Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the present invention are described further.
The specific embodiment 1 of switch cubicle many triggerings interlock of the present invention, as shown in Figure 1 to Figure 3.Wherein, 1 is stop catch plate, and 2 is action bars, and 3 is cable chamber door, 4 is revolving part, and 5 is replacement and fixation axle, and 6 is revolving part rotating shaft, and 7 is stop catch plate rotating shaft, 8 is casing, and 9,10 is trigger unit handle hole, stretches in casing for trigger unit action bars, and 11 is cable chamber door latch.In the present embodiment, the quantity of action bars is two, in real work, the quantity of action bars can increase according to the quantity of trigger unit and classification, the lifting of multiple trigger unit co-controlling action bars, can control same action bars with the trigger unit of identical category, trigger unit includes earthed switch, chopper, disconnecting switch etc..Stop catch plate 1 is provided with stop catch plate rotating shaft 7 away from one end (left end i.e. illustrated) of revolving part 4, and stop catch plate 1 can rotate around stop catch plate rotating shaft, installs torsion spring in stop catch plate rotating shaft 7, makes stop catch plate 1 be in position as shown in Figure 3 under not effect by external force.Stop catch plate 1, action bars 2 and torsion spring constitute Stop structure.Cable chamber door 3 is provided with cable chamber door latch 11, and cable chamber door latch 11 offers through hole, and through hole constitutes spacing hole.It is further fixed on gripper shoe in casing 8, microswitch is installed in gripper shoe, the hole in gripper shoe is inserted in one end of revolving part rotating shaft 6 and stop catch plate rotating shaft 7, stop catch plate 1 can drive microswitch, when stop catch plate 1 rotate revolving part 4 is carried out block time, microswitch sends signal, and when stop catch plate 1 reset stops that revolving part is carried out block, microswitch stops sending signal.
The lower end of the revolving part 4 shown in Fig. 2 is the lock part of revolving part, the lock part side zero defect of revolving part, and opposite side is inclined-plane.The diagram opening direction that direction is cable chamber door 3 to the right, is the direction of cable chamber door 3 closedown to the left.Revolving part lock part is designed as shape as shown in Figure 2, is in order to when cable chamber door is opened to the right, revolving part lock part is by the interference of hole, unrestricted position hole wall when screwing out in cable chamber door spacing hole.Revolving part 4 can 6 rotate around the shaft, installs fixing axle 5 on revolving part 4, and fixing axle 5 is positioned on revolving part, and the axis of fixing axle 5 is parallel with the axis of rotating shaft 6.Fixing axle 5 is fixed the structures such as elastic component such as spring, the other end of elastic component is fixed in gripper shoe or casing.Revolving part shown in Fig. 2 is in locking position, and the revolving part shown in Fig. 3 is in solution lock-bit.
When trigger unit triggers its corresponding action bars, action bars 2 moves up, now the combined floodgate of the earthed switch in high-tension switch cabinet, breaker open operation, disconnecting switch separating brake occur simultaneously, stop catch plate 1 is not acted on by the pressing of action bars 2, in stop catch plate rotating shaft 7 under the effect of torsion spring, stop catch plate 1 rotates counterclockwise, and the right-hand member of stop catch plate 1 no longer contacts with the left side of revolving part 4, and the rotation of revolving part 4 is unrestricted.Now, when cable chamber door is opened to the right, being rotated counterclockwise by the thrust of cable chamber door latch 11 upper limit hole left side wall on the left of revolving part lock part, revolving part lock part rotates cable chamber door spacing hole, makes cable chamber door open smoothly.Fig. 3 shows that middle revolving part location is solution lock-bit, and revolving part is in extreme displacement, and one end of revolving part keeps contacting with the surface of latch.
When maintainer overhaul complete need close cable chamber door time, cable chamber door is promoted to left direction as shown in Figure 3, revolving part 4 rotates under the restoring force effect of elastic reset part on replacement and fixation axle 5 clockwise, making revolving part lock part reinsert in the spacing hole of cable chamber door latch, revolving part 4 comes back to locking position.Trigger unit triggers its corresponding action bars again, i.e. grounding switch tripping and/or chopper, disconnecting switch combined floodgate in high-tension switch cabinet, stop catch plate 1 can rotate clockwise under the pressing effect of action bars 2, comes back to the position shown in Fig. 2, limits revolving part 4 and rotates counterclockwise.
Switch cubicle many triggerings interlock of the present invention, when the non-trigger action bar of the trigger unit in high-tension switch cabinet, i.e. when grounding switch tripping and/or chopper, disconnecting switch combined floodgate, cable chamber door cannot be opened；When the trigger unit trigger action bar in high-tension switch cabinet, when i.e. grounding switch tripping, breaker closing, disconnecting switch combined floodgate etc. occur simultaneously, cable chamber door can be opened.Using purely mechanic structure, simple in construction, advantage of lower cost, reliability is high, and protective is good.
The embodiment 2 of switch cubicle many triggerings interlock of the present invention is as shown in Figure 4, it is with the difference of embodiment 1, revolving part stop part in embodiment 2 only has action bars 12, and the structure of action bars is consistent with embodiment 1, and the direct rotation to revolving part of action bars 12 is controlled.
The embodiment 3 of switch cubicle many triggerings interlock of the present invention is as it is shown in figure 5, be with the difference of embodiment 1, and in the present embodiment, stop part includes action bars 15 and stop catch plate 13, on the spring structure 14 that stop catch plate 13 is fixed on casing.Action bars 14 moves down, and promotes stop catch plate 13 compression spring 14, makes stop catch plate 13 be in position as shown in Figure 5, stops revolving part 4 to rotate；Action bars 15 moves up, and stop catch plate 13 is moved up by the restoring force of spring 14, makes the right-hand member of stop catch plate 13 no longer contact with the left end of revolving part, and now revolving part rotates counterclockwise when cable chamber door is opened to the right.
In other embodiments of switch cubicle many triggerings interlock of the present invention, revolving part elastic reset part can be other structure, resets revolving part as installed torsion spring in revolving part rotating shaft 6.Elastic component on replacement and fixation axle 5 can be other elastic constructions such as rubber strip.
In other embodiments of switch cubicle many triggerings interlock of the present invention, other resetting structure can be provided with on stop catch plate, as arranged fixing axle on stop catch plate, elastic component is set between fixing axle and casing, enables stop catch plate to be rotated counterclockwise when not acting on by external force.
In other embodiments of switch cubicle many triggerings interlock of the present invention, Stop structure can be arranged on the right side of revolving part, but when being arranged on right side, the contact point of Stop structure and revolving part must be positioned at the lower section of revolving part rotating shaft 6 place horizontal plane.
