Abstract
The utility model relates to a medium-voltage distributing board bus-bar earthing knife interlocking protective structure for boat, which is used for the medium-voltage distributing board, and is characterized in that the protective structure includes a break room locking device, a bus-bar earthing knife locking device and an interlocking key; each incoming cabinet in the system is internally provided with a set of locking device for the breaker room, and each set of breaker room locking device is provided with an interlocking key; moreover, the bus-bar earthing knife interlocking protective structure is arranged in a feeder panel; wherein, a program lock 1 is positioned at the upper left angle, and a breaker 2 is arranged on the handcart 3 of the breaker; the program lock 1 and the breaker handcart 3 are at the working station 4, and the breaker handcart 3 is at the test station 5, and 6 is a side plate. The structure is arranged in the medium-voltage distributing system for boat, which prevents insecurity problem to people and device while opening and closing the brake, thereby satisfying the requirements of ship running.
Description
Technical field
The utility model relates to a kind of medium-voltage distribution plate busbar ground connection cutter interlock, relates to a kind of medium-voltage distribution plate busbar ground connection cutter interlock peculiar to vessel or rather, belongs to electrical technology field.
Background technology
In intermediate distribution system peculiar to vessel, for reducing the installing space of whole distribution system, so the ground connection cutter of bus is installed in the wherein a certain switchboard.
But prior art is installed in the ground connection cutter of bus in the switchboard, to the poor stability of people and equipment, does not meet the ships service requirement when divide-shut brake.
Summary of the invention
The purpose of this utility model is to provide a kind of medium-voltage distribution plate busbar ground connection cutter interlock protection structure peculiar to vessel, and this structure all can lock during in dead electricity, in "on" position, plays a protective role.
For achieving the above object, the technical solution of the utility model is: the interlock protection structure of busbar grounding cutter comprises breaker chamber locking device, busbar grounding cutter locking device and interlocking key.The locking device of one cover breaker chamber is installed in every incoming line cabinet in the system, and every cover breaker chamber locking device has an interlocking key, and busbar grounding cutter interlock protection structure is installed in the switchboard.
The beneficial effects of the utility model: in the utility model, be installed in the intermediate distribution system peculiar to vessel with this structure, can not go out the condition prior art problems, the fail safe to people and equipment when divide-shut brake is good, meets the ships service requirement.
Below in conjunction with drawings and Examples to the utility model detailed explanation of making comparisons.
Description of drawings
Fig. 1 is a medium-voltage distribution plate busbar ground connection cutter interlocking general structure schematic diagram of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a medium-voltage distribution plate busbar ground connection cutter interlock program locking lock view of the present utility model;
Fig. 4 is a medium-voltage distribution plate busbar ground connection cutter interlock program lock released state schematic diagram of the present utility model.
Embodiment
With reference to Fig. 1, this is a medium-voltage distribution plate busbar ground connection cutter interlocking general structure schematic diagram of the present utility model.
As shown in the figure, procedure lock 1 is positioned at the upper left corner, and circuit breaker 2 is on circuit breaker cart 3.
With reference to Fig. 2, this is the vertical view of Fig. 1.
As shown in the figure, procedure lock 1, circuit breaker cart 3 is in service position 4, and it is side plate that circuit breaker cart 3 is in test position 5,6.
Fig. 3, Fig. 4 are medium-voltage distribution plate busbar ground connection cutter interlock program locking lock state of the present utility model and release view.
When program was in locking lock state, 7 was that lockhole, 8 is that locking bar, 9 is construction bolt; When procedure lock was in released state, locking bar 8 was moved to the left, its position.Lockhole 7, construction bolt 9 remain unchanged.
In the intermediate distribution system of a plurality of power supply parallel operations, respectively preceding two two ends, the left and right sides that are installed on the incoming line cabinet circuit breaker of one group three procedure lock.After test position, procedure lock can move and pin handcart and extract key circuit breaker by the service position, and circuit breaker can't enter the service position because of procedure lock under blocking.
After all incoming line cabinets are all pressed as above operation, guarantee that bus is at power failure state.Can be with the key release busbar grounding cutter interlocking device that pulls out on all incoming line cabinet circuit breakers, three procedure lock must be in order from top to bottom release ground connection cutter can close a floodgate.After the ground connection cutter closed a floodgate, the procedure lock key on the busbar grounding cutter interlock can't be pulled out, and guarantees that handcart when the busbar grounding cutter closes a floodgate, can't advance as the service position and send.
Though the utility model is described with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is used for illustrating the utility model; should understand and wherein can make variations and modifications and do not break away from the utility model in a broad sense; so be not that conduct is to qualification of the present utility model; as long as in connotation scope of the present utility model, to the variation of above-described embodiment, the protection range that distortion all will fall into the utility model claim.
