Description
Technical field
The peripheral equipment field the present invention relates to high-voltage board is powered, particularly relates to a kind of disconnecting switch service work and puts down
The processing technology of platform.
Background technology
10kV high-voltage boards will unavoidably cause separating brake due to running the reasons such as the long time limit, ageing equipment and frequent operation
Coil burnout, and then need the problem of emergency opening.
In the 10kV high-tension switch cabinets that transformer station sets up, due to running the reasons such as the permanent, ageing equipment of the time limit, Jing often occurs
Separating brake process burns switching winding, it is impossible to the urgent defect of normal distant place separating brake.If now switch internal or outside line go out again
Existing failure, protection act but cannot separating brake, it will cause switch blast, bypass the immediate leadership jump 10kV mothers and main transformer switch, 10kV buses
The power grid accident of decompression, it is therefore necessary to take the measure of emergency opening.The switching winding that power failure more renews, as early as possible switchs on switch
Inspecting state, distant place control loop breaks, can only be by live manual brake separating on the spot.On-load Manual local separating brake on the spot,
Electric power safety code is not allowed, and with certain danger, if now switch cubicle failure causes inseparable or short circuit, will be caused out
Vacuum bubbles explosion is closed, huge personal injury and power grid accident is caused.If had a power failure by whole section of bus every time, then by failure high pressure
Cabinet has a power failure and changes switching winding, it is assumed that every time bus stops power transmission operation needs 3 hours, 15 10kV circuits is averagely related to every time, often
The average power transmission load of bar circuit is 0.433 ten thousand kW.If there is above-mentioned situation, it will cause serious impact to residential electricity consumption,
Therefore maintainer must be arranged to be overhauled to scene.
As shown in figure 1, the figure is current high-tension electricity erecting structure, it is by bolt erection by some U-type groove steel plates 6
Into hanging in the middle of platform, the steel plate of upper lateral is liftoff at least 3 meters, even up to more than 10 meters of height.Maintenance teams and groups' day
Chang Bixu carry out on the narrow framework channel-section steel of disconnecting switch junction block, dynamic/static contact, fingertip conducting rod, insulator, grounding switch,
The repair and maintenance work of the parts such as base assembling, task is quite heavy, and operating position is narrow, staff's standing foothold compared with
It is little, lack be hanging safety belt position, it is impossible to exert a force, dismounting inconvenience.When high pressure equipment breaks down, maintainer is by station
Stand on the steel plate for having set up, high pressure equipment is overhauled, although there is safety line in maintainer system, but in moving process
In, its foothold is simply walked up and down between steel plate, is very easy to drop, threat to life safety.Therefore, maintainer is right
It is both inconvenient during this disconnecting switch debugging and maintenance, and with certain danger.
