Detailed description of the invention
By particular specific embodiment explanation embodiments of the present invention, person skilled in the art scholar can be taken off by this description belowThe content of revealing is understood other advantages of the present invention and effect easily.
Refer to Fig. 1. Notice, appended graphic the illustrated structure of this description, ratio, size etc., all only say in order to coordinateThe content that bright book discloses, understands and reads for person skilled in the art scholar, not in order to limit the enforceable restriction of the present inventionCondition, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, at shadow notUnder effect that sound the present invention can produce and the object that can reach, all should still drop on disclosed technology contents and obtain and can containIn the scope of lid. Meanwhile, in this description, quote as " on ", D score, " left side ", " right side ", " centre " andThe term of " one " etc., also only for ease of the understanding of narration, but not in order to limit the enforceable scope of the present invention, its relativenessChange or adjustment, changing under technology contents, when being also considered as the enforceable category of the present invention without essence.
As shown in Figure 1, the invention provides a kind of metering cabinet with auto-lock function, this metering cabinet comprises a cabinet 1, cabinet 1Inside be provided with dividing plate, cabinet 1 is divided into cable vault 2 and handcart chamber 3 two parts, in cable vault 2, be provided with bus cable, wiring copperThe parts such as row, current transformer 8, kilowatt-hour meter. In handcart chamber 3, be provided with fuse handcart 4 and voltage transformer 9, fuse handCar 4 is provided with moving contact 5, is provided with the static contact 6 corresponding with moving contact 5 positions in cable vault 2, and fuse handcart 4 can beIn handcart chamber 3, move around, in the time that the inside propelling of fuse handcart 4 makes moving contact 5 with static contact 6 interlock, cable vault 2Circuit is in UNICOM's state; In the time that fuse handcart 4 is pulled outwardly the moving contact 5 of sening as an envoy to and departs from static contact 6, the line of cable vault 2Road is in off-state.
In handcart chamber 3, be also provided with primary importance inductive switch and a self-locking dolly 7, primary importance inductive switch is (not aobvious in figureShow) be positioned at a side of fuse handcart 4 sliding rails, primary importance inductive switch is for responding to the position of fuse handcart 4.Self-locking dolly 7 is connected with a driving mechanism, and primary importance induction installation is connected with this driving mechanism by a controller, and self-locking is littleCar 7 is positioned at the outside of fuse handcart 4; Driving mechanism can drive self-locking dolly 7 to carry out travelling backwards along fuse handcart 4 moving directionsMoving.
This metering cabinet in use, promotes fuse handcart 4 and moves inward, and makes fusing when fuse handcart 4 arrives assigned addressWhen moving contact 5 on device handcart 4 contacts with the static contact 6 in cable vault, primary importance inductive switch sends to feed back signal to and drivesActuation mechanism, makes driving mechanism drive self-locking dolly 7 to move fuse handcart dieback, so just can effectively avoid fuse handcartOn moving contact and static contact loosening. For convenient for unlocking, controller is also connected with a unlock switch, when needs fuse handcartWhen 4 moving contact 5 comes off with static contact 6, can directly press unlock switch, driving mechanism oppositely moves drive self-locking dolly 7Moving, so just can make fuse handcart 4 releases.
Because the moving contact 5 on fuse handcart 4 is located thereon end, in order to play good fixation, therefore self-locking is littleCar 7 should be corresponding with the upper end position of fuse handcart 4.
As a kind of preferred embodiment, driving mechanism comprises a motor, and motor is connected with a screw rod, and screw rod is provided with nut,Self-locking dolly is connected with nut, and motor is connected with controller, and motor rotarily drives screw rod rotation, and then drives the nut on screw rodMove around, and then self-locking dolly is moved around. Move around for the ease of self-locking dolly, self-locking dolly 5 can be arranged onOn one slide rail, and on slide rail, be provided with second place inductive switch, second place inductive switch is connected with a warning device, and secondLocation sensitive switch is for detection of the position of self-locking dolly 5. If in actual use, second place inductive switch is senseRequired self-locking dolly 5, illustrates that moving contact and static contact do not have interlock dead, is now reported to the police by warning device, to remind operatorMember overhauls equipment.
This metering cabinet, in the indoor position that primary importance inductive switch is set is used for responding to fuse handcart of handcart, is worked as fuse handcartWhen arrival assigned address makes the moving contact on fuse handcart contact with the static contact in cable vault, primary importance inductive switch sendsFeed back signal to driving mechanism, make driving mechanism drive self-locking dolly to move fuse handcart dieback, so just can effectively avoidMoving contact on fuse handcart and static contact are loosening, improve reliability and the security of metering cabinet work. So the present invention hasEffect has overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention. Anyly be familiar with this skillThe personage of art all can, under spirit of the present invention and category, modify or change above-described embodiment. Therefore, such asUnder have in technical field conventionally know the knowledgeable do not depart under disclosed spirit and technological thought, complete all etc.Effect is modified or is changed, and must be contained by claim of the present invention.
