Description
The application is Application No. 201310137142.8, and the applying date is on April 18th, 2013, and invention and created name is
The divisional application of the application for a patent for invention of " the maintenance error-proof device of substation relay protection and automatics screen cabinet ".
Technical field
The present invention relates to power safety technique field, and in particular to the relay in electric power system in substation secondary device is protected
Mistaken collision preventing, the error-proof device of maloperation when shield and the maintenance of automatics screen cabinet.
Background technology
At present, when substation equipment is overhauled, usual primary equipment can be effectively realized with technical measures or means
Overhauled again after isolation, still, the isolation of relay protection and automatics screen cabinet in secondary device particularly secondary device
Measure is but not perfect enough.The typical representative structure of relay protection and automatics screen cabinet is as depicted in figs. 1 and 2.The screen cabinet is total to
If 6 sets of protection devices shield arrangement altogether, screen cabinet is provided with portions such as some button 5a, air switch 4a, terminal block 3a, the first pressing plate 6a
Part.Due to being contacted between each device by wire in the presence of some, to realize certain control defencive function, therefore, maintenance process
In on by the simulated test of checking device influence can be produced on operating device, make easily operating error action of device, therefore,
Need to remove before maintenance by the contact loop between checking device and running gear, if but split the end of a thread or line nose it is exposed
Outside, then be easily caused personnel touch by mistake, error action of device, it is therefore desirable to reliable isolation；
Terminal block 3a is used to shield equipment in cabinet and is connected with the loop of screen cabinet external equipment to transmit the effect of signal.Due to
Terminal in terminal block is more, causes false protection and staff to prevent from overhauling the operating loop that touches in terminal block of mistiming
Tear open, take by mistake the problems such as operating loop causes false protection by mistake, thus need to isolate the terminal block of running gear and bright before maintenance
Aobvious sign；
Shielding the air switch on cabinet is used to control often the control power supply of set protection device, operation power, due to common screen arrangement,
Respectively the air switch arrangement of set protection device is close, and staff is easily caused during maintenance and divides by mistake, close air switch by mistake.Even if single
The air switch of arrangement, also needs to prevent maloperation, therefore, and air switch keeps correct status to be particularly important during maintenance；
Button 5a on screen cabinet is that human users, control protective unit running status, action logic realize element.Due to
It is switch element, Yi Fashengyin touches the misoperation for causing device by mistake during maintenance, thus button 5a is needed to take safeguard procedures；
Pressing plate on screen cabinet is also named protection in flakes, is the bridge and tie of protection device contact external wiring, is related to guarantor
Can the function of shield and action outlet normally play a role, and common pressing plate has 2 kinds of structures, respectively the first pressing plate 6a and second
Pressing plate 7a.Pressing plate is installed concentratedly in screen bottom, densely distributed, Various Functions, the thing in maintenance caused by miscarrying, missing bruising plate
Therefore it is of common occurrence, therefore, it is necessary to take safeguard procedures to related protection pressing plate before maintenance, prevent accident.
Generally, multiaspect protection screen cabinet can be installed in the protection interior of same transformer station；On the same face protection screen, generally pacify
The many set protection devices of dress, thus during maintenance staff easily because running wrong screen position, admit one's mistake device and protection device in operation
Upper work, so as to directly result in the generation of accident, is also shown in such protector for preventing from running wrong screen cabinet, such as Authorization Notice No. at present
For CN 201682187U Chinese patent literature, disclose a kind of entitled " Extensible warning curtain " is used for transformer station's inspection
The police's curtain repaiied.
But, the error-proof device of complete set, comprehensive relay protection and automatics screen cabinet maintenance is there is no at present.When
It is preceding mostly only with hang Sign Board, the warning simple measures such as cloth to prevent from touching by mistake, maloperation, it is impossible to ensure service work safety,
Cause to touch by mistake, misoperation fault happens occasionally.
