Hangzhou Hansong Electric Co

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 isolate the following power supply system removable switch equipment, handcart corner fixed switch equipment Intelligent protection is provided for overheating caused by poor plugging, loose joints, creeping busbars, surface oxidation, galvanic corrosion, overload, excessive ambient temperature, poor ventilation, etc. at switch contacts, busbar cable connections, reactor windings, dry-type transformer high-voltage windings, etc. The switch cabinet wireless temperature measurement device is mainly suitable for online temperature measurement of the joint 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.
Two technical advantages of wireless temperature measurement device for switch cabinet
The wireless temperature measurement device for switch cabinet 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 switch cabinet wireless temperature measurement device has the advantages of accuracy, flexibility, ease of use, security, stability, low power consumption, real-time capability, wiring-free networking, flexible network capacity, large data wireless transmission, high wireless transmission, and fast response speed.
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 LAN and WAN of each system and integrate into the automated comprehensive control system. Corresponding interfaces are reserved to facilitate expansion and ensure future adaptability.
Safety
The independent installation of wireless transmission effectively avoids the influence of creepage and does not reduce the safety performance of electrical equipment.
Stability
The anti-interference housing design of high-quality sensor elements 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
Adopts 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 monitor up to 1 point online The temperature rise of the bits 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, the indicator light display value flashes, and three sets of passive relay output products provide interfaces and communication protocols that can upload environmental temperature and humidity to each monitoring point. information such as temperature and battery power.
The display mode of the temperature value of the switch cabinet wireless temperature measurement device can choose the temperature rise relative to the ambient temperature or the 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 as cooling or heating, 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, which is simple and intuitive to operate, and has an alarm record query function.
