Description
Technical field
The utility model belongs to technical field of electric automation, relates to a kind of distribution electric wiring on-line monitoring cable head temperature or cable temperature is reported to the police and the fault alarm of distribution electric wiring indicates and the device of location.
Background technology
Safe operation for power system, the thermal fault detection of power system, the location of short circuit grounding fault is subject to people's attention, but it is the most time-consuming that the temperature monitoring of power system at present is monitored this mode by artificial timing infrared measurement of temperature to the temperature of end, do not have real-time, and live monitoring also has certain danger.To making a lot of hidden danger solve the most in time, ultimately cause electric power system fault.Existing fault location system the simplest short circuit and Earth design, do not possess monitoring-temperature alarm function yet, finds that solution ultimately forms significant trouble the most in time to making a lot of recessive hot stall.
Summary of the invention
The utility model solves problems of the prior art, provide a kind of distribution electrical circuit fault and temperature on-line monitoring device, it is characterised in that including: short-circuit sensor, temperature sensor, grounding sensor, communication cable, panel main frame and outside DC12V ~ 48V power supply composition；Wherein short-circuit sensor, temperature sensor are simultaneously attached on A phase cable, B phase cable and C phase cable, grounding sensor is arranged on cable bus, and short-circuit sensor, temperature sensor, grounding sensor are all carried out data transmission with panel main frame by communication cable.
Further, described panel main frame includes: front panel fixed frame, OLED LCDs, LED light, name of product, four button compositions；OLED LCDs display real-time current and temperature data, and actions menu shows, LED light indicates respectively the running status of current short circuit, ground connection, temperature, power supply and main frame, four buttons respectively corresponding-/downwards, determine/arrange ,+/ upwards, the button operation that returns.
The present invention uses current transformer direct power taking from cable to provide power supply, equipment is powered by high-capacity lithium battery as stand-by power supply, the temperature of phase current and cable uses phase sequence current transformer and temperature sensor to monitor in real time, is calculated by artificial intelligence and finally found that the recessive hot stall problem in power system and report to the police.By the failure condition of current detecting reaction power system, by rear whole software, trouble point is oriented in the calculating of topology.Temperature acquisition sensor is connected with display floater main frame by digital cable with short-circuit sensor.Finally solve the problems referred to above that power system exists.
The utility model be supporting be arranged in distribution network system loop networks switch, cable branch box, on box type transformer, for indicating the short circuit of respective cable section and single-phase earthing and a kind of real-time monitoring device of temperature fault.Line failure, staff can indicate by the warning of indicator, determine rapidly fault section, and find out trouble point.Meanwhile, warning message can be sent to the server of Surveillance center in real time, demonstrates region and the particular location of guilty culprit on the screen of monitoring computer, guides track walker determine rapidly fault section and find out trouble point.This indicator provides optimal path for solving fault-locating problem.To improving operating efficiency, shorten power off time, restore electricity rapidly, improve power supply reliability and economic benefit, have highly important meaning.
Accompanying drawing explanation
Fig. 1 is that distribution electrical circuit fault temperature on-line monitoring device of the present utility model installs wiring diagram；
Fig. 2 is distribution electrical circuit fault temperature on-line monitoring device Display panel figure of the present utility model.
Detailed description of the invention
As it is shown in figure 1, be that distribution electrical circuit fault temperature on-line monitoring device installs wiring diagram, it is made up of the outside DC12V ~ 48V power supply in 5 short-circuit sensors, 6 temperature sensors, 7 grounding sensors, 8 communication cables, 9 panel main frames and 10；5,6 it is simultaneously attached on 1 A phase cable, 2 B phase cables and 3 C phase cables, 7 are arranged on 4 cable buses, 5,6,7 by judging that the curent change on cable run judges that be short-circuited fault or earth fault, load current and fault-current signal of circuit all carries out data transmission with 9 by 8.
As shown in Figure 2, it is shown that distribution electrical circuit fault temperature on-line monitoring device panel of the present utility model, it is made up of front panel fixed frame 11, OLED LCDs 12, LED light 13,14, four buttons 15 of name of product；OLED LCDs 12 shows real-time current and temperature data, and actions menu shows, LED light 13 indicates respectively the running status of current short circuit, ground connection, temperature, power supply and main frame, four buttons 15 respectively corresponding-/downwards, determine/arrange ,+/ upwards with the button operation returned.
Native system is by signals such as each electric current, temperature in general purpose transducer (current sensor, temperature sensor etc.) collection power distribution network and is converted into DC 0mA to 5mA analog signals.The low-power scm chip that to access through holding wire on pcb board of analog signals of general purpose transducer output, and carried out Data Management Analysis by single-chip microcomputer and be converted into data signal and show in OLED liquid crystal screen.Retain the RS485 interface of communication and wireless radio interface for realizing and host computer or the communication of miscellaneous equipment on pcb board simultaneously.
Needed for native system, power supply is accessed by outside, and pcb board outer equipped with dustproof and waterproof shell for protection.
Being more than a most preferred embodiment of the present utility model, change or variation are likely made in this design in without departing from protection domain of the present utility model by those skilled in the art, but within these should be understood to still fall within protection domain of the present utility model.
