母线槽的极限温升值是指，母线槽通过额定电流满负荷运行时，稳定下来的高温度减去环境温度得到的温升值，通常用K来表示。下面 济南电缆桥架厂家为您讲解更多相关事项：

The maximum temperature rise of a busbar duct refers to the temperature rise obtained by subtracting the ambient temperature from the stabilized high temperature when the busbar duct is operating at full load with rated current, usually expressed in K. Now, the manufacturer of cable tray in Jinan will explain more relevant matters to you:

母线设计时都会做温升极限实验，温升限制着母线的载流能力，温升高会使得母线的寿命减短、电能损耗提高、电压下降，同时也影响周围环境温度，加速周围设备绝缘材料的老化，甚至引起安全事故。

During the design of busbars, temperature rise limit experiments are conducted, which limit the current carrying capacity of the busbars. Temperature rise can shorten the lifespan of the busbars, increase electrical energy loss, decrease voltage, and also affect the ambient temperature, accelerate the aging of insulation materials for surrounding equipment, and even cause safety accidents.

在我国火灾事故中，属电气引起的火灾事故超出整个火灾事故的60%。而由电气引起火灾事故的肇事者包括：电缆、电线、高低压成套设备、变压器、母线槽、电器元件等，大部分是由于长期温升高发热，导致绝缘材料老化发生短路而引起的火灾事故。

In China, electrical fire accidents account for more than 60% of all fire accidents. The perpetrators of electrical fire accidents include cables, wires, complete sets of high and low voltage equipment, transformers, bus ducts, electrical components, etc. Most of them are caused by long-term temperature rise and heating, which leads to insulation material aging and short circuits, resulting in fire accidents.

极限温升值可以说是母线槽关键的安全技术参数，也是体现母线槽整体性能的一个重要指标。用户从母线槽的温升还可以了解到以下几个问题：

The maximum temperature rise can be said to be a key safety technical parameter of the bus duct, and it is also an important indicator reflecting the overall performance of the bus duct. Users can also understand the following issues from the temperature rise of the bus duct:

①铜排的纯度：含铜量直接与导体的电阻率相关，同样的导体规格电阻率越大，温升自然偏高。

① The purity of copper bars: The copper content is directly related to the electrical resistivity of the conductor. The higher the electrical resistivity of the same conductor specification, the higher the temperature rise naturally.

②导体的截面积：同样的结构和技术、同样含铜量的导体截面积小，温升自然偏高。

② The cross-sectional area of conductors: Conductors with the same structure and technology and the same copper content have a small cross-sectional area, resulting in a naturally high temperature rise.

③母线槽的散热性能：绝缘材料及外壳结构散热不好，温升自然偏高。

③ The heat dissipation performance of the bus duct: The insulation material and shell structure have poor heat dissipation, resulting in a naturally high temperature rise.

④连接头结构的好坏：连接头接触不好，温升也会偏高。

④ The quality of the connector structure: Poor contact of the connector results in a higher temperature rise.
