Abstract

Provided is an intelligent hand cart breaker. The intelligent hand cart breaker comprises a chassis cart, a frame arranged on the chassis cart, a transmission mechanism arranged on the frame, an intelligent monitoring unit internally-arranged portion, an electronic transformer, a permanent magnetic mechanism and a permanent magnetic mechanism driver. The frame is further provided with a digital line protective device, and the digital line protective device is connected with the intelligent monitoring unit internally-arranged portion and the electronic transformer respectively. The intelligent hand cart breaker provided with the internally-arranged digital line protective device has the advantages that compared with the prior art, the intelligent hand cart breaker is more intelligent, space in a switch cabinet is saved and the switch cabinet can be developed towards the miniaturization trend because the digital line protective device in the switch cabinet of a power distribution system is arranged in the intelligent hand cart breaker; the digital line protective device is simple in structure, small in size, convenient to install and firm in fixing because the digital line protective device is connected with the frame through a fixing frame.

Description

technical field [0001] The invention relates to an intelligent handcart circuit breaker, in particular to an intelligent handcart circuit breaker with a built-in digital line protection device. The invention also relates to an intelligent switch cabinet installed with the above-mentioned intelligent handcart circuit breaker. Background technique [0002] When the power system is in operation, due to natural factors (lightning strikes, condensation), equipment manufacturing defects, design and installation errors, unqualified inspection quality or improper operation and maintenance, short circuits or abnormal operating conditions may occur in the power system. cause accidents. Once a fault occurs, the faulty component must be removed quickly and selectively. Digital line protection device refers to the ability to respond to the failure or abnormal operation of electrical components in the power system, and automatically, quickly and selectively act on the circuit breaker or ...
