Overview
CHANGLONG SW-100 (blue) temperature indicator is widely used in the connection part of the bus of the substation to monitor whether the contact at the connection of the bus is good. It is an indispensable protective item to ensure the safe operation of the substation. It can supplement the shortcomings of general thermometers. It can detect the excessive temperature rise of the bus in time during inspection to prevent accidents. It can also be used for equipment terminals, isolation switch contacts, transformers, motors, capacitors and other electrical equipment connected to the bus and non-electrical equipment such as bearings and bushings. Measuring temperature.
Features
1. Precision is high, and the error between the melting temperature of the temperature indicator and the rated temperature is +/- 1 ℃.
2. Good safety, allowing the melting of the temperature indicator to be observed away from the bus (or electrical equipment).
3. Easy to use, as long as the temperature indicator sheet is pasted on the bus and electrical equipment, its temperature can be monitored.
4. Intuitive, it is clear at a glance whether the temperature indicator is melted on the bus and electrical equipment.
Principle
The temperature indicator plate indicates the temperature through its melting characteristics. When the temperature of the bus or electrical equipment rises to the rated temperature (e.g. 100 ° C), the temperature indicator plate melts, thus directly displaying the temperature abnormality and facilitating timely processing.
Applications
Substation busbar connection parts, equipment terminals connected between busbars and electrical equipment, disconnector contacts, transformers, motors, capacitors and other electrical equipment, bearings, bushings and other non-electrical equipment
Steps
1. Paste the temperature indicator sheet on the bus or electrical equipment.
2. Make regular inspections to observe whether the temperature indicator is melted.
3. If melting is found, immediately handle the equipment accordingly (e.g. overhaul or load reduction).
