Description

A new type of on-line monitoring device for SF6 gas leakage in the ring network cabinet

technical field

The invention relates to an on-line monitoring device for SF6 gas leakage used in the electric power industry, in particular to a novel on-line monitoring device for SF6 gas leakage of a ring network cabinet.

Background technique

After retrieving the relevant patent documents, a new type of on-line detection device for SF6 gas leakage of the ring main unit used in the ring main unit of the electric power industry with the same structure as the present invention has not yet been found. At present, the leakage of SF6 gas in the ring network cabinet of the power industry occurs from time to time. When SF6 gas contacts with the moisture in the air, some highly toxic substances will be produced, which poses a threat to the lives of the staff. Therefore, there have been some monitoring methods for SF6 gas leakage. The device is used to remind the staff to take preventive measures in time. Although the existing monitoring device has achieved intelligent monitoring and processing, the form of SF6 gas detection in the cabinet is relatively simple and the detection is not comprehensive. At the same time, the detection results are sometimes inaccurate. The staff knew about it at the first time, and the problem could not be solved quickly. Secondly, the internal CPU of the entire SF6 gas leakage monitoring device had to be manually upgraded regularly, and there was a lack of an online intelligent upgrade and archiving system. So it is necessary to improve the existing SF6 gas leakage monitoring device to meet the actual needs.

Contents of the invention

The purpose of the present invention is to provide a new type of on-line monitoring device for SF6 gas leakage of the ring network cabinet which is convenient to operate, safe and reliable, and detects the overall speed.

The technical feature of the present invention is: on the basis of considering the safety and accuracy of SF6 gas detection, it is designed to be a monitoring device, a wireless transmitter, an SF6 gas collector, a pressure sensor, an audible and visual alarm, a fan, and a cloud remote server. A new type of on-line monitoring device for SF6 gas leakage in the ring network cabinet. The SF6 gas collector and pressure sensor are installed inside the ring network cabinet. The wireless transmitter and the sound and light alarm are respectively installed on the cabinet of the ring network cabinet. The signal input terminal is connected with the signal output terminal of the SF6 gas collector and the pressure sensor through the transmission wire, the signal output terminal of the wireless transmitter is connected with the sound and light alarm through the transmission wire, the fan is set on the inner wall of the ring network cabinet, and is connected through the transmission wire. The wire is connected with the signal output end of the wireless transmitter.

The SF6 gas collector and pressure sensor are information collection and processing devices, which have the function of automatically collecting the SF6 gas concentration and the gas pressure value in the cabinet, and performing data processing and transformation functions, and are distributed in the ring network cabinet according to actual needs There are several.

The monitoring equipment is composed of a display unit, a main monitoring unit, a fan control module, and a GSM\GPRS module. The main monitoring unit receives the SF6 gas concentration information in the ring network cabinet sent by the wireless transmitter, and displays it on the display unit. The monitoring unit automatically or regularly starts the fan control module to drive the fan in the ring main unit to work.

The fan is a turbo fan.

The GSM\GPRS module is a radio communication device, used to transmit information to a remote server or mobile phone communication equipment.

The cloud remote server realizes the online upgrade of the main monitoring unit through the GSM\GPRS module.

When in use, the SF6 gas collector transmits the collected SF6 gas concentration to the wireless transmitter in the form of a signal, and at the same time the pressure sensor transmits the pressure data in the cabinet to the wireless transmitter in the form of a signal, and the wireless transmitter sends the signal sent to the monitoring equipment, the main monitoring unit processes and analyzes the received data, and displays the real-time data on the display unit. When the SF6 gas concentration exceeds the limit concentration, the main monitoring unit turns on the fan controller, and the wireless transmitter receives After the signal, start the fan to start working, ventilate the air in the ring network cabinet, disperse the SF6 gas, reduce the concentration, and start the sound and light alarm circuit to alarm at the same time, and the GSM\GPRS module will send the alarm signal to the mobile phone of the staff in the form of information, reminding The staff pays attention and takes corresponding measures. The detected data is then transmitted to the remote server through the GSM\GPRS module, and the data is summarized and archived.

The advantages of the present invention are: due to the arrangement of multiple SF6 gas collectors, the accuracy of SF6 gas collection is improved; due to the arrangement of pressure sensors, when the gas pressure in the ring network cabinet changes, it can also be adjusted Safe treatment is made; due to the setting of the fan controller, when the SF6 concentration is too high, the fan controller will drive the fan to work to reduce the SF6 gas concentration in the cabinet; due to the setting of the display unit, it is convenient for real-time observation and understanding of the SF6 concentration; Since the GSM/GPRS module is installed, the signal data can be transmitted through the network, which improves work efficiency; because the cloud remote server is installed, the main monitoring unit can be upgraded online, and the detected data can be saved and archived for future convenience. Call; due to reasonable structure, convenient use, safety and reliability, it has great practical and popularization value.
