Specific embodiment
To make those of ordinary skill in the art that the purpose of this utility model, technical solution and excellent be more clearly understood
Point is further elaborated the utility model below in conjunction with drawings and examples.
As depicted in figs. 1 and 2, a kind of ring main unit of embodiment includes a ring main unit body 10, one arranged on ring main unit sheet
Cabinet door 11, one on body 10 is located at the earthing switch handle hole 12, one above cabinet door and is located at connecing in earthing switch handle hole 12
Ground driving mechanism for switches (not shown), one by earthing switch driving mechanisms control earthing switch (not shown), one with behaviour
Make the mating 13 and one linkage earthing switch of earthing switch operation handle of earthing switch handle hole 12 with and cabinet door 11 the couplet on the door
Locking device 20.
Door interlock 20 includes a ground connection to door interlocking mechanism 21 and one to shutter interlocking mechanism 22.
It is grounded to door interlocking mechanism 21 and includes a vertical output shaft 211, a connecting lever 212 and a door bolt 213, wherein,
The vertical output shaft 211 links with earthing switch driving mechanism, which is rotatably arranged at vertical output shaft by axis pin
211 lower sections, its one end and the lower end of the vertical output shaft 211 are hinged, and the other end and the door bolt 213 laterally set are hinged, when
When vertical output shaft 211 is grounded driving mechanism for switches driving and longitudinal movement occurs, can door bolt be driven by connecting lever 212
213 transverse movements, the inside of cabinet door 11 be equipped with a door bolt hole 111 coordinate the door bolt 213 into and out.
11 inside of cabinet door is additionally provided with three hooks 112, is accordingly provided with what is hooked for hook 112 on ring main unit body 10
Transverse axis 113, when cabinet door 11 is closed, hook 112 is hooked in transverse axis 113, and must move up cabinet door 11 can make extension
112 solution of hook is hung on transverse axis 113, and when 213 transverse movement of door bolt corresponds to and can be realized to cabinet door 11 into and out door bolt hole 111
The locking of vertical and straight movement, in this way, linkage cabinet door 11 is opened and locked when earthing switch driving mechanism acts.
Earthing switch operation handle 13 is inserted into earthing switch handle hole 12 and ground connection driving mechanism for switches effect, ground connection can be opened
The separating brake and combined floodgate of earthing switch can be driven by closing the action of driving mechanism：Earthing switch operation handle 13 rotate clockwise 90 ° it is right
The combined floodgate of earthing switch is answered, is rotated by 90 ° the separating brake of corresponding earthing switch counterclockwise.Earthing switch operation handle 13 is to earthing switch
The spinning movement of handle hole 12 can be converted into the upper and lower of vertical output shaft 211 by the connecting shaft 210 of earthing switch driving mechanism
Movement, this belongs to the prior art, and details are not described herein.
The up and down motion of vertical output shaft 211 is converted by connecting lever 212 for the transverse movement of door bolt 213 again.Ground connection
When switching manipulation handle rotates clockwise 90 °, corresponding earthing switch closes a floodgate, and corresponding vertical output shaft is upward, corresponding door bolt 213
It moves right and leaves a door bolt hole 110, cabinet door 11 is opened；When earthing switch operation handle is rotated by 90 ° counterclockwise, correspondence connects
Ground switchs separating brake, and corresponding vertical output shaft is downward, and corresponding door bolt 213 is inserted into door bolt hole 110 to the left.I.e. earthing switch closes a floodgate
When cabinet door open, cabinet door locking during grounding switch tripping in this way, being grounded the interlocking of switch and cabinet door 11, ensure that operation
The safety of personnel.It is moved up for convenience of lifting cabinet door 11,11 outside of cabinet door is provided with spanner 114.
With continued reference to Fig. 3~Fig. 5, door includes a longitudinal pulling plate 221, one to shutter interlocking mechanism 22 and is connected to the drawing
The dynamic clamping head and quiet clamping head 222 and one of 221 upper end of plate is connected to the shutter 223 of 222 upper end of dynamic clamping head and quiet clamping head.Shutter 223
Before earthing switch handle hole 111, shutter 223 can be driven when pulling plate 221 moves in the vertical direction in vertical direction
Movement, and passing through dynamic clamping head and quiet clamping head 222 makes the pulling plate have upward restoring force；The lower end outwardly convex of pulling plate 221 is formed
One lower pulling plate bending plate 2211 is accordingly convexly equipped with a bending plate 110 on the inside of cabinet door 11.When cabinet door 11 is closed, door bending
Plate 110 presses to lower pulling plate bending plate 2211, moves downward pulling plate 221, and pulling plate 221 is blocked by the drive of dynamic clamping head and quiet clamping head 222
Plate 223 moves downward, and the up and down motion of shutter 223 can leave earthing switch handle hole 12, make earthing switch handle hole 12 exposed,
Dynamic clamping head and quiet clamping head 222 also has upward restoring force at this time.And then earthing switch operation handle 13 can be inserted into and connect by operating personnel
Ground switching manipulation hole 12 and to being grounded driving mechanism for switches rotation process, controls the combined floodgate and separating brake of earthing switch.
When cabinet door 11 in the open state, door bending plate 110 leaves lower pulling plate bending plate 2211, dynamic clamping head and quiet clamping head 222
It immediately falls back to original position, before shutter 223 returns to ground switching manipulation hole 12, block earthing switch handle hole with upward restoring force
12.Therefore in the open state, earthing switch operation handle 13 cannot be inserted into earthing switch handle hole 12 and dock cabinet door 11
Ground driving mechanism for switches rotation process makes grounding switch tripping or combined floodgate.
Again when cabinet door 11 is closed, earthing switch operation handle 13 is needed to revolve ground connection switching manipulation hole 12 counterclockwise
Turn 90 ° of operation, the separating brake of the corresponding earthing switch of this operation, and corresponding door bolt 213 is inserted into the right door bolt hole 111, makes cabinet
Door 11 is in and is locked and closed state.
In this way, a kind of ring main unit of embodiment of the utility model has the following technical effect that：Only to earthing switch
When handle hole 12 carries out earthing switch closing operation, door bolt 213 leaves door bolt hole 111, and cabinet door 11 can be just unlocked；
