Description
Technical field
The utility model relates to a kind of interlocking mechanism more particularly to a kind of interlocking mechanisms for KYN61 switchgear.
Background technique
KYN61-40.5 type indoor high-voltage vacuum switchgear system three-phase alternating current 50Hz, voltage rating 40.5kV it is indoor complete
Power distribution equipment is to receive and distribute electric energy as power plant, substation and industrial and mining enterprises to be used, plays control, protection to circuit
With detection etc. functions.With the development of industry, production technology continuously improve and the raising of production technology, domestic KYN61
Cabinet body has no longer adapted to the requirement of client.And vacuum circuit breaker (ZN85-40.5) and earthing switch in novel KYN61 cabinet body
(JN22-40.5) operating mechanism is mechanical interlocked, is usually deformed using original interlocking mechanism, cannot achieve mechanical mutual
Lock, " five is anti-" not being able to satisfy in national standard require.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a kind of interlockings for KYN61 switchgear
Mechanism increases intensity, realizes the mechanical interlocked of vacuum circuit breaker and earthing switch operating mechanism.
To achieve the above object, the utility model is achieved through the following technical solutions:
A kind of interlocking mechanism for KYN61 switchgear, including bent plate, pressing plate, spacer, bent plate top and earthing switch are grasped
Make mechanism connection, bent plate lower part is longitudinally equipped with slotted hole, and bent plate side is equipped with pressing plate, and the other side is equipped with side cabinet, cabinet body side
Plate, spacer, pressing plate are bolted to connection, every being set in slotted hole.
The bolt is square neck bolt.
The bent plate lower part is bent into for double-layer plate.
Compared with prior art, the utility model has the beneficial effects that
Interlocking mechanism for KYN61 switchgear may be implemented in functional loop, between vacuum circuit breaker and earthing switch
Mechanical interlocked relationship；Overall structure is simple, easy for installation, simple and direct reliable.It is limited using the slotted hole on spacer and bent plate
The extreme position of bent plate.Below bent plate, the vacuum circuit interrupter grounding interlocking mechanism on side cabinet cooperates, real for bent plate and setting
It is mechanical interlocked between existing vacuum circuit breaker and earthing switch.The transverse direction that the setting of pressing plate can limit bent plate lower part is thrown, is guaranteed
Bent plate stablizes movement.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification, it should be noted that the utility model
Implement embodiment not limited to the following.
See that Fig. 1-Fig. 6, a kind of interlocking mechanism for KYN61 switchgear, including bent plate 3, pressing plate 2, spacer 5, bent plate 3 push up
End is connect with earthing switch operating mechanism 7, and 3 lower part of bent plate is longitudinally equipped with slotted hole, and 3 side of bent plate is equipped with pressing plate 2, the other side
Equipped with side cabinet 4, side cabinet 4, spacer 5, pressing plate 2 are fixedly connected by bolt 6, and spacer 5 is arranged in slotted hole, bent plate
3 limit the extreme position to move up and down, left and right transverse shifting of the pressing plate 2 to limit bent plate 3 by spacer 5 (see Fig. 1).
Wherein, bolt 6 is square neck bolt 6, to facilitate positioning, and prevents bolt 6 from throwing.Bent plate 3 is moved up and down to block and be connect
Ground switchs handle hole and vacuum circuit interrupter grounding interlocks hole, and limits bent plate 3 using spacer 5, pressing plate 2 and can only move up and down.It is curved
3 lower part of plate is bent into for double-layer plate, to increase by 3 bottom end intensity of bent plate, prevents bent plate 3 after multi-pass operation from deforming, Jin Erzao
It can not be retracted at vacuum circuit interrupter grounding interlocking mechanism 1.
See Fig. 1, Fig. 2, when earthing switch is in gate-dividing state, vacuum circuit breaker is in operating position, earthing switch interlocking dress
It sets in interlocking position, bent plate 3 can not reach lower position by pressure, and the operation handle of earthing switch operating mechanism 7 can not
Insertion, so earthing switch can not close a floodgate.Fig. 5, Fig. 6 are seen, when vacuum circuit breaker is at testing position, ground switch interlocking device
In unlocked position, pushes bent plate 3 and reach lower position, be inserted into the operation handle of earthing switch operating mechanism 7, rotate clockwise
180 degree closes a floodgate earthing switch.Earthing switch operating mechanism 7 push down bent plate 3 can not uplink, bent plate 3 blocks vacuum circuit breaker
The interlocking hole of earthing switch interlocking mechanism, vacuum circuit breaker can not be advanced to operating position from testing position, reach vacuum circuit breaker
Interlocking effect between device and earthing switch.
