Testing device for testing current-carrying capacity of automobile cable and maximum temperature rise of conductor during overload

Abstract

The invention discloses a test device for testing the current-carrying capacity of an automobile cable and the maximum temperature rise of a conductor during overload and belongs to the technical field of automobile cable test equipment. The test device is characterized by comprising a constant temperature room, wherein a constant temperature box is arranged in the constant temperature room, the constant temperature box comprises a detachable material simulation partition plate and a carrier frame used for installing a test cable, a box chamber is defined by the material simulation partition plates, the carrier is arranged in the box chamber, and temperature measuring elements are installed in the box chamber of the constant temperature room and the box chamber of the constant temperature box. The device can simulate the cable working environment of the new energy automobile so as to ensure that the cable measurement result is more accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of automobile cable testing equipment, in particular to a test device for testing the current carrying capacity of automobile cables and the maximum temperature rise of conductors during overload. Background technique [0002] With the development of the economy, automobiles have become an indispensable means of transportation in people's lives, and automobiles are widely popularized in the families of ordinary people. New energy vehicles use electric energy as the power source. They have the advantages of being green and environmentally friendly. They are not restricted by the urban traffic number restriction policy. They have become the first choice for people to buy cars. However, due to the instability of the electric energy storage and release process and the safety of the battery circuit itself, new energy vehicles have repeatedly experienced spontaneous combustion and smoke. This requires automakers ...
