Abstract

The present invention discloses a junction box remote monitoring and early warning method. The method comprises a step of initializing each member, detecting whether the working of each member is normal or not, entering into a next step if the working is normal, and carrying out initializing again if the working is abnormal, a step of transmitting the data of a short circuit grounding fault sensor and a cable head to a wireless data collector, judging whether the short circuit grounding fault and cable head temperature exceed a predetermined value or not, entering into a next step if so, and continuing to collect data by the wireless data collector if not, and a step of transmitting a fault point to a server by the wireless data collector, and emitting alarm information by a server. The junction box remote monitoring and early warning method has the advantages that the cable head operation temperature real-time data and alarm information are provided for grid operation and maintenance personnel, the operation and maintenance personnel are helped to timely find the defect and risk in the cable head so as to timely carry out maintenance and disposal,, the cost of operation and maintenance and repair is reduced, and the labor intensity is reduced.

Description

Coupling box remote monitoring method for early warning
Technical field
The present invention relates to power monitoring field, be specifically related to coupling box remote monitoring method for early warning.
Background technology
For a long time, cable end overheating fault is puzzlement power equipment operational management work " old, large, difficult " problem always.In electrical network, all kinds of cable end quantity is many, widely distributed, and running environment is severe, and management difficulty is very large.The metal material used in high voltage power cable and insulating material are after temperature exceedes certain limit, its physical strength, dielectric strength can obviously decline, reduce its operation life, electrical equipment heating is even caused to damage, lead to a disaster, seriously have impact on the safe and stable operation of electrical network, cause great economic loss simultaneously.
Conventional artificial thermometric workload is large, poor real and be difficult to carry out effective monitoring to field personnel's operation behaviour.
Summary of the invention
The object of the present invention is to provide coupling box remote monitoring method for early warning, can effectively solve O&M cost high, occur that the overheated or short circuit of cable end can not the problem of Timeliness coverage.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: coupling box remote monitoring method for early warning, comprise Wireless data acquisition unit, short circuit grounding fault sensor, the cable end of built-in temperature probe and the server of distribution terminal, comprise the following steps successively:
A, first initialization is carried out to the server of distribution terminal, short circuit grounding fault sensor and cable end, detect short circuit grounding fault sensor and cable end whether working properly, enter next step if working properly, if it is abnormal to work, reinitialize;
The data of B, short circuit grounding fault sensor and cable end are transferred to Wireless data acquisition unit, judge whether whether earth fault and cable head temperature exceed predetermined value, if have earth fault or cable head temperature to exceed predetermined value, enter next step, if earth fault or cable head temperature do not exceed predetermined value, Wireless data acquisition unit continues image data;
The coordinate of trouble spot is sent to server by C, Wireless data acquisition unit, sends warning information by server.
Preferably, described short circuit grounding fault sensor and cable end are by ZiggBee and Wireless data acquisition unit communication; Adopt ZiggBee technical sophistication degree low, and low in energy consumption, cost is low, is applicable to widespread adoption.
Preferably, the built-in passive type radio temperature sensor of described cable end and wireless signal transmitter; Adopt electric field induction way to take power, by directly measuring fully-sealed electric cable joint inner conductive terminal and bushing conductor Contact Temperature, and the thermometric product of temperature information is sent by communication, and carry the functions of the equipments detecting short circuit and earth fault, not only increase the security of product, also provide convenient and high-level efficiency.
Preferably, described Wireless data acquisition unit is connected with server by wired mode; Specifically can adopt as RS485 communication interface, by suitable communication network and RTU device by the on-line temperature monitoring information integerated of cable accessory in Power SCADA system, in the interface display of SCADA system, be used for the temperature information of monitoring analysis cable accessory.
Compared with prior art, advantage of the present invention is: adopt short circuit grounding fault sensor and cable end automatic data acquisition, then the Wireless data acquisition unit of each node is sent to, judge that whether current data is normal by Wireless data acquisition unit, again the coordinate of abnormal data is sent to server if abnormal, warning information is sent by server, notice operation maintenance personnel is overhauled, for electrical network operation maintenance personnel provides cable end running temperature real time data and warning information, help the defect existed in operation maintenance personnel Timeliness coverage cable end, hidden danger, to safeguard in time, dispose, realize cable end O&M pattern by the change of passive repairing to active defect elimination, reduce O&M, emergency repair cost and personnel labor intensity, be conducive to carrying out effective management and control to new production cable end processing quality, effective prevention cable end hot stall causes the generation of equipment burning damage accident, guarantee power network safety operation, reduce the generation of user's power-off event, promote good service level, because of other societies that operation of power networks capability improving brings, economic benefit is huge, the functions of the equipments being used for detecting short circuit and earth fault carried, improve the function of product greatly, save the time of trouble shooting, improve work efficiency.
