Embodiment
The utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection range of the present utility model is made to more explicit defining.
Please refer to Fig. 1-Fig. 3 in embodiment of the present utility model, a kind of ring main unit of Novel interlocked structure, comprise cabinet, cabinet door, interlock and on-load switch, described on-load switch comprises: switch spindle 1, jack shaft 3 and disconnecting link 2, and it is inner to be arranged on described cabinet, described disconnecting link 2 is fixedly mounted on described jack shaft 3, and described jack shaft 3 is connected with the inner port of described switch spindle 1, and described interlock comprises: interlock plate 4, baffle plate 5 and pin block 6;
In the middle of described pin block 6, offer pin-and-hole, described pin block 6, between described cabinet door and described baffle plate 5, and is fixed on described cabinet behind the door;
Described interlock plate 4 is " Z " type, and its one end is fixedly installed in described switch spindle 1, and the other end can rotate to described pin block 6 places along with described switch spindle 1, and assigns in the pin-and-hole of described pin block 6;
Described baffle plate 5 is by the hinged top end that is installed on described cabinet inside, can do by described pendular movement centered by hinged, and when described cabinet door is opened, described baffle plate 5 is positioned at same lateral cross section with described interlocking 4;
The lateral length L of described interlock plate 4

Further illustrate, as shown in Figure 2, interlock schematic diagram while being in the lock state for ring main unit, when disconnecting link 2 is during in closing position, interlock plate 4 inserts in the pin-and-hole of pin block 6, locking cabinet door, then rotary switch main shaft 1, interlock plate 4 is rotation thereupon also, make the pin-and-hole of one end disengaging pin block 6 of interlock plate 4, now cabinet door is removed interlocking, open again cabinet door, the pin block 6 that is fixed on the cabinet door back side travels forward thereupon, now baffle plate 5 has departed from the extruding of pin block 6, according to self inertia, centered by hinged, travel forward, when baffle plate 5 is static just and interlock plate 4 in same lateral cross section, hindered the rotation of interlock plate 4, thereby switch spindle 1 cannot be rotated, thereby the disconnecting link in on-load switch 2 can not close a floodgate, having realized does not close the door does not allow the requirement of closing a floodgate,
As shown in Figure 3, for the interlock schematic diagram of ring main unit when the opening, when disconnecting link 2 is during in sub-gate position, interlock plate 4 is also in sub-gate position, now cabinet door is in released state, close again cabinet door, the pin block 6 that is fixed on the cabinet door back side is moved backward, head on baffle plate 5 swings backward simultaneously centered by hinged, directly cabinet door is closed completely, can remove the obstruction of interlock plate 4 rotations, switch spindle 1 can be rotated, thereby the disconnecting link in on-load switch 2 closes a floodgate smoothly, reach the object that could close a floodgate after the locking of must closing the door, until one end of interlock plate 4 rotation is inserted in the pin-and-hole of pin block 6, locking cabinet door, while reaching disconnecting link 2 combined floodgate, the object that cabinet door can not be opened.
In another preferred embodiment of the present utility model, in the middle of described cabinet 1, also offer cavity 7, the positive sealing steel plate 9 that adopts of described cavity 7 is shut, described cavity 7 internal weldings are connected to fluting steel plate 8, as shown in Figure 4, be the structural representation of described fluting steel plate 8, described fluting steel plate 8 is a rectangle steel plate, and be provided with three cutter grooves 81, described cutter groove 81 inside are the movement position of disconnecting link 5.
Be different from prior art, traditional ring main unit, when closing a floodgate, the epoxy plate that is put in cavity 7 inside need to be extracted out and is put on the ground, not only loaded down with trivial details but also occupy larger space, adopt now fluting steel plate 8 to be fixed in cavity 7 by the mode of welding, make disconnecting link just through the cutter groove on fluting steel plate 8, so both realize combined floodgate and the separating brake of disconnecting link, can also isolate a charged and interior personnel of cabinet, improve the safe class of ring main unit, and replace epoxy plate to reduce costs with fluting steel plate; By cavity 7 fronts are shut with sealing steel plate 9, can prevent that so extraneous metal object from entering space again, prevent and the disconnecting link generation electric shock phenomenon charged in closing position, the generation eliminating danger.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
