Description
Technical field
The present invention relates to electric system switchgear technical field more particularly to a kind of armours for facilitating verification switchgear phase sequence
Fill the strqw cover open-and-close mechanism and method of withdraw-type AC metal closed switch cabinet.
Background technique
Power industry and the most common switch form of industry 10kV voltage class are middle switch, are usually moved with armouring
Open type AC metal closed switch cabinet (hereinafter referred to as switchgear) matches.In newly installation switchgear, by electrical cables replacement etc.
In many situations, need to verify phase sequence at the upper and lower static contact in switchgear to determine whether power supply can be used normally.School
The upper and lower strqw cover for blocking static contact in switchgear need to be opened when testing phase sequence operation, expose static contact, then carried out with to phase pen
Verify phase sequence.
Existing switchgear strqw cover open-and-close mechanism is lever mechanism, needs operator deeply to switch when opening strqw cover
It in cabinet, and needs to push lever mechanism with compared with great strength, since this operation is very close away from band electrical contact distance, accidentally just hold
Electric shock accidents or equipment short circuit accident are easily caused, therefore there are great security risks.
Summary of the invention
The present invention provides the strqw cover open-and-close mechanisms and method of a kind of clad withdrawal-type AC metal-enclosed switch cabinet, normally
Pass through switch vehicle triggering when operation and open strqw cover, the folding that operator can be easily accomplished strqw cover outside cabinet when verifying phase sequence is moved
Make, structure is simple, flexible and convenient operation, and high safety, labor intensity are low.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
The strqw cover opening/closing method of clad withdrawal-type AC metal-enclosed switch cabinet is closed based on armored moving alternating-current metal
The strqw cover open-and-close mechanism of switchgear realizes that the strqw cover open-and-close mechanism of the clad withdrawal-type AC metal-enclosed switch cabinet includes upper
Portion's trigger mechanism, lower part trigger mechanism and triggering block；Top trigger mechanism and lower part trigger mechanism are separately mounted in switchgear
Two side walls on, include multiple pulleys, wirerope and trigger；Wirerope one end in the trigger mechanism of top with it is corresponding on
The top of strqw cover connects, and the other end connects trigger after bypassing corresponding pulley；Wirerope one end in the trigger mechanism of lower part with it is right
The top of strqw cover should be played to connect, the other end connects trigger after bypassing corresponding pulley；Trigger is by being mounted on the touching switched on vehicle
It sends out block or artificial triggering, wirerope drive upper and lower strqw cover to realize opening and closing movement after being pulled；
The trigger is fixed on the middle part of switchgear two sidewalls, by fixed baffle, the spring set gradually from inside to outside
It is formed with moving stop；Guide rod is set between fixed baffle and moving stop, the outside of moving stop is connected with wirerope one end；
Moving stop is correspondingly arranged with the triggering block on switch vehicle, and moving stop can be after compressed spring along leading under the stirring of triggering block
It is mobile to bar to fixed baffle side.
The top trigger mechanism is by being arranged in the pulley blocks one, wirerope one and trigger one on switchgear two sidewalls top
Composition；First pulley in pulley blocks one is arranged above upper strqw cover, second pulley is arranged in switchgear top side wall interposition
It sets, the 4th pulley is arranged on the outside of trigger；Third pulley is arranged in second pulley horizontal axis and the 4th pulley vertical axis
The place that intersects vertically；
The lower part trigger mechanism is by being arranged in the pulley blocks two, wirerope two and trigger two of switchgear two sidewalls lower part
Composition；First pulley in pulley blocks two is arranged above lower strqw cover, second pulley is arranged in switchgear sidewall bottom interposition
It sets, the setting of the 4th pulley is arranged in trigger outer lower side, third pulley in second pulley horizontal axis and the 4th pulley vertical axes
The place that intersects vertically of line；The interior lower section of trigger is arranged in 5th pulley.
The strqw cover opening/closing method of the clad withdrawal-type AC metal-enclosed switch cabinet includes the following steps:
1) fixed at the top of one end of the wirerope one in the trigger mechanism of top and upper strqw cover to connect when switchgear normal use
It connects, the other end connects the shifting for corresponding to trigger after successively bypassing first pulley, second pulley and the 4th pulley in pulley blocks one
Dynamic baffle；
As switch vehicle shakes from test position to working position, the triggering block switched on vehicle is mobile to switchgear side, dials simultaneously
Moving stop in dynamic top trigger mechanism trigger one and lower part trigger mechanism trigger two；2 moving stops are along correspondence
Guide rod is mobile to corresponding fixed baffle side, and drives wirerope one to be pulled upwardly strqw cover respectively, drives wirerope two
Lower strqw cover is discharged downwards；Static contact after upper and lower strqw cover exposes to be engaged with the moving contact on switch vehicle；
2) when needing to carry out switchgear verification phase sequence operation, switch vehicle is pulled out outside switchgear, trigger one and trigger
Spring-return in two is in situ, and upper and lower strqw cover, which closes, shelters from static contact；At this time manually by the wirerope one of top trigger mechanism
Then around to the wirerope one on corresponding third pulley, since the path that wirerope one bypasses is elongated, with the fixed one end of upper strqw cover
It will shrink upwards, so that upper strqw cover be driven to be pulled upwardly；Then again manually by the wirerope two in the trigger mechanism of lower part from correspondence
Third pulley on unload, since the path that wirerope two bypasses shortens, stretched downwards with the wirerope two of the fixed one end of lower strqw cover
It is long, discharge lower strqw cover downwards, upper and lower strqw cover exposes static contact after opening, and facilitates and carries out verification phase sequence operation；
3) after the completion of examining phase sequence operation, by the wirerope one in the trigger mechanism of top again from corresponding third pulley
It removes, the wirerope two in the trigger mechanism of lower part is hung over again on corresponding third pulley；Switchgear, which can be put into, normally to be made
With.
Compared with prior art, the beneficial effects of the present invention are:
1) it can satisfy switchgear normal use, guarantee to realize that strqw cover blocks band electrical contact, switch vehicle when switch vehicle pulls out
Shake the basic function into the occlusion of rear dynamic/static contact；
2) convenience when verification phase sequence is substantially increased；Only it need to can be achieved with covering in switchgear external-adjuster wirerope position
The movement of curtain folding eliminates operator and enters security risk caused by operation in cabinet.
