PTC is attached to Hermetic Compressor used for Refrigerator, Show Case and starts
Compressor for household refrigerator applies to
single
-
phase induction Motor.
For normal operation of the single-phase induction motor, in the starting operation flows
in both main coil and sub-coil. After the starting is over, the current in sub-coil is cut off.
The proper features of PTC play all the above roles. So, PTC is used as a motor starting
COMPOSITION
• PTC (Positive Temperature Coefficient) is a no-contact semiconductor starting device
which uses ceramic material and this material consists of BaTiO3.
• The higher the temperature is, the higher becomes the resistance value. These
features are used as starting device for the Motor.
NOTE FOR USAGE
• Be careful not to allow over-voltage and over-current.
• No Strike. If applying forcible power or strike (dropping or careless dealing), poor
operation and noise may occur.
•(3) Use proper electric components appropriate to the Compressor.
•(4) Note to Keep Compressor. If Compressor gets wet in the rain and rust in the pin of
Hermetic Terminal, the result may be poor operation and poor contact may cause.
•(5) Be careful that dust, humidity, and flux welding don't inflow in the Compressor
inside in replacing the Compressor. Dust, humidity, and flux due to welding which
inflows to Cylinder may cause lockage and noise.
NOTE TO USE PTC-RELAY
• Be careful not to allow over-voltage and over-current.
• No Strike, Don't apply a forcible power or strike.
• Keep apart from any liquid. If liquid such as oil or water away enter the PTC, PTC
materials it may break due to insulation breakdown of the material itself.
• Don't change PTC at your convenience. Don't disassemble PTC and mold. If the
exterior to the PTC-starter is damaged, resistance value is altered and it may cause
poor starting of the compressor motor may cause.
• Use a properly fixed PTC.
