Background technology
Current-limiting fuse is referred to cut off in rated current and current-limiting zone at which and safely cuts off all being likely to occur
Electric current fuse, be very common protection device in power system, as which can be more quickly cut off than breaker
Circuit, therefore be widely used for protecting the equipment such as generator, transformer very much in power system.High-voltage and current-limitation fuse is generally
Column type, outside are usually ceramic package, and middle is ceramic seven-star spinous process of the seventh cervical vertebra frame, and it is in spiral shell that the melt of fuse is usually several parallel connections
Rotation shape is looped around on skeleton.As current-limiting fuse can produce high temperature in running, so needing using pedestal to protect, base
The use of seat can not only effective protection fuse intraware, also act as supports, the effect of fixation fuse intraware.
But, the existing pedestal for supporting current-limiting fuse yet suffers from weak point when in use, due to limit
Streaming fuse produces high temperature, so easily causing the pedestal of fuse to be heated, is inconjunction with pedestal in running inside device
It is heated for fixed nut, the easily expansion because nut is heated is fixedly installed to inside specific small space again, so
Nut expanded by heating can then extrude pedestal, if the pedestal of plastic material deforms then can pedestal, base of ceramic may press into broken
Split, the stability that strong influence pedestal is used.Therefore, a kind of base for supporting current-limiting fuse is proposed for the problems referred to above
Seat.
The content of the invention
The purpose of the present invention is that to solve the above problems and provides a kind of pedestal for supporting current-limiting fuse.
The present invention is achieved through the following technical solutions above-mentioned purpose, a kind of pedestal of support current-limiting fuse, including
First connection contact, the first connection contact side arrange second and connect contact, and the first connection contact and described the
Two connection contacts is installed on pedestal, it is described state the first connection contact be connected with described second contact both sides be all connected with fixation
Plate, connects earthenware, and the ceramic tube inside installs the first screw, first screw and the pottery below the fixed plate
Moisture absorption plate is installed in the junction of porcelain tube, and the second nut is installed in the second connection contact side.
Preferably, in order that the pedestal has more good heat dispersion, radiating is provided with the base outer wall outer
Shell.
Preferably, in order that the wire of the base interior is stably fixed to inside device, not with remaining component phase
Contact, effectively prevents wire heat damage, and the first connection contact is connected inside contact with described second and is respectively provided with trough.
Preferably, in order that the pedestal overall structure is more stable, the fixed plate side arranges draw-in groove, and the card
Connected nail is installed inside groove, the fixed plate is fixedly connected the pedestal by connected nail.
Preferably, in order that the water energy of moisture absorption plate absorption enough penetrates into the ceramic tube inside, and with the earthenware
Internal ammonium nitrate reaction, produces the effect of heat absorption, it is to avoid first nut, the second nut expanded by heating, the suction
Damp intralamellar part is provided with water seepage hole, and the ceramic tube inside is filled with ammonium nitrate.
Preferably, in order that the pedestal is more stable when intraware is supported, the pedestal overall structure is U-shaped knot
Structure.
The invention has the beneficial effects as follows：As current-limiting fuse is in running, high temperature is produced inside device, so easily
Cause the pedestal of fuse to be heated, be inconjunction with pedestal and be heated for fixed nut, the easily expansion because nut is heated, and quilt
It is fixedly mounted on inside specific small space, so nut expanded by heating can then extrude pedestal, if the pedestal of plastic material
Pedestal can then deformed, base of ceramic may press into fragmentation.By in the earthenware that the base interior of the present invention installs nut
Ammonium nitrate is filled in portion, and installs moisture absorption plate in the junction of nut and earthenware, using the moisture in moisture absorption plate absorption air,
And ceramic tube inside is penetrated into, ammonium nitrate is met water heat absorption, so as to reduce ceramic tube inside temperature, effectively prevents ceramic tube inside nut
Thermal expansion extruding causes earthenware to deform, so as to increase stability when pedestal is used, and security.By the base in device
Heat-dissipating casing is set on seat, the heat sinking function of device is effectively increased, it is ensured that base interior component being capable of stable operation.And device
Generally ceramic material, with good high-temperature stability, and service life is longer.
