Description
Technical field
The present invention relates to subway work technical field, more particularly to direct-current switch cabinet and channel steel in metro traction electric substation
Connect insulation technology.
Background technology
With the constantly improve of China various regions big and medium-sized cities function, the metro project of various regions comes into effect one after another.In subway
In traction substation, straight-flow system is the part directly being connect with contact net, it carries important directly to power to train
Business, its safe and stable operation are that subway train normal operation must premise.Direct-current switch cabinet is straight in metro traction electric substation
The electric equipments of electric power system are flowed, their safe and stable operation is then traction substation straight-flow system normal operation
Necessary premise, so, the installation quality of 1500V direct-current switch cabinets is great to the influence on system operation of subway system.And it wherein influences straight
Flow the insulation of the mainly cabinet of the installation quality of switchgear.Research finds direct-current switch cabinet and channel steel in metro traction electric substation
The main technical points of connection insulation technology have：(1) subway engineering DC suppling equipment installation quality is to DC power-supply system
It influences；Because subway contact net online be direct current, from single subway substation on the whole, DC equipment it may be said that
It is core equipment, its installation quality directly affects the running quality of whole transformer station, and is associated with whole subway therefrom
The operation situation of circuit, so the installation quality problem to DC suppling equipment should give the attention of topnotch.(2) ironworker
Journey DC suppling equipment installs standard；Since it is desired that consider the protection to being widely present the stray electrical current in subway line region,
Therefore design is strict with DC equipment and should be installed by the way of insulation against ground, this mounting means is to quality, technique etc.
The requirement of aspect is more stringent, while also proposes strict requirements to the research of technique ability of Project Technical, construction personnel.Mesh
The installation of preceding switch cabinet the main problems are as follows：(1) insulation board is saved bit by bit more with channel steel basic part humidity, dust,
Site operation environment is complicated, and constituent parts are reported to the leadship after accomplishing a task construction, and cable interlayer internal water accumulation is deeper, and insulation board lower part dripping phenomenon is serious；(2)
Cabinet and channel steel connection hole deviation are big, and live perforating is using power drill trepanning, and not only stability is not high for power drill trepanning,
And hole position the phenomenon that being susceptible to strabismus, operating personnel need secondary reaming hole, reduce the leakproofness of hole in this way；(3) it is solid
Determine bolt adds insulation spacer to be used cooperatively using galvanized bolt, and switch cabinet body is isolated with basic channel steel in principle, rises
Insulation effect is arrived, in actual installation process, due between bolt and cabinet fixinig plate and naked, in addition hole is inclined
Difference be easy to cause bolt and is in direct contact with cabinet connection sheet, and there are sightless problems, directly result in insulation decline or frame
Voltage leak；(4) bolt hole poor sealing, after in equipment, installation is complete, subway service time is later, and construction site is simultaneously
All completion, other units in charge of construction do not need also to continue to construct, be easy to cause dust, sundries etc. and spread in hole.
