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，下面 山东电缆桥架厂家为您解说。

The limit temperature rise can be said to be the key safety technical parameter of the bus duct, and also an important indicator reflecting the overall performance of the bus duct. The user can also understand the following problems from the temperature rise of the bus duct, and the Shandong cable bridge manufacturer will explain for you.

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。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。

The limit temperature rise of the bus duct refers to the temperature rise obtained by subtracting the ambient temperature from the stabilized high temperature when the bus duct runs at full load through the rated current, usually expressed in K. The temperature rise limit test will be conducted during the design of the bus. The temperature rise limits the current carrying capacity of the bus. The temperature rise will shorten the life of the bus, increase the power loss, and reduce the voltage. At the same time, it will also affect the ambient temperature, accelerate the aging of the insulation materials of the surrounding equipment, and even cause safety accidents.

在火灾事故中，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。

Among the fire accidents, the fire accidents caused by electricity account for more than 60% of the total fire accidents. The perpetrators of fire accidents caused by electricity include cables, wires, high and low voltage complete sets of equipment, transformers, bus ducts, electrical components, etc. Most of them are fire accidents caused by aging insulation materials and short circuit due to long-term temperature rise and heating.

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 Purity of copper bar: the copper content is directly related to the resistivity of the conductor. The higher the resistivity of the same conductor specification, the higher the temperature rise.

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 Cross-sectional area of conductor: with the same structure and technology and the same copper content, the cross-section area of conductor is small, and the temperature rise is naturally high.

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 Heat dissipation performance of bus duct: insulation material and shell structure are poor in heat dissipation, and the temperature rise is naturally high.

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: if the connector contact is not good, the temperature rise will also be high.

母线槽在使用的时候，防水措施一定要好，因为当水进入到母线槽内部的时候，会使得母线槽的绝缘性能变差，长期这样使用会导致母线槽短路，使得供电出现问题，这样会影响工作。虽然母线槽本身有很好的防水措施，但是为了以防万一在安装的时候，也要有一定的防水的防护措施。

When the bus duct is used, the waterproof measures must be better, because when the water enters the bus duct, the insulation performance of the bus duct will become worse. Long-term use will lead to short circuit of the bus duct, causing power supply problems, which will affect the work. Although the bus duct itself has good waterproof measures, certain waterproof protection measures should be taken in case of installation.

当母线槽在楼层中穿越的时候，一定要找一个好的穿着点，这样避免因为天气不好楼层之间相互漏水影响母线槽的使用，如果母线槽在使用中出现故障还有可能会给用户带来一定的损伤，所以要注意不管母线槽在什么地方使用都要注意它的防水措施！更多相关内容就来我们网站 //www.comprepyme.com咨询了解！

When the bus duct passes through the floor, it is necessary to find a good place to wear it, so as to prevent the use of the bus duct from being affected by water leakage between floors due to bad weather. If the bus duct breaks down in use, it may also cause some damage to the user, so it is necessary to pay attention to its waterproof measures no matter where the bus duct is used!
