Abstract
The utility model relates to an insulated fixing device for a lead disconnection position during a preventative test of substation primary equipment. One end of a pull rod with an insulating sheath is connected with a metal screw. The diameter of the metal screw is slightly smaller than the diameter of a connecting bolt which connects the substation primary equipment with a lead. An insulating clamp body is fixed at the two ends of the lead disconnection position. The pull rod is perpendicularly connected with the metal screw. The insulating clamp body is chevron-shaped. Fixing bolts are respectively installed at the two ends of the insulating clamp body. The insulated fixing device for the lead disconnection position during the preventative test of substation primary equipment can solve the problem that the equipment is difficult to be disconnected with the lead in the existing method of using a rope, on the premise that test conditions are satisfied, the workload is greatly reduced and the work risk can be decreased; and since the pull rod is perpendicularly connected with the metal screw, the metal screw can be installed and detached conveniently, the speed is accelerated and the safety is further guaranteed.
Description
Technical field
The utility model relates to a kind of insulation stationary installation, the disconnected place of drawing of especially a kind of transforming plant primary equipment preventive trial insulation stationary installation.
Background technology
Domestic when at present transforming plant primary equipment being carried out preventive trial, be connected between needing off device and going between, existing method be off device with lead-in wire between be connected after, by rope lead-in wire is drawn back again and fix, but because lead-in wire is thicker, weight is heavier, remove and install difficulty, not only workload is big, and because is because by rope work but not insulating tool has increased the work risk.
Summary of the invention
Technical problem to be solved in the utility model provides the disconnected place of drawing of a kind of transforming plant primary equipment preventive trial insulation stationary installation, can solve off device is connected difficulty with lead-in wire problem, satisfying on the basis of test condition, reduce workload greatly, reduced the work risk.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the disconnected place of drawing of a kind of transforming plant primary equipment preventive trial insulation stationary installation, pull bar one end of tape insulation sheath is connected with metal screw, the diameter of metal screw is slightly less than transforming plant primary equipment lead-in wire coupling bolt, and the insulation clamp is fixed on the disconnected two ends, place of drawing.
Pull bar is connected with metal screw is vertical.
The insulation clamp is " mountain " font, and insulation clamp two ends respectively are equipped with set bolt.
The disconnected place of drawing of the transforming plant primary equipment preventive trial that the utility model provides insulation stationary installation, because the diameter of the metal screw of band pull bar is slightly less than transforming plant primary equipment lead-in wire coupling bolt, pull down the lead-in wire coupling bolt, off device can carry out again temporary fixed to lead-in wire with lead-in wire with the metal screw of band pull bar when being connected, be fixed on the disconnected two ends, place of drawing with the insulation clamp again, the disconnected connecting portion that draws the place has been played the effect of reinforcing and make it to be in state of insulation, solved the existing method off device of rope that utilizes and be connected difficult problem with lead-in wire, satisfying on the basis of test condition, reduce workload greatly, reduced the work risk; The design connected vertically of pull bar and metal screw has made things convenient for the installation and removal of metal screw, has accelerated speed, has further guaranteed safety.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the disconnected place of drawing of a kind of transforming plant primary equipment preventive trial insulation stationary installation, pull bar 2 one ends of tape insulation sheath 1 are connected with metal screw 3, and the diameter of metal screw 3 is identical with transforming plant primary equipment lead-in wire coupling bolt, and insulation clamp 4 is fixed on the disconnected two ends, place of drawing.
Pull bar 2 and 3 vertical connections of metal screw.
Embodiment of the present utility model is as follows:
At first take fixture wire place screw rod apart, use metal screw 3 to break to draw the two ends, place temporary fixed again, the space of enough insulation clamp 4 work is left in the position that the disconnected place of drawing that guarantees to take apart disconnects, again after temporary fixed the finishing, the clamp 4 that will insulate is placed in to break and draws the place, makes the middle clamp plate 6 of the centre of " mountain " font insulation clamp 4 be positioned at the position that the disconnected place of drawing disconnects, and tightens the set bolt 5 at insulation clamp 4 two ends again, 5 ' reinforces connecting portion, making the disconnected two ends, place of drawing be in state of insulation simultaneously.
Exist under a plurality of situations at fixture wire place screw rod, install after the step of a metal screw 3 removes the step of institute's leaded place bolt, the clamp 4 that insulate is installed in the manner described above again according to removing a bolt.
