Description
Technical field
The present invention relates to power safety technique field, the mistaken collision preventing when relay protection being specifically related in electric power system in substation secondary device and the maintenance of automaton screen cabinet, the error-proof device of maloperation.
Background technology
At present, when substation equipment overhauls, usual primary equipment can overhaul after being effectively realized isolation by technical measures or means again, but, relay protection and the quarantine measures of automaton screen cabinet in secondary device particularly secondary device are but perfect not.The typical representative structure of relay protection and automaton screen cabinet is as depicted in figs. 1 and 2.This screen cabinet sets 6 set protection devices altogether and shields layout altogether, and screen is cashier's office in a shop provided with the parts such as some button 5a, air switch 4a, terminal block 3a, pressing plate 6a.Owing to there are some contacts by wire between each device; to realize certain control defencive function; therefore; operating device can be produced impact to by the simulation test of checking device by maintenance process, easily make operating error action of device make, therefore; need to remove by the contact loop between checking device and running gear before maintenance; but if split the end of a thread or line nose are exposed outside, then the personnel that are easily caused touch by mistake, error action of device, it is therefore desirable to reliably isolate；
The terminal block 3a effect for being connected with the loop of screen cabinet external equipment to transmit signal by equipment in screen cabinet.Owing to the terminal in terminal block is more; for preventing from the operating loop that maintenance mistiming is touched in terminal block from causing false protection and staff to tear open, take operating loop causing the problems such as false protection by mistake by mistake, thus need before maintenance the terminal block of running gear to be isolated and substantially indicate；
Screen air switch cashier's office in a shop is used for controlling often set and protects the control power supply of device, operation power supply, and owing to common screen is arranged, each air switch overlapping protection device arranges closely, is easily caused staff and divides by mistake, close air switch by mistake during maintenance.Even if the air switch of single layout, also needing to prevent maloperation, therefore, during maintenance, air switch keeps correct status to be particularly important；
Screen button 5a cashier's office in a shop be human users, control protective unit running status, action logic realize element.Owing to being switch element, during maintenance, Yi Fashengyin touches the misoperation causing device by mistake, thus needs to take safeguard procedures to button 5a；
Screen pressing plate cashier's office in a shop is also named protection in flakes, is bridge and the tie of protection device contact external wiring, and can the function and the action outlet that be related to protection normally play a role, and common pressing plate has 2 kinds of structures, respectively the first pressing plate 6a and the second pressing plate 7a.Pressing plate is installed concentratedly in screen bottom, densely distributed, Various Functions, and the accident caused because of miscarrying, by mistake bruising plate when maintenance is of common occurrence, therefore, before maintenance, it is necessary to relevant protection pressing plate is taked safeguard procedures, stops accident and occurs.
Generally, in the protection indoor of same transformer station, multiaspect sealer cabinet all can be installed；On the same face sealer; it is commonly installed many set protection devices; therefore during maintenance staff easily because running wrong screen position, admit one's mistake device and the protection device that is in operation work; thus directly resulting in the generation of accident; currently also see such preventer preventing from running wrong screen cabinet; if Authorization Notice No. is the Chinese patent literature of CN201682187U, disclose a kind of name and be called the alert curtain for station of " Extensible warning curtain ".
