Description
Technical field
The present invention relates to a kind of method that secondary device cleans, relate in particular to a kind of secondary device method that safety is cleaned in charging operation situation.
Background technology
Electrical equipment (Electrical Equipment) refers to the general designation to equipment such as generator, transformer, power circuit, breakers in power system, mainly comprises primary equipment and secondary device.Primary equipment refers to be directly used in produces and uses electric energy, the electrical equipment higher than secondary device voltage, mainly comprises generator (motor), transformer, breaker, insulator, isolating switch, automatic switch, contactor, knife-like switch, bus, transmission line of electricity, power cable, reactor, motor etc.Secondary device refers to the accessory equipment that primary equipment is supervised, measures, controls, protects, regulated, and comprises meter meter, as voltmeter, ammeter, power meter, the electric energy meter electrical parameter for measuring circuit; Insulating monitor; Control and recoil simulator, as terminal box, control box, observing and controlling cabinet, shared device cabinet; Relay protection and automatics, as relay, automatics, relay-set, power distribution cabinet etc., for monitoring the operation conditions of primary system, abnormal reaction and accident, then act on breaker rapidly, protects control; DC power supply device, as batteries, dc generator, silicon rectifier device, control flow, switch cubicle etc., supplies with and controls the dc source of protection use and with DC load and emergency lighting electricity consumption etc.; High-frenquency current blocking device, terminal box, mechanism case and other.
Visible secondary device is highly sophisticated device, and the maintenance requirement of equipment is more taller than primary equipment, the major requirement of safeguarding of primary equipment guarantees electric insulation, and the maintenance of secondary device guarantees electric insulation except requiring, and also combustibility, corrosivity, toxicity is had to strict requirement.Secondary device produces all kinds of dirt particles of absorption that potential difference and static can directivity in running, unavoidably can adsorb the fouling products such as dust in atmospheric environment, greasy dirt, moisture, salinity, metal dirt, charcoal stain and form to pile up.Affect the normal heat radiation of each assembly in electric panel cabinet, cause temperature anomaly to raise, also make the easier moisture absorption of each assembly in electric panel cabinet, cause insulation to decline; More may directly cause each assembly loose contact in electric panel cabinet, easily on circuit board, form short circuit or microcircuit, may cause control, measuring and controlling equipment dropout, distortion; Under wet condition, these pollutants that contain salt, acid, alkaline matter become electrolyte, electric conductivity strengthens, and insulaion resistance reduces, and leakage current increases, easily cause short circuit, electric arc, heat radiation is bad and the accident such as equipment malfunction work, these all will form larger potential safety hazard.
Traditionally, the way of cleaning fouling products is in the situation that cutting off the electricity supply, with hairbrush or the wiping of cloth tiger, this method inconvenient operation, the gap that hand reaches cannot be cleared up, and inefficiency, cleaning effect is poor, security is low, also carries out in the situation that cutting off the electricity supply, the equipment that affects moves normally.Grid cut-off cannot be powered, and greatly affects the normal work of people and life.In recent years, people start to research and develop some products and try hard to improve this situation, the Chinese patent that is 200810140989.0 such as application number discloses a kind of high-pressure electrification detergent, by weight percentage, by transformer oil 40-50%, naphtha 40-50%, clear solvent naphtha 7-11% and bleeding agent 0.5-1.5%, total amount is 100% as raw material, to make, and packs above-mentioned raw materials into stirred tank, under 10-20 ℃, 1 atmospheric pressure, reacts and can be made into for 1.5-2.5 hour.Although this high-pressure electrification detergent has the feature of high insulation, but just the insulator for on-line operation cleans, insulator belongs to primary equipment, during cleaning, only require and guarantee electric insulation, combustibility, corrosivity, toxicity etc. are not required, and the contained composition of this high-pressure electrification detergent is oiliness cleaning material, after cleaning, can form one deck oil film, if be applied in the secondary pollution that very easily causes greasy dirt on the highly sophisticated devices such as secondary device, and physics and electrical characteristic due to secondary device, can cause a lot of safety problems.Up to the present, for secondary device, in charging operation, carry out the research that safety cleans and remain blank out, how to realize safety, efficiently secondary device carried out to charged cleaning and remain and be difficult to the problem that breaks through.
Summary of the invention
