Abstract
The utility model relates to a directional blasting cutting type quick isolator which comprises a cylinder body and a conductive body, wherein the conductive body is arranged in the cylinder body, a bursting groove is arranged at one side of the conductive body, explosive detonated by a detonating cord is filled in the bursting groove, and the detonating cord is connected with an electric detonator. The directional blasting cutting type quick isolator is characterized in that the conductive body is of a rectangular structure, and the two ends of the conductive body extend out of the end surface of the cylinder body. The conductive body is of the rectangular structure, a rectangular wiring terminal is fixed at the two ends of the conductive body through bolts without welding connection after the two ends of the conductive body extend out of the end surface of the cylinder body, the manufacturing is convenient, requirements on temperature rise can be met, and the improvement of voltage level is facilitated.
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 IS flow restricter of existing corresponding function occurs on the market at present, and it comprises cylindrical shell, is located at the cylindrical conductive body 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 outside rectangle binding post welding of the two ends of cylindrical conductive body and cylindrical shell is fixed, and this kind structure has satisfied not the temperature rise requirement, and its specification receives certain restriction, is unfavorable for improving electric pressure.
Summary of the invention
The technical problem that the utility model will solve provides a kind of quick isolator of directional blasting cutting type that helps improving electric pressure.
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, comprise cylindrical shell, and be located at the electric conductor in the cylindrical shell; Said electric conductor one side is provided with the explosion groove; Be filled with the explosive of being ignited by explosive rope in the said explosion groove, explosive rope is connected with electric cap, and its innovative point is: said electric conductor is the rectangular configuration that body end surface is stretched out at two ends.
The advantage of the utility model is: electric conductor is a rectangular configuration, and its two ends are fixed through bolt and rectangle binding post after stretching out body end surface, need not to be welded to connect, and are easy to make, can satisfy the temperature rise requirement, help the raising of electric pressure.
Description of drawings
Fig. 1 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.
Also be built-in with the Luo-coil 7 that detects electric current on the electric conductor 2 in the cylindrical shell 1, 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.Electric conductor 2 is a rectangular configuration, when its two ends are connected with the rectangle binding post, can pass through bolt, nut and connect fixingly, need not to be welded to connect, and is easy to make, can satisfy the temperature rise requirement, helps the raising of electric pressure.
