Environmental intelligent management device for unattended substation control room

Abstract

The invention discloses a control room environment intelligent management device of an unattended transformer substation. An environment signal pickup circuit comprises a temperature acquisition circuit and a moisture acquisition circuit. A signal judging circuit comprises a temperature judging circuit and a moisture judging circuit. An execution circuit comprises a temperature execution circuit and a moisture execution circuit. Signal output ends of the temperature acquisition circuit and the moisture acquisition circuit are respectively connected with signal input ends of the temperature judging circuit and the moisture judging circuit. A signal output end of the temperature judging circuit is connected with a cooling appliance or a heating appliance of execution appliance devices through the moisture execution circuit. A signal output end of the moisture judging circuit is connected with a dehumidification appliance of the execution appliance devices through the moisture execution circuit. Temperature and moisture in the control room environment can be automatically adjusted and operating requirements of control devices and protecting devices are satisfied. The control room environment intelligent management device of the unattended transformer substation is reasonable in design, and has a positive guaranteeing function for power grid safe operation.

Description

technical field [0001] The invention relates to an environment management device for a control room of an unattended substation, in particular to an environment intelligent management device applied to the control room of an unattended substation. Background technique [0002] At present, with the rapid development of industrial and agricultural production, the rapid improvement of the national economy, the continuous improvement of people's living standards, the unprecedented development of the power industry, the national power grid construction is changing with each passing day. The power of the power grid is sent to the user after being transformed by the transformer of the substation. Due to the rapid increase of the construction of the substation, the power company implements the centralized control management of the substation in order to ensure the reliable operation of the power grid and improve the efficiency, which is a central station management. There are about ...

AI Technical Summary

Problems solved by technology

[0004] At present, the environment of the substation control room is manually controlled by the on-duty personnel, and the unattended substation is unattended. Due to the distance from the substation, it is difficult to adjust each time, so it is difficult to adjust in time, so it cannot meet the operation requirements of control and protection equipment. Control and protection equipment often Faults will directly affect the power supply, the equipment damage rate is high, and the power supply reliability is low
