Overload alarm system for electric power voltage detection

Abstract

The invention discloses an overload alarm system for electric power voltage detection. The overload alarm system comprises a PCL control system, an information collecting and processing device, a fault electric arc collecting device and a protocol conversion module in two-way connection with the PCL control system. The protocol conversion module is in two-way connection with an electric power fire hazard monitoring device. Based on a protocol control principle, the protocol module and the electric power fire hazard monitoring device are arranged and can further collect electric leakage, currents, voltage and other electric power parameters on site as well as short-circuiting, overloading, overvoltage, undervoltage, a phase failure and other fault information on site, the electric power parameters and the fault information are converted into corresponding data formats through the protocol conversion module and transmitted to a remote monitoring terminal through the PCL control system, the remote monitoring terminal performs reading, protecting, monitoring and analyzing according reflected data, and alarm, setting and control information is transmitted to the electric power fire hazard monitoring device through the PCL control system. The overload alarm system is reasonable in design and can prevent and process electric power voltage overload.

Description

technical field [0001] The invention belongs to the technical field of voltage detection, and in particular relates to a power voltage detection overload alarm system. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, people's demand for electric energy continues to increase, and the requirements for safe power supply are also getting higher and higher. The formation of large-scale and integrated national power grids; the gradual enhancement of inter-regional interconnection; the continuous increase of stand-alone capacity and total system capacity; the formation of large-scale power systems; the construction of new energy power systems; appear; making the structure and operation of the power system more and more complex. The complexity of the power system directly threatens the safe and stable operation of the system. Some local disturbances may lead to blackouts or sharpen the stability of ...
