Description
Technical field
The 10 KV distribution cabinets the invention belongs to electric power aid field, more particularly to a kind of utilization lever principle are isolated
Baffle plate opener.
Background technology
The nuclear phase that static contact in 10 KV distribution cabinets is carried out, pressure test, electrical verification etc. need to open isolation baffle plate, isolation
Baffle plate is driven by the isolation baffle plate mechanism in switch cubicle, so the isolation baffle plate mechanism in 10 KV distribution cabinets（Also known as valve machine
Structure）It is that skilled behaviour personnel clamp or rope fix the front end of valve mechanism lever to open a kind of open method, and is needed
Two people cooperate and could complete the folding of isolation baffle plate simultaneously, the use of conventional method is operating personnel and electrical body it is difficult to ensure that
Safe enough distance（0.35 meter of 10kv safe distances）And unlatching quality cannot be ensured, may isolate when staff works
Baffle plate is closed suddenly, and danger is brought to staff.
In addition, have after some opening devices are the trolley base transformation in switch, for opening isolation baffle plate, but this
A little improved trolley base structures are larger, the constructing operation that the personnel that hinder one's work enter in cabinet, and its reliability is not yet
Stabilization.
The content of the invention
10 kilovolts of a kind of utilization lever principle invented it is an object of the invention to overcome deficiency of the prior art

The present invention has advantages below：
Isolation baffle plate mechanism in 10 KV distribution cabinets is located at left and right sidewall both sides in cabinet, has inwardly projecting in its structure
Axle wheel, so that dolly can open isolation baffle plate by promoting shaft-like protrusion in 10 KV distribution cabinets.The present apparatus
First lasso and the second lasso are enclosed within the axle wheel of isolation baffle plate mechanism, are then pressed downward its body, and now device is with second
Lasso drives the first connecting shaft, pull bar and the first lasso to move downward as quiet fulcrum, and then drives valve mechanism motion, from
And the upper isolation baffle plate in isolation baffle plate is opened, now the first lasso is changed into quiet fulcrum, continues to push its body, with first set
Enclose for quiet fulcrum extrude the motion of the second lasso in place when so that lower isolation baffle plate in isolation baffle plate is opened, i.e. the first lasso and
In the different phase quiet fulcrum each other of motion process, the angle between the first lasso and the second lasso diminishes second lasso,
Beginning counteresteer effect between ratchet, ratchet during this, when acting under pressure downward on its body cancels at any time
In the case of, remains stationary between package unit and isolation baffle plate mechanism, isolation baffle plate by restoring force effect and involution.Close
During isolation baffle plate, pressing ratchet unblock pressing plate, ratchet unblock can be rotated backward, and release the locking to isolation baffle plate mechanism, returned
Isolation baffle plate mechanism involution in the presence of multiple power, upper and lower isolation baffle plate is closed.
It is present apparatus clever structure, easy to use, it is not necessary to which that user has abundant use experience just operable, in addition, thick stick
The length of bar body can easily be manufactured into and meet safety requirements.
Other present apparatus compact, with fixed locking function, will not take space in excessive cabinet, convenient work people
Member works in cabinet.
