Description
Technical field
The invention belongs to electromagnetic lock parts and the manufacture method thereof of high voltage switchgear equipment, particularly a kind of high voltage switchgear equipment electromagnetic lock housing and manufacture method thereof.
Background technology
To the operation of high voltage switchgear equipment, the safe handling procedures that must specify in strict accordance with industry just can reach: " five prevent " requirement of the switching on earth wire that prevents missing drawing switch, prevents on-load drawing isolation switch, prevents mistakenly entering charged chamber, prevents live ground wiring, prevents.And the electromagnetic lock of existing various high voltage switchgear equipment adapts to this code requirement just, with coordinating of the frame for movement of lockset and key, forcibly make operating personnel according to set procedure operation high voltage switchgear equipment, thus the enforcement that " five prevent " requires can only be guaranteed.
Document 1 is the patent application case of application number 201010197358.x, discloses a kind of electromagnetic lock preventing misoperation of high-pressure switchgear.The electromagnetic lock safe handling procedures specified according to industry: when the indicator lamp on electromagnetic lock panel is bright, show that high voltage switchgear equipment such as high-tension switch cabinet stops normal operation, high-tension electricity is not had in high voltage switchgear equipment, open cabinet door to carry out the operation that " five prevent " require and satisfy the requirements, operating personnel are when carrying out unlock operation, first press its upper end of core bar of unblanking, namely press the button, the fan-shaped pressing board be fixed in the middle part of it presses down the switch plunger of travel switch thereupon, the electric current through electromagnet coil connected by travel switch, electromagnet coil produces electromagnetic force, the electromagnet cylinder of electromagnet front assembly is pulled on the electromagnetic actuation body of electromagnet rear assembly, after the electromagnet cylinder that moves drive the fore-set being fixed on its center, fore-set front end is moved from movable locking bolt neck near behind the spacing rank of electromagnetic lock component, movable locking bolt is not lockable, swing handle, the core bar cover be fixed on handle rotates thereupon, and be positioned at the driving lever stirring groove that core bar overlaps bottom, its end snaps in movable locking bolt and also rotate thereupon, move after ordering about movable locking bolt, electromagnetic lock is opened smoothly.When the indicator lamp on electromagnetic lock panel is not bright, show that high voltage switchgear equipment such as high-tension switch cabinet normally runs, with high-tension electricity in high voltage switchgear equipment, do not possess the operating condition of carrying out " five prevent " and requiring, operator cannot open high-voltage switch cabinet door, thus ensure that the practical enforcement that " five prevent " requires forcibly; Overhaul as opened cabinet door, maintainer must enable the unlock key that upper management person just holds, and just opens cabinet door by electromagnetic lock unlock assembly.
High voltage switchgear equipment electromagnetic lock panel is designed with indicator lamp display window, unlock key hole, assembly grip hole of unblanking; The lock housing body internal upper part of the high voltage switchgear equipment electromagnetic lock of L.H.flapped door is designed with the active lock bolt assembly of forward and backward end through lock housing body sidewall, lower left quarter in lock housing body, be designed with the electromagnet assembly being matched with active lock bolt assembly, right lower quadrant in lock housing body, be designed with the travel switch being matched with electromagnet assembly, middle part in lock housing body, be designed with the assembly of unblanking being matched with travel switch and active lock bolt assembly, in lock housing body on active lock bolt assembly, be designed with unlock component near back side of panel; Internal component position in the lock housing body of the high voltage switchgear equipment electromagnetic lock of R.H.flapped door configures therewith axisymmetricly.
Existing high voltage switchgear equipment electromagnetic lock housing, first shaping through allumen casting operation, and then on the bottom surface and wall of housing, adopt bore process to process 10 of at least 4 kinds of different pore sizes through 5 procedures to use hole.Exist following not enough in actual use:
1, owing to adopting shaping, the metal working process of casting process to get out 10 of 4 kinds of different pore sizes with hole on 5 faces, operation is numerous and diverse and number of channels is many, and operation requirements is high, not only adds manufacturing cost, and have impact on product qualified rate.
2 just because of adopt the use hole on bore process processing housing, be difficult to process spacious reasonably rectangular electric wiring windows, directly affects convenience and the speed of subsequent installation operation, cause electromagnet front and rear portions assembly and be matched with electromagnet assembly travel switch installation and perforation lead-in wire carry out electrical connection seem difficulty.
3, housing adopts price high and the aluminium alloy material manufacture risen steadily, and causes the cost of the electromagnetic lock of high voltage switchgear equipment constantly to rise.
As can be seen here, study and design a kind of operation letter less, product qualified rate is high, the high voltage switchgear equipment electromagnetic lock housing that manufacturing cost significantly reduces and manufacture method thereof are necessary.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, design a kind of operation letter less, product qualified rate is high, the high voltage switchgear equipment electromagnetic lock housing that manufacturing cost significantly reduces and manufacture method thereof.
The present invention seeks to realize like this:
