Abstract
An excitation transformer temperature measuring element fixing device comprises a polytetrafluoroethylene tube, a temperature measuring element and a temperature measuring line, wherein the temperature measuring element is arranged between a transformer high-voltage winding and a transformer low-voltage winding and is installed on a temperature measuring hole of the transformer low-voltage winding, the temperature measuring element and the temperature measuring line are arranged in the polytetrafluoroethylene tube, and the polytetrafluoroethylene tube is fixed between the transformer high-voltage winding and the transformer low-voltage winding through a nylon cable tie and/or epoxy resin adhesive. The excitation transformer temperature measuring element fixing device is simple in structure, the temperature measuring element is stably fixed, and a transformer temperature element can be prevented from causing the transformer high-voltage winding to be grounded.
Description
Technical field
The utility model relates to a kind of excitation and becomes the temperature element stationary installation.
Background technology
Existing generator excitation becomes temperature element and is on direct insertion transformer low voltage winding, lead-in wire and temperature element are not fixed, because Cooling Methods of Transformers is that bottom is toward up-draught and long-time low-frequency vibration, make temperature element easily break away from low pressure winding temperature measurement hole and take to the transformer high-voltage winding, cause the accidents such as high voltage side of transformer ground connection, cause that generator is non-to stop, affected power network safety operation.
The utility model content
The purpose of this utility model is to provide a kind of fixedly temperature element simple in structure, stable for the deficiencies in the prior art, prevents that the transformer temperature element from causing a kind of excitation of transformer high-voltage winding earth to become the temperature element stationary installation.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of excitation becomes the temperature element stationary installation, comprise polyfluortetraethylene pipe, temperature element and thermometric line, described temperature element is arranged between transformer high-voltage winding and transformer low voltage winding and described temperature element is arranged on transformer low voltage winding temperature measurement hole, described temperature element and thermometric line are arranged in described polyfluortetraethylene pipe, and described polyfluortetraethylene pipe is fixed between described transformer high-voltage winding and transformer low voltage winding by nylon cable tie and/or epoxide-resin glue.
Adopt said structure, this device is adopted polyfluortetraethylene pipe fixedly temperature element and thermometric line, teflon (F4, PTFE) has excellent electric property, good insulating, and polyfluortetraethylene pipe is hard tube, thereby reach fixedly temperature element, effectively prevent that the transformer temperature element from causing the function of transformer high-voltage winding earth, polyfluortetraethylene pipe is fixed mode by nylon cable tie and epoxide-resin glue, can guarantee enough machine intensity, and can not move.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As shown in Figure 1, described temperature element 3 is arranged between transformer high-voltage winding 5 and transformer low voltage winding 4, and this device is adopted polyfluortetraethylene pipe 2 fixedly temperature element 3 and thermometric line 1, teflon (F4, PTFE) having excellent electric property, is desirable insulating material; Polyfluortetraethylene pipe 2 external diameter 16mm, diameter of bore is 8mm; The thermometric line 1 of temperature element 3 passes through to transformer low voltage winding 4 thermometer hole tops in polyfluortetraethylene pipe 1, with the transformer low voltage winding, is close to; Polyfluortetraethylene pipe adopts nylon cable tie and epoxide-resin glue to be fixed mode above transformer, can guarantee enough machine intensity, and can not move; Polyfluortetraethylene pipe 2 adopts the corner pipe of 90 ° can flexibly temperature element be caused to needed position when turning to.
