Abstract
An assistance tool for high-voltage porcelain-housed fuse replacement relates to the field of power equipment maintenance. A base is composed of a clamping ring A (4) and a clamping ring B (6) which are fixed together by a bolt B (3) and a bolt C (5), and the clamping ring A (4) and the clamping ring B (6) are in threaded connection with a movable ring (1) through a bolt A (2) and a bolt D (7) respectively. The beneficial effects are as follows: the assistance tool of the invention has multiple functions, and is easy to use, safe and reliable, and simple in structure; a voltage transformer is added with a high-voltage fuse, and the high-voltage fuse can be safely, conveniently and quickly replaced in time after breaking; the power-off time of equipment is reduced, power loss is reduced, the reliability of power supply is improved, and the work intensity is lowered; a strong guarantee is provided for time-saving and labor-saving maintenance; and the assistance tool has a small size, is easy to carry during climbing, and has the advantages of being energy-saving, safe, beautiful, simplified, and the like.
Description
one, technical field
The present invention relates to electric equipment maintenance field, particularly one changes high voltage porcelain bushing formula insurance aid.
two, background technology
At present; 10-35kV voltage transformer adopts and installs high-voltage insurance additional and protect instrument transformer; but when needing to change after high-voltage insurance fusing; there is changing difficulty, complicated operation, needs many people carried out problems such as coordinating, the time is grown; because high-voltage insurance often fuses; but need at least two people to operate when replacing, and interruption duration is many more than two hours.
Voltage transformer high-voltage insurance body distance ground 4 ~ 5m, be fastened on support insulator by sleeve pipe retainer ring, work high above the ground face is liftoff at more than 3m, it is due to safeties internal structure, insurance both sides connect voltage transformer and bus by connecting line, inner both sides spring is in compressive state, because the spring force in sleeve body is very large, the single top cover that cannot make in high-altitude reaches normal installed position, and because of the restriction of the scope of operation, the one-sided many people operation in high-altitude cannot be realized, cause high-voltage insurance body cannot assemble in high-altitude, high-voltage insurance body must be dismantled to ground, one people is auxiliary offsets spring force, one people's dismounting insurance body, complete the replacing of insurance, the many employings of voltage transformer high-voltage insurance are built-in, bushing formula structure, replacing flow process is complicated, need dismounting 4 screws top cover could be opened during replacing, in order to make the contact of high-voltage insurance good, spring is placed at sleeve pipe top cover and strong room, due to the active force work that a people can not carry out installing separately after fuse replacement of spring, at least one people is also needed to coordinate, in order to head it off needs development to change high voltage porcelain bushing formula insurance aid.
three, summary of the invention
The invention provides a kind of high voltage porcelain bushing formula of changing for the problems referred to above and insure aid, its structure is: base is by snap ring A(4) and snap ring B(6) by bolt B (3) and bolt C(5) be fixed together, snap ring A(4) and snap ring B(6) respectively by bolt A(2) and bolt D(7) be threaded with loose collar (1).
The present invention uses like this: the top cover turning on fixing bushing side, after being taken out by the high-voltage insurance fused, puts into new high-voltage insurance; Take off loose collar (1), open Joining clasp A(4) and snap ring B(6) bolt B (3), by snap ring A(4) and snap ring B(6) be enclosed within the porcelain patticoat of sleeve pipe, by snap ring A(4) and snap ring B(6) fixing on the porcelain patticoat of sleeve pipe after to tight a bolt B(3), loose collar (1) is arranged on bolt A(2) and bolt D(7) on, the lid that bears down on one is being removed by nut Compressive activities ring (1), top cover compresses the spring in sleeve body, top cover is fixed on sleeve pipe, by the screw tightening of joint sleeve body and top cover; Take off aid; Change complete.
Beneficial effect of the present invention is: the present invention is multiple functional, esy to use, safe and reliable, structure is simple; Voltage transformer is adopted and installs high-voltage insurance additional, can change in time after high-voltage insurance fusing safely, easily and efficiently; Minimizing equipment interruption duration, decreases electric quantity loss, improves power supply reliable, reduces working strength; Complete service work provide powerful guarantee for time saving and energy saving, in maintenance process, the falling from high altitude of instrument after spring earth pressure release, can not be caused, 600 newton's stress can be born and deformation does not occur; Its volume is little, is convenient to ascend a height carry, and has the features such as energy-conservation, safe, attractive in appearance, simplification.
four, accompanying drawing explanation
Fig. 1 is structural representation of the present invention
In figure: 1, loose collar, 2, bolt A, 3, bolt B, 4, snap ring A, 5, bolt C, 6, snap ring B, 7, bolt D.
five, embodiment
Embodiment 1, a kind of high voltage porcelain bushing formula of changing insures aid, its structure is: base is by snap ring A(4) and snap ring B(6) by bolt B (3) and bolt C(5) be fixed together, snap ring A(4) and snap ring B(6) respectively by bolt A(2) and bolt D(7) be threaded with loose collar (1).The present invention uses like this: the top cover turning on fixing bushing side, after being taken out by the high-voltage insurance fused, puts into new high-voltage insurance; Take off loose collar (1), open Joining clasp A(4) and snap ring B(6) bolt B (3), by snap ring A(4) and snap ring B(6) be enclosed within the porcelain patticoat of sleeve pipe, by snap ring A(4) and snap ring B(6) fixing on the porcelain patticoat of sleeve pipe after to tight a bolt B(3), loose collar (1) is arranged on bolt A(2) and bolt D(7) on, the lid that bears down on one is being removed by nut Compressive activities ring (1), top cover compresses the spring in sleeve body, top cover is fixed on sleeve pipe, by the screw tightening of joint sleeve body and top cover; Take off aid; Change complete.
Claims (1)
1. change high voltage porcelain bushing formula insurance aid for one kind, it is characterized in that: base is by snap ring A(4) and snap ring B(6) by bolt B (3) and bolt C(5) be fixed together, snap ring A(4) and snap ring B(6) respectively by bolt A(2) and bolt D(7) be threaded with loose collar (1).
