Abstract
The utility model relates to a quick fuse for a low-voltage apparatus used in the hospital, which is composed of a current conducting plate, a cooling water channel, a water pipe connecting pipe, an insulating tube, fusion splices, quartz sand and transition plates. The transition plates are arranged on the inner lateral surface of the current conducting plate made of copper, and the fusion splices made of silver are arranged between the transition plates in a welding form. The quartz sand is respectively filled between the fusion splices and between the transition plates, and the insulating tube for protection is arranged on the outer end surface filled with the quartz sand. The current conducting plate adopts a hollow structure, namely, the cooling water channel is arranged in the current conducting plate, and the water pipe connecting pipe communicated with the cooling water channel is arranged at one end of the current conducting plate. The quick fuse has the advantages that the integral structure is simple, the volume of the device is small, and the cooling effect is good by adopting the form of forced cooling with water, therefore, the effect of the quick fuse is good, the electric technical performance of the fuse is enhanced, simultaneously, the power consumption of the fuse is also reduced, the efficiency is improved, and the reliability for being used in the hospital is especially ensured.
Description
Technical field:
The utility model relates to low-voltage electrical apparatus control and uses servicing unit, relates in particular to hospital's low-voltage electrical apparatus fast acting fuse.
Background technology:
All kinds of low-voltage electrical apparatuses that hospital uses, the of paramount importance reliability that is work.The fast acting fuse of prior art substantially all is made up of fuse piece, rebound, insulated tube and contact tube, and fuse piece is welded on the rebound, is filled with quartz sand between fuse piece, and the overcoat insulated tube is protected.Rebound then is welded on the conductive plate of copper or alloy aluminum matter, adorns indicating device outward.The heat radiation of this fuse is maximum difficulty, causes the volume of this device big, and the electrical connection power consumption is big, poor electrical performance.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of hospital low-voltage electrical apparatus fast acting fuse is provided, and overall structure is simple, and volume is little, and is low in energy consumption, good heat dissipation effect, stable work in work.
Hospital described in the utility model low-voltage electrical apparatus fast acting fuse includes conductive plate, cooling-water duct, water pipe tube connector, insulated tube, fuse piece, quartz sand and rebound and forms.The conductive plate that peripheral hardware is copper, the conductive plate medial surface is provided with rebound, and the form with welding between the rebound is provided with silver fuse piece.Between each fuse piece, also be between rebound, be filled with quartz sand, be filled with on the outer face of quartz sand, be provided with the insulated tube of protection usefulness.The structure of sky just was provided with cooling-water duct in said conductive plate was arranged in conductive plate, at an end of conductive plate, was provided with the water pipe tube connector that is connected with cooling-water duct, made conductive plate become the but heat abstractor of form of Forced water cooling.
Hospital described in the utility model low-voltage electrical apparatus fast acting fuse, overall structure is simple, device volume is little, because the form that has adopted water flowing to force cooling, good cooling results is so quick fuse is effective, improved the electrical technology performance of fuse, also reduce simultaneously the power consumption of fuse, improved efficient, especially guaranteed the reliability that hospital uses.
