Description
Technical field
The present invention relates to instrument, be specifically related to high voltage load switch change of fuse instrument.
Background technology
Along with the fast development of economic society, city network construction accelerates paces, and therefore 10kV high voltage load switch is also widely used.At present, the cartridge fuse of distribution load switch is arranged with vertical setting of types and horizontally-arranged two kinds.Due to limited space, the loading switch cabinet of vertical setting of types fuse series obtains a wide range of applications, vertical setting of types mode be cartridge fuse perpendicular to cabinet door, three cartridge fuses arrange from inside to outside.
A most important step of process fuse failure fault is exactly change the new cartridge fuse of three-phase.When changing vertical setting of types fuse because the power of extracting is vertical with the upper arm of operating personnel, causing stressed effect not in place, changing abnormal difficult.Because operating personnel need arm to put in high-voltage board, cause handling safety to have a big risk, this greatly have impact on breakdown repair progress.
Summary of the invention
The object of the invention is to: a kind of high voltage load switch change of fuse instrument is provided, utilize anchor ear that fuse is fastening, and realize changing with mechanical drive mode, reduce exerting oneself and security risk of operation, quick, the safety that realize fuse are changed, and solve high voltage load switch change of fuse length consuming time and the large problem of security risk.
The technical solution adopted for the present invention to solve the technical problems is: this instrument comprises fixed support, mechanical transmission mechanism and fuse retention mechanism, and fixed support is installed mechanical transmission mechanism and fuse retention mechanism, overall formation instrument; Described fixed support is made up of feet, rectangle frame and handle, and the dual-side of rectangle frame installs feet by handle is symmetrical; Described mechanical transmission mechanism rotates mouth by screw rod, supporting arm, pedestal and screw rod and forms, and the summit of two triangular bearing arm is separately fixed on pedestal, and another 2 of triangular bearing arm are movablely hinged on screw rod, and one end standing screw of screw rod rotates mouth; Described fuse retention mechanism is by underframe, more than half fillet anchor ear, spring, handle and sleeve pipe, the bottom centre of underframe connects a wherein pedestal of mechanical transmission mechanism, two, the bottom sleeve pipe of underframe connects rectangle frame, another pedestal of mechanical transmission mechanism connects the center of rectangle frame, underframe is symmetrically welded some more than half fillet anchor ears by pole, the two ends of handle penetrate the pole of more than half fillet anchor ear respectively, and one end of spring connects handle, and the other end of spring connects on underframe.
During work, mechanical transmission mechanism and fuse retention mechanism are fixed on switch cubicle by fixed support, and fuse retention mechanism, by fastening for fuse anchor ear, utilizes mechanical transmission mechanism extracted by fuse and insert.
The invention has the beneficial effects as follows: 1, structure of the present invention is simple, processing ease, and change consuming time short, security risk is little, fast and safely, reducing the interruption duration brought because changing fuse; 2, be inserted on switch cubicle by feet, thus kit is fixed on switch cubicle, by handle movable support pin, rectangle frame is fixed on switch cubicle; 3, rotate mouth rotary screw by screw rod supporting arm is unfolded or shrinks, operation concisely facilitates; 4, the fastening fuse of more than half fillet anchor ears, makes fuse to come off, and dismounting easily; 5, change of fuse instrument is used to solve the problem changing fuse length consuming time, preresearch estimates has a power failure less at every turn and calculates for 4.5 minutes, average load 2000kW, each comparable 150kWh that powered in the past more, to change 800 calculating every year, increasing income of electricity charge is 800 × 150 × 0.5=6 ten thousand yuan.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is theory structure schematic diagram of the present invention.
Fig. 2 is the fixed support schematic diagram of Fig. 1.
Fig. 3 is the mechanical transmission mechanism schematic diagram of Fig. 1.
