Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below, obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0031] This system is mainly used in large substations. The measurement and control devices are installed in outdoor switch cabinets, switch terminal boxes, PT terminal boxes, CT terminal boxes, various closed cabinets, fire pools, cable trenches and other facilities. Real-time monitoring inside the cabinet Temperature, humidity, and liquid level parameters, wirelessly send measurement data to the background, and at the same time, according to the fixed value set in the background, send an alarm signal and automaticall...

Abstract

The invention relates to a large-scale substation key facility monitoring system of a low-power wireless communication and a method. The system comprises an in-situ measurement and control device anda measurement and control background; the system further comprises a heater and a dehumidifier; the heater and the dehumidifier are installed in the closed cabinet of a substation; the in-situ measurement and control device is installed in the sealed cabinet, fire pool and cable trench of the substation; the in-situ measurement and control device monitors the temperature, humidity and liquid levelparameters of installation positions in real time and wirelessly transmits the temperature, humidity and liquid level parameters to the measurement and control background; and the measurement and control background starts and stops the heater or dehumidifier through the in-situ measurement and control device. Compared with the prior art, the system and method of the present invention can realizethe special monitoring of the key facilities of a large-scale substation.

Description

technical field [0001] The invention relates to the field of large-scale substation monitoring, in particular to a monitoring system and method for key facilities of large-scale substations based on low-power wireless communication. Background technique [0002] In recent years, with the strengthening of environmental pollution control in my country, the scope of clean energy applications has been continuously expanded, and the degree of substitution of electric energy has also been deepened. Due to the reverse distribution of my country's power generation resources and economic and population resources, large-scale hydropower, thermal power, wind power, solar power and other power resources in the southwest and northwest regions need to be transmitted to the economically developed and densely populated East China through ultra-high and ultra-high voltage transmission lines , North China and East China. At present, the voltage level of the power grid has been developed to AC...
