Technical field
The present invention relates to block sytem field, especially a kind of ring main unit mechanical closure system.
Background technology
In the prior art, the machinery between the mechanical chain between ring main unit earthed switch and Xiamen, main switch and Xiamen
It is chain that higher is required to Xiamen manufacturing process, it is also higher to the cooperation between Xiamen and door shelves；Manufacturing cost is high, whole chain
Realization coordinated by sliding block and Xiamen to realize, it is necessary to process the sliding block of two special materials.
The content of the invention
The technical problems to be solved by the invention are, there is provided a kind of ring main unit mechanical closure system rational in infrastructure, into
This is cheap, reliable and stable.
In order to solve the above technical problems, a kind of ring main unit mechanical closure system of present invention offer, including the chain axle 1 in Xiamen,
It is grounded chain axle 2, the chain stage clip 3 in Xiamen, the chain stage clip 4 of ground connection, chain bracing wire 5, chain fixed installation plate 6 and axle elasticity gear
Circle 7；It is grounded chain axle 2 and is fixed on by being grounded chain stage clip 4 and circlip for shaft 7 on chain fixed installation plate 6, Xiamen connects
Lock shaft 1 is fixed on chain fixed installation plate 6 by the chain stage clip 3 in Xiamen and circlip for shaft 7, and chain bracing wire 5, which passes through, to be connected
The chain bayonet socket that plate is fixedly mounted is by the chain stuck fixation of bracing wire external diameter, the lower end of the chain core of bracing wire 5 during Dingan County's loading board 6 that locks
Coordinated by screw thread and be fixed on the chain axle 1 in Xiamen and the chain axle 2 of ground connection.
Preferably, ring main unit mechanical closure system has 2 kinds of working conditions：Main switch separating brake closes earthed switch and opens Xiamen：
Main switch is under gate-dividing state, and earthed switch mechanism drives the chain axle 2 of ground connection to the right by chain bracing wire 5 when earthed switch closes a floodgate
Motion, is grounded chain stage clip 4 and compresses, and is grounded contact of earth when chain stage clip 4 is compressed to minimal compression amount and completes, while the company of ground connection
The notch of lock shaft 2 from the chain axle 1 in Xiamen withdraws to surface lifting Xiamen and lays down Xiamen, the Xiamen in the presence of the gravity of Xiamen
Chain stage clip 3 is had been under compressive state, and when laying down Xiamen, the chain up resilience of stage clip 3 in Xiamen, is driven by chain bracing wire 5
The chain hole locking main switch of main switch is not operated, realize what main switch handle hole in the case that Xiamen is opened can not operate
It is chain.
Closing Xiamen divides earthed switch to close main switch：Xiamen is installed because Action of Gravity Field compresses the chain stage clip 3 in Xiamen, simultaneously
Chain bracing wire 5 stretches downwards the chain hole of main switch and opened, and main switch hole can operate, and Xiamen installation divides earthed switch,
It is grounded the external force of operating mechanism and is grounded chain bracing wire 5 under the double action of chain stage clip 4 and, to left movement, drives the chain axle of ground connection
2, to left movement, are grounded the chain bayonet socket of axle 2 and are stuck in the notch of the chain axle 1 in Xiamen, Xiamen locking can not open, and realize ground connection
Xiamen can not open during separating brake, and earthed switch combined floodgate completes main switch and carries out operation division.
Preferably, earthed switch mechanism is domestic imitative ABB SafeRing gas-filling cabinet earthing switch operating mechanisms.
Beneficial effects of the present invention are：Chain fixed installation plate is made with sheet metal component bending, and cost is low to be easily installed
And dismounting；The whole chain only chain axle in Xiamen is connected with Xiamen, realize main switch with Xiamen chain, earthed switch and under
Door is chain, chain more reliable and more stable by an axle and Xiamen；It is grounded chain axle and directly locks the chain axle in Xiamen, not only realizes
The function of lock Xiamen also achieves the function of lock primary operating hole, more securely and reliably；Supporting pull-type card links up with door, reliability
It is high.

Embodiment
As illustrated in fig. 1 and 2, a kind of ring main unit mechanical closure system, including the chain axle 1 in Xiamen, the chain axle 2 of ground connection, Xiamen
Chain stage clip 3, the chain stage clip 4 of ground connection, chain bracing wire 5, chain fixed installation plate 6 and circlip for shaft 7；It is grounded chain axle 2
It is fixed on by being grounded chain stage clip 4 and circlip for shaft 7 on chain fixed installation plate 6, the chain axle 1 in Xiamen is connected by Xiamen
Lock stage clip 3 and circlip for shaft 7 are fixed on chain fixed installation plate 6, when chain bracing wire 5 is through chain fixed installation plate 6
The chain bayonet socket that plate is fixedly mounted coordinates the chain stuck fixation of bracing wire external diameter, the lower end of the chain core of bracing wire 5 admittedly by screw thread
It is scheduled on the chain axle 1 in Xiamen and is grounded chain axle 2.
As shown in figure 3, ring main unit mechanical closure system has 2 kinds of working conditions：Main switch separating brake is closed under earthed switch opening
Door：Main switch is under gate-dividing state, and earthed switch mechanism drives the chain axle 2 of ground connection by chain bracing wire 5 when earthed switch closes a floodgate
Move right, be grounded chain stage clip 4 and compress, be grounded contact of earth when chain stage clip 4 is compressed to minimal compression amount and complete, connect simultaneously
The notch of the chain axle 2 in ground from the chain axle 1 in Xiamen withdraws to surface lifting Xiamen and lays down Xiamen, in the presence of the gravity of Xiamen
The chain stage clip 3 in Xiamen is had been under compressive state, and when laying down Xiamen, the chain up resilience of stage clip 3 in Xiamen, passes through chain drawing
Line 5 drives the chain hole locking main switch of main switch not operate, and main switch handle hole can not in the case of realizing Xiamen opening
What is operated is chain.
Closing Xiamen divides earthed switch to close main switch：Xiamen is installed because Action of Gravity Field compresses the chain stage clip 3 in Xiamen, simultaneously
Chain bracing wire 5 stretches downwards the chain hole of main switch and opened, and main switch hole can operate, and Xiamen installation divides earthed switch,
It is grounded the external force of operating mechanism and is grounded chain bracing wire 5 under the double action of chain stage clip 4 and, to left movement, drives the chain axle of ground connection
2, to left movement, are grounded the chain bayonet socket of axle 2 and are stuck in the notch of the chain axle 1 in Xiamen, Xiamen locking can not open, and realize ground connection
Xiamen can not open during separating brake, and earthed switch combined floodgate completes main switch and carries out operation division.
Earthed switch mechanism is domestic imitative ABB SafeRing gas-filling cabinet earthing switch operating mechanisms.
Whole system fits through the outer of the gravity of Xiamen and the pressure of spring and operating mechanism by two chain axles
Power is anti-chain so as to reach five to realize the interlocking between main switch earthed switch and Xiamen.
Although the present invention is illustrated and described with regard to preferred embodiment, it is understood by those skilled in the art that
Without departing from scope defined by the claims of the present invention, variations and modifications can be carried out to the present invention.
