Description

The artificial moist heat de-icing method of transformer station and the deicing system
Technical field
The present invention relates to substation monitor field, be specifically related to the artificial moist heat de-icing method of transformer station and The deicing system.
Background technology
Sleet is made up of mixture of ice and water, and the object collision precipitation that immediately freezes of the temperature less than 0 DEG C, be early winter or A kind of diastrous weather that time at the beginning of last month of spring in winter is seen.Raindrop less than 0 DEG C can be kept in the air that temperature is slightly below 0 DEG C Supercooled state, its outward appearance is identical with general raindrop, when it is fallen on the object that temperature is less than 0 DEG C, is frozen into appearance at once Smooth and transparent ice sheet, referred to as glaze.Serious glaze can break trees, electric pole, stop communication, power supply, hinder public Road and railway traffic, threaten the flight safety of aircraft.
During the Spring Festival in 2008 occur south China ice and snow weather, cause Hunan, Jiangxi, Guizhou, Hubei, Guangxi, The power supply major network of the province such as Zhejiang and Anhui partly or entirely interrupts, and the power network of drug in some provinces even exits bulk power grid independent operating. Had a power failure on a large scale caused by current ice and snow weather, bring massive losses to national economy, it is main reason is that each province's main high voltage Transmission line of electricity can not be loaded beyond the icing thickness of design standard, so that transmission line of electricity weight increases, it is defeated finally to forget about it high pressure Electric pole tower forms power failure.Meanwhile ultra-high-tension power transmission line is difficult to open up all in the severe field of geographical environment, rescue greatly Open, restorative job schedule is slow.
Existing clearing ice technology is all manually to use deicing tool deicing, due to the influence of weather, especially wind direction and wind velocity Influence, existing deicing tool or deicer, it is necessary to which manual operation, due to the particular surroundings of transformer station, manual operation is all Potential safety hazard be present.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of artificial moist heat de-icing method of transformer station and the deicing System.
The purpose of the present invention is realized in the following manner:
A kind of artificial moist heat de-icing method of transformer station, methods described include:
Step 1:Local climate data is consulted, surface air temperature is found out in -10 DEG C~3 DEG C sections while includes the weather of precipitation The wind direction and wind speed climatological data of key element;
Step 2:Determine the scope that the outdoor in transformer station location prevents sleet from freezing;
Step 3:The scope that is prevented sleet from freezing according to determined by step 2, and climatological data in step 1 determine The scope of outside transformer substation icing scope upwind side;
Step 4:Natural gas line is buried in the scope of outside transformer substation icing scope upwind side, and is spaced and sets up day Right gas jets, if it find that there is sleet, natural gas is lighted in direction of being in the wind, and hot-air is blown to the model for preventing freezing by upwind side Enclose so that weather is all warm in the range of this, prevents from freezing.
Magnetic valve is set on each nozzle of described natural gas line, and described magnetic valve is connected with controller.
Prevent sleet from thermometer, anemoclinograph, rainfall gauge are set in the range of freezing in the outdoor in transformer station location, When unattended to have detected super-cooling waterdrop, while wind direction and wind velocity at that time is detected, then according to wind at that time Actually determine to need the scope of the nozzle of the natural gas of upwind side opened at that time to wind speed, and control the big of nozzle blowing force It is small, the scope for preventing freezing is blown to from upwind side toward leeward so that warm weather is kept in the range of this.
A kind of artificial moist heat deicing system of transformer station, including controller, and the natural gas being connected with controller Magnetic valve on plumbing nozzle, be arranged on transformer station prevent sleet freeze in the range of thermometer, anemoclinograph, rainfall Meter, thermometer, anemoclinograph, udometric signal described in described controller real-time reception, and send control command extremely The magnetic valve of the nozzle of the natural gas of upwind side, and control the size of nozzle blowing force.
The present invention determines the outdoor icing time limit in transformer station location, frozen according to the climatological data in transformer station location Precipitation in time limit, the position of the interior wind direction and wind velocity and environment temperature, as required deicing in the time limit that freezes, according to these gas Index is waited, with reference to aerodynamic principle, determines hot-air source of the gas position and jet velocity, automatic de-icing, without manual operation, Eliminate manually-operated potential safety hazard.
Brief description of the drawings
Fig. 1 is the plane of arrangement figure of the embodiment of the present invention 1.
Wherein 1 is natural gas line, and 2 be nozzle.
Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
A kind of artificial moist heat de-icing method of transformer station, methods described include:
Step 1:Local climate data is consulted, surface air temperature is found out in -10 DEG C~3 DEG C sections while includes the weather of precipitation The wind direction and wind speed climatological data of key element;
Step 2:Determine the scope that the outdoor in transformer station location prevents sleet from freezing;
Step 3:The scope that is prevented sleet from freezing according to determined by step 2, and climatological data in step 1 determine The scope of outside transformer substation icing scope upwind side, such as the scope for the wind direction that surface air temperature is in -10 DEG C~3 DEG C precipitation,
Step 4:Natural gas line is buried in the scope of outside transformer substation icing scope upwind side, and is spaced and sets up day Right gas jets, if it find that there is sleet, natural gas line is lighted in direction of being in the wind, and hot-air is blown to by upwind side to be prevented from freezing Scope so that weather is all warm in the range of this, prevents from freezing.
