Technical field
The utility model relates to a kind of 35kV of being applicable to or 10kV rectifier transformer trunk primary side, that have current sense function (cable box) termination, belongs to the transformer technology field.
Background technology
At the transformer of steel industry operation, consider the running environment of transformer, for guaranteeing the safety of transformer, need current transformer and external cabling box be installed at primary side.Common way is that current transformer is arranged separately on the porcelain bushing bare bus bar, and then adds terminal box, because that transformer is installed in is indoor, above mounting means has the on-the-spot shortcomings such as complexity, poor stability, floor space are big, maintenance cost height of installing.If current transformer is installed in (built-in) on the transformer, externally install terminal box additional, consider the requirement of external belt electrical distance (particularly 35kV level product), transformer takes up an area of the space also can be very big, and for terminal box is installed, the transformer bulk volume also needs to increase, and causes the increase of production cost.Therefore floor space is installed, is reduced at the scene that how to reduce production costs, simplify, the reduction maintenance cost becomes a very importantly problem.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the multi-functional trunk termination that is used for the rectifier transformer primary side that low, the on-the-spot installation of a kind of production cost is simple, floor space is little, maintenance cost is low is provided.
Problem described in the utility model realizes with following technical proposals:
A kind of multi-functional trunk termination that is used for the rectifier transformer primary side, cable box and three-phase integrated current transformer assembly by the trunk shape are formed, described three-phase integrated current transformer assembly is by raise seat and be installed on its inner threephase current transformer and form of tubular, the described two ends that raise seat are connected with an end of oil tank of transformer and cable box respectively by flange, the middle part is provided with current transformer outlet terminal box, and the other end of described cable box is connected with the transformer foundation interface.
The above-mentioned multi-functional trunk termination that is used for the rectifier transformer primary side, at cable box with raise and between the seat flange to be set and to be welded, described flange be welded into the flat board of cable box flange coupling, flange is welded and is connected by the flange of bolt with cable box and dais.
The above-mentioned multi-functional trunk termination that is used for the rectifier transformer primary side, threephase current transformer is installed in the seat that raises side by side, each current transformer is connected with the rising seat with support plate through fagging, an insulating cylinder parallel with the rising seat successively, described insulating cylinder is opened wire hole towards current transformer outlet terminal box side, a bushing mounting flange is set in the end of incoming cables of each current transformer, and described bushing mounting flange passes flange and is welded and is connected with bushing.
The utility model current transformer is set to three-phase integrated built-in structure, and fit together with cable box, reduced transformer overall dimension greatly, it is that the cable box 1 of different cross section and the seat 16 that raises are linked together that the purpose that flange is welded is set, with traditional transformer current transformer is arranged separately on the porcelain bushing bare bus bar, the structure that externally installs terminal box additional is compared again, the utility model is compact conformation not only, floor space is little, field-mounted process is simple, installation period is short, and maintenance cost is low, and has improved the fail safe of fitting operation.
