Description
Technical field
The utility model relates to a kind of secondary of high voltage switchgear and plugs in interlock.
Background technology
At existing console mode handcart high-voltage switch equipment, between handcart and the high-tension switch cabinet except one time high-pressure section is connected, also need the secondary control section to connect, the connection of secondary control section connects by secondary plug, during maintenance, secondary plug need be pulled out, handcart is shifted out, if secondary plug is not extracted, and withdraw from handcart by force, secondary plug will damage.Do not have mandatory requirement between secondary overlap joint and the removable handcart of high pressure, to set up this interlock in the prior art standard, thereby the operator occurs forgetting earlier with the secondary overlap joint separately easily in operating process, just withdraw from handcart by force, cause the secondary plug damage.
Summary of the invention
The utility model purpose is to provide the secondary of high voltage switchgear a kind of simple in structure, with low cost to plug in interlock.
It is such that technology of the present utility model constitutes: it comprises connecting lever, brake cable, baffle plate, back-moving spring; The end of described connecting lever is connecting an end of brake cable, and the other end of brake cable is connecting baffle plate, and the other end of baffle plate also is provided with back-moving spring.
The utlity model has following advantage: 1, simple structure, reduce the link and take up room, need not the purpose that the complicated mechanical conversion just can reach locking.2, make interlock easy to operate stable and reliable.
Description of drawings
Fig. 1 is a concrete structure schematic diagram of the present utility model.
Label declaration: 1 connecting lever, 2 brake cable, 3 baffle plates, 3-1 slotted hole, 3-2 bolt, 4 back-moving springs, 5 handcarts, 6, interlocking handle, 6-1 locking device, 7 secondary plugs, 8 Secondary sockets, 9 connecting lever fixed mounts, 10 bent plates.
Embodiment
Below in conjunction with description of drawings the utility model is described:
As shown in Figure 1, the utility model comprises connecting lever 1, brake cable 2, baffle plate 3, back-moving spring 4; The end of described connecting lever 1 is connecting an end of brake cable 2, and the other end of brake cable is connecting baffle plate 3, and the other end of baffle plate also is provided with back-moving spring 4.By the motion pulling brake cable of connecting lever, and then drive moving of baffle plate.
Connecting lever, brake cable, baffle plate, back-moving spring are fixed in the handcart 5.The Secondary socket 8 that also is provided with in the handcart, connecting lever fixed mount 9, bent plate 10 and interlocking handle 6, Secondary socket 8 is fixed on the handcart upper surface, connecting lever fixed mount 9 is arranged on by the Secondary socket, connecting lever is connected on the connecting lever fixed mount, the end that connecting lever does not have brake cable extends to the Secondary socket top, is provided with bent plate 10 in the junction of brake cable and baffle plate and the junction of brake cable and connecting lever fixed mount, and bent plate is provided with circular hole, brake cable is passed the circular hole on the bent plate, and brake cable is fixed on the handcart by bent plate.
Baffle plate is positioned at the top of interlocking handle.Baffle plate is a step structure, and baffle plate is provided with slotted hole 3-1, and bolt 3-2 is fixed on baffle plate on the handcart by slotted hole.Minimum point when the bottom of wider portion is with interlocking grip closure state in the baffle plate step structure is equal, and the minimum point the when bottom of narrower part is with interlocking grip opening in the baffle plate step structure is equal.By the variation of controllable register ladder-shaper structure width, can decision open at the interlocking handle of lock-out state.
The end that connecting lever is provided with brake cable extends to bent plate and contacts with bent plate, and bent plate is positioned at the junction of brake cable and connecting lever fixed mount.When secondary plug did not insert Secondary socket, connecting lever was replied under action of reset spring, when connecting lever with after bent plate contacts, the connecting lever spring pulling that just can not be reset.
Below operation principle when being applied to the removable handcart of high pressure for the utility model
During use, earlier shift handcart onto high-tension switch cabinet required position of laying, lay appropriate after, locking device on the interlocking handle will make handcart be in the lock state, under the situation of not pull-up interlocking handle, handcart will be fixed on the required position of laying, the part that then connecting lever is extended to the Secondary socket top is drawn back, secondary plug is inserted on the Secondary socket, in the pulling connecting lever, baffle plate also can be driven, and makes baffle plate make the bottom of wider portion in the baffle plate step structure be stuck in the top of interlocking handle, interlock handle this moment can't pull-up, and handcart continues to be in the lock state; After secondary plug unpluged, connecting lever was returned to the origin-location, thereby the bottom of narrower part is returned to the top of interlocking handle in the baffle plate step structure, pull-up interlocking handle, and handcart is in released state, and just can pull out handcart this moment.
By above-mentioned design, to have avoided in the operation in the past, operating personnel's inadvertent not pulling up earlier under the situation of secondary plug, is pulled out dolly, causes the damage of secondary plug.By adopting the mode that is flexible coupling of brake cable, can reduce transmission link simultaneously, save the handcart inner space, save cost.
