Problems solved by technology

Among them, the principle of electric heating is to pass direct current through the cable, and the temperature of the cable can be raised by current heating. Bad cables, and it is easy to cause superposition of signals; liquid heating can be divided into water bath and oil bath, both of which are not easy to control the temperature of the liquid, and are likely to cause safety accidents

Embodiment Construction

[0009] Such as figure 1 A cable heating device shown includes an iron drum 1, an iron drum lid 2, and an adjustable electric furnace 3, and is characterized in that a row of temperature measuring holes 11 are arranged at intervals and evenly spaced along the height direction on the side wall of the iron drum 1 , in order to ensure that the tested cable is in a horizontal position, the size of each temperature measuring hole 11 needs to be adapted to the diameter of the wound cable, and the tested cable is wound to the corresponding temperature measuring hole 11; the iron drum cover 2 is distributed with temperature The adjustment holes 21 are used to adjust the temperature of the iron drum by adjusting the number of openings of the temperature adjustment holes 21 ; the adjustable electric furnace 3 is arranged at the bottom of the iron drum 1 .

[0010] Except for the technical features described in the instructions, all are known technologies by those skilled in the art.

Abstract

A cable -heating device comprises an iron bucket, an iron bucket cover and an adjustable electric furnace, wherein a row of temperature-measurement holes are arranged in the lateral wall of the iron bucket at intervals along the height direction, a cable to be tested is wound in the positions of corresponding temperature-measurement holes, temperature-adjustment holes are distributed in the iron bucket cover, and the adjustable electric furnace is arranged at the inner bottom end of the iron bucket. The cable -heating device has the advantages of guaranteeing the safety of test operation, being simple in operation and being easy to realize. Heating equipment is simple and low in cost. The heat generated by adjustable electric furnace is distributed in a gradient mode, and the test under the environment of steady state discrete temperature and transient temperature variation can be completed by adjusting the power of the adjustable electric furnace.

Description

technical field [0001] The invention relates to the field of mechanical mechanism testing, in particular to a device for heating cables. Background technique [0002] In the process of mechanical mechanism testing, the obtained measurement signal will be mixed with various uncertain components. Signal transmission carrier--signal cables are exposed to the external environment and are affected by many factors. In the prior art, the influence of environmental factors mostly focuses on the single influence of external electromagnetic interference. In the actual test process, the changing ambient temperature field directly acts on the signal cable. Electric heating and liquid heating are currently the most widely used methods for cable heating. Among them, the principle of electric heating is to pass direct current through the cable, and the temperature of the cable can be raised by current heating. Bad cables, and it is easy to cause superposition of signals; liquid heating ...
