Embodiment Construction

[0018] Referring to Figures 1 and 2, the present invention consists of an explosion control system and an explosion breaking device, which are connected in parallel to the M of the main line 1 , M 2 On two connecting ends (in use); the explosion control system is composed of a controller 2 and a voltage transformer 1 and a current transformer 3 connected in series at both ends. The explosion breaking device 4 is composed of explosives 4-9 and detonating devices 4- 2 is composed of metal busbars 4-8 and shunts 4-7. The detonating device 4-2 is connected to the controller 2. The controller 2 is a high-speed single-chip microcomputer controller, and a 40MHz single-chip microcomputer can be used. The explosive breaking device 4 has an insulating shell 4-1, and the metal busbar 4-8 and the shunt 4-7 are installed in the inner cavity 4-4 of the shell. The metal busbar 4-8 and the shunt 4-7 are separated by an insulating plate 4-6; both ends of the metal busbar 4-8 and the shunt 4-7 are ...

Abstract

The invention relates to a great current fast on-off apparatus, which mainly solves the problems of large volume of present breaker, long time in breaking fault, high cost, low accuracy of sampling, low reliability and high cost on maintenance. The explosion control system and the explosion on-off device, both of which are connected in parallel to the two linking ends of the main lines M1, M2, form said invention; the explosion control system is formed controller, voltage transformer and current transformer wherein the transformers are in cascade connection to the two ends of the system; the explosion on-off device is formed by metal master which contains dynamite and igniter apparatus, and one diverter, while the igniter apparatus connects to the said high speed single chip microcomputer controller. Said invention has low producing cost which is 10% of foreign products, simple maintenance expense, while it improves the on-off speed 20 times and the reliability 80% to present technique, therefore the fault area can be controlled effectively.

Description

Technical field [0001] The invention relates to an interruption protection device which can quickly and reliably cut off the faulty power supply, disconnect the power grid protection equipment and protect the power grid network when a short circuit occurs in the parallel of the generator outlet and the power grid. Background technique [0002] When a short-circuit fault occurs at the outlet end of the generator and the line equipment, due to the large short-circuit current (about 7-10 times the rated current of the generator), the source of the fault must be cut off at this time, otherwise the generator set or other electrical equipment will be seriously damaged. For the current grid connection of generators and power plants in my country, when a local short-circuit fault occurs, it should be immediately listed from the grid to avoid affecting the entire grid operation and avoiding the expansion of the accident. The traditional method is basically to use imported large-scale circ...
