Integrated monitoring apparatus for electrical power distribution

Abstract

The invention provides a power distribution comprehensive monitoring device suitable for power systems, the device includes a central processing unit, an AC sampling module, a temperature measurement module, a condensation measurement module, a reactive power compensation output module, a relay output module, a communication module, a storage module, man-machine interface module. The AC sampling module, the storage module, and the man-machine interface module are respectively connected to the data bus of the central processing unit, and are controlled by the central processing unit; the temperature measurement module and the condensation measurement module are connected to the input port of the central processing unit; reactive power The compensation output module and the relay output module are connected to the output port of the central processing unit; the communication module is connected to the communication port of the central processing unit. In addition to conventional electric parameter acquisition and reactive power compensation functions, the device also has temperature and humidity measurement and control functions.

Description

technical field [0001] The invention relates to a power distribution monitoring device used in a power system, in particular to a power distribution monitoring device with temperature and humidity measurement and control functions. Background technique [0002] The box-type substation has the characteristics of compact structure, strong complete set, small footprint, convenient installation and maintenance, and beautiful appearance. Box-type substations are generally placed outdoors, and the surrounding environment is relatively harsh, and the temperature and humidity inside the box are greatly affected by the environment outside the box. If condensation occurs in the high-voltage room and the low-voltage room, it will endanger the electrical insulation and cause breaking failure. If the temperature of the transformer exceeds one degree, it will affect the output power. In severe cases, it will cause abnormal operation of the transformer and increase the pressure inside the...

AI Technical Summary

Problems solved by technology

Additional temperature and humidity monitoring devices need to be installed in the substation, resulting in a large number of instruments, which not only increases investment, but also increases the workload of wiring and maintenance due to the compact structure of the box-type substation

Moreover, the current power distribution terminals do not realize the real-time monitoring of the state of the transformer pressure relief valve, the detection of the opening and closing of the door, and the control of the air change.
