Three-phase intelligent energy-saving protection control socket

Abstract

The invention relates to a three-phase intelligent energy-saving protection control socket. An input end of a three-phase live wire in a socket shell is connected with current transformers respectively and is connected with an input end of a detection display control unit; an output end of the detection display control unit is connected with a display screen; transient surge suppression units are respectively connected between the input end of the three-phase live wire and an earth wire; the input end of the three-phase live wire is sequentially connected with a voltage regulation unit, a filtering compensation unit and a controlled switch; an input end of the controlled switch is connected with a control output end of the detection display control unit; an output end of the controlled switch is connected with a three-phase jack on the socket shell; two contactors are connected between two input ends of one-phase voltage regulation units by a bypass switch. The socket effectively removes such power wastes as transient, surge, harmonics and the like, increases the power factors, reduces the surplus energy consumption, eliminates the standby power consumption, has the characteristics of high power saving ratio and cost performance, complete functions, intelligence, flexibility and the like and can be widely applied to three-phase AC power systems.

Description

technical field [0001] The invention belongs to the field of power-saving protection and control, in particular to a three-phase intelligent power-saving protection and control socket. Background technique [0002] At present, power waste and excess energy consumption are common problems in power consumption systems or power consumption equipment, resulting in waste of power resources and damage to power consumption equipment. Among them, there are three main reasons for the waste of power resources: (1) the existence of Power waste problems such as transients, surges, and harmonics, (2) there is a problem of excess energy consumption of the power system or power equipment exceeding the rated voltage, (3) there is a problem of standby energy consumption of power equipment. It is precisely because of the above problems that the power consumption efficiency of the power consumption system is seriously reduced, resulting in a waste of power resources, and at the same time, it h...

Problems solved by technology

Each of the above-mentioned types of power-saving protection sockets has its own functional characteristics, and also has its own limitations. If only one type of power-saving protection socket is used, the best power-saving effect and the impact on electrical equipment cannot be achieved. Effective protection, if multiple types of power-saving protection sockets are used on a power system or power equipment at the same time, the user's investment cost will be increased
