Abstract
The invention relates to a repairing method for silicon rubber casing pipe ageing. The repairing method for silicon rubber casing pipe ageing comprises the following steps of: (1) cleaning an operated and aged synthetic silicon rubber casing pipe, removing dust, salt crust, greasy dirt and other attachments on the surface, and wiping off a pulverized ageing layer; (2) coating with organosilicone glue to close up fissures, and activating the surface of the aged synthetic silicon rubber casing pipe; (3) filling and leveling up with a silicon rubber putty, and rebuilding cracked and damaged positions; (4) rebuilding a damaged sheath and umbrella skirt by a prefabricated silicon rubber strip; and (5) painting PRTV anti-pollution flashover composite coating to form a new completely-covering outer insulation layer. The outer insulation layer has the advantages of simple method, low construction cost, strong durability against pollution and long service life.
Description
Technical field
The present invention relates to the restorative procedure that a kind of transformer station or current conversion station wear out with the silastic elastomer sleeve pipe.
Background technology
Electric energy transmitting just develops towards voltage levels, high load capacity, maximization, remote direction, and the construction of high-energy, superhigh pressure, ultra high voltage and operation have proposed higher specification requirement to power equipment.IEC60815-2008 " selection and the size of the high-tension insulator that uses under the filthy condition are determined part 1: definition, information and rule " has provided the selection and the determining dimensions of insulator, at present, there is the converting equipment of a large amount of basic creep distance deficiencies in electrical network, for satisfying the service requirement under the on-the-spot filthy degree, therefore, compoundization of electroceramics equipment become extensive and basic configuration.
In AC Substation and DC converter station, silastic elastomer insulating sleeve (as current transformer composite bushing, circuit breaker composite bushing, divider composite bushing, smoothing reactor composite bushing etc.) has obtained a large amount of uses, is bearing important power transmission and transformation effect.Because the high electric field action that continues, under harsh meteorology and environmental condition such as illumination, high low temperature, salt fog, acid rain, industrial dirt, chemical corrosion, humidity, will cause the aging of its silastic elastomer overcoat.The running time that this aging phenomenon occurs is all not very long, reaches its useful life far away.
The aging surface hardening that shows of silastic elastomer sleeve pipe, efflorescence, ice crack, degree of depth crackle, full skirt damage, hydrophobicity seriously descends or completely loses, and directly influences the safe operation of system, will bring extremely serious harm as untimely taking measures.Usually, electric power enterprise can only be removed the silastic elastomer sleeve pipe that more renews, and cost is very expensive.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides the aging restorative procedure of a kind of silicone rubber sleeve, its method is simple, and cost is low, and durability against pollution is strong, long service life.
The present invention solves the technical scheme that its technical problem takes: comprise the following steps: the aging silastic elastomer sleeve pipe of (1) cleaning operation, remove dust, salt crust, greasy dirt and other attachment on surface, wipe the aging layer of efflorescence; (2) with the coating of organosilicon glue, make crackle up, the silastic elastomer sleeve surface that activation is aging; (3) fill and lead up, rebuild cracking and damaged position with silicone rubber putty; (4) rebuild sheath and the full skirt of damaging with prefabricated silicon rubber bar; (5) the anti-pollution flashover composite coating of brushing PRTV, the new external insulation layer of formation all standing.
The present invention has the recovery of consolidating, external insulation intensity height, and surface hydrophobicity is good, increases that to climb effect remarkable, and resistant dodges that ability is strong, and anti-rain dodges and the ice and snow sudden strain of a muscle, and advantage more than one times increases the service life.
Embodiment
The present invention includes the following step: the aging silastic elastomer sleeve pipe of (1) cleaning operation, remove dust, salt crust, greasy dirt and other attachment on surface, wipe the aging layer of efflorescence; (2) with the coating of organosilicon glue, make crackle up, the silastic elastomer sleeve surface that activation is aging; (3) fill and lead up, rebuild cracking and damaged position with silicone rubber putty; (4) rebuild sheath and the full skirt of damaging with prefabricated silicon rubber bar; (5) on the sheath of silastic elastomer sleeve pipe, install major diameter additional and increase and climb full skirt, increase creep distance, strengthen and resist that rain dodges, the ability of ice and snow flashover; (6) the anti-pollution flashover composite coating of brushing PRTV, the new external insulation layer of formation all standing.
Described organosilicon glue is one-component normal temperature cure silicon rubber, two component normal temperature cure silicon rubber or liquid silastic.
Described silicone rubber putty is the paste that silicon rubber interpolation white carbon and atom ash filler are made.
Describedly increase that to climb full skirt be the annular umbrella that silicon rubber is made, internal diameter equates that with silastic elastomer sleeve pipe cylindrical shell external diameter is greater than silastic elastomer sleeve pipe full skirt diameter 50～150mm.
Claims (5)
