Abstract
The invention discloses an insulating appliance for preventing error closing of a breaking swing-arm type fuse. The insulating appliance comprises a tail end and a front end. The tail end and the front end are connected through an insulating supporting rod, and the front end is a cylinder used for clamping a swing arm of the fuse. The insulating appliance for preventing error closing of the breaking swing-arm type fuse has the advantages that reliable insulation of the fuse can be ensured absolutely, and the transformation of the breaking swing-arm type fuse can prevent the situation that a circuit is connected by the error closing after the fuse is pulled aside and the due insulating and disconnecting function is not played. Thus, the insulating appliance ensures safety of personnel, equipment and a power grid and ensures normal orderly power supply.
Description
Technical field
The present invention relates to a kind of insulation utensil, more specifically, it relates to a kind of insulation utensil that prevents that disjunction swing-arm type fuse mistake from closing.
Background technology
Secondary circuits in substations disjunction swing-arm type fuse, comprise the combined floodgate fuse holder, presses step-down to press fuse holder etc., and due to the design of itself, each fuse holder pulls open and all is not fixed afterwards, and fuse does not directly take off.At electric substation's switch and in pressing the change maintenance process, disjunction swing-arm type fuse, must be very reliable and secure as secondary circuit and obvious isolating points of primary equipment.But in real service work, owing to pulling open disjunction swing-arm type fuse, fuse does not directly take off, monolateral unfixing, while carrying out other operations at the same time, may be due to vibrations, mistake is touched and is caused the fuse mistake to be closed, connect the former secondary circuit that should disconnect, may cause mistake to close circuit breaker or press become reverse charge, equipment and personnel being caused and have a strong impact on, in order very to determine the reliable of fuse isolation, disjunction swing-arm type fuse is transformed, prevented from pulling open after fuse the logical loop of mistake splice grafting and do not play isolation disconnection effect.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of rational in infrastructure, simple to operate, prevent from pulling open the insulation utensil that disjunction swing-arm type fuse mistake is closed that prevents in the logical loop of mistake splice grafting after fuse.
This insulation utensil that prevents that disjunction swing-arm type fuse mistake from closing, comprise tail end, front end, and described tail end is connected by insulating support rod with front end, and described front end is for blocking the cylinder of fuse spiral arm.
As preferably: described tail end is cuboid, and surface is provided with the No switching on sign.
As preferably: described each parts are the insulation material.
The invention has the beneficial effects as follows: can 100% determine the reliable isolation of fuse, to this transformation of disjunction swing-arm type fuse, can prevent from pulling open after fuse the logical loop of mistake splice grafting and not play due isolation disconnection effect.Thereby guarantee the safety of the person, equipment, electrical network, guarantee normally power supply in an orderly manner.
The accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is end view of the present invention;
Fig. 3 is vertical view of the present invention;
Reference numeral: tail end 1, insulating support rod 2, front end 3.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.Although the present invention is described in connection with preferred embodiment, should know, do not mean to limit the invention in described embodiment.On the contrary, the present invention will be contained alternative, modified model and the equivalent in the scope of the present invention that can be included in attached claims restriction.
As shown in Figure 1 to Figure 3, adopting the front end 3 of insulation utensil is cylinder (fuse model), adopts front end 3 and the tail end 1 of insulating support rod 2 connection devices.Insulation utensil tail end 1 is made cuboid, writes " No switching on " by the red color font in the above.
During work, open disjunction swing-arm type fuse, open circuit, be that front end 3 inserts former fuse position by barrel portion of the present invention, the spiral arm of fuse can be blocked, and makes in its groove that can not be threaded to fuse holder, so circuit can't be connected.Now, because cuboid tail end 1 of the present invention has obvious redness " No switching on " sign, can remind accurately and effectively the state of the current fuse of staff, prevent that fuse from closing the generation of accident by mistake.After end-of-job, the present invention is taken out, the fuse that closes, circuit is connected, and resumes work.
Claims (3)
1. one kind prevents that disjunction swing-arm type fuse from missing the insulation utensil closed, it is characterized in that: comprise tail end (1), front end (3), described tail end (1) is connected by insulating support rod (2) with front end (3), and described front end (3) is for blocking the cylinder of fuse spiral arm.
2. the insulation utensil that prevents that disjunction swing-arm type fuse mistake from closing according to claim 1, it is characterized in that: described tail end (1) be cuboid, surface is provided with No switching on and identifies.
3. the insulation utensil that prevents that disjunction swing-arm type fuse mistake from closing according to claim 1, it is characterized in that: described each parts are the insulation material.
