Description

Switch cubicle plate washer opening device and special-purpose bus short-circuit grounding wire moving contact

Technical field

The utility model belongs to power industry power transmission and transformation instrument, particularly a kind of switch cubicle plate washer opening device and special-purpose bus short-circuit grounding wire moving contact.

Background technology

At present, its running status of switch in the switch cubicle that power industry electric substation uses is after the disconnecting link of switch pushes, on, following disconnecting link hole plate washer is opened, contact is connected with fingertip, when inspecting state, switch and disconnecting link are pulled out, on, following disconnecting link hole plate washer is sealing automatically under spring action, bump charging equipment to prevent personnel's false touch, because high voltage test need be carried out the nuclear phase operation in the disconnecting link hole that electric equipment is arranged, and need open the sealing plate washer artificially, generally want experienced operating personnel to wear insulating gloves, closely operation, press down the push rod against the force of the spring, the mode of using waddy to carry out the clamping stagnation connecting lever is carried out, and this kind method exists plate washer to open not exclusively and may be because of the not firm unexpected closing problem of jig clamping stagnation, the staff also easily because of falling, causes casualty accident.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of operating personnel's of preventing error shock is provided, and is flexible to operation, safe and reliable switch cubicle plate washer opening device and special-purpose bus short-circuit grounding wire moving contact.

The technical scheme that the utility model technical solution problem adopts is: switch cubicle plate washer opening device and special-purpose bus short-circuit grounding wire moving contact comprise dolly, base, slideway, the base alignment pin, earth connection, be characterized in establishing dead bolt on the base two sides on dolly, both sides, front at base are provided with handle, on the centre, divide into fixedly plate washer of plug, on, following plug is fixedly established the crank plug in the middle of the plate washer, the crank plug connects leading screw, leading screw and screw engagement, above base, establish the plate washer base, and move forward and backward with leading screw control, the plate washer base is established slideway on the two sides, plate washer base upper fixed switch cubicle plate washer is on the switch cubicle plate washer, following symmetry is respectively established three and is gone up nuclear phase working hole and following nuclear phase working hole; Moving contact is made up of the spring leaf of establishing in four contacts of right-angled intersection and the contact, contact and spring leaf center in right-angled intersection are together fastening with latch handle and earth connection link with bolt, symmetry is established two latches on the latch handle, in the T shape pin hole on the latch insertion action bars, on the earth connection link, fix an earth connection connector with bolt and nut, the earth connection connector connects ground wire, and earth connection end in addition connects earth clip.

The beneficial effects of the utility model are: switch cubicle plate washer opening device and special-purpose bus short-circuit grounding wire moving contact are because the switch cubicle plate washer places the dolly top, can advance evenly or pull out, the operating mechanism of plate washer rely on back-moving spring up and down each two connecting lever press down and on draw, gradually fixed contact is up and down closed.Establish six corresponding holes on the plate washer, be convenient to operating personnel and carry out the nuclear phase test, the cable end test, electrical verification, the special-purpose bus short-circuit grounding wire of mounting or dismounting, plate washer is pressed close to up and down the disconnecting link hole and is kept the safe enough distance with the dolly movable part, prevent that the operating personnel from slipping up or the unexpected upper and lower fixed contact that exposes that touches, guarantee operating personnel's personal safety.
