Description

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
For deficiency above-mentioned in prior art, in view of the safety specifications of power system, switch cubicle can not take from Cabinet and air supply at the bottom, the mode of air draft, cause atmosphere draught-free in the handcart room in switch cubicle, cable vault, bus-bar room, in cabinet In moist gas makes switch cubicle, primary equipment produces condensation, causes apparatus insulated intensity to reduce, causes the biggest hidden to keeping the safety in production Suffer from, finally will result in electric discharge flashover.
This utility model provides a kind of high voltage power transmission and transforming except condensation assembly, and this had both improved in switch cubicle except condensation assembly The wetness of confined space in the situation of circulation and switch cubicle, decreases the water vapour content in air in cabinet, reduces again The temperature difference in switch cubicle, is allowed to not produce the condition that condensation occurs, plays pre-anti-condensation effect.
