Problems solved by technology

However, conventional salt spray test chambers can only perform static tests, without special fixtures to fix the samples, and it is difficult to apply voltage to the samples
At the same time, the parameters of the salt spray cannot be automatically adjusted to meet the test requirements.
In addition, the existing salt spray test chamber cannot capture and record pictures and videos of leakage traces in time, and cannot make a complete and clear observation and record of the test

Abstract

The invention discloses a spraying electric mark resistance test device, which comprises a machine case, wherein a spraying chamber is arranged in the machine case, a left guide rod and a right guide rod are arranged in the spraying chamber, the lower side of the left guide rod is provided with a clamp device, the upper side of the right guide rod is provided with a spray seat, a spraying head is arranged on the spray seat, the clamp device comprises an upper clamp, a lower clamp and a base, the upper clamp and the lower clamp are of the same structure, a center hole used for fixing specimens and a guide rod ole matched with the left guide rod are formed in a base body of the base, and a microprocessor is also arranged on the machine case. The spraying electric mark resistance test device has the advantages that the specimens are fixed through the special clamps, so the specimens can exert voltage according to test requirements, the damaged conditions of cables and electric power fittings caused by electric marks due to surface electric leakage in filthy conditions are really tested, in addition, through the microprocessor, test parameters are automatically regulated, and rest results are automatically recorded, processed and output.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for cables and electric power fittings, in particular to a spray tracking resistance test device. Background technique [0002] In order to test the ability of cables and power fittings to withstand damage caused by electrical traces caused by surface leakage under dirty conditions, it is necessary to conduct a spray trace resistance test on power fittings. Since there is no special spray tracking resistance test device, the sample can only be tested in a conventional salt spray test chamber. However, the conventional salt spray test chamber can only perform static tests, and there is no special fixture to fix the sample, and it is difficult to apply voltage to the sample. At the same time, the parameters of the salt spray could not be automatically adjusted to meet the test requirements. In addition, the existing salt spray test chamber cannot capture and record the pictures and ...
