Abstract
The utility model relates to an outdoor directional blasting cutting type quick isolator, which comprises an insulation cylinder, end covers arranged at two ends of the cylinder and a conductive body installed in the cylinder. A blowout groove is arranged on one side of the conductive body and filled with explosive detonated by a detonating fuse connected with an electric detonator which is connected with the signal output end of an electric controller. The outdoor directional blasting cutting type quick isolator is characterized in that the outer surface of the cylinder is in a wave-shaped structure. When outdoor directional blasting cutting type quick isolator works, a Rogowski coil is utilized to detect short-circuit current. The electric controller controls the electric detonator to drive the detonating fuse to detonate the explosive, and the conductive body is quickly cut off to protect the device. Because the outer surface cylinder is in a wave-shaped structure, creep distance is increased, and safety is improved.
Description
Technical field
The utility model relates to the quick isolator of a kind of outdoor 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 outer surface of insulating cylinder body is smooth cylinder barrel shaped; Its creepage distance is the distance between the cylindrical shell both ends of the surface; Creepage distance is less; When using out of doors, thereby may occur between device or strike sparks between device and the ground threatening personal safety, fail safe receives certain influence.
Summary of the invention
The technical problem that the utility model will solve provides a kind of safe quick isolator of outdoor 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 outdoor directional blasting cutting type comprises insulating cylinder body; Be located at the end cap at cylindrical shell two ends, and be installed in the electric conductor in the cylindrical shell, said electric conductor one side is provided with the explosion groove; Be filled with the explosive of igniting by explosive rope in the said explosion groove; Explosive rope is connected with electric cap, and electric cap is connected with the signal output part of electronic controller, and its innovative point is: said barrel outer surface is a wavy shaped configuration.
Further, said cylindrical shell scribbles one deck insulation enamelled coating outward.
Further, said insulation enamelled coating scribbles antiultraviolet fluorocarbon layer and anti-pollution flashover layer outward.
The advantage of the utility model is: utilize Luo-coil to detect short circuit current during work, electronic controller control electric cap drives the explosive rope ignition charge, and the fast shut-off electric conductor comes protection equipment.Barrel outer surface is a wavy shaped configuration, has increased creepage distance, has improved fail safe.
Description of drawings
Accompanying drawing 1 is the quick spacer structures sketch map of the utility model outdoor 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.
Above-mentioned insulating cylinder body 1 outer surface is a waveform, and its two ends are provided with end cap 9, are provided with pair of conductive body 2 in the cylindrical shell 1; Electric conductor 2 is a rectangular configuration; Its two ends are all stretched out between the part of end face end cap 9, two electric conductors 2 in cylindrical shell 1 of cylindrical shell 1 and through bolt clip insulated bearing plate 3 are housed, and have 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.Scribble one deck insulation enamelled coating outside the cylindrical shell 1, and outside the insulation enamelled coating, scribble antiultraviolet fluorocarbon layer and anti-pollution flashover layer.
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 end cap 9 inboards are 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 the end cap 9; The output signal of this Luo-coil 7 inserts electronic controller 10 through cable 11, and the ignition signal of electronic controller 10 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.
Claims (3)
