Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The isolation handcart of the present embodiment as shown in Figure 1, comprising: vehicle frame 1, be arranged on the rotating mechanism 2 in described vehicle frame 1 and the handle 3 outside vehicle frame 1, and described handle 3 drives rotating mechanism 2 to rotate.Rotating mechanism 2 is a set of rotating mechanisms based on worm screw, is usually arranged on the chassis of the vehicle frame 1 of isolation handcart.Also comprise: be arranged on the baffle plate 4 on described vehicle frame 1 and latching electromagnet 5, baffle plate 4 is arranged on described vehicle frame 1 movably, and between described rotating mechanism 2 and latching electromagnet 5.Described rotating mechanism 2 is withstood in one end of described baffle plate 4, and the other end coordinates to pin or unclamp described rotating mechanism 2 with described latching electromagnet 5.
The isolation handcart of the present embodiment has installed latching electromagnet 5, is pinned or unclamp rotating mechanism 2 by latching electromagnet 5, thus avoids and under bus "on" position, to isolate handcart push by mistake or release the safety problem that lifting cabinet causes.
Described latching electromagnet 5 comprises iron core 51 and dead bolt 52, and iron core 51 electric connecting busbar circuit breaker, dead bolt 52 magnetic connects described iron core 51.The other end of baffle plate 4 coordinates with dead bolt 52 to pin or unclamp described rotating mechanism 2.
As shown in Figure 2, latching electromagnet 5 is in the state of locking, latching electromagnet 5 dead electricity now, iron core 51 can not adhesive dead bolt 52, and dead bolt 52 stretches out, and props up baffle plate 4, baffle plate 4 other end blocks rotating mechanism 2, and rotating mechanism can not be rotated, thus pins pushing or releasing of isolation handcart.As shown in Figure 3, latching electromagnet 5 is in the state of unblock, latching electromagnet 5 now obtains electric, iron core 51 adhesive dead bolt 52 is retracted, because baffle plate 4 is movably arranged on vehicle frame 1, baffle plate 1 can move left and right, and is backed down by baffle plate 4 when rotating mechanism 2 rotates, freely rotate, runner wagon is pushed or releases.
The utility model additionally provides a kind of middle metal enclosed switchgear, comprising: mother cabinet and lifting cabinet, also comprise: above-mentioned isolation handcart.As shown in Figure 4, DC control supply ± KM, the two poles of the earth DC circuit breaker ZK is comprised in described lifting cabinet.The auxiliary contact QF of the bus in the positive pole+KM of DC control supply, the positive pole of DC circuit breaker ZK, mother cabinet, the isolation latching electromagnet 5 of handcart, the negative pole of DC circuit breaker ZK and DC control supply negative pole-KM, be connected into electric blocking loop successively.
Because the auxiliary contact QF of bus is arranged in mother cabinet, in the present embodiment, the auxiliary contact QF of the bus in mother cabinet is introduced in described lifting cabinet, to facilitate connection by connecting wire.
The interlocking logic of mother cabinet and lifting cabinet is as shown in table 1 below:
The interlocking logical table of table 1 mother cabinet and lifting cabinet
| Mother cabinet breaker deciliter state | Lifting cabinet isolation handcart position state |
| Breaker open operation | Allow the turnover of isolation handcart |
| Breaker closing | Forbid the turnover of isolation handcart |
Namely when bus is in gate-dividing state, bus auxiliary contact QF closes, and the latching electromagnet on isolation handcart obtains electrolysis lock (in Fig. 3, iron core drinks up dead bolt), swinging handle, rotating mechanism backs down baffle plate when rotating, and isolation handcart is pushed or released.Otherwise, when bus is in "on" position, bus auxiliary contact QF opens, latching electromagnet dead electricity on isolation handcart, iron core can not adhesive (in Fig. 2 iron core can not adhesive dead bolt), dead bolt blocks the rotating mechanism on isolation handcart chassis by baffle plate, and now the rotating mechanism of isolating in handcart can not rotate, and isolation handcart can not be pushed or release.
Lifting cabinet isolation handcart installs the design of latching electromagnet additional, reciprocal interlocked by isolation handcart and bus to reach the object of safe operation, even if high-tension switch cabinet in use, runs into the situation causing " informal operation " due to the carelessness of operator or abnormal operation power.In this case, interlocking can accomplish that " the informal operation " that may occur operator has prevention or prevention ability fully highly reliably.The correctness of operation sequence itself can be ensured, and the safe operation of power network, guarantee equipment and personal safety, prevent on-load misoperation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
