An electronic type low-pressure distribution transformer fuse case provided with an inverse-time characteristic belongs to the field of emergent protection devices, and comprises a circuit overload protection module arranged in a case body, wherein the circuit overload protection module comprises a mutual inductor group, circuit breaker switches and a control unit; the mutual inductor group is connected in series with a three-phase major loop, is used for measuring the load current values of various phases of the major loop in a real-time manner and sending the measured result to the control unit; the circuit breaker switches are used for switching on/off a three-phase circuit of the major loop under the control of the control unit; the control unit compares the absolute values of the load current values of the various phases of the major loop or the variation trend of the load current of the various phases with an inverse-time characteristic curve, performs the 'trip' operation control for the circuit breaker switches, and remotely transmits the circuit load current and the states of the circuit breaker switches to a host computer in a digital signal form. According to the invention, the fuse case realizes the intelligent upgrade of products, meets the operation requirements of an intelligent power grid, and can be widely applied to the field of the intelligent control of a low-pressure power transformation and distribution system.
