Abstract
The invention relates to a high reliable separation cabinet device for a voltage transformer of a switch cabinet. The high reliable separation cabinet device for the voltage transformer of the switch cabinet comprises a cabinet body, the three-phase voltage transformer, a trolley switch and a live display device. The trolley switch and the live display device are installed at the upper portion inside the cabinet body. The three-phase voltage transformer is mounted on the lower portion in the cabinet body. The upper end of the primary side of each phase of the three-phase voltage transformer is connected with a fuse, an insulating baffle is arranged between two adjacent fuses, and the upper ends of the insulating baffles are mounted on the trolley switch and the live display device. The high reliable separation cabinet device for the voltage transformer of the switch cabinet is reasonable in design and convenient to use, by the adoption of the high reliable separation cabinet device for the voltage transformer of the switch cabinet, occurrence of phase-to-phase faults of the voltage transformer in the cabinet is avoided effectively, the possibility of further diffusion of accidents is lowered, and the safe operation capacity of a power grid is improved greatly.
Description
Technical field
The present invention relates to electric information technical field, especially a kind of high-reliability switch cabinet voltage transformer partition shelf body device.
Background technology
Often can there is the fault such as Ferroresonance Damage in Systems or fuse melting in 10kV small current neutral grounding system; because voltage transformer three-phase equipment is in same switch cubicle; i.e. the same space; be easy to develop into phase-to phase fault (line to line fault or three-phase shortcircuit) by single-phase fault; and then the serious consequence of aggravation accident, the safe operation of harm electric power system.
Summary of the invention
The object of the invention is to make up the deficiencies in the prior art part, provide a kind of and effectively can prevent the high-reliability switch cabinet voltage transformer partition shelf body device that in cabinet, phase-to phase fault occurs.
The object of the invention is to be realized by following technological means:
A kind of high-reliability switch cabinet voltage transformer partition shelf body device, comprise cabinet, threephase potential transformer and car switch and charged display device, the top installation carriage switch of cabinet inside and charged display device, threephase potential transformer is installed in the below of cabinet inside, it is characterized in that: be all connected with insurance in the upper end of the primary side of the every phase of threephase potential transformer, between adjacent two insurances, be provided with insulation barrier, the upper end of this insulation barrier is arranged on car switch and charged display device.
And be all connected with lower connection row in the upper end of the primary side of the every phase of threephase potential transformer, on car switch and charged display device, opposite position is connected with and connects row, the two ends of insurance connects respectively arrange with under be connected row.
And, the described unsettled setting in lower end being arranged on the insulation barrier between adjacent two insurances.
Advantage of the present invention and good effect are:
1, this cabinet is connected with insurance in voltage transformer primary side upper end, the fuse melting when system generation overvoltage, and then plays the effect protecting voltage transformer not to be damaged.
2, this cabinet is provided with insulation barrier between adjacent two insurances, and this insulation barrier can, by mutually isolated for threephase potential transformer insurance in cabinet, make every only insurance form the relatively independent device space.When after generation single-phase fault fuse melting, due to the isolation of insulation barrier, effectively can prevent the generation of phase-to phase fault, thus reduce accident risk, ensure the safe operation of electric power system.
3, the present invention is a kind of high-reliability switch cabinet voltage transformer partition shelf body device reasonable in design, easy to use, this product effectively prevent the generation of phase-to phase fault in voltage transformer cabinet after running, the probability that the accident that reduces spreads further, makes electric power netting safe running ability be greatly improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
A kind of high-reliability switch cabinet voltage transformer partition shelf body device; comprise cabinet 4, threephase potential transformer 7 and car switch and charged display device 1; the top installation carriage switch of cabinet inside and charged display device; threephase potential transformer is installed, for system voltage measuring and protecting in the below of cabinet inside.
Innovative point of the present invention is: be all connected with insurance 5 in the upper end of the primary side of the every phase of threephase potential transformer, its concrete syndeton is: be all connected with lower connection row 6 in the upper end of the primary side of the every phase of threephase potential transformer, on car switch and charged display device, opposite position is connected with and connects row 3, the two ends of insurance connect respectively row with under be connected row.
Between adjacent two insurances, be provided with insulation barrier 2, the upper end of this insulation barrier is arranged on car switch and charged display device, the unsettled setting in lower end of insulation barrier.Insulation barrier by mutually isolated for threephase potential transformer insurance in cabinet, can form the relatively independent device space to every only insurance.
