Problems solved by technology
[0002] In the power system, the fuse is used for the opening and closing, short circuit and overload protection of the power system. Rain, dust, anti-fouling and anti-corrosion measures, so that it is prone to failure and has a short service life
And the operation is inconvenient, unsafe, and easy to generate arc light
In addition, the opening and closing state of the fuse cannot be determined. When the switch is opened due to a fault or other reason, it needs to be observed on the spot to determine it, which is not convenient for the analysis and treatment of the fault.

The invention discloses an insulation closed type intelligent fuse which comprises a cylindrical insulator. The side wall of the cylindrical insulator is provided with an umbrella skirt, and an installation rack is fixed to the outer wall in the middle of the cylindrical insulator. The insulation closed type intelligent fuse is characterized by further comprising an electric conducting device and an insulating device, wherein the electric connecting device is composed of an upper cable outgoing line, a lower cable outgoing line, an upper fixed contact, a lower fixed contact, an upper moving contact, a lower moving contact and a fuse wire, and the insulating device is composed of an arc extinction pillar, an arc extinction pipe, a load fuse pipe and an arc extinction paper pipe. A load fuse piece is composed of an upper moving contact, a lower moving contact, an arc pulling spring, a fuse wire and a load fuse pipe. The load fuse piece is inserted into the cylindrical insulator, so that the upper moving contact makes contact with the upper fixed contact, the lower moving contact makes contact with the lower fixed contact, and a current loop is formed. A proximity switch connected with an external computer through a wire is arranged at the position where the lower edge of the cylindrical insulator is connected with a cover shell. The insulation closed type intelligent fuse has the advantages of being not prone to generating arcs, high in arc cutting capability, dustproof, rainproof, antifouling, antiseptic, firm, durable and capable of monitoring the on-off states of itself.
Description
technical field [0001] The invention relates to power equipment, in particular to an insulation-enclosed intelligent fuse. Background technique [0002] In the power system, the fuse is used for the opening and closing, short circuit and overload protection of the power system. Rain, dust, anti-fouling and anti-corrosion measures, so that it is prone to failure and has a short service life. Moreover, the operation is inconvenient and unsafe, and it is easy to generate arc light. In addition, the opening and closing state of the fuse cannot be determined. When the switch is opened due to a fault or other reason, it needs to be observed on the spot to determine it, which is not convenient for analyzing and processing the fault. Contents of the invention [0003] The purpose of the present invention is to provide an insulated closed intelligent fuse which is not easy to generate arc, has strong arc cutting ability, is dustproof, rainproof, antifouling, anticorrosion, durabl...
