Abstract

The invention discloses a solid fuse, which comprises a fuse cavity, a first inner conical plug and a second conical plug, wherein the first inner conical plug is connected with the fuse cavity and the second inner conical plug, and the first inner conical plug is used for sealing the fuse cavity. In addition, the fuse cavity is connected with the fuse, and the second inner conical plug is connected with an outgoing cable. According to the solid fuse provided by the invention, problems in the prior art that the surface of the fuse is enabled to have dirt, oxidation and the like due to long-time exposure of the fuse in a circuit and that the safety of the circuit is affected can be avoided, and dual purposes of full sealing and short-circuit protection for the fuse are achieved.

Description

technical field [0001] This application relates to the field of electrical technology, in particular to a solid fuse. Background technique [0002] With the rapid development of society, the proportion of electrification in daily life is also increasing. In order to meet the reliability of power supply in daily life and work, the role played by substations in providing stable power supply cannot be underestimated. [0003] Among them, the substation is the place where the voltage is changed. The function of the substation is to transmit the electric energy from the power plant to a distant place, first increase the voltage to high-voltage electricity, and then reduce the voltage as needed near the user for use by the user. In the substation, equipment such as high-voltage switchgear needs to provide operating power, but because there is no low-voltage power supply for the time being when operating the high-voltage cabinet, the staff installs a transformer with a small capac...
