Description
技术领域technical field
本发明涉及一种耐火防腐电缆槽盒及其加工工艺，属于配电设备技术领域。The invention relates to a fire-resistant and anti-corrosion cable groove box and a processing technology thereof, belonging to the technical field of power distribution equipment.
背景技术Background technique
电缆槽盒，是在防火系统中用于放置电缆的槽盒，由于电缆属于易燃品，由线缆自燃起火或其它原因引发的线缆起火现象时有发生，而且电缆的传导性会使火势很快蔓延到各个角落造成大范围危害，使用耐火电缆槽盒可以有效降低火灾发生率，控制火灾蔓延局势，从而减小火灾损害。The cable trough box is a trough box used to place cables in the fire protection system. Since cables are flammable, cable fires caused by spontaneous combustion of cables or other reasons occur from time to time, and the conductivity of cables will make the fire It quickly spread to every corner and caused a wide range of hazards. The use of fire-resistant cable tray boxes can effectively reduce the incidence of fire, control the spread of fire, and reduce fire damage.
目前，市场上的耐火槽盒（又叫耐火桥架）主要由金属骨架和玻璃纤维增强材料、无机材料的复合防火板、耐火硅酸铝棉毡以及防火基发泡涂料组成。而大部分的生产企业只注重桥架的耐火性能，忽略了它的实际使用环境。此种类型的桥架多数是用于有消防要求的动力电缆敷设上，该电缆负荷大，产生热量也相对较多，而耐火桥架的设计理念首先就是注重如何有效防火隔热，这就产生了矛盾，电缆的热量散发不出去，就会使其长期处于高温状态下运行，也就加速了电缆的老化。而且，在石油、化工等领域对电缆槽盒的防腐、耐受性能要求很高，因此开发具有耐火等级高、防腐耐受性能强、散热好、强度大等优异性能的电缆槽盒是生产发展所需。At present, the refractory trough box (also called refractory bridge) on the market is mainly composed of metal skeleton and glass fiber reinforced material, composite fireproof board of inorganic materials, refractory aluminum silicate wool felt and fireproof base foam coating. However, most manufacturers only pay attention to the fire resistance of the bridge, ignoring its actual use environment. Most of this type of bridge is used for the laying of power cables with fire protection requirements. The cable has a large load and generates relatively more heat. The design concept of the fire-resistant bridge is first of all to focus on how to effectively prevent fire and heat insulation, which creates a contradiction. If the heat of the cable cannot be dissipated, it will run at high temperature for a long time, which will accelerate the aging of the cable. Moreover, in the fields of petroleum and chemical industry, the anti-corrosion and durability requirements of cable trough boxes are very high, so the development of cable trough boxes with high fire resistance, strong anti-corrosion resistance, good heat dissipation, and high strength is a production development. needed.
