Abstract

The invention belongs to the field of power system detection, in particular to a protection device for a high-voltage line fuse and a transmission and distribution detection system. The protection device comprises a current temperature sampling module, a microprocessor and a knife switch tripping module, wherein the current temperature sampling module is used for sampling and shaping a current temperature signal of a high-voltage line by an electromagnetic induction principle and outputting the shaped current temperature signal; the microprocessor is used for performing digital analysis, processing and judgment on a current signal processed by the current temperature sampling module in the high-voltage line, and outputting a control signal; and the knife switch tripping module is used for controlling the on and off states of a knife switch according to the control signal of the microprocessor. The protection device effectively prevents the maloperation and the slow motion of the preposed knife switch tripping module by adopting the structures such as the microprocessor, the knife switch tripping module and the like, so that a circuit is cut off before meeting a fusing current and a time condition of the fuse to avoid unnecessary fusing of the fuse; therefore, risk probability of major accidents of the high-voltage line is reduced; national metal resources are also effectively saved; and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the field of power system detection, and in particular relates to a protection device for a high-voltage line fuse and a power transmission and distribution detection system. Background technique [0002] At present, as an overload protection measure, the fuse has the characteristics of simple implementation, good protection effect, low cost, low requirements on the technical level of operators, and easy popularization. It has played an indelible role in the process of social development, especially in the process of using electric energy. role and credit. However, as a one-time measure, the fuse is used as a one-time measure. In today's increasingly tense social resources, the prices of various metal materials are getting higher and higher. , In this way, the production cost and material consumption of the society will be increased virtually. At the same time, the high temperature at the moment of fuse breaking also vaporize...
