The utility model has the following advantages that:
Compared with prior art, present patent application has the technical effect that:
1. it is windproof, anti-pollution.Because using interpolation type structure, do not fall off to the wind not only, and also add conductor contact surface,
Solve the problems, such as the arc short-circuit caused during switching on operation:Top seal, can be greatly lowered environmental pollution, and sand and dust
With the erosion of sleet.
2. anti-fault-free comes off.Using the fuse of new structure, it is to avoid as dust storm, vibrations, overload, weather become
The influence of the natural environment such as change, hot and cold.
3. closing success rate is high.Because the fuse of new structure has with the different part of old-fashioned fuse:1. novel spraying
The fuse for penetrating formula fuse is not subject to pulling force;2. do not limited by fusion tube length;3. fast, success rate of closing a floodgate is high, conductive contact surfaces
Greatly.First, the fuse of old-fashioned fuse will because of the pulling force by more than 50N, be easy in closing operation moment disconnect, it is necessary to
The fuse renewed again is taken off, causes upper and lower contact distance to change because changing during fuse, combined floodgate will be made
It is difficult;Secondly, when more renewing fusion tube, because of corresponding problem, adjustment is difficult, after equipment adjustment, and flexibility ratio and fitness have can
Original state can not reached, cause closing success rate than relatively low, the conduction contact part of old-fashioned fuse is generally that line and small area connect
Touch, operational reliability is poor.
4. circuit operational efficiency is high.
5. by melt itself fusing, forming electric arc, then under high arc temperature effect, the gas exhausted material in arc cylinder will be cut
After gasification, a large amount of gases are produced, by arc blow out.
6. solving existing fuse does not have the defect of visual fracture.By fracture detector, fuse can be detected
Inside is combined floodgate or gate-dividing state, while providing signals to subordinate's processing.
