Abstract
An installing structure of a transformer high pressure side current transformer coil comprises a high pressure connecting terminal, a high pressure insulator, a transformer fuel tank, a current transformer coil, a current transformer fixing device and a cable lead, wherein the cable lead is connected to the high pressure connecting terminal after passing through the current transformer coil and the high pressure insulator; and the current transformer coil is disposed in the transformer fuel tank. The installing structure significantly reduces the exterior height of the transformer after the transformer is installed, thereby facilitating the transportation.
Description
Technical field
The utility model relates to the transformer equipment field, and the high pressure of saying so is more specifically surveyed the installing area of current mutual inductor coil.
Background technology
Traditional transformer high-voltage is surveyed in the current mutual inductor coil installation, be current mutual inductor coil to be installed by welding rising seat on case lid, cause the transformer shipping height too high, need the dismounting bushing, reduce shipping height, sleeve pipe is installed at the scene then, and is very inconvenient, and so can make weld seam too much, in the transformer running oil leakage phenomenon appears easily afterwards.
Summary of the invention
The utility model purpose provides a kind of the reduction and becomes the mounting structure that transformer high-voltage is surveyed the current mutual inductor coil setting height(from bottom).
The utility model adopts following technical scheme for achieving the above object:
The utility model, a kind of mounting structure of transformer high-voltage side current mutual inductor coil, pass current mutual inductor coil, oil tank of transformer, high voltage porcelain bushing connection high-voltage connection terminal successively with cable tail, described current mutual inductor coil also is provided with the instrument transformer fixture outward, it is characterized in that described instrument transformer fixture is placed in the described oil tank of transformer.
Described oil tank of transformer internal fixation is installed folder.
Described instrument transformer fixture comprises: top board, bakelite screw rod, bottom plate, fixing angle steel, described fixedly angle steel is fixedlyed connected with described folder, described current mutual inductor coil upper end connects described top board, the lower end connects described bottom plate, described bakelite screw rod passes described top board), fixedly angle steel and bottom plate, and use nut check.
The utility model advantage: 1, adopt technique scheme, transformer measurement and protective current mutual inductor coil coil are installed in the fuel tank, reduced transformer external form height, make transportation convenient.2, reduced the welding job amount, reduced weld seam quantity after installing, reduced the transformer oil leakage phenomenon.
Description of drawings
The overall fixed structural representation of Fig. 1 step down side threephase current transformer coil coil; Fig. 2 is Fig. 1 end view;
Among the figure 1, high-voltage connection terminal 2, high voltage porcelain bushing 3, oil tank of transformer 4, top board 5, current mutual inductor coil 6, instrument transformer fixture 7, bakelite screw rod 8, bottom plate 9, cable tail 10, folder 11, fixing angle steel
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
Fixedly angle steel 11 as illustrated in figs. 1 and 2 is fixedlyed connected with described folder 10, described current mutual inductor coil 5 upper ends connect described top board 4, the lower end connects described bottom plate 8, and described bakelite screw rod 7 passes described top board 4, fixedly angle steel 11 and bottom plate 8, and uses nut check.
