Abstract
The invention relates to a method for laying cables in a benzene hydrogenation engineering protection tube. The method is characterized by comprising the following steps that a) the protection tube exposed out of the ground is shortened or lengthened; b) cable heads are fastened by a non-corrosive lubricant, iron wire or steel wire; and c) after the cables penetrate the protection tube and are laid, an opening of the protection tube is closed plugged. The method for laying the cables in the benzene hydrogenation engineering protection tube is reasonable in design, simple in operation, safe and reliable in engineering, excellent in electrical performance and lower in engineering cost.
Description
Technical field
The present invention relates to a kind of cable laying method of electric equipment, specifically, is a kind of method that benzene hydrogenation engineering protection tube inner cable lays.
Background technology
The technique of benzol hydro refining unit is more special, its system complex, and equipment is many, and the pressure of system own, temperature are higher, and pumping unit does not allow idle running.Benzene hydrogenation engineering be mainly divided into central control room and electric substation, refining plant, water supply and sewage work, air compression station, storage and handling facility (tank field and pump house), full factory powers and the illumination of full factory, torch and engineering affiliated facility, in the electrical install of these facilities, have lightning protection, fire prevention, explosion-proof particular/special requirement, wherein laying of cable is important step in whole electrical system.Current domestic built or be still in the stage lack of standardization the laying of cable of building benzene hydrogenation engineering equipment, there is a lot of not science, irrational place, manufacturing process is numerous and diverse, manufacturing cost is high.
Therefore the method that known benzene hydrogenation engineering protection tube inner cable lays also exists above-mentioned all inconvenience and problem.
Summary of the invention
Object of the present invention, is the method that a kind of safe and reliable benzene hydrogenation engineering protection tube inner cable of proposition lays.
For achieving the above object, technical solution of the present invention is:
The method that benzene hydrogenation engineering protection tube inner cable lays, is characterized in that comprising the following steps:
A, first the protection tube basseted to be drawn on the strong points to offset the weaknesses, not affect the handling of equipment; The mouth of pipe height of protection tube arranged side by side needs consistent, smoothly protect wedge angle, the burr of mouth of pipe inner circle with file process, then with iron wire or steel wire bind cotton yarn, rag drags back and forth in protection tube, to remove foreign object in pipe or ponding;
B, pinion cable end with non-corrosive lubricant or with iron wire, steel wire, and trailing cable is through protection tube;
C, cable are through protection tube and after having laid, tightly the mouth of pipe is protected in shutoff.
The method that benzene hydrogenation engineering protection tube inner cable of the present invention lays can also be further achieved by the following technical measures.
Aforesaid method, wherein said cable protection pipe is the welded still pipe of zinc-plated low-pressure fluid conveying.
After adopting technique scheme, the method that benzene hydrogenation engineering protection tube inner cable of the present invention lays has the following advantages:
1, making step is reasonable in design, simple to operate;
2, safe and reliable, the excellent electric properties of project quality;
3, engineering cost is reduced.
Embodiment
The present invention is further illustrated below by way of specific embodiment.
Embodiment 1
The method that benzene hydrogenation engineering protection tube inner cable lays, is characterized in that comprising the following steps:
A, the method for laying at protection tube inner cable specify by GB50397-2007 " metallurgical electric equipment project installation acceptance specification " 24.1.3, forbids surface insulated conductor, first be drawn on the strong points to offset the weaknesses by the protection tube basseted, not affect the handling of equipment; The mouth of pipe height of protection tube arranged side by side needs consistent, smoothly protect wedge angle, the burr of mouth of pipe inner circle with file process, then with iron wire or steel wire bind cotton yarn, rag drags back and forth in protection tube, to remove foreign object in pipe or ponding; Described cable protection pipe is the welded still pipe of zinc-plated low-pressure fluid conveying;
B, pinion cable end with non-corrosive lubricant or with iron wire, steel wire, and trailing cable is through protection tube;
After c, cable have laid through protection tube, the tightly shutoff protection mouth of pipe.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or change.Therefore, all equivalent technical schemes also should belong to category of the present invention, should be limited by each claim.
