Product Description
1. Product Overview
The LHRX1908 substation integrated on-line monitoring system adopts a hierarchical and distributed field bus structure and consists of a monitoring system installed in the substation and a data management system installed at the user end. It can implement on-line monitoring and diagnosis of the insulation status of high-voltage electrical equipment such as CT, CVT, coupling capacitors, bushings, and lightning arresters. Users can collect the monitoring data of several substation monitoring systems to the data management and diagnosis center through the LAN.
The company provides a comprehensive online monitoring system solution, which is widely applicable to substations and power plants with 110kV and above voltage levels. It integrates various equipment status parameters such as electrical quantity, non-electricity quantity, stability and transient in the power station. Each monitoring subsystem is based on a unified network structure and background management system.
2. Functional characteristics
1. Flexible configuration: A distributed design structure is adopted. The configuration of monitoring equipment and monitoring items does not need to change the system structure. Different types and quantities of local monitoring units can be connected to the fieldbus provided by the central monitoring unit as required to realize monitoring and diagnosis of electrical equipment such as transformers, transformers, coupling capacitors, lightning arresters, bushings, GIS, circuit breakers, etc.
2. Easy installation: only need to install the local monitoring unit under the electrical equipment under test, and the measured signal communication cable is hooked up to the fieldbus provided by the central monitor.
3. High precision, high stability: the use of high precision and high stability of zero flux transformer to ensure the accuracy and stability of capacitive equipment dielectric loss measurement and lightning arrester equipment resistance current measurement.
4. Analysis and processing capacity: The data management system adopts a large database and has strong analysis and diagnosis functions. It can analyze electrical equipment with abnormal insulation parameters according to monitoring data, issue an alarm, and automatically generate relevant monitoring information and monitoring reports including change trend charts of insulation parameters.
5. Simple maintenance: The local measurement unit adopts modular structure design, with good versatility and interchangeability, and can be repaired or replaced without affecting the operation of the equipment, including the sensor. The system is easy to expand and has strong compatibility.
6. The status monitoring information of all high-voltage equipment is stored in the local office, and each station independently saves the monitoring information, and the two-level online monitoring system can operate independently.
7. Provide a comprehensive online monitoring system solution, which is widely applicable to substations and power plants with 110kV and above voltage levels, covering almost all high-voltage equipment, integrating the electrical quantity, non-electricity, steady state, transient state and other equipment status parameters in the power station, and each monitoring subsystem is based on a unified network structure and background management system.
3. Technical indicators
The LHRX1908 monitoring system consists of a background management and diagnostic system (server), a central monitor (host) in the station and a number of local monitoring units (intelligent sensors) with different functions. According to the monitoring requirements, local monitoring units with different functions and quantities can be selected to flexibly form a special monitoring system for certain electrical equipment.
4. System composition
The LHRX1908 electrical equipment condition monitoring and fault diagnosis system consists of two parts: the monitoring device installed in the substation and the data management system installed at the user end. Through the LAN, the user can put a number of substation monitoring system monitoring data, collected to the data management and diagnosis center and integrated management.
