Problems solved by technology
During the temperature rise test, the test cable is placed directly on the epoxy floor of the industrial plant, and the insulation level of the epoxy floor is low. If the test cable with high voltage is placed directly on the epoxy floor, there will be a discharge to the ground. If there is no professional test equipment to support the test cable and keep the test cable away from the ground, it will seriously affect the safety of workers and equipment

The invention discloses a testing tool, and the testing tool comprises a supporting plate, a supporting column, and a pedestal. The supporting plate is used for setting up test cables, and is provided with a separating part which is used for separating the adjacent test cables, so as to prevent the adjacent test cables from interfering with each other when the test cables are electrically connected. The upper end of the supporting column is connected with the supporting plate, and the supporting column is used for supporting the supporting plate away from the ground, thereby enabling the test cables on the supporting plate to be away from the ground by a certain distance, enabling the cable between the two adjacent testing tools not to contact with the ground, and reducing the impact on the safety of equipment and workers from a temperature rise test process. The pedestal is connected with the lower end of the supporting column. According to the scheme of the invention, the testing tool for a temperature rise test can enable the test cables to be supported away from the ground, and prevents the test cables from contacting with the ground, thereby preventing the test cables for discharging to the ground, protecting the equipment and workers, and improving the safety of the temperature rise test.
Description
technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a three-phase high-voltage cable temperature rise test tool. Background technique [0002] The temperature rise test is a test item of the transformer. The traditional temperature rise test evaluates the average temperature rise of the winding and the temperature rise of the oil top layer. If the measured values of these two temperature rises do not exceed the allowable temperature rise limit specified in the standard, then the transformer is considered to have passed the temperature rise test. type test. [0003] In the prior art, a temperature rise test is performed on a transformer through a three-phase temperature rise test device, and the transformer is connected to the three-phase temperature rise test device through a test cable. During the temperature rise test, the test cable is placed directly on the epoxy floor of the industrial plant, and the insu...
