RTGM高压封闭母线特性 Characteristics of RTKMCG High Voltage Common Box Busbar

简洁的设计 Concise Design

RTGM 共箱母线两侧为散热器式的铝镁合金型材，厚度达到5.5mm，由于散热条亦可增强侧板刚性强度，因此两侧高度可达到305mm 高度亦可无须任何加强措施。上下封板采用敷铝锌板，亦是保证组装成型后母线整体的结构强度。侧板与底板采用高强度铆钉铆紧。盖板与两侧板则用螺栓连接。每节母线一般在上部都有合理的设有标准检修孔（也可根据现场需求侧面设置），检修口处的制作工艺和高要求的伸缩节连接技术，使母线外壳防护等级高达IP54。在通常户外环境下安装无需调整防护等级。

The two sides of the RTKMCG common box busbar are radiator type aluminum magnesium alloy profiles with a thickness of 5.5mm. As the heat dissipation strip can also enhance the rigidity and strength of the side plate, the height on both sides can reach 305mm without any reinforcement measures. The upper and lower sealing plates are made of aluminum zinc coated plates to ensure the overall structural strength of the assembled busbar. The side panel and bottom panel are fastened with high-strength imported rivets. The cover plate and the two side plates are connected by bolts. Each section of the busbar generally has a reasonable standard maintenance hole at the upper part (which can also be set on the side according to on-site needs), and the unique manufacturing process and high requirement expansion joint connection technology at the maintenance hole make the busbar shell protection level up to IP54. Installation in typical outdoor environments does not require adjusting the protection level.

短路强度 Short Circuit Strength

由于其设计的高强度外壳及合理的母排水平放置，使HYTKMCG 电汇排可承受5 万安短路带来的冲击。

Due to its high-strength shell design and reasonable horizontal placement of the busbar, the HYTKMCG busbar can withstand the impact of a 50000 ampere short circuit.

磁场 Magnetic Field

经独立的实验室测试证实，RTKMCG 共箱母线所产生的磁场是微不足道的。

Independent laboratory tests have confirmed that the magnetic field generated by the RTKMCG common box busbar is negligible.

低噪音 Low Noise

由于在设计上，导体与绝缘子与外壳紧密固定，由于两侧用铝镁合金材料，隔断磁环流产生，故此通电后可大大减少噪音的产生。

Due to the tight fixation of the conductor, insulator, and casing in the design, and the use of aluminum magnesium alloy materials on both sides to block the magnetic ring flow, the generation of noise can be greatly reduced after power on.

弹性的设计 Elastic Design

RTKMCG 共箱母线外壳由铝镁合金材料制成，可应客户的需求造出特别的设计元件，如30 度弯、45 度弯、90 度弯、135 度弯，这些弯件可以是水平的，亦可以是垂直的。

The RTKMCG common box busbar shell is made of aluminum magnesium alloy material and can be customized with special design components according to customer needs, such as 30 degree bends, 45 degree bends, 90 degree bends, and 135 degree bends. These bends can be horizontal or vertical.

外壳为地线 The Shell is a Ground Wire

根据电气技术委员会(IEC）公布及提倡母线的外壳作为接地导体。因此，HYTKMCG 母线外壳是采用铝镁合金材料制造，比铁片造外壳的地线更为有效，加上外壳上的散热片设计，使接地导体的有效面积比相线电流高三倍以上。

According to the International Electrotechnical Commission (IEC), it is recommended to use the outer shell of the busbar as a grounding conductor. Therefore, the HYTKMCG busbar housing is made of aluminum magnesium alloy material, which is more effective than the grounding wire made of iron sheets. In addition, the unique heat sink design on the housing makes the effective area of the grounding conductor more than three times higher than the phase line current.

加热装置 Heating Device

在母线槽的两侧，每2M 母线HYTKMCG 母线均加添了加热器，以便于母线在长时间不用时，槽体内可能产生的凝露的清除。

On both sides of the busbar trunking, heaters are added to every 2M busbar HYTKMCG busbar to facilitate the removal of condensation that may occur inside the trunking body when the busbar is not in use for a long time.

