Problems solved by technology
[0002] At present, the planned maintenance system adopted by most of the power equipment in the power system has serious defects, such as frequent temporary maintenance, insufficient or excessive maintenance, blind maintenance, etc., which makes countries around the world spend a lot of money on equipment maintenance every year
For a long time, my country's power system has implemented a regular maintenance system for power equipment, that is, equipment is tested and maintained according to the planned time period, so there are disadvantages of overhaul and insufficient maintenance
Due to a fault in the power system, it often causes a large-scale power outage
However, the existing power equipment has the problem of relatively high failure rate.

Embodiment Construction
[0013] A method for manufacturing a 500kV semi-enclosed sulfur hexafluoride gas-insulated switchgear, comprising the following steps:
[0014] Divide the inside of the closed switch housing into multiple independent compartments;
[0015] Each compartment is filled with SF6 gas, SF6 gas, according to parts by mass, including sulfur hexafluoride: 99.96 parts, air: 0.013 parts, carbon tetrafluoride: 0.007 parts; moisture: 0.000478 parts, hydrofluoric acid: 0.00012 parts , mineral oil: 0.0004 parts;
[0016] Then install SF6 gas monitoring equipment in each compartment. When the SF6 gas monitoring equipment detects that the leakage rate in the compartment exceeds the set threshold, the SF6 gas monitoring equipment outputs an alarm signal to the alarm.
[0017] And a gas adsorption device is placed in each compartment, and the gas adsorption device is used to adsorb impurities generated inside the compartment to maintain the set electrical characteristics and the safety of mainte...

The invention discloses a method for manufacturing a 500kV semi-enclosed sulphur hexafluoride insulated switchgear. The method comprises the following steps that: the interior of an enclosed switch shell is divided into a plurality of independent compartments; each compartment is filled with SF6 gas; the SF6 gas comprises the following components in parts by mass: 99.96 parts of sulphur hexafluoride, 0.013 part of air, 0.007 part of carbon tetrafluoride, 0.000478 part of moisture, 0.00012 part of hydrofluoric acid, and 0.0004 part of mineral oil; then, SF6 gas monitoring equipment is installed in each compartment; while detecting that the leakage rate in the compartment is beyond a set threshold value, the SF6 gas monitoring equipment outputs an alarm signal to an alarm; furthermore, a gas absorption device is put in each compartment; and the gas absorption device is used for absorbing impurities generated in the compartment, such that set electrical properties and safety of maintenance works can be kept. The advantage that the equipment failure rate is reduced can be realized.
Description
technical field [0001] The invention relates to the field of electric equipment, in particular to a method for manufacturing a 500kV semi-closed sulfur hexafluoride gas-insulated switchgear. Background technique [0002] At present, the planned maintenance system adopted by most of the power equipment in the power system has serious defects, such as frequent temporary maintenance, insufficient or excessive maintenance, blind maintenance, etc., which makes countries around the world spend a lot of money on equipment maintenance every year. For a long time, my country's power system has implemented a regular maintenance system for power equipment, that is, equipment is tested and maintained according to the planned time period, so there are disadvantages of over-maintenance and under-maintenance. A fault in the power system often causes a large-scale power outage. However, existing power equipment has a relatively high failure rate. Contents of the invention [0003] The o...
