防火桥架电路保护内容是须了解的

随着社会对于重大自然火灾发生时,要保护消防电路设备能够正常使用一段时间,以用来进行消防灭火,不能因为建筑物一发生火灾,里面的消防电路设备就马上不能使用了,导致火灾给社会和人民带来巨大损失,防火桥架就是在这个背景下诞生的。
With the occurrence of major natural fire, the society should protect the fire circuit equipment to be able to use normally for a period of time for fire fighting. The fire circuit equipment inside the building should not be used immediately because of a fire in the building, resulting in huge losses to the society and people. The fire Bridge was born under this background.
该桥架能够在外界环境起火后,保护防火桥架内的电缆不会受到干扰影响,还能够正常工作一段时间,以保证消防工作正常开展。跨接线用在两节桥架之间用来保证电路的通畅,平常状态下一般不会有电流通过。
The cable tray can protect the cables in the fire-proof cable tray from interference after a fire in the external environment, and can work normally for a period of time to ensure the normal development of fire protection work. The jumper wire is used between two bridges to ensure the smoothness of the circuit. Generally, no current will pass through under normal conditions.
如果桥架发生漏电,则电流会通过跨接线相连接的接地保护导体流入大地,从而保证桥架上面不会有积电,避免发生漏电事故保护人身。
If there is leakage in the bridge, the current will flow into the earth through the grounding protection conductor connected with the jumper wire, so as to ensure that there is no accumulated electricity on the bridge, avoid leakage accidents and protect personal safety.
要求金属桥架线路必须有相关接地连接,以保护桥架不会有积电导致发生漏电事故,危及人身。2节桥架跨接处的电阻应小于等于50欧姆。
It is required that the metal bridge lines must have relevant grounding connections to protect the bridge from electric leakage accidents caused by accumulated electricity and endanger personal safety. The resistance at the jumper of section 2 bridge shall be less than or equal to 50 ohms.

每节桥架本身的电阻应小于等于5欧姆,要求非金属桥架线路要单独敷设专用接地线。总之要保护桥架线路的电流的通畅性,不让桥架产生积电。电缆桥架生产厂家供货时都要遵循以上电路保护标准。
The resistance of each cable tray shall be less than or equal to 5 ohms. It is required that the non-metallic cable tray lines shall be separately laid with special grounding wires. In a word, it is necessary to protect the current smoothness of the bridge line and prevent the bridge from generating accumulated electricity. The cable tray manufacturer shall follow the above circuit protection standards when supplying.
防火桥架按照制造材质可以分为金属防火桥架和非金属防火桥架,金属防火桥架的常用材质为镀锌板或经过热镀锌工艺处理后的冷热轧板,两节金属防火桥架连接的时候,如果有连接板且连接板两端都有2个固定螺栓,则这两节金属防火桥架之间可以不使用跨接线。
The fire-proof cable tray can be divided into metal fire-proof cable tray and non-metal fire-proof cable tray according to the manufacturing material. The common material of metal fire-proof cable tray is galvanized plate or hot-rolled plate after hot-dip galvanizing process. When two metal fire-proof cable trays are connected, if there is a connecting plate and two fixing bolts at both ends of the connecting plate, the jumper wire can not be used between the two metal fire-proof cable trays.
山东电缆桥架厂家提醒您,如果没有连接板,则必须用跨接线。非金属防火桥架使用的材质一般为高分子或合成树脂材料,按照标准一般不是用跨接线来保护电路,而是直接使用专用接地导电扁铁。
Shandong cable tray manufacturer reminds you that if there is no connecting plate, jumper wire must be used. The material used for non-metallic fire-proof bridge is generally high polymer or synthetic resin material. According to the standard, the special grounding conductive flat iron is directly used instead of jumper wire to protect the circuit safety.
