Intelligent on-off device of multipurpose power circuit breaker

Abstract

The invention discloses an intelligent on-off device of a multipurpose power circuit breaker and relates to a power supply on-off device. The on-off device comprises a power supply end (50), a universal switch (40) and a power consuming end (60) which are connected from the front to the end in turn, and is provided with an electrical parameter detection circuit (10), an operation processing circuit (20) and a mechanical transducer (30) which are connected from the front to the end in turn, wherein the electrical parameter detection circuit (10) is connected with the power supply end (50); and the mechanical transducer (30) is connected with the universal switch (40). The intelligent on-off device of the multipurpose power circuit breaker has the advantages of functions of quick response and full protection, capability of solving the problem of one-mode multifunction, small occupied space of the structure, convenient installation and maintenance, no need of connecting cables for modules, and capability of improving the reliability and the protection effect and wide application, wherein the device is not only suitable for various communication base stations but also can be widely applied to the automatic protection and the safety protection of multiple kinds of unmanned foundation equipment such as railway, petroleum, electric power, broadcasting television and the like..

Description

technical field [0001] The invention relates to a power switching device, in particular to an intelligent switching device for a multipurpose power circuit breaker. Background technique [0002] Communication base stations are the most basic equipment in the communication industry. my country's major operators have millions of base stations across the country; and with the continuous expansion of 3G mobile services in recent years, the three major operators currently have hundreds of thousands of 3G base stations across the country. Communication base stations often cause a lot of maintenance costs due to power supply quality and lightning natural disasters every year, making the maintenance cost of base stations the largest consumption cost in the communication industry, accounting for 41% of the entire communication operating cost. [0003] Power supply interruption, overvoltage and undervoltage are the basic reasons for equipment malfunction, and overcurrent is the basic ...

AI Technical Summary

Problems solved by technology

There is no protection function for overvoltage and undervoltage, and it is not sensitive to overcurrent protection actions, whether it is action time or tripping current, especially the protection parameters cannot be accurately set according to the purpose (user); the protection effect on damage to various electronic equipment poor

[0005] At present, there is still a kind of opening and closing device that is used in a small amount. The opening and closing device uses the working current of the relay to open and close the equipment. It cannot meet the "breaking capacity" of the relevant standards, the breaking current is small, and the reliability and safety are poor; Combination of discrete components, large volume
