Abstract
The invention discloses a breakdown-preventive metal protector for an insulator and application of the breakdown-preventive metal protector. The breakdown-preventive metal protector comprises a cover type shell and a conducting wire fixing groove. The conducting wire fixing groove is formed in the upper surface of the shell, the shell comprises two completely symmetrical half bodies, the upper portions of the half bodies are connected with each other by a bottom plate of the conducting wire fixing groove, and metal plates are stamped to form the upper portions of the half bodies. An application method for the breakdown-preventive metal protector includes mounting the insulator when lines are erected; placing flexible lining protection materials inside the cover type shell; enabling the cover type shell to be in flexible contact with the top of the insulator; directly sleeving the cover type shell on the top of the insulator; fixing a conducting wire. The breakdown-preventive metal protector and the application have the advantages that the breakdown-preventive metal protector is simple in structure, easy to manufacture, convenient to mount and low in cost; only the metal protector needs to be clamped on the top of the insulator when the power lines are mounted, so that the breakdown resistance of the insulator can be greatly improved, the possibility of breakdown of the insulator can be reduced, the power supply reliability of the power lines can be improved, and the safety of the power lines can be guaranteed.
Description
Technical field
The invention belongs to high and low pressure electric line equipment technical field, particularly relate to the anti-breakdown metal of insulator and protect part.
Background technology
Insulator is a kind of electric elements conventional in electric power system, insulator is generally to be formed by ceramic sintering, by porcelain vase and standing screw, formed, wire is directly banded on the groove on insulator, wire is generally steel-core-aluminium hinge line, the outside of wire is uneven, the part of protruding can produce great pressure to porcelain vase, and this part can produce stronger electric field, easily because point discharge punctures insulator, under powerful pressure-acting, insulator also may break, and power supply reliability and fail safe are all produced to great impact.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the anti-breakdown metal of a kind of insulator and protect part and application process, this metal being arranged on insulator protects part, strengthened the mechanical strength of porcelain vase, disperseed the pressure of wire to porcelain vase, evenly the electric field between wire and standing screw, played anti-breakdown effect.
The technical solution adopted in the present invention is: it is by covering sandwich type element and the wire holddown groove above housing forms, and housing is made by the two halves of full symmetric, and top is connected by wire holddown groove base plate, by metallic plate, is stamped to form, and shape is corresponding with insulator top.
Its application process is: during the construction of line, first installs insulator, in lid sandwich type element the inside, first places flexible lining protective material, it is directly enclosed within to insulator top, make to cover sandwich type element and insulator top flexible contact, and then fixing cord.
The invention has the beneficial effects as follows: simple in structure, easily make, easy for installation, with low cost; When power circuit is installed, only need on the card of the top of insulator, protect part by metal, just can greatly improve insulator and resist the ability of wearing, reduce the breakdown possibility of insulator, improve power circuit power supply reliability, ensure the safety of power circuit.
Accompanying drawing explanation
Accompanying drawing 1 is schematic diagram of the present invention; Accompanying drawing 2 is the vertical view of accompanying drawing 1.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.As shown in accompanying drawing 1,2, it is by covering sandwich type element 1 and the wire holddown groove 2 above housing forms, and lid sandwich type element 1 is made by the two halves of full symmetric, and top is connected by wire holddown groove 2 base plates, by metallic plate, is stamped to form, and shape is identical with insulator top.
During the construction of line, first install insulator, because metal protects part, have certain elasticity, can directly be enclosed within insulator top, and then fixing cord.During installation, in lid sandwich type element 1 the inside, first place flexible lining protective material, such as glass cloth, to ensure and the flexible contact of insulator, dispersible the pressure of wire to porcelain vase, the electric field between even wire and insulator standing screw.
Claims (2)
1. the anti-breakdown metal of insulator protects part, it is characterized in that: it is by covering sandwich type element and the wire holddown groove above housing forms, and housing is made by the two halves of full symmetric, and top is connected by wire holddown groove base plate, by metallic plate, be stamped to form, shape is corresponding with insulator top.
2. the anti-breakdown metal of insulator according to claim 1 protects part; its application process is; during the construction of line; first install insulator; in lid sandwich type element the inside, first place flexible lining protective material; it is directly enclosed within to insulator top, makes to cover sandwich type element and insulator top flexible contact, and then fixing cord.
