TECHNICAL FIELD

[0002] In the operation process of hydropower station, primary equipment as the key equipment of electric energy production, transformation, transmission and distribution, the stability and reliability of its operation state directly affect the power generation efficiency and power supply quality of the whole hydropower station, and the primary equipment includes generator, transformer, circuit breaker, disconnecting switch, bus etc., these equipment is in complex operation environment for a long time, faces the influence of electrical stress, mechanical stress, thermal stress and environmental factors etc., and is prone to failure.

[0003] At present, the traditional hydropower station primary equipment monitoring mode has many deficiencies, on the one hand, the monitoring system often adopts the structure of dispersion, each monitoring module runs independently, lacks effective integration and cooperation, leads to scattered monitoring data, is difficult to unified analysis and management.This not only increases the work burden of operation and maintenance personnel, but also reduces the accuracy and timeliness of fault diagnosis. On the other hand, the existing monitoring device mostly monitors single equipment or single parameter, and cannot comprehensively and comprehensively reflect the overall operation state of primary equipment. For example, for the monitoring of generator, only the electrical parameters such as voltage and current are concerned, and other important parameters such as temperature and vibration are ignored, which makes it difficult to discover some potential faults in time. In addition, with the continuous expansion of hydropower station scale and the replacement of equipment, the expansibility of traditional monitoring device is poor, and it is difficult to meet the monitoring demand of new equipment and new function, if the monitoring system is upgraded, a large amount of manpower, material resources and time cost is often needed.

[0004] At present, in order to achieve better modular monitoring effect of hydropower station primary equipment, usually a plurality of corresponding sensors are installed on the hydropower station primary equipment, through the cooperative work of multiple types of sensors, the electrical parameters, temperature, vibration and other aspects of data of primary equipment can be comprehensively collected, the all-round monitoring of equipment operation state is realized, the potential fault hidden danger is discovered in time, the accuracy and reliability of fault diagnosis are improved, and the modular monitoring effect is achieved.

In view of this, we propose a modular monitoring device for hydropower station primary equipment. UTILITY MODEL CONTENTS
