Description
Technical field
The present invention relates to a kind of small bus break wire pliers, more particularly, to a kind of foot-operated relay protection small bus cutting nipper.
Background technique
Known, totally-enclosed insulation JMX-5 type relay protection small bus terminal runs dangerous, maintenance due to existing
The defects of difficulty is exited in inconvenient, technological transformation, especially gap is smaller between small bus and small bus in power construction, and small bus is adopted
It is the copper rod of diameter 6-8mm, upper layer and lower layer, small bus bar and small bus bar spacing 2cm, interlamellar spacing 4cm generally has
15-40 root, and run for naked dew, it needs to cut small bus in technological transformation, it is other small then to add terminal connection
Bus is achieved technological transformation；Gap is smaller between small bus and small bus when due to needing wiring, and the hand of staff is not to
Middle part between two layers small bus, the terminal among the small bus bar of bottom are unable to wiring, and task difficulty is high, existing method
It is that after small bus is cut among two protection screens with cable clamp, old relay-set could be exited, new screen is in place.
Shear history needs more people to cooperate meticulously, although staff is very conscientious, careful, careful, due to small bus interval gap
Small, exposed electrification, between small bus bar, interlayer it is too small, shear history is time-consuming, laborious, and shearing area is very irregular, it is easy to cause
Small busbar short-circuit；And there are also Danger Electric shock risks by operator；When newly shielding in place, there is the danger for touching small bus.When ordering retainers, servants, etc. to retire out always,
Need to charge the small bus of shearing；After new screen installation, band is also wanted to electrically connect small bus." replacement technology is fallen State Grid Corporation of China's regulation
Afterwards, there are the electrical secondary systems such as the relay protection of significant deficiency, stabilization control device equipment " as the important interior of electric power network technique transformation
One of hold, it is very heavy that power system relay protection device technological transformation upgrades task.
Summary of the invention
In order to overcome the shortcomings in the background art, described to cut the invention discloses a kind of relay protection small bus cutting nipper
Cutting nipper width is more suitble to the small bus of spacing 2cm and small bus operation, has structure simple, effectively overcomes prior art band
The defect of the quick-fried insurance of alternating-current/direct-current miniature bus is cut when electric operation.
In order to realize the goal of the invention, the present invention adopts the following technical scheme:
A kind of relay protection small bus cutting nipper, including lifting rod, square bar, fixed block, hinge, movable block, pressing plate, connecting plate,
Square tube and alloy cutter, one end of square bar are connected in the middle part of the bottom surfaces of lifting rod, are equipped in the other end face side of square bar
The fixed block extended forward, the end face other side of square bar are connected by hinge movable block, and semicircle orifice A, semicircle orifice B are respectively provided at institute
On the corresponding surface for stating fixed block and movable block；One end of connecting plate is connected on one end nozzle of square tube, and the connecting plate other end is set
That sets is punched through the attachment base of side in the middle part of axis connection pressing plate lower face, cuts on the nozzle of the square tube other end equipped with alloy
Knife；The fixed block, movable block and square bar are through in square tube.
The relay protection small bus cutting nipper, the lifting rod, square bar and fixed block setting are integrated.
The relay protection small bus cutting nipper is respectively equipped with two finger arcs in the bottom surfaces square bar two sides of lifting rod
Shape recess.
The relay protection small bus cutting nipper, the connecting plate, square tube and the setting of alloy cutter are integrated.
The relay protection small bus cutting nipper, the connecting plate and the square tube connected on the nozzle of described square tube one end are another
The alloy cutter of setting on the nozzle of one end is the same tube wall both ends of nozzle.
The relay protection small bus cutting nipper is equipped with cambered surface transition on the outside of the other end of connecting plate.
By adopting the above-described technical solution, the invention has the following beneficial effects:
Relay protection small bus cutting nipper of the present invention, the cutting nipper width more be suitble to the small bus of spacing 2cm with it is small
Bus operation, and hand is far from small bus when working, in order to which safety can be on the rear portion of square bar and lifting rod and pressing plate, even
Insulation rubber sleeve is arranged in fishplate bar rear portion, and certain rubber sleeve is common for power department power tool, so the present invention is not written
Right；Another alternative by the rear portion of square bar and lifting rod and pressing plate, connection postlaminar part be set as nylon, can also be real
Existing same technique effect；The configuration of the present invention is simple cuts alternating-current/direct-current miniature bus when effectively overcoming prior art livewire work
The defect of quick-fried insurance.
