Abstract
The utility model discloses a kind of 35kV-PT built-in type high pressure fuse replacement aid, it solve that existing built-in type high pressure fuse replacement maintainer is many, difficulty is large, there is the problems such as falling from high altitude hidden danger, it is characterized in that: between one end engaging lug of described casing fixer ring (3), be provided with articulated joints (4), other end engaging lug is provided with the circular hole of inserting bolt, is locked by nut (9); Two ends engaging lug fixedly mounts connecting rod (2), activity pressure baffle plate (6) cover is through on connecting rod (2), its center is provided with the screw matched with screw rod (5), the upper end of this screw rod (5) is provided with labor-saving grip (1), and its lower end is provided with the pressure fixing ring (7) of band lead-in wire watch window (8).Utilize the rotational pressure of screw rod to offset the elastic force of spring to end cap, have rational in infrastructure, easy to operate, time saving and energy saving, safe without advantages such as hidden danger, the replacing of inductance built-in type high pressure insurance can be widely used in.
Description
One, technical field
The utility model belongs to power construction auxiliary equipment, relates in particular to a kind of production safety, time saving and energy saving 35kV-PT built-in type high pressure fuse replacement aid.
Two, background technology
PT, also known as induction type voltage instrument transformer, adopts electromagnetic induction principle that the high voltage of electrical network main equipment is converted to low-voltage, thus realizes measurement, control, protective device to the monitoring of electrical network main equipment, is the visual plant of transformer station.Body is caused to damage and failure propagation when there is internal fault for preventing 35kV-PT inductance coil, high-voltage insurance need be set at PT mains side, but because the reason high-voltage insurances such as resonance, the long-time ground connection of circuit can fuse in running, now must change fusing insurance in time and avoid PT secondary voltage Loss.And outdoor 35kV-PT high-voltage insurance many employings built-in structure, change flow process complicated, effort is time-consuming.
Three, summary of the invention
The purpose of this utility model is for market provides a kind of rational in infrastructure, handling safety, fast and easily 35kV-PT built-in type high pressure fuse replacement aid.
The technical solution of the utility model is: it comprises the parts such as casing fixer ring, activity pressure baffle plate and connecting rod, articulated joints is provided with between one end engaging lug of described casing fixer ring, other end engaging lug is provided with the circular hole of inserting bolt, by nut locking; Two ends engaging lug has fixedly mounted connecting rod, the circular hole that a connecting rod is arranged through activity pressure baffle plate one end, the other end is provided with the band open slot circular hole through another root connecting rod, activity pressure baffle center position is provided with the screw matched with screw rod, the upper end of this screw rod is provided with labor-saving grip, its lower end is provided with pressure fixing ring, and this pressure fixing ring is provided with lead-in wire watch window.
The beneficial effects of the utility model are: not only rational in infrastructure, simple to operate, time saving and energy saving, and electric power overhaul personnel can be made when changing the insurance of 35kV-PT built-in type high pressure, follow one's inclinations and answer hand, reduce labour intensity, eliminate the potential safety hazard exposed in traditional work method, ensure that the person and device security, there is application value widely.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Four, accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1 is labor-saving grip, 2 is connecting rod, and 3 is casing fixer ring, and 4 is connector, and 5 is screw rod, and 6 is activity pressure plate washer, and 7 is retainer ring, and 8 is lead-in wire watch window, and 9 is nut.
Five, embodiment
As shown in Figure 1,35kV-PT built-in type high pressure fuse replacement aid is made up of parts such as casing fixer ring 3, activity pressure baffle plate 6 and connecting rods 2, articulated joints 4 is provided with between one end engaging lug of described casing fixer ring 3, other end engaging lug is provided with the circular hole of inserting bolt, is locked by nut 9; Two ends engaging lug has fixedly mounted connecting rod 2, the circular hole that a connecting rod 2 is arranged through activity pressure baffle plate 6 one end, the other end is provided with the band open slot circular hole through another root connecting rod 2, activity pressure baffle plate 6 center is provided with the screw matched with screw rod 5, the upper end of this screw rod 5 is provided with labor-saving grip 1, its lower end is provided with pressure fixing ring 7, and this pressure fixing ring 7 is provided with lead-in wire watch window.When implementing the utility model, casing fixer ring 3 only need be set on sleeve pipe by power equipment maintaining personnel, then lock with nut 9, recycle two connecting rods 2 be fixed on the engaging lug of casing fixer ring 3 two ends and the activity pressure baffle plate 6 passing connecting rod 2, make the pressure fixing ring 7 being arranged on screw rod 5 end be fixed on sleeve pipe, recycling labor-saving grip 1 rotates applying pressure by screw rod 5 and offsets the elastic force of spring to end cap.The advantage such as rational in infrastructure, easy to operate, safe and reliable, time saving and energy saving, has application value widely.
