Abstract

The invention relates to a method for cleaning a transformer cooler, in particular to a method for cleaning the transformer cooler through spraying and hot-line water washing, belonging to the field of power equipment maintenance, aiming at solving the problems that the transformer cooler cleaning effect is poor and the cleaning operation time is long when the existing method is used for cleaning the transformer cooler. The method for cleaning the transformer cooler through spraying and hot-line water washing mainly comprises the following steps of: 1, spraying for softening: using atomizing nozzles to spray softening cleaning liquid onto solid dirt such as poplar catkins and cotton fibers which are adhered onto the transformer cooler; 2, primary hot-line water washing; 3, decontamination: filling decontaminating cleaning liquid into a cleaning liquid pressurizing device and using the atomizing nozzles to spray the decontaminating cleaning liquid onto oily dirt which is adhered onto the surface of the transformer cooler; and 4, secondary hot-line water washing: using high-pressure water to conduct hot-line water washing on the oil dirt on the surface of the transformer cooler. The method provided by the invention can be used for cleaning the transformer cooler.

Description

Adopt spraying and charged water to clean the method for transformer cooler

Technical field

The present invention relates to a kind of method of cleaning transformer cooler, be specifically related to a kind of method that spraying is cleaned and charged water cleans transformer cooler that adopts, belong to the electric equipment maintenance field.

Background technology

Be subjected to the impact of natural environment, the dirts such as some insects, dust, Yang Xu are accumulated between the transformer cooler cooling tube easily, add transformer Cooling pipe overmatter, aggravated the pollution level that transformer cooler is subjected to environment, not only worsened the radiating effect of cooler, affected the transformer belt load-bearing capacity, make simultaneously the transformer oil quality deterioration, bring hidden danger for device security stable operation, and the maintenance workload of transformer cooler is strengthened, particularly to its cleaning, a lot of difficulties have been caused.

At present transformer cooler being cleaned is the method that adopts the water flushing, but there is following shortcoming in this mode, 1) because the too tight slit of cooling tube manufacturing is too little, fouling products firmly is fixed between the slit of cooling tube, do not obtain fully dark and damp before, water jets under high pressure is stamped, to be difficult to disposable penetrating, so must be that first pass is dark and damp, softening, just can play the effect of flushing second time, but on-the-spot living water washing effect be not bery desirable; 2) one or two layers dirt along with water column punching between three or four layers, increased the penetrating resistance of water column so that three or four layers be difficult to punching thoroughly, especially some insects, cotton-wools calculate with 4 groups of YF1-200 coolers, the Global Operation time approximately needs 7-8 hour.

Summary of the invention

The objective of the invention is to adopt existing mode for solution and clean transformer cooler, the cleaning performance of transformer cooler is poor, the problem that the washing and cleaning operation time is long, and then a kind of method that adopts spraying and charged water cleaning transformer cooler is provided.

The present invention addresses the above problem the technical scheme of taking to be: employing spraying of the present invention and charged water clean the method for transformer cooler to carry out according to following steps,

Step 1, spraying are softened, the implantation quality percent concentration is the softening agent cleaning fluid of 3%-5% in the cleaning fluid pressue device, through the cleaning fluid output pipe and control the cleaning fluid control valve, will soften cleaning fluid by atomizer and be sprayed on the poplar wadding and cotton-wool solid dirt that is attached on the transformer cooler; Described softening agent is wooden softening agent;

Step 2, a living water washing, after solid dirt is softening through 20min～30min, then, injected water in cleaning machine, through the water under high pressure that high-pressure hose and giant eject poplar wadding and cotton-wool solid dirt after softening are carried out living water washing, the nozzle diameter of described giant is 8mm～12mm;

Step 3, decontamination, in the cleaning fluid pressue device, inject the decontamination cleaning fluid, through the cleaning fluid output pipe and control the cleaning fluid control valve, by atomizer the decontamination cleaning fluid is sprayed at and is attached on the lip-deep oils dirt of transformer cooler, reduce the surface adhesion force of oils dirt;

Step 4, secondary living water washing adopt water under high pressure that the lip-deep oils dirt of transformer cooler is carried out living water washing, remove the lip-deep oils dirt of transformer cooler, and the nozzle diameter of described giant is 8mm～12mm.

The invention has the beneficial effects as follows: the present invention adopts first softening cleaning fluid to be sprayed on the transformer cooler, with the softening cleaning of dirt, then, use the living water washing transformer cooler, the experiment proved that, can obviously improve cleaning quality, cleaning performance is good, shorten the washing and cleaning operation time, guaranteed that effectively the good heat radiating of transformer cooler ventilates, avoided the thus hidden danger of transformer bad condition generation.The present invention cleans thoroughly, and is convenient, safety.Greatly shortened the washing and cleaning operation time, calculated with four groups of YF1-200 coolers, the Global Operation time has approximately shortened 2-3 hour.

Description of drawings

Fig. 1 is the softening process schematic diagram of processing poplar wadding and cotton-wool solid dirt of the present invention, and Fig. 2 is the process schematic diagram that the oils dirt is processed in decontamination of the present invention.

The specific embodiment

The specific embodiment one: in conjunction with Fig. 1 and Fig. 2 present embodiment is described, the method that the employing spraying of present embodiment and charged water clean transformer cooler is carried out according to following steps,
