Problems solved by technology

If the location where the ice machine is located has insufficient margin or no reserved line in the power distribution design, it will often compete with the existing electrical appliances for power on the existing line, resulting in a drop in power supply voltage, etc., so that the ice machine It enters the protection standby state and cannot be started. Due to the non-standard application of ice machines, ice machine manufacturers have not yet provided an effective solution to this technical problem.

[0017] Table 1: Ice machine power supply circuit configuration table

[0018] illustrate:

[0019] 1) Table 1 is specially configured for the ice machine (single-phase power supply, soft ice machine, hard ice machine), and its cable must have at least 3 cores (each core is copper multi-strand): L phase line + N neutral line + PE protective grounding ;

[0020] 2) When measuring the electricity bill of the ice machine, configure an electric meter with 20A or above;

[0021] 3) When the power grid voltage in this area is not stable, a 5KVA power regulator should be installed at the power socket in front of the ice machine.

[0022] In Table 1, if other electrical appliances have to be added to the power supply line, please refer to the following method for conversion:

[0023] Taking the added electrical appliances of 1000-1200W as an example, first calculate the conversion coefficient k=1+total power of added electrical appliances / rated input power of ice machine...

Abstract

The invention provides a method for configuring power supply lines of a single-phase source ice cream maker, comprising the step of configuring a line from a distribution center to a distribution box and the step of configuring a line from the distribution box to a power socket. The invention solves the blindness of the single-phase source ice cream maker users on line configuration, scientifically, concisely and easily guides the ice maker users to consult and implement the method, and furthest ensures the normal working of the ice maker.

Description

technical field [0001] The invention relates to a method for configuring a power supply circuit, in particular to a method for configuring a power supply circuit for an ice machine. Background technique [0002] According to the basic requirements of IEC and national standards for the power supply voltage of electrical equipment and the general requirements of the same industry, the working range of the ice cream machine power supply voltage is + / -10% near the nominal voltage, which is 198-242V in mainland China. This requirement is followed in the design and production of the ice machine, which is actually a condition for the normal operation of the ice machine: when the ice machine is turned on, if the power supply voltage is not within the aforementioned range for a long time, it will not be able to enter the normal working state; When the ice machine is working, if the power supply voltage does not meet the conditions, the ice machine will quit working and enter the prot...
