Abstract

The utility model discloses a fixing plate for a tail wire of a transformer thermometer. The fixing plate comprises at least two positioning rods whose centers are positioned and connected through a positioning pin, wherein two ends of each positioning rod are respectively provided with a U-shaped clamping slot with an outward opening; and the positioning pin is arranged under the positioning rods, and is fixedly provided with a fixing clamp used for mounting the positioning rods on a transformer. The fixing plate provided by the utility model is used for solving the problems of breaking difficult fixation of the tail wire since the tail wire of the transformer thermometer is too long, and ensures the reliable connection of the tail wire of the thermometer.

Description

Transformer thermometer buttock line shaft collar

Technical field

The utility model relates to field of power, particularly a kind of transformer thermometer buttock line shaft collar.

Background technology

The loss that transformer is in operation in iron core and the winding is converted into heat energy, causes each position heating, elevates the temperature.Heat spreads towards periphery in modes such as radiation or conduction.Transformer thermometer is used for Real-Time Monitoring transformer and near temperature variations thereof.The buttock line of general transformer thermometer can remainingly have certain-length, in order to use from now on.Buttock line was not treated in the past directly hangs from above on the thermometer next door, and buttock line length may be run into ground makes troubles to staff's activity.Because wind-force and action of gravitation, buttock line can be twisted together, and easily hang on other device and cause buttock line to interrupt, and makes troubles for the measurement of temperature.

The utility model content

The utility model technical issues that need to address provide a kind of for solving the long and transformer thermometer buttock line shaft collar that causes buttock line to interrupt, be difficult to fix of transformer thermometer buttock line.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

Transformer thermometer buttock line shaft collar comprises at least two centers by the backstay of pilot pin location and connection, and the two ends of described every backstay are provided with the U-shaped draw-in groove of outward opening; The below that described pilot pin is positioned at backstay also is fixedly installed to be useful on backstay is installed in geometrical clamp on the transformer.

Improvement of the present utility model is: described backstay has three.

Improvement of the present utility model is: described pilot pin is the bolt with nut.

Because the technical progress of having adopted technique scheme, the utility model to obtain is:

The utility model provides a kind of stationary transformer temperature buttock line shaft collar, the buttock line that thermometer is more than needed is wound in the U-shaped draw-in groove of backstay, then will again shaft collar be installed on the shell of transformer, avoid the long buttock line of transformer thermometer because extraneous factor causes the generation of buttock line disruption, fundamentally guaranteed the buttock line firm and reliable connection of thermometer.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further details:

Transformer thermometer buttock line shaft collar comprises three backstays 1, and backstay 1 center is by pilot pin 2 location and connection, as shown in Figure 1.The two ends of every backstay 1 are provided with the U-shaped draw-in groove 3 of outward opening, and the cut-open view of backstay as shown in Figure 2.Pilot pin 2 is positioned at the below of backstay 1, is fixedly installed geometrical clamp 4 on the pilot pin 2.During use thermometer buttock line more than needed is twined in the U-shaped draw-in groove 3 of putting into backstay 1 along clockwise direction, and then shaft collar is installed on the shell of transformer.

Claims
