Embodiment
Below embodiments of the invention are described in detail:
As shown in Figures 1 to 9, in relay protection debugging and maintenance work, need the power-off of default loop, disconnecting pressure plate electrode interconnection switch, protective treatment must be carried out to the pressure plate electrode of charged side to prevent misoperation staff.The invention provides a kind of relaying protection and the anti-error gum cover 10 of automation pressing plate; comprise the insulating gum cover 100 with openend coordinated with pressure plate electrode; the insulating cap 200 installed is coordinated with gum cover 100 openend; block 200 has the block elongated portion 220 extending to the inner other end of gum cover 100, is provided with permanent magnet in block elongated portion 220.
By insulating gum cover 100 is linked on pressure plate electrode, and will insulation and the block 200 with permanent magnet is arranged on gum cover 100, permanent magnet adsorbs metal platen, whole relaying protection and the anti-error gum cover 10 of automation pressing plate are fixed, to realize carrying out protective treatment to the pressure plate electrode of charged side, prevent staff's misoperation in relay protection debugging and maintenance work, this protection mechanism is relative to winding insulating tape, install more that safe ready is flexibly and fast, also be not easy suffer the pollution of greasy dirt and dust and loosen landing, can also Reusability not cracky, outward appearance is also very attractive in appearance.And space between pressure plate electrode is very little, require that the volume of anti-error mechanism can not be too large, and anti-error mechanism and the fixed form of the metal decking of protection cabinet should to fix dynamics moderate, ensure that the insulation of anti-error mechanism and pressure plate electrode and metal decking is good again.The relaying protection designed for on-the-spot feature and the anti-error gum cover 10 of automation pressing plate can improve relay protection debugging and the security performance of maintenance work and operating efficiency, and can reuse, not only safe and reliable but also environmental protection practicality.
As shown in Figure 1 to Figure 3, insulating gum cover 100 comprises cylindric urceolus 110, and being set in the cylindric inner core 120 of urceolus 110 inside, urceolus 110 and inner core 110 one end link together, and form the shape that other end opening and the equal opening in inner core 120 two ends are closed in urceolus 120 one end.Inner core 120 can intactly be inserted in whole pressure plate electrode, uses binocular structure, isolates, make fail safe higher by between pressure plate electrode and urceolus, and protection mechanism also can be linked in difficult drop-off on pressure plate electrode more closely simultaneously.And, the cast that double-deck tubular gum cover adopts insulation property good, ensure its isolated insulation dependable performance, the interior diameter of inner core 120 will guarantee completely to be inserted in whole pressure plate electrode, the overall diameter of urceolus 110 is less than 1/2nd of adjacent two pressure plate electrode end air line distances, ensures to have between adjacent pressing plates electrode tip enough independence can operating space.In addition, urceolus 110 outer surface is arranged to ripple dentation, increases friction and is convenient to pick up not easily landing, too increase aesthetics.
Inner core 120 is in the eccentric position (i.e. inner core 120 and urceolus 110 decentraction) of urceolus 110 inside, when block 200 is arranged on gum cover 100, in the sleeve gap 130 of block elongated portion 220 between urceolus 110 and inner core 110.Make between inner core 120 and urceolus 110 more spacious in position on one side, convenient have enough space mounting block elongated portion 220 at sleeve gap 130 place.
Cap 200 also adopts the insulating material with double-deck tubular gum cover 100 same performance as shown in Figures 4 to 6, and size and structure will match with cylindric gum cover 100, ensure its integrality and sealing.Block 200 comprises block main body 210, and the block elongated portion 220 be connected with block main body 210.This block elongated portion 220 is column structure, and have the mounting groove 222 installing permanent magnet in block elongated portion 220, this hole slot is positioned at the end position of block elongated portion 220.Mounting groove 222 is set in block elongated portion 220, permanent magnet is installed and is embedded in this mounting groove 222, when block 200 is covered on gum cover 100, conveniently whole anti-error mechanism is adsorbed on pressing plate.Block elongated portion 220 can be various shape, and convenient cooperation with the sleeve gap 130 of gum cover 100 installs.Elongated portion 220 of herein preferably blocking a shot is cylindric, and cylindric easy manufacture is produced.A small column magnet is embedded in cylindric block elongated portion 220 interior cylindrical mounting groove 222; the volume of small column magnet will combine closely to ensure reliably to combine together between the two with mounting groove 222 in block elongated portion 220; this small column magnet should have the moderate magnetic performance of dynamics, ensure whole relaying protection and automation pressing plate anti-error gum cover 10 can solid and reliablely attached suction on the metal decking protecting cabinet.This block elongated portion 220 except be set to cylindric except, also can be arranged to flat column or irregularly shaped, such as, be arranged to the cylinder that cross section is circular arc, can more easily coordinate with the sleeve gap 130 of gum cover 100 install and install firm.According to the different profiles of block elongated portion 220, its inner mounting groove 222 installing permanent magnet can be set to corresponding shape.
Block main body 210 is provided with block groove 212, in block groove 212, indication plate 300 is installed.As shown in Figure 7, indication plate 300 is labeled with " in operation " or other similar text prompt, in addition, indication plate 300 also can marks the mark of associated companies.And indication plate 300 is arranged to blueness, and other parts of anti-error gum cover are arranged to redness, play obvious suggesting effect and to show difference.Indication plate 300 is fixed on the centre position of block main body 210, plays obvious reminding effect, prevents the situation carrying out operating in charged situation from occurring.Indication plate 300 is made by with gum cover 100 and 200 same insulating material of blocking a shot.Indication plate 300 can be arranged to square, arc-shaped or other shapes.
Relaying protection provided by the invention and the anti-error gum cover 10 of automation pressing plate, mainly comprise cap 200 and one piece of square indication plate 300 of a double-deck tubular gum cover 100, band cap elongated portion 220, the safety prevention measure of a pressure plate electrode terminal can be made to reduce to 0.5 second from 20 seconds, improve operating efficiency; In operating process, staff directly need not contact pressing plate, thus has stopped staff owing to carrying out this operation and the electric shock accidents that causes; The material insulation property making this anti-error mechanism is good, isolation effect is good, and reusable safe and environmentally friendly; Design unified standard, indicate clear eye-catching, flexible and convenient operation, improve normalization, reliability and operability.In a word, relaying protection provided by the invention and the anti-error gum cover of automation pressing plate, improve relay protection debugging and the security performance of maintenance work, improve operating efficiency, and can reuse, dependable performance, easy to operate, safe and environmentally friendly, practical.
The above embodiment only have expressed the specific embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
