Description
Technical field
The utility model is related to a kind of fuse, more particularly to a kind of preventing arc disconnecting switch formula fuse.
Background technology
The high-tension fuse that circuit, distribution transformer etc. are used both at home and abroad at present adopts zero gram of high pressure；On zero gram of high pressure
Duckbilled is contacted with zero gram tube using spring leaf, and the upper cap of zero gram tube is pinnacle cylinder, so its contact is point contact, contact surface
Product is little, and contact resistance is big.Jing often prevents crane fuse failure or metal cap melting welding from coming off because of heating；Operation certain hour
Afterwards, spring leaf is weak causes crane pipe Automatic-falling, causes unnecessary power outage or phase-deficient operation.Zero gram of lower side base of high pressure
Seat is only tangled the rotating shaft of zero gram tube by hook, and contact area is little, often zero gram of the heating burnout because contact resistance is big.One is used in addition
Individual common screw is fixed, and not only easily causes dislocation in operation so that alternate safe distance is reduced.

Dynamic drawing, closing operation, and do not possess the defencive function of the failures such as short circuit, excessively stream, overload, when breaking down or be abnormal, can only
Using the breaker interrupting short circuit and load current that are installed on circuit head end, Jing is often because a certain user breaks down and causes
Whole piece line tripping is made, causes power failure range to expand, to search trouble point loaded down with trivial details and waste time and energy.Isolation in use at present in addition
The moving contact of disconnecting link can not be taken off by switch, in interruption maintenance, easily cause personnel and close disconnecting link by mistake, cause personnel, equipment thing
Therefore.
The country is installed on disconnecting switch, the high pressure that substation line outlet, high-low pressure power network line, user etc. use at present
Zero gram of fixed form is all to stay one or two screw on a mounting board in advance, due to the screwhole position of cross-arm during in-site installation
Disunity, Jing often cause scene install, and needs carry out changing hole, and are fixed using a screw, and Jing often makes disconnecting link
Install insecure, Jing disconnecting switch positioning often occurs and causes the phenomenons such as too small, the operation inconvenience of alternate safe distance；Both the above sets
Install on standby bar and all screw must be fastened and fixed using upper and lower two spanners, need two people to coordinate and installed, not only prolong
Set-up time and emergency repair time has been grown, man power and material has been also add.
Above disconnecting switch exist without short circuit, excessively stream, overload protection function, without arc-suppression function；Zero gram of high pressure exists easy
Heating burnout, the shortcomings of coming off or weld.And due to, when insecure, installation fee is installed in the restriction of cross-arm width, screw, operating
Laborious deficiency.
The content of the invention
The purpose of this utility model is aiming at the drawbacks described above of prior art presence, there is provided a kind of preventing arc disconnecting switch formula
