Abstract
The utility model provides a tubular busbar monitoring devices, the present invention comprises an electric current transducer. Current sensor sets up on tubular busbar, and current sensor sets up on the earth connection of tubular busbar shielding layer for the leakage current on real -time supervision tubular busbar built -in electrical insulation layer, perhaps current sensor cup joints at tubular busbar outsidely for real -time supervision flows through the electric current of contact tube. The ageing monitoring problem in tubular busbar built -in electrical insulation layer has been solved to this tubular busbar current monitoring device to and real -time supervision flows through tubular busbar's electric current, refers to and the foundation for the transmission distribution of electric energy provides.
Description
Technical field
The utility model belongs to median and high voltage power system application, relates to a kind of tube type bus monitoring device, is mainly used in the leakage current of Real-Time Monitoring cast bus internal insulating layer and flows through the electric current of tube type bus contact tube.
Background technology
In modern power systems, tube type bus uses more and more extensive, and it is in operation and is responsible for the effect of transmission distribution electric energy.Because tube type bus requires steady in a long-term operation, but internal insulating layer can be aging, may occur the hidden danger that insulate, cause relative ground circuit etc., causes equipment scaling loss and large-area power outage.
All insulation protected type tube type bus surface requirements zero potential, therefore require very high to the insulating property of this series products, the power of its insulating property, is intuitively embodied in tube type bus leakage current values.Therefore, the security be in operation to protect product, must carry out Real-Time Monitoring to the insulating property of tube type bus.Meanwhile, answer Real-Time Monitoring to flow through the electric current of tube type bus, reference and foundation can be provided for the transmission of electric energy distributes.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of tube type bus current monitoring device, solve the aging monitoring problem of tube type bus internal insulating layer, and Real-Time Monitoring flows through the electric current of tube type bus, and the transmission for electric energy distributes provides reference and foundation.
The technical scheme solved the problem: the tube type bus monitoring device provided, comprises current sensor; Described current sensor is arranged on tube type bus.
Above-mentioned current sensor is arranged on the ground wire of tube type bus screen layer, for the leakage current of Real-Time Monitoring cast bus internal insulating layer, judges insulation course degree of aging.
Above-mentioned current sensor is socketed in tube type bus outside, flows through the electric current of contact tube for Real-Time Monitoring, judges Operation of Electric Systems situation.
Above-mentioned current sensor generally adopts centre path current sensor.
Above-mentioned current sensor by gather current signal transfer to monitoring host computer.
Advantage of the present utility model:
The utility model adopts current sensor, achieves the leakage current to tube type bus internal insulating layer and the electric current Real-Time Monitoring flowing through tube type bus contact tube, the security that protection product is in operation; Tube type bus current monitoring device can carry out data storage, intellectual analysis, gives warning in advance when accident potential produces, and effectively avoids the generation of accident.

Reference numeral is detailed as follows:
1-tube type bus dry outdoor terminal; 2-ground wire; 3-current sensor; 4-signal wire; 5-tubular bus connecting device; 6-tube type bus plugs with electric equipment and is connected terminal.
Embodiment
In conjunction with Figure of description, the utility model is described in detail:
As shown in Figure 1, Figure 2 and Figure 3, the ground wire 2 of tube type bus screen layer is separately positioned on tube type bus dry outdoor terminal 1, tubular bus connecting device 5 and tube type bus and plugs with electric equipment and be connected terminal 6 place.This tube type bus monitoring device, comprises current sensor 3; Current sensor 3 is arranged on tube type bus dry outdoor terminal screen layer, tubular bus connecting device screen layer or tube type bus and plugs with electric equipment and be connected on the ground wire 2 of terminal screen layer, by the leakage current situation of change of Real-Time Monitoring cast bus internal insulating layer, judge internal insulating layer degree of aging.Current sensor 3 generally adopts centre path current sensor.
As shown in Figure 4, at tube type bus outside socket current sensor 3, Real-Time Monitoring flows through the electric current of tube type bus contact tube, judges Operation of Electric Systems situation, and the transmission for electric energy distributes provides reference and foundation.
Principle of work of the present utility model:
First, on every bar ground wire 2 of tube type bus screen layer or tube type bus outside socket centre path current sensor; Then, the current signal transfer gathered by these current sensors by signal wire 4 is on monitoring main frame, monitoring main frame shows each check point electric current in real time, and remote server can be connected, if the impact being subject to monitoring of environmental also artificially directly can read current signal by RS485 or wireless mode as required.Corresponding leakage current threshold value can be set on the remote server, provide alarm by controlled by sound and light etc.
