Description

A drain wire clip operating lever

technical field

The utility model relates to a drain wire clip operating lever, in particular to a drain wire clip operating rod for hanging and removing the drain wire clip during live work in a power system.

Background technique

Live work is a method of maintenance and testing on high-voltage electrical equipment without power failure. Live work is an effective measure to avoid maintenance blackouts and ensure normal power supply. Its content can be divided into several aspects such as live test, live inspection and live maintenance. Its objects include electrical equipment in power plants and substations, overhead transmission lines, distribution lines and distribution equipment.

Live work is divided into equipotential work (the human body is in direct contact with the high-voltage live part, and the staff should wear a full set of shielding clothing), ground potential work (the human body is on a grounded tower or frame, and the live work is carried out through an insulating operating rod) and intermediate potential work (through Tools such as insulating rods enter a certain area in the high-voltage electric field, but have not directly contacted the high-voltage electrified body).

Technical scheme of prior art:

Referring to Fig. 6, the existing drainage clamp insulating operating rod 30' has a special tightening rod pin 22', and a special inverted L-shaped groove 12' is designed for the tightening rod pin 22', after the tightening rod is completed, it is Rotate the insulating operating lever 30' to the left, and the tight rod pin 22' will slide down automatically.

Step 1: When using, first lift the inner sleeve to the horizontal groove along the vertical groove and move the nut to the left side of the horizontal groove to prevent the inner sleeve from falling down along the vertical groove. There is a groove at the upper end of the inner sleeve. At this time Align the horizontal pin 41 at the bottom of the drain clamp screw with the groove of the inner sleeve, rotate the insulating operating lever 30', and tighten the drain clamp screw.

Step 2: When the screw rod is tightened to the end, loosen the insulating rod slightly, and the nut on the inner sleeve will automatically move from the left side of the horizontal groove 13' to the vertical groove and slide to the bottom of the sleeve, and then continue to tighten the insulating operating rod 30 'Tighten the nut 42 on the drain wire clip.

Disadvantages of existing technology:

(1) During use, the operating lever should always be held up and fastened. If there is carelessness, the drainage clamp and the operating lever will be pulled apart. The drain wire is not fastened and will come out of the drain wire clip. At this time, the inner sleeve must be aligned with the screw of the drain clamp and tightened again.

(2) When the inner sleeve is separated from the screw of the drainage clamp, the inner sleeve slides to the bottom of the outer sleeve due to its own weight, and sometimes due to the friction between the inner sleeve and the outer sleeve, the inner sleeve is resisted and will not be very Smoothly slide down to the bottom of the outer sleeve.

(3) When tightening the nut and screw, there is no wrench fastening point at the bottom of the operating rod, and it is all tightened by both hands. In this way, the tightening force of the drainage wire clip is not enough, which may cause the phenomenon of false connection between the drainage wire and the main wire occur.
