Description
Technical field
The utility model belongs to electrical engineering technical field, relates to a kind of extra-high voltage climate cell icing spray equipment, the suitable climate cell's spray system of extra-high voltage equipment being carried out to ice-coating test of this device.
Background technology
In recent years, icing problem for research extra-high voltage electric transmission and transformation equipment, opened the construction of extra-high voltage climate cell, in extra-high voltage climate cell, empty diameter is over 20 meters, head room is over 24 meters, when carrying out ice-coating test, need to adopt spray equipment to spray to extra-high voltage equipment, thereby can make it form icing, and traditional spray equipment that at present artificial ice-coating test adopts has following defect: 1) shower nozzle is placed on wall, equipment under test can only be placed in the central authorities of testing laboratory, and therefore effectively jet length at least needs 10 meters.And shower nozzle is effectively sprayed water apart from 7 meters of less thaies, water cannot be sprayed onto on equipment under test; 2) shower water lacks pre-cooled program, often cause the temperature of icing to reach below subzero 10 degree, and the water droplet of natural icing is supercooling water droplet, the temperature of icing is generally spent to 7 degree subzero 1, this just causes the weather conditions of artificial icing and natural icing inconsistent, affects the authenticity of result of study; 3) tradition adopting is at present sprayed shower nozzle at a distance, and its injection flow rate is larger, and water spray drop diameter is larger, and the water spray drop diameter that ice-coating test needs should be less than 500 microns of Ф, causes so required refrigerating capacity bigger than normal, has strengthened cost therefore economy is poor.
Utility model content
The technical problems to be solved in the utility model is, backward situation for prior art, design a kind of improved extra-high voltage climate cell icing spray equipment, use this device to carry out pre-cooled to icing water, strengthen the water spray distance of shower nozzle, reduce icing water consumption, dwindle drop diameter, reduce experimentation cost.
The technical solution of the utility model is, above-mentioned extra-high voltage climate cell icing spray equipment, referring to Fig. 1, it is by the freezing output unit of an icing water generates device 1, refrigeration unit 2, an air atomizing jet head sets 3 with the Induced fan 4 that pipeline connects with it, and an air compressor 5 forms.The pipeline at output of the freezing output unit 2 of wherein said refrigeration unit connects the input end of icing water generates device 1.The pipeline at output of icing water generates device 1 connects the water inlet of air atomizing jet head sets 3.The air inlet duct of air atomizing jet head sets 3 connects the output terminal of air compressor 5.The extra-high voltage of the present utility model climate cell icing forming is thus placed in the central authorities of extra-high voltage climate cell while using with spray equipment, air atomizing jet head sets 5 is arranged on the wall of testing laboratory.Make the Induced fan 4 of air atomizing jet head sets 3 near thereafter, and the air-out direction of Induced fan 4 and the water outlet direction of air atomizing jet head sets 3 are consistent.
Principle of work of the present utility model is: extra-high voltage climate cell icing is according to the demand of test with the effect of the icing water generates device 1 of spray equipment, produces the icing water of respective electrical conductance, and icing water is carried out to cooling and insulation.While extra-high voltage equipment being carried out to artificial icing in extra-high voltage climate cell, it is chilled water that the freezing output unit 2 of refrigeration unit produces overcooled ethylene glycol solution, in pipeline input icing water generates device 1, make icing water water temperature be down to 1～3 degree Celsius of output.The water outlet of icing water generates device 1 enters the water inlet of air atomizing jet head sets 3 through water pipe.The pressurized air of air compressor 5 enters the air intake opening of air atomizing jet head sets 3 through pipeline.Air atomizing jet head sets 3 starts to play a role, and its effect has two, and the one, icing water and the pressurized air of the 3 interior pressurizations of air atomizing jet head sets are mixed, make water droplet atomization, the median diameter of water droplet is less than Ф 200 μ m; The 2nd, the angle of adjustment spray and height are to meet the needs of test.
The Induced fan 4 of air atomizing jet head sets 3 rear sides blows out induced air, due to as mentioned above, the water outlet direction of the air-out direction of Induced fan 4 and air atomizing jet head sets 3 is consistent, again because the particle of water droplet is little, from heavy and light, under induction wind action, greatly lengthen water spray distance, made maximum water spray distance can reach 18m, can meet the needs of test completely.Thus one, the refrigeration work consumption of refrigeration unit reduces, and kinds of artificial icing form is achieved.
The beneficial effects of the utility model are:
1), can regulate by system the different artificial icing forms of realization;
2), because water spray distance strengthens, therefore can select nature water spray distance shorter, the shower nozzle that injection flow rate is less and water droplet median diameter is less;
3), because water droplet median diameter is little, aquifer yield is little, and icing water has been carried out pre-cooled, thereby alleviated the refrigeration burden of refrigeration unit, reduced cost, remarkable in economical benefits;
4), solved the artificial ice-melt of traditional extra-high voltage climate cell's icing temperature and natural icing temperature inconsistent, and artificial icing only can form a difficult problem for glaze form.
