Fluorescent Fiber Optic Temperature Measurement System for Cable Splices in Ring Cabinets

Ring cabinet cable connector fiber optic temperature measurement system in the power grid applications

Power cables are widely used in the transmission and distribution of power systems for their durability, small footprint, and the advantages of laying in various situations. However, the ring network cabinet of its internal cable joints due to a variety of reasons is easy to heat, the degree of heat will affect the operation of the ring network cabinet itself and even the operation of the entire power grid safety. The high temperature of cable joints will cause serious oxidation, which will reduce the service life of cables; cause cable joint explosion, insulation breakdown, combustion and other hazards, resulting in large-scale power outages and fire accidents. In order to realize real-time online monitoring and alarm of cable joints, it is necessary to add temperature sensors to monitor the real-time temperature of cable joints.

Ring cabinet cable joints fiber optic temperature measurement system uses a fluorescent fiber optic temperature measurement device, the device's sensing probe metal-free materials using Innotek quartz fiber with complete electrical insulation, not subject to high voltage, strong electromagnetic fields, chemical corrosion resistance and non-pollution, and temperature probe through the company's processing to increase the temperature measurement area, can measure the temperature of the cable joints on the outside wall, and a fast response time, easy installation, high temperature resistance. It is easy to install and resistant to high temperature. At the same time, the system also provides remote web transmission, which is convenient for customers to install communication software and remote monitoring on any computer.

Fiber-optic temperature measurement of cable joints in ring main cabinet construction objectives

1) To establish a fiber-optic temperature measurement system for cable joints of ring main unit for automatic meter reading and tariff control, and to realize the functions of automatic meter reading and statistics of electricity data of the temperature measurement system software, remote login and access for automatic supplementary copying and copying, monitoring and remote control of temperature of cable joints of electricity consumption of each user, querying of electricity consumption of each user, and recharging of tariffs, so that it can grasp in real time the temperature of the cable joints of each ring main unit for each household's electricity consumption.

2) Users can log in to the WEB site of the centralized copying and temperature measurement system software to inquire about the real-time temperature of the bill payment, and historical data, details of outstanding bills and account balance.

3) Important meter failure information when the cable joint temperature exceeds the alarm value in time to issue an alarm to the inspector, the system administrator through the system to supervise the equipment, update the internal parameters of the equipment.

Design Principles of Fiber Optic Temperature Measurement of Cable Joints in Ring Cabinets

Practicality principle

The system construction adheres to the principle of practicality, on the basis of practical consideration of the advanced and forward-looking, the selection of standards-compliant, advanced and mature products and development platforms, to build a practical, practical problem-solving system.

Standardization Principle

Business applications are characterized by complex business, numerous processes, large amount of information and many levels of application. Through unified application function planning, a consensus on business operation is reached at the application level, and business units are guided to carry out business with unified standards.

At the same time, the system hardware and software platforms and application development tools used in the construction of business applications should comply with the national standards, the standards of the Ministry of Information Industry and the relevant technical specifications and requirements of the company.

Principle of Uniformity

Following the policy of centralized information management, integrated planning, overall design and step-by-step implementation, the implementation process reflects the four unified principles: unified leadership, unified planning, unified standards and unified organization and implementation.

Reliability principle

Hardware and software resources need to ensure that the cable temperature measurement system 7 × 24 hours uninterrupted, reliable operation, so it must be equipped with a perfect design of reliability measures to ensure a high degree of reliability of the system operation, giving full consideration to the reliability of the system's key applications.

Reliable security mechanism

The system adopts a series of secure encryption measures, built-in 64-bit encryption algorithm, the system's higher security can effectively prevent data leakage and theft, to ensure that the system's data security, accuracy and integrity, to prevent the operation of illegal operators and legitimate operators illegal operation. A system may have more than one operator to use, in order to ensure the security of the system, the implementation of hierarchical rights management. The system administrator authorizes operators to use different privileges, and each operator can only perform various operations within the scope of privileges, which makes the system more secure.

Simple and friendly operation interface with high degree of intelligence.

The system provides most of the default data needed in the operation process, and the operations are in line with the actual business workflow to avoid repeated operations by the operators. The system automatically checks the legitimacy of the input data, and provides friendly hints to the operator's misoperation.

Reasonable system structure design, high abstraction degree of program function module.

It can be flexibly configured according to the changes in the actual situation of users and the different needs of different users to maximize the satisfaction of users' needs. There are a variety of rate management, multi-type table management and other functions for users to better use the system.

The system adopts Web Service platform and B/S architecture design, which is in line with the trend of application development.

Stable operation, reliable data, thousands of systems in actual operation and more than 200 new projects every year.

The platform is easy to operate, easy to master, simple installation process. Data can be automatically generated according to the need for a variety of reports to improve management efficiency.
