Price of wireless temperature measurement online monitoring system

Description :

　　Hongjiang Power Plant is equipped with 6 single 45MW bulb tubular units, with a total installed capacity of 270MW. When put into operation, it was a domestic single capacity bulb tubular unit. The factory voltage used in the power plant is 400V, and the original 400V low-voltage circuit breaker cabinet is a low-voltage GCY type combination withdrawable switchgear produced by Henan Xinxiang Yubei Electrical Appliance Factory, which has been in operation for 13 years. With the extension of operating years, equipment continues to age, and in recent years, there have been frequent occurrences of poor contact between circuit breaker connectors and busbars, as well as overheating and deformation of circuit breaker connectors under high loads. Previously, there was no specialized 400V high current circuit breaker temperature measurement equipment in the power plant. The above defects were discovered through manual temperature measurement three times a day. As they were not monitored continuously for 24 hours, the discovery of these defects had a certain lag time. In addition, there are many detection points and complex detection locations, making manual temperature measurement time-consuming and laborious, and even threatening the personal safety of temperature measurement personnel.

　　In the second half of 2014, Hongjiang Power Plant decided to renovate the 400V low-voltage system used in the utility plant. In order to improve the automation level of equipment, achieve 24-hour uninterrupted online monitoring, automatic alarm, reduce manual temperature measurement workload, and prevent factors such as electric shock safety risks during manual inspection and temperature measurement, a "temperature online monitoring device+wireless temperature measurement technology" is adopted to achieve real-time temperature monitoring of the 400V low-voltage system for factory use.

　　The wireless temperature measurement system consists of an acquisition layer, a collection layer, and a monitoring layer as a whole. The collection layer is composed of wireless temperature sensors; The collection layer is an on-site centralized display device, connected wirelessly to the collection layer, and connected to the monitoring layer through a network or fiber optic cable; The monitoring layer is the temperature measurement backend, which can be connected to the network through communication methods such as 10/100M LAN and fiber optic network. The system manages the collected data and stores it in the database at regular intervals. It records the information in the real-time database according to user requirements, forming a historical database that can provide display of minute, hour, and day curves, report printing, overheating records, and timely alarm signals; Support data sharing, provide third-party access to temperature measurement data, and put the temperature measurement data into the comprehensive management platform

　　The application and promotion of wireless temperature measurement devices in ring main units is a trend and a major achievement of innovation. The application of the Ankerui wireless temperature measurement device introduced in this article in the ring main unit can achieve the integration of operation and display, and can monitor the temperature incoming lines of the busbar, circuit breaker upper and lower contacts, cable joints, etc. in the cabinet online. It can prevent the risk of overheating caused by excessive contact resistance due to oxidation, loosening, dust and other factors during operation, improve equipment safety guarantee, timely, continuously and accurately reflect the operating status of the equipment, avoid safety accidents, and reduce equipment accident rate.

　　After the wireless temperature sensor measures the temperature at the monitoring point, it transmits the temperature data wirelessly to the wireless temperature measurement terminal; Through bus connection, the temperature monitoring computer collects the operating temperature data of each monitoring point from the wireless temperature measurement terminal, stores it in the database for a long time, displays the temperature change curve of the monitoring point in real time, and analyzes it. Once the temperature is found to be overheated or rapidly rises to the pre-set alarm temperature value, it will immediately sound an alarm. At the same time, it is convenient to connect the upper computer with temperature data to the network for web publishing. The wireless temperature measurement device temperature measurement terminal can be set with two temperature alarm values. If the temperature exceeds the alarm setting value, it can drive the buzzer. The application of this system is divided into two aspects: civilian and industrial applications. Civil applications are mainly suitable for the field of room temperature monitoring; Industrial applications are mainly suitable for fields such as power, steel, petrochemicals, etc. It can monitor the temperature of high-voltage cable joints and high-voltage switchgear contacts in real time, making it convenient for operation and maintenance personnel to remotely grasp the on-site operation situation.
