In order to achieve the above object, the technical solution adopted in the utility model is, this utility model provides a kind of hanging-rod type compact electrical transformers, including sealing the fuel tank arranged, device body general assembly it is provided with in described fuel tank, the top of described fuel tank is provided with high tension terminal, described high tension terminal is obliquely installed forward, it is additionally provided with low tension terminal on described fuel tank, described low tension terminal is arranged on the bottom of fuel tank, the back of described fuel tank is provided with mounting seat, the installation anchor ear being matched therewith it is provided with in described mounting seat, removably connect between described mounting seat and installation anchor ear.
As preferably, the back of described fuel tank is provided with the groove matched with electric pole, and described mounting seat is arranged on the both sides of groove.
As preferably, the outer wall of described fuel tank being provided with radiator, described radiator is corrugation radiator.
As preferably, described high tension terminal is high voltage porcelain bushing tubular type binding post.
As preferably, described low tension terminal is low pressure insulator tubular type binding post.
As preferably, the top of described fuel tank is additionally provided with hoisting ring.
As preferably, described high tension terminal horizontal tilt 60 ° is arranged on fuel tank.
As preferably, this utility model is applicable to less than 80 kilovolt-amperes.
Compared with prior art, advantage of the present utility model and good effect are,
1, this utility model is by changing the moulding of the shell of traditional transformer, change original double-rod stand mounting means into single pole fixed, save a large amount of installing space, reduce production cost, simultaneously, by improving high tension terminal and the position relationship of low tension terminal, it is ensured that the use safety of transformator, facilitate installation.
