Calculation of small automatic electric steam dual-purpose retort machine circuit breaker and copper core wire
JOOYAN Machinery's small automatic electric steam dual-purpose retort machine, without boilers, meets environmental protection requirements and is a good choice for small food enterprises.
There are three types of electric heating sterilizers available: 700 (0.6 cubic meters), 900 (1.4 cubic meters), and 1000 (2 cubic meters).
The corresponding power is 27KW, 54KW, 72KW.
In the process of using the electric steam dual-purpose retort machine, people often worry about selecting the power distribution equipment such as the copper core of the circuit breaker.
JOOYAN Machinery now introduces the calculation method as follows, for the reference of manufacturers of small automatic electric steam dual-purpose retort machine.
The following is an example of a minimum type 700 (diameter 700 mm, length 1200 mm) electric heating retort machine.
Current calculation: current = power / voltage / phase / power factor (usually 0.95)
That is, current = 27000/380/1.732/0.95,
About 43.2A can be used for 6 square copper core. For long-term use, for safety reasons, it is recommended to use 10 square copper wire voltage 380V, 27kw power current about 44A.
The rated current of the air switch is generally selected to be about 1.5-2 times the load current.
It is recommended to choose a 100A air circuit breaker, the choice is too small and easy to break.
Other small automatic electric steam dual-purpose retort machine models refer to this calculation.
