Abstract

The invention discloses an intelligent load limiting controller, comprising a processor, a load controlling relay which is connected to a processor, a temperature detector connected to the processor, a phase detector connected to the processor, a current detector connected to the processor, a voltage detector connected to the processor, and a power supply connected to the processor. The intelligent load limiting controller can overcome a shortcoming that a malignant load identification device on the market is simple in function and easy to crack, reduces workload of staff, and effectively prevents electric safety accidents from happening.

Description

technical field [0001] The invention belongs to the field of protection devices for safe use of electricity, and in particular relates to an intelligent load-limiting controller. Background technique [0002] There are currently two types of load recognizers on the market. One is very simple and based on current detection, that is, the power will be cut off if the current exceeds a certain value. Then simply think: P = UI = 220V × 10A = 2200W = 2.2KW, the formula: power = voltage × current, that is, if the power of a certain electrical appliance exceeds 2.2 kilowatts, then the power will be cut off immediately. This kind of load identifier simply identifies the current, does not judge the load type, and does not calculate the power according to the influence of the power factor. There is almost no control at all, and it only controls the output power simply and crudely. If the current limiting current set by the load recognizer is too small, some high-power electrical appli...
