Abstract

The invention discloses a multifunctional terminal electric appliance, which comprises a breaker and an intelligent control device, wherein the breaker comprises a hand shank and a first tripping drive mechanism; when a short-circuit current appears in the breaker, an electromagnetic release of the first tripping drive mechanism drives the breaker to achieve opening; the intelligent control device comprises a control assembly, a display screen and a second tripping drive mechanism; the control assembly drives the second tripping drive mechanism to move to trigger the release, so that the breaker is opened to achieve protection for an overvoltage, an overcurrent, an undervoltage and the like of the breaker when a current exceeds a set value or a voltage value exceeds the set value or is lower than the set value; and the control assembly calculates the power consumption according to the obtained current value and voltage value, and displays the calculated power consumption on a display screen in real time. Therefore, the multifunctional terminal electric appliance disclosed by the invention provides overvoltage, overcurrent, undervoltage and short-circuit protections for a circuit, and also has the function of an ammeter.

Description

technical field [0001] The invention discloses a multifunctional terminal electric appliance, which belongs to the field of low-voltage electric appliances. Background technique [0002] In the power distribution system in the field of low-voltage electrical appliances, multi-functional terminal appliances (CPS for short, also known as control and protection switching appliances) are the best substitute products for low-voltage electrical appliances such as circuit breakers, contactors, thermal relays, and fuses, which can reduce the number of lines The types, specifications, quantities, line faults and energy consumption of the components required in the system solve the problem of coordination between various electrical appliances. In short, the multi-functional terminal appliances in the power distribution system can simplify the circuit wiring scheme, realize the intelligent control of the power system, and save power. With the continuous development of technology in th...
