Description
Technical field
The present invention relates to a kind of small busbar break wire pliers, more particularly, to a kind of foot-operated relay protection small bus cutting nipper.
Background technology
Known, totally-enclosed insulation JMX-5 type relay protection small bus terminals run dangerous, maintenance due to existing
The defects of difficulty is exited in inconvenient, technological transformation, especially gap is smaller between small busbar and small busbar in power construction, and small busbar is adopted
It is the copper rod of diameter 6-8mm, upper and lower two layers, small bus bar and small bus bar spacing 2cm, interlamellar spacing 4cm, generally has
15-40 roots, and run for naked dew, need to cut small busbar in technological transformation, it is other small then to add terminal connection
Busbar, is achieved technological transformation；Gap is smaller between small busbar and small busbar during due to needing wiring, and the hand of staff is not to
Middle part between two layers small busbar, 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 busbar 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 coordinate meticulously, although staff is very conscientious, careful, careful, due to small busbar interval gap
It is small, exposed powered, 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 causes
Small busbar short-circuit；And operating personnel also have Danger Electric shock risk；When newly shielding in place, there is the danger for touching small busbar.When ordering retainers, servants, etc. to retire out always,
Need the powered small busbar of shearing；After new screen installation, band is also wanted to electrically connect small busbar." replacement technology falls State Grid Corporation of China's regulation
Afterwards, the electrical secondary system such as the relay protection there are significant deficiency, stabilization control device equipment " is transformed important interior as electric power network technique
One of hold, power system relay protection device technological transformation upgrading task is very heavy.
The content of the invention
It is described to cut the invention discloses a kind of relay protection small bus cutting nipper in order to overcome the shortcomings of in background technology
Cutting nipper width is more adapted to the small busbares of spacing 2cm and small busbar operation, has simple in structure, effectively overcomes prior art band
The defects of alternating-current/direct-current miniature bus quick-fried insurance is cut during electric operation.
In order to realize the goal of the invention, the present invention adopts the following technical scheme that：
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 with the other end face side of square bar
The fixed block extended forward, the end face opposite side of square bar are respectively provided at institute by hinge connection movable block, semicircle orifice A, semicircle orifice B
On the corresponding surface for stating fixed block and movable block；One end of connecting plate is connected on one end mouth of pipe of square tube, and the connecting plate other end is set
That puts is punched through the connecting seat of side in the middle part of axis connection pressing plate lower face, is cut on the mouth of pipe 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 set and are integrated.
The relay protection small bus cutting nipper, two finger arcs are respectively equipped with the bottom surfaces square bar both sides of lifting rod
Shape is recessed.
The relay protection small bus cutting nipper, the connecting plate, square tube and alloy cutter set and are integrated.
The relay protection small bus cutting nipper, the connecting plate and the square tube connected on the mouth of pipe of described square tube one end are another
The alloy cutter of setting on the mouth of pipe of one end is the same tube wall both ends of the mouth of pipe.
The relay protection small bus cutting nipper, it is excessive to be equipped with cambered surface on the outside of the other end of connecting plate.
By adopting the above-described technical solution, the present invention has the advantages that：
Relay protection small bus cutting nipper of the present invention, the cutting nipper width more be adapted to the small busbares of spacing 2cm with it is small
Busbar operation, and hand is away from small busbar when working, in order to which safety can be on the rear portion of square bar and lifting rod and pressing plate, even
Fishplate bar rear portion sets insulation rubber sleeve, and certain rubber sleeve is commonly used for power department power tool, so the present invention does not write
Right；Another substitute mode by the rear portion of square bar and lifting rod and pressing plate, connection postlaminar part be arranged to nylon, also can be real
Existing constructed effect；The configuration of the present invention is simple, alternating-current/direct-current miniature bus is cut when effectively overcoming prior art livewire work
The defects of quick-fried insurance.

Embodiment
Explanation that can be detailed by the following examples is of the invention, and the open purpose of the present invention is intended to protect model of the present invention
All interior technological improvements are enclosed,
Relay protection small bus cutting nipper with reference to described in attached drawing 1~4, including lifting rod 1, square bar 3, fixed block 7, hinge 4, work
Motion block 5, pressing plate 9, connecting plate 13, square tube 14 and alloy cutter 15, one end of square bar 3 are connected in the middle part of the bottom surfaces of lifting rod 1,
Two finger arc-shaped recess 2 are respectively equipped with 3 both sides of bottom surfaces square bar of lifting rod 1, are set in the other end face side of square bar 3
There is the fixed block 7 extended forward, the end face opposite side of square bar 3 connects movable block 5, B8 points of semicircle orifice A6, semicircle orifice by hinge 4
It is not located on the corresponding surface of the fixed block 7 and movable block 5；One end of connecting plate 13 is connected on one end mouth of pipe of square tube 14,
The perforation 12 that cambered surface 18 is excessive, and 13 other end of connecting plate is set is equipped with the outside of the other end of connecting plate 13 by axis 11 to connect
The connecting seat 10 of 9 lower face of pressing plate, 17 middle part side is connect, alloy cutter 15 is equipped with the mouth of pipe of 14 other end of square tube；It is described solid
Determine block 7, movable block 5 and square bar 3 to be through in square tube 14.
Further, the connecting plate 13 connected on 14 one end mouth of pipe of square tube and setting on 14 other end mouth of pipe of square tube
The alloy cutter 15 put is the same tube wall both ends of the mouth of pipe.
Implement relay protection small bus cutting nipper of the present invention, the movable block 5 of 3 lower end of square bar is closed with fixed block 7
And the square tube 14 of 13 lower end of connecting plate is then passed through, pressing plate 9 is turned down using connecting seat 10 so that pressing plate 9, the lower face
17 correspond to the upper surface of lifting rods 1, and when use is blocked respectively using the semicircle orifice A6 of fixed block 7 and the semicircle orifice B8 of movable block 5
The two sides of small busbar 16, push the pressing plate 9, four fingers above carry lifting rod 1, and " at this moment the square tube 14 ensures movable block by the centre of the palm
5 do not separate with fixed block 7 ", the alloy cutter 15 will clamp small busbar 16 disconnected, be protected be subject to semicircle orifice A6 and semicircle orifice B8
Shield, clamps the disconnected more specification of small busbar 16, section is neat, beneficial to mounting terminal.
Part not in the detailed description of the invention is the prior art.
