Description
Technical field
The utility model relates to the portable fuse performance subtest stand of a kind of high-tension switch cabinet.
Background technology
High-tension switch cabinet refers to for electric system generating, transmission of electricity, distribution, electric energy conversion and plays the effects such as break-make, control or protection in consuming; high-tension switch cabinet is by making the electric equipment products of electric pressure at 3.6kV ~ 550kV; high voltage isolator and grounding switch, high voltage load switch, high pressure automatic reclosing and sectionaliser, several large classes such as high-voltage actuating mechanism, high-voltage explosion-proof power distribution equipment and high-tension switch cabinet.
High-tension switch cabinet has the functions such as built on stilts line, cable incoming-outgoing wire, bus contact.Mainly be applicable to various different field such as generating plant, transformer station, petrochemical complex, metallurgical steel rolling, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper etc.
High-tension switch cabinet should meet the relevant requirements of ac metal closing switch gear standard, is made up of cabinet and isolating switch two major part, and cabinet is made up of housing, electric elements (comprising insulating part), various mechanism, secondary terminals and line etc.
High-tension switch cabinet is divided into withdraw-type (handcart-type) and fixed by isolating switch mounting means; Be divided into indoor and outdoor by infield; The large class of metal enclosed armoured switch cabinet, the metal enclosed box switch cubicle of metal enclosed spaced switch Gui ﹑ and open type switch cubicle four can be divided into by cabinet body structure.
Electromagnetic potential transformer (TV) (for sake of convenience, becoming hereinafter referred to as voltage transformer (VT) or pressure) is widely used in, in the electric system of each electric pressure, being responsible for the functions such as measurement, protection in systems in which.In 10kV medium voltage distribution network, voltage transformer (VT), for detecting busbar voltage, generally occurs with the form of handcart switch cabinet, mainly contains and is arranged on handcart movable type and the fixed two kinds of mounting meanss of rear cabinet.
Long-term operating experience shows, 10kV electromagnetic potential transformer causes the accident that bus voltage transformer cabinet explodes to happen occasionally because of different types of Overvoltage, becomes one of the most common also serious voltage transformer (VT) accident.Accident often can cause main transformer switch, busbar sectional izing switch overstep tripping on bus, whole section of bus dead electricity, and the whole dead electricity of circuit, causes the serious consequences such as large-area power-cuts.
At present, the main safeguard measure of voltage transformer (VT) is at high-pressure side installing fuse.Fuse, as the simplest protective device, can protect electrical equipment from the infringement of overload current.Its structure comprises melt, shell and bearing etc., fills, and have the plenum space of 10-12% in cartridge fuse with silica sand particulate.Melt is made with the metal material that fusing point is lower, is series in protected circuit, and when overload occurs, melt heating fusing rapidly, cut-out circuit, reaches protection object.
For the explosion accident of voltage transformer (VT), current research mainly concentrates on carries out accident prevention from the angle avoiding resonance overvoltage to occur.But, due to the existence of all unpredictable factors such as operation of power networks state is ever-changing and fuse is off quality, make any prevention method all cannot stop the generation of accident at all.The analysis of many 10kV and 35kV power distribution network bus voltage transformer cabinets explosion accident is shown, typical accident process is: fuse pre arcing time under over-current state is long, blast after producing amount of heat, in the cabinet of pressure change simultaneously, the narrow space class of insulation is inadequate, fuse metal pile head is exposed, there is the possibility of point discharge, directly causes pressure to become the alternate puncture short of cabinet, finally cause the violent detonation of cabinet, bus overstep tripping accident.
Therefore, improve feasibility and the convenience of fuse ware-house-in inspection work, guarantee that warehouse-in spare fuse is qualified, become cabinet for minimizing 10kV handcart-type pressure and to be exploded the phase fault caused by fuse, the minimizing of bus dead electricity accident is significant.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, novel portable fuse performance subtest stand easy to use.
Technical solution of the present utility model is:
A kind of novel portable fuse performance subtest stand, is characterized in that: comprise base, handle, support insulator, axial grip busbar, radial clamping busbar and test line bank; The base left and right sides is provided with handle; Two support insulators are provided with above base; Be provided with axial grip busbar, radial clamping busbar and test line bank above support insulator, axial grip busbar, radial clamping busbar and test line bank 4 bottom surface are superimposed, and are fixed on the top of support insulator with securing member; Support insulator and base adopt bolt to fix.
Base and the handle of portable fuse performance subtest stand adopt securing member to fix.
The utility model provides a kind of rational in infrastructure, portable fuse performance subtest stand easy to use, feasibility and the convenience of fuse ware-house-in inspection work will be improved, guarantee that warehouse-in spare fuse is qualified, become cabinet for minimizing 10kV handcart-type pressure to be exploded the phase fault caused by fuse, the minimizing of bus dead electricity accident is significant.
The utility model scheme is reasonable, during use, is arranged on by fuse to be tested on portable fuse performance subtest stand, utilizes axial grip busbar and radial clamping busbar to clamp fuse to be tested; Line bank will be tested again be connected with peripheral test apparatus, and complete fuse performance test auxiliary rack and prepare.
