Water pump temperature measurement system intelligent substation temperature measurement switch cabinet temperature measurement sensor

>The switch cabinet wireless temperature measurement device adopts the internationally advanced wireless sensor network technology, with an intelligent microprocessor as the core, and uses a precise digital temperature sensor to measure the following power supply system removable switchgear handcart corners , fixed switchgear isolating switch contacts, busbars, cable connections, reactor windings, busbar pictures, dry-type transformer high-voltage windings, etc. due to poor plugging, loose joints, busbar creep, surface oxidation, galvanic corrosion, overload, environmental Intelligent protection against overheating caused by excessive temperature or poor ventilation.
>Switch cabinet wireless temperature measurement device is mainly suitable for online temperature measurement of joints, contacts and busbars of various types of indoor high-voltage switchgear. There is no electrical connection between the secondary part and the primary part of the wireless temperature measurement device in the switch cabinet. Information exchange between the sensor and the host is transmitted through wireless signals, which will not affect the insulation performance of the system and is safer to use.
>2. Technical advantages of switch cabinet wireless temperature measurement device
>Switch cabinet wireless temperature measurement device is a temperature measurement system for switch cabinets developed based on wireless temperature measurement technology. The wireless temperature measurement device of the switch cabinet has good sealing performance, and the wireless temperature measurement device of the switch cabinet can be used safely both indoors and outdoors. The wireless temperature measurement device for switch cabinets has the characteristics of accuracy, flexibility, ease of use, safety, stability, low power consumption, real-time, no wiring, flexible networking, large network capacity, high data wireless transmission, and fast response speed. and other advantages.
>Accuracy
The imported high-precision digital temperature sensor adopts contact temperature measurement, which is very close to the heating point and can quickly and accurately monitor the temperature changes at the temperature measurement point.
>Flexibility
Small size, easy installation, flexible networking, wired or wireless, convenient for increasing the number of monitoring points.
>Ease of use
Based on an excellent operating platform, it adopts modular design and is easy to operate. It is convenient to connect to the local area network and wide area network of each system and integrate into the automated comprehensive control system. Corresponding interfaces are reserved to facilitate expansion and ensure future adaptability.
>Safety
Wireless transmission and independent installation effectively avoid the influence of creepage and do not reduce the safety performance of electrical equipment.
>Stability
High-quality sensor components, anti-interference housing design and advanced program encoding and decoding verification functions ensure that the sensor operates stably and reliably in complex environments.
>Low Power Consumption
Low power consumption design extends the service life of the sensor while ensuring normal temperature measurement.
>Real-time
It can automatically monitor the temperature changes of key points in the equipment online, and the temperature will display the advantages of the system in real time.
>No wiring
Using wireless data transmission, internal battery power supply, wireless temperature sensor node installation Simple three switch cabinet wireless temperature measurement device function description
>The switch cabinet wireless temperature measurement device can be monitored online at most The temperature (temperature rise) of each point is transmitted wirelessly and displayed in real time on the screen of the host. The host monitors the temperature of these monitoring points in real time.
>When the temperature of any monitoring point exceeds the set temperature It will output three levels of alarm prompts (indicator lights, display value flashing and three sets of passive relay outputs). The product provides interfaces and communication protocols, and can upload information such as ambient temperature and humidity, temperature of each monitoring point, and battery power.
The display mode of the temperature value of the wireless temperature measurement device in the switch cabinet can be selected as temperature rise (relative to the ambient temperature) or actual temperature. The host computer can set and read the parameters of the instrument through the interface, as well as collect data.
> The switch cabinet wireless temperature measurement device can also independently choose to control the temperature or humidity of the environment. For the load relay, you can choose to use a set of relays for temperature and humidity, or you can choose to share a set of relays. The working mode of the temperature control load can be selected to cool down or heat up. , while the humidity control load can only use the heating or dehumidification mode.
The switch cabinet wireless temperature measurement device adopts a graphical Chinese menu interface, the operation is simple and intuitive, and has an alarm record query function.
