Description
Technical field
The invention belongs to switching technique field, more particularly, to electric switch technology, specifically one kind are opened for electrical equipment
The earthed switch of pass equipment and its method.
Background technology
Earthed switch be a kind of for by a kind of machinery of equipment or line-to-ground, in exception conditions, such as
When short-circuit, carry the abnormal current of regulation at the appointed time, in case in equipment or line maintenance it is ensured that the peace of maintainer
Entirely.Earthed switch is more common in the controller switching equipments such as High-low voltage switch cabinet, main include static contact and movable touch knife, in both one with
Equipment is connected, and another one is grounded.For common switch cabinet, each three of the dynamic/static contact of earthed switch, three static contacts divide
Do not connect the end of incoming cables bus of switch cubicle, three movable touch knifes are matched one by one with static contact respectively, ground connection is arranged by line.
Described static contact is fixed on base by insulator, and movable touch knife is assemblied on a main shaft, coaxial with movable touch knife
Fixing assembling has connecting lever, the movable end of connecting lever and movable touch knife stage clip（The cylindrical compression spring of two ends door assembly with hinge and glass in right hand and left formula union joint）Connect
Hinged.The critical point of connecting lever and stage clip is closed a floodgate and gate-dividing state between movable touch knife.Under gate-dividing state, stage clip acts on
Moment of torsion on main shaft is contrary with combined floodgate, and this action torque is maintained movable touch knife under gate-dividing state with position-limit mechanism cooperation.To master
Axle applies external force, and to combined floodgate direction live spindle, connecting lever compression press spring energy storage, when the critical point turning over stage clip, stage clip acts on
Torque conversion direction on main shaft, releases energy rapidly, and promotes connecting lever to assist combined floodgate external force to drive movable touch knife rapid closing；Instead
It, under "on" position, stage clip acts on the torque conversion direction on main shaft, and this action torque and position-limit mechanism cooperation will be moved tactile
Knife maintains under "on" position.Main shaft is applied with external force so as to rotate to separating brake direction, connecting lever compression press spring energy storage, when turning over
The critical point of stage clip, the torque that stage clip acts on main shaft is changed direction again, and stage clip promotes connecting lever to assist separating brake external force to enter one
Step drives movable touch knife to rotate to separating brake direction, and until limited means block, separating brake process completes.
Described earthed switch three-level independence subpackage, often extremely mainly has CJ11 type motor-operating mechanism, action bars, insulator bottom
A few part composition such as seat, support insulator, ground connection conducting loop sytem.Every pole earthed switch is respectively grasped with a CJ11 motor drive mechanism
Dynamic.Three-level earthed switch can carry out three-phase electric apparatus combined operation.The motor process of earthing is to be formed by two parts motion synthesis,
I.e. folding movement and insertion motion.Folding movement has CJ11 type motor drive mechanism to drive action bars and active connecting lever to horizontally rotate, and leads to
Cross a set of excessive levels double leval jib transmission on insulator foot, the rotational angle of mechanism is transformed into 120 degree by 180 degree, mistake
Degree connecting lever is driven with a set of space four-linkses of passive connecting lever composition on earthing base, and the horizontal direction of excessive connecting lever is rotated
The vertical direction being transformed into passive connecting lever rotates, and rotational angle is transformed into 90 degree by 120 degree, and drives earthing down tube to do vertically
Rotary motion carries out divide-shut brake.Action bars one end in earthing down tube is hinged with earthing base, and one end is connected with tooth bar.By
Different with base pin joint position from base pin joint and earthing down tube in action bars, in the vertical rotary course of earthing down tube
In, action bars axially moves with respect to down tube, and the axial movement of such tooth bar just promotes gear to rotate, so that with gear even
On the earthing connecing, pipe stretches or folding movement with respect to earthing down tube, thus completing the separating brake of earthing or closing a floodgate dynamic
Make.In addition, while action bars axial displacement, balancing spring by predetermined requirement energy storage or releases energy, balances to greatest extent
The gravitational moment of ground connection knife bar, is beneficial to the motion of ground connection knife bar.Insertion motion is ground connection knife bar from open position to closing position
During motion, when close to closing position, moving contact can be gradually inserted static contact along the horn cover inwall of static contact
Internal.Because moving contact is bar type structure, static contact fingertip is plum-shaped structure, and moving contact can slowly touch spreading plum-shaped structure
Refer to, insertion fingertip is internal to be completed to close a floodgate with fingertip.
Described motor-operating mechanism passes through the operating of the rotation driven gear of two-stage gear, sets on the main shaft of earthed switch
Put an oilless bearing, then provide support in an axle sleeve installed above for driving gear.When driving gear carries out certain angle
Rotation after, the boss on the gear left side will be produced with main shaft drives part and contact, thus driving main shaft drives part to operate, because leading
Shaft driver is directly connected to operation axis, and when actuator occurs operating, main shaft also can follow run-in synchronism.Run to
When to a certain degree, earthed switch starts action, this be main shaft drives part running speed faster than the movement velocity of driving gear,
But, because driving boss to have enough spaces, ensure that driving gear and main shaft drives part in work
As when be independent of each other, and keep the self-movement of persistence.After receiving earthed switch actuating signal, driving gear returns to original
Position, to ensure, in manual operation, main shaft drives part and driving gear will not be made to influence each other, makes whole mechanism be able to mutually
Smoothly operate.
A kind of described Medium Voltage Switchgear earthed switch and front lower door interlocking mechanism.It includes ground switch rotating shaft, door body frame
It is provided with locking part on door inside frame, ground switch rotating shaft fixedly mounts an earthed switch axle sleeve, on earthed switch axle sleeve
The positive opposite house of projection on locking part groove location；Back-up ring on one earthed switch axle is provided with ground switch rotating shaft, ground connection
On switch shaft, the lower section of back-up ring is hinged with an earthed switch dead bolt, and earthed switch dead bolt upper end is provided with fastening end, and ground connection is opened
The front closing dead bolt is provided with push-botton operation axle on a door, and on door, push-botton operation the tip of the axis is pressed over earthed switch dead bolt
Lower end.Using after above-mentioned structure, it is achieved that working as grounding switch tripping, when chopper is in operating position, front Xiamen should
Open；After only pressing push-botton operation axle on Xiamen, earthed switch could close a floodgate, and after earthed switch closes a floodgate, front Xiamen just can be beaten
Open the safety it is ensured that operator, it is to avoid the generation of peril.
At present, the disclosed multiple earthed switches of existing technology, but these earthed switches have only played it as connecing
The effect of ground switch, thunder and lightning is that sound in an atmosphere, light, electric physical phenomenon occur, and is nature air the most grand and important
One of phenomenon, thus current earthed switch only play itself effect also far from enough, there is its weak point.It is provided simultaneously with
