Description
Technical field
The utility model belongs to field of electrical equipment, particularly relates in a kind of transformer station the high-tension switch cabinet of the connection device be used between isolation transmission line of electricity and transformer station.
Background technology
High-tension switch cabinet: refer in transformer station and be used for isolating the connection device between transmission line of electricity and transformer station.Comprise: cabinet, isolating switch, current transformer, breaker and arrester etc.
Along with improving constantly of substation equipment technical matters manufacture level, original old equipment having run two, 30 years will be substituted by new equipment by eliminating gradually.At present 10 KV distribution high-tension switch cabinets are for GG1A type in 66 kv substations run for many years, and the inner breaker installed is SN10 II type oil-minimum breaker.Requirement this kind of breaker run along with update and the non-oil ultra high vacuum system of substation equipment need be replaced by the more advanced vacuum circuit breaker of performance, existing technology is switch cubicle integral replacing, the drawback done like this is the power failure range expanding transformer station, adds construction investment.
Utility model content
Technical problem to be solved in the utility model is that providing a kind of ensures that avoiding transformer station to have a power failure, for a long time when changing breaker runs and the high-tension switch cabinet of cost saving on a large scale.
The utility model is a kind of high-tension switch cabinet realized like this, comprise cabinet, insulation disconnecting link A, insulation disconnecting link B, breaker and current transformer, outside cabinet, cabinet door place arranges insulated handle, breaker is arranged near cabinet door place, insulation disconnecting link A is arranged on cabinet top near cabinet door end, insulation disconnecting link B is arranged on the side outer circumferential side of the corresponding cabinet door of cabinet near apical position, insulation disconnecting link A inlet wire is connected to the side of current transformer by breaker, the opposite side of current transformer is by insulation disconnecting link B outlet, insulated handle controls insulation disconnecting link A folding by connecting gangbar A.
Further, the below that described current transformer level is installed on breaker is isolated by insulation board the utility model scheme.
Further, insulated handle controls insulation disconnecting link B folding by connecting gangbar B to the utility model scheme.
Further, described cabinet top is provided with insulator to the utility model scheme, is connected with the one end of the insulation disconnecting link A being arranged on cabinet top, and the other end of insulation disconnecting link A is connected to breaker one end.
Further, breaker is connected with the side of current transformer the utility model scheme, and the opposite side of current transformer stretches out the outside one end being connected to insulation disconnecting link B by bus of cabinet, and the other end of insulation disconnecting link B is connected with outer lead and exports.
Further, insulation disconnecting link A and insulation disconnecting link B arrange universal driving shaft respectively, and the gangbar connected by universal driving shaft is driven and realizes folding the utility model scheme, and described gangbar is connected with Handle axis.
The utility model compared with prior art, beneficial effect is: the isolation switch in switch cabinet body and cabinet, current transformer continue to use, isolation switch A installation site, end of incoming cables is constant, only end of incoming cables isolation switch A just can need be carried out rebuilding construction opening position when switch cubicle lead-in circuit breaker is changed.Under meeting the prerequisite of regulatory requirements electrical distance, its Proximity switch cabinet cabinet door is installed by the operating feature in conjunction with breaker, and change current transformer into level by traditional at right angle setting and install, leading-out terminal isolation switch is arranged on rear side of cabinet.To this ensures that there in switch cubicle reusing of except breaker is changed other equipment, make construction investment be reduced to minimum degree.
The utility model utilizes former switch cubicle to carry out inside transformation, and relevant device is reused, and reduces construction investment.Do not affect All other routes during construction normally to run, greatly reduce power failure range.
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the utility model embodiment provides.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See Fig. 1, a kind of high-tension switch cabinet, comprise cabinet 1, insulation disconnecting link A8, insulation disconnecting link B6, breaker 12 and current transformer 13, outside cabinet 1, cabinet door place arranges insulated handle 11, breaker 12 is arranged near cabinet door place, insulation disconnecting link A8 is arranged on cabinet top near cabinet door end, insulation disconnecting link B6 is arranged on the side outer circumferential side of the corresponding cabinet door of cabinet near apical position, insulation disconnecting link A8 inlet wire is connected to the side of current transformer 13 by breaker 12, the opposite side of current transformer 13 is by insulation disconnecting link B6 outlet, insulated handle 11 controls insulation disconnecting link A8 folding by connecting gangbar A10, insulated handle 11 controls insulation disconnecting link B6 folding by connecting gangbar B4.
The below that current transformer 13 level is installed on breaker 12 is isolated by insulation board 3.Cabinet top is provided with insulator 7, is connected with the one end of the insulation disconnecting link A8 being arranged on cabinet top, and the other end of insulation disconnecting link A8 is connected to breaker 12 one end.Breaker 12 is connected with the side of current transformer 13, and the opposite side of current transformer 13 stretches out the outside one end being connected to insulation disconnecting link B6 by bus 2 of cabinet, and the other end of insulation disconnecting link B6 is connected with outer lead and exports.Insulation disconnecting link A8 and insulation disconnecting link B6 arrange universal driving shaft A9 and universal driving shaft B5 respectively, and the gangbar be connected with universal driving shaft B5 by universal driving shaft A9 drives the coordinated signals realized disconnecting link folding of insulating, and gangbar is connected by axle with handle.
When needing to change breaker, operation insulated handle, to realize insulating opening of disconnecting link A and the disconnecting link B that insulate by driving gangbar A and gangbar B, thus the line of switch cubicle is disconnected completely, realize changing, after replacing, by insulated handle, insulation disconnecting link A and insulation disconnecting link B is in closed position, circuit realizes normal connection.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
