A kind of high voltage power transmission and transforming is except condensation assembly
Technical field
This utility model belongs to the technical field of power equipment, specifically, relate to a kind of high voltage power transmission and transforming except condensation total
Become.
Background technology
High-tension switch cabinet inner space is extremely compact, during wet season, makes in switch gear room containing more steam in air
Cable duct moist, cable duct internal water accumulation cannot be got rid of and easily forms steam, and steam is along the gap of cable duct or switch
Before cabinet, the gap such as rear cabinet door, top pressure relief plate penetrates in switch cubicle, can make the insulating part in switch cubicle, electrical body surface or hold
In closing cabinet, there is dew condensation phenomenon local;Thus mould growth, to accelerate metallic conductor corrosion, cause contact surface to aoxidize, contact resistance increases
Greatly, electrical insulation strength is caused to reduce.And cause in-cabinet temperature to be less than the outer temperature of cabinet, inside and outside cabinet, form temperature difference, cause
Dew condensation phenomenon.Cause insulation clearance to cause the generation of flashover electric discharge phenomena creepage, abnormal of electrical equipment, cause phase fault to draw
Play equipment fault tripping operation, bring hidden trouble to the safe and stable operation of equipment.
The main method of the dampness condensation in current domestic general solution switch cubicle has: install additional in cabinet electric heater,
Drive tide agent, the method such as condensation controller, semiconductor dehumidifier machine of installing to control condensation situation in switch cubicle;Or cabinet is carried out
Seal;The pressure relief plate at switch cubicle top is installed blower fan;At switchgear house or switch room, air-conditioning, exhaust fan or movable cabinet type are installed
Dehumidifier etc..
1, electric heater is used: heating in inside switch cabinet local, to solve dew condensation phenomenon, but this method is also
Can not be inherently eliminated condensation, reason is that the method is only to increase the degree of unsaturation of water vapor in air, will not
Steam in cabinet is discharged, and is not reaching to effectively drive tide effect.It addition, the characteristic defective that the sensor of electric heater is intrinsic, right
Relative humidity variations insensitivity, or fixing position is installed does not occurs condensation to cause heater not actuated, in causing switch cubicle
Heating damp-eliminating apparatus does not works, and can reduce anti-condensation reliability, also reduce the security reliability of switch cubicle.3rd, heater
Long-term input, accelerate the aging of the protection device that is arranged on switch cubicle and secondary component, the equipment of switch cubicle caused damage
Bad.
2, tide agent is driven in installation: hangs silica gel bag in switch cubicle or uses other absorbent material, but its water suction
Effect is limited, and the moisture absorbed is difficult to outside waste cock cabinet, and moist steam still concentrates in switch cubicle, effect on moisture extraction
Inconspicuous, operability is poor.
3, condensation controller and semiconductor dehumidifier machine are installed: the condensation controller of installation, semiconductor dehumidifier in switch cubicle
The humid air of local location is simply discharged in cable duct by machine, and in cabinet, the steam in other space (bus-bar room) is still assembled
In switch cubicle, it is impossible to be discharged to outside cabinet, it is impossible to the fundamentally moisture issues in all spaces in solution switch cubicle.Due to
Space in switch cubicle is relatively independent, narrow space in switch cabinet, and new installed equipment is difficult to ensure its peace in cabinet
Full distance.And used equipment can incrementally increase to certain time limit, deviation, after needing switch cubicle to have a power failure when maintenance or more exchange device
Could enter more exchange device in cabinet, the dampness of local space in switch cubicle is simply discharged to outside cabinet by the method, and effect on moisture extraction is not
Substantially, poor operability.
4, blower fan is installed on cabinet top: is swapped by the air of the convection current of air with the external world and reduces switch cubicle endogenous dampness
Degree, cannot to accomplish in cabinet that air fully circulates role limited due to the restriction of cabinet body structure for this scheme, also easily cause dust,
Filthy entrance, it is impossible to reach moistureproof purpose.Owing to the problem in service life of blower fan also can increase the O&M difficulty of operations staff.
5, switch cubicle encapsulation process, clay closure: typically install rubber blanket on door of switch cabinet additional and open with clay closure
Bottom Guan Gui cable vault, strengthen the sealing of switch cubicle, the most only decrease the outside steam entered in chest, do not solve
The certainly problem of humid air in switch cubicle.
6, switch room installs dehumidifier or air-conditioning: installs air-conditioning, exhaust fan or movable cabinet type at switchgear house or switch room and removes
The methods such as wet machine can only improve the surrounding air temperature and humidity conditions of switch room, and the effect playing the humiture in cabinet is the least.
Utility model content
