Abstract
The invention discloses circuit equipment, which is correspondingly connected with a cable and distribution equipment according to the voltage of the cable and the distribution equipment, and can be used for sampling the cable and the distribution equipment, automatically and intelligently analyzing and judging data, automatically controlling the on/off, analyzing faults of the cable or the distribution equipment and automatically uploading a fault report, alarm information and data of the cable and the distribution equipment to a power safety wireless monitoring network, thereby monitoring, controlling and maintaining the cable and power equipment. From view of the quantity of application equipment, the invention makes the defending of the cable and the distribution equipment with few people or without people possible.
Description
Affiliated technical field
The present invention is the terminal monitoring equipment that is connected with power transmission cable with controller switching equipment in a kind of power transmission system.At the electric power safety wireless monitor network of cable and controller switching equipment, the terminal of closing functions such as lock is closed in its status monitoring that carries out, burglar alarm and control implement.
Background technology
Along with the development in city, the electric power safety construction more and more concerns normal operation and masses' normal life work in city.Existing safety detection and method for maintaining utilize artificial inspection that cable is made regular check on manually to make regular check on and the interim troubleshooting of accident after taking place exactly, are reconnoitred by the scene.This method is the discovering device problem in time, more can't in time go out reaction to the risk of disturbance that exists, and is more at a loss what to do for the situation that cable is stolen, and consumes the great amount of manpower financial resources.Simultaneously, the potential faults of power equipment causes great obstruction to the city normal operation.
Along with city's constant development, control range is increasing, makes that maintenance and monitoring are very difficult.Fault in the running has only the tour of wait personnel to reach the spot and could find, cable breaks down or stolen and can only wait for civic phone reflection usually passively, is difficult to accomplish timely maintenance, and the pilferage incident is difficult in time take precautions against in inspection.
Summary of the invention
For complying with the urban development needs, through long research, we have developed a kind of terminal monitor of electric system.This equipment can carry out electric current, voltage power and power factor to connected cable and distribution box and carry out state analysis.Terminal monitor of electric system is assigned closed lock order by carrying out Trouble Report and alarm report with electric power safety wireless monitor network to administrative department by administrative department.From the angle of application apparatus quantity, make cable and controller switching equipment few man on duty or unattended operation become possibility.
The technical solution used in the present invention is: terminal monitor of electric system is installed on the cable of controller switching equipment and per 200 meters length, according to its electricity ginseng specification a terminal monitor of electric system that matches is installed.By AD chip, CPU and Acquisition Circuit, the data such as electric current, voltage, power and power factor of cable or controller switching equipment are gathered, analyzed and store, convey to connected Communication Control chip with the form of digital signal.By communicating circuit, CPU and filter circuit the data that Acquisition Circuit and AD chip transmit are analyzed and stored, and with data by antenna transmission to the electric power safety wireless control network, carry out Trouble Report and alarm report, send instruction by CPU and interlock circuit to relay simultaneously, carry out closed lock action.By clock chip and crystal oscillator in the electric system terminal monitor, the time closing lock of may command relay moves in addition.
The invention has the beneficial effects as follows, by terminal monitor of electric system is installed, can accurately carries out condition monitoring, closed lock control, Trouble Report and alarm report to cable or controller switching equipment and upload.Thereby monitoring, control and antitheft demand have been satisfied to cable and controller switching equipment.Make cable and controller switching equipment few man on duty or unattended operation become possibility.

Embodiment
In figure one, terminal monitor 2 one ends are connected 1 with cable, perhaps are installed in the controller switching equipment 3.
Terminal monitor 2 is connected with cable 1 in Fig. 1, and terminal monitor provides power supply by power-supply system 13.Gather by the data such as electric current, voltage, power and power factor of 10 pairs of cables of AD acquisition chip group or controller switching equipment through voltage transformer 4 summation current transformers 5.Again image data is passed to CPU and external circuit 9 with digital signal form, data are analyzed and stored by CPU and external circuit.And transfer data to filter circuit 12, and send to the electric power safety wireless control network by it by antenna 6, carry out Trouble Report and alarm report, send instruction by CPU and external circuit 9 to relay 7 simultaneously, carry out closed lock action.In addition also can be by clock chip 11 and the crystal oscillator 8 in the electric system terminal monitor, the action of the time closing lock of control relay 7.
(annotating: when terminal monitor 2 is installed in the distributor relay 7 is installed, is not needed relay 7 when being connected) with cable 1