集水槽及自动放水功能 Collecting Tank and Automatic Drainage Function

精致的制作工艺和合理的结构使母线制后，表面精致大方，达到户外户内无积水要求。在必要的母线底板上有集水槽，在集水槽的端部设有集水自动弃放装置。既能有效地弃放母线内部积水，又能阻挡灰尘及异物的进入。

The exquisite production process and reasonable structure make the surface of the busbar exquisite and generous, achieving the requirement of no water accumulation indoors and outdoors. There is a water collection tank on the necessary busbar base plate, and an automatic water collection and disposal device is installed at the end of the water collection tank. It can effectively dispose of accumulated water inside the busbar and block the entry of dust and foreign objects.

长寿命 Long Lifespan

1、外壳两侧为经过阳氧化处理的铝镁合金材料，上下盖板均为采用敷铝锌板材料，保证了外壳的耐腐、耐酸碱环境使用。

2、绝缘子采用高强绝缘材料真空浇注，保证了其绝缘及刚性强度。

3、导体采用整条镀银，保证了温升要求，又保证了导体表面长时间与空气接触后，可能产生的铜绿, 并且应客户的要求可以

将整段导体用热缩套管包裹。

4、良好的散热材料及加大了的散热面积，保证了母线温升在设计的范围内。

1. The two sides of the shell are made of anodized aluminum magnesium alloy material, and the upper and lower cover plates are made of imported aluminum zinc coated plate material, ensuring the corrosion resistance and acid alkali resistance of the shell for use in an environment.

2. The insulator is made of imported high-strength insulation material vacuum cast, ensuring its insulation and rigidity strength.

3. The entire conductor is silver plated to ensure temperature rise requirements and to prevent the formation of copper green on the surface of the conductor after prolonged contact with air. Additionally, the entire conductor can be wrapped in heat shrink tubing upon special request from the customer.

4. Good heat dissipation materials and increased heat dissipation area ensure that the temperature rise of the busbar is within the designed range.

伸缩节 Telescopic Joint

RTKMCG 共箱母线在总体直线长度超过40M，或者是穿越建筑结构中的伸缩缝，采用伸缩节，它主要是实现水平、垂直方向两个自由度的调节，不仅能满足不同温降及热胀冷缩引起的伸缩要求。还可以对基础沉降所引起的误差进行补偿。其的伸缩节设计，使较大的母线箱体能够灵活拼接，从而使母线系统的设计、安装能够达到程序化、标准化。

The RTKMCG common box busbar adopts expansion joints when the overall straight length exceeds 40M, or when passing through expansion joints in building structures. It mainly realizes the adjustment of two degrees of freedom in the horizontal and vertical directions, which can not only meet the expansion and contraction requirements caused by different temperature drops and thermal expansion and contraction. It is also possible to compensate for errors caused by foundation settlement. Its special expansion joint design enables flexible splicing of larger busbar boxes, thereby achieving programmatic and standardized design and installation of busbar systems.

减震措施 Shock Absorption Measures

为了解决变压器、发电机及配电柜运行时产生的震动对封闭母线的负面影响，在与封闭母线连接处采用软连接，外壳之间加入橡胶垫来减小震动，对于封闭母线本体，在系统中加装减震器，对高压绝缘子和导电排实现弹性支持，较好地避免了外壳产生的机械及地震波给封闭母线带来的破坏。

In order to address the negative impact of vibration generated during the operation of transformers, generators, and distribution cabinets on enclosed busbars, a soft connection is used at the connection with the enclosed busbar, and rubber pads are added between the shells to reduce vibration. For the enclosed busbar body, shock absorbers are installed in the system to provide elastic support for high-voltage insulators and conductive bars, effectively avoiding damage to the enclosed busbar caused by mechanical and seismic waves generated by the shells.

安装容易 Easy to Install

连接位的简单构造及制造上的高精度安装变得容易，在紧密空间内的应用显得更加重要。

The simple construction of connection positions and high-precision installation in manufacturing have become easier, making their application in tight spaces even more important.

节省保养 Save Maintenance
