Abstract
The utility model provides a transformer connecting device which comprises a casing. A salver is arranged on the side face of the casing, one end of a first connecting conductor is fixed on the salver, the other end of the first connecting conductor is connected with a contact seat, a transformer sleeve pipe is installed at the bottom of the casing, a transformer side shield is fixed at the top of the transformer sleeve pipe through a screw, and a second conductor is fixed on the transformer side shield through a bolt. A second connecting conductor is fixed at the top end of the second conductor through a bolt, and a first conductor is fixed at the top end of the second connecting conductor through a bolt and electrically connected with the contact seat. When in normal operations, the transformer connecting device serves as a connecting bus. In site tests, parts including the connecting conductors and the like in the transformer connecting device can be dismantled only from the position of a hand hole, and a nick can be formed. A nick shield cover of a transformer side and a gas insulated switchgear (GIS) side is the shield cover of the connecting device itself, and the shield cover does not need to be replaced, the casing does not need to be dismantled, and the transformer connecting device is convenient and quick to install, maintain and test.

Background technology
For Cubicle Gas-Insulated Switchgear (GIS) docks convenience, reliable with transformer; Realize that simultaneously GIS or transformer are separately during field test; Form fracture between transformer and the GIS, be necessary to design a kind of transformer jockey to solve the problems of the technologies described above.
The utility model content
The purpose of the utility model provides a kind of transformer jockey; It is convenient, reliable that it can make Cubicle Gas-Insulated Switchgear (GIS) dock with transformer; Realize that simultaneously GIS or transformer separately during field test, form fracture between transformer and the GIS.
To achieve these goals, the utility model adopts following technical scheme:
A kind of transformer jockey comprises housing, and the side of housing is provided with basin, and first bonding conductor, one end is fixed on the basin, and the other end is connected with contact base; The bottom of housing is equipped with bushing shell for transformer, and in the bushing shell for transformer top, second conductor dbus is crossed bolt in the transformer side shielding through screw in the transformer side shielding; There is second bonding conductor on the second conductor top through bolt, and there is first conductor on the second bonding conductor top through bolt, and first conductor and contact base electrically connect.
Second bonding conductor is a hollow cylinder, and its sidewall is provided with a breach, and a screening cover passes through screw in the breach of second bonding conductor.
The sidewall of housing be provided with one with the second bonding conductor installation site over against hand hole, through bolt the molecular sieve cover plate is arranged on the hand hole.
The basin and the first bonding conductor junction are provided with the basin shielding.
Said transformer jockey also comprises the shielding of GIS side, and said contact base is arranged in the shielding of GIS side.
With respect to prior art, the utlity model has following advantage: the utility model transformer jockey, when normal operation; As the usefulness of connection bus, during field test, be the parts such as bonding conductor in the dismountable transformer jockey only from hand hole; Can form fracture, and the radome of the fracture radome of transformer side and GIS side employing jockey self, need not heavily to change radome; Also need not to tear open housing, install, overhaul and test convenient, fast.
