Abstract
The invention discloses a fuse emergency auxiliary contact, which simplifies steps of processing a faulty fuse wire, greatly reduces the night work time and work intensity of a worker, improves the working safety to the greatest degree, greatly reduces the potential safety hazard during work, improves the speed of recovering the power supply to a great degree, and saves precious time for further repairing and analyzing accident causes. The fuse emergency auxiliary contact is realized by the following technical scheme: the fuse emergency auxiliary contact comprises two contact blades which are vertically fixed on two sides of a base respectively, and the sections of the contact blades are in an inverted U shape.
Description
Technical field
The present invention relates to a kind of auxiliary contact, relate in particular to a kind of fuse emergency auxiliary contact.
Technical background
PRW10 series fuse switch is the most frequently used a kind of protective switch of the short circuit of 10kV distribution line branch line and distribution transformer; it have economy, easy to operate, adapt to characteristics such as outdoor environment is strong, be widely used in 10kV distribution line and distribution transformer primary side as protection with carry out the usefulness that equipment is thrown, cut operation.Fuse switch when having overload and short circuit current to pass through, can cut-off circuit as overcurrent protective device timely, plays the effect of protection equipment and circuit.But owing to install or misoperation, product quality, reasons such as environmental factor usually can make contact produce temperatures involved to the fuse operate as normal.Especially fuse is assigned a new job, accounted for very big ratio in the repairing work at night, yet carry out charged transposing fuse at night, because the night lights illumination is not enough, operating difficulties, loaded down with trivial details, the transposing fuse operating procedure complexity of fault fuse repairing flow process, workload is big, the emergency first-aid repair method is single, lack a series of problems such as effective treating method, often cause staff's psychological stress, stress is big, increase the danger of operation, user's power supply reliability also can't ensure.
Summary of the invention
The present invention has overcome deficiency of the prior art, a kind of fuse emergency auxiliary contact is provided, realized simplifying the step of handling failure fuse, staff's night work time and operation intensity have been significantly reduced, improved operational security to the full extent, greatly reduce the potential safety hazard in the work, improved the speed that restores electricity to a great extent, simultaneously for further maintenance and analysis accident cause have won valuable time.
The present invention is achieved by following technical proposals:
A kind of fuse emergency auxiliary contact comprises two contacts that are vertically fixed on the base both sides respectively, it is characterized in that, described contact cross section vertically is " several " word shape.
Described a kind of termination that is used for the instrument of cutting off wound foreign matter, wherein there is a fusing carrier connecting hole that vertically runs through at the base center, and there is a screw at the middle part of the side end face on base base.
Described a kind of termination that is used for the instrument of cutting off wound foreign matter, wherein the base both sides are fixed in by nut in the contact bottom, and two contact tops are respectively the rectangle lengthy motion picture that stretches out and be bent into certain angle.
Described a kind of termination that is used for the instrument of cutting off wound foreign matter, wherein the part of " several " word shape of contact is outwards protruded.
Owing to adopt technique scheme, a kind of fuse emergency auxiliary contact provided by the invention has such beneficial effect: the step that has realized simplifying the handling failure fuse, staff's night work time and operation intensity have been significantly reduced, improved operational security to the full extent, greatly reduce the potential safety hazard in the work, improved the speed that restores electricity to a great extent, simultaneously for further maintenance and analysis accident cause have won valuable time.
Description of drawings
Fig. 1 is the structural representation of a kind of fuse emergency auxiliary contact of the present invention.
Embodiment
Below by embodiment the present invention is described in further detail.
See also Fig. 1, there is shown a kind of fuse emergency auxiliary contact of the present invention, comprise two contacts 1 that are vertically fixed on base 2 both sides respectively, contact 1 cross section vertically is " several " word shape, the part of " several " word shape is outwards protruded, base 2 both sides are fixed in by nut 4 in contact 1 bottom, and two contacts, 1 top is respectively the rectangle lengthy motion picture that stretches out and be bent into certain angle.There is a fusing carrier connecting hole 3 that vertically runs through at base 2 centers, and there is a screw 5 at the middle part of the side end face on base 2 bases.
During practical set, by screw 5 the last cap end of base 2 and fusing carrier is cooperated with bolt, making base 2 and fusion tube is same central shaft.Left and right sides contact 1 certain angle that tilts laterally respectively can easily use link rod that fusing carrier is hung in the fuse when operation.
Separate at " several " word shape projection of contact 1 and the position of burning of upper bracket, is keeping having stablized contact resistance under the original effectiveness of auxiliary contact, makes that burning the position can further not spread.
For the operating personnel who rushes to repair fuse night, with a simple operations of installing emergency auxiliary contact additional, replaced complicated transposing fuse work, not only reduced activity duration and intensity, more increased the fail safe of live line working simultaneously.
Do not calculating under the situation of convening repairing personnel, range of driving equal time factor, normal charged transposing fuse and the time that restores electricity were generally 30-35 minute, but after having used emergency auxiliary contact, time just descends greatly, promptly can be the user who has a power failure because of the fuse fault at 4-5 minute substantially and restores electricity through testing.
Used after the emergency auxiliary contact, reduced operating personnel's the time and intensity of working at night, improved operational security to the full extent, greatly reduced the potential safety hazard in the work.
Fuse repairing scene installs emergency auxiliary contact additional, can solve the fuse fault of very big certain customers, has not only improved the speed that restores electricity to a great extent.Simultaneously for further maintenance and analysis accident cause have won valuable time.
The handling safety of PRW type fuse emergency auxiliary contact, of many uses, and it no longer need handle the fuse fault to change whole fuse, and shirtsleeve operation no longer is subjected to complicated live line working condition restriction, only needs take off expulsion tube with link rod, add on ground and to install auxiliary contact, using the same method hangs up again, and recovers to send electricity, this singly do not alleviate the repairing at night of charged class operating pressure, improved fail safe, simplify the workflow of emergency first-aid repair more, improved power supply reliability.
Above execution mode has been described in detail the present invention, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details in the execution mode should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
