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 110kV 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: 99.91 parts, air: 0.035 parts, carbon tetrafluoride: 0.035 parts; moisture: 0.00049 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 mainten...

Abstract

The invention discloses a fabrication method of a 110kV SF6 gas insulated semi-closed switchgear. The fabrication method comprises the following steps of partitioning the interior of a closed switch shell into a plurality of independent compartments; filling each compartment with an SF6 gas, wherein the SF6 gas comprises the following constituents by mass: 99.91 parts of sulfur hexafluoride, 0.035 part of air, 0.035 part of carbon tetrafluoride, 0.00049 part of water, 0.00012 part of hydrofluoric acid and 0.0004 part of mineral oil; installing an SF6 gas monitoring device in each compartment, and outputting an alarm signal to an alarm by the SF6 gas monitoring device when the leakage rate, detected by the SF6 gas monitoring device, in the compartment exceeds a set threshold value; and placing a gas absorption device in each compartment, wherein the gas absorption device is used for absorbing impurities generated in the interior of the compartment so as to maintain set electrical characteristic and the safety of maintenance operation. By the fabrication method, the advantage of reducing the fault rate of the device is achieved.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to a method for manufacturing 110kV 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 object...
