Background technology
Traditional instrument transformer mounting structure in switch cubicle, separates by horizontal baffle between the bus-bar room of switch cubicle and instrument transformer chamber, and instrument transformer is indoor A, B, C three-phase high-voltage bus, and while normally operation, bus-bar room is charged.1) now if change instrument transformer, just must be the disassembling bolts on the fixed head of two ends, instrument transformer left and right, and the afterbody of bolt is just in time positioned at bus-bar room, and therefore will remove bolt just must be first by after bus power failure, and personnel just can enter bus-bar room and remove this bolt.2) the indoor equal space of bus-bar room and instrument transformer is little, and maintainer installs and dismounting inconvenience.3) traditional mutual inductor installation structure, instrument transformer radiating effect is poor.4) switch cubicle is because the interior space is less, and difficulty when instrument transformer is installed, need to expend the more time, has reduced staff's operating efficiency; 5) current transformer itself is heavier, has potential safety hazard when installation, and careless manipulation will threaten staff's personal safety a little.6) switch cubicle is because the interior space is less, difficulty when instrument transformer is installed, and wiring is extremely inconvenient.
Utility model content
The utility model is exactly for the problems referred to above, provide a kind of simple in structure, cost is low, can reduce bus interruption duration, make instrument transformer good heat dissipation effect, mutual inductor interstar connection is convenient, installation and convenient disassembly mutual inductor installation structure fast.
For achieving the above object, the utility model adopts following technical scheme, a kind of mutual inductor installation structure that can reduce bus interruption duration, comprise switch cubicle, be arranged on the supporting piece on instrument transformer, switch cubicle cavity is separated into high voltage bus chamber and instrument transformer chamber by the horizontal baffle being arranged in switch cubicle, on described horizontal baffle, be fixedly installed two bolts, the U-shaped opening that described supporting piece one side setting and bolt match.
Between described instrument transformer and supporting piece, universal ball end being set is connected.
Described bolt one end arranges insulating barrier.
On described bolt, hold-down nut is set.
Hinged connecting rod is set in described supporting piece.
In described supporting piece, expansion link is set.
The nut of the utility model bolt is stuck in horizontal baffle, and fixes by fixture, in the time of dismounting or installation, need not open high voltage bus chamber hold-doun nut again, has reduced interruption duration, and dismounting and installation rate are fast; On described bolt, hold-down nut is set, makes bolted on horizontal baffle, increased the space of instrument transformer and horizontal baffle simultaneously, make instrument transformer thermal diffusivity good; The U-shaped opening that described supporting piece one side setting and bolt match, only need be arranged on supporting piece on instrument transformer when installation, and nut is arranged on screw rod, the U-shaped opening of supporting piece is snapped on two screw rods, tighten two nuts, install, installation rate is fast, has reduced interruption duration; Loosening two nuts are write in dismounting, and supporting piece is taken out, and change instrument transformer, do not need to open bus-bar room hold-doun nut, have saved the time, and overhaul efficiency is high; Between described instrument transformer and supporting piece, universal ball end is set and is connected, can make instrument transformer rotate at vertical equity, facilitate mutual inductor interstar connection; Hinged connecting rod is set in described supporting piece, makes connecting rod left-right rotation in the vertical, to connect instrument transformer good, connecting rod is fixed on instrument transformer, instrument transformer can not horizontally rotate, thereby has avoided mutual inductor interstar connection place to damage; In described supporting piece, expansion link is set, to connect instrument transformer good, connecting rod is fixed on instrument transformer, instrument transformer can not horizontally rotate, thereby has avoided mutual inductor interstar connection place to damage.
