A high-voltage and high-current fast fuse comprises an end cover, a contact, a fuse tube, a fuse body, a fuse body guide column, arc extinguishing filler and a fastening screw, characterized in that two or more fuse body guide columns are arranged in the fuse tube, the fuse body is fixed on the fuse body guide column in a spiral winding manner, the contact is provided with a fuse body perforation, the fuse body is welded on the outer end surface of the contact through the perforation, the end cover end surface is overlapped on the outer end of the contact and is connected and fixed with the contact through the fastening screw installed hole of the end cover and the contact and the fastening screw. The disadvantages of poor welding are overcome to the maximum extent. In the case of not increasing the length of the fuse tube or even shortening the length, the rated voltage and the rated current of the fuse can be effectively improved, the anti-impact and anti-bumping capabilities of the fuse are improved, and the fuse can be used to protect the integrated power system of a ship, a large energy storage and power transmission system and other high-voltage and high-current power transmission systems.

A kind of heat dissipation structure for LED light strip, including mounting bracket and at least one heat dissipation part on mounting bracket, characterized in that, the heat dissipation part is attached with LED light strip by mounting bracket, the two sides of mounting bracket have mounting slot, for heat dissipation part to limit, the opening of mounting slot is through, the outside of heat dissipation part in mounting slot has plug-in unit, the outside of plug-in unit is provided with extension plate, the fin on the extension plate is used to conduct heat absorbed by heat dissipation part outward;Mounting bracket is made of soft material as a whole, can be well fitted on bendable light band, and the cooperation mode of mounting bracket bottom surface slot and heat dissipation part makes it possible to achieve better heat conduction and heat dissipation function at each part of light band bending, solves the problem that conventional metal heat dissipation fin cannot bend with light band, leading to part of light band cannot be covered by heat dissipation.

This invention discloses a safety monitoring device for university laboratories, belonging to the field of monitoring equipment technology. The invention includes a top frame, monitoring components, an electrical control box, a fire extinguishing component, and a heat dissipation component. Multiple monitoring components are arranged at the bottom of the top frame. The top frame rotates via a rotating mechanism and rises and falls via a lifting mechanism. Each monitoring component includes a mounting plate with a camera body fixed through its center. A support lug is provided at the top of the mounting plate. A crossbeam is integrally formed in the middle of the top frame. This invention enhances the security of the safety monitoring device by incorporating a fingerprint recognition module, a speaker, and various sensors. The fire extinguishing component provides fire-fighting capabilities, and the heat dissipation component improves heat dissipation, thus solving the problems of limited functionality and insufficient security in existing safety monitoring devices.

The present invention relates to a passive condensation tank cooling system of a passive auxiliary feedwater system and, more specifically, to a passive condensation tank cooling system of a passive auxiliary feedwater system, the cooling system having a passive condensation tank that includes an inner wall and an outer wall, having a cooling means interposed between the inner wall and the outer wall so that the temperature of heat-exchange water can be prevented from rising during condensation in the passive condensation tank, and thus the cooling performance of the passive auxiliary feedwater system can be improved, and being capable of contributing to the ensuring of a long-term cooling function during an extreme disaster accident. To this end, provided is the passive condensation tank cooling system of a passive auxiliary feedwater system, the cooling system comprising: the passive condensation tank having a water storage space in which the heat-exchange water is stored; and the passive auxiliary feedwater system including a condenser submerged in the heat-exchange water of the passive condensation tank, wherein the passive condensation tank includes: the outer wall for forming the outermost wall of the passive condensation tank; and the inner wall spaced from the outer wall to form the water storage space, and the cooling means capable of absorbing heat of the heat-exchange water is interposed between the outer wall and the inner wall.
