Technical Field
The invention relates to a small bus cutting pliers, in particular to a pedal relay protection small bus cutting pliers.
Background
The fully-closed insulated JMX-5 type relay protection small bus terminal has the defects of unsafe operation, inconvenient maintenance, difficult withdrawal of technical improvement and the like, particularly the gap between a small bus and a small bus in power construction is small, the small bus adopts a copper rod with the diameter of 6-8mm, the small bus is divided into an upper layer and a lower layer, the distance between a small bus bar and the small bus bar is 2cm, the distance between layers is 4cm, 15-40 bus bars are generally arranged, the small bus bar is operated in a fully-exposed state, the small bus bar needs to be cut off when the technology is improved, and then a terminal is added to be connected with other small buses, so that the technical improvement is realized; because the clearance between the small buses is small when the wiring is needed, a worker can not reach the middle part between the two layers of the small buses, the terminal in the middle of the bottom layer of the small bus bar can not be connected, the operation difficulty is extremely high, the existing method is that the old relay protection screen can be withdrawn and the new screen is in place after the small buses are cut off between the two protection screens by using cable calipers. The shearing process needs to be carefully matched by a plurality of people, and although workers are very serious, cautious and careful, the small bus bars and the small bus bar layers are too small due to small gaps and exposed electrification among the small bus bar intervals and between the small bus bars, the shearing process is time-consuming and labor-consuming, the shearing section is not neat, and the short circuit of the small bus bars is easily caused; and the operators are also in danger of electric shock; when the new screen is in place, there is a danger of touching the small bus. When the old screen exits, the small bus needs to be cut in an electrified way; and after the new screen is installed, the small bus needs to be electrified. The national grid company stipulates that 'secondary system equipment such as relay protection and stable control devices with backward replacement technology and major defects' is one of important contents for power grid technology transformation, and the technical transformation and upgrading tasks of the relay protection devices of the power systems are very heavy.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention discloses a relay protection small bus shearing pliers, the width of the shearing pliers is more suitable for the operation of small buses and small buses with the distance of 2cm, the structure is simple, and the defect that the safety of an alternating current/direct current small bus explosion is cut in the live-line operation in the prior art is effectively overcome.
In order to realize the purpose, the invention adopts the following technical scheme:
a relay protection miniature bus shearing pliers comprises a lifting rod, a square rod, a fixed block, a hinge, a movable block, a pressing plate, a connecting plate, a square tube and an alloy cutter, wherein one end of the square rod is connected to the middle of the lower surface of the lifting rod, the fixed block extending forwards is arranged on one side of the end surface of the other end of the square rod, the other side of the end surface of the square rod is connected with the movable block through the hinge, and a semicircular hole A and a semicircular hole B are respectively formed in the corresponding surfaces of the fixed block and the movable block; one end of the connecting plate is connected to a pipe orifice at one end of the square pipe, a through hole arranged at the other end of the connecting plate is connected with a connecting seat at one side of the middle part of the lower plate surface of the pressing plate through a shaft, and an alloy cutter is arranged on the pipe orifice at the other end of the square pipe; the fixed block, the movable block and the square rod are arranged in the square tube in a penetrating mode.
The relay protection small bus shearing pliers are characterized in that the lifting rod, the square rod and the fixing block are integrated.
The relay protection small bus shearing pliers are characterized in that two finger arc-shaped depressions are respectively formed in two sides of a square rod on the lower surface of a lifting rod.
The relay protection miniature bus shearing pliers are characterized in that the connecting plate, the square tube and the alloy cutter are integrated.
The relay protection miniature bus shearing pliers are characterized in that the connecting plate connected to the pipe orifice at one end of the square pipe and the alloy cutter arranged on the pipe orifice at the other end of the square pipe are both ends of the same pipe wall of the pipe orifice.
The relay protection small bus shearing pliers are characterized in that an arc surface transition is arranged on the outer side of the other end of the connecting plate.
Due to the adoption of the technical scheme, the invention has the following beneficial effects:
according to the relay protection small bus shearing pliers, the width of the shearing pliers is more suitable for the operation of small buses and small buses with the distance of 2cm, the hand is far away from the small buses during working, insulating rubber sleeves can be arranged on the rear parts of square rods, the lifting rods, the pressing plates and the connecting plates for safety, and the rubber sleeves are common tools for the operation of the power department, so that the invention is not written with right; in another alternative mode, the rear parts of the square rods, the lifting rods, the pressure plates and the connecting plates are made of nylon, and the same technical effect can be achieved; the invention has simple structure and effectively overcomes the defect of shearing off the AC/DC small bus explosion insurance in the live-line work of the prior art.
