I.Background
When using switch cabinets, people pay much attention to electrical temperature measurement. The switch cabinet temperature is too high mainly caused by the following reasons:
1)Reasons such as poor transportation and installation by workers will cause poor contact of the contacts. The increase in contact resistance will cause the temperature of the contacts to rise, which may burn out and power out.
2)Surface oxidation, loosening and aging of joints will occur during long-term operation, which is also one of the main reasons for equipment overheating and even serious accidents.
These reasons are inevitable, so the temperature monitoring of the switch cabinet is very important. However, the space in the switchgear is small, and the traditional temperature measurement method cannot meet the demand because the manual inspection cannot be performed. Acrel wireless temperature measurement system successfully solves this problem because it directly fixes the temperature sensor on the heat-prone parts, and then transmits the data to the server through wireless transmission, and can realize the function of over-temperature alarm.
II.Application
The customer is a Brazil cabinet company, the project has 90 three-phase circuit breakers in 20 cabinets, each cabinet is 800mm wide, so there is 16 meters of general bus and 90 circuit breakers connected to this general bus.
Acrel propose to use 270pcs temperature sensors ATE400 for circuit breaker, 60pcs ATE400 on bus, use 2pcs receivers ATC600-C to complete the wireless temperature monitoring system.
