Abstract
The invention discloses a 110kV AC gapless metal oxide arrester assembly method, which comprises the steps as follows: an arrester body is arranged on an insulating base and comprises a porcelain jacket and a synthetic insulating jacket, wherein the synthetic insulating jacket wraps the outer surface of the porcelain jacket; an equalizing capacitor is arranged at the top part of the porcelain jacket; pressure release devices are arranged at two ends of an arrester; and an action and leakage current monitor is arranged on the arrester. The advantage of reducing the equipment failure rate is achieved.
Description
Technical field
The present invention relates to field of electrical equipment, in particular it relates to a kind of 110kV alternating current gapless metal oxide arrester assemble method.
Background technology
At present, the scheduled overhaul system that in power system, power equipment uses mostly also exists major defect, and as frequent in provisional maintenance, maintenance deficiency or maintenance surplus, blindly maintenance etc., this makes countries in the world costly in terms of maintenance of equipment every year.And for a long time, China's power system performs periodic inspection system to power equipment, to equipment Inspection and maintenance, thus there is the drawback that maintenance is excessively not enough with maintenance in the most planned time cycle.Because of fault at power train unification, often cause large-area power failure.And there is the problem that fault rate is higher in existing power equipment.
Summary of the invention
It is an object of the invention to, for the problems referred to above, propose a kind of 110kV alternating current gapless metal oxide arrester assemble method, to realize the advantage reducing equipment failure rate.
For achieving the above object, the technical solution used in the present invention is:
A kind of 110kV alternating current gapless metal oxide arrester assemble method, including,
Zinc oxide surge arresters body on insulator foot, described lightning arrester body includes porcelain overcoat and composite insulation overcoat, and described composite insulation outer sheath covers is at the outer surface of porcelain overcoat；
Equalizing capacitor is installed at the top of porcelain overcoat；
Then pressure relief device is installed at spark gap two ends；
Last installation action and leakage current monitor on spark gap.
Preferably, the shell of described action and leakage current monitor uses stainless steel material.
Preferably, it is filled with pressure-fired inside spark gap and is dried insulating gas.
Technical scheme, by improving 110kV alternating current gapless metal oxide arrester assemble method, reduces the purpose of equipment failure rate.
Detailed description of the invention
A kind of 110kV alternating current gapless metal oxide arrester assemble method, including,
Zinc oxide surge arresters body on insulator foot, lightning arrester body includes porcelain overcoat and composite insulation overcoat, and composite insulation outer sheath covers is at the outer surface of porcelain overcoat；
Equalizing capacitor is installed at the top of porcelain overcoat；
Then pressure relief device is installed at spark gap two ends；
Last installation action and leakage current monitor on spark gap.
Preferably, the shell of action and leakage current monitor uses stainless steel material.
Preferably, it is filled with pressure-fired inside spark gap and is dried insulating gas.
The equal galvanizing of ferrum parts that spark gap exposes, composite sheath surface individual defect area is less than 5mm2, and the degree of depth is not more than 1mm, and height of projection is less than 0.8mm, coheres seam height of projection and is less than the 0.2% of composite sheath total surface less than 1.2mm, overall defect area.The outlet terminal of spark gap uses high-strength aluminum alloy or galvanized steel.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
