With the adoption of the system, the current waveform at the time that the fault arc occurs or does not occur can be detected, and a controller determines, so as to determine the fault arc; the system is simple in structure, small in cost, simple to operate, and suitable for the condition of fault arc detection of large electrical equipments or circuits.
Description
Technical field
The invention relates to electric arc protection field, and especially a kind of novel power grid arclight detects and protection system.
Background technology
Along with the development of national economy, the net capacity of China is also in continuous expansion, and the scale of In the distribution system of low voltage also becomes large thereupon.But In the distribution system of low voltage changes of operating modes is fast, outlet is many, frequent operation, more easily think maloperation.And there is not stable problem in the bus of mesolow grade, does not generally install differential protection.Middle voltage bus bar running current is large, and fault overvoltage is high, device fabrication quality and safe distance poorer than high-tension apparatus, easily there is insulation fault.Switch cubicle arc short-circuit accident often occurred in recent years, even breaking out of fire, burnt transformer, finally developed into large power distribution network accident, caused great personnel's accident and economic loss.
Summary of the invention
The invention will solve the problem, and provides a kind of novel power grid arclight to detect and protection system, ensures the stable operation of electric system, and the arc generating device be furnished with arc protection device and automatically controlled, can detect arclight fast, effectively.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: novel power grid arclight detects and protection system, comprise arc generating device, D/A converter module, arc sensor, controller and man-machine interface, described arc generating device comprises fixed electorde, traveling electrode, firm banking, protective cover and axial drive means, described arc sensor is positioned at described protective cover, described controller is connected with described axial drive means, described fixed electorde is fixed on described firm banking by insulating blanked clamper gripping members, described traveling electrode is fixed on sliding shoe by described insulating blanked clamper gripping members, described sliding shoe by described axial drive means along described firm banking transverse shifting, described D/A converter module is connected by serial ports with described man-machine interface, described arc generating device is connected with described D/A converter module by universal serial bus mode.
Further, described arc sensor comprises temperature sensor, humidity sensor, infrared sensor and sonac.
Further, described fixed electorde is carbon-point.
Further, described traveling electrode is copper rod.
The advantage that the invention has and good effect are: novel power grid arclight detects and protection system; can to occur and do not break down electric arc time current waveform detect; judged by controller; determine fault electric arc; this detection is simple with protection system structure; with low cost, method of operating is simple, and the fault electric arc being suitable for extensive electrical equipment or circuit detects occasion.

Embodiment
As shown in Figure 1, novel power grid arclight detects and protection system, comprise arc generating device, D/A converter module, arc sensor, controller and man-machine interface, described arc generating device comprises fixed electorde 1, traveling electrode 2, firm banking 3, protective cover 4 and axial drive means 5, described arc sensor is positioned at described protective cover 4, described controller is connected with described axial drive means 5, described fixed electorde 1 is fixed on described firm banking 3 by insulating blanked clamper gripping members 6, described traveling electrode 2 is fixed on sliding shoe 7 by described insulating blanked clamper gripping members 6, described sliding shoe 7 by described axial drive means 5 along described firm banking 3 transverse shifting, described D/A converter module is connected by serial ports with described man-machine interface, described arc generating device is connected with described D/A converter module by universal serial bus mode.
Described arc sensor comprises temperature sensor, humidity sensor, infrared sensor and sonac.
Described fixed electorde 1 is carbon-point.
Described traveling electrode 2 is copper rod.
Described fixed electorde 1 is static contact, static contact be carbon-point not slidably, described traveling electrode 2 is moving contact, moving contact be copper rod slidably.In use, described traveling electrode 2 along with the sliding shoe 7 be connected with described axial drive means 5 along the horizontal slip of described firm banking 3, and then can adjust the distance between described fixed electorde 1.Described axial drive means 5 can be screw rod, can be also slide bar, by Electric Machine Control, also can pass through manual setter Non-follow control.An embodiment of the invention is that described axial drive means 5 passes through Electric Machine Control.The process of described motor is controlled by described controller.Distance between described fixed electorde 1 and described traveling electrode 2, when the coverage that electric arc produces, can produce smooth combustion electric arc, and now described arc sensor will collect trigger pip.Described triggering signal transmissions is to described controller.Described controller receives electric arc and produces signal, sends the signal of stopping action to described axial drive means 5.Described axial drive means 5 stops action, and then controls described traveling electrode 2 stopping slip.Owing to being furnished with described arc protection cover 4, prevent the arc spark produced in operation from splashing staff's accident such as initiation fire with it.Because contact is adjustable, slider can being driven slowly near stationary contacts by regulating described axial drive means 5, when there being sustained arc to produce, stopping sliding.The copper rod of moving contact and static contact and carbon-point are all dismountable, easy disassembly and maintenance.
Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the invention scope change and improve, and all should still belong within this patent covering scope.
