Abstract
The utility model discloses an outdoor transformer RW10-10/F series fuse decoupling prevention type locking device. A right-angled trapezoid type iron plate is arranged over a support on which two fuse hooks are installed, portions at which the inner sides of two rotating arms are jointed with hanging mouths of two fuse hooks are provided with a shaft limiting pin, the spindle end of each rotating arm on the right-angled waist side of the right-angled trapezoid type iron plate is provided with two rotating limiting pins respectively, the other end is provided with a zero electric pole supporting head lantern ring, the outer side of the middle portion of each rotating arm is provided with a spring hanger, and each of a rotating arm spring hanger and a right-angled trapezoid type iron plate spring hanger is installed with a spring separately. When rotating arms on the right-angled trapezoid type iron plate right-angled waist side are pulled and pushed by the zero electric pole supporting head up and down, the shaft limiting pins on the inner sides of the two rotating arms are locked downwards or left the hanging mouths of the two fuse hooks upwards, the moving range of fusion tube hanging shafts of the two fuse hooks is limited or cancelled, so not only the fusion tube hanging shafts are prevented from falling from the two fuse hooks in switch-on power supply conditions, and but also the fusion tube hanging shafts are taken out from the two fuse hooks in fuse replacement conditions.
Description
Technical field
The utility model relates to the mousing-hook locking device of outdoor transformer RW10-10/F series fuse hook.
Background technology
At present, it is larger that RW10-10/F series lower hook of taking of fuse that outdoor transformer uses and the hanging scroll of fusion tube lower moving contact touch the baffle ring gap, when closing power transmission with zero torch promotion fusion tube to brake application, the fusion tube hanging scroll is easy to come off from the fuse hook, cause repeatedly hook and may cause fusion tube from high-altitude landing, use time-consuming difficultly, and may bring potential safety hazard.
The utility model content
In order to solve the problem that fusion tube easily comes off from the fuse hook when using zero torch promotion fusion tube to close power transmission to brake application, the utility model provides a kind of outdoor transformer RW10-10/F series fuse mousing-hook locking device.This locking device can not only prevent effectively that the fusion tube hanging scroll from coming off from fuse hook, nor when hindering operation with fusion tube from the taking-up of fuse hook.
The technical scheme in the invention for solving the technical problem is:
above being installed, the two bearings of linking up with of fuse with bolt, the short right-angled trapezium iron plate in bottom side length bottom on 2 millimeters thick has been installed, the two hook of the upper base of right-angled trapezium iron plate and fuse outer rim is isometric, cut a breach on right angle, the upper base of right-angled trapezium iron plate and turned the width limiting valve as cursor, welded first a spring hangers downwards on right-angled trapezium iron plate right angle waist, connect the iron pipe of 5 millimeters of 7 millimeters internal diameters of an external diameter in the upper base side weld of right-angled trapezium iron plate, the iron pipe welding is placed in the inner of the two hook of fuse mouth hanging, pass iron pipe and installed the rotating shaft of a diameter 4 millimeters, riveting has filled a parallel cursor respectively at the two ends of rotating shaft, riveting has filled a limit pivot pin respectively at the two hook mouth hanging of the interior side engagement fuse of two cursors place, be provided with respectively two at the rotating shaft end of cursor and turn the width banking pin, turn each other the width limiting valve with base right-angle notch upper and lower surface on right-angled trapezium iron plate, the other end at cursor is provided with zero a torch fastener collar, in the middle part of cursor arranged outside second a spring hangers, on the second spring hangers and the first spring hangers, a tension spring has been installed.
When the collar that zero torch fastener inserts right angle waist one side cursor was done the up and down push pull maneuver, two cursors turned arc simultaneously up or down around rotating shaft.When cursor turns arc downwards, the mouth hangings of the two hooks of the downward locking fuse of limit pivot pin of the inboard of two cursors and cursor inboard, and locate under the acting in conjunction that turns width limiting valve and tension spring, define the moving range of fusion tube hanging scroll in the fuse hook, the fusion tube hanging scroll can not be come off from the fuse hook.When cursor upwards turns arc, the limit pivot pin of the inboard of two cursors and cursor inboard upwards leaves the two hook of fuse mouth hangings, removed the activity restriction of fusion tube hanging scroll in the fuse hook, and upwards locate under the acting in conjunction that turns width limiting valve and tension spring, opened wide the two hook of fuse mouth hanging, can take out the fusion tube hanging scroll this moment from the fuse hook.
The beneficial effects of the utility model are:This RW10-10/F series fuse mousing-hook locking device is lockable fuse hook mouth hanging both; prevent that effectively the fusion tube hanging scroll from coming off from the fuse hook; can remove the mouth hanging locking again; during convenient working, fusion tube is taken out from the fuse hook; reach protection equipment, handled easily, the purpose of power transmission quick and precisely.
