Detection controller for operating environment of secondary device

Abstract

The invention, which belongs to the operation and maintenance control field of the transformer substation, discloses a detection controller for an operating environment of a secondary device. The detection controller is composed of a central control module, a sensor interface module, various environmental detection sensors, a driver module, a modem, an omni-directional antenna, a directional antenna and a secondary device environment monitoring device for a central station. The various environmental detection sensors is connected with the central control module by the sensor interface module; the output terminal of the central control module is connected with the input terminal of the driver module; the output terminal of the driver module is connected with a controlled device; and a communication terminal of the central control module is in bidirectional connection with the modem connected to the omni-directional antenna. The omni-directional antenna carried out communication with the directional antenna arranged on the secondary device environment monitoring device for a central station. The detection controller has the following advantages: the reaction is sensitive; 24 / 7 monitoring and recording can be carried out on the indoor environment temperature and humidity and the indoor environment temperature and humidity can be uploaded in real time; if the monitored information exceeds a set critical temperature value, a set critical humidity value or a set critical smoke value, the information is recorded automatically and is fed back to the secondary device environment monitoring device for a central station.

Description

technical field [0001] The invention relates to a secondary equipment operating environment detection controller, which belongs to the field of substation operation and maintenance control. Background technique [0002] After the substation is unattended, it is difficult to monitor the environment of the secondary equipment room such as the protection room and the communication room. Due to the wide distribution of the secondary equipment room, new requirements are put forward for the scale and coverage of the information communication network. If the environment is not monitored, it is very unfavorable to maintain the safety of secondary equipment and substations. [0003] Most of the existing secondary equipment environments have the following problems: [0004] When the indoor humidity of the secondary equipment is too high, it is easy to cause the equipment with poor sealing performance to get wet. Once the secondary equipment gets wet, the internal circuit will be shor...

AI Technical Summary

Problems solved by technology

[0004] When the indoor humidity of the secondary equipment is too high, it is easy to cause the equipment with poor sealing performance to get wet. Once the secondary equipment gets wet, the internal circuit will be short-circuited or even burned. Most of the secondary equipment is made of metal products, which are easy to rust and often lubricated. Most prone to problems during downtime

[0005] Since all kinds of electrical components have different heat release during work, the temperature rise in the substation or power distribution room is more obvious, and the higher temperature will greatly affect the operation safety of electrical equipment. At the same time, in the substation or power distribution room In addition to the temperature factor in the room, the humidity also greatly affects the safe operation of electrical equipment. When the humidity is high, it is easy to cause leakage accidents in the equipment. Therefore, air conditioners and axial fans are currently installed in power stations or power distribution rooms. , electric furnace wire and other cooling equipment to ensure the stability of the indoor temperature, but these traditional equipment are independent operation and their use requires human input, the response time is long, and power supply accidents caused by human errors are prone to occur, especially in modern In unattended power distribution rooms or substations, traditional cooling and dehumidification systems cannot meet the needs of safe electricity use and users
