Description
The present invention relates to a kind of unit equipment that all kinds of insulators of high-tension transformation equipment external insulation and transmission line of electricity porcelain glass insulation sub-surface is carried out living water washing.
The insulated porcelain sleeve of outdoor substation equipment and transmission line of electricity porcelain glass insulator long term exposure are in air, and insulator and insulator surface contamination are inevitable.In order to recover the dielectric level of insulator and insulator, prevent the generation of pollution flashover accident, must remove insulator and insulator surface contamination.Transformer station's external insulation insulator surface contamination sweep-out method now is the artificial cleaning that has a power failure, machinery cleaning and water flushing.Transmission line of electricity porcelain glass insulator surface contamination sweep-out method now is artificial have a power failure cleaning and use " wind-driven cleaning ring for insulator ".The artificial cleaning that has a power failure is wasted time and energy, and the cleaning effect is difficult to ensure, has reduced delivery simultaneously, brings influence for the national economy and common people life; The machinery cleaning expends very big manpower, labour intensity is big; Big current flushing causes flashover fault easily as misoperation, and consumes a lot of water resources; " wind-driven cleaning ring for insulator " is subjected to geographical environment and climatic factor, and use is restricted, and " wind-driven cleaning ring for insulator " only strings effect to crossing line, can't use on the strain insulator-string.
The objective of the invention is to overcome the deficiency in the existing anti-pollution flashover technology, a kind of water that utilizes of design washes and removes filthy " ring-type is controlled " unit equipment transformer station's external insulation insulator, the transmission line of electricity porcelain glass insulator surface contamination of operation.
The objective of the invention is to realize by the following method: the water pipe of more piece ring-type is installed around transformer station's external insulation insulator, the transmission line of electricity porcelain glass insulation substring, and the ring-type water pipe is connected with water main; A plurality of water nozzles are installed on every water saving pipe, and water nozzle water outlet direction is all aimed at the surface of converting equipment insulator, transmission line of electricity porcelain glass insulator; Water main is provided with discharging valve bottom; Water main, the ring-type water pipe, water nozzle and on insulator, insulator fixedly the equipment of usefulness be insulating materials and make; Every joint ring-type water pipe is connected with water main by valve, and actuator and controller on the valve join by lead; Every joint ring-type water pipe is connected with feed pump by water main with valve; The water quality that is complementary supplies water to every water saving pipe through feed pump, opens valve by controller commander actuator, and water is gone out from water nozzle, beginning water flushing operation; Washed each joint, controller commander actuator is to the water yield of this joint of minor adjustment or close this joint valve; Open a last joint valve of this joint simultaneously, this joint is implemented the flushing operation; To this transformer station's external insulation insulator, transmission line of electricity porcelain glass insulation sub-surface whole flushing study carefully finish after, close feed pump earlier, send instruction by controller then, actuator is opened discharging valve, the water in the emptying water pipe; Tear open at last and move water pump and wait until that next operating point carries out operation.
On every water saving pipe, settle insulating materials to make rotatable small fan, its objective is that gentle breeze blows the fan rotation, frighten and drive birds away, prevent that bird from building nest between insulator chain and water pipe; The fan rotation changed the direction of air-flow and increases air velocity when strong wind blew, and can remove the dirt on insulator and insulator chain surface.
With prior art relatively, the present invention has the following advantages:
1, to dissimilar converting equipment insulated porcelain sleeves, transmission line of electricity porcelain glass insulation substring, the ring-type water pipe of design different size; Can finish flushing, also realize cleaning the electric transmission line isolator surface to all kinds of converting equipment insulated porcelain sleeves.
2, carry out water flushing operation in time, easily according to the contamination situation.
3, prevent that the sewage line from forming; Do not have influence on the equipment that closes on.
4, the behaviour operating personnel send instruction by controller and pursue the joint flushing by " ring-type is controlled " equipment, change original manually Hand flushing device material by the mode of joint flushing, reduce labor intensity of operating personnel.
5, not contact electrification of operating personnel equipment, the no longer operation of ascending a height, the personal safety performance that has improved.
6, reduce personnel's input, reduce the water consumption of flushing.
