Abstract
The utility model relates to an insulation safety protective sleeve of a high-voltage circuit knife switch, which mainly solves the insufficiency that people who detect and repair on the high-voltage circuits are possible to be hurt due to the fact that the existing high-voltage circuit knife switches are possible to fall, after the existing high-voltage circuit knife switches are pulled up. The utility model is characterized in that an insulator (1) is a hollow prism, wherein the upper end of the hollow prism is closed and the lower end of the hollow prism is open. One side of the hollow prism is provided with a link rod leading-in opening (5), and a prism-shaped supporter (2) is arranged in the link rod leading-in opening. A cross inclined groove (3) and an inclined circular hole (4) are arranged on the supporter (2), wherein the cross inclined groove (3) forms an angle of inclination with a prismatic surface, the cross inclined groove (3) and the inclined circular hole (4) are positioned on the same slope, and the cross inclined groove (3) and the inclined circular hole (4) are mutually perpendicular. The utility model has the characteristic of effectively protecting the personal safety of people who detect and repair the circuits.
Description
Technical field:
The utility model relates to a kind of electric power safety protector used in the field produces field, especially relates to a kind of insulation safety protection tool that is used for when electric power system is overhauled on the high-tension line disconnecting link.
Background technology:
In oil recovery field, oil field, often to overhaul the high-tension line of working power is provided for oil pumper.During maintenance, need draw back disconnecting link earlier so that line outage, hang up the warning sign of No switching on, the workman could the upper boom maintenance then.But, in practical work process, because the fault of mechanical operating mechanism or artificial misoperation make originally to be fallen to overlapping by a disconnecting link that gets up, cause circuit charged sometimes, and therefore cause the serious accident of loss of life or personal injury.
The utility model content:
In order to overcome existing high-tension line disconnecting link the deficiency that may thereby cause the personnel that overhaul to come to harm of whereabouts is arranged after being pulled up on high-tension line; the utility model provides a kind of high-tension line disconnecting link insulation safety protective jacket, and this kind high-tension line disconnecting link insulation safety protective jacket has the effectively characteristics of protection circuit maintainer personal safety.
The technical solution of the utility model is: this kind high-tension line disconnecting link insulation safety protective jacket, mainly the prismatic insulator of hollow by a upper end closed, lower ending opening constitutes, have the link rod introducing port in this insulator one side, be built-in with a prismatic supporter that matches with its shape at insulator, on this supporter, have with prismatic surface and be the groove crosswise at oblique angle and oblique circular hole, wherein crosswise groove and tiltedly circular hole be positioned on the same inclined-plane and both are perpendicular.
The number of degrees at above-mentioned groove crosswise and oblique inclined-plane, circular hole place and oblique angle that prismatic surface is are spent between 90 degree 45, and best angle is 65 degree.
The utlity model has following beneficial effect: owing to be enclosed within on the high pressure disconnecting link that is pulled up after can utilizing instrument link rod commonly used in electrician's operation that the high-tension line disconnecting link insulation safety protective jacket of such scheme is propped up, even if make because the fault of mechanical operating mechanism or artificial misoperation make originally to be fallen to overlapping by a disconnecting link that gets up, circuit can be not charged yet, thereby effectively guaranteed line maintenance personnel's personal safety, can make the relieved work of maintainer, improve operating efficiency.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-insulator among the figure, the 2-supporter, 3-is groove crosswise, the oblique circular hole of 4-, 5-link rod introducing port.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this kind high-tension line disconnecting link insulation safety protective jacket, mainly the prismatic insulator 1 by the hollow of a upper end closed, lower ending opening constitutes, and the material of insulator 1 can be selected the High-Voltage Insulation heat-shrink tube for use.Have as shown in FIG. link rod introducing port 5 in a side of prismatic insulator 1, be built-in with one at prismatic insulator 1 and be all prismatic supporter 2, on supporter 2, have one and be the groove crosswise 3 at oblique angle and oblique circular hole 4 with prismatic surface, wherein crosswise groove 3 and tiltedly circular hole 4 be positioned on the same inclined-plane and both are perpendicular.The position of supporter 2 in insulator 1 should guarantee that groove 3 is positioned at and link rod introducing port 5 corresponding positions just with oblique circular hole 4 crosswise, like this, just can insert crosswise groove 3 so that the "T"-shaped head on link rod top can pass link rod introducing port 5 just and tiltedly in the circular hole 4, thereby this protective jacket can be provoked.In addition, also should make to be tight fit between insulator 1 and the prismatic supporter 2, so just supporter 2 can not take place and from insulator, come off out.
For the ease of being enclosed within on the disconnecting link, also should make the upper bottom surface of insulator 1 little, bottom surface is big, as a prism of dispersing.
Crosswise groove 3 and tiltedly the number of degrees at circular hole inclined-plane, 4 place and oblique angle that prismatic surface is can both guarantee that the technical program is achieved 45 when spending between 90 spend, but best angle is 65 degree, because under this angle, the operator just in time can the vertical lift link rod lifts high-tension line disconnecting link insulation safety protective jacket and is enclosed within on the disconnecting link that has been pulled up.
Insulator in the technical program can adopt the High-Voltage Insulation heat-shrink tube to be enclosed within on the mould and make after the pyrocondensation; supporter can adopt the High-Voltage Insulation bakelite to make; this test products obtains practical application in grand celebration nine factories of recovering the oil; be subjected to the lineman; safety manager and the leader's of enterprise favorable comment; everybody thinks that this product is lineman's a protector; filled up the blank of high-tension line disconnecting link insulation safety protection; its product conception novelty; simple in structure, applicability is strong, and is easy to use; safe and reliable, be suitable for promoting.
Claims (4)
1, a kind of high-tension line disconnecting link insulation safety protective jacket, comprise insulator (1), it is characterized in that: insulator (1) is the prism of the hollow of upper end closed, lower ending opening, the one side has link rod introducing port (5), it is built-in with a prismatic supporter (2), have one on the supporter (2) and be the groove crosswise (3) at oblique angle and oblique circular hole (4) with prismatic surface, wherein groove (3) and oblique circular hole (4) are positioned on the same inclined-plane and both are perpendicular crosswise.
