Description
Technical field
The utility model relates to the reaying protection test device (instrument) used in power system transformer substation maintenance, is specially multifunctional relay protection test car.
Background technology
In power system relay protection device verification, reaying protection test instrument is the most used, most important equipment.When Commissioning of Relay Protection personnel often see at protective calibration in substation, lift tester interval, the shuttling back and forth an of interval.Reaying protection test instrument weight has more than 30 jin, needs two people to copy mechanically, uses very inconvenient; And after good test apparatus, first need to access power supply, and ensure the correctness of power line voltage, also need to carry out wiring, test line after aptitude tests.But often because of wrong power supply in practical operation, and burn reaying protection test instrument; Meanwhile, also frequent because of mis-wired, produce the tuning error of verification protective relaying device, misoperation.
Summary of the invention
The utility model solves large, the inconvenient carrying of existing reaying protection test instrument weight, and the problem of mis-wired, wrong power supply easily occurs, and provides a kind of multifunctional relay protection test car.
The utility model adopts following technical scheme to realize: multifunctional relay protection test car, comprising that top is provided with can opening and closing case lid, bottom is provided with the draw-bar box of cardan wheel, reaying protection test instrument is fixed on the backboard in draw-bar box, draw-bar box top, power supply bobbin is supported with between biside plate, one end of power supply bobbin is provided with the rotary handle be positioned at outside draw-bar box, the side plate of draw-bar box or panel are also fixed with volt meter and battery socket, power supply bobbin is wound with power lead, the wire hole of one end on draw-bar box of power lead is drawn, the other end is connected with battery socket with volt meter, the testing wire storehouse of the useful baffle for separating in bottom of draw-bar box, the panel of draw-bar box has testing wire door, and each testing wire (comprising its power lead) needed for reaying protection test instrument is connected hub disk around in testing wire storehouse with reaying protection test instrument.During use, a people pulls draw-bar box to move easily, and pull-out power lead is connected to field power supply, and volt meter meeting display power supply voltage, can avoid wrong power supply; Open testing wire door, each testing wire is pulled out and the power lead of reaying protection test instrument is inserted on battery socket, test, verification can be started.After test, verification, rotate rotary handle and regain power lead, and coil back each testing wire, close testing wire door, directly can haul this test car by a people, to next proving ground, save time, human and material resources, improve the quality of verification.
Multifunctional relay protection test car described in the utility model, intuitively can show the current magnitude of voltage accessing power supply, effectively prevent wrong power supply to the breaking-up of protection test instrument, can reduce and loaded down with trivial details disconnect line (all testing wires comprise power lead is all prior have been connected in draw-bar box), prevent the mis-wired of protection test; Adopt the design of Portable draw-bar box cardan wheel, solve the problem of copying mechanically and collide with of work-site test apparatus, and then reduce labour intensity, improve work efficiency and the quality of relaying personnel.
