Description
Technical field
The invention belongs to electric power aid field, particularly relate to a kind of 10 KV distribution cabinet isolation baffle plate openers utilizing lever principle.
Background technology
The nuclear phase that fixed contact in 10 KV distribution cabinets carries out, withstand voltage test, electrical verifications etc. need to open isolation baffle plate, isolation baffle plate is driven by the isolation baffle mechanism in switch cubicle, so it is the front end that valve mechanism lever fixed by skilled behaviour personnel clamp or rope that the isolation baffle mechanism (also known as valve mechanism) in 10 KV distribution cabinets opens a kind of open method, and need two people to cooperatively interact simultaneously and just can complete the folding isolating baffle plate, conventional method is used to be that operating personnel and electrified body are difficult to ensure safe enough distance (10kv safe distance 0.35 meter) and open quality to ensure, may when staff works, isolation baffle plate closes suddenly, danger is brought to staff.
In addition, have after some opening devices are the trolley base transformation in switch, be used for opening isolation baffle plate, but these improved trolley base structures are comparatively large, the personnel of hindering one's work enter the constructing operation in cabinet, and its reliability is also unstable.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art and a kind of 10 KV distribution cabinets isolation baffle plate openers utilizing lever principle of inventing.
The present invention is achieved in that a kind of 10 KV distribution cabinet isolation baffle plate openers, it is characterized in that: comprise its body, one end of its body is provided with the ratchet storehouse of hollow circular, an end face in ratchet storehouse is open surface, another end face in ratchet storehouse is provided with ratchet rotating shaft hole, the other end of its body is provided with and unlocks pressing plate storehouse, cylindric ratchet spring storehouse is provided with in its body of side, ratchet storehouse, the cylindric bracing wire storehouse of both UNICOMs is provided with in its body between ratchet spring storehouse and unblock pressing plate storehouse, the diameter in bracing wire storehouse is less than the diameter in ratchet spring storehouse, ratchet is provided with ratchet in storehouse, the open end face in ratchet storehouse is provided with ratchet cover plate, ratchet rotating shaft reaches outside ratchet storehouse by ratchet rotating shaft hole, ratchet rotating shaft is provided with the first connecting axle, the other end of the first connecting axle is provided with pull bar, the other end of pull bar is provided with the first lasso, first connecting axle, first lasso and pull bar are all threaded connection, ratchet and spring is provided with in described ratchet spring storehouse, the head of ratchet contacts with ratchet, the afterbody of ratchet is connected with one end of spring, the other end of spring contacts with the end face in bracing wire storehouse, bracing wire is provided with bracing wire in storehouse, one end of bracing wire is connected with the afterbody of ratchet, the other end of bracing wire extends to and unlocks in pressing plate storehouse, unlock in pressing plate storehouse and be provided with unblock pressing plate, described unblock pressing plate is fixed on by axle and unlocks pressing plate storehouse, and can rotate in unblock pressing plate storehouse, the part unlocking pressing plate reaches and unlocks outside pressing plate storehouse, bracing wire is connected with the unblock pressing plate unlocked in pressing plate storehouse, the outer setting of its body has the second lasso.
One end of the first described lasso is screw rod, and screw rod is connected with pull bar, and the other end of screw rod is annulus, the second described lasso comprises base, base is connected with lever outer wall, and base is set to annulus, and the annulus axis of the first lasso and the second lasso is parallel to each other.
Described its body and unblock pressing plate outer surface are provided with insulating coating.
The present invention has the following advantages:
Isolation baffle mechanism in 10 KV distribution cabinets is positioned at sidewall both sides, cabinet left and right, oriented interior outstanding arbor wheel in its structure, so that dolly can make isolation baffle plate open by promoting shaft-like protrusion in 10 KV distribution cabinets.First lasso of this device and the second lasso are enclosed within the arbor wheel of isolation baffle mechanism, then to pressing down its body, this timer is using the second lasso as quiet fulcrum, drive the first connecting axle, pull bar and the first lasso move downward, and then drive valve mechanism motion, thus the upper isolation baffle plate opened in isolation baffle plate, now the first lasso becomes quiet fulcrum, continue depress lever body, with the first lasso be quiet fulcrum extrude second lasso motion put in place time, the lower isolation baffle plate of isolating in baffle plate is opened, namely the first lasso and the second lasso are at the different phase quiet fulcrum each other of motion process, first lasso and the second lasso angle each other diminish, ratchet in this process, to begin between ratchet counteresteer effect, when act on pressure downward on its body cancel at any time under when, keep static between package unit and isolation baffle mechanism, the not involution by the effect of restoring force of isolation baffle plate.When closing isolation baffle plate, pressing ratchet unlocks pressing plate, and ratchet unlocks and can rotate backward, and removes the locking to isolation baffle mechanism, isolates baffle mechanism involution, isolate flapper closure up and down under the effect of restoring force.
This apparatus structure is ingenious, easy to use, does not need user to have abundant use experience just can operate, and in addition, the length of its body can manufacture easily and meet safety requirements.
This device volume is small and exquisite in addition, has fixing locking function, can not take space in too much cabinet, facilitates staff to work in cabinet.
