelligent and communicable features in the production of low voltage complete sets of electrical equipment. The intelligentized and communicable features of the low voltage complete sets of electrical products decide that they will gradually become high grade products.

1.加强对高低压成套电气产品原材料的控制

1., strengthen the control of raw materials for high-voltage and low-voltage electrical products.

通过对高低压成套电气产品的加工过程中及加工工艺研究我们不难发现，制作外壳是加工高低压成套电气产品的第一步，现阶段加工外壳时主要使用钢板，市场上常用的钢板有冷热轧板、镀锌板以及雪花板等多种种类和型号，钢板的厚度也各有不同。一般来讲，成套的高压设备在进行外壳生产时一般选择使用厚度为两毫米的镀锌板，而成套的低压设备在进行外壳的生产时一般选择使用大生产商生产的武钢、宝钢等的冷轧板。其次，在对高低压成套电气产品的绝缘材料进行控制时必须加强对材料阻燃性以及耐压性的检验，确保绝缘材料具有较大的绝缘性能，为了有效的降低空气潮湿对材料绝缘性能带来的影响可以选择在绝缘材料的表面涂刷绝缘漆。最后，作为影响高低压成套电气产品温升性能的最主要参数，铜母线强度和电阻效率的控制显得尤为重要，铜母线中铜的含量以及加工效能不当容易导致整个铜母线的载流量发生变化，使整个高低压成套电气设备难以正常工作，因此，在进行高低压成套电气产品的加工时应该加强对铜母线的质量控制，保证铜排表面在弯曲后没有裂纹以及褶皱现象。

It is not difficult to find that the processing process and processing technology of the high and low voltage complete electrical products are not difficult to find. The manufacture of the shell is the first step to process the high and low voltage complete sets of electrical products. At the present stage, the steel plate is mainly used when the shell is processed. The common steel plate in the market has many kinds and types, such as cold hot rolled plate, galvanized sheet and snowflake. The thickness of the steel plate is also different. Generally speaking, a complete set of high voltage equipment usually chooses galvanized sheet with a thickness of two millimeters in the case of shell production, while a complete set of low-voltage equipment generally chooses cold rolled plates, such as Wugang and Baosteel, which are produced by big producers in the production of the shell. Secondly, it is necessary to strengthen the test of the material flame retardancy and pressure resistance when controlling the insulation material of the high and low voltage complete electrical products, so as to ensure that the insulating material has greater insulation property. In order to effectively reduce the influence of air humidity on the insulation property of the material, the insulating varnish can be selected on the surface of the insulating material. . At last, as the most important parameter that affects the temperature rise performance of the high and low voltage complete electrical products, the control of the strength of copper busbar and the resistance efficiency is particularly important. The copper content in the copper busbar and the improper processing efficiency can easily lead to the change of the load of the whole copper busbar, which makes it difficult for the whole high and low voltage complete electrical equipment to work normally. Therefore, the quality control of copper busbar should be strengthened during the processing of high and low voltage complete electrical products, so as to ensure that there is no crack and wrinkle on the surface of the copper row after bending.

2.加强对高低压成套电气产品加工设备及加工工艺的控制

2., strengthen the control of high and low voltage complete sets of electrical products processing equipment and processing technology.

对高低压成套电气设备的加工设备及加工工艺进行控制是提高其质量控制的一个关键环节。一般高低压成套电气设备加工结构中有剪板机、冲床以及数控折弯机三种设备，其中，剪板机主要用来对钢板的修剪，冲床用来对修剪后的剪板进行冲孔处理，而数控折弯机则是用来将冲孔后的钢板进行折弯处理，剪板机、冲床以及数控折弯机三种设备在使用的过程中都需要根据相应的操作技术规范进行使用，钢板的加工与制造应按照高低压成套电气设备的实际要求进行。在对壳体加工工艺进行控制时需要对各道工序进行控制，严格控制每道工序中存在的误差，将其控制在一个合理的范围之内，最大程度的提高高低压成套电气设备外壳的质量。对于高低压成套电气产品而言，其外壳的制造一般要求整齐、有序，保持门缝之间的均匀一致。最后，高低压成套电气设备的各个组成部件加工完毕后还要对其装配加工工艺进行质量控制，在装配的过程中需要对装配元器配件、铜排、一次大线以及二次控制线进行控制，严格根据装配要求进行制作和装配。对于固定式的成套产品而言，一般需要设置相应的盘面，在设置的过程中既要考虑相关的技术要求，同时也应该保证高低压成套电气设备的整体性以及美观性。

Controlling the processing equipment and processing technology of high and low voltage complete sets of electrical equipment is a key step to improve its quality control. In general, there are three kinds of equipment in the processing structure of high and low voltage complete electrical equipment. The cutting machine, punch press and CNC bending machine are used. Among them, the shearing machine is mainly used to trim the steel plate. The punch press is used for punching the clipboard after cutting, while the CNC bending machine is used to bend the steel plate after the punching, the cutting machine and the punching machine. The three kinds of equipment in the bed and the CNC bending machine need to be used according to the corresponding technical specifications. The processing and manufacturing of the steel plate should be carried out according to the actual requirements of the high and low voltage complete sets of electrical equipment. In controlling the processing technology of the shell, it is necessary to control each process, strictly control the error in each process, control it in a reasonable range, and improve the quality of the shell of the high and low voltage complete electrical equipment to the maximum extent. For high and low voltage complete electrical products, the manufacturing of its outer shell is generally ordered and orderly, and the uniformity of the seam is kept. Finally, the assembly and processing technology of the high and low voltage complete electrical equipment must be controlled. In the process of assembly, it is necessary to control the assembly, copper, a large line and two control lines, and make and assemble the assembly strictly according to the assembly requirements. For the fixed set of products, it is generally necessary to set up the corresponding plate. In the process of setting up, we should not only consider the relevant technical requirements, but also ensure the integrity and beauty of the high and low voltage complete sets of electrical equipment.

3.加强对高低压成套电气产品的检验与试验

3. strengthen the inspection and test of high and low voltage complete sets of electrical products.

对高低压成套电电气产品进行检验和试验对进一步提高高低压成套电气产品的质量有着较大的促进作用，这也是高低压成套电气产品生产过程中最后的一个环节，对高低压成套电气产品进行检验和试验是一项比较复杂的过程，在检验和试验的过程中应该严格按照规定的顺序进行，高低压成套电气产品中的结构件需要进行喷塑以及电镀处理，加强对这两个环节的检验能够确保成套设备的整体性与美观性。对铜排进行检验时需要检验其选型是否符合技术要求，并且还要检验其制作过程中是否存在偏差，是否有锤痕、压痕等现象的存在。最后，由于许多的高低压成套电气产品中都存在机械连锁，加强对机械连锁的检验有助于确保机械连锁的稳定性，将安全事故的发

Testing and testing high and low voltage electrical and electrical products has a great effect on further improving the quality of high and low voltage complete electrical products. It is also the last link in the production process of high and low voltage complete electrical products. It is a complicated process to test and test the high and low voltage complete electrical products. In the process of testing and testing, it should be carried out in strict order. The structure parts of the high and low voltage complete electrical products need to be sprayed and electroplated. To strengthen the inspection of these two links can ensure the integrity and beauty of the complete set of equipment. It is necessary to test whether the type of copper row is in accordance with the technical requirements, and whether there is a deviation in the process of production, and whether there is a phenomenon of hammer marks and indentation. Finally, because of the mechanical chain in many high and low voltage electrical products, the strengthening of the mechanical linkage test will help to ensure the stability of the mechanical chain and the safety of the accidents.
