Abstract
The utility model relates to a directional blasting cutting type rapid isolator, comprising a cylinder body and a conductor arranged in the cylinder body. One side of the conductor is equipped with a blasting groove in which an explosive detonated by a detonating cord is filled, and the detonating cord is connected with an electric detonator; the electric detonator is connected with the signal output end of an electronic controller, the inner side of the cylinder body end face is equipped with an insulating plate, a rogowski coil sleeved on the outside of the conductor is internally arranged between the insulating plate and the cylinder body end face and is connected with the signal input end of the electronic controller. The rogowski coil is arranged in the insulating cylinder body, so that the insulation problem of the rogowski coil and the ground does not need to be considered, the structure is simplified substantially, the design and manufacture difficulties are reduced, and the cost is reduced.
Description
Technical field
The utility model relates to the quick isolator of a kind of directional blasting cutting type, is mainly used in the path of fast shut-off short circuit current in the current supply circuit.
Background technology
In electric power systems such as generating, power transformation and power supply, break down when short circuit current occurring, be the stability of protection equipment, circuit, avoid receiving short circuit current and damage, need use circuit breaker and carry out fast shut-off.The present all kinds of circuit breaker standard-sized sheet break times maintain 100-200ms basically; So at this moment; Each equipment must tolerate temperature rise and the surge that is caused by short circuit current, and its manufacturing to equipment has proposed very high requirement, particularly along with the continuous increase of each place capacity in the electric power system; This problem has become the biggest problem of device fabrication, and it is extremely urgent further to develop the device that shortens the breaker open operation time or develop a kind of more fast shut-off short circuit current.
The device of existing corresponding function occurs on the market at present, and it comprises insulating cylinder body, is located at the electric conductor in the cylindrical shell, and electric conductor one side is provided with the explosion groove, in the explosion groove, is filled with the explosive of being ignited by explosive rope, and explosive rope is connected with electric cap.Detect the big current signal that passes through on the electric conductor through Luo-coil, drive explosive rope ignition charge, fast shut-off electric conductor by electronic controller control electric cap.The shortcoming of this kind structure is: the Luo-coil that detects the electric conductor electric current is arranged on the rectangle line bank that is connected with electric conductor, is positioned at the cylindrical shell outside, needs the Insulation Problems on high pressure with the ground of solution Luo-coil, has improved manufacture difficulty and cost.
Summary of the invention
The technical problem that the utility model will solve provides a kind of simple in structure, easily manufactured quick isolator of directional blasting cutting type.
For solving the problems of the technologies described above, the technical scheme of the utility model is: the quick isolator of a kind of directional blasting cutting type comprises cylindrical shell; Be located at the electric conductor in the cylindrical shell; Said electric conductor one side is provided with the explosion groove, is filled with the explosive of being ignited by explosive rope in the said explosion groove, and explosive rope is connected with electric cap; Electric cap is connected with the signal output part of electronic controller; Its innovative point is: said body end surface inboard is provided with insulation board, is built-in with between said insulation board and the body end surface to be sleeved on the outer Luo-coil of electric conductor, and said Luo-coil is connected with the signal input part of electronic controller.
The advantage of the utility model is: Luo-coil is arranged in the insulating cylinder body, need not to consider the Insulation Problems on Luo-coil and ground, simplifies the structure greatly, has reduced design and manufacture difficulty, has reduced cost.
Description of drawings
Accompanying drawing is the quick spacer structures sketch map of the utility model directional blasting cutting type.
Embodiment
Shown in accompanying drawing, comprise isolator cylindrical shell 1, electric conductor 2, insulated bearing plate 3, explosion groove, explosive 5, breach 6, Luo-coil 7.
Be provided with pair of conductive body 2 in the above-mentioned cylindrical shell 1; Electric conductor 2 is a rectangular configuration; The end face of cylindrical shell 1 is all stretched out at its two ends, through bolt clip insulated bearing plate 3 is housed between the part of two electric conductors 2 in cylindrical shell 1, has the explosion groove at electric conductor 2 near a side surface of insulated bearing plate 3; Be filled with explosive 5 in the explosion groove, explosive 5 is connected with electric cap through explosive rope.
The opposite side surface that electric conductor 2 is not established the explosion groove has the breach 6 that electric conductor 2 is formed weakness.
Cylindrical shell 1 end face inboard is provided with insulation board 8; Be built-in with the Luo-coil 7 that is sleeved on outside the electric conductor 2 between this insulation board 8 and cylindrical shell 1 end face; The output signal of this Luo-coil 7 inserts electronic controller through cable, and the ignition signal of electronic controller inserts electric cap.
During work; By the electric current on the Luo-coil 7 detection electric conductors 2; Current signal is flowed to electronic controller, and when this current signal value surpassed the cut-out threshold values of setting, electronic controller sent ignition signal and gives the electric cap that is built in the isolator; Electric cap drives explosive rope and explosive charge, and the impulsive force of blast is at extremely short time internal cutting off electric conductor 2.Luo-coil 7 is arranged in the insulating cylinder body 1, need not to consider the Insulation Problems on Luo-coil 7 and ground, simplifies the structure greatly, has reduced design and manufacture difficulty, has reduced cost.
