Description
Technical field
The utility model relates to the power distribution cabinet field of oil field outdoor low voltage power electronic equipment, specifically a kind of multipurpose height protection power distribution cabinet shell.
Background technology
At present, the low-voltage power electronic equipment of the outdoor application in oil field, in equipment runs, self both can produce a large amount of heats, propose high requirement again to the amount of dust entered, the on-the-spot outdoor electricity distribution cabinet run is difficult to reach the basic demand of power electronic equipment to environment.The performance of its product, quality, life-span will reduce greatly, bring very high failure rate, even make the operation that product can not be reliable and stable, to the potential safety hazard that client brings the burden in greatly work, loss in output and produces.
Economically in recent decades to develop rapidly, cause the problem day of environment aobvious severe.North of China by air pollution and airborne dust be stranded.North of China most area wind is large, and make a clear distinction between the four seasons, the desertification of the Northwest causes the north to occur dust and sand weather.Solid dust is discharged in north of China heavy industry, and contaminated air is more serious.Airborne dust, storm, the extreme climates such as snowstorm take place frequently.
Such as Liaohe Oil Field area surroundings, long-term airborne dust, reed wadding, catkin, solid particulate matter and the weather such as wind and rain, wind and snow.If the shell protection grade of low-voltage power distributing cabinet product is low, airborne dust, catkin, catkin, solid particulate matter and some small insects enter the electronic switching device of cabinet inside.Accumulate over a long period, enclosure interior is the increasing dust of many accumulation just, have a strong impact on the heat dissipation capacity of equipment, if humidity becomes large, dust firmly will be bonded at electronic circuit board, switching device is inner, cause certain corrosion, the useful life of the serious equipment that have impact on, cause equipment to run normally.If dust band is conductive, product is broken down, damages, quit work.Visible dust can bring serious consequence on equipment particularly power electronic equipment and production.
The extreme climate such as storm and snowstorm, this weather can make rain or nival belt have certain intensity of pressure to blow to housing towards any angle, and degree of protection does not reach and requires that enclosure interior will enter a large amount of snow and rainwater.Make the equipment in cabinet badly damaged, cause large-area stopping production, the underproduction.Have a strong impact on the output of whole company, cause the huge economic loss on equipment and on producing.Be subject to snowstorm Liaohe Oil Field in 2007 to attack, the heavy snowfall of continuous nearly 20 hours, 1962 mouthfuls, the Liaohe Oil Field disaster-stricken closing well of oil well, affect the daily output 7254 tons, because device housings degree of protection is low, make outdoor rod-pumped well control cubicle and the inner serious accumulated snow of outdoor electricity distribution cabinet, power supply short circuit, the damage of the switching devices such as frequency conversion, cause the stopping production of large area rod-pumped well, because accumulated snow in cabinet is serious and device failure is serious, reproducing of rod-pumped well is made to bring huge difficulty, the removing of inner accumulated snow, the replacing of switching component.Full Oilfield Company is made to receive serious loss in human and material resources, financial resources.
To sum up, the low-voltage power electronic equipment of the outdoor use in oil field, self both can produce a large amount of heats, propose high requirement again to the amount of dust entered in equipment runs.Entering of the heat dissipation ventilation of equipment and dust is the problem of conflict.This just makes the shell of these equipment propose higher technical requirement and difficulty in manufacture.The shell of Oil Field existing equipment, meet heat dissipation ventilation and dust-proof a kind of condition, the degree of protection of its shell does not reach designing requirement.Therefore, a kind of IP grade of exploitation much higher purposes power distribution cabinet shell is badly in need of.Shell protection grade is an important indicator of electric equipment security protection.Which show shell to people close to hazardous components, prevent solid foreign materials, degree of protection that water enters.Its shell protection ability, for the safe operation of equipment, reduces maintenance load, improves and has a great impact useful life etc.
