Description
Technical field: the utility model belongs to the electromagnetic lock that high voltage switchgear equipment is used, particularly a kind of electromagnetic lock that prevents that misoperation of high-pressure switchgear from using.
Background technology: documents 1 is the patent application case of publication number CN101538959, discloses the safety electric magnetic padlock that a kind of high voltage switchgear equipment is used.It is characterized in that in casing, being equiped with lock bolt components, electromagnetic locking mechanism, mechanical jam plate and travel switch respectively, be respectively arranged with emergency release button, jam plate unlock hole and locking bolt handle and charged indicator lamp, misunderstanding lock indicator lamp on the cabinet panel.Its technical operation scheme is that " charged indicator lamp is bright, shows that electromagnetic lock is charged, does not allow release, and at this moment, even stir handgrip, the activity locking bolt of also not opening is even use private key also can't open; If charged indicator lamp does not work, show that electromagnetic lock is not charged, lock allows to open, at this moment, and in the unlock key insertion keyhole with special use, drive mechanical jam plate by key, the jam plate that mechanical jam plate is left on the movable locking bolt limits, and stirs handgrip then, and movable locking bolt is opened, when movable locking bolt retreats into the limit, can be automatically locked at lockset position of coupler; The effect of misreading the lock indicator lamp is, if electromagnetic lock is charged, when electromagnetic lock inserted key, key was directly pushed down travel switch, and it often makes war closed, misreads the lock indicator lamp and lights, and shows lock also at electriferous state, should stop unlocking operation at once.”
To the operation of high voltage switchgear equipment, must just can reach: prevent mistake drawing switch, prevent on-load drawing isolation switch, prevent mistakenly entering charged chamber, prevent charged hanging ground-wire, prevent " five is anti-" requirement of switching on earth wire in strict accordance with the safety operation program of industry regulation.And the electromagnetic lock that existing various high voltage switchgear equipment is used adapts to this code requirement just, with cooperating of the frame for movement of lockset and key, forcibly make the operating personnel can only be, thereby guarantee the enforcement that " five is anti-" requires according to set procedure operation high voltage switchgear equipment.
Electromagnetic lock safety operation program according to the industry regulation: the indicator lamp on the electromagnetic lock panel is bright, show that high voltage switchgear equipment such as high-tension switch cabinet stop normal operation, there is not high-tension electricity in the high voltage switchgear equipment, opening the cabinet door as need carries out the operation that " five anti-" require and satisfies the requirements, operating personnel are when carrying out unlock operation, press its upper end of core bar of unblanking earlier, promptly press the button, be fixed in its middle part fan-shaped pressing board press down thereupon travel switch the switch push rod, travel switch is connected the electric current through electromagnet coil, electromagnet coil produces electromagnetic force, with the electromagnet cylinder adhesive of electromagnet front assembly on the electromagnetic actuation body of electromagnet rear assembly, after the electromagnet cylinder that moves drive the fore-set that is fixed in its center, the fore-set front end moves behind the spacing rank of movable locking bolt neck near the electromagnetic lock assembly, and movable locking bolt is not lockable; Swing handle, the core bar cover that is fixed on the handle rotates thereupon, is positioned at the driving lever of stirring groove that core bar cover bottom, its end snap in movable locking bolt and also rotates thereupon, moves after ordering about movable locking bolt, and electromagnetic lock is opened smoothly.Indicator lamp on the electromagnetic lock panel is not bright, show that high voltage switchgear equipment such as high-tension switch cabinet normally move, have high-tension electricity in the high voltage switchgear equipment, do not possess and carry out the operating condition that " five is anti-" requires, the operator can't open high-tension switch cabinet cabinet door, thereby has guaranteed the practical enforcement that " five is anti-" requires forcibly; Open the cabinet door as need and overhaul, the maintainer must enable the unlock key that upper management person just holds, and could open the cabinet door by the electromagnetic lock unlock assembly.
The electromagnetic lock safety operation program of contrast industry regulation, the technical operation scheme of document 1 have been run counter to conventional " five is anti-" requirement, will inevitably mislead operating personnel, stay the hidden danger of maloperation, even may lead to a disaster.Moreover still the electromagnetic lock safety operation program of industry regulation is not unallowed to misread the setting of locking indicator lamp, but also has increased the complexity of structure, the increase of manufacturing cost, the decline of operational reliability.This shows that design and a kind of meeting " five anti-" require, the electromagnetic lock that misoperation of high-pressure switchgear is used from being necessary in rational in infrastructure, reliable preventing.
